1. Desktop computer is a stationary personal computer designed primarily for work in the office or at home. It means a system consisting of separate components: system unit, monitor, keyboard, mouse. Desktop computers are conventionally subdivided into subspecies: office computer, home computer, game computer. The division is certainly very imprecise, but first things first. Link how to choose a good computer ...

In an office computer, components of the lower price category are usually used, although there are exceptions - for example, in an organization working with AutoCad, 3d Max and similar complex graphics programs.

In home computers, they usually try to use more advanced components, for example, the overwhelming majority of them use a discrete video card, not integrated into the motherboard. Such computers are more often installed with a larger volume random access memory, larger in volume HDD offer a larger monitor.

The gaming computer is the most powerful, sometimes 8 Gigabytes of RAM are installed in such systems (only 64-bit systems support such a volume, all 32-bit systems support up to 4 GB, but in fact, about 3 GB of RAM is included in the work), there are instances and with 16 GB of memory. Also, several video cards are installed in such a computer, usually 2, but there are more. They try to install the top-end, most powerful video cards, configure them in SLI mode for Nvidia and Crossfire for video cards radeon... For tandem, they try to use the same video cards (often even from the same series). Several hard drives are also installed in the system. Now, fast SSD drives are becoming more and more available, they are small in volume, for example 160 GB, but their speed is much higher than that of conventional hard drives. Therefore, often in gaming computer install an SSD disk for the operating system, and, for example, 2 hard disks of two terabytes, operating in RAID 0 mode (a mode when information is written to 2 disks at the same time (the system sees not two disks, but one large one), giving a speed increase when work up to 30%). Installation of a water cooling system in such a computer is not excluded. This type of computer is the most expensive and is often assembled by enthusiasts. The image shows the inside of the gaming computer.

2. Nettop (English nettop) - a small physical size personal computer. The word "Nettop" is derived from "InterNET" and "deskTOP". The term nettop (similar to a desktop - a desktop computer) was proposed by Intel at the time of the announcement of Atom processors, which, in the understanding of this company, should become the main basis for creating nettops. A nettop is a stationary analogue of a netbook - a miniature network laptop. Typical examples of a nettop available on the market include the ASUS Eee Box, Acer and Crystal station AspireRevo - based on a combination of NVIDIA Ion chipset and Intel Atom processor. This type of computers, as well as stationary ones, are used in offices. Due to its small size, it can easily be placed on the back of the monitor, and given the fact that its cost is less than that of a stationary one, sometimes this is an ideal solution for an office. Of course, the performance of this solution is not as high as that of a full-fledged PC, but it is enough for office needs. Therefore, if you want to save space and budget, this is a good solution. The nettop image on the monitor is the optimal use of this small computer.

3. Monoblock computer. The structural diagram of a stationary PC in which the system unit, monitor and, at present, a microphone, sound speakers, webcam are structurally combined into one device - a monoblock. Such a PC is more ergonomic (takes up a minimum of space) and more attractive from an aesthetic point of view. Also, such a PC is more transportable than a stationary computer built according to a separate scheme.
The flip side of this medal is the relatively difficult scalability of such a PC, including the relatively difficult independent technical upgrade. Maintenance is also relatively difficult. For example, if a candy bar breaks, for example, a microphone, then it is often possible to replace it with a working one only in a service center. Naturally, monoblocks are widely used in cases where efficiency is in the first place, and simplicity of scaling or self-maintenance, on the contrary, is not decisive.

A monoblock is more often used at home, it is convenient in that it does not take up much space, therefore, a TV tuner is increasingly being installed in such a computer to watch television and rid the user of 2 items: a computer, a TV, combining them into one device. Also, this computer is able to save you from all kinds of radio tape recorders, CDs, DVD players. It is possible that your all-in-one computer will save you from the keyboard and mouse (some models are equipped with touch screens), but it will cost a lot. Of the minuses of these systems, of course, the price, while it is still quite high, for the same money, an ordinary personal computer will be more productive, but since such devices are gaining popularity, then the cost is steadily falling, and the performance is increasing.

4. (English Tablet PC) - a kind of notebooks that took shape after the presentation of the Microsoft Tablet PC hardware and software platform in November 2002. Equipped with a touch screen and allows you to work with a stylus or fingers with or without a keyboard and mouse. The main distinguishing feature of this family of PCs is hardware compatibility with IBM PC-computers and full-fledged operating systems installed on them, such as: Microsoft Windows NT family (Windows XP Tablet PC Edition, Windows 7); Apple Mac OS X; Linux (full desktop assembly of one of the distributions of this OS). Such operating system allows the user to use without restrictions any software available on the desktop computer.

