Advantages of Using Artificial Intelligence (General Topic for Classes : 8, 9, 10)

1. Increased Accuracy: AI systems are able to process and analyze large amounts of data with much higher accuracy and speed than humans, thereby reducing errors in decision making.

2. Automation: Automation of business processes leads to more efficiency, leading to more productivity and lower costs.

3. Improved Customer Service: AI chatbots can help provide customer service 24/7 without the need for manual assistance from humans.

4. Enhanced Security: AI enabled systems are able to detect and respond to security threats faster and more accurately than humans, drastically reducing the chances of a security breach.

5. Predictive Analysis: AI systems can examine large amounts of data and identify patterns, and then use that knowledge to predict outcomes and behaviors.

History of Computer (for class 6)

 History of Computer

1. The history of computers starts out about 2000 years ago in Babylonia (Mesopotamia), at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them.

2. Blaise Pascal has credited the first digital computer in 1642. The basic principle of his calculator is still used today in water meters and modern-day odometers.

3. Punched cards, which were first successfully used with computers in 1890 by Herman Hollerith and James Powers. They developed devices that could read the information that had been punched into the cards automatically, without human help.

4. Punch-card using computers created by International Business Machines (IBM), Remington, Burroughs. These computers used electromechanical devices in which electrical power provided mechanical motion -- like turning the wheels of an adding machine. Such systems included features to:

         feed in a specified number of cards automatically

         add, multiply, and sort

5. In 1942, John P. Eckert, John W. Mauchly, and their associates at the Moore school of Electrical Engineering of University of Pennsylvania decided to build a high - speed electronic computer to do the job. This machine became known as ENIAC (Electrical Numerical Integrator And Calculator) and it occupied the entire thirty by fifty feet room.

6. ENIAC was therefore about 1,000 times faster than the previous generation of relay computers. ENIAC used 18,000 vacuum tubes about 1,800 square feet of floor space, and consumed about 180,000 watts of electrical power.

7. In 1950 magnetic core memory and the Transistor - Circuit Element of digital computers. RAM capacities increased from 8,000 to 64,000 words in commercially available machines by the 1960s, with access times of 2 to 3 MS (Milliseconds).

8. In the 1980's manufacturing of semiconductor chips was done, The Intel and Motorola Corporations were very competitive into the 1980s, although Japanese firms were making strong economic advances, especially in the area of memory chips. By the late 1980s, some personal computers were run by microprocessors that, handling 32 bits of data at a time.

Define : Computer

Computer: A computer is an electronic device that can store, retrieve and process data and be programmed with instructions to carry out specific operations.

 A computer consists of Hardware and Software.

 Hardware components describe the physical parts of the

computer.

Example: Mouse, Keyboard, Speaker, etc.

 Software controls hardware and runs the operating system,

different programs & applications.

Example: Microsoft Word, Microsoft Excel, etc.
