  COMPUTER AND ITS COMPONENTS 

 Computer itself a combination of different types of separate electronic device. computer only will be computer if it has  INPUT DEVICE, PROCESS UNIT, and OUTPUT DEVICE.
  • CENTRAL PROCESSING UNIT (CPU): It is heart and mind of computer without this unit computer unable to process.
  • KEYBOARD: This is an input device which is used to input the data into the computer.
  • MOUSE: This is also an input device which is used to input the data into computer.
  • MONITOR: This is an output device which used to show the result of the instructions.

There are variety of monitor available in the market such as, CRT Monitor , LCD Monitor , Touch screen monitor, TFT monitor etc.
  • SWITCHED MODE POWER SUPPLY (SMPS): This is an electronic device which is used to manage the power supply of computer.
  • HARD DISK(HDD): This is used to store the data in massive amount .There are so many types of HDD available in the market i.e. SATA, PATA, External HDD, and internal HDD. 
  • PRINTER: This is an output device which is used to show the result on the paper. there is plenty of printer available in the market like laser printer, inkjet, dot matrix printer etc.
  • UNIVERSAL SERIAL BUS(USB): This is used to connect the external device to the computer.
  • ETHERNET CABLE: This is used to connect with other computer.
  • CD/DVD/ROM: This is used to store the data.
  • SPEAKER: This is an output device which is used to listen voice, songs, etc.

  • RANDOM ACCESS MEMORY (RAM): This is called primary memory. this is also called main memory of the computer. whatever data is written in memory is lost after switching off the system.
  • READ ONLY MEMORY(ROM): This is called primary memory. data is written in this memory by the vendor of the computer permanently.
  • PEN DRIVE: This is very popular device now a days for carrying data on move.
  • BLUE RAY DISK: This is same as CD/DVD but only different is it can store multi time of data form CD/DVD and faster

  • MACHINE LEVEL LANGUAGE: This is low programming language. computer or any electronic device only understand this language i.e. binary number 0 and 1.
  • ASSEMBLY LEVEL LANGUAGE: This is a low level programming language which is converted into executable machine code by a utility programming reffered to as an assembler.
  • HIGH LEVEL LANGUAGE: High level language is a programming language which is easily understanding/readable by human.,
  • INTERPRETED: This is a convertor which converts high level language programme to low level language programer line by line.
  • COMPILER:This is also a converter which convert whole high level language programme to low level language programme at a time.

NUMBER SYSTEM 

  • BINARY NUMBER SYSTEM : It has only base 2 i.e. 0 and 1.
  • OCTAL NUMBER SYSTEM  : Base of octal is  8 I.E. 0,1,2,3,4,5,6,7
  • DECIMAL NUMBER SYSTEM : Base of decimal is 10 i.e 0123456789
  • HEXADECIMAL NUMBER SYSTEM : Base of this number system is 0123456789ABCDEF


OPERATING SYSTEM 

  • WINDOWS: This is a proprietary operating system and vendor is microsoft i.e. windows 2007, window vista, window 2008, window 10 etc.
