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

Question # 1

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 # 2

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 # 3

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 # 4

Differentiate Between Linking and Loader.

Ans 1: Linking :The Linker is a program the combine the object program with additional object files that may be needed for the program to execute and save the final machine language program as an executable file on disk. The linker combine different library files to the object file and produces an executable file with exe extension
Ans 2: Loding : A loader takes an executable file and copies its section into memory. Then it produces a process control block to control program execution. Finally, it starts executing the code , usually by jumping to its main address .

Question # 5

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 # 6

Described the concept of linker .

Ans 1: The Linker is a program the combine the object program with additional object files that may be needed for the program to execute and save the final machine language program as an executable file on disk. In Turbo C++ , the linker can be invoked by selecting Complile | Link from the menu bar. The linker combine different library files to the object file and produces an executable file with extension

Question # 7

Who is Programmer?

Ans 1: A computer is a device that follow the instructions given to it. A person who well define set of instructions to the computer is called Programmer .

Question # 8

What are programming Languages?

Ans 1: Programming Languages : The language which are used to write computer programs are called Programming language.
Categories : There are two broad categories of programming languages
1. Low Level Languages
2. High Level Languages

Question # 9

How program logic is implemented in un-structured programming languages?

Ans 1: In un-structured programming languages, the entire logic of the program is implemented in a single module (function), which cause the program error prone, difficult ti understand, modify and debug.

Question # 10

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.
