computer fundamentals notes in hindi pdf

Vi) These computer systems use RAM for temporary data storage V) A greater versatility of Input/Output devices is introduced Iv) Storage capacity and speed of the systems are increased. Iii) In this generation use of microcomputers is increased Ii) Modular designs are available for the users. I) These computer systems use Large Scale IC Chips Vii) Size of the systems was reduced and perform better performance or these systems are reliable for the usesĮxample: IBM System/360, NCR 395, Burroughs B6500, etc. Vi) And Operating Systems are available for Input/Output in these computer systems V) High-Level Programming Languages are used in these systems. Iv) Working speed of these systems is also increased. Iii) Input and Output are more flexible in these systems. Ii) And Magnetic Core also uses for primary storage. I) These systems replace transistors with IC (Integrated Circuit) Chips. Vii) High-Level Programming Languages are used in these systems (COBOL and FORTRAN).Įxample: IBM-1401, Honewell 200, CDC 1607, etc. Vi) Reduces the size of the entire computer system and these systems generate less heat. V) Input/Output speed was fast as compared to the first-generation computer system. Iv) And Punched Card or Magnetic Tapes are used in these computer systems.

Iii) In this generation main storage capacity and speed are increased. Ii) And use Magnetic core as Primary Internal Storage. I) Transistors are used at the place of vacuum tubes. Vii) Constant maintenance is required for these systems. And very expensive to operate and I/O ( input/ output) is very slow. Vi) These systems consume a large amount of energy. V) Takes entire room space for a single system. Iv) These systems can calculate in milliseconds. Iii) Vacuum tubes are used to store instructions. I) Computer Systems are Entirely electronic. The development of computer systems is normally discussed as the development over different generations. The Output Units translate the computer's data into human-readable form. It creates the link between user and computer. Output Units are used to get information from a computer system. It controls the operations of all parts of the computer but does not carry out any actual data processing. Mainly memory unit is known as Internal, Main & Primary memory, or RAM (Random Access Memory). It sends the information to other units when required. Memory is used to store instructions, data & intermediate results. * Components of CPUĪ) Arithmetic Section- It performs all the arithmetic operations like addition, subtraction, multiplication, and division.ī) Logic Section - It performs logical operations such as comparing, matching, selecting & merging data. Mainly CPU controls the operations of the computer's parts. It stores intermediate results, programs & data. CPU performs all types of data processing operations. The Input Units translate the information into computer-readable form.ĬPU is known as the Brain of the Computer. Input units are used to enter the data into a computer system.

V) Control the Workflow - directs the manner and sequence in which all of the above operations are performed. Iv) Output Information - the process of producing useful information for the users. Iii) Processing Data - performing arithmetic, and logical operations on data to convert into useful information Ii) Storing Data - save data and instruction for the future when required. I) Take Input - the process of entering data & instructions.
