Comprehensive Report: Computer Networking and Management Analysis

This report provides an overview of computer networking and management, covering key concepts such as network models, including protocol layering, the TCP/IP protocol suite, and the OSI model. It also delves into switching methods, comparing circuit-switched and packet-switched networks. The report further explores the significant changes 4G wireless networks bring to connectivity, differentiates between leadership and management, and explains the functions of management. The content includes summaries of network models, switching, and the advantages of 4G networks, alongside a discussion of leadership versus management, and the core functions of management, drawing from various sources and providing a comprehensive analysis of these interconnected topics.

Introduction
Report is about Management information and computer networking. Report will explain
Network models and Switching. Chapter of Network models will explain Protocol layering,
TCP/IP Protocol suit and OSI model. Chapter of Switching will explain Circuit-switched
network, Packet-Switching and Structure of a switch. Besides this, report will also answer why
will 4G wireless networks bring about significant changes in connectivity? With this difference
between Leadership and Management is also explained in the report and management is also
explained separately.
Network models- Summary
Sender, receiver and other intermediaries have to follow all the rules and regulation describe by
the Protocol for effective communication. At the time of simple communication, we just need
simple protocol but protocol layering is used at the time of complex communication. Principals
of protocol layering, first principal explains that to perform opposite tasks we have to make
different levels in all the direction for bilateral communication and second principal that should
be followed is objects at each layer of both the edges should be same in protocol layering. After
studying both the principals it can be said that there is a reasonable connection in each of the
layers. It shows that there is layer-to-layer communication and the sender and receiver can also
imagine that there is reasonable connection at all the levels and will help them to send their
messages to each other (Forouzan, 2007).
TCP/IP protocol suite is one of the example to protocol layering and different layers that are
involved in this are Hardware Devices, Network Interface, Internet, Transport and Application.
Communication among the two objects in that these suits are involve. Communication between
two objects takes place with the help of switch and router. Router is the one that connects one
switch with another switch. Logical connections between the two host shows that the message
send by the Source host to the destination host goes through the link 1 i.e. LAN to link 2 i.e.
LAN and then reaches to its destination host. Both the LAN’s are connected with the Router.
Identical objects are also involved in the TCP/IP protocol suits. Encapsulation and decapsulation
is the concept involved in the Protocol layering. Procedure of opening the data which is
encapsulated is known as Decapsulation (Forouzan. 2013).

Addressing is another concept of Protocol layering. It explains that parties that are involved in
the communication require two addresses known as address of source and address of destination.
Physical layer do not need address as the data exchange at this layer is a bit. Multiplexing and
Demultiplexing are the protocols used at some layers by TCP/IP protocol suits at source and
destination. Multiplexing means a packet can be encapsulated by a protocol from other advanced
layer protocols. Demultiplexing means a protocol can deliver packet and decapsulate to other
layers of protocols. OSI model involve seven layers such as Physical, Data link, Network,
Transport, Session, Presentation and Application. Presentation and Session are the two layers
that were not included in TCP/IP protocol suite and three layers combination in OSI model is
application layer in suite.
Switching- Summary
Switching is used to connect multiple devices to make communication possible. Message
switching, Packet switching and Circuit switching are the methods of switching. Circuit
switching and Packet switching are used commonly. Datagram and Virtual-circuit approach are
the two subdivisions of Packet switching. Switching can be placed at the TCP/IP protocol suit’s
layer. Physical links connected by sets of switches is known as Circuit-switched network.
Dedicated path connects two stations. FDM is used to divide each link. Trivial circuit-switched
and circuit-switched network are explained in the chapter with example. For communication
three phases are essential in circuit-switched network: Connection teardown, Data transfer and
Connection setup. Message is divided into fixed packets if it is going through packet-switched
network. All the packets are treated individually. Packets are known as datagrams. Virtual-circuit
network involve characteristics of Datagram and circuit-switched network. Switches are used in
both packet-switched and circuit-switched network. Time-division and space-division switch are
the technologies used in circuit switching. Circuit-switched and packet-switched network use
switch of different structure. Components of packet switch are; Switching fabric, input ports,
routing processor and output ports (Forouzan, 2006).
Why will 4G wireless networks bring about significant changes in connectivity?
 Data packets of internet protocol are conveyed by data network and permits huge data to
move with the network.
 Possibility of 4G network is around 31 miles lower the optimal limitations.
 Hand off is removed by 4G network without any disturbance.

 4G network is proficient to transfer more description, digital TV for best tools.
 It contain portable virtual games, improved GDS and telemedicine.
 Time can be saved with wireless 4G network.
 At some place and time it can beneficial.
 Evolution and testing is needed and high data rates are offered by 4G network.
 Mobile communication is exclusive in this with less cost.
 It is very cooperative.
 Stable and complete networks are maintained by them (Domyhw. 2016).
Difference between Leadership and Management
Leadership means ability of a person to lead a group of people or an organization and
management is the process of getting things done through others for achieving organizational
objectives.
 Vision is formed by Leaders and Goals are formed by Managers (Key differences. 2015).
 Managers copy and behave according to their learning but leaders have their own unique
and leadership style.
 Manager’s focus on short-term objectives and leaders focus on long term objectives.
 Processes and systems are formed by managers and relations are maintained by leaders.
 Risk is taken by leaders and controlled by managers (Arruda, 2016).
Management
Management is the process of getting things done through others with the aim of achieving
organizational goals and objectives. Management involve different resources such as: financial
resources, natural resources, human resources and technological resources (Management
innovations. 2008). Management also involve different styles such as: Servant management,
Team management and Traditional management. Function of management are Planning,
Organizing, Staffing, directing, Controlling and Motivation (Lumen. (2017).
Conclusion
In the conclusion it can be said that protocols should be followed by sender and receiver of
messages for effective communication. Different protocols are explained above in the summary
of Network models and Switching. Benefits of 4G networks are also explained above. With this
difference between leadership and management is also discussed above.
