Which two of the following accurately describe the store-and-forward switching method?
Store-and-forward switching is a method used in networking where a switch receives the entire data packet before forwarding it to the appropriate destination. This approach allows the switch to check for errors and determine the best path for the packet, enhancing reliability and efficiency. However, it can introduce latency since the switch must wait to receive the complete packet before making forwarding decisions. Additionally, this method contrasts with cut-through switching, which begins forwarding the packet as soon as the destination address is read.
What are some of the characteristics of NetBEUI?
NetBEUI (NetBIOS Extended User Interface) is a networking protocol that is characterized by its simplicity and ease of use, making it suitable for small networks. It operates at the transport layer and is designed for local area networks (LANs), supporting small-scale network environments without the need for extensive configuration. NetBEUI is connectionless, meaning it does not provide reliable delivery of packets, and it lacks the routing capabilities found in more complex protocols. Additionally, it is limited to a maximum network size due to its broadcast-based communication method, which can lead to network congestion in larger setups.
What are the disadvantages of file organisztion method?
File organization methods can have several disadvantages, including inefficiency in data retrieval, especially when dealing with large datasets. They may also lead to data redundancy and inconsistency if not managed properly, as multiple copies of the same information can exist in different files. Additionally, updating or modifying data can be cumbersome, requiring manual changes across multiple files, which increases the likelihood of errors. Lastly, file organization methods often lack robust security measures, making sensitive data more vulnerable to unauthorized access.