They are mainly used by active people: they always need a personal computer at hand, and they are on the road all the time. It is mainly used as an addition to the main PC, not being the main PC. It is used as a multimedia accessory: they watch movies, read books, listen to music on the road, check their mail on the Internet.

5. Laptop (English notebook - notebook, notebook PC) - a portable personal computer, in the case of which typical PC components are combined, including a display, keyboard and pointing device (usually a touch panel, or touchpad), a pocket computer, and also rechargeable batteries. differ in their small size and weight, the battery life of laptops varies from 1 to 15 hours. Computer "Electronics MC 1504" in the form factor "Laptop" Laptop (English laptop - lap = knees of a seated person, top = top) or Portable - a broader term, it is applied to both laptops and tablet PCs. Laptops usually include laptops made in a folding form factor. The laptop is folded to protect the screen, keyboard and touchpad during transport. This is also due to the convenience of transportation (most often the laptop is transported in a briefcase, which allows you not to hold it in your hands, but hang it on your shoulder, for example). The idea of ​​creating a portable computer "the size of a notebook, having a flat monitor and able to connect to networks without wires" was put forward by the head of the research laboratory at Xerox Alan Key (Alan Key) in 1968. In 1979 by order of NASA William Mogridge (company Grid Systems ) created the world's first Grid Compass laptop.

Advantages of laptops over desktop PCs: Light weight and dimensions. Even laptops in the desktop replacement category can be easily relocated. A laptop can be taken on a business trip, to the country, on vacation. Moving a desktop computer to another room / office is often a challenge, let alone moving to another city. It is not necessary to connect external devices for operation. A laptop includes a built-in display, keyboard, and pointing device (usually a touchpad), but all of these devices must be connected separately to the desktop computer. Possibility of autonomous work. The presence of a battery allows the laptop to work in conditions when the electrical network is not available (on a train, plane, car, cafe and just on the street). A desktop computer can work autonomously for a very short time and only if there is an uninterruptible power supply. Ability to connect to wireless networks. Almost all modern laptops (with the exception of some ultra-budget models) are equipped with a built-in Wi-Fi adapter, which allows you to connect to the Internet without wires. There are Wi-Fi access points in many cafes, entertainment centers, airports, hotels. There are also city Wi-Fi networks that allow you to connect to a wireless network in many areas of the city. Desktop computers usually do not contain a built-in Wi-Fi adapter (with the exception of some expensive models and most nettops), however, this disadvantage is insignificant for stationary computers. Taken together, all the advantages of laptops over stationary computers make up the main quality of laptops: mobility.

6. Netbook (English Netbook) - a compact laptop with a relatively low performance, designed mainly for Internet access and work with office applications. It has a small screen diagonal of 7-12 inches, low power consumption, relatively low cost and light weight.
In terms of dimensions and functionality, netbooks occupy an intermediate position between mobile Internet devices (MIDs) and Handheld PCs “on the bottom” and subnotebooks “on top”. Netbooks differ from UMPCs in layout and, as a rule, use conventional touch-insensitive screens. This point is controversial, some manufacturers and experts classify netbooks and subnotebooks as UMPC. For most users, the most obvious differences from laptops will be: smaller dimensions, no optical drive (almost always) and the presence of a webcam with a microphone.

Netbooks use energy-efficient processors (ULVs) and chipsets. Almost all netbooks are equipped with wireless modules Wi-Fi networks, some are WiMAX, often there is a Bluetooth interface. Usually there is a multi-format (MS Pro, SD / MMC, XD-Picture Card) card reader. With rare exceptions (for example, Kohjinsha EX6, ASUS Eee PC 1004DN and to some extent HP Pavilion dv2), there are no optical drives. Netbooks use a variety of GNU / Linux operating systems (e.g. Eeebuntu, Ubuntu Netbook Edition, Chrome OS), Windows XP Home Edition and Windows Vista Home Basic (in some cases Windows Vista Business), and more recently Windows 7 Starter Edition, although the user can install any OS that is convenient for him. There is also support for many Android OS netbooks.

