Function of ALU (Arithmetic Logic Unit in Computer)

Function of ALU (Arithmetic Logic Unit in Computer) Points : function of alu (arithmetic logic unit in computer) The ALU (Arithmetic Logic Unit): When the control unit encounters and instruction that involves arithmetic or logic operations, it passes control to the second component of CPU, the arithmetic/Logic unit (ALU). Arithmetic operations are as you might except, the fundamental math operations like addition, subtraction, multiplication and division.

1.Computer can accept and operate alphabetic data.Calculator can not accept alphabetic data.
2.Computer has large memory for storing programs hind data.Calculator has small memory.

Parts of CPU

Parts of CPU Points : Parts of CPU, Control Unit (CU), Arithmetic and Logic Unit (ALU), Registers, Memory Unit (MU) Parts of CPU: i. Control Unit (CU)
ii. Arithmetic and Logic Unit (ALU)
iii. Registers
iv. Memory Unit (MU)

Difference Between RAM and ROM

Difference Between RAM and ROM Points : difference between ram and rom, ram vs rom
Difference Between RAM and ROM
RAM
ROM
1.RAM is larger and busier of the two. When program and data are joined into the computer they are put in RAM.ROM holds the built-in operating system, basic input output system (BIOS) and utility programs responsible for carrying out computers basic functions.
2.As the name implies, the memory location in RAM can be accessed randomly.These are normally accessed automatically when the computer is turned on.

Memory Unit and its two major types

Memory Unit and its two major types Points : define memory unit and its two major types, read only memory (rom), random access memory (ram) Memory Unit Memory unit is the place where the computer program and data re stored during processing. It is the area, through which all the data which is input into or output of the CPU mist pass. ft is monitored by OU which keeps track of every thing in the storage. It is a random access device, which consists of thousands upon thousands of storage locations, each of which can be directly reached by the CU. Each storage location is distinguished by the address.

It is divided into two parts.

CPU and its different units

CPU and its different units Points : cpu and its different units, central processing unit (cpu), ? arithmetic and logic unit (alu), centro unit (cu), memory unit (mu), Central Processing Unit (CPU) Central Processing Unit (CPU) is the brain of computer system. We use CPU to control all input and output connections inside arid outside of computer to produce correct answers for the user. it controls and supervises all the units in a computer. It takes information from the input unit and from the memory and uses it according to the instructions already given to the computer. From functional point of view CPU consists of three parts.

Major Function of Input and Output Devices

Major Function of Input and Output Devices Points : major function of input and output devices Major Function of Input Device
  • These are physical equipments that read or translate data consisting of alphabets, number or other symbols into electronic impulses, which can be understood by the computer.
  • The purpose of input devices is to pass information into the memory unit of the CPU.
