4. The correct answer is [b] Token Ring. Token Ring is a network protocol that specifies that computers and devices on the network share or pass a special signal called a token. This token is used to control access to the network and prevent collisions.<br /><br />5. The correct answer is [b] Firewall. A firewall is a software program or a hardware device that filters all data packets coming through the internet, a network, etc. It acts as a barrier between a trusted network and an untrusted network, and it can be used to block unauthorized access, prevent certain types of traffic, and protect against malicious attacks.<br /><br />6. The correct answer is [b] Transmission Control Protocol/Internet Protocol. TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a suite of communication protocols used to interconnect network devices on the internet. TCP provides reliable, end-to-end data transport, while IP provides routing and addressing for data packets.<br /><br />7. The correct answer is [c] biometrics. Biometric authentication is a type of authentication that reads a unique personal characteristic, such as a fingerprint, face, or voice, to identify the user. This method is considered more secure than traditional methods, such as passwords or PINs, because it is difficult for others to replicate or steal a person's unique biometric characteristics.<br /><br />8. The correct answer is [a] password. Passwords are used to compare data with a set of rules or values to determine if the data meets the criteria. When a user enters a password, it is compared with the stored password for the account. If the passwords match, the user is granted access to the account. Passwords are commonly used as a form of authentication to protect sensitive information and prevent unauthorized access.