7. Pocket personal computer (PDA, English Personal Digital Assistant, PDA - "personal digital secretary", as well as Handheld computer) - a portable computing device with broad functionality. A PDA is often called a palmtop because of its small size. Initially, PDAs were intended for use as electronic organizers. At the moment, the classic PDA is almost completely superseded by communicators - PDA with a cellular radio module. It is impossible to make calls from the "classic" PDA, and the PDA is not a mobile phone. Now the name of the PDA as such is outdated - and now this device is called

A computer Is an electronic device that works with information and data. It can store information, process, receive, transmit, etc. You probably already know that with the help of a computer you can work with documents, by e-mail, play games, browse the web, and work with spreadsheets, presentations, watch videos, and more.

In this lesson, we will answer the basic questions that beginners have, such as what is a computer and what types of computers are there.

Hardware and software

Before going further, you should know about two important things: this is the hardware of the computer, or in other words "hardware", and the software or just programs with which we perform any tasks on the computer on a daily basis.

All your activities on the computer are related to hardware and software. For example, you are currently viewing this web page and are learning a lesson using web browser (software), and on your right hand you hold mouse(hardware) with which you can easily navigate through the pages.

Types and types of computers

When most people hear the word computer, they think of a personal computer or laptop. However, computers come in all shapes and sizes, and they perform different functions in our daily life. When you withdraw cash from an ATM, when your groceries are passed through a price scanner in a supermarket, or when you use a calculator. All these are also computers, but only of a different type and purpose.

Desktop computers

We use desktop computers at work, home, school, library, etc. They can be small, medium, large and are usually found on the table. It consists of a keyboard, mouse, monitor and system unit... Read more about what a computer consists of.

Most desktops are easy to upgrade and expand, or add new parts. Another advantage of desktops is their cost. If you compare a desktop computer and a laptop with the same functionality, you will most likely find that a desktop computer is cheaper.

Laptop computers

The second type of computers are laptops. Their advantage is that they are battery operated and are more compact, mobile and therefore can be used almost anywhere.

Since a laptop is smaller than a desktop computer, it will be more difficult to access the internal components. This means you cannot update or add new parts as easily as with a desktop computer.

Tablet computers

Tablet computers or simply "tablet". They are even more compact and mobile than laptops. Instead of a keyboard and touchpad, a touchscreen is used for typing and navigation. iPad is an example of a tablet computer.

The tablet cannot completely replace your home computer or laptop, because it will be more convenient to launch programs and work with documents on a laptop or desktop computer. But if you just want to play games, sit in social networks, listen to music and watch videos, then a tablet can be an excellent replacement for a computer for you.

Servers

A server is a computer that serves other computers on the network. Many firms, enterprises have file servers for storing information. The server can look like a regular desktop computer, or it can be much larger.

Servers play an important role in. They store web pages, sites, photos and videos. And they are responsible for their safety and loading time in the browser.

Other types of computers

There are many devices that are also mostly specialized computers, although we don't always think of them as computers. Here are some examples:

  • Mobile phones: Today they are able to provide you with many functions that previously could only be performed on a computer, for example, such as playing games, watching movies, etc. These phones are called smartphones.
  • Gaming consoles: A specialized type of computer used to play video games. While they are not as full-featured as desktop computers, many of them can perform tasks such as web browsing and Internet video.
  • TV sets: Many TVs now include programs and applications that allow you to browse the Internet or watch movies online.

Personal computers come in two flavors: PCs and Macs. Both are fully functional, but differ in appearance.

PC: The first such computer was called IBM PC which was released in 1981. Then other companies began to produce similar computers. Today it is the most common type of PC and uses the Microsoft Windows operating system.

Mac: These computers began to be produced in 1984 by Apple Inc. They are the first computers with a graphical user interface (GUI). They use the Mac OS X operating system.

In the age of high technology, computers occupy one of the leading branches in development.


Now scientists from all countries are working on their development, and the fruits of their activity are the emergence of new types of computers. Already, they can be divided into many categories, taking into account various parameters.

What kind of computers are there? It is possible to classify devices related to computers according to a huge number of criteria.

Size, power, functionality, purpose - all this is suitable for to characterize a specific group of computers... A modern person should understand this, because progress is progressing at a serious pace.

Types of computers

In everyday life, we are constantly surrounded by a variety of types of computers. They are found in modern cars and even in some wristwatches.

To differentiate between different types of computers, we divided them according to different parameters and put together explanations so that our readers understand this:

  1. Personal (desktop) computers are the most common type of computers. A common set of devices, interconnected by wires. For the system to work properly, you need a system unit, a monitor, a computer and a mouse.

