COMPUTER NETWORK PROTOCOL

COMPUTER NETWORK PROTOCOL

1. How network protocols work?

   • break larger processes into discrete, narrowly defined functions and tasks
     • Systems Interconnection model,(OSI)
       • Layers
   • some types protocols
     • Transmission Control Protocol (TCP)
     • Transfer Protocol (FTP)
     • Hypertext Transfer Protocol(HTTP)
     • Internet Protocol (IP)
     • User Datagram Protocol (UDP)
   • Every packet contains
     • binary data
     • header or footer
       • Store information (sender and destination)
   • Major types of network protocols
     • Communucation
     • Management
     • security

2. What it is?

   • sets of established rules that dictate how to format ,transmit and receive data
   • provide a common language for network devices

3. Implementing Network Protocols

   • In order for network protocols to work, they must be coded within software
     • part of SO
     • app
     • implemented within the hardware
   • Vulnerabilities of network protocols
     • Are not designerd for security
       • eavesdropping
       • cache poisoning

4. Uses of network protocol

   • Internet

5. Advanges of network protocol

   • Anyone can connect to a computer network –
   • Central Storage of Data
   • Faster Problem solving
   • Reliability
   • highly flexible
   • Security through Authorization
   • It boosts storage capacity

6. Disadvantages of Network Protocol

   • It lacks robustness
   • Virus and Malware
   • It lacks independence
   • Cost of Network
