software

Question 1

_______ level languages are close to human language.

Answer 1

High

Question 2

High level languages

Answer 2

independent of platform(works on different machines)

Question 3

Low level languages

Answer 3

use machine specific functions; works directly on the CPU

Question 4

______ level languages can refer to a machine code, the _________ instructions that a computer understands, or _______ language that needs to be translated into machine code.

Answer 4

Low, binary, assembly

Question 5

examples of high level language

Answer 5

JAVA, Python, VB

Question 6

_________ level language is easier to understand than _________ level language.

Answer 6

High, Low

Question 7

Which one is used more commonly by programmers: High or Low level language?

Answer 7

High

Question 8

Why write code in a Low level language?

Answer 8

direct access to the processor; uses less memory; executes instructions faster

Question 9

Compilers

Answer 9

translates the whole program at once from HIGH level language to MACHINE code; creates an exe file; list of errors created; optimizes source code

Question 10

What happens when an error is detected within a compiler?

Answer 10

an error report is produced instead of a compiled program.

Question 11

Interpreters

Answer 11

executes a high-level program one statement at a time; no executable file of machine is produced; easier to debug

Question 12

What happens when an error is detected within an interpreter?

Answer 12

identifies error as soon as it finds one and stops; error must be fixed to continue

Question 13

An _________ often used when a program is being developed.

Answer 13

interpreter

Question 14

A _________ program is usually distributed for general use.

Answer 14

compiled

Question 15

For __________, one high-level language statement can be translated into several machine code instructions.

Answer 15

Compiler

Question 16

For __________, one high-level language program statement may require several machine code instructions to be executed.

Answer 16

Interpreter

Question 17

_________ run without the the compiler.

Answer 17

Compiled

Question 18

_________ cannot be run without the interpreter.

Answer 18

Interpreted

Question 19

disadvantages of High level languages

Answer 19

programs can be larger; can take longer to execute; may not be able to make use of a special hardware

Question 20

disadvantages of Low level languages

Answer 20

takes longer time to write and debug programs; programs are more difficult to understand

Question 21

advantages of High level languages

Answer 21

easier to read, write, and understand programs; quicker to write; easier/quicker to debug; easier to maintain programs in use

Question 22

advantages of Low level languages

Answer 22

can make use of special hardware; includes special machine-dependent instructions; can write code that doesn’t take up much space in primary memory; can write code that performs a task very quickly
