12th Class Computer Science Chapter 8 Short Questions with Answers Online Preparation

Question # 1

What is the difference between machine language and assembly language ?

Ans 1: Machine Language :Machine language is the native language of the computer. The computer does not need any translator to understand this language. Programs written in any other language must be converted to machine language so that the computer can understand them. Every machine language instruction consists of string of binary 0s and 1s.
Ans 2: Assembly Language :Assembly level language is a set of codes that can run directly on the computer's processor. This type of language is most appropriate in writing operating systems and maintaining desktop applications. With the assembly level language it is easier for a programmer to define commands. It is easier to understand and use as compared to machine language.

Question # 2

Define the term Debug.

Ans 1: Debugging is the routine process of locating and removing program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications.

Question # 3

What is Syntax ?

Ans 1: Syntax Errors : A Syntax error occurs when the program violates one or more grammar rule of C language.
The compiler detects these errors as it attempts to translate the program. If a C statement has syntax error, it cannot be translated and the program could not be executed.
Causes : There can be many causes of syntax errors:
1. Missing terminator I.e the semicolon using a variable without declaration , missing any of the delimiters I.e, {or}etc
2. A syntax error may also occur when an invalid equation is entered into a calculator.

Question # 4

Write two Characteristics of C-language .

Ans 1: 1) This is English like language, hence rare close to human language and far from the machine language and very easy to learn.
2) This described a well defined way of writing programs.

Question # 5

What is Machine Language?

Ans 1: Machine language is the native language of the computer. The computer does not need any translator to understand this language. Programs written in any other language must be converted to machine language so that the computer can understand them . Every machine language instruction consist of string of binary 0s and 1s .

Question # 6

Differentiate between Logical Errors and Syntax Errors.

Ans 1: Logical Errors : Logical errors when a program follows a faculty algorithm. The compiler cannot detect logical errors; therefor no error message is reported from the compiler . Moreover, these errors don't cause the program to be crashed ,that's why these are very difficult to detect. One can recognize logical errors by just looking at the wrong output of the program. Logical errors can only be detected by through testing of the program.
Ans 2: Syntax Errors: A Syntax error occurs when the program violates one or more grammar rule of C language.The compiler detects these errors as it attempts to translate the program. If a C statement has syntax error, it cannot be translated and the program could not be executed.

Question # 7

Define Low Level Language ?

Ans 1: Low Level Language : A low level language is a programming language that deals with a computers hardware components and constraints. It has no (or only a minute level of) abstraction in reference to a computer and works to manage a computers operational semantics. A low-level language may also be referred to as a computer native language.
Categories: There are two broad categories of low level language.
1. Machine Languages
2. Assembly Languages

Question # 8

What is Object Code?

Ans 1: Object code is a set of instruction codes that is understood by a computer at the lowest hardware level. Object code is usually produced by a compiler that reads some higher level computer language . Source instruction amd translate into equivalent machine language instructions.

Question # 9

What are preprocessor directives?

Ans 1: Preprocessor directives are commands that give instruction to the C preprocessor. The preprocessor is a program that modifies the program .(Source program) prior to its compilation. A preprocessor directive always begins with the symbole (#). In the above program, include is preprocessor directives.

Question # 10

What is Linking?

Ans 1: Link is the Process in which the object file produced by the compiler is linked to many other library files by the linker .
