Ammon – CPU types
The central processing unit is the basic component of any digital computer system, and it consists of three components: the main memory, the control unit, and the arithmetic logic unit. It is also the heart of a physical computer system; This is because it is connected to peripheral equipment, such as input and output units, in addition to storage units, and the central processing unit is located in modern computers on an integrated circuit chip; It is called a microprocessor. It is possible to divide the types of CPU into 3 types, namely:
Single core CPU
Single-core CPU is the oldest type of CPU available, which is used in the majority of laptops and desktops, and this type can only execute one command at a time, and it is an inefficient type in multitasking, and it is known to decrease its performance significantly if it works user on more than one application.
And in the case of starting one command, it must wait for its completion before starting to execute another command, but in the event that several operations are started together, the performance of the computer decreases significantly, and the work of the single-core CPU depends on its speed by measuring its strength.
Dual core CPU
This type of CPU consists of two powerful cores, and performs specific functions, such as: the dual CPU that works as one unit, and unlike the single-core CPU, the processor must be shifted back and forth within a set of variable data streams, and if one task is executed , or more, the dual-core CPU effectively handles multitasking.
To take advantage of this type of CPU very effectively; Running programs and the operating system must have a token; Called its built-in concurrent multi-threading technology, the dual-core CPU is faster than the single-core CPU, but not as powerful as the quad-core CPU.
Multi-core CPU
Quad core CPU is an upgraded form of CPU, which is a type designed with four cores on one CPU, same as dual core CPU.
which divides the work between the cores; Quad core CPU performs multiple tasks very efficiently, and this type of CPU is used by people who work on many different programs at the same time like gamers.
CPU components
The CPU consists of three main components, which are as follows:
storage unit
The storage unit stores data, instructions necessary for processing, and the results of intermediate processing, in addition to storing the final processing results before they are issued to the output units. It is also called the internal storage unit, main memory, basic storage, or random access memory. , and the capacity of the computer, as well as the primary memory, and the secondary memory are two types of memory in the computer.
Control unit
This unit controls the operations of the various parts of the computer; But it does not perform any actual data processing, and it controls the transfer of data and instructions between other parts of the computer, in addition to managing and coordinating the various parts of the computer. data, or results from memory.
arithmetic logic unit
The arithmetic logic unit in the CPU consists of two parts: the arithmetic section that performs arithmetic operations such as addition, subtraction, multiplication, and division, in addition to complex operations through repeated use of arithmetic operations, and the other section is the logic section that performs logical operations such as data comparison, selection, matching, and merging.
