Although the values look numeric, the sequence “1, 10, 2...” suggests they are being treated as strings (text values), especially if they are not sorted numerically. In programming, strings are sequences of characters—even if those characters are digits.

“String data type is used to store alphanumeric characters, including numeric characters represented as text rather than numbers.” — CompTIA ITF+ Data Concepts

Correct answer: D

An access point is a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helps extend the range of a wireless network by creating additional coverage areas. This is directly outlined in CompTIA ITF+ documentation:

“A wireless access point (AP) is a device that allows wireless clients to connect to a wired network. It serves to extend or broaden the wireless coverage.”

In contrast:

A modem connects to the internet via an ISP.

A server provides network services, not range.

A host firewall protects a single device or network; it does not expand connectivity.

Thus, the most appropriate answer is D.

The correct order of storage units from smallest to largest is:

Kilobyte (KB)

Megabyte (MB)

Terabyte (TB)

Petabyte (PB)

“A kilobyte is approximately 1,000 bytes. It is smaller than a megabyte (1 million bytes), terabyte (1 trillion bytes), or petabyte (1 quadrillion bytes).” — CompTIA ITF+ Reference

Hence, C. Kilobyte is the smallest unit listed.

A GPU (Graphics Processing Unit) is a specialized processor designed to perform calculations related to rendering images and videos. It’s an example of a processing component.

“The GPU is a processor dedicated to graphical computations and image rendering, assisting or replacing the CPU in handling visual data.” — CompTIA ITF+ Hardware Essentials

Correct answer: C
