journey of computer started in 1940 and went through a series of changes which
led the growth of different generations of computer. Give a brief description
on generations of computer.
(Listing the
various generations- 2 marks, explanations- 5 marks, Examples for each- 3 marks
)10 marks
Answer : Various
generations of computer:
The history of
computer development is often referred to in reference to the different
generations of computing devices. Each of the five generations of computers is
characterized by a major technological development that fundamentally changed
the way computers operate.
- First Generation (1940-1956) Vacuum Tubes
- Second Generation (1956-1963)
Q2. a.
Determine the decimal equivalent of the given number (34.51)8
(Decimal to
octal conversion- formula- 2 marks, Calculation- 3 marks)
Answer :
Decimal to octal conversion formula :
To convert
integer decimals to octal, divide the original number by the largest possible
power of 8 and successively divide the remainders by successively smaller
powers of 8 until the power is 1. The octal representation is formed by the
quotients, written in the order generated by the algorithm. It is one of the
most commonly explained problems in computer basics.
b. determine
the decimal equivalent of the given number (155)16
(Decimal to
hexadecimal conversion- formula- 2 marks, Calculation- 3 marks) 5+5 marks
Answer : Decimal
to hexadecimal conversion- formula:
Hexadecimal is
base 16.
Base 16 is where
the 'numbers' you can use are zero through to the letter F (0123456789ABCDEF).
i.e. the decimal value for '1' is represented in hexadecimal as '1' but the
hexadecimal value of '15' (decimal) is shown as 'F' (hexadecimal) and the value
of '17' (decimal) is '11' in Hexadecimal. Also a Hexadecimal is converted into
decimal by taking the base 16. The rest of the process is
Q3. Write
short notes on :
a. Magnetic
disc description
(explaining-3
marks figure- 2 marks)
Answer : Magnetic
disc description:
A memory device,
such as a floppy disk, a hard disk, or a removable cartridge, that is covered
with a magnetic coating on which digital information is stored in the form of
microscopically small, magnetized needles. The disk surface is divided into
concentric tracks (
b. CD ROM
description 5
(explaining-
3 marks, figure- 2 marks)
Answer : CD
ROM :
A CD-ROM is a
pre-pressed compact disc which contains data. The name is an acronym which
stands for "Compact Disc Read-only Memory". Computers can read
CD-ROMs, but cannot write on them. CD-ROMs are popularly used to distribute
computer software, including video games and multimedia applications, though
any data can be stored (up to the capacity limit of a disc).
