The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like an array-a group of data elements stored together.
"An array is a collection of similar data elements stored in a structured sequence, often referenced or processed in loops." - CompTIA ITF+ Programming Concepts Correct answer: B

RAM allows multiple applications to run simultaneously. Insufficient RAM causes performance drops:
* "When several applications are open, the system relies heavily on RAM for temporary storage of active processes."
* Storage, motherboard, or NIC do not directly handle temporary application memory while multitasking.

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), one of the five critical steps when configuring a wireless router is to change the administrator username and password:
"The Wi-Fi Alliance lists five critical keys to setting up a secured wireless router:
* Change the router's SSID.
* Change the administrator username and password. Make sure that it's a strong password.
* Enable WPA3 or WPA2 Personal.
* Choose a strong security passphrase.
* Connect clients using the same security mode."
This ensures unauthorized users cannot log in to the router's settings.

To install and use a printer over a network, the printer must have an assigned IP address so that it can be located and communicated with by other devices on the same network.
"Network printers are assigned IP addresses so computers can locate and send print jobs to them over the network." - CompTIA ITF+ Networking Guide Correct answer: B

The CompTIA Tech+ Study Guide states:
"Nearly every program running on a computer is run as a process. This includes system operations, background tasks, and applications... The Task Manager utility helps you see everything that's running on a computer... If I have an app that's taking up too much memory, I can click it and then click End Task to shut it down. This is also known as killing the process." Thus, process management is the OS function that allows users to stop (terminate) running applications.
