Different Types of Software with Examples

There are two main types of software - system software and application software. Let us discuss these types of software in detail with examples of each.

System Software

System software is a set of programs used to implement certain functions in a computer system. System software controls the overall operations and components of a computer system.
We can say that system software is the base on which application programs are executed. System software provides an interface between user and computer. Users use this interface to interact with the computer and perform different jobs on computer. Operating systems like Windows, Linux and Unix are the main example of system software. Similarly device drivers software are also examples of system software.

Examples of system software

Examples of system software are as follows:

• Operating Systems

Operating system is software to control overall operations and components of a computer system. e.g., Windows, UNIX, Linux and Dos etc.

• Utility Programs

Utility program is used to solve a particular problem of software or hardware, for example, Antivirus program, disk scanner and File Viewer etc.

• Device Drivers

Device driver is software that permits a computer system to communicate with a device. e.g., device driver software for a modem comes with it on CD. We have to install device driver before using a device.

• Language Processors

Language processor is software that converts a source program into object program. For example C- compiler converts a program written in C language into object program (machine code).

Application Software

Application software is a program needed to perform various applications on the computer by the user. It helps a computer user to solve specific problems like to prepare letters and other documents, to create pictures and advertisements, to perform large calculations quickly etc.
The application software runs on top of the operating system software.
Examples of application software are as follows:

i. Word Processing

Word processing software is used to produce letters, applications and other documents. Microsoft Word is the most popular application software used for word processing.

ii. Spreadsheets

Spreadsheet program is used to create electronic worksheets. These worksheets are used to perform calculations on large amounts of data quickly and automatically. Microsoft Excel is a popular spreadsheet program.

iii. Databases

Database software is used to record data of an organization on computer in compact and efficient form. MS Access, MS SQL Server and Oracle are examples of database software.

iv. Graphics

Graphics software is used to produce advertisements, posters and pictures etc. for example CorelDraw and Photoshop are popular graphics software.

v. Communication

Communications software is used to communicate with different people using Internet, e.g., MSN Messenger, yahoo messenger and Internet Explorer.

This is all about two main types of software used in computers.

Define Data and Information With Examples

DATA Data is the collection of raw facts and figures. Actually data is unprocessed, that is why data is called collection of raw facts and figures. Define Data and Information with Examples We collect data from different resources. After collection, data is entered into computer for processing. Data may be collection of words, numbers, pictures, or sounds etc. Examples of Data 1) Student Data on Admission Forms When students get admission in a college. They fill admission form. This form contains raw facts (data of student) like name, father’s name, address of student, obtained marks, photo graph etc. 2) Data of Citizens During census, data of all citizens is collected. The staff will go house to house and collect data about citizens like number of persons living in a home, either they are literate or illiterate, number of children, data of each child, cast, religion, Computerized national Identity Card number, address, how many rooms and other facilities in the

MMC stands for multimedia card. SD stands for secure digital card. System Bus is used to connect main components of a computer such as cpu and main memory. A Port is an interface or a point of attachments. POS stands for Point Of Sale terminal. ATM stands for Automated Teller Machine. PIN stands for Personal identification number. Kbps stands for kilobits per second. Mbps stands for megabits per second. A port that transmits one bit at a time is called Serial Port. A type of port that transmits many bits at a time is called Parallel Port. LPT stands for Line Printer. Examples of system software are Operating System, Utility Programs and Device Drivers. Examples of operating systems are DOS, Windows, Unix and Linux. Examples of Utility programs are File Manager, Image Viewer, Disk Scanner and File Compressor. Software used to detect and remove viruses is called Antivirus . Examples of antivirus programs are Mcaffee, Avast,

Advantages and Disadvantages of Ring Network Topology

Topic: Advantages and Disadvantages of Ring Network Topology alongwith detailed working of Ring topology What Do You Mean by Ring Topology? In Ring topology, each computer is connected to the next computer such that last computer is connected to the first. Every computer is connected to next computer in the ring. Each computer retransmits what it receives from the previous computer. Suppose, computer A needs to send data to computer D. Now the computer A sends data to computer B. As computer B is not the destination computer, so it will retransmit data to computer C. Finally, Computer C will transfer data to computer D, the destination computer. When a node sends a message, the message is processed by each computer in the ring. If a computer is not the destination node, it will pass the message to the next node, until the message arrives at its destination. Advantages of Ring Network Topology 1. It is relatively less expensive than a star topology network. 2. In a Rin
