Commonly consisting of digital circuitry, that accepts (inputs), stores, and generates (outputs) data as numbers, text, graphics, voice, video files, or electrical signals. Father of the computer - Charles Babbage Father of the modern computer - Alan Turing Basic Architecture of Computer: John Von Neumann (1947-49) First Programmer: Lady Ada Lovelace (1880) First Electronic Computer: ENIAC (1946) - J.P. Eckert & J.W. Mauchly A first computer for the home user introduced - IBM in 1981 Generation of Computer There are five generations of computers. FIRST GENERATION 1946-1959 is the period of the first-generation computer. J.P. Eckert and J.W. Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numerical Integrator And Computer”. Advantages: i)It made use of vacuum tubes which are the only electronic component available during those days. ii) These computers could calculate in milliseconds. Disadvantages: i)These were very big in size, weight was about 30 tones. ii) These computers were based on vacuum tubes. iii) These computers were very costly. iv) It could store only a small amount of information due to the presence of magnetic drums. IBPS | SBI | RBI | SEBI | SIDBI | NABARD | SSC CGL | SSC CHSL | AND OTHER GOVERNMENT EXAMS 3 ambitiousbaba.com Online Test Series v) A large amount of energy consumption. SECOND GENERATION 1959-1965 is the period of a second-generation computer. Second-generation computers were based on Transistors instead of vacuum tubes. Example : Honeywell 400, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108 Advantages: i)Due to the presence of transistors instead of vacuum tubes, the size of the electron component decreased. This resulted in reducing the size of a computer as compared to first-generation computers. ii) Less energy and not produce as much heat as the first generation. iii) Assembly language and punch cards were used for input. iv) Low cost than first-generation computers. v) Better speed, calculate data in microseconds. Disadvantages: i)A cooling system was required. ii) Constant maintenance was required. iii) Only used for specific purposes. THIRD GENERATION 1965-1971 is the period of the third-generation computer. These computers were based on Integrated circuits. IC was invented by Robert Noyce and Jack Kilby In 1958-1959. IC was a single component containing a number of transistors. Examples: PDP-8 ,PDP-11, ICL 2900, IBM 360 Advantages: i)These computers were cheaper as compared to second-generation computers. ii) They were fast and reliable. iii) The use of IC in the computer provides the small size of the computer. IBPS | SBI | RBI | SEBI | SIDBI | NABARD | SSC CGL | SSC CHSL | AND OTHER GOVERNMENT EXAMS 4 ambitiousbaba.com Online Test Series iv) IC not only reduces the size of the computer but it also improves the performance of the computer as compared to previous computers. v) This generation of computers has a big storage capacity. Disadvantages: i)IC chips are difficult to maintain. ii) The highly sophisticated technology required for the manufacturing of IC chips. FOURTH GENERATION 1971-1980 is the period of the fourth-generation computer. This technology is based on Microprocessor. A microprocessor is used in a computer for any logical and arithmetic function to be performed in any program. Graphics User Interface (GUI) technology was exploited to offer more comfort to users. Examples: IBM 4341 Advantages: i)Fastest in computation and size get reduced as compared to the previous generation of computers. ii) The heat generated is negligible. iii) Small in size as compared to previous generation computers. Disadvantages: i) Microprocessor design and fabrication are very complex. ii) Air conditioning is required in many cases due to the presence of ICs. FIFTH GENERATION The period of the fifth generation in 1980-onwards. This generation is based on artificial intelligence. The aim of the fifth generation is to make a device that could respond to natural language input and are capable of learning and self-organization. This generation is based on ULSI (Ultra Large Scale Integration) technology resulting in the production of microprocessor chips having ten million electronic components. Examples: Desktop, Laptop, Note-Book IBPS | SBI | RBI | SEBI | SIDBI | NABARD | SSC CGL | SSC CHSL | AND OTHER GOVERNMENT EXAMS 5 ambitiousbaba.com Online Test Series Chapte 2: Classification of Computers 1. Digital computer -Digital computer is the most commonly used type of computer and is used to process information with quantities using digits, usually using the binary number system. Ex - MacBook. 2. Analog Computer - A computer that operates with numbers represented by directly measurable quantities (as voltages or rotations) — compare digital computers, hybrid computers. 3. Hybrid Computer - A computer that combines the characteristics of a digital computer and an analog computer by its capacity to accept input and provide output in either digital or analog form and to process information digitally. Classification on size 1. Mainframe computer - A mainframe computer is a very large computer capable of handling and processing very large amounts of data quickly. They are used by large institutions, such as government agencies and large corporations. 2. Mini Computer - a computer with processing and storage capabilities smaller than those of a mainframe but larger than those of a microcomputer. 3. Micro computer - A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC , a computer designed for an individual. 4. Personal computer - A personal computer (PC) is a small, relatively inexpensive computer designed for an individual user. In price, All are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. 5. Supercomputer - The fastest type of computer.

