Introduction
Computer networking is the process by which computers exchange data and resources. There are
various components and protocols that supports networking. This report explains this
components and their functions .Different network protocols are also explained and how they are
used by network devices to communicate.
Role and functioning of network connectivity
Network connectivity describes the process of connecting various parts of a network to one
another to enhance communication with each other. Network connectivity describes how
switches, routers and gateways are used in network connection to support communication in any
give network (Du $ Hsu, 2013). Network connectivity has various roles and functions in any
network. Its roles and functions include the following.
 Network connectivity makes business organizations reduce their daily expenses by
sharing of resources such as printers and scanners among many different computers.
Printers can be shared by carrying information from one computer to another by use of
floppy disks but switches and routers give a way of sharing information in a very easy
and simple way that does not frustrate the network users. Also switches have the capacity
to hold more users who can share resources in network
 Network connectivity has made work easier by giving computers the power of sharing.
Mainframe computers can currently be used to process large amount of data while the
min-frame computers can be used in processing data that require little resources like
word processing (Hou et al,2008). Data that is then processed by different computers can
then be shared between the computers.
 Many software also offer license agreement software which is more cost effective than
purchasing individual software of the same version for each machine. Network
connectivity also made backup of data to be very simple .Many files can be stored in
machines that are within the same network than being stored in individual machines. This
makes the risk of losing data to be very minimal for computers within the network.
 Network connectivity is promoting cloud computing. This is where data can be stored,
access and processed over the internet. Currently most organization are storing important
information on cloud for security purposes.
