Nowadays, we can watch live telecasts of music concerts or cricket matches in TV. TV channels use _______ to transmit their programs with the help of computers. 

Detailed Solution for Olympiad Test Level 2: Introduction to Internet - 1 - Question 1

The TV channels use satellites to transmit their programs with the help of computers. This process involves the following steps:
1. Live Telecasts: TV channels have the capability to broadcast live events such as music concerts or cricket matches in real-time.
2. Transmission Technology: To transmit these live telecasts, TV channels use various technologies, one of which is satellite transmission.
3. Satellites: Satellites are placed in geostationary orbit around the Earth, enabling them to stay fixed at a specific position relative to the Earth's surface. These satellites act as relay stations in the sky, receiving broadcast signals from the TV stations and retransmitting them to the viewers' homes.
4. Transmitting Signals: TV channels transmit their programs in the form of signals that are received by the satellites. The signals are then amplified and retransmitted back to Earth.
5. Receiving Stations: Viewers receive the transmitted signals through their TV antennas or satellite dishes. These receiving stations capture the signals and convert them into audio and video signals that can be displayed on the viewers' TV screens.
6. Computers: Computers play a crucial role in the transmission process. TV channels use computers to encode and compress the audio and video signals before transmitting them to the satellites. Computers also aid in the decoding and decompressing of the signals at the receiving end.
7. Advantages of Satellite Transmission: The use of satellites for transmission offers several advantages, such as widespread coverage, high-quality signals, and the ability to reach remote areas where traditional wired transmission may be impractical.
In conclusion, TV channels use satellites to transmit live telecasts of music concerts or cricket matches with the help of computers. This technology enables viewers to watch these events in real-time from the comfort of their homes.

Definition:
A URL is a specific character string that provides a way to locate and access resources on the internet. It serves as a unique identifier for a web resource and helps browsers and servers communicate with each other.

1. Protocol: The protocol specifies the rules and procedures for communication between the client (browser) and the server. Examples of protocols include HTTP, HTTPS, FTP, etc.
2. Domain: The domain identifies the specific website or server where the resource is hosted. It is typically represented by a domain name, such as "example.com", which is converted to an IP address through the Domain Name System (DNS).
3. Path: The path refers to the specific location or directory on the server where the resource is located. It helps identify the exact file or page within a website.
4. Query Parameters: Query parameters are optional components that allow additional information to be passed to the server. They are often used for dynamic content generation or to pass data between the client and server.
5. Fragment Identifier: The fragment identifier is an optional component that points to a specific section or anchor within a webpage. It is preceded by a "#" symbol and is used to navigate to a specific part of a page.
Example:
