Question

_____ is the physical link between a network and a workstation. a. The session layer b. An html address c. An adapter card d. A network topology

Answer 1

Answer:

An adapter card    

Explanation:

• The network interface card (NIC) also called network adapter is a network card that refers to the physical connection between the network and the workstation.
• This network can be from a local area network to inter-network (internet) .
• This means that a computer needs NIC to connect to a network.
• Network interface card is installed within the workstation and can be external (wireless adapters) or internal (on the motherboard)

• The NIC allows wired communication through connection like Ethernet or a wireless communication through WiFi.

• The performance of a network can be determined by NIC.

Session Layer is the layer of Open Systems Interconnection model OSI model which is used to set up, manage and terminate sessions between user application and processes running on the hosts. So this is not a correct option.

HTML address is basically an html tag which shows contact information for a person organization,  document or an article. So it is not a valid option too.

A network topology depicts arrangement of computer network i.e. how the host (computers) are connected to each other over a network. So its not a correct option.

Answer 2

Answer:

(d) Network topology

Explanation:

The physical or logical layout of all connecting devices including their connecting materials (such as cables) of a network is called the topology of the network. It is also the systematic and schematic arrangement of the devices (such as printers, scanners, computers, routers, bridges) that make up a network and their communication media. Examples of these communication media are twisted pair cable, optical fiber cable e.t.c

Types of topology (especially in a LAN - Local Network Area) are;

i. bus topology

ii. ring topology

iii. mesh topology

iv. star topology
