  • An assembly language is a low-level programming language for computers, microprocessors, micro controllers, and other programmable devices.
  • A program written in assembly language consists of a series of (mnemonic) processor instructions and meta-statements (known variously as directives, pseudo-instructions and pseudo-ops), comments and data.
  • Machine language is a collection of binary digits or bits that the computer reads and interprets.
  • FORTRAN, BASIC, COBOL, C/C++, Pascal are some examples for High-Level Programming Languages.
  • The ability to recover and read deleted or damaged files from a criminal’s computer is an example of a law enforcement specialty called computer forensics.
  • Firefox (Mozilla), Internet Explorer (Microsoft) and Chrome (Google) are the most popular browsers today.
  • Surgeons can perform delicate operations by manipulating devices through computers instead of manually. This technology is known as robotics.
  • Artificial intelligence (AI) is the science that attempts to produce machines that display the same type of intelligence that humans do.
  • The term bit is short for binary digit.
  • Linux, UNIX, Microsoft’s Windows, DOS, Vista, Windows 7 and Apple’s MacOS are some examples of computer operating systems.
  • Hardware is any part of the computer that you can physically touch.
  • Software is a set of computer programs used on a computer to help perform tasks.
  • Supercomputers are specially designed computers that perform complex calculations extremely rapidly.
  • The operating system controls the way in which the computer system functions and provides a means by which users can interact with the computer.
  • HTTP stands for Hypertext Transfer Protocol
  • WWW (W3) – World Wide Web
  • FORTRAN – Formula Translation / Translator
  • BASIC – Beginners All-purpose Symbolic Instruction Code
  • COBOL – Common Business Oriented Language
  • FTP – Transfer Protocol
  • TCP/IP – Transmission Control Protocol / Internet Protocol
  • SMTP – Simple Mail Transfer Protocol
  • POP – Post Office Protocol
  • ENIAC – Electronic Numerical Integrator and Calculator
  • DLL – Dynamic Link Library
  • Facebook, Twitter, Orkut are some examples for social networking websites.
  • PARAM is a series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India. PARAM 8000, PARAM 8600, PARAM 9900, PARAM 10000, PARAM Padma, PARAM Yuva are the PARAM series supercomputers.

  • Examples of input devices include the keyboard, mouse, modem, joystick, digitizing pen and tablet, microphone, touch screens, scanner, camera etc.
  • Examples of output devices include speakers, monitor, printers etc.

  • Examples of storage devices include the hard drives, floppy drives, tape drives, CD-ROM drives etc.

  • The earliest known device to record computations was the abacus. It dates back to ancient times and was invented by the Chinese.

  • John Napier discovered logarithms.

  • Charles Babbage, a British Mathematics professor, is regarded as the Father of Computers.

  • Charles Babbage designed and built a model of what was called the difference engine. Babbage then designed the analytic engine

  • In First Generation Computers (1951-1958) vacuum tubes are used in electronic circuits.

  • In Second Generation Computers (1959-1964) transistors are used for internal operations.

  • In Third Generation Computers (1965-1970) integrated circuits (Ics) replaced the transistors of the second generation machines.

  • Fourth Generation computers are the modern day computers. Introduction of microprocessors and microcomputers, Use of large scale integrated circuits.

  • Fifth generation computing devices, based on artificial intelligence, are still in development.

  • Advanced Research Projects Agency Network (ARPANET) was the first Internet.
  • Vinton Cerf is known as the father of the internet.
  • Tim BernersLee – Inventor of the World Wide Web (WWW) in 1991.
  • Google began in January 1996 as a research project by Larry Page and Sergey Brin.
  • The smallest amount of transfer is one bit. It holds the value of a 1, or a 0 (Binary Coding). Eight of these 1’s and zeros are called a byte.
  • Commonly used memory terms:

          1 bit = 1 or 0
          4 bits = 1 nibble (often nybble or even nyble)
          8 bits = 1 byte (B)
          1024 bytes = 1 Kilobyte (KB)
          1024 Kilobytes = 1 Megabyte (MB)
          1024 Megabytes = 1 Gigabyte (GB)
          1024 Gigabytes = 1 Terabyte (TB)

  • IBM introduced its first personal computer called the IBM PC in 1981.
  • Facebook is a social networking service and Web site launched in February 2004.
