What is a computer?
A computer is an electronic computing device that processes the data input by the users to give meaningful outputs.
Data-The input that we provide to the computer is known as data.
Data can be in the form of numbers, alphabets,pictures,sound etc.
Information-The output that we get after the data is processed to
give it more meaning is referred to as information.
Example:Ram scored higher percentage than Shyam.
Process-Process refers to any processing done on the data such as
applying mathematical or logical operations on the data inputed.
Processor-Computer is a computing device which gives meaningful outputs
by processing the data inputed.Hence, it is known as processor.
Command-A set of meaningful and complete instructions are given to the computer to process data.Each instruction given to the computer is known as command.
Program-Computer processes data based on a set of instructions.
The set of instructions together is known as a program.
Software-An integrated set of programs is known as software.
High level languages-High level language refers to any programming language used by an individual to develop a program without giving regard to any computer hardware requirements.
Translators-Translators are a set of programs used to translate different levels of languages into the computer understandable language.Translators are of 3 types namely Assembler,Compiler and Interpreter.
Compiler-Compiler is a program that translates source code written by the user in high level languages into a lower level language or assembly language.
Assembler-Assembler is a program that translates assembly language into machine language.Assembly language uses a mnemonic or object code to represent each lower level machine operation.
Interpreter-An interpreter is a program that executes other programs written in programming scripting language directly
analyzing each and every line and executing it line by line.
Programmers-Programmers refers to those individuals or group of people who write programs to develop a software.
Application software-Any software developed for a specific application meant to serve a distinct purpose is known as application software.Example:Tally is an application software used only to perform accounting operations.
System software-Any software developed to interpret user defined instructions to the computer and produce the needed information
is known as system software.Example:Operating system software such as windows is a system software
Memory-The capability of the computer to remember or register data given to it is known as memory.
