Addition of element is known as INSERT operation, also known as enqueuing. It is done using rear terminal position, i.e. tail end. Removal of the element is known as DELETE operation, also known as dequeuing.

The major operations are:

1. Traversal

2. Insertion

3. Deletion

4. Searching

Queue is a first-in, first-out (FIFO) data structure, i.e. the element added first to the queue will be the one to be removed first. Elements are always added to the rear of the queue and removed from the front of the queue.

Carrying of goods and people from one place to another is called transport.

Golden Quadrilateral Superhighway

The modes of transport which cany people, goods and services on land come under surface transport. It is mainly divided into roadways, railways and pipelines.

2. FIFO: First-In First-Out

Two hardware requirements for multimedia are as follows: 

1. The CPU for a multimedia computer should be Pentium IV or other advanced chips.

Roadways and Railways.

Following are the modern means of communication: 

Internet: Internet began in 1969. During initial days, internet was used for exchange of data over a limited area. Beginning of e-mail in 1972 brought a revolution in communication. Any information can be sent to any part of the world within a few seconds through e-mail. It enables to do video conferencing. Videoconferencing saves time and money and enables us to communicate through audio-visual medium.

Telephone: Telephone is an important tool of communication. It was invented by Graham Bell. There has been continuous improvement in telephones.Telephone facilitates conversation between two people who are sitting at distant places. Beginning of STD and ISD facilities in telephone helped in directly dialing numbers to any place within the country or to any country in the world. Use of STD and ISD involves using STD or ISD code of a place followed by dialing the number.

Mobile Phone: Invention of mobile phone brought a revolution in the field of telephony. Mobile phones enable us to directly talk to a person (who is using a mobile phone). High speed 3G and 4G internet services are available through mobile phones. You can do video calling through mobile phone. Mobile applications have further improved communication. Technology in this field is developing at a rapid pace on a daily basis.

Rail transport is suffering from many drawbacks. A large number of people resort to ticketless travel. Many people damage the railways’ property and commit theft and robbery. Many passengers unnecessarily pull the chain to stop the train without schedule. This results in heavy losses to the railways.
