Define Network?

A network is defined as a collection of servers, computers, network devices, peripherals, mainframes or some other devices that are linked to one another to permit the data sharing. The Internet is considered as one of the main examples of the network that connects some people in all over the world.

Define network topologies and different types of networks?

The term network topology defines the relationship regarding the connected devices in the context of the geometric graph. Different devices are represented as vertices, and all their connections are represented as edges on the graph. It elaborates that how many connections each device has along with its order as well as sort of hierarchy. Typical network configurations involve mesh topology, star topology, hybrid topology, bus topology, ring topology and tree topology. Networks are categorized based on their different characteristics:

  • LAN (Local Area Network): It connects devices and connects in a limited geographic area like an office building, school and home.
  • WAN (Wide Area Network): It covers a large geographic area like spans, country and city.
  • MAN (Metropolitan Area Network): It is a large computer network that usually spans the large campus or a city.
  • PAN (Personal Area Network): It is a computer network which is utilized for the communication among computer as well as several information technological devices that is close to one person. Some of the major examples of devices that are utilized in Personal Area Network are personal computers, fax machines, printers and telephones.
  • HAN (Home Area Network): It is described as a residential LAN which is used for communication between different digital devices that are typically implemented in the houses, usually very small amount of computing devices as well as accessories like mobile computing devices and printers.
  • CAN (Campus Area Network): It is made up of an interconnection of local area networks within the limited geographical area.
  • SAN (Storage Area Network ): It is defined as a dedicated network that offers access to the consolidated, block level storage of data and utilized to create storage devices like tape libraries and disk arrays.

What do you mean by network design?

Network design refers to the planning regarding the deployment of infrastructure related to the network infrastructure. The network design is performed by the engineers, network designers, IT administrators and some other staff members related to it. It is done only before the deployment of the network infrastructure. Network design is defined as a category related to the systems design which deals with the mechanisms of data transport. As with other design disciplines regarding the system, the design of the network follows the stage of analysis, where needs are produced as well as precedes deployment, where the system is constructed. The main objective of the network design is to satisfy the requirements of data communication while decreasing the expense. The scope of requirement can vary widely from the single network project of network design to another based on the geographic particularities as well as the nature regarding the data requiring transport. The OSI model and TCP/IP are two different models that defines the connection regarding the network.

Different Network Design Issues

Different types of issues related to network design are as follows:

  • The protocol utilized should determine various channels required and the priorities that are to be utilized. This is based on the communication mode such as full-duplex, half-duplex and simplex.
  • The protocol that different layers use should be capable of correcting the sequence regarding the packets that received only if they are not in appropriate
  • The maximum data sizes in another major issue regarding the network design that can be sent as well as received in one attempt. It leads to the requirement for the segmentation at the sending end as well as re-assembling at the receiving end.
  • The identification of receiver and sender must be created possibly for all the layers. It can be achieved by some addressing.
  • The processes in the network design become inefficient in case of the very small size of the sending packets.
