To promote Digital Education in rural India
We denounce with righteous indignation and dislike men who we are to beguiled demoralized by the charms of pleasures that moment, so we blinded desires, that they indignation.

This is the era of Digital Transformation where every legacy oragnizations are transforming their systems into Digital System. Digital Transformation boost organization productivity and reduce human efforts by automation. As, Computer is important part of Digital Transformation so our volunteers started various intiatives to educate everyone Digitally. In this context, we are publish some blogs on Computer System.
In this blog we will learn about :
A computer is an electronic device which accepts data as input, performs operations on the data based on the instructions stored in the memory and produces output. General representation of a computer is as shown below:
The architecture or structure of a computer is as shown below:
The essential hardware components of a computer are:
1) CPU (Central Processing Unit)
2) Memory
3) I/O (Input/Output) Devices
Central Processing Unit (CPU): The CPU is the core hardware component of a computer. It is responsible for executing instructions such as arithmetic calculations, comparisons among data and movement of data inside the system.
Arithmetic Logical Unit: The ALU performs arithmetic and logical operations on the data based on the instructions stored in the memory.
Control Unit: The Control Unit (CU) coordinates the system components, like transfer of data between the components, timing etc.
There are two types of memory in the computer system. They are: 1) Main memory or Primary memory and 2) Auxiliary memory or Secondary memory.
Auxiliary memory: When we turn off the computer, our programs and data remain in the secondary storage, ready for the next time we need them.
The motherboard, or mainboard, of a PC is a large circuit board that is home to many of the most essential parts of the computer like: microprocessor, chipset, cache, memory sockets, bus, parallel and serial ports, mouse and keyboard connectors, hard disk and floppy disk sockets etc.
Microprocessor or Processor or Central Processing Unit is the heart of every computer. I Whenever a user executes a word processor, a computer game, a browser or any other software program, the CPU performs hundreds or even thousands of instructions. The microprocessor is a piece of electronic circuitry that uses digital logic to perform the instructions of the software.
The Random Access Memory (RAM) is used to store data, instructions (programs) which are accessed by the CPU for execution. RAM is also known as main memory or primary memory. The data or instructions stored on the RAM can be accessed at random. Hence the name Random Access. RAM is known as volatile memory means, the data or information stored on the RAM is wiped out once the computer is turned off or the power goes off.
Read Only Memory is a non-volatile memory in the computer.
Benefits of Computer Education
Computer System knowledge helps you to develop smart solution for complex problem
Computer System helps us to store data easily and share around a globe in just a few seconds of span
Easy to Sell items and connect with Customers
Computer Science helping human being in all the Domains ( Aerospace, CIVIL, Aviation, E Commerce, BFSI etc)
Hope you learned about Computer System, their parts and key benefits. Still if you face difficulty then feel free to contact us on info@ydrfoundation.in so our volunteers can help you
