Classification of Computers ; Computers Impact on Society
- 3. What is Computer ? Modern computers are electronic devices used for a variety of purposes ranging from browsing the web, writing documents, editing videos, creating applications, playing video games, etc. An electronic device which is used for sorting and processing data and calculating different types of math.

- 5. Types of Computers Digital Mini Computer Micro Computer Mainframe Computer Super Computer Analog Hybrid Types of Computer
- 6. Digital Computer is a machine or a device that helps to process any kind of information. These are the devices through which we provide some input and get the output within a fraction of seconds. The operations that are conducted internally in the device happens using the binary number system since the computer understands only digits 0’s and 1’s. Digital Computer
- 7. The main three components of digital computer are: Input : The user gives a set of input data. Processing : The input data is processed by well defined and finite sequence of steps. Output: Some data available from the processing step are output to the user.
- 8. One of the main advantages in the use of digital computers is that any desired level of accuracy is possible to achieve, more reliable in case of result than analog ones. The main disadvantage is their high cost, even after regular reductions in price and the complexity in programming.
- 9. Different types of Digital Computer Based on the size and type of the device, these digital computers are classified into four categories. Microcomputer Minicomputer Mainframe computer Supercomputer
- 10. A Microcomputer is not really expensive and it comes with a microprocessor as its Central processing unit and input/output devices. These computers are generally called personal computers and few of the examples are IBM pc, Apple, Dell. Microcomputer

- 12. Minicomputers are known as mid-range computers that contain one or more processors. They support multiprocessing which means these multiple processors share the same computer memory and other required peripheral devices to perform the given task. Minicomputers are generally used for processing transactions, file handling, managing database. Minicomputers
- 13. Mini computers
- 14. Mainframe computers are generally large size computers mainly used for storing large amounts of data and processing. It is known for a high level of reliability. These machines are used by an organization which requires crucial application such as census, customer statistics for large calculation which requires a high volume of data processing. Mainframe computers
- 16. Supercomputers are very expensive and the world’s fastest computers available. These computers have thousands of processors that perform trillions of calculations per second and hence the fastest known ever. Supercomputers are used extensively in enterprises and organizations that require massive calculations. Supercomputer
- 17. Super computer
- 18. Analog computers are mainly based on voltages and current with continuous electrical signals and display the output continuously. These computers store the data and perform calculations quite differently than digital computers which make use of symbolic representation. These are generally slower in speed compared to digital computers. Some of the examples are thermometer. Analog Computers
- 19. Hybrid computers are a special purpose computer that has a combination of both Analog and digital computers. They are digital computer which accepts Analog signals and converts them to digital form. These are generally used for scientific applications, airplanes, and hospitals. Some of the examples include electrocardiogram machine, ultrasound machine, monitoring machine. Hybrid computer
- 20. Hardware
- 21. Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard
- 22. Software
- 23. Software is a set of instructions, data or programs used to operate computers and execute specific tasks. Opposite of hardware, which describes the physical aspects of a computer, software is a generic term used to refer to applications, scripts and programs that run on a device. Software can be thought of as the variable part of a computer, and hardware the invariable part.
- 25. Computer’s Impact on Society Computers are commonly used in many areas. It is an important utility for people, especially those who run organizations, industry, etc. In today’s world almost everything you know runs or made by computers. Cars and jets were designed on computers, traffic signals are run by computers, most medical equipment use computers and space exploration was started with computers.
- 26. The Major Impacts are: On Education On Business On Environment On Health
- 27. The Impact on Education Education sector is impacted by computers very much. Computer has huge benefits and uses to the education sector. Some of these are: Computer can store huge and organized information It enhances creativity & thinking skills. Provides efficient & better use of IT Technology. Proves beneficial for career aspiration.
- 28. Gives instant information on any topic in just a single click, & many more. Improves research work & helps in communicating with different education providers. Quick processing of data Calculate huge number of mathematical equations and for a long time Quick Communication & Correspondence Audio visual learning is possible
- 29. The Impact on Business Computers impacted many items in today’s business world area too. Business uses computers for keeping track of accounts, money, or items that they need. You may notice business people using computers a lot, especially the laptop computers, portable computers that can be taken to your work area.
- 30. The Impact on Environment Another area computers impacted on is the entertainment area. Most of the people out there like science fiction or action movies, especially the ones with the neat looking effects. Well, those graphics were mostly made by computers. Most of the movies today use computer graphics to make things more realistic but not real. Computer graphics are mostly used on spaceships, aliens, monsters, and special effects. Movies like Jurassic Park, Wing Commander, Starship Troopers, used computers to make them look more interesting and realistic.
- 31. The Impact on Health On Health An important field computers impacted on is the medical field. The computers helped the hospitals out very much. In pharmacies, the pharmacists use computers to keep a record of what medication to give to a patient and the amount they need. Most computers in the hospital are used to keep data of patience and their status. Computers also keep track of equipment placement and status as well