  2. Tablet computers - appeared not so long ago and, as a rule, they are called simply "Tablet PC". In fact, they are no different from modern mobile devices, but they do not always have a SIM card slot.
  3. Gaming computers - that's what they call different types systems that are suitable for games. As a rule, powerful computers are called "gaming", since new games will not run on outdated systems.
  4. Laptops and netbooks - due to the battery, these devices can work autonomously. They differ from mobile devices in high performance. It is convenient that all the components are combined in one case.

  5. Monoblocks - practically do not differ from desktop computers, with the exception of appearance... To give the system an aesthetic design, the system unit and monitor have been combined.
  6. Nettops are small computers that are most often bought for offices. They do not take up much space and practically do not make noise, but most often they do not have high performance.


  7. Smartphones and PDAs - phones based on Android, IOS and other mobile platforms can rightfully be called computers. They also have a processor, RAM, and more. As for the PDA, it is the pocket version of the computer.
  8. Supercomputers - this is the name for entire systems in which several processors are installed or several computers work in parallel. The "Super" prefix is ​​added if the system performance exceeds 100 megaflops (1 megaflop - 1 million operations per second).
  9. Mainframes are huge computers designed for a variety of purposes. Now they are used for the complex work of a whole team of employees. Their century is long gone, they were popular until 1980.


  10. Game consoles - also refer to computers, earlier even the Dendi console was called a computer. Modern consoles offer much wider functionality (at least play multimedia).

These are what computers are, although you can think of many more criteria to add variety.

Now that you have figured out the types of such systems, it's time to find out. Inside any smartphone, laptop or candy bar, there are several components that ensure their operation.

Personal Computer is a complex electronic device designed to perform a wide range of tasks. This can be various calculations, calculations, listening to music, watching videos, various office tasks, games, and much more.

Personal Computer can be stationary or mobile. Mobile computers include laptops, netbooks, and tablets.

A desktop computer has also recently undergone changes, but in most cases it is a system unit, a monitor, input devices (keyboard and mouse), audio devices (speakers, headphones and a microphone), as well as other peripheral devices (printer, scanner, etc. .).

For the normal functioning of a personal computer, only a system unit, a monitor, a keyboard and a mouse are required.

An operating system is also required, in most cases they use Windows, but you can also download Linux.
Next, we'll take a closer look at each of these devices.

System unit

The main node personal computer is the system unit. It is a case, most often a metal vertical box, on the front panel of which there are power buttons and disk drives. All necessary connectors and cables are brought out to the back wall. The system unit consists of a power supply unit, a motherboard (also known as a motherboard or "motherboard"), hard disk(HDD), video card, processor (CPU), random access memory (RAM), disk drives (CD / DVD), sound card and network card. Often networked and sound card are performed integrated into the motherboard, that is, the radio elements of the board are wired directly to motherboard.

Power Supply

The power supply is made in the form of a separate box, which is located at the top of the rear of the system unit and has several power cables for all elements of the system unit.

Power Supply

Motherboard

The motherboard is the largest printed circuit board in the system unit, on which all the main components of the computer (CPU, RAM, video card) are installed, it also has connectors for connecting a hard disk and floppy drives, as well as USB port cables and connectors going to the rear panel of the case ... The motherboard performs the coordination of the work of all devices in the computer.

Motherboard

CPU

A processor is a microcircuit designed to perform basic computing operations. The processors are manufactured by two companies AMD and Intel. Depending on the manufacturer of the processor, the connector (the place of its installation) is also different, so you should not forget this when choosing a motherboard. You just don't plug an AMD processor into an Intel processor motherboard.

CPU

Video card

The video card is a separate printed circuit board installed in the PCI Express slot of the motherboard and is designed to display the image on the monitor screen. It processes the information received and converts it into an analog and digital video signal, which is fed to the monitor via a connector via a cable. A video card usually has a processor (GPU) and video RAM.

Video card

RAM

Random access memory is one or more small boards installed in special sockets on the motherboard (DDR). Random access memory provides temporary storage of intermediate data during computer operation. Random access memory is characterized by the speed of access and the amount of memory. By far the fastest memory is DDR3.

RAM

HDD

A hard disk is a permanent storage of data; it can be both user data and system or temporary data. The hard disk contains the operating system, without which the normal operation of the computer will be impossible. Also, the operating system can use the hard drive to save the contents of RAM (for example, in hibernation mode). It is a closed metal parallelepiped hard disk that is connected to the motherboard via a SATA connector.

