ASSIGNMENT
DRIVE FALL 2016
PROGRAM BACHELOR OF BUSINESS ADMINISTRATION (BBA)
SEMESTER I
SUBJECT CODE & NAME BBA110 - COMPUTER FUNDAMENTALS
BK ID B1501
CREDITS 2
MARKS 30
Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Question.1. With a neat diagram explain the architecture of a
computer.
Answer:Incomputerengineering,computerarchitectureisaset of rules and methods that describe
the functionality, organization, and implementation of computer systems. Some definitions of
architecture defineitasdescribingthe capabilitiesandprogrammingmodel of a computer but not a
particular implementation. In other definitions computer architecture involves instruction set
architecture design, microarchitecture design,
Question.2. a. What is main memory? What are the types of main
memory?
Answer:Incomputing,memoryreferstothe computer hardware devices used to store information
for immediate use in a computer; it is synonymous with the term "primary storage". Computer
memoryoperatesata highspeed,forexample random-accessmemory (RAM), as a distinction from
storage that provides slow-to-access program and data storage but offers higher capacities. If
needed, contents of the computer memory can be transferred to secondary storage, through a
memory management technique called "virtual
b. What is secondary memory? Give examples.

2. Answer:Secondarymemory(or secondary storage) is the slowest and cheapest form of memory. It
cannot be processeddirectlybythe CPU.Itmust firstbe copied into primary storage (also known as
RAM).
Secondary memory devices include magnetic disks like hard drives and floppy disks; optical disks
such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.
Secondary storage is used as a cheaper alternative
Question.3. Write short notes on the following:
a. Decimal Number System
Answer:Decimal number system, also called Hindu-Arabic, or Arabic, number system, in
mathematics, positional numeral system employing 10 as the base and requiring 10 different
numerals, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. It also requires a dot (decimal point) to represent
decimal fractions. In this scheme, the numerals used in denoting a number take different place
values depending upon position. In a base-10 system the number 543.21 represents the sum (5 ×
102) + (4 × 101) + (3 × 100) + (2 × 10−1) + (1 × 10−2). See numerals and numeral systems.
This number system, with its associated arithmetic algorithms, has furnished the basis for the
development of Western commerce and science since its introduction to the West in the 12th
century ad.
b. Binary Number System
Answer:Inmathematicsanddigital electronics,abinarynumberisanumberexpressedin the binary
numeral system or base-2 numeral system which represents numeric values using two different
symbols:typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2.
Because of its straightforward implementation in digital electronic circuitry using logic gates, the
binarysystemisusedinternallybyalmostall moderncomputersand computer-based devices. Each
digit is referred to as a bit.
c. Octal Number System
Answer:Binary is also easily converted to the octal numeral system, since octal uses a radix of 8,
which is a power of two (namely, 23, so it takes exactly three binary digits to represent an octal

3. digit).The correspondence betweenoctal andbinarynumeralsisthe same asfor the firsteightdigits
of hexadecimal in the table above.
d. Hexadecimal Number System
Answer:Binarymay be converted to and from hexadecimal somewhat more easily. This is because
the radix of the hexadecimal system (16) is a power of the radix of the binary system (2). More
specifically,16= 24, so it takesfourdigitsof binaryto representone digit of hexadecimal, as shown
in the table to the right.
