It is best suited to the token ring topology because the random-access method this topology uses detects data collisions.b. It distributes both data and processing tasks to the server node. The client-server model can use the bus or ring topology.c. It is most effective when used as a bus topology because its deterministic access method avoids collisions and prevents data loss during transmissions.d. It is more efficient than the bus or ring topologies because it transmits an entire file of records to the requesting node rather than only a single record.e. It is not used in conjunction with either the bus or ring topologies.arrow_forwardHow can passwords actually circumvent security? What actions can be taken to minimize this?arrow_forward

- Which of the following statements regarding authentication in conducting e-business is incorrect? Multiple Choice It is a process that establishes the origin of information or determines the identity of a user, process, or device We need to use asymmetric-key encryption to authenticate the sender of a document or data set Only one key is used for encryption and decryption purposes in the authentication process.

Packet switching combines the messages of multiple users into a packet for transmission. At the receiving end, the packet is disassembled into individual messages and distributed to the user. c. The decision to partition a database assumes that no identifiable primary user exists in the organization. d. Message switching is used to establish temporary connections between network devices for the duration of a communications session. e.
