Does a Computer understand our language? What is Software? What is Hardware? What is Humanware?

Do you think that computer can understand our language? If your answer is yes then you are wrong.

Computer cannot understand our language.  A computer follows the instructions given by the programmer to perform a specific job. To perform a particular task, programmer prepares a sequence of instructions known as Programme. A computer understands only one language that is binary language. Binary language is contains with only 1‟s and 0‟s. Binary language is also known as Low level language and Machine level language.

To communicate with the computers, we need some languages. These are computer languages.

There are mainly three different languages with the help of which we can develop computer programs. And they are –

• Machine Level language
• Assembly Level Language and
• High Level Language

What is Programming Language? 

A computer follows the instructions given by the programmer to perform a specific job. To perform a particular task, programmer prepares a sequence of instructions known as Program. A computer understands only one language that is binary language. Binary language is contains with only 1‟s and 0‟s. Binary language is also known as Low level language and Machine level language.

What are the classifications of Programming Language?

1. First generation language (1GLs) – Machine Language

2. Second generation language (2GLs) – Assembly Language

3. Third generation language (3GLs) – High Level Language

4. Forth generation language (4GLs)

5. GUI Based language

What is software?

Software represents the set of programs that govern the operation of a computer system and make the hardware run. Software can be classified into two categories:

1. System Software 

2. Application Software

The software that controls the internal computer operations is called System Software. E.g. Windows XP, Windows 7 etc. On the other hand An Application Software is the set of programs necessary to carry out operations for a specified application. E.g. MS-Word, MS-Excel etc. What is Operating System? Ans: - An operating system is a program which acts as an interface between a user and the hardware. OS is just like our secretary. An OS is an important component of a computer system which controls all other components of the computer system. 

Types or Classifications of OS:

1. Single User OS

2. Multi-program OS

3. Time Sharing OS

4. Real Time OS

5. Multiprocessing OS

Functions of an Operating System:

1. Processor Management

2. Input/output Management

3. File Management

4. Priority Management

5. Switch between programs

6. Error detection
