SIZ EDUCATION ||what is computer and important information in computer.

A computer is a machine that calculates Count Estimate Count. In common parlance and writing, it is written and spoken by a computer. It is called (Arabic: Persian: French: Ordinateur, English: computer: Dator).

It is an electronic device that easily solves calculation questions and complex statistical problems, according to the prescribed and provided instructions, then either reveals the results of these calculations or saves them. In today's life computer is a tool used in general purposes which relies primarily on a microprocessor. The common purpose here refers to the use of computers in various devices in the field of life, because today the computer is not only in a personal computer (PC) but also in household electrical appliances and devices found everywhere including industrial and office premises.

Introduction.

Computer is a Greek word that means to compute or calculate. In the past, the word was also used for calculator, but in recent times, the term has been applied to a device (English: Machine) which, after inserting information into its own, a fixed Analyze them according to the strategy. That is to say, in other words, the computer cannot do anything on its own, but has to be told and explained what it does and how it works on the information and instructions we have been given.

The computer collects, stores and correlates the information we provide. The most important difference between an arithmetic and a computer is that a computer can store complex computer programs within itself and because of this feature it has the ability to perform logical analysis without human help.
Computers have completely changed the concept of computer monitors, keyboards and cases.

The two main features of a computer can be described as.

• It responds to instructions or programs delivered in a specific manner.

• It performs efficiently and effectively on the list of instructions (ie a computer program).

Ideal computer components.

An ideal computer has many components and can be studied by arranging them in different ways. A much better outline of structure and function may come to mind so these two sequences are given below.

In terms of structure.

The components that make up a computer in terms of physical structure can also be divided into two groups. One that counts internally and the other that counts externally.

External components.

• A computer display is a television-like component, also called a monitor.
• Case, which is a small box or box with monitor placed.
• A keyboard used to input information into a compute.
• Mouse is a small invention used for interaction or interaction with a computer .

Internal components.

• A motherboard is a board that holds the most important components of a computer, the CPU and memory.

• Processor (English: processor) is also called the central operating unit and CPU for short.
  Memory (English: memory), it is used as an electronic memory to store the work done in the computer.

• Graphics card (English: graphics card), an invention that is capable of displaying text as well as text (English: graphics)nowadays almost all video cards are of this type.

• Hard drive (English: hard drive), is a medium with high capacity that is used to store data.

• Compact Disc is an optical disk that has different types such as.

• CD-ROM

• CD-RW

• DVD-RAM

In terms of functions.

Thus the parts of a computer through which it performs its functions are all the components that are present in a computer. But basically it can be said that the most important functional parts of a computer are those with the help of which the central operating unit (CPU) performs its functions internally and can access the memory address. These active ingredients can be divided into three major groups.

Instruction set architecture.

• Microarchitecture.
• System design.
• Computer history.

Not a single invention or device can be said to be the first form of computer. The main reason for this is that the definition of computer has changed somewhat with the passage of time and that is why it is impossible to call a single computer the first computer. For example, many inventions that were once recognized as computers are not recognized today.

The term computer was originally used to refer to a person who could do calculations (see human computer) and often did so with the help of a mathematical invention such as a calculator or some other basic measuring instrument. ۔

Some mechanical inventions have also been used which can be said to be the most primitive form of computer or its development but they cannot be considered as computer by today's definition because they lacked any programmable style.

• Examples include abacus, slide rule, astrolabe, antikythera mechanism and various instruments made by Muslim scientists.
