What is Computer
An device for storing and process knowledge, usually in binary type, in keeping with directions given to that in an exceedingly variable program. someone WHO makes calculations, particularly with a calculator.
Four Basic components of a Computer
CPU
The CPU, or central process unit, provides most of a computer's intelligence. CPUs perform arithmetic calculations, compare knowledge and move info from one memory location to a differe
nt below the direction of a program. laptop programs square measure directions given to the processor to perform a task. CPUs will execute program directions one once another or they'll jump from one a part of the program to a different primarily based upon the results of previous calculations. CPUs trust memory locations known as registers to carry knowledge to be processed or program directions. additionally, some CPUs have a special cache of high-speed memory accustomed hold a replica of oft used knowledge from the computer's main memory shut at hand for quick access.
Motherboard
By itself, the processor isn't any additional helpful than a automotive engine while not a chassis, transmission or wheels. The motherboard provides the route for the transfer of knowledge throughout the pc. The computer's main memory or system RAM, network interfaces, USB ports, video inputs, device interfaces, BIOS and system clock square measure either engineered into or connected to the motherboard by a slot .
Input Devices
Your Computer gets info to method from many sources. Input devices like your keyboard, mouse, electronic device and bit pad feed info and directions to the applications running on your laptop. different sources of information embody arduous disks, CD-ROM, DVD-ROM and USB thumb drives. info conjointly streams into a laptop from network connections just like the web.
Output Devices
Output devices square measure required to quickly or for good show, broadcast or record the work done by your laptop. laptop speakers and monitors square measure output devices. several computers have storage devices like arduous drives, SSD drives, thumb drives or CD burners which offer a additional permanent style of knowledge output and storage. different output devices like printers and projectors square measure connected the pc through ports.
