Ch 1 introduction and 2 computer software 1
Ch 1 introduction and 2 computer software 1rjsuthar56 The document summarizes the evolution of computers over five generations from the 1950s to present:
- The first generation used punched cards for input and vacuum tubes for memory and storage. High-level programming languages were developed.
- The second generation replaced vacuum tubes with transistors, enabling faster and more reliable computers. Timesharing allowed multiple users to access mainframe computers remotely via terminals.
- The third generation saw the development of integrated circuits and microprocessors, allowing for smaller computers. Networks like ARPANET, the precursor to the Internet, were established.
- The fourth generation featured microcomputers powered by microprocessors like the Intel 8080. The IBM PC launched in 1981, popularizing the use of microcomputers
Classification of Computers
Classification of ComputersHina Anjum There are three main types of computers based on their principles of operation: analog computers, digital computers, and hybrid computers. Digital computers are the most common today and operate using binary numbers. Computers can also be classified based on their size, memory capacity, and processing speed into supercomputers, mainframe computers, mini computers, and microcomputers (personal computers). Microcomputers are the most ubiquitous. Computers also have different functions and configurations including servers, workstations, information appliances, and embedded systems. Buses and ports allow for communication between different computer components. A modem facilitates data transmission over telephone or cable lines by converting between digital and analog formats.

- 2. Types of computer Type of computer Digital computer Analog computer Hybrid Computer Main frame Micro Computer Super Computer Mini Computer Computer Home PC
- 3. Analog computer Analog computer measures and answer the questions by the method of “HOW MUCH”. The input data is not a number infect a physical quantity like tem, pressure, speed, velocity. Signals are continuous of (0 to 10 V) Accuracy 1% Approximately High speed Output is continuous Time is wasted in transmission time
- 5. Digital Computers Digital computer counts and answer the questions by the method of “HOW Many”. The input data is represented by a number. These are used for the logical and arithmetic operations. Signals are two level of (0 V or 5 V) Accuracy unlimited low speed sequential as well as parallel processing Output is continuous but obtain when computation is completed.
- 6. Micro Computer Micro computer are the smallest computer system. There size range from calculator to desktop size. Its CPU is microprocessor. It also known as Grand child Computer. Application : - personal computer, Multi user system, offices.
- 7. Mini Computer These are also small general purpose system. They are generally more powerful and most useful as compared to micro computer. Mini computer are also known as mid range computer or Child computer. Application :- Departmental systems, Network Servers, work group system.
- 9. Main Frame Computer Mainframe computers are those computers that offer faster processing and grater storage area. The word “main frame” comes from the metal frames. It is also known as Father computer. Application – Host computer, Central data base server.
- 10. Super Computer Super computer are those computer which are designed for scientific job like whether forecasting and artificial intelligence etc. They are fastest and expensive. A super computer contains a number of CPU which operate in parallel to make it faster. It also known as grand father computer. Application – whether forecasting, weapons research and development.
