Definition of CPU: Parts, History, and Functions

Definition of CPU – Currently, almost everything we do can be done by a computer device. When talking about the computer itself, it can’t be separated from the CPU. The existence of this CPU device can be said to be very influential because without a CPU, it is difficult for the computer to start. Then, what exactly is meant by CPU? Well, you can find the answer in this article, friend.

Definition of CPUs

CPU or Central Processing Unit is the most important part of a computer which is responsible for carrying out the instructions given to the computer. The CPU is the brain of the computer which is responsible for processing data and running programs ordered by the user.

In general, the CPU is responsible for controlling and processing data that enters the computer, as well as running programs ordered by the user. With the CPU, the computer can work according to the instructions given to it.

CPU Parts

The CPU consists of several parts that work together to carry out the instructions given to the computer, including:

1. CPU architecture

CPU architecture is the part that explains how the CPU works in carrying out the instructions given to the computer. The CPU architecture consists of several parts, including registers, ALU (Arithmetic and Logic Unit), and control unit.

2. Clock Speed

Clock speed is the maximum speed that can be achieved by the CPU in carrying out the instructions given to the computer. Clock speed is expressed in Hertz (Hz) or megahertz (MHz). The higher the clock speed that is owned by the CPU, the faster the CPU can execute the instructions given to the computer.

3. Cores

The core is the part of the CPU that is responsible for carrying out the instructions given to the computer. Currently, some types of CPU have more than one core, so they can execute more than one instruction simultaneously.

4. Caches

Cache is part of the CPU that is used to store data that is frequently accessed by the CPU. With the cache, the CPU can access data more quickly, thereby increasing the overall speed of the computer.

5. Heat sinks

Heatsinks and fans are parts of the CPU whose job is to keep the CPU temperature stable by absorbing the heat generated by the processor while it is working and removing it outside with the help of a fan.

6. Arithmetic Logic Unit (ALU)

The Arithmetic Logic Unit (ALU) is the part of the CPU that is responsible for performing simple arithmetic and logic operations, such as addition, subtraction, multiplication, and division.

7. Bus Interface Unit (BIU)

The bus interface unit (BIU) is the part of the CPU that is responsible for managing the flow of data between the CPU and other devices in the computer, such as memory, hard drives, and other input/output devices.

8.Control Units

Control Unit (CU) is part of the CPU which is responsible for controlling all activities that occur in the computer, such as reading instructions from memory, controlling data flow, and sending signals to other devices in the computer.

History of CPUs

The history of the CPU or Central Processing Unit originates from the development of computer technology in the 1940s. Initially, the CPU was a device consisting of several sets of electronic components that were used to carry out the instructions given to the computer.

In 1941, John Atanasoff and Clifford Berry developed a computer machine called the Atanasoff-Berry Computer (ABC), which was one of the first computer machines to have a CPU. The machine consists of several parts, among which are the memory, processing unit and control unit.

In 1943, John Mauchly and J. Presper Eckert developed a computer machine called the Electronic Numerical Integrator And Computer (ENIAC), which was the first computer machine to have a programmable CPU. The machine consists of several parts, among which are the memory, processing unit and control unit.

In 1951, the UNIVAC I (Universal Automatic Computer) became the first computer machine to have a separate CPU from other devices. The CPU in these machines is made up of several parts, among which are the memory, processing unit, and control unit.

In 1964, IBM released the first computer machine that had a microprocessor-based CPU, namely the IBM System/360. The CPU in these machines is made up of several parts, among which are the memory, processing unit, and control unit.

Since then, the CPU has continued to experience rapid development and has now become the most important part of any existing computer. The current CPU has undergone many changes in terms of design and specifications, so that it can work faster and more efficiently in carrying out the instructions given to the computer.

The modern computer was first created by a group of scientists and engineers who joined a computer project known as the ENIAC (Electronic Numerical Integrator And Computer) Project. The project was led by John Mauchly and J. Presper Eckert, two scientists from the University of Pennsylvania. The ENIAC project was developed in 1943 and launched in 1945.

Although the ENIAC was the first computer that was truly electronic and had the ability to perform data processing automatically, it was not truly a “modern” computer as we know it today. The real modern computer appeared a few years later, having developed the concepts that form the basis of modern computers such as memory, programs, and operating systems.

Several other figures involved in the development of modern computers include:

  • Alan Turing: British scientist who designed the first theoretical computer known as the Universal Turing Machine.
  • John von Neumann: Hungarian mathematician who designed the first computer to use main memory to store programs as well as data. This design later became the basis for modern computers.
  • Grace Hopper: American computer engineer who designed the first programming language known as COBOL (Common Business-Oriented Language).

All of these figures were credited with the development of the modern computer, although not all of them were directly involved in creating the first truly electronic computer.

CPU (Central Processing Unit) is the main part of a computer that is responsible for processing data. The first CPU was developed by the Intel Corporation in 1971, and was known as the Intel 4004. This CPU was made by Robert Noyce and Federico Faggin of Intel.

