Types of Computer

1. desktop (Desktop)

Also called the desktop machine, it is a separate and separate computer. It is completely unconnected with other components. Compared with notebooks and netbooks, the host computer and monitors are generally relatively independent. Generally, they need to be placed on the computer desk. Or on a dedicated workbench. So named as a desktop. For very popular microcomputers, the machines used by most people's homes and companies are desktops. 

The performance of the desktop is stronger than that of a laptop. The desktop has the following features:

Heat dissipation. Desktops have the advantage that notebook computers can't match. The desktop chassis has been widely used because of its large space and good ventilation.

Scalability. The desktop chassis is convenient for user hardware upgrades, such as optical drives and hard drives. For example, the optical drive drive slots of the desktop chassis are 4-5, and the hard drive slots are 4-5. Very convenient for users to upgrade their hardware in the future.

Protective. The desktop protects the hardware from dust. And the waterproof is good; this development is not very good in the notebook.

Clarity. The open, key, reset button, USB, and audio interfaces of the desktop chassis are all in the front panel of the chassis, which is convenient for users.

However, the portability of the desktop is poor, which is very convenient compared to the notebook.

2. computer one machine

A computer is a computer consisting of a monitor, a computer keyboard and a mouse. Its chip, motherboard and display are integrated, and the display is a computer, so the machine can be used simply by connecting the keyboard and mouse to the display. With the development of wireless technology, 

The keyboard, mouse and display of the computer integrated machine can realize wireless link, and the machine only has one power cord. This solves the problem of many desktop cables that have been criticized for being criticized. Some computer-integrated computers also have TV receiving and AV functions, and also integrate special software, which can be used for specific industry-specific machines.

3. laptop (Notebook or Laptop)

Also known as a laptop or laptop, it is a small, portable personal computer.

Often weigh 1-3 kg. In addition to the keyboard, the notebook also provides a touchpad (TouchPad) or a pointing stick to provide better positioning and input functions.

Laptops can be broadly divided into six categories: business, fashion, multimedia applications, Internet access, learning, and special purposes. Business notebooks can generally be summarized as mobile, battery life, business software; fashion appearance is mainly for fashion women; multimedia application notebooks have strong graphics, image processing and multimedia capabilities, especially is the ability to play, for enjoyment products. Moreover, multimedia notebooks have more powerful discrete graphics and sound cards (both support HD) and have larger screens. Netbooks are lightweight and low-profile laptops with Internet access, e-mail and instant messaging (IM), and stream playback of streaming media and music. Netbooks emphasize portability and are used for mobile Internet access on business trips, travel, and even public transportation.

 The learning body is designed as a notebook shape, using standard computer operation, fully integrating learning machine, electronic dictionary, repeater, dot reading machine, student computer and other machine functions. Special-purpose laptops are models that serve professionals and can be used in harsh environments such as extreme heat, cold, low air pressure, high altitude, strong radiation, war, etc. Some are more cumbersome, such as the pre-Olympic Games at the "ASUS Everest Base Camp". IT service area" used by Asus laptops.

4. Pocket PC (PDA)

Pocket PC is a small, running on embedded operating system and embedded application software.

Lightweight, easy to carry, practical, and inexpensive handheld computing devices. It is simpler and lighter than a laptop in terms of size, function and hardware. In addition to managing personal information (such as contacts, plans, etc.), the handheld computer can also browse the Internet, send and receive emails, and even use it as a mobile phone. It also has: recorder function, English-Chinese Chinese-English dictionary function, global Clock control, reminder, entertainment, fax management, and more. The power of the handheld computer usually uses a common alkaline battery or a rechargeable lithium battery. The core technology of the handheld computer is the embedded operating system, and the competition among various products is mainly here.

Adding a mobile phone function to a handheld computer becomes a smart phone. In addition to the mobile phone's calling function, the smart phone also has PDA sub-functions, especially personal information management and browser and email functions based on wireless data communication. Smartphones provide users with enough screen size and bandwidth, which is convenient to carry around, and provides a broad stage for software operation and content services. Many value-added services can be launched, such as stocks, news, weather, transportation, goods, and applications. Program downloads, music picture downloads, and more.

5. Tablet

A tablet is a computer that does not require a flip, no keyboard, a different size, and a full-featured computer. It consists essentially the same as a laptop, but it uses a stylus to write on the screen instead of using keyboard and mouse input, and breaks the J-shaped design pattern of the notebook keyboard perpendicular to the screen. In addition to all the functions of a laptop, it also supports handwriting input or voice input, which is superior to mobility and portability. The tablet is proposed by Bill Gates , at least it should be the X86 architecture. From the tablet concept product proposed by Microsoft, the tablet is a PC that does not need to be flipped, has no keyboard, is small enough to fit into the ladies handbag, but is fully functional.
