Network in Computer Application in Business

  1. 1. Network
  2. 2. Network • A n/w is a set of devices (often referred to as node) connected by communication links. • A node can be a computer, printer, or any other devices capable of sending or receiving data generated by other node s on the n/w.
  3. 3. Distributed Processing • Most n/w’s are distributed processing , in which the task is divided among multiple computers. • Instead of one large single machine being responsible for all aspects of a process, separate computers ( usually a pc, or a workstation) handle a subnet.
  4. 4. Network Criteria • A n/w must be able to meet a certain number of criteria. • The most important of these are • Performance It can be measured in many ways, including transit time and response time. Transit time is the amount of time required for a message to travel from one device to another.
  5. 5. • Response time - it is the elapsed time between an enquiry and a response. • The performance of a n/w depends on the number of factors including no. of users , the type of transmission medium, the capabilities of the connected hardware and the efficiency of the software.
  6. 6. • Performance is evaluated by two networking metrics : throughput and delay. • We often need more throughput and less delay. • These two criteria are contradictory . • If we try to send more data , it may increase the throughput , but increases the delay.
  7. 7. Reliability • In addition to accuracy of delivery, n/w reliability is measured in frequency of failure. • The time it take to recover from a failure.
  8. 8. Security • N/w security issues include protecting data from unauthorized access , protecting data from damage and development , and implementing policies and procedures for recovery from losses .
  9. 9. Type of connections • A network is two or more devices connected through links. • A link is a communications pathway that transfers data from one device to another. • There are two possible types of connections: • Point-to- point , Multipoint
  10. 10. Point-to-point • A point-to-point connections provides a dedicated link between the two devices . • The entire capacity of the link is reserved for transmission between the two devices.
  11. 11. Multipoint connection • A multipoint connections is one in which more than two specific devices share a single link .
