CAHCET Computer Organization Question Paper
UNIT – I
1. What are number systems?
In mathematics, a ‘number system’ is a set of numbers, together with one or more operations, such as addition or multiplication. Examples of number systems include: natural numbers, integers, rational numbers, algebraic numbers, real numbers, complex numbers, p-adic numbers, surreal numbers, and hyperreal numbers
4. Why NAND & NOR are called universal gates?
Basic logic gates are AND, OR & NOT. Since any basic logic gates can be constructed using NAND & NOR gates, they are called as universal gates.
5. Give the advantages & disadvantages of of K-map.
Advantage: It is used to simplify Boolean function of upto 6 variables.
DisAdvantage:
i) Boolean function simplification is complicated when no. of variables exceeds 6.
ii) There is no systematic approach is used in K-map in BF simplification.
6. Write the purpose of Boolean algebra.
1. Express in algebraic form a truth table relationship between binary variables
2. Express in algebraic from the input-output relationship of logic diagrams
3. Find simpler circuits for the same function
8. What is K-Map?
A map method provides a simple, straightforward procedure for simplifying boolean expressions in pictorial representations. This map method is also known as the K-map or Karnaugh map
14.What is truth table?
The relationship between a function and it’s binary variables can be represented in a truth table.
15. Define Logic circuits
The manipulation of binary infromation is done by logic circuits is called gates or Logic gates
16. List out the names of logic gates
AND, OR, Inverter, Buffer, NAND, NOR, XOR, XNOR
17. List the differences between AND & NAND gates.
AND gates gives output is 1 if input A and input B are both equal to 1 otherwise the output is 0. NAND gate is a complement of AND function
18. What is computer organization?
Computer organization is concerned with the way the hardware components operate and the way they are concerned together to form the computer system.
19. Define signal.
Binary information is represented in digital computers by physical quantities called signals
20. What is combinational circuits?
A combinational circuit is a connected arrangement of logic gates with a set of inputs and outputs.
21.What is 9’s and 10’s complement?
Given a number N in base r having n digits, the (r-1)’s complement of N is defined as (rn-1)-N.F or decimal number r=10 and r-1=9, so the 9’s complement of N is (10n-1)-N.
UNIT – II
1. What is Encoder?
An encoder is a digital circuit that performs the inverse operation of a decoder. an encoder has 2n input lines and n output lines
2. What is Decoder?
A decoder is a combinational circuit that converts binary information from the n coded inputs to a maximum of 2n unique outputs
3. Differentiate between encoder and decoder.
Encoder is the reverse of a decoder. In a decoder it has n input lines and 2 n output lines, but in an encoder it has 2 n input lines and n output lines.
4. Differentiate combinational and sequential circuits.
A combinational circuit is the binary relationship between the n input and the m output variables combinations. A sequential circuit is an interconnection of flip-flops and gates, but when used with overall circuit is called sequential circuit.
