My typical day is quite busy; it begins at 6 o’clock in the morning when I wake up. When my alarm goes off, I turn it off, get up and make my bed. Then I take a shower, brush my teeth and do my morning workout

Computer System
Computer is an electronic device that takes data as an input and processes it under the control of a set of instructions (called program) and then produces a result (output), and all the set is called as computer system.
All general-purpose computers require the following hardware components :
Memory : It is used to store data and programs.It may be temporary or permanent
e.g RAM,ROM
This is main Part of computer system, Is also known as processor and consist of three units which is as follow ,
i) Control Unit ( C U)
ii) Arithmetic logic Unit ( A L U)
iii) Main Memory unit ( M M U)

i) Control Unit ( C U) :It controls all other units in the computer. The control unit instructs the input unit, where to store the data after receiving it from the user. A control unit (CU) handles all processor control signals, control unit directs the entire computer system its also communicate with both the arithmetic logic unit (ALU) and main memory.The control Unit or CU Controls or coordinates all activities performed in a computer system.

ii) Arithmetic logic Unit ( A L U) : All calculations are performed in the Arithmetic Logic Unit (ALU) of the computer. It also does comparison and takes decision.
Arithmetic operation comprises of (Addition, subtraction, division, multiplication) and the logical unit carries out the operation such (AND, OR, Equal, less than, greater then).
Data is transferred to ALU from storage unit when required. Whenever calculations are required, the control unit transfers the data from storage unit to ALU once the computations are done, the results are transferred to the storage unit by the control unit and then it is send to the output unit for displaying results.
iii) Main Memory unit ( M M U) : The main memory unit is used for storage of the copy of the main software program that controls the general operation of the computer and temporary storage of a copy of application program instruction, to be received by CPU for interpretation and processing or execution.
