Keyboard

Keyboard is a device designed to enter information from a user to a computer. A standard standard keyboard has more than 100 keys.

In addition to the standard keyboards, there are other types of keyboards that differ in the number of keys, design, material of manufacture.

Keyboard For those who have to enter a large amount of information throughout the day, the ergonomic keyboards will be useful - their structure is convenient for the hand.

For example, there are keyboards on which the keys are placed at an angle, keyboards consisting of two parts, which can be put as far from one another. There are keyboards with special holders under the palm of your hand. The only disadvantage of ergonomic keyboards is their price, because they are on average 2-5 times more expensive than the standard ones.

Multimedia keyboards contain a number of keys much larger than the standard ones. With the help of additional keys you can quickly open the folder "My computer", turn off the computer or put it in standby mode, start the calculator, media player, change the volume, the process of listening to music or watching a movie.

For those who spend a lot of time on the Internet, keyboards with special keys that facilitate navigation on the network will be useful. Also there are keyboards with special office keys that allow you to quickly launch office programs.

There is a special - a transparent and flexible keyboard, which can even be rolled into a tube.

The advantage of this model of the keyboard is the material of manufacture - rubber, which protects it from damage by liquid, ingestion of dust, crumbs or other small particles.

The keyboard can be divided into four main parts: alphanumeric, function keys, cursor keys and an auxiliary numeric keypad.

Let's now take a closer look at the keyboard, since with the keyboard we have to work very often, so you need to know the location and purpose, if not all, then at least the most frequently used keys.

Mouse manipulator.

Mice are harmful rodents, but there are other mouse-manipulators that move the cursor on the monitor screen, perform selection of objects and many more different actions.

To date, there are a huge number of different computer mice. They differ in size, design, number of buttons, shape, way of connection, etc.

Old models of mice were connected to the computer via the COM port, while the same mice connect to the computer via PS / 2 or USB connectors.

First of all, mice are:

- mechanical;

- optical and;

- radio mice.

Inside the mechanical mouse, the rubber ball touches the surface of the table and rotates the horizontal and vertical rollers, thereby giving information about the movement of the cursor. For such mice, you need a carpet (in the store: - do you have a mouse pad? And you do not need slippers for a cockroach?).

The optical mouse uses a light emitter. For them, the mat is not needed, they work on any flat surface.

Radio mice are connected to the computer via a radio sensor that is connected to the computer port. With the help of such mice, you can work with a computer at some distance from it, say, lying on a sofa. But a significant drawback of radio mice is the constant change of batteries
