We live in modern society and we use gadgets everyday.
What are the types of modern computers
Nowaday there are different types of modern computers:
- Desktop computer
A desktop computer is a stationary PC for working at home or in the office. It is not designed to move from one place to another.
The desktop computer consist of:
- The monitor is a screen.
- The system unit is a plastic rectangular box with parts inside. This is the computer “brains”.
- The system unit is connected to the monitor via a cord (cable). And with the help of another cord, it connects to a regular outlet, because without electricity the desktop computer does not work.
- The mouse and keyboard are what we use to control the system. Connect directly to the system unit.
This is the minimum set of devices required for operation. But you can connect others: speakers, printer, camera.
- A laptop
A laptop is a small portable computer. It includes a screen, “brains”, a keyboard with a mouse substitute (touchpad) and built-in speakers. And most models have a webcam at the top of the screen. Complete with charger. This is such a special cord with a small power supply. One end of it is inserted into the laptop, and the other into the outlet. The laptop can work both with the help of the charger, and without it – from the battery.The battery is located at the bottom of the computer and allows you to use it without a network. But the charge does not last long – from two to six hours.
Smartphone – “smart” mobile phone. Through it you can not only make calls and write SMS, but also work in programs, use the Internet. The smartphone has a touch screen on which program icons are located. We press a finger on the icon – the application starts. And then we perform the necessary function in it. For example, there are applications for calls and correspondence: WhatsApp, Viber, Skype, Telegram. There are browsers: Google Chrome, Yandex, Safari. Social networks: Vkontakte, Odnoklassniki, Facebook, Instagram. And much more: weather, map, office applications, YouTube, etc.
The tablet is the same smartphone, only larger. Due to the enlarged screen, it is more convenient for reading, watching videos and working. Many users choose it as a replacement for a laptop, because it is lighter in weight and more compact.Control, as in the smartphone, touch. You can use the stylus – a special pen to press. The tablet is hardly suitable for “working” tasks: drawing up documents, working with graphics and sound, editing. But it’s convenient to watch videos and listen to music, read books and Internet pages, play games.
E-book – a device for reading, looks like a tablet or a large smartphone. The principle of operation is the following: we load files into it, open and read. And you can download not one or two books, but at least a thousand. Of course, you can read books on your smartphone or on the tablet. But the e-book is usually cheaper and more convenient in size. In addition, many models have a special screen that simulates a sheet of paper: it is more convenient to read from it and not so harmful to eyesight.
