Presentation of Group 2 - Computer History

It is the computer history

1. GOOD DAY EVERYONE EYY! ARE YOU GUYS READY LETS GET STARTED!

2. This Are The Presentation of Group 2

3. The Second Generation of Computer

4. . THE SECOND GENERATION OF COMPUTERS The second generation computers were used during 1957-1963. They are also known as transistor computers. The second generation of computers consists of two types of devices, transistors, and magnetic core. The transistors helped to develop a better computer than the first generation computers consisting of vacuum tubes. Some second generation of computers are IBM 1920, IBM 7094, CDC 1604, CDC 3600, IBM 1401

5. The computers made in the second generation were completely based upon transistors, not on vacuum tubes. Until the late 1950s, the use of transistor did not see widespread in computers; however, it was invented at Bell Labs by Walter H. Brattain (1902-1987), John Bardeen (1908-1991), and William B. Shockley (1910-1989) in 1947. It was evident to many by 1948, the vacuum tube would probably replace by a transistor in the devices such as television sets, computers and radios. The below image represents that how looks the transistors

6. As compared to IBM's vacuum-tube predecessor, the IBM 709, the IBM 7090 has six times faster computing speed as it fully transistorized system. Although the IBM 7090 was specially designed for the design of jet engines, missiles, supersonic aircraft and nuclear reactors, as it was a general-purpose data processing system. In the IBM 7090, an advanced, extremely fast magnetic core storage and over 50,000 transistors were included. When eight data channels are in use, the new system has the ability to read and write 3,000,000 bits per second in one go. In the magnetic core storage, it has the ability to find and make ready for using any of 32,768 data or instruction numbers in 2.18 millionths of a second. Additionally, the following operations can be performed by the IBM 7090 in one second: 229,000 additions or subtractions as well as 39,500 multiplications, or 32,700 divisions.

7. The second-generation computers had several features, which are as follows: As the computers made in the second generation used transistors that made them more reliable, smaller in size, faster in speed, more energy-efficient, and cheaper compared to the first generation of computers. They contain magnetic storage disks and magnetic core memory. They used high-level languages such as Fortran and Cobol and allowed communication with the help of a telephone line.

8. The speed and reliability were improved in the second-generation computers as compared to the computers made in the first generation; the data processing time reduced from milliseconds to microseconds.

9. And That Was The Second Generation of computer

10. And that’s all Thankyouu!
