When buying a computer device normally someone would see the specifications first. We also often hear the term Pentium and some specifications such as quad-core Intel i7 3.5 GHz, and so forth. This term refers to the speed of a computer processor or called by the CPU.You are already familiar with the term CPU may have a clear idea of
understanding and the CPU function, but for those who do not know,
it's good to learn it.understanding CPUCPU stands for Central Processing Unit is the hardware component of the hardware or the main data processor in a computer. CPU can be referred to as the computer brain of the CPU organizes all
activities and running all applications or software programs included in
it.Whatever it all matters relating to the process of the computer system either a trivial process will always be set by the CPU. For
example, when you press the letter "H" on the keyboard while typing,
the letter "H" will appear on the screen, the CPU was the one who
allowed it to happen. Thus, in the absence of a CPU in a computer, the computer will not be
able to do anything or the computer can not run the program.CPU also technically more commonly referred to as the processor,
therefore the time to read and identify the actual specifications for
the processor then you're reading the specifications of the CPU of a
device.components CPUA CPU at least have a "processor" or a chip that is embedded in functioning in the process of computer calculations. However, rapid technological developments also allows a CPU has more than processor or also known as the "processor core".The
terms we often hear today comes from the CPU technological
developments, for example technology "dual core" in which a CPU has two
processing cores, or quad core, which has four processing cores. A sophisticated CPU even have the technology with six (hexa-core) or eight processing cores (octo core).
Not only that, a sophisticated computer server can have more than one CPU with many processing cores inside.
CPU functions
As a major component in a computer, the CPU has several important functions. Among these functions are:
1. Fetching
Fetching is a term used in computer science and is understood as a process of extraction or retrieval. In a computer, the data is stored in the hard disk on CPUs with an address.
Likened data within the processor or CPU arranged in a set of addresses and when a program is executed the CPU will take data from the address stored in the component.
2. Decoding
In a system CPU, a program to be executed or to be executed, shall be in accordance with the code of instructions that will be translated so that the CPU can recognize it in binary instruction code. It can be concluded that the decoding is a process of translating a program into a language understood by the CPU.
Decoding occurs in the CPU and all the programs running on the computer device to go through the process of decoding first.
3. Executing
When a program is executed then the CPU will execute the program. The point is that the CPU will do the one thing that is doing the calculations or calculations using a component therein called the ALU or Arithmetical Logical Unit.
Component ALU itself is responsible for all the mathematical calculations and logic in the computer. Besides the function execution of a CPU is also meant as a process of moving data from one storage device to the other memory devices.
4. Storing
Storing or storing data is one of the other functions of the CPU. When someone uses a computer then he needs a device to keep it provisionally or permanently.If someone needs data quickly and temporarily save it then the CPU will store it in RAM while the data is permanently stored in the hard disk will be entered into. Both functions are performed and controlled entirely by the CPU.
To run these functions rely on the CPU not only the processor but also involves several other devices including hard disk, motherboard, RAM, floppy drive, sound card, USB port, VGA Card and so forth. All of the parts are arranged in such a manner and are connected to each other. The faster the CPU is working, the better the performance.
CPU speed is measured in Hertz, which means one operation per second, and is usually written in units of GHz or Giga hertz. 1 GHz CPU speed is defined as one million in performing operations in a computer. Do you now understand what is meant CPU in a computer and their functions?
