Question

Another consideration for the IT manager is whether to wire the computers with point to point and multi point circuits. create a 2x2 matrix with point to point and multi point circuits on the vertical axis, and the pros and cons on the horizontal axis. fill in the matrix with the pros and cons of each technology. consider costs, speed, responsiveness, flexibility, and future growth.

Answer 1

        In this question, an IT manager want to figure out whether to wire the computers with point to point circuits or multi point circuits.

   The point to point and multi point circuits are types of line configuration that describe a method to connect two or more devices in a link.

Point to Point Circuits :    

In point to point circuits,

> The link is only between two devices i.e a sender and a receiver.

> The Capacity of the entire channel is reserved only for the transmission of the packet between the sender and receiver.

> There is a single dedicated link only between two devices.

Multi Point Circuits :

In Multi Point circuits,

> The link is between a sender and many receiver

> A single link is shared by more than two devices.

> The Channel capacity is shared temporarily by the devices in connection.

Lets us list the pros and cons of point to point and multi point circuits :

	Point to Point Circuit	Multi Point Circuit
Pros	1.It is very easy to install and maintain 2.Highest Bandwidth as there is an dedicated link between two nodes 3.Node can be replaced easily.	1.It is easier to add more users in a multi point connection. 2. It leads to low cost as link are shred between different devices. 3.The failure of a single node does not cause the entire network to fail as there are alternate paths for data transmission.
Cons	1.It can only handle two nodes in a network 2.The entire network depend on the single link in case the link broken the entire network will be dead. 3.There are only two nodes if any of the node stops working ,data cannot be transfer across the network. 4. It is costlier.	1. Speed is slow as the link is shared by different devices. 2. Owing to its complexity ,the administration of the circuit is difficult.
