What is the significance of the United Sequence Number in the context of data transmission and network communication protocols?
The United Sequence Number is a crucial element in data transmission and network communication protocols as it helps ensure the accurate and orderly delivery of data packets between devices. It plays a key role in maintaining the integrity and reliability of the communication process by enabling the receiving device to correctly sequence and reassemble the data packets in the correct order. This helps prevent data loss, duplication, and errors, ultimately improving the efficiency and effectiveness of network communication.
What protocols do not guarantee delivery of their data but do operate with a very low overhead that conserves network bandwidth?
connectionless protocols - transport layer
What part of the network communication process is responsible for sending and receiving data to and from the network media?
protocols

What osi model layer do protocols manage data delivery priorities?
Network Layer
Which of the following are part of the context that protocols establish between devices before communication can take place?
The amount of data that the transmission media is able to carry. Transmission timing The method that will be used for transmission Information regarding the physical setup of the network All answers are correct.
How is data transmitted securely over a network?
Data is transmitted securely over a network through encryption, which scrambles the data into a code that can only be read by authorized parties with the correct decryption key. This ensures that even if the data is intercepted, it cannot be understood by unauthorized users. Other security measures, such as firewalls and secure protocols, also help protect data during transmission.
Why must network protocols be specified very precisely?
If data is to be transmitted correctly and any fallout or errors corrected, the protocols cannot be ambiguous at all.
Which two are protocols associated with layer 4 and osi model?
The two main protocols associated with Layer 4 of the OSI model, which is the Transport layer, are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP provides reliable, connection-oriented communication with error correction, while UDP offers a connectionless, faster method for data transmission without guaranteed delivery. These protocols are essential for managing data flow between devices in a network.
Transport layer protocols that do not establish a connection before transmission and make no effort to ensure that data is delivered error-free are called?
connectionless protocols
What is the average transmission time for data packets in the network?
The average transmission time for data packets in a network is the time it takes for a packet of data to travel from its source to its destination. This time can vary depending on factors such as network congestion, packet size, and the speed of the network connection.
