What is Moore's Law of Computers? What are the four components of a computer?

Some people who have just started to use the Internet think that computers are mysterious and seem to be very powerful. In fact, no matter how magical an object is, it has a basic working principle. For example, a computer is very similar to human thinking. It consists of four parts: a central processing unit, a memory, an input device, and an output device. What is Moore's Law for computers? Let's learn about it today.

What is Moore's Law for Computers?

Moore's Law refers to the number of transistors that can be accommodated on an IC, which will double approximately every 18 months, and the performance will also double. Moore's Law was discovered by Intel Emeritus Chairman Gordon Moore after long-term observation.

The First Law of Computers - Moore's Law In 1965, Gordon Moore prepared a report on the development trend of computer memory. He compiled an observation. When he began to plot the data, he found a surprising trend. Each new chip contains roughly twice the capacity of its predecessor, and each chip is produced within 18-24 months of the previous chip. If this trend continues, computing power will increase exponentially relative to time periods. People also found that this is not only applicable to the description of memory chips, but also accurately describes the development of processor power and disk drive storage capacity. This law has become the basis for many industrial performance predictions. In 26 years, the number of transistors on a chip has increased more than 3,200 times, from 2,300 in the first 4004 introduced in 1971 to 7.5 million in the Pentium II processor.

What are the four components of a computer?

It consists of four parts: central processing unit, memory, input device and output device. The central processing unit can be divided into controller and arithmetic unit.

The basic functions of the five parts:

1. Controller: The central nervous system of the entire computer. It interprets the control information specified by the program, controls according to its requirements, schedules programs, data, addresses, coordinates the work of various parts of the computer and the access to memory and peripherals, etc.

2. Arithmetic unit: performs various arithmetic and logical operations on data, that is, processes the data.

3. Memory: stores programs, data, various signals, commands and other information, and provides this information when needed.

4. Input device: Input programs, raw data, text, characters, control commands or data collected on site into the computer. Common input devices include keyboard, mouse, optical input device, tape drive, disk drive, CD drive, etc.

5. Output device: Output the intermediate or final results of the external computer, various data symbols and text or various control signals in the computer. Commonly used output devices include display terminals CRT, printers, laser printers, plotters, tapes, CD players, etc.

Is it useful to learn computer after graduating from junior high school?

It is useful to learn computer after graduating from junior high school.

After graduation, you can work in various enterprises, institutions, computer software companies and other industries, engaged in the planning and networking of computer network systems, the management and maintenance of network systems, the construction and management of various websites, the development of network application software, as well as the marketing and technical support of computer network related software and hardware.

Through 2 to 5 years of training, plus improvement and further study, you can become a network administrator, network engineer, web designer, etc.
