What is CPU All About

We’ll talk about the processor device that allows a job processing system. Also Abbreviationfinder called CPU(Central Processing Unit-central processing unit) and is in effect the brain of the computer, as it executes instructions and coordinates the work of all devices.

About the CPU

The CPU consists of a control unit (CU, that manages and executes the instructions to be processed), the ALU (Arithmetic Logic Unit, which performs arithmetic and logical), and registers (fast memories saved states, memory addresses, checks for errors and process data information).

To optimize your work, the process must synchronize other devices: every change of state is punctuated by a synchronous signal called Clock.

Typically, the CPU processes in three steps: acquires the instruction from memory, decodes it and finally the run, returning the result.

The main task of a CPU is then run programs, which is a series of instructions. Each processor has a set of native instructions. This can be reduced (RISC) or large (CISC). When it processes a portion of the program, then uses its own set and software instructions, saving the remaining and the data in a fast memory called cache.

The power of a processor is the speed in which it processes and the amount of bits that can run concurrently.

The speed is measured in billions of cycles per second (Gigahertz GHz), while the amount is directly related to the size of the bus that connects it to the NorthBridge of the motherboard (FBS) and that provides data to be processed: 32 or 64 Bits are used currently to FBS.

What is CPU All About 2

The CPUs can contain one or more processing cores working simultaneously, thus allowing multiple statements. The most common are the dual core CPU, quad core and octo core, respectively with 2, 4 and 8 cores.

The processor installed on the motherboard by inserting into a socket. The most common are PGA pin grid arrays (where the pins are present on the underside of the CPU) or LGA (with pins directly into the socket).

What is CPU All About 3

The most important producers of processors are Intel and AMD. Using a lot of energy to run jobs, CPUs tend to overheat.
Being one of the most expensive computer devices, is so well cared for, avoiding overheating thanks to a quality heat sink and applying thermal paste.
