Step by step
Solved in 4 steps
- To what extent have wireless networks improved in security over the last three generations? What exactly is the difference between the two?How does VoIP (Voice over Internet Protocol) utilize protocols like SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) for real-time audio communication?Data transfer protocols are used. the difficulties brought on by the employment of TCP and UPD in modern networks?
- Define the protocols commonly used in email communication, such as SMTP, IMAP, and POP3. How do they differ in their functionalities?protocols for transferring data. The difficulties presented by the employment of TCP and UPD in contemporary networksIn contrast to connection-based protocols, connectionless protocols offer their own set of advantages and disadvantages, both of which need to be studied.
- Why do certain protocols, such as HTTP, FTP, SMTP, and POP3, utilise TCP over UDP rather than another protocol? What are some of the key differences between routing and forwarding?How does NAT (Network Address Translation) work, and what is its significance in modern networking?How did wireless LAN protocols develop?
- Discuss the concept of NAT (Network Address Translation) and its role in network protocols.What is the total number of IPv4 addresses? Through the use of Network Address Translation (NAT), the lifespan of IPv4 addresses has been significantly extended (NAT). Is it essential for us to carry out a full IPv6 implementation?
