Basic Parts Of Computer
Posted By admin On 23.09.19The CPU, or central processing unit, provides most of a computer's intelligence. CPUs perform arithmetic calculations, compare data and move information from one memory location to another under the direction of a program. Computer programs are instructions given to the CPU to perform a task.
C.p.u: It stands for central processing unit, which is called brain of the computer. It handles all processing functions of data like logical, mathematical function. Knowing what are the parts to build a computer is one of most valuable hardware knowledge you can have. Learn it all today with our complete computer parts list (with pictures).
CPUs can execute program instructions one after another or they can jump from one part of the program to another based upon the results of previous calculations. CPUs rely on memory locations called registers to hold data to be processed or program instructions. In addition, some CPUs have a special cache of high-speed memory used to hold a copy of frequently used data from the computer's main memory close at hand for fast access.
Central Processing Unit (CPU)The CPU is the 'brains' of the computer. The central processing unit provides the calculations and manipulation of data sent from the user.
Each time the user clicks a key, executes an application or browses the Web, the CPU reads the code involved and returns the response to the user. The CPU works closely with memory, which is the component that sends stored data to the unit.Random Access Memory (RAM)RAM is variable in a computer. Older computers had only a few dozen megabytes of RAM installed. When personal computers became popular in the 1990s, computers had 32 megabytes of memory. Motherboards and software now require at least one gigabyte to function. RAM contains the information during the time the computer is on.
After the machine is turned off, the information in RAM is lost. Hard DriveUnlike RAM, the hard drive stores data even after the machine is turned off.
A hard drive is the storage unit for the machine. Saved documents and applications are stored on the hard drive using magnetism.

The hard drive is made up of small platters with a moving head. The platters spin as the head moves back and forth to retrieve and store data.Video CardThe video card provides the image seen on the monitor. The video card is attached to a monitor using a VGA cable. Some video cards have two monitor connections. This allows the user to attach two monitors to the computer, so the desktop can be spread across both monitors for better usability.MotherboardEach component is attached to the motherboard.
The motherboard receives power from the computer's power supply. The motherboard allows all the components to communicate, including the CPU.

The motherboard also contains controllers, which are circuits that help the operating system work with hardware such as the hard drive.
