Answer:
SCSI controller can hold several devices on a single chain
SCSI connectors are used in high-end servers
Explanation:
Small Computer System Interface (SCSI) is a physical cable to transfer data between a computer and high-end server, and for that, we cannot use this cable in laptops or tables, only we must see the size of the cable to understand and discard that two options, and an advantage of the cable is held several devices on a single chain.
Answer: There are different types of topologies are: 1) Bus topology, 2)Star topology, 3)Ring topology
Explanation: The physical layout in which the network connection are made is known as topology.
Types of topologies are explained as:
1) Bus topology-
- It is a type of network where every device is connected to a single cable, which runs one end to another.
- In this data is transmitted in one direction only and it is also known as linear bus topology.
- It is cost effective because they can be run in a single cable.
2) Star topology-
- In star topology every node in the network is connected to one central node.
- The central node or hub also acts as a repeater and it can manage the entire network from one location.
3) Ring topology-
- In this topology computers are connected to each other in circular format and every device in a network will have two neighbors.
- In this the risk of collision is very low and low cost to install.
