Answer:
A. Loopback tool
Explanation:
Loopback tool or adapter is a small device used to test networks ports and help identify simple network connection issues, this is a great tool when mapping out a physical layout of a network and quickly identify active ports on a switch.
This tool works by taking the transmitted signal and redirecting it or looping it back into the receiving end of the same connection.
A system's compliance with its stated requirements is assessed through system testing, which is testing done on an entire integrated system.
<h3>What is system testing?</h3>
A system's compliance with its stated requirements is assessed through system testing, which is testing done on an entire integrated system.
All integrated components that have passed integration testing are the input for system testing. Integrity testing is used to look for discrepancies between units that are integrated together (called assemblages). The goal of system testing is to find flaws in both the "inter-assemblages" and the system as a whole. The behavior that is generated or noticed when a component or system is tested is the actual result. [1]
In the context of either functional requirement specifications (FRS) or system requirement specifications (SRS), or both, system testing is conducted on the complete system. System testing examines both the behavior and the design.
Hence, A system's compliance with its stated requirements is assessed through system testing, which is testing done on an entire integrated system.

Answer:
Logical Expressions
Explanation:
The expressions that have logical statements which could be "true or false" are known as logical expressions. These types of expressions are also known as Boolean Expressions.
These expression are used in computer programming. The purpose of these expressions in programming is to make a decision that could be based on different conditions. These conditions could be true or false. This is the main reason that. logical expression makes best sense for values received in true or false.
