Task 1:
For buying a personal computer the basic and important features are given below. At first
Random Access Memory (RAM) is the main memory of a computer. It improves the speed of
the computer. It should be of 8Gigabyte for better performance. The hard disk drive should be of
minimum 1Terabyte (TB). If it is of 2Tb, it would be great but having 1Tb storage is okay.
Processor is the main function that controls the computer. It would be great if the processor is i5
with 8th generation. i5 is far better than i3 and this provides much speed than the 7th generation.
Task 2:
The components of a software system are Network services, hardware level operating system,
logical level of operating system, Graphics engine and so on.
Role of network services is it provides a data storage, manipulation and so other things on the
internet.
Role of hardware level operating system is that hides the complexities of the processor. This
includes managing hardware resources like memory, data storage and so on.
Role of logical level operating system is that it provides higher functions like, internet access,
file management.
Role of Graphics engine permits the software framework to build games. They provides features
from animation to artificial intelligence.
Task 3:
The statement implies that each of them has the same facility or speed. But the main difference is
they are built or developed in a same manner but their appearance, flexibility.

Task 4:
A conceptual model that states the behavior, structure of an architecture is known as system
architecture. As well as it is defines how a process will be executed.
Task 5:
Task 6:
(5278)10= 5*103+2*102+7*101+8*100
Task 7:
The range will be 0-17.
Task 8:
The binary addition is 10101 + 1110= 100011
The binary multiplication is 10101 * 1110= 100100110
Task 9:
For converting decimal to hexadecimal it will be the best way to convert the decimal into binary
and then converting the binary to hexadecimal.
(12345)10 = (11000000111001)2 = (3039)16
From the above solution the binary of 12345 is also provided.
(12345)10 = (11000000111001)2
Task 10:
(212)10 = (324)8

Task 11:
(117)10= (75)16
Task 12:
(12345)10 = (11000000111001)2
Task 13:
(27.625)10= (11011)2
(4192.37761)10= (1000001100000)2
Task 14:
(0.1001001)10= 0
(1100101.1)10= (101)2
Task 15:
Motion vector captures the differences between video frames. After that DCT (Discrete Consine
Transform) is used to convert information. After that quantization is put on for DCT coefficients.
Then Huffman encoding uses small codes to demonstrate common values.
Task 16:
1010100= 84, 1101000=104, 1101001=105, 1110011=115, 0100000=32
1101001=105, 1110011= 115, 0100000=32, 1000101=69, 1000001=65,
1010011=83, 1011001=89, 0100001=33
