These computer were large in size & their programming was difficult task. The key to the success was in the stored instructions which it depended upon solely for its operation. + qs; Computers can be generally classified by size and power as follows, though there is Considerable overlap: • Personal computer: A small, single-user computer based on a microprocessor. The beginning of commercial computer age is from UNIVAC (Universal Automatic Computer). 5. Recent Computer Notes in Hindi. { The computers of electronic age are further divided into 5 generation on the basis of technology used by the computer. Being extremely motivated to meliorate computer products, engineers marked later the third generation with more sophisticated computers (IBM 360). During this generation over 100 computers, programming languages were developed, computers had memory and operating systems. The Third generation computers used the integrated circuits (IC). Computers can understand spoken words & imitate human reasoning. Mark I is the first machine to successfully perform a long services of arithmetic and logical operation. Very soon ICs Were replaced by LSI (Large Scale Integration), which consisted about 100 components. This note provide us the information about generation of computer. this was really helpful. The Microprocessor contains thousands of ICs. The computers of third generation used Integrated Circuits (ICs) in place of transistors. Manufacturing cost was also very low. Semi conductor memory devices were used. 2. Input was based on punched cards and paper tape, and output was displayed on printouts. The period of third generation was from 1965-1971. The machine was 25 feet by 50 feet in length, contained 5,600 tubes, 18,000 crystal diodes, and 300 relays. 6. This website uses cookies to ensure you get the best experience on our website. Large Scale Integration (LSI) and Very Large Scale Integration (VLSI) were also developed. Today your favorite computer is many times as powerful as ENIAC, still size is very small. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). EDVAC: It stands for Electronic Discrete Variable Automatic Computer and was developed in 1950.it was to be a vast improvement upon ENIAC, it was binary rather than decimal, and was a stored program computer. Its reported processing speed was 0.525 milliseconds for arithmetic functions, 2.15 milliseconds for multiplication and 3.9 Milliseconds for division. Fifth Generation of Computer is total Artificial Intelligent Computer. Instead the Mark I was constructed out of switches, relays, rotating shafts, and clutches. Highly sophisticated technology required for the manufacturing of IC chips. The computer age was characterized by generation of computers, which signified that computer had pass through stages of evolution or development. Data flow & EPIC architecture of these processors have been developed. The development of electronic computers can be divided into five generations depending upon the technologies used. First generation (1940 - 1956) The first generation of computers used vacuum tubes as a major piece of technology. The size of the computers was decreased by replacing vacuum tubes with transistors. ENIAC contained 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints. First Generation (1940-1956) Vacuum Tubes 2. ), and magnetic core storage. A single IC has many transistors, registers and capacitors built on a single thin slice of silicon. Higher level language such as BASIC (Beginners All purpose Symbolic Instruction Code) was developed during this period. Starting from 1940s, computers’ performance, measured in terms of processing speed, storage capacity, accuracy of results, multi-tasking ability and versatility has improved significantly. They stored information in the form of propagating sound waves. The examples of third generation computers are IBM 370, IBM System/360, UNIVAC 1108 and UNIVAC AC 9000 etc. These computers could calculate data in millisecond. EDSAC: It stands for Electronic Delay Storage Automatic Computer and was developed by M.V. 3. 2. Vacuum tubes were widely used in computers from 1940 through 1956.Vacuum tubes were larger components and resulted in first generation computers being quite large in size, taking up a lot of space in a room. All types of High level languages can be used in this type of computers. Generations of computers has been divided into five according to … Smaller in size as compared to the first generation computers. the first ‘computer’ to use electronic valves (ie. The different generations are: i) First Generation of computers ii) … Functionality and Advantages of Using Alphanumeric Code. A list of popular first generation computers ENIAC, UNIVAC,EDVAC, and EDSAC. Their size varies from desktop to laptop or palmtop. Fifth Generation of Computer is total Artificial Intelligent Computer. (v)    Fifth Generation (1991- continued) : 5th generation computers use ULSI (Ultra-Large Scale Integration) chips. The JOHNNIAC was named in honor of Jon Von Neumann. The Microprocessor contains thousands of ICs. 6. Every stage of technological advancement in computer development is referred to as a ‘Generation of Computer’. History of Computers The Second Generation • Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. o Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system. A) Computer Characteristics & … I/O processor was included to control I/O operations. Vacuum tube technology made possible to make electronic digital computers. Generation of computer notes. Fourth Generation of Computer (PC 1975 – Cu rrent) At this time of technological development, the size of computer was re - divided to what we called Personal Computers, PC. The examples of second generation computers are IBM 7094 series, IBM 1400 series and CDC 164 etc. Grid Computing: What Is It And What Are Its Benefits? Initially, the generation term was used to distinguish between varying hardware technologies. It was an important invention in the computer field. Computer Notes for banking on generations of computers. Third-generation of computers(1964-1971) IC (integrated circuit) was the hallmark of the third generation computers. Used fan for heat discharge to prevent damage. Evolution of Computer Generations. UNIVAC-1: Ecker and Mauchly produced it in 1951 by Universal Accounting Computer setup. Transistors were used instead of Vacuum Tube. Illustration of the third generation computers was system 360 mainframe from IBM, PDP-8, Mini computers from digital equipment corporation, NCR 395 and B6500. It utilized serial circuitry, 2.25 MHz bit rate, and had an internal storage capacity 1,000 words or 12,000 characters. The history of the computer goes back several decades however and there are five definable generations of computers. 4. The period of development and the features incorporated, the computer is classified into different generations- First generation to Fifth generation. Hard disks were used as secondary memory. wid: "476964", Similar Topics: Types of Computers by Purpose  | Types of Printers. The first electronic computer was designed and built at the University of Pennsylvania based on vacuum tube technology. Multiprogramming facility was developed.Size, cost, power requirement and heat generation decreased. It is in the second generation that the concept of Central Processing Unit (CPU), memory, programming language and input and output units were developed. Their computing capabilities were limited. 3. Fast processing power with less power consumption. » The second generations computers were more reliable. Computers of this generation were small in size, low cost, large memory and processing speed is very high. (ii)  Second Generation (1955-1964) : The second-generation computer used transistors for CPU components & ferrite cores for main memory & magnetic disks for secondary memory. In this stage Parallel Processor and ULSI (Ultra Large Scale Integration) is introduced. The period of first generation was from 1946-1959. Thus the computer which was occupying a very large room in earlier days can now be placed on a table. IBM 1620: Its size was smaller as compared to First Generation computers and mostly used for scientific purpose. An IC containing about 100 components is called LSI. Mark I is the First Generation Computer. This is called the computer generation. Magnetic drums are also used for storage .At that time memory was very expensive. They were large in size, slow in processing and had less storage capacity. Third generation was SSI (small-scale integration), starting with the IBM System/360 in 1963 and going until about 1980. More powerful and reliable than previous generations. Computers at this time were usually kept in special locations like government and university research labs or military compounds. They used machine level language for programming. Vacuum tubes were used to perform logic operations and to store data. The machine weighed 5 tons, incorporated 500 miles of wire, was 8 feet tall and 51 feet long, and had a 50 ft rotating shaft running its length, turned by a 5 horsepower electric motor. 5.
