![An OPERATING SYSTEM is a program, which acts as an
interface between a user and the hardware.[i,e., all computer
resources].
The primary goal of an operating system is thus to make the
computer system convenient to use and secondary goal is to
use computer hardware in an efficient manner.

![As programmers prefers to write their programs in one of the HIGH-LEVEL
LANGUAGES(HLLs) because it is much easier to code in such languages. However, the
computer does not understand any language other than its own machine language
(binary language), therefore,
It becomes necessary to process a HLL program so as to make it understandable to the
computer, the system programs which perform this very job are language processor.
The language processors are given below :-
1. Assembler
2. Interpreter
3. Compiler
Language Processor [translator]](https://image.slidesharecdn.com/wovenfibers-250115233858-12b6fd2a/85/Woven-fiberssssssssssssssssssssssss-pptx-6-320.jpg)
![• Assembler
This language processor converts the program written in assembly
language into machine language.
• Interpreter
This language processor converts a HLL program into machine language
by converting and executing it line by line .
• compiler
It also converts HLL program into machine language but the conversion manner is
different.
It converts the entire HLL program in one go, and reports all the error of the
programalong with the line numbers

- 1. Types of software By:- HARKARAN VEER SINGH 9C,roll no. 10
- 2. A computer system is consist of HARDWARE and SOFTWARE for its functioning HARDWARE: Hardware represents the physical components of a computer i.e, the components which can be seen and touched. SOFTWARE: Software represents the program which govern the operations of a computer and make the hardware run. Types of software
- 3. Software can broadly be classified into two categories;- ● System software. ● Application software. SYSTEM SOFTWARE refer to the programs which controls the internal operations and make the best use of hardware. APPLICATION SOFTWARE refers to the set of programs which controls the necessary operations for a specified application Software
- 4. System software controls the internal operations and make the best use of hardware reading data from input devices, transmitting processed information to the output devices , checking system components , etc. System software can further be divided into three categories ● Operating system. ● Language processor. ● Utility software. System software

- 8. Utilities are those application programs that the computers by performing house-keeping functions like backing up disk or scanning/cleaning virus etc. Utility Software(Utilities)
- 9. 1. Disk/Folder/File management Software. This utility software is a program or simply File manager. Traditional file management software lets you create a new file, and save a file. 2. Antivirus Software(virus scanner/cleaner). This utility program ensures virus free work environment. 3. Encryption/Decryption Software. Encryption: Is the conversion of electronic data into another form , encrypted form called Ciphertext Utility Software