HDD

Drive

An optical drive looks like a hard drive, but has a slide-out optical drive tray on the front panel. Serves as a drive for reading and writing optical discs.

The system board can also be installed with other additional devices, such as a Wi-Fi module or a TV tuner.

Monitor

The computer monitor serves for graphical presentation of information that is clearly understandable to the PC user. Recently, only liquid crystal displays (LCDs) have been produced. Monitors can be equipped with digital and / or analog video connectors (DVI, HDMI).

Keyboard

The keyboard is an essential input device for any computer. The keyboard is a group of keys for entering symbolic information. Also, many modern keyboards are equipped with additional keys, for example, to control media players and various programs.

Every more or less experienced user knows that there are different types of computers. In particular, they can be divided into stationary computers, nettops, monoblocks, laptops, netbooks, tablet computers and even PDAs, although these are gradually disappearing from the market and giving way to tablets and smartphones. Let's define what types of computers exist, and what are their main differences.

Personal Computer

This is a classic version of a modern PC, which consists of a system unit and a monitor. Mouse, keyboard, speakers are connected to the unit itself. Conventionally, such systems are subdivided into office, home, and gaming systems. Of course, such a division is very inaccurate, so you need to try to figure it out in more detail.

Office computers

To draw up a document, edit a file, keep accounting records - approximately these types of work are performed by a computer in an office, therefore, its components must be appropriate. For offices, the cheapest and weakest systems are selected, which are suitable only for working with office programs. However, if the company is engaged in drawing in programs such as Autocad, then offices can use more powerful systems.

Home

When choosing a PC for the home, users try to choose the most advanced systems and powerful components, good monitors. Most do not want to buy processors with integrated video cards, but prefer discrete cards. Home computer should be able to not only play movies and open documents, but even games. Such a system should also be equipped with a large monitor - spending time at such a computer at home is much more pleasant.

Gaming

These are the most powerful systems with a huge amount of RAM, a very powerful central processor and an expensive video card. Such specimens can be water-cooled (and not conventional air), since the components of such systems quickly heat up to high temperatures.

In some variants, several powerful video cards are used, which, thanks to Crossfire and SLI technologies, work together. Also, in such systems, new types of disks (SSD) are necessarily installed, which provide a higher speed of data access. Moreover, special types of screens are even used for them. Computers for games are equipped with cool monitors with a wide diagonal and minimal pixel response time. The most innovative to date is the 49-inch Samsung CHG90 GLED with a unique 3840x1080 resolution.

As for the amount of RAM, then gaming systems 16 or even 32 GB of RAM can be used, but this is not the limit either. Also, in a gaming personal computer, the types of memory should be the most modern. Today it is DDR4.

And all this applies only to personal computers. In this case, different types of platforms can be used. They can be based on AMD, Intel, Nvidia, Radeon components, and sometimes they can be combined with each other.

Nettops

This type of computer is distinguished by its compactness. Nettops are designed for work, poorly suited for home use, and completely unsuitable for gaming. In general, the term "Nettop" was introduced by Intel during the demonstration of its new Intel Atom processors, which, as the company representatives believed, should become the basis and basis for creating nettops.

If you give an analogy, then this type of computer is a stationary analogue of a laptop or netbook. These computers have traditional monitors, a mouse and a keyboard, but the system unit used is so small that it can be easily attached to the back of the monitor. As a result, the huge box is missing, which saves space.

Nettops are very weak computers that are equipped with budget hardware. Due to the low performance of the components, they heat up very little, which makes it possible to place them in a small box without efficient cooling. This box is neatly attached to the monitor. Due to the use of weak components, such systems are very cheap, so they are often bought for use in offices. They enable users to work with office programs, browsers, etc. You should definitely not expect high performance from them. Their main task is to ensure the ability of staff to work and at the same time save the company's budget. They do well with her.

Good examples of these types of computers are the following models: ASUS Eee Box, Acer AspireRevo AR1600. These systems are based on an Intel Atom chip and an Nvidia graphics card.

Note that although nettops are a convenient solution for offices, they practically did not take root. Most often, even in small companies for the needs of staff, they purchase cheap desktop computers with classic system units.

Monoblocks

This type of computer is very similar to a nettop, only in this case there is a screen, components, speakers, a webcam, and a microphone in a single case. Such a computer is ergonomic, takes up little space (at least, there is no awkward system unit), looks aesthetically pleasing. It is also more transportable than a regular desktop PC.

