Computer Networks

BUS topology provides a common path shared by many users.

Total connection between path sender and receiver information is also called CIRCUIT.

It is not a type of transmission.

Satellite communication suffers from propagation delays due to large distance travelled by signals.

Satellite communication suffers from propagation delay due to large distance travelled by the signals. 

D channel is the lowest data rate because it is used for signaling with 16 kbps.

Synchronous and asynchronous are communication techniques.

FDDI ring uses two fiber rings, one transmits clockwise and other counter clockwise, if one breaks up other uses as backup.

This standard of IEEE is supplementary to the MAC layer in 802.11 to promote world wide use of IEEE 802.11 WLAN.

This functional entity of a GSM network contains the necessary hardware and software to enable and control the radio links with the mobile stations.

Systems that are designed to communicate with other systems based on standard protocols are known as open systems.

A Wide Area Network (WAN) is designed to cover large geographical distances, connecting institutions across regions, nations, or the globe. Other options like MAN cover cities, and VAN is a less standard term in this context.

The term 'modem' is a portmanteau derived from the words modulator and demodulator, which describe its function of converting digital signals to analog and vice versa.

A modem is the specific hardware device that modulates and demodulates signals to allow computers to communicate over analog telephone lines.

While modems are used for connecting to WANs or the internet, a Local Area Network (LAN) typically uses network interface cards, switches, and cables to connect computers and printers directly, without needing a modem.
