functions of cpu
cpu consists of ALU, Control unit assisted by a set of registers. control unit sends control signal to synchronize the flow of information between the different units of the computer and helps to fetch, decode and execute the instructions from memory. alu performs all the arithmetic and logical operations in the instructions. registers help in quick transfer of data to and from cpu.

The part of the computer that does the calculations?
The part of the computer that performs calculations is the Central Processing Unit (CPU). The CPU is often referred to as the "brain" of the computer because it carries out instructions from programs, processes data, and performs arithmetic and logical operations. Specifically, the Arithmetic Logic Unit (ALU), a component within the CPU, is responsible for carrying out the actual calculations and logical decisions.
What are the five basic operations performed by any computer system?
Process ManagementMemory ManagementInput/Output ManagementFile ManagementInterface (Menus Pointers ect)
How many amputations performed in the United States are due to circulatory complications of diabetes?
More than 90% of amputations performed in the United States are due to circulatory complications of diabetes. Sixty to eighty percent of these operations involve the legs
Do cell phone contain a CPU?
A cellphone always contain a small CPU
Definition of manual data processing?
Manual data processing takes place when all the functions and operations are performed by personnel. The data is processed physically by humans without the help of algorithms.
What is logic unit in CPU?
It performs arithmetic and logic operations within the microprocessor.
The four operations performed by a computer include?
The four operations performed by a computer include processing, accepting input, output and storage. All of the operations of a computer occur in the CPU.
What are the founction of the registers found in the CPU?
The registers are inside the CPU and await tasks you send to your compter from, The CPU picks these up and the registers then get to work to process them to give you an outcome. General Purpose Register (intel) gave these worktables names: AX, BX, CX & DX.
What tasks are carried out by CPU?
cpu controls the logic and arithmetic operations and cpu is the brain of the computer
Are arithmetic and logical operations carried out inside the CPU?
No, in on the MR
What performs the arithmetic computation and logic operations in the CPU?
ALU
Does the DIMM perform simple math for the CPU?
No. The RAM (in the DIMM) is a storage area. The CPU performs mathematical operations.
What is the difference between the arithmetic operations and logical operations which are performed by the CPU?
An arithmetic operation is dealing with data in a computational manner, adding subtracting, etc A logical operation would normally be regarded a a comparison and decision, though one school of though would include the literally 'logical operations' such as NOT, OR, AND, etc.
What directs the flow of data through the CPU and other devices?
which part of th CPU would proform arithmetic operations
What component performs mathematical operations in computers?
Arithmetic logic unit in the cpu
Describe how cpu work?
The CPU or central processing unit of a computer is the brain. It directs the operations of the computer and gives instructions to the other components.
Where operations performed?
theatre
