Computer basics: organization of a computer, characteristics of a
computer, Central Processing Unit (CPU), types of instructions in CPU,
input/output devices, computer memory, primary memory and secondary memory,
memory organization, backup devices.
Data representation: representation
of characters, integers and fractions, binary and hexadecimal representations.
Binary arithmetic: addition, subtraction, division, multiplication,
signed arithmetic and two’s complement arithmetic, floating point
representation of numbers, normalized floating point representations.
Foundations: Boolean algebra, truth tables and Venn diagrams.
Computer architecture: block structure of computers, communication
between processor and memory, communication between processor and I/O devices,
interrupts, multiprogramming, and virtual memory.
Computer languages: assembly language and characteristics of high-level
languages.
Operating System basics: Multiprogramming and timesharing operating
systems.
Programming using a subset of C: The candidate will not be required
to write programs and there will not be any questions on syntax.
But candidates should be able to read and understand programs involving
the following:
the assignment statement, blocks, the input-output statements (scanf and
printf), relational and arithmetic operators, conditional statements and
iterations.
Data types, expression evaluation, precedence rules, type conversions,
sequential structure, selective structure, repetitive structure, functions
(including recursion), arrays, pointers, structures and unions, operations on
bits, file processing, pre-processor. The syntax assumed will be that of ANSI C.
Approximately 20% of the questions will test the candidate's knowledge of the
syntactical structure of 'C'. The remaining questions will test the candidate’s
working knowledge and understanding of the 'C'.
