2. OUTLINE Types of Computer(On the basis of mechanism) Hardware And Software

3. Types Of Computer Three types on the basis of mechanism: Analogue Computer Digital Computer Hybrid Computer

4. Analogue Computer Analog computers are specifically designed to process analog data. It is a type of continuous data that continually changes and does not have discrete values. These types of computers are being used when the users are not familiar with the exact values like temperature, speed, current, and pressure. Examples of analog computers are the mercury thermometer (used to determine the temperature of body, liquid, and vapor) and speedometer (Used for measuring speed)

5. Digital Computer These computers are designed in such a way that they can easily perform calculations and logical operations at high speed. Such a type of computer takes up raw data as input and processes it with programs stored in its memory to produce the final output. A Digital computer only understands the binary input 0 and 1, so the raw input data is converted to 0 and 1 by the computer and further processed by the computer to give the result or final output. Present-day modern electronic gadgets such as laptops, and desktops including smartphones are digital computers.

6. Hybrid Computer These computers combine the features of analog and digital computers. They use analog-to-digital and digital-to-analog converters to process both continuous and discrete data. Example: Medical diagnostic equipment, such as an electrocardiograph (ECG), that converts analog signals from the body into digital data for processing.

7. Components of Computer

8. Computer Hardware Hardware refers to the physical components of a computer. Computer Hardware is any part of the computer that we can touch these parts. These are the primary electronic devices used to build up the computer. Examples of hardware in a computer are the Processor, Memory Devices, Monitor, Printer, Keyboard, Mouse, and Central Processing Unit.

9. Types of Computer Hardware Input Devices Output Devices Storage Devices Internal Component

10. Input Devices Input Devices are those devices through which a user enters data and information into the Computer or simply, User interacts with the Computer. Examples of Input Devices are Keyboard, Mouse, Scanner, etc.

11. Output Devices Output Devices are devices that are used to show the result of the task performed by the user. Examples of Output Devices are Monitors, Printers, Speakers, etc.

12. Storage Devices Storage Devices are devices that are used for storing data and they are also known as Secondary Storage Data. Examples of Storage Devices are CDs, DVDs, Hard Disk, etc.

13. Internal Component Internal Components consists of important hardware devices present in the System. Examples of Internal Components are the CPU, Motherboard, etc.

14. Computer Software Software is a collection of instructions, procedures, and documentation that performs different tasks on a computer system. we can say also Computer Software is a programming code executed on a computer processor. The code can be machine-level code or code written for an operating system. Examples of software are MS- Word, Excel, PowerPoint, Google Chrome, Photoshop, MySQL, etc. Types of Computer Software System Software Application Software

15. System Software System Software is a component of Computer Software that directly operates with Computer Hardware which has the work to control the Computer’s Internal Functioning and also takes responsibility for controlling Hardware Devices such as Printers, Storage Devices, etc. System Software are as follows: Operating systems Language processors Device Drivers

16. Application Software Application Software are the software that works the basic operations of the computer. It performs a specific task for users. Application Software basically includes Word Processors, Spreadsheets, etc. Types of Application software include General Purpose Software, Customized Software, etc.