However, there are also disadvantages of such a device. At the very least, it is more difficult to repair and modernize. And if something breaks inside, then it will be very difficult to replace and even more to repair the component. If the candy bar is not under warranty, then you will have to pay for the repair service yourself, and it will cost more than repairing a classic desktop computer.

Considering the fact that such computers are most often bought for the home, TV tuners have recently begun to be built into them, which allow you to watch TV. That is, such a device combines a computer and a TV, which is convenient. More advanced computers are equipped with touch screens, which eliminates the keyboard and mouse altogether. The well-known monoblocks from Apple are popular, however, they are extremely expensive. By the way, the price is the main disadvantage of such systems. At a high cost, they use weak components, which, if they provide high performance, then only when performing routine tasks. You can't play games on such computers.

Tablet computers

Tablets are very popular today and are actively sold in their respective stores. It was originally thought that they would be used as a work tool, although in reality users buy them as multimedia devices. It is convenient to use tablets on social networks, the Internet, watch movies, read books. It may seem that a modern tablet is a smaller all-in-one, but, in fact, it is not. The monoblock has the ability to realize air cooling by installing fans. There is no such possibility in the tablet, so weak hardware is used here a priori. And although modern mobile processors are powerful, they are still inferior in performance to full-fledged ones.

Laptops

Most citizens have these portable personal computers. This is one of the most practical types of PCs and is very popular. There are many models on the market from different manufacturers.

A feature of the laptop is its portable case, which is divided into two parts: in one part there are components (it can be both powerful hardware and budget), in the other - the screen. Moreover, the type of computer screens can be any: with IPS, PVA, TN, MVA matrix, with large or narrow viewing angles, etc.

When it comes to accessories, there is also room for choice. For work or study, you can pick up a weak laptop with budget hardware, and for games, some manufacturers create quite expensive gaming platforms with efficient cooling and powerful components.

The difference between a laptop and a monoblock or nettop is not only its physical design, but also autonomous operation. Thanks to the use of the battery, the laptop can be operated on the street, in a cafe, at an institute. True, modern models are capable of working for three to four hours without recharging, but this is already quite good. Some standalone laptops can last 15 hours at a low brightness setting.

By the way, laptops in the West (and we also) are called laptops (laptop). They have certain advantages over stationary computers in the form of classic systems, monoblocks and even nettops:

  1. Low weight.
  2. Compactness and the possibility of transformation.
  3. Autonomy.

At the same time, laptops have the same capabilities as conventional stationary models. They are initially equipped with adapters for receiving a Wi-Fi signal, a webcam, and a keyboard (built into the body). The touchpad serves as a mouse, although a full-fledged mouse can be connected via the USB interface.

At the moment, many manufacturers are producing laptops. Products of brands Samsung, Acer, Asus, Lenovo are very popular. These companies offer a fairly large selection of laptops in the mid-range price range. Manufacturers such as MSI present notebooks at a high price point. They specialize in the implementation of gaming platforms with efficient cooling systems and the best hardware. Naturally, a computer with productive components can process any kind of information. And the fact that it was developed for games does not mean that you cannot work on it.

Netbooks

As laptops became very popular, some manufacturers took the bold step of downsizing their already compact devices. As a result, netbooks appeared - smaller counterparts of laptops that had 10-inch displays (most often the screen diagonal was just that). It is difficult to say what kind of work this type of computer does. Most likely, they were intended for Internet access, work with office applications, although their hardware was so weak that it was not possible to start a couple of unnecessary processes. Typically used in netbooks Intel processors Atom, which Intel previously made for nettops, found their way into netbooks as well.

And although such models were compact and very light, they very quickly disappeared from the market due to low demand. Today it is difficult to find a netbook in a store, as it is unprofitable to sell them. Everyone prefers to use classic laptops, despite the fact that they are larger and heavier.

Smartphones or PDAs

Earlier, only a few had a PDA (pocket personal computer). However, this gadget did not take root, as soon after its appearance, ordinary mobile phones were transformed into smartphones. They have improved, become affordable, so the need for a PDA has completely disappeared. In terms of their device, smartphones are very close to tablet computers and differ from them only in a smaller screen and the presence of slots for SIM cards, which allows you to make calls.

Finally

The personal computer and its types are constantly changing. It is possible that in the near future there will be some new type of PC that will revolutionize the field of digital technology. Sooner or later this will surely happen, because every year the components become more powerful and productive.
