Which topology is better star or bus?

When there is a need for a wide network, then bus topology is preferred. This is so because it supports the easy addition of various devices in the network. While in star topology addition of devices is limited. The structure of the bus network is linear as various devices are connected through a straight cable.

What is Star Communication network?

A star network is an implementation of a spoke–hub distribution paradigm in computer networks . In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. ... Data on a star network passes through the hub before continuing to its destination.

1. Make the Decision to Commit. “It’s not the will to win, but the will to prepare to win that makes a difference.” This quote by Bear Bryant rings profoundly true. ...
2. Find A Deeper Reason. ...
3. Refine Your Goals. ...
4. Work Smarter, Not Harder. ...
5. Hold Yourself Accountable.

Which one of the following network topologies connects a central node to every device on the network acting as a multiport repeater?

In the star topology , all the computers connect with the help of a hub. This cable is called a central node, and all other nodes are connected using this central node. It is most popular on LAN networks as they are inexpensive and easy to install.

Why is it important to be dedicated?

When you are dedicated, you give everything you have—all of your efforts—to a cause or to a task . This is an important trait to exemplify in the workplace in particular. Setbacks occur, and if you are not dedicated, instead of stepping up, you will stay down and disappointed, which could lead you to quit.

Which connection provides a dedicated link between two devices?

Point-to-Point Connection :

A point-to-point connection provides a dedicated link between two devices.

What is multi point connection?

The multipoint connection is a connection established between more than two devices . The multipoint connection is also called multidrop line configuration. In multipoint connection, a single link is shared by multiple devices.

What are the 3 components of a network?
