INTRODUCTION

  

Information technology is a broad term that covers methods, means, computer techniques, telecommunications, programming techniques... to exploit and use rich and diverse information resources to serve human interests.

Information technology has a great influence on the continuous development of our country. It improves the efficiency of production, business and socio-economic activities.

Nowadays, Information Technology is gradually becoming popular and developing in most professions and in the training environment.

As we know, for a computer to work effectively for each need, it is necessary to assemble hardware components and install appropriate software. Realizing the importance of this, I chose the topic "Computer simulation, assembly and quotation software" with the desire to contribute part of the knowledge that I have about computer components to help those who are new to computer assembly and have more knowledge about computer configuration at each level.

CHAPTER 1: OVERVIEW

REASONS FOR CHOOSING THE TOPIC

In recent years, computers have played an increasingly important role in technical fields and daily life. The rapid development of both hardware and software technology has created new generations of machines that allow data collection and processing to be faster and more powerful. Thanks to computers, human labor productivity has increased significantly, they can replace humans to complete work quickly, which sometimes takes humans a long time to complete. Computers are so useful to humans, have users ever wondered: What is the structure of a computer? How is a computer assembled? What would it be like if we went to a computer store to assemble it?

Currently, the problem of assembling computers for individuals and organizations is mainly done manually at IT companies, which still has many shortcomings such as: no control over money, the assembled components may have excess features, etc. For individuals or families who want to assemble, they must seek advice from staff at the IT store or have to find components themselves to be able to buy and assemble.

When you assemble your own PC, you will get more benefits than buying a pre-assembled one. But it also requires you to have many things, the most important of which is the passion for learning because if you lack this personality, you will quickly give up when encountering problems (which often happens). Through "Computer simulation, assembly and quotation software", the purpose is to encourage young people to assemble or upgrade their own computers because only through this work can you learn a lot about the structure of the computer, how it works, and how to handle it when it breaks down.

Faced with such problems, I have built "Computer simulation, assembly and quotation software" to assemble and install computers to be able to answer my own questions as well as those of many people.

Topic “Computer simulation, assembly and quotation software”. Helps every individual have more opportunities to research, learn about technology and gain more knowledge about computer installation.

The software helps individuals know how to choose the right equipment to assemble a complete computer case with accurate technical parameters so that the computer runs at full capacity and runs more stably, helping managers to manage, add new and update devices on the system easily. In addition, the program also helps technicians accurately select missing equipment when repairing the machine without having to look for each device.

DEVELOPMENT HISTORY

For many generations, people have performed calculations with numbers mainly by hand or with rudimentary calculating tools (spreadsheets, rulers, etc.).

- In 1943, John Mauchley and his students built the first electronic computer in the US - the computer was named ENIAC (Electronic Numerial Itergrator And Calculator). It consisted of 18,000 electronic tubes, 1500 relays, weighed 30 tons, and consumed 140KW of electricity. This machine was intended to serve the military during World War II, but it was not completed until 1946. To this day, computers have made great strides, being applied in most social activities with many types of generations depending on the job. However, since then, computers can be divided into the following generations:

Generation 1:

- Technically: electronic components, low reliability, energy loss.

Calculation speed from several thousand to several hundred thousand calculations/second.

-About software: mainly use machine language for programming.

-About application: scientific and technical research purposes.

Generation 2:

-Technically: semiconductor components are mainly transistors. Memory has quite a large capacity.

big.

- Regarding software: started using some high-level programming languages: Fortran,

Algol, Cobol, ...

-About application: participate in solving socio-economic problems.

Generation 3:

- Technically: components mainly use integrated circuits (IC), peripheral devices are improved, magnetic disks are widely used. Calculation speed reaches several million operations per second; memory capacity reaches several MB (Megabytes).

- About software: Many different operating systems appear. Parallel processing. Diverse, high-quality software, allowing the computer to be exploited in many different modes.

-About application: participate in many areas of society.

Generation 4:

- Technically: Using VLSI (Very large scale integration) circuits, designing multi-processing structures. Speed reaches tens of millions of calculations.

/second. Here we are mainly talking about the IBM compatible computer architecture so the history of the PC is closely linked to the development of the IBM-PC. The personal computer has developed along with the development of microprocessors. The IBM_PC is considered to have originated from a project of IBM's Atlanta laboratory.

+ From 1979-1980 IBM completed the Datamaster machine. This machine used Intel's 16-bit microprocessor.

+ In 1980, the plan to produce PCs began to be implemented. The first IBM_PC used an 8-bit microprocessor from Intel, the 8085 VXL.

+ In 1981-1982 IBM produced PC computers using 8086,8088 microprocessors.

year

1984 computers use 80286 chip.

+ In 1987, computers used 32-bit 80386 CPU.

+ In 1990, the 80486 processor was born with more features.

+ In 1993, the Pentium processor was born, opening a new generation of personal computers with 64 bits of data and 32 bits of address.

+ 1995-1999 new generations of CPUs such as MMX, Pentium II, III with the ability to express

3D space, voice recognition...

+ Since 2000, with Merced, a generation of 64-bit CPUs with a completely new structure was born, creating a new generation of computers.
