Link
A link can be defined as a web address that is used to make connectivity between web pages.
Hyperlink
A hyperlink is simply a part of the Web page that is linked to a URL. A hyperlink can appear
as text, an image, or a navigational tool such as a button or an arrow. When you click on a
hyperlink, you will jump to the URL specified by the hyperlink. Hyperlinked text usually looks
different from normal text in a Web page. It is often underlined, but can be formatted in a
number of ways.
Bandwidth
The capability of a transmission medium to transmit the maximum amount of data from one
computer to another over a computer network in a given amount of time is called bandwidth.
A bandwidth is generally in bits per second (bps) or Bytes per second (Bps), Kilobytes per second
(Kbps) and Megabytes per second (Mbps). There can be various types of bandwidths which are
network bandwidth, data bandwidth or digital bandwidth.
i + DEVICES REQUIRED FOR A NETWORK
There are various types of devices such as Network Interface Card (NIC), Hub,
Switch, Router, Modem, Network Cable and Gateway. Let us discuss about
these in detail.
Network Interface Card (NIC)
The NIC joins a computer to a network and allows it to communicate with other
computers on the network.
Hub NIC
A hub is a networking device that allows us to connect multiple
computers to a single network. A hub works on the physical layer.
Hub or Switch It takes the input data from one of the ports and broadcasts the
information to all other ports connected to the network. It has no decision-making capability, so
it's a non-intelligent device. Only one transmission takes place on a network at a particular time.
Swtich
A switch has a decision-making capacity, so it is called an intelligent device that works in the
data link layer. It has knowledge of the machine and addresses of the ports in the network. A
switch is a secure device that establishes a link between the sender and the receiver, based on
the machine addresses to transmit information.
Router
A Router is used when multiple devices need to connect to the Internet
using the same IP. It works on the network layer. In other words, it
is used to connect and facilitate transfer of information between two
networks. Router
