Test Number 11/95

Q: Which of the following is not a data type?
A. Symbolic Data
B. Alphanumeric Data
C. Numeric Data
D. Alphabetic Data
Solution: Data types are of three basic types: Numeric, Alphabetic and Alphanumeric. Numeric Data consists of only numbers.
Alphabetic Data consists of only letters and a blank character and alphanumeric data consists of symbols.
Q: *@Ac# is a type of ________________ data.
A. Symbolic
B. Alphanumeric
C. Alphabetic
D. Numeric
Solution: Alphanumeric data consists of symbols. Alphanumeric data may be a letter, either in uppercase or lowercase or some special symbols like #,^,*,(, etc.
Q: Which of the following is not a valid representation in bits?
A. 8-bit
B. 24-bit
C. 32-bit
D. 64-bit
Solution: There are no criteria like the 24-bit representation of numbers. Numbers can be written in 8-bit, 16-bit, 32-bit and 64-bit as per the IEEE format.
Q: What are the entities whose values can be changed called?
A. Constants
B. Variables
C. Modules
D. Tokens
Solution: Variables are the data entities whose values can be changed. Constants have a fixed value. Tokens are the words which are easily identified by the compiler.
Q: Which of the following is not a basic data type in C language?
A. float
B. int
C. real
D. char
Solution: There are 5 basic data types in C language: int, char, float, double, void.
Int is for the representation of integers, char is for strings and characters, float and double are for floating point numbers whereas void is a valueless special data type.
Q: BOOLEAN is a type of data type which basically gives a tautology or fallacy.
A. True
B. False
C. none
D. 0
Solution: A Boolean representation is for giving logical values. It returns either true or false. If a result gives a truth value, it is called tautology whereas if it returns a false term, it is referred to as fallacy.
Q: What does FORTRAN stands for?
A. Formula Transfer
B. Formula Transformation

D. Format Transformation
Solution: FORTRAN is a type of computer language. It was developed for solving mathematical and scientific problems. It is very commonly used among the scientific community.
Q: The program written by the programmer in high level language is called ________
A. Object Program
B. Source Program
C. Assembled Program
D. Compiled Program
Solution: The program written by the programmer is called a source program. The program generated by the compiler after compilation is called an object program. The object program is in machine language.
Q: A standardized language used for commercial applications.
A. C
B. Java
C. COBOL
D. FORTRAN
Solution: COBOL is a language used in business and commercial applications. It stands for Common Business Oriented Language. It is imperative, procedural as well as object oriented language.
Q: ____________ define how the locations can be used.
A. Data types
B. Attributes
C. Links
D. Data Objects
Solution: Attributes can determine how any location can be used. Attributes can be type, name, component, etc. Data objects are the variables and constants in a program.
