Computer Network
Computer network means an interconnected collection of computers (or multiple processors software & hardware) such that they can:Exchange information, Sharing resources each other
Examples:
Internet
Cellular Network
Key Issues For Computer Network
The following are the major key issues Computer Network:
Nature of Nodes: Whether participating nodes are homogeneous or heterogeneous in nature?
Topology: Which of the computer topology has to be followed? Computer topology accounts for the physical arrangement of participating computers in the network.
Interconnection Type: Whether interconnection type is point-to-point, multi-point, or broadcast type.
Reliability:
How reliable our network is? Reliability aspect includes error rate, redundancy and recovery procedures.
Channel Capacity Allocation:Whether allocation of channel capacity is time-division or frequency division?
Channel Capacity Allocation:Whether allocation of channel capacity is time-division or frequency division?
Routing Techniques: Whether message between nodes are to be routed through: Deterministic, Stochastic, and Distributed routing techniques?
Models: Which of the models i.e. analytical models, Queuing models, Simulation models, Measurement and Validation models are applicable?
Channel Capacity: What are the channel capacities of the communication lines connecting nodes?
Access: Whether computer access in the network is direct-access or through a sub-network?
Protocols: What levels, standards and formats are to be followed while establishing communication between participating nodes?
Performance: How is higher performance of computer network achieved? Response time, time to connect, resource utilization, etc. contribute towards performance of computer network.
Control: Whether centralized control, distributed control or hierarchical control of participating nodes of computer network is suitable?
