Hartron Important Questions Part 5

Q:(F) What is Cell Spacing and Cell Padding?

Ans:-

Cellpadding is the amount of space between the outer edges of the table cell and the content of the cell.  Cellspacing is the amount of space in between the individual table cells.

Q:(G) What is computer? Explain the generation of computer.

Ans:-

 ( Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.)(Hartron Important Questions)

Generation of computer:-

(1.) FIRST GENERATION

* Introduction:-

(1.) 1946-1959 is the period of first generation computer.
(2.) J.P.Eckert and J.W.Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated And Calculator”.

(2). SECOND GENERATION

* Introduction:-

(1.) 1959-1965 is the period of second-generation computer.
(2.) 3.Second generation computers were based on Transistor instead of vacuum tubes.

(3.) THIRD GENERATION

* Introduction:-

(1.) 1965-1971 is the period of third generation computer.(2.) These computers were based on Integrated circuits.(3.) IC was invented by Robert Noyce and Jack Kilby In 1958-1959.(4.) IC was a single component containing number of transistors.

(4.)- FOURTH GENERATION

* Introduction:-

(1.) 1971-1980 is the period of fourth generation computer.
(2.) This technology is based on Microprocessor.
(3.) A microprocessor is used in a computer for any logical and arithmetic function to be performed in any program.
(4.) Graphics User Interface (GUI) technology was exploited to offer more comfort to users.

(5.) FIFTH GENERATION

* Introduction:-

(1.) The period of the fifth generation in 1980-onwards.
(2.) This generation is based on artificial intelligence.
(3.) The aim of the fifth generation is to make a device which could respond to natural language input and are capable of learning and self-organization.
(4.) This generation is based on ULSI(Ultra Large Scale Integration) technology resulting in the production of microprocessor chips having ten million electronic component.
