FC0-U71 Exam Dumps : CompTIA Tech+ Certification Exam

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

Gaming monitors are often described using refresh rates, which are measured in hertz (Hz), often specified in MHz for related processing frequencies. The CompTIA ITF+ FC0-U71 Official Study Guide states:

" Monitor refresh rate refers to how many times per second the screen updates, usually measured in Hz. "

" MHz (megahertz) is used for various frequencies, including GPU and monitor refresh processing. "

GPU and RAM refer to hardware components, TB measures storage, and MHz relates to the frequency, applicable for monitor performance metrics.

In object-oriented programming, methods are functions or procedures associated with an object that perform actions such as retrieving data:

“Methods are actions that an object can perform. They typically manipulate or retrieve data stored within the object.”

Variables store data, attributes define properties, and loops control repetition but do not directly handle data retrieval within objects.
