Type and working method COMPUTER :
Computer types: -
Since the invention of the computer, many changes were made in its size till date. Before the computer was very large in size, its shape has become very small. Eg Desktop, laptop
There are three types of computers
1) Analog Computer
2) Digital computer
3) Hybrid Computer
The digital computer is currently being used mainly in all places. The digital computer was very low at the beginning of the speed. Now its speed has increased greatly. At present, more than 3 GHz computers are available in the market. The hybrid computer is used for showing something similar in general. Intel company introduced a computer named Pentium. Then it changed. He created a computer named Pentium-1, Pentium-2, Pentium-3, Pentium-4. Currently, there is a rapid change in the widely used Pentium 4, due to which the computer has become smaller and smaller. Like keeping a trumpet, the electronics component, select secondary storage devices, and input devices are inbuilt in small systems, in such a way that the notebook system, which is connected to the monitor by the Zodiac Monitor, outside the system, is called a laptop. Because the computer was small in size, it came in a laptop and it could be taken anywhere. Because laptop laptops are running on battery, it's easy to use it. The charging machine which has to be charged is charged for mobile charging.
Supercomputer: -
This is the most powerful type of computer. This computer is used in a number of specific organizations. Eg NASA employs this type of computer to keep control over space search campaigns.
Mainframe computer: -
It is used in an air-conditioned space. This type of computer is used to capture data. Eg Insurance company
Method of work: -
The computer has to go through 3 processes to do a job.
1) Input Device
2) c. P. U Central Processing Unit
3) Output Device
Device (Input Device): -
The department informs the computer to the information commander. It is necessary to provide the correct information to find the correct and accurate answer from the computer. The information that it is given includes keyboard, mouse, scanner, web camera, these parts.
C. P. U Central Processing Unit: -
The most important part of computing is to call this department a computer's brain. C. P. U The entire small electronics are made up of fortune. There are 42 transistor transmissions currently in the existing P-4. C. P. U They are two parts.
A) Arithmetic logic unit b) Control
A) Arithmetic Logic Unit: - This section is an important component of the computer. It is known only from the name that in this section, the information on the subject of mathematical and logic is checked, it is processed. All the mathematical operations such as sum, subtraction, multiplication, and division are done in this section. A number of comparisons are also drawn from two numbers.
B) Control unit: - The control department works to monitor all the action taken on the computer. As the human body keeps control of the brain, the control unit monitors all the movements of the computer.
The input section sends the central processing unit strictly for any purpose, so it is called the processing unit of the computer.
Output section: -
The information given by the input department will be processed from the Central Processing Unit and sent to the output department. Hence, he is known as the Computer Output Section. Ex: - Monitor, Printer
What is Hardware, Software?
Hardware is a computer connected to the electronics system. Eg Monitor, keyboard, hard disk, motherboard, cabinet, mouse, CD ROM, etc.
The software is a software that is controlled by the software used to convert the entire computer currency. Operating Systems (OS) is a program that runs a whole computer. No computer is available without the hardware and software of the computer. The luscious software is used by computers and people working on it.
Keyboard:
Keyboard: -
The keyboard is a computer's input device. It is possible to get help with your computer using the keyboard. The keyword is used to give information or specific instructions to your computer. The keyboard is usually a type of writer. As you type on the keyboard the characters come in the same screen. In the keyboard, some buttons have specific icons to remove.
Keyboard of the board consists of the following four parts.
1) Functional tree 2) Alpha pneumatic tree 3) Numerical tree 4) Cursor tree
1) Functional tree: - There are such functional keys in F1 to F2. These are all used for specific purposes only.
2) alpha pneumatic tree: - It has English frames from A to Z. There are a total of 26 and 0 to 9 numbers.
3) Numerical tree: - There are numbers from 0 to 9 and some special keys are used only for specific purposes.
4) Cursor tree: - This key is used if left to right, right, down, up.
On board, there are at least 83 and 127 buttons. There are 110 keys on the normal keyboard. Those keys that have more than 110 key keys on board are called multimedia keyboards.
The keyboard is connected to the previous part of the CPU. Keyboards are available in Normal, Peace / 2, USB and Wireless Port
In Windows XP, click on the Start menu, type OSK in Run, and press ENTER key, if you mouse click on a keyboard in a window, then only the key will be typed, which will be the type of key on which you click. Such as the keyboard that does not operate on your keyboard. On-screen keyboard works when you are not doing it.
