Computer Networks

ISP stands for 'Internet Service Provider,' which is a company that provides individuals and organizations access to the Internet and related services.

IP stands for 'Internet Protocol,' which is a fundamental protocol used for routing and addressing packets of data so that they can travel across networks and arrive at the correct destination.

In full-duplex mode, the communication channel allows data to be sent and received simultaneously in both directions, unlike simplex and half-duplex modes.

In Adhoc mode, computers communicate directly with each other without the need for a central access point, allowing them to send frames directly to one another.

A modem (modulator-demodulator) is the device that converts digital data into analog signals for transmission over analog lines and converts received analog signals back into digital data, enabling digital communication over analog infrastructure.

Ethernet LAN speeds commonly include 10 Mbps (10BASE-T) and 100 Mbps (Fast Ethernet). Both speeds are standard and widely used, so the correct answer is 'Both A and B'.

A LAN (Local Area Network) is a data communication system confined to a limited geographic area such as a building, plant, campus, or nearby buildings, making it the correct choice.

MAN stands for Metropolitan Area Network, which is a type of network that covers a larger geographic area than a Local Area Network (LAN) but smaller than a Wide Area Network (WAN).

Multiple users can access a mainframe through terminals, which are input/output devices connected to the mainframe. Terminals allow users to interact with the mainframe remotely. Options like 'Cluster Server frame' are not standard terms for mainframe access.

A mesh topology requires each computer to be connected to every other computer, resulting in the most extensive cabling compared to star, bus, or ring topologies.
