Intro to programming language-ICT

Question 1

What is a programming language?

Answer 1

These are sets of instructions that tell the computer what to do.

Question 2

List 2 types of computer programs

Answer 2

low level language and high level language

Question 3

What are translators?

Answer 3

A translator is a program that converts source code into machine code

Question 4

List 3 types of translators

Answer 4

compiler, interpreter, and assembler

Question 5

List 8 examples of computer high-level programs

Answer 5

BASIC
FORTRAN
PASCAL
Logo
COBOL
C++
D-base
ALGOrithmetic

Question 6

What is the syntax?

Answer 6

Syntax is a set of grammatical rules used in computer programming

Question 7

How do computers understand humans?

Answer 7

Computers understand humans through the use of translators to convert High Level Languages to Low Level Languages

Question 8

What is another name for high level languages and machine language

Answer 8

High level languages are called source code
Machine language is called object code

Question 9

Why do they call HLLs human-oriented?

Answer 9

HLLs are human-oriented because they are understood by humans.

Question 10

Define Interpreters, Compilers and Assemblers.

Answer 10

Interpreters are translators that convert HLL to machine language line by line or one instruction before the other.
Compilers are translators that convert HLL to Machine language all at once.
Assemblers are translators that convert Assembly language to Machine language.

A translators is a program that converts one language form to another.

Question 11

List the types of system software

Answer 11

Operating system
Executive programs
Translators
Bootstrap loader
Utility programs

Question 12

What is a computer language?

Answer 12

This is a system of instructions and commands that the computer understands and executes.

Question 13

What is a program?

Answer 13

This is a set of instructions that enable the computer to perform given tasks.

Question 14

What is programming?

Answer 14

This is the act of giving the computer codes to perform a specific task

Question 15

How many types of computer languages are there and name them

Answer 15

There are two types of computer languages, namely:
Low Level Language
High Level Language

Question 16

Briefly define machine language

Answer 16

This language is understood by computers which cannot be understood or utilised by humans, it consists of binary digits, 0’s and 1’s. It is very fast to execute.

Question 17

Briefly define assembly language

Answer 17

Unlike machine language the instructions and variables have names instead of numbers. It is translated into machine language with an assembler. It consists of letters, mnemonics and symbols.

Question 18

Briefly define HLLs

Answer 18

High Level Languages are human understandable languages. It allows programmers to write programs that aren’t dependent on the CPU design.
Examples: fortran, BASIC, COBOL, C, C++, Java, Pascal

Question 19

What are the two divisions of LLLs?

Answer 19

The two divisions of LLLs are assembly language and machine language.
Assembly language is made up of symbols, letters, and mnemonics. A machine language consists of 0’s and 1’s.

Question 20

Briefly define the two divisions of LLLs

Answer 20

Assembly language is made up of symbols, letters, and mnemonics. A machine language consists of 0’s and 1’s.

Question 21

Differentiate between HLLs and LLLs

Answer 21

this is supposed to be in a tabular form but there isn’t a way to add a table
HLLs are human understandable languages while LLLs are machine understandable languages
HLLs allow programmers to write programs that aren’t dependednt on CPU design while LLLs programs are machine dependent.
HLLs use human languages like French and English while LLLs use machine language(0’s and 1’s)
HLL: programs written in HLL need to be translated into machine language while codes written in LLL are directly understood by the computer.
