Detailed explanation-1: -If a packet is lost, TCP can retransmit it. The second transmission picks up lost packets and reconstructs the data stream. However, this does not mean there is no slowdown involved. The network may feel slower, as it still takes time to retransmit data.
Detailed explanation-2: -At peak times, when network traffic hits its maximum limit, packets are discarded and must wait to be delivered. Fortunately, most software is designed to either automatically retrieve and resend those discarded packets or slow down transfer speed.
Detailed explanation-3: -Disadvantages of packet switching: High-volume networks can lose data packets during high-traffic times; those data packets cannot be recovered or resent during transmission. There is a lack of security protocols for data packets during transmission.
Detailed explanation-4: -Transport Control Protocol or User Datagram Protocol The main difference between TCP/IP and UDP/IP is that, although both are IP, TCP is a method for ensuring that every packet reaches its destination. When one does not, the destination computer makes a request to the transmitting computer to resend the missing packet.
