Which component of the computer gives data and instructions for processing?
View Discussion Improve Article Save Article View Discussion Improve Article Save Article Computer: A computer is a combination of hardware and software resources which integrate together and provides
various functionalities to the user. Hardware are the physical components of a computer like the processor, memory devices, monitor, keyboard etc. while software is the set of programs or instructions that are required by the hardware resources to function properly. Digital Computer: A digital computer can be defined as a programmable machine which reads the binary data passed as instructions, processes this binary data, and displays a calculated digital output. Therefore, Digital computers are those that work on the digital data. Details of Functional Components of a Digital Computer
Interconnection between Functional Components A computer consists of input unit that takes input, a CPU that processes the input and an output unit that produces output. All these devices communicate with each other through a common bus. A bus is a transmission path, made of a set of conducting wires over which data or information in the form of electric signals, is passed from one component to another in a computer. The bus can be of three types – Address bus, Data bus and Control Bus. Following figure shows the connection of various functional components: The address bus carries the address location of the data or instruction. The data bus carries data from one component to another and the control bus carries the control signals. The system bus is the common communication path that carries signals to/from CPU, main memory and input/output
devices. The input/output devices communicate with the system bus through the controller circuit which helps in managing various input/output devices attached to the computer. Which part of the computer processes instructions and data?Central processing unit is the main part of the computer hardware that actually processes data according to instructions it receives.
What components of a computer are important for processing data?The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want. The central processing unit executes computer instructions that are specified in the program.