Since then, CPUs have been continuously developed and improved, and today there are many manufacturers developing CPUs with different specifications. Some of the leading manufacturers in the market today include Intel, AMD, and ARM.

The inventors of the first CPU that can be said to be the “first people” were Robert Noyce and Federico Faggin from Intel, who designed and developed the first CPU known as the Intel 4004. However, the development of the CPU did not happen suddenly, but was the result of many years. research and development carried out by many people, especially scientists and electronics engineers.

The development of the CPU (Central Processing Unit) has occurred since 1971, when Intel released the first CPU known as the Intel 4004. This CPU was the first CPU that was truly electronic and could perform data processing automatically. Initially, the CPU was only able to handle basic instructions such as addition, subtraction, and comparison, and did not have very complex capabilities.

Since then, CPUs have been continuously developed and improved. In 1974, Intel released the CPU under the name Intel 8080, which was the first CPU capable of handling more complex instructions. This CPU later became the basis for the first computer known as the Altair 8800, which was the first computer to be sold en masse to consumers.

In 1981, Intel released the CPU under the name Intel 8086, which was the first CPU to use the x86 architecture. This architecture later became the industry standard used by almost all personal computers that exist today. Furthermore, CPUs continued to be developed by increasing their speed and capabilities, as well as lowering their costs so that they could be reached by more people.

Currently, the CPU has become a very important part of a computer and there are many manufacturers that develop CPUs with different specifications. Some of the leading manufacturers in the market today include Intel, AMD, and ARM. Apart from that, CPUs have also been used in various other devices such as smart phones, tablets, and IoT (Internet of Things) devices.

CPU function

CPU (Central Processing Unit) is the core of a computer that handles all the instructions given to the computer. The CPU is responsible for executing all commands given to the computer, be it from the operating system, applications or input given by the user. In general, the CPU has several main tasks:

  1. Executes instructions given to the computer, including instructions given by the operating system, applications, and user input.
  2. Control access to memory and other devices connected to the computer, including hard drives, peripherals, and network devices.
  3. Control the flow of data in and out of the computer, including sending data to displays, printers, and other peripherals.
  4. Perform complex mathematical calculations, such as those required to run applications that require a lot of data processing.

In general, the CPU is the most important part of a computer and is responsible for running most of the processes that occur in the computer. The CPU has a high speed and can execute instructions quickly, thus enabling the computer to run applications that require a lot of data processing quickly.

Types of Basic Types of Cpu

There are several types of CPU (Central Processing Unit) available in the market, and they can be classified based on various factors, such as their architecture, clock speed, number of cores, and power consumption. Here are some of the basic types of CPUs:

How CPUs Work

Since it was first invented, the CPU (Central Processing Unit) has become a very important part of every computer. The CPU is the “brain” of the computer which handles most of the data processing performed by the computer. The following is how the CPU works:

  1. The CPU receives instructions from other devices inside the computer, such as memory or storage devices.
  2. The CPU takes these instructions and executes them using the units built into them, such as the arithmetic and logic unit (ALU) and control unit.
  3. These units are responsible for carrying out mathematical and logical operations according to the instructions given.
  4. After an instruction has finished executing, the CPU returns to step 1 to execute the next instruction.
  5. This process occurs continuously, so the CPU can handle many instructions in a short time.
  6. The CPU also has an internal cache that is used to store frequently used data, so that the CPU does not need to constantly fetch data from main memory every time it is needed. This speeds up the data processing process.
  7. CPU speed is determined by the clock speed used to control the instruction processing process. The faster the clock speed, the faster the CPU can execute instructions.

How the Operations Performed by the CPU

CPU (Central Processing Unit) is the main component of the computer which is responsible for executing the instructions given to the computer. The CPU performs a wide variety of operations, including data processing, decision making, and communicating with other components in the computer.

Some of the common operations performed by the CPU are:

  1. Execute the commands given by the operating system or running application.
  2. Add, subtract, divide and perform other mathematical operations on binary numbers stored in the computer’s memory.
  3. Access and process data stored in computer memory.
  4. Control the flow of data to and from other components in the computer, such as memory, hard drives, and other input/output devices.
  5. Make decisions based on available data and execute appropriate instructions.
  6. Manage communication with other devices in the computer, such as the motherboard, hard drives, and other input/output devices.

The CPU can also perform more complex operations, such as executing machine language code or solving problems using complex algorithms. However, these operations are usually performed by the CPU only when instructed by the operating system or running applications.

Conclusion

The central processing unit (CPU) is the core of a computer system which is responsible for carrying out all instructions given to the computer. The CPU is the most important part of the computer system because it is responsible for controlling and processing all instructions given to the computer.

The CPU consists of several parts, including registers, control unit, and arithmetic logic unit (ALU). The CPU receives input from other hardware devices, such as keyboards, mice, and hard drives, and processes them according to instructions given by software, such as the operating system or applications. The CPU is also responsible for storing the results of data processing into computer memory.
