- 9. Analytical Engine • Was the first general purpose computer of the world • It was designed as mechanical computer that could perform any kind of calculation. The abacus, also called a counting frame, is a calculating tool which has been used since ancient times. Abacus
- 11. 1940 – 1956: First Generation – Vacuum Tubes A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry.
- 12. 1956 – 1963: Second Generation – Transistors A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes
- 13. 1964 – 1971: Third Generation – Integrated Circuits An integrated circuit (IC), sometimes called a chip, microchip or microelectronic circuit, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, diodes and transistors are fabricated.
- 14. 1972 – 2010: Fourth Generation – Microprocessors • A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit.
- 15. 2010- : Fifth Generation – Artificial Intelligence
- 16. Capabilities and Limitations of Computer Systems
- 17. Speed Speed means the duration computer system requires in fulfilling a task or completing an activity. It is well-known that computers need very little time than humans in completing a task. Generally, humans take into account a second or minute as a unit of time. Capabilities of a Computer System
- 18. Accuracy Accuracy means the level of precision with which calculations are made and tasks are performed. One may invest years of his life in detecting errors in computer calculations or updating a wrong record Reliability Reliability is the quality due to which the user can stay dependable on the computer. Computers systems are well-adjusted to do repetitive tasks. They never get tired, bored or fatigued. Hence, they are a lot reliable than humans.
- 19. Adaptability Adaptability of computer system means the quality of it to complete a different type of tasks: simple as well as complex. Computers are normally versatile unless designed for a specific operation. Overall, a daily purpose computer is used in any area of application: business, industry, scientific, statistical, technological and so on Storage Storage is the ability of the computer to store data in itself for accessing it again in future. Nowadays, apart from having instantaneous access to data, computers have a huge ability to store data in a little physical space.
- 20. LIMITATIONS OF COMPUTER SYSTEM Limitations are the drawbacks of the computer system in which humans outperform them.
- 21. Lack of common-sense This is one of the major limitations of computer systems. No matter how efficient, fast and reliable computer systems might be but yet do not have any common sense because no full-proof algorithm has been designed to programme logic into them. As computers function based on the stored programme(s), they simply lack common sense.
- 22. Zero IQ Another of the limitations of computer systems is that they have zero Intelligence Quotient (IQ). They are unable to see and think the actions to perform in a particular situation unless that situation is already programmed into them. Computers are programmable to complete each and every task, however small it may be.
- 23. Lack of Decision-making Decision-making is a complicated process involving information, knowledge, intelligence, wisdom, and ability to judge. The computer system does not have the ability to make decisions on their own because they do not possess all the essentials of decision-making.
- 24. Graphic Tools and Desktop Publisher
- 25. Graphic Tools a graphic tool is a software application or platform that makes use of visual effects to improve any content.
- 27. Desktop Publisher Desktop publishing is the use of a computer to produce high-quality documents containing text and graphics formatted for a single-page publication. For example, desktop publishing is utilized to create printed material, such as book covers, brochures, catalogs, flyers, magazines, and posters
- 28. Database • The function of a database is to collect and organize input data. • A database is managed by a database management system (DBMS), systems software that provides assistance in managing databases shared by many users.
- 29. Database Management System (DBMS) A database management system (DBMS) is a software package designed to, manipulate, retrieve and manage data in a database. A DBMS generally manipulates the data itself, the data format, field names, record structure, and file structure. It provides users and programmers with a systematic way to create, retrieve, update and manage data.
- 30. The Database Management System performs the following functions: Data Dictionary Management, Data Storage Management, Data Transformation and Presentation, Security Management, Multi-User Access Control, Backup and Recovery Management, Data Integrity Management, Database Access Languages and Application Interface, Database Communication Interface.
- 31. Similarities between Hardware and Software Development They have behavior: Users interact with the products in various ways, products interact with other products, and products produce outputs given inputs They have functional (user-facing) and non-functional (non-user- facing) requirements They are complex: Any representation of product specifications invariably leads to a tree structure, as major features are decomposed into finer-grained features
- 34. Purpose of Computers in Education • Computers are one of the most valuable resources in a classroom because they serve so many useful functions. With computers and the internet, students today have a wealth of information at their fingertips that can help them develop their research and communication skills while preparing them for a future career in a workforce that is increasingly reliant on computer technology.
- 35. Roles of Computer in Education 1.Computers are a brilliant aid in teaching. Online education has revolutionized the education industry. Computer technology has made the dream of distance learning, a reality. Education is no longer limited to classrooms. 2.Computers have given impetus to distance education. Computers facilitate effective presentation of information. Presentation software like PowerPoint and animation software like Flash among others can be of great help to teachers while delivering lectures.
- 36. 3.Computer software help better presentation of information. Teachers can refer to it for additional information and references on the topics to be taught. Students can refer to web sources for additional information on subjects of their interest 4.Computers enable access to the Internet which has information on literally everything. Computers enable storage of data in the electronic format, thereby saving paper. Memory capacities of computer storage devices are in gigabytes.
- 37. 5.Computer, hard drives and storage devices are an excellent way to store data. This was about the role of computers in education. But we know, it's not just the education sector which computers have impacted. They are of great use in every field. Today, a life without computers is unimaginable. This underlines the importance of computer education.
- 38. The advantages of computers in education primarily include: Storage of information Quick data processing Audio-visual aids in teaching Better presentation of information Access to the Internet Quick communication between students, and parents
- 39. DISAVANTAGES OF COMPUTER IN EDUCATION
- 40. Technical Problems For online learning courses or classes requiring network access, technical issues can cause major problems. A lost or stolen computer might prohibit a student from logging onto a discussion forum.
- 41. Spelling and Handwriting Skills When students replace paper and pen with a computer for education, handwriting skills may suffer. Adult learners benefit from increased brain activity when writing new information by hand, particularly in subjects such as math and chemistry. Most computer word processing programs include a spelling and grammar check, and students might rely too heavily on the computer to correct spelling and grammatical errors.
- 42. Cheating Using computers to cheat is a widespread problem in universities and colleges. Students might search online for answers to test questions or have answers sent to their computers by other students. Students are able to access huge amounts of information via computers and may present that information as their own. Plagiarizing may be difficult for universities to prove or identify because of the broad scope of the Internet and difficulty of finding all possible sources of information.
- 43. Financial Problems Financial problems may prohibit some students from owning a computer, placing them at a disadvantage. Low-income college students are less likely to have easy access to a computer and may not have learned basic computer skills that other students learned at a young age.
- 44. Computer Tools Traditional Tools Helps teacher plan, implement and evaluate instruction Teachers planned and implemented instruction using typewriters, pencil, and paper. To record grades, calculate averages, manage attendance and access data on student performance in online programs and assessments. Computers have also made it easier for teachers to vary their instructional delivery Traditional instructional materials are the materials traditionally used by the teachers to their students in teaching their lessons. It includes the use of textbook, chalk, board, marker, charts and flash cards. These are the common materials that help the teachers to the lesson clearly.
