Computer Mouse

A computer mouse is a handheld hardware input device (also called Pointing device) that controls a cursor in a GUI and can move and select text, icons, files, and folders. For desktop computers, the mouse is placed on a flat surface such as a mouse pad or a desk and is placed in front of your computer.

Differences between analog and digital computers.

Analog Computer: An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence. Digital Computer: A digital computer is form computer that uses letters and numbers as inputs in processing and displays the result in monitors or other forms of output devices and can also store the output in memory to be used later. Following are some key differences between digital and analog computer
Analog Computer No. Digital Computer This type of computer uses continuously changeable aspects of physical phenomena. 1 This type of computer runs by turning on and off electricity which are digital signals. Electrical wave generated from pressure, temperature etc. such changeable data are used as input in analog computers…

Assembler

An Assembler is a type of computer program that interprets software programs written in assembly language into machine language, code and instructions that can be executed by a computer.
An assembler enables software and application developers to access, operate 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 services of an interpreter.

COMPILER & INTERPRETER

A compiler is a program that translates the entire source program written in some high-level programming language (such as Java) into machine code for some computer architecture (such as the Intel Pentium architecture).
A computer program which reads entire source code and outputs assembly code or executable code is called compiler.A program that translates software written in source code into instructions that a computer can understand Software used to translate the text that a programmer writes into a format the CPU can use.A piece of software that takes third-generation language code and translates it into a specific assembly code. Compilers can be quite complicated pieces of software. An Interpreter is a program that translates a source program written in some high-level programming language (such as BASIC) into machine code for some computer architecture (such as the Intel Pentium architecture) line by line.
A computer program which reads line by line source code and outputs as…
