Computer The computer occupied the entire world when it was invented and began to spread and enter into most areas of life because of the opportunities of work or even areas of development and progress were not notified to the human by the invention of the computer, and became the computer is the cornerstone in all fields of industrial, commercial and medical The computer is defined as a machine programmed to receive information through various input devices to process, store, and display results or outputs via output devices. The computer is used to express the person who performs the calculations. This concept remained until the end of the ninth century. When the European industrial revolution began, which caused the manufacture of many machines whose main purpose was to perform complex and simple calculations. [1] [2] The computer is made up of two main parts: the physical part and the programmative edge; each part depends on the other until it functions fully and naturally. The physical part of all the pieces that can be touched on a computer, such as: mouse, motherboard, hard drive, keyboard, audio speakers, screen, CD player, random access memory, read memory, cache, Scanner, printer, and other component parts of the computer; while the software part is the operating system in addition to the various programs and applications used on the computer, and the program part is not accessible. [3] The first computer in the world There is no comprehensive answer Asked when they were fed The first computer in the world, because of the existence of many different computer classifications, the first mechanical computer, for example, was manufactured in 18222 by Charles Babbage, but it is not like the computer we are dealing with in the present age, where the goal was to do a number of calculations and sports, In 1837 Charles also built a general mechanical computer based on analytical logic but was not supplemented by a lack of financial resources. In 1910, his son completed the construction of this mechanical computer to be able to complete basic mathematical calculations. [2] Between In 1936 and 1938, the German scientist Kwanrad Zoss named it Z11, the world's first electromechanical computer; but the famous British scientist Alan Turing set the foundation for computer work in 1936 when he invented a Turing machine that mimics a natural person after A series of logical instructions; that is to say, it programmed a machine to emulate man under certain conditions known as the software code, which is the main basis for all computers in the present era. In 1946 Tommy Flores created the Colossus, To decrypt encrypted German messages during the Second World War. [2] Based on the above, it is difficult to judge the first computer that was made because of the different types that appeared sequentially and sequentially; that some types of computer relied on other species to see the light, You can not imagine, for example, that laptops have emerged without relying on the various types of computers. But the Turing machine, the Z1 and the Charles Pappag computer are among the main points that caused the computer to appear and start its timeline. [2] ] computer types because of numerous computer types are D areas and uses that computer has become a major part of them, so many of the computers that meet the different needs and functions and tasks to be performed appeared, and computer types: [4] [5]
Personal Computer: A computer that is used by only one person. Desktop: A computer used in businesses and offices. Laptop (Laptop): It is one of the most widely used and common types of computers. It is small in size, portable everywhere and has a rechargeable battery. Mainframe: A huge device with a very large specification that supports many users at the same time. The server is the main device in different types of networks, and the server is a central device in various companies and factories; the other devices rely on access to files and the Internet. Personal Digital Assistants: A small computer; the main purpose of its use is to save titles and notes, and is characterized by the age of its long battery. Workstation computer: A computer with a very high specification; it is characterized by its great speed and perfect performance, and is mainly used in the operation of video games. The Supercomputer is the largest and most expensive computer. The supercomputer is the size of a room or larger. It is characterized by ultra-fast speed and excellent performance. These specifications have enabled it to become the main choice for simulating nuclear experiments or conducting scientific experiments. Require high accuracy and high speed to implement. [6]
