3.1.7 - Explain why protocols are necessary. Flashcards
Why are protocols necessary in networking?
Protocols are the set of rules computers follow when communicating across a network. Without them, no information can be transmitted, as computers wouldn’t know how to interpret the signals.
Why are protocols important for compatibility?
Protocols ensure that devices from different manufacturers can communicate effectively, regardless of their technical specifications, allowing seamless integration of various devices and software.
How do protocols ensure efficiency in network communication?
Protocols define the most efficient and effective way to transmit data, reducing delays, errors, and other inefficiencies that impact network performance.
How do protocols contribute to network reliability?
Protocols provide a consistent and reliable way to transmit data, ensuring that data is delivered correctly and in the right order, reducing the risk of data loss or corruption.
What role do protocols play in network security?
Protocols define security measures, such as encryption and authentication, to protect networks from attacks and unauthorised access, ensuring the privacy and security of communications.
How do protocols encourage innovation?
Protocols provide a standardised framework for new technologies and solutions, driving innovation by offering a common set of rules for developing new applications, services, and devices.
What is data integrity in the context of networking?
Data integrity refers to the overall completeness, accuracy, and consistency of data, which must be maintained when transmitting data through a network.
What is flow control in networking?
Flow control ensures that the rate of data transmission is proportionate to the receiver’s capability to process it, preventing the sender from overwhelming the receiver.
What is congestion control in networking?
Congestion control prevents the deterioration of network quality due to too much data being transmitted, applying techniques to avoid packet loss and queuing delays.
What is error checking in networking?
Error checking refers to techniques used to detect errors introduced during data transmission, often using parity bits to verify the integrity of transmitted data.
