Explanation

The brain of the computer is the CPU

CPU stands for the central processing unit

The first commercial CPU was invented by Italian Physicist Federico Faggin

The first CPU was the Intel 404 released by Intel in 1971.

**

The five basic parts of a computer are:

1. the motherboard
2. central processing unit (CPU)
3. input-output units
4. memory (RAM and ROM)
5.  storage (SSD or HDD)

AGM 07.5.23

Explanation

Karachi is called the "Gateway of Pakistan"

It has an ideal location and well-developed connections to form gateways region with:

• Afghanistan,
• Central Asia,
• and Western China

Additional information:

It was the first capital of Pakistan.

It is the biggest city in Pakistan.

The capital of Karachi is Sindh.

Explanation

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves.

Leo is called the first-generation computer.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation

An integrated circuit is a set of electronic circuits on one small flat piece  of semiconductor material, usually silicon.

Large numbers of tiny MOSFETs  integrate into a small chip. 

First generation (1940 - 1956)  vacuum tubes as a major piece of technology.

 The ENIAC is  example of 1st generation computer.

Second generation (1956 - 1963) use of transistors.

Third generation (1964 - 1971)  use of Integrated circuits.

Fourth generation (1972 - 2010) use of the microprocessor

Fifth generation (2010 to present) use Artificial intelligence

Explanation

The CP of the gun = Rs. 2500

The SP of the gun = Rs. 900

The loss is = CP - SP = Rs. ( 2500 - 900 )

= Rs. 1600

Hence, the loss incurred by Akbar is 64%.

Explanation

Hybrid computers can perform the tasks of  digital and analogue computer

These computers are used in aircraft, hospitals where measuring physical quantities and converting them into digital data to analysis is required.

AGM 07.5.23

Explanation

2 ×  2 = 4

4 ×  2 = 8

8 ×  2 = 16

16 ×  2 = 32

Explanation

120 men can do work = 30 days

1 man can do this work = 120 x 30 = 3600 days

80 men can do this work = 3600/80 = 45 days

Explanation

Month of Sundays means a very long time ago.

Month of Sundays بہت عرصہ پہلے
