Study Notes

Components of a Computer System

A computer system consists of input devices, central processing unit (CPU), primary memory, arithmetic logic unit (ALU), control unit (CU), and output devices.
The CPU is the brain of the computer and is commonly referred to as the processor.
The CPU is made up of electronic circuitry that carries out the actual processing and is usually placed on one or more microchips called integrated circuits (IC).

Central Processing Unit (CPU)

The CPU is the electronic circuitry of a computer that carries out the actual processing and is usually referred to as the processor.
The CPU is physically placed on one or more microchips called integrated circuits (IC) that comprise semiconductor materials.

File Management

File management involves the creation, updation, deletion, and protection of files in the secondary memory.
The operating system manages secondary memory, while memory management system handles the main memory of a computer system.
Protection is a crucial function of an operating system, as multiple users can access and use a computer system.

Device Management

The operating system manages heterogeneous devices that are interdependent and interacts with the device driver and related software for a particular device.
The operating system must provide options for configuring a particular device, so that it may be used by an end user or some other device.
Security measures are necessary to restrict access to different devices to authorized users, software, and other hardware only.

Computer System

A computing device, also referred to as a computer, processes input data as per given instructions to generate desired output.
A computer system has four physical components: CPU, primary memory, input device, and output devices.
These components are referred to as the hardware of a computer.

Hardware

Hardware refers to the physical components of a computer system that can be seen and touched.
Examples of hardware include RAM, keyboard, printer, monitor, and CPU.

Software

Software is a set of instructions and data that makes hardware functional to complete a desired task.
The sole purpose of software is to make the computer hardware useful and operational.
Software acts as an interface between human users and hardware.

Types of Software

Software can be broadly classified into three categories: system software, programming tools, and application software.
System software provides the basic functionality to operate a computer by interacting directly with its constituent hardware.
System software knows how to operate and use different hardware components of a computer and provides services directly to the end user or to some other software.
