Hardware and Software Components of Computer

Presentation is about the hardware and software components of computer, prepared for the B.Ed. Semester II, students of University of Lucknow.

1. HARDWARE AND SOFTWARE COMPONENTS OF COMPUTER AND THEIR EDUCATIONAL IMPLICATIONS Dr. Roma Smart Joseph Teacher Educator I Lucknow I India

2. Hardware Components: Hardware refers to any physical or tangible elements of Computer. There are four main Computer hardware components- Input devices Output Devices Processing devices Memory ( storage) devices

3. 1.Input Devices : Input devices are used to give instructions to the computer. Input devices act as a medium for sending data to a computer to be used and controlled by the user. Most widely known examples are: Keyboard Mouse Joystick etc.

4. 2. Output devices: An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system which converts the electronically generated information into human-readable form. Monitor Printer speaker etc.

5. 3. Processing Devices Data received from an input device, first go through an intermediate stage before it is sent to an output device. Processing is the intermediate stage where raw data is transformed into meaningful output information for the user. An example of a processing device is the central processing unit (CPU), which is a set of electronic circuitry that processes and executes instructions. 

6. 4. Memory (storage) devices Memory devices in computer are capable of storing information temporarily or permanently. There are two types of memory; Primary and Secondary. Primary memory refers to RAM (random access memory), which is used to store instructions and data temporarily before and after they are processed.

7. 4. Memory (storage) devices RAM is volatile, which simply means it only retains information when The computer is turned on and is cleared once the computer turns off.  Secondary memory refers to any external storage media. Secondary memory is non-volatile, which means that information can be stored long-term. The most common example of an external secondary memory device is the USB flash drive. 

8. Software Software is a set of programs written in different languages. These languages may be high level languages, machine level language or assembly languages. For example, MS word, MS PowerPoint, MS Excel etc.

9. Computers in Education Storage of information. Quick data processing. Audio-visual aids in teaching. Better presentation of information. Access to the Internet. Quick communication between students, teachers and parents.

10. 1.Computers are a brilliant aid in teaching. 2.Computers have given impetus to distance education. 3.Computer software help better presentation of information. IMPORTANCE

11. 4.Computers enable access to the Internet which has information on literally everything. 5.Computer, hard drives and storage devices are an excellent way to store data.
