the first general purpose electronic digital computer designed for commercial
use, produced by Universal Accounting Company of John Mauchly and J.P.Eckert in
1951.
2. CD-ROM stands for Compact Disk
Read Only Memory, There are no objects with the name as in other options.
CD-ROM is a non-volatile optical data storage medium using the same physical
format as audio compact disk, readable by a computer with a CD-ROM drive. The
standard 12 cm diameter CD-ROM store about 660 megabytes.
3. ALU is Arithmetic Logic Unit, ALU
is a unit in Central Processing Unit in a computer system that is responsible
for arithmetic calculations and logical operations. Apart from ALU, the CPU
contains MU (Memory Unit) and CU (Control Unit).
4. VGA is Video Graphics Array, VGA is a type of Graphics Adapter. Graphic
Adapter is an electronic board that controls the display of a monitor. This
device helps the motherboard to work with the monitor and in VGA and SVGA the
last letter ‘A’ stands for ‘Array’ whereas in MDA, CGA, MCGA the last letter
‘A’ stands for ‘Adapter’.
5. IBM 1401 is Second Generation Computer, IBM 1401 is a Second Generation Computer and
is the first computer to enter Nepal in 2028 BS for census. Government of Nepal
had brought this computer on rent and later purchased for data processing in
Bureau of Statistics. After this computer, another ICL 2950/10, a British
computer, was purchased by the fund of UNDP and UNFPA for the census of 2038 BS
is second computer in Nepal.
6. MSI stands for Medium Scale
Integrated Circuits, After the invention of IC chips the development of
computers plunged into next phase. Small Scale Integration and Medium Scale
Integration (SSI and MSI) were used in third generation of computers and Large
Scale Integration and Very Large Scale Integration (LSI and VLSI) are being
used in fourth generation of computers. People are now expecting ULSI (Ultra
Large Scale Integration) Circuits to be used for fifth generation computers.
7. The capacity of 3.5 inch floppy disk is 1.44 MB, Microfloppy disks (3.5 inch) if it
is high density (MF2HD) can store 1.44 MB and if it is low density (MF2DD), it
can store 720 KB. Mini Floppy disks (5.25 inch) if it is high density (MD2HD)
can store 1.2 MB and low density (MD2DD) stores 360 KB of data.
8. The first computer introduced in Nepal was IBM
1401, IBM 1401, a second generation computer was brought in Nepal by the
Government of Nepal paying One Lakh and twenty five thousands per month to use
in the census in 2028 B.S. Before this computer, Nepal was using a calculating
device called Facit for statistical tasks.
9. WAN stands for Wide Area Network,
There are three different classes of computer network namely, Local Area
Network (LAN) that covers a small geographical area such as a room, a building
or a compound; Metropolitan Area Network (MAN) that has a citywide coverage;
and Wide Area Network (WAN) that covers the whole globe or beyond the globe.
10. MICR stands for Magnetic Ink
Character Reader, Explanation: MICR (Magnetic Ink Character Reader) is kind of
scanner that can scan and identify the writing of magnetic ink. This device is
used in banks to verify signatures in Checks.
11. EBCDIC stands for Extended Binary Coded
Decimal Interchange Code, EBCDIC is an 8-bit binary code for larger IBMs
primarily mainframes in which each byte represent
one alphanumeric character or two decimal digits. 256 characters can be
coded using EBCDIC.
12. BCD is Binary Coded Decimal, BCD is a
binary coded notation in which each of the decimal digits is expressed as a
8-bit
binary numeral. For example in binary coded decimal
notation 12 is 0001 0010 as opposed to 1100 in pure binary.
13. ASCII stands for American Standard Code for
Information Interchange, ASCII is a code
which converts characters
letters, digits, punctuations and control
characters such as Alt, Tab etc – into numeral form. ASCII code is used to
represent data internally in micro-computers. ASCII
codes are 7 bits and can represent 0 to 127 and extended ASCII are 8
bits that represents 0 to 255.
14.EDSAC is first generation of computer:
IBM-1401, CDC-1604 is second generation computer. ICL-2900 is a fourth
generation
computer. EDSAC is important in the development of
computer since it was the first computer to use John von. Neumann’s
Stored Program Concept. It used 3000 vacuum tubes
and computers with vacuum tubes are of first generation computers.
15. Chief component of first generation computer
was Vacuum Tubes and Valves, Transistors were used for second generation
computers and integrated circuits in third
generation. First generation computers used vacuum tubes and valves as their
main
electronic component. Vacuum Tubes were invented by
Lee DeForest in 1908.
16. FORTRAN is Formula Translation, FORTRAN
(Formula Translation) is one of the earlier High Level programming languages
used
to write scientific applications. It was developed
by IBM in 1956.
17. EEPROM stand for Electrically Erasable
Programmable Read Only Memory There are three types of ROM namely, PROM, EPROM
and EEPROM. PROM can’t be reprogrammed, EPROM can be erased by exposing it in
high intensity ultraviolet light and EEPROM can be erased and reprogrammed
electrically. It is not needed to be removed from the computer to be modified.
18. Second Generation computers were developed during
1956 to 1965. Second generation computers used transistors as their
main electronic component. Transistor was invented
by Bell Lab Scientists John Burdeen, Walter Brattain and William Shockley
in 1947 and won the Nobel Prize in 1956 but it was
not used in computers till 1956. The second generation continued until the
implementation of IC chips invented by Jack Kilby in Texas Instruments in 1958.
19. The computer size was very large in First
Generation. It is obvious that computers developed with more power, eliability,
speed and smaller sizes due to the enhancement of
technology. First generation computers used 1000s of vacuum tubes that
required lot of space made them gigantic in size.
Single transistor could replace 1000 vacuum tubes and a single IC chip replaced
1000s of transistors made computers smaller and more speedy.
20. Microprocessors as switching devices are for
Fourth Generation computers. Microprocessors further revolutionized the development
of computers. Personal microcomputers were possible due to the microprocessors.
The first microprocessor called
Intel 4004 was developed by American Intel
Corporation in 1971. Microprocessors are used in the computers of fourth generation
computers.
