Assembler
- Assembler is the type of computer program that interprets software programs written in assembly language into machine language, code, and instructions that can be executed by the computer.
- It enables software and application developers to access operations and manage a computer’s hardware architecture and components.
- An assembler is sometimes referred to as the compiler of assembly language. It also provides the service of an interpreter.
Text Editor
- The term editor is commonly used to refer to a text editor.
- It is a software program that allows users to create or manipulate plain text computer files.
- It is often used in the field of computer programming.
Compiler
- A program that converts another program from some source language ( or HLL )to machine language (object code). The compiler goes away during execution.
- Some compilers output assembly language which is then converted to machine language by a separate assembler.
- It is distinguished from an assembler by the fact that each input statement, in general, corresponds to more than one machine instruction.

Interpreter
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program.
Algorithms
In computer science, an algorithm is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of problems or to perform a computation. Algorithms are unambiguous specifications for performing calculations, data processing, automated reasoning, and other tasks.
Example:
Step 1: Start;
Step 2: int a=5,b=6,c;
Step 3: c=a+b;
Step 4: Printf c;
Step 5: stop
Flowcharts
A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.
Example:
Pseudocode
- Pseudocode is an informal program description that does not contain code syntax or underlying technology considerations. Pseudocode summarizes the steps of a program or flow but excludes underlying details.
- It is widely chosen because:
– Easy to read and write.
– It allows the programmer to concentrate on the logic of the problem.
– Structured in the English language.
