Abstract: Computer has turned to be the nerve of life and it has become an essential tool in each aspect and industry. This research paper aims at identifying the importance of computers, generations, components, and development. A computer is an electronic machine that can be programmed to process, store, retrieve, and perform mathematical and logical operations on data. Computers have endured huge developments in their different generations, the matter that has lead to the spread of personal computers with huge potentials in competitive prices. A computer consists of two main parts, which are hardware and software. Hardware components are tangible physical objects that we can see or touch, including motherboard, screen, mouse, and keyboard. Software is programs used to operate a computer, including application software, operating systems and programming languages. After recent technological developments, computers have become very small and cost-effective the matter why acquisition of computers has become more widespread. Keywords: computers, generations, components, electronic machine.
1. INTRODUCTION Currently, we live in this century what is called the information age, and the first and last credit for the spread of information with ease is due to the computer that is invented in the second half of the twentieth century by its English inventor Charles Babbage, where the computer became one of theindispensable things in this globalized and digital world and the revolution information and technology throughout all our tracks of life, as well as persons rely heavily on computers to facilitate all life processes and activities, and this is why the computer has become the nerve of life. Additionally, computers have become very important in the field of preparing accounts and budgets for companies and organizations. With time, computers have become something that can never be dispensed with. Computers differ in size and speed, and in the past, computers were distinguished by their large size, as it was the size of the room, and after the recent technological development, the computer became very small, and this is why the acquisition of computers has become more widespread, and its cost has become low. This paper is a detailed research about computers, their importance, generations, components, and development.
2. IMPORTANCE OF COMPUTERS A computer is an electronic machine that can be programmed to process, store, retrieve, and perform mathematical and logical operations on data. From here, it can be known that the computer is not limited to the known device that you see in offices and laboratories, but that the computer exists around us in many forms that we may not see directly, such as computers inside electronic games devices, exchange devices for banks, and means of transportation such as cars and airplanes, means of communication, media and others. In all of these images, the computer realizes data processing, storage, retrieval, and operations according to a specific program that follows its instructions. Hence, we realize that every computer must have three properties as follows: Programming - the ability to store and perform mathematical and logical operations - processing. But we will now turn to talking about the computer that is known to everybody.
