ICT IGCSE Theory – Revision Presentation Chapter 1: Types and components of computer 1.1 Hardware and Software. Define hardware as consisting of physical components of a computer system. Identify internal hardware devices (e.g. Processor, motherboards, random access memory (RAM), read-only memory (ROM), video cards, sound cards and internal hard disk drives. Hardware and software form the main parts of any computing device. The physical parts of the computer make up the hardware, while the apps or programs is the software of any computing device. Furthermore, the hardware is often referred to as the machinery of. System software operates directly on hardware devices of computer. It provides a platform to run an application. It provides and supports user functionality. Examples of system software include operating systems such as Windows, Linux, Unix, etc. Take a peak into the relationship between software and the hardware it controls.Start learning at Stay in touch with us!. on Twitter https:/.

Hardware and software work together in digital devices and systems to provide computerized functionality. Hardware includes the physical components, such as the motherboard, chips, memory, and hard drives, while software includes the programs. Though both are most often associated with computers, software also runs on other hardware, such as cellular phones, personal digital assistants (PDAs), Global Positioning Satellite (GPS) units, medical equipment, and air traffic control systems. Modern cash registers are also computerized with software to better organize sales-related issues like inventory, tax, and coupon discounts.

Hardware and software are constantly improving in a kind of leapfrog fashion. The former is most often the bottleneck when it comes to data transfer speeds, or how fast a program can work. Therefore, as hardware improves, it becomes capable of running more robust programs. Old hardware from just ten years ago may not run current software, as the programs might be designed to take advantage of hardware in ways that older pieces of equipment cannot support.

For this reason, when shopping for software, the buyer should check the specifications for recommended minimal hardware requirements. The central processing unit (CPU) of a computer is nearly always mentioned, as this hardware is responsible for the overall speed of the computer, generally speaking. The amount of Random Access Memory (RAM) is another factor, and graphics capability or video card requirements might also be mentioned.

If you would like to purchase software but are not sure what hardware you have, most operating systems have a built-in program for displaying hardware and software system information. In Windows XP, navigate by clicking the Start button, then All Programs, Accessories, System Tools, and System Information. You may want to print the initial system summary page, then click on the appropriate heading in the tree to the left to see new information displayed on the right. For example, click on “Components” then “Display” to see details about the video card in your computer.

Components of Computer- Hardware and Software

There are many components of computer such as monitor, printer, ms-office, scanner etc. But generally it is categorized in two types such as hardware and software.

So, Basically there are two components of computer:-

1. Hardware
2. Software

1. Hardware:-
   • The physicalpart of computer is known as hardware.
   • We can touch and seethe hardware.
   • The visible partsof computer is known as hardware.

ex;- Keyboard, mouse, CPU, monitor, printer etc

There are three types of hardware

1. 1. Input device
   2. Processing device
   3. Output device
2. 1. 1. Input device:- It help the users to feed the data into computer.By using input Device a user can enter data into computer.

Ex: Mouse, Keyboard, OMR, OCR etc

1. 1. 1. Processing device:-It Perform all internal task of the computer according to input instruction.It perform all arithmetical and logical operation.

Ex:- CPU (Central Processing Unit)

1. 1. 1. Output Device:-It help the user to display the result after processing.

Ex:- Monitor, Printer etc

1. 1. 2. Software:-
         • The logical partof computer software is known as software .
         • We can’t touch and seethe software
         • The invisible parts of computer is known as software

There are three types of software:-

1. 1. • System Software
      • Application software
      • Utility software
   2. 1. • System software:-
           • The software which is used by the system is known as system software
           • It coordinates the internal operation of the computer.

There are two types of system software

1. 1. • Operating System
      • Language Processor
   2. 1. • Operating system:-
           • It is a type of system software which interface between user and hardware.
           • It coordinates the internal operation of the computer.

For example- Linux, Windows,Unix, DOS etc

1. 1. • Language processor:-
        • It is a type of system software which is used in programming language to convert source code to object code object code to source code.
        • It work as an intermediator or translator.

There are three types of language processor

1. 1. • Assembler
      • Compiler
      • Interpreter

1. 1. • Assembler:-It is a language processor which is used in low level language or assembly language to convert source code to object code or object code to source code.
      • compiler:-It is a language processor which is used in high level language to convert source code to object code or object code to source code. It compiles or check errors whole content at a time .
      • Interpreter:-It is a language processor which also used in high level language to convert source code to object code or object code to source code but it detect the error line by line.

1. 1. • Application software:-
        • The software which is used by the user is known as application software.
        • It is a general purpose software which helps the user to perform any general task quickly.

There are two types of application software:-

1. 1. • Custom Written Software
      • Packaged Software
   2. 1. • Custom Written Software:-
           • The software which is made by according to user choice is known as custom written software
           • It is a specific purpose software which is used in special area.

For ex: Banking Software, Hotel software, Institute software, Medical software etc

Hardware And Software List

1. 1. • Packaged Software:-
        • The readymade software is known as packaged software.
        • It is a general purpose software which is use to accomplish different types of task.
