The main unit of digital computer is called CPU (central is called cpu (central processing unit) The unit Cpu have following main units. Memory Unit (M-U) The basic function of computer memory is to store data (information) for further processing. Memory unit is volatile (perishable). Therefore all the programs stored in. it are lost if computer power is switched off referred as primary memory. The unit of memory is byte. Its higher term kilo byte (KB), mega byte (MB), giga byte (GB). Its also called a temporary memory. Control Unit (C-U) Control unit like a manager of bank. Control unit is a manager of computer. Its manage all activities of ALU & MU unit like receive instructions from input device & send these instructions to ALU for processing. Its also responsible to controls the execution of program. Arithmetic & Logic Unit (A-L-U) Its perform actual processing of data which include both types arithmetically and logically operations. We can also say micro processor.
