Introductions
Everything nowadays is connected to the Internet and controlled by technology. As citizens of the twenty-first century, it is our job to keep up with the times and take control of modern achievements. As a networking engineer, we must investigate a variety of server kinds and determine the best topology protocol for the most efficient use of a networking system
Task 1: Discuss the benefits and constraints of different network
types and standards.
i. Definition of network.
A network is made up of two or more computers that are linked together to share resources (such printers and CDs), exchange files, and allow electronic communication. A network's computers can be connected by cables, phone lines, radio waves, satellites, or infrared laser beams.
Figure 1. Network Two very common types of networks include:
- Local Area Network (LAN)
- Wide Area Network (WAN) You may also see references to a Metropolitan Area Networks (MAN), a Wireless LAN (WLAN), or a Wireless WAN (WWAN).
a. LAN
Definition : LAN (Local Area Network) which is an internal computer network, this communication allows devices to connect to each other to work together and share data. This connection is made via a LAN cable or Wi-Fi (wireless) in a narrow space, so it can only be used in a limited range such as offices, homes, schools...
Disadvantage:
- The transmission line is short, can only work in a certain area.
- Server problem: The central server present on the LAN architecture manages all attached computers. If in case the server encounters any error, all the connected computers will also be affected.
- Malware Spreading:
b. MAN
Benefits: Constraints: c. WAN Benefits: Constraints: d. WLAN Benefits: Constraints: Protocol and Standards Network protocol definition (discuss protocols) Example protocols: TCP/IP HTTP DNS ICMP – (Discuss each and add more.)
Standard Organizations List some standard organizations and standards names P2. Network topology & communication and Bandwidth requirements Network topology definition. Discussion on the Impact of topology: …………………. Types of topology: What is Physical Topology? o The example of physical topology What is Logical topology? o Diagram of an IP addressing Table relating to logical topology. Examples of common topology discussion with diagrams
- Mesh
- Star
- Bus
- Ring
- Tree
- Hybrid Communication and Bandwidth Define commutations in terms of networking Rules of communication Bandwidth o Bandwidth requirements for the networks
DNS Server o Concept o Operating principles DHCP Server o Concept o Operating principles FTP Server o Concept o Operating principles P4 Discuss the inter-dependence of workstation hardware with relevant networking software. Explain what is meant by interdependencies Give examples of interdependency. Define workstation hardware Workstation hardware CPU, ROM, RAM, NIC Conclusion References Define networking software o OS o Web Server/Client o Email Server/Client Discuss and explain the inter-dependencies of workstation hardware with networking software. Derive an example form your discussion
M1. Compare common networking principles and how protocols enable the effectiveness of networked systems The common networking principles (circuit switching and packet switching) The advantages and disadvantages of circuit switching and packet switching Provide practical situations that are used for these switching principles M2. Server types and justify the selection of a server. Explore a range of common server types and give a brief outline of their uses Choose one of these servers, and justify your selection, based on a given scenario regarding cost and performance optimisation D1. Considering a given scenario, identify the topology protocol selected for the efficient utilization of a networking system. Consider a specific scenario of a network system The choice of this protocol for the purpose of making effective use of the network Conclusions (the whole report) Critical reflection
