NETWORKING
Introduction
Network connectivity in an important aspect in all businesses worldwide. Network connectivity
in the process of join networks to one another. It is done with the use of switches, gateways and
routers. Network connectivity is done in different topologies. The topologies include linear, hub,
star and tree designs. Each topology has its advantages and disadvantages (Shifrin & Keslassy,
2009).
Describe and explain the role and function of network connectivity in current computing
There are many role of network connectivity. As mentioned above network connectivity tends to
be using in most businesses today. Network has made the world become a global village.
Computer networks allows the computers to share data and the resources. The computer interact
with each other. There a number of functions if the network. The function of computer networks
include resource sharing, reliability of computers, communication medium, VoIP, e-commerce
and efficiency in economic ability for a business.
First, computer networks are best known for resource sharing. The network allows data,
equipment and programs available to everyone in a network. The data is shared in an effective
manner. Software and programs within a network ca be accessed by computers linked to a
network. The network also allows sharing of hardware equipment such as scanners, printers and
other devices ("Uses of Computer Networking | Synonym", 2018).
Secondly, the networks are useful in the reliability of computers and data. The network provides
high reliability by having different alternative of data sources. The alternative data sources are
helpful in cases of one hardware failure or data loss or corrupt data. The data reliability is very
important in business such as air traffic control, banking or hospital applications. Thirdly, the
computer networks are used in a communion medium. The computers have increased the speed
and volume of communication via emails and live chat programs. Today email is used in sending
texts, documents, videos and images. Computer networks have also helped in the VoIP. Voice
over Internet protocol has changed the telecommunication systems. Finally, the networks are
cost-effective systems. The networks have reduced the cost of establishment of computer
systems in various organizations. The role and functions of the computer networks are very vital
for any organization to ignore.

Describe and explain the principles of communication in networks.
There are a number of principles to consider in the communication via networks. The principles
include: Know the audience, the purpose of the communication, the communication media,
information presentations and the feedback ways. One must understand the audience in the
communication process. Understanding the person one is talking is very important. It could be an
employer to the employees. It could be employees to employees. The types of communication
between the two scenarios is different. Therefore one must ensure you understand your audience
(Peterson & Davie, 2012). Secondly, one must know the purpose of the communication. After
knowing the person involved in the communication, one should know the purpose of the
communication. For example, in mails the subject is meant to state the purpose of the
communication. When one reads the subject of the email, the person understands the purpose of
the communication. The third principle is the information presentation. One should know how to
use the communication media. For example, one should know how to use devices such as
phones, laptops, mail clients, social media platforms used in the communication process in the
networks. The information should be presented in an understandable way. If the information is a
solution to a certain problem. The message should be clear and helpful to the recipient. Finally,
the recipient should provide a response to the sender after receiving the message. Most device
today notify the sender that the recipient of the message have received the message. The
principles of communication ensure effective communication among people (Sixth IEEE
International Conference on Networking, Architecture, and Storage, 2011).
Describe the role and functionality of hardware and software entities that contribute to
network communications.
The networking hardware involve routers, switches, LAN cards, and cables. The routers are
important physical component in networking. The router facilitates the movement of data
between the devices used and the network. The router provides security in the network. The
router acts as the gateway between two networks. The router ensure that data goes to the right
destination. Data can’t go where it is not permitted. The router also enhance the security in a
network buy preventing virus and malware (Trivedi, 2013). The switch is used to receive
information from any source and dispatch the information to the intended destination. The switch
