Answers
Answer:

Example:- CPU, Keyboard, Monitor, Mouse, UPS
Software is a Collection of Programs. Example:- MS Office
2. Two types of Software
i. System Software
ii. Application Software
3.
a) Operating System:- An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs.
b) Language Translator:- Language translator is a program which is used to translate instructions that are written in the source code to object code i.e. from high-level language or assembly language into machine language.
c) Utility Programs:- A utility program is a small program that does something useful.
As operating systems have improved, utility programs that once had to be bought separately from the main operating system are now included, so now appear as an integral part of it.
d) Application Software:- Application Software is a program that does real work for the user. It is mostly created to perform a specific task for a user.
Application Software acts as a mediator between the end-user and System Software. It is also known as an application package. This type of software is written using a high-level language like C, Java, VB. Net, etc. It is a user-specific and is designed to meet the requirements of the user.
e) General Purpose Package:- These are application packages that are in common use and may be supplied with desktop computer systems. GPPs are widespread because the data objects contained in each package fall into the categories of text, number, data and graphics; these are the most commonly used data type in the field of computing.

Ans 3 -
(a) operating system - a computer program that organizes a number of other programs at the same time
(b) language translator - A translator or programming language processor is a generic term that can refer to anything that converts code from one computer language into another. A program written in high-level language is called source program.
(c) utility programs - Utility software is software designed to help to analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users.
(d) application software - Application software is a program or group of programs designed for end-users. Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, an email client, a media player, a file viewer, simulators, a console game, or a photo editor
(e) General purpose package - GPP's are commercially available, fully tested software or Application's Packages that have been created to help users solve a range of problems.