It helps to enter data on the computer. Mouse - A mouse is used to input data by sending a signal to the computer, based on hovering the cursor and selecting with the left mouse button. The left mouse acts as an 'enter' button. The right mouse button can be selected and will often pop up a window of choices. The scrolling wheel is used to move the view of the screen up or down. By moving your mouse to a location in a document, on a digital photo or over a choice of music, you can click the left mouse button to place the cursor. Trackball - A trackball is an input device used to enter motion data into computers or other electronic devices. It serves the same purpose as a mouse but is designed with a moveable ball on the top, which can be rolled in any direction. Instead of moving the whole device, you simply roll the moveable ball on top of the trackball unit with your hand to generate motion input. Barcode reader - A barcode reader (or barcode scanner) is an electronic device that can read and output printed barcodes to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Digital camera - A camera is a device which produces digital images that can be stored in a computer and displayed on the screen. Gamepad - A handheld controller for video games. Joystick – A lever that can be moved in several directions to control the movement of an image on a computer or similar display screen. It mainly used in playing games. Microphone - An instrument for converting sound waves into electrical energy variations which may then be amplified, transmitted, or recorded. Scanner - A device that scans documents and converts them into digital data. Webcam - A video camera connected to a computer, allowing its images to be seen by Internet users. Optical character recognition (OCR) - It is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text. Digitizer - It converts analog information into digital form. Optical Mark Reader (OMR) - Optical Mark Readers reads pencil or pen marks made in pre-defined positions on paper forms as responses to questions or tick list prompts. Output devices IBPS | SBI | RBI | SEBI | SIDBI | NABARD | SSC CGL | SSC CHSL | AND OTHER GOVERNMENT EXAMS 20 ambitiousbaba.com Online Test Series An output device is any device used to send data from a computer to another device or user. Most computer data output that is meant for humans is in the form of audio or video. Example: Computer monitor, Printer, PC speaker, headphone, Projector, Sound card, Video card. Monitor - A Monitor is a TV-like display attached to the computer on which the output can be displayed and viewed. It can either be a monochrome display or a colour display. Two types of monitors: 1)CRT (Cathode ray tube) - The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns, and a phosphorescent screen used to view images. 2) Thin-Film-Transistor Liquid-Crystal Display (TFT LCD) - A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display (LCD) that uses thin- film transistor technology to improve image qualities such as addressability and contrast. Printer - Printer is an output device for printing text or pictures. Two types of Printer: 1) Impact printer - An impact printer is a printer that strikes a print head against an ink ribbon to mark the paper. Common examples include Dot-matrix and daisy-wheel printers. 2) Non-Impact printer - Non-impact printers print the characters without using ribbon. Two common types of non-impact printers include inkjet printers, which spray small drops of ink onto each page, and laser printers, which roll ink onto the paper using a cylindrical. CPU (Central Processing Unit) A Central Processing Unit (CPU), also called a central processor or main processor, is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions. The computer industry has used the term "central processing unit" at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
