Easy revision notes for RGPV exam
Computer is an electronic device used to accept data, process it and produce meaningful information. Main characteristics are high speed, accuracy, automation, large storage capacity and reliability.
Computers are classified on working principle as analog, digital and hybrid computers. Based on size, computers are micro, mini, mainframe and super computers.
Computer organization describes the functional units of a computer and their interaction. Main units are input unit, CPU, memory unit and output unit.
CPU is called the brain of computer. It performs arithmetic operations, logical operations and controls all system activities with the help of ALU, CU and registers.
Registers are small high-speed storage locations inside CPU. Examples are accumulator, program counter, instruction register and memory address register.
Bus is a communication pathway connecting computer components. Main types are data bus, address bus and control bus.
Memory stores data and instructions. Primary memory includes RAM and ROM. Secondary memory includes hard disk, CD/DVD and pen drive.
Input devices enter data into computer, such as keyboard, mouse and scanner. Output devices show processed results, such as monitor, printer and speaker.
Software is a collection of programs and instructions. System software controls hardware, while application software performs specific user tasks.
Operating system is system software that manages hardware and software resources. It performs process, memory, file, device and security management.
MS Word is used for document creation, MS PowerPoint is used for presentations, and MS Excel is used for calculations, charts, functions and formulas.
Computers are used in e-business, healthcare, bio-informatics, remote sensing, GIS, meteorology, gaming, multimedia and animation.
