Computers & Electronics
Since their birth, computers made distance learning possible. Due to this, many people were able to get higher education in different educational institutions of the world. Thanks to the internet, computer and electronics, many people work remotely. Accordingly, remote work offers people with health problems to work, without leaving home, in a cozy atmosphere.
Advantages and Disadvantages of Computers
The invention of the computer and electronics allowed to store a large amount of information, to easily copy it and transmit. Now there is no need to add thousands of documents in paper form since it can be saved on disk and have access to it when necessary.
Have you seen your friends for a long time? Using a computer, you can chat with friends and acquaintances or talk to them on Skype or through other programs. No matter where you are if you have a computer and access to the Internet, you will always be in touch.
Types of Computers by Function and External Parameters
A personal computer is a computer whose main feature is the use of a specific person (user), that is, personal use. Personal computers can be desktop or portable.
- Normal Desktop Computer (Desktop, all-in-one)
This type of computer got its name because of the need for its long-term installation in a specific place. Apparently, it was originally decided to install your computer on the table, whereas now only the monitor is mainly placed there. This type also includes desktop mini-computers (the size of the system unit is unusually small), computers with a horizontal system unit and all-in-one computers (a computer in the monitor).
- Portable Computer and Electronics
These types of PCs have become especially popular in our time, of course, the tendency to minimize the technology does not bypass anyone, but it is not always reasonable to pay for convenience.
The portable laptop is in the form of a flat block with an opening top. Laptops themselves, as a rule, differ from desktops in appearance, a touchpad (cursor pointer), the ability to work from the built-in battery and low weight (1.5-5 kg). Another feature of laptops - the high cost of components, and often the impossibility of self-changing broken parts.
Also, a portable laptop computer, but, unlike a laptop, a netbook does not have a floppy drive, it is equipped with an even smaller technical “body kit”, so it is inferior in power to previous types of computers. But this miracle of technology has even smaller dimensions and weight than a laptop.
- Tablet PC
Type of computer, which has become the defining property. This is a small flat candy bar with a decent diagonal screen (up to 10 ") controlled by a sensitive screen and side joysticks. Sometimes there are sliding tablets with a keyboard, but this is a more cumbersome device.
- Pocket PC (PDA)
In some way similar to a tablet computer, but rather combines a tablet + cell phone. The name is given to the device for a reason because the PDA quietly fits in the palm of your hand. This type of computer is not able to work with computer graphics, but they are not bought for this. PDAs support GPS, have Internet access, and are also equipped with various applications (mp3, video, voice recorder, camera, browsers, such as Opera, but for mobile devices). Controlled by touch screen/joysticks.
- Wearable computer (Microcomputer)
A portable device designed to solve specific problems, but recently received a part of the culture of universal computers (Internet applications, music applications, organizers). Until 2004, the most promising areas for the development of this type of computer were considered military and medical developments, but Korean scientists betrayed the device a new round of development, starting to create computers in the form of accessories, clothing, jewelry.
- Automated Workstation (AWP)
This type of computer means a computer or a group of combined computers that are part of one control system for something. Computers of this group are distinguished by enhanced details, for example, a multiplied increased memory size, a special powerful graphics card (for working with graphics and high-resolution video content), an extremely high-performance processor ( you can read about the processor device here) - for compilations, graphics processing. Similar computers also have a specific software suite of applications and environments for performing specific tasks in their area.
- Gaming Consoles
It has a structure similar to desktop computers but is strictly limited to the set of functions. The main purpose is to play computer games, although modern models make it possible to listen to music, play a movie or join the Internet. This type of computer does not have its own display, so it needs a video output device.
No one would argue with the fact that many types of computers made a big breakthrough in the field of technology and science. On production, it became possible to introduce new inventions that could reduce costs, save on the number of workers, and increase the quantity and quality of the products produced.
