True. Syntax refers to the way words are arranged in a sentence to make grammatical sense. When the subject (noun) and the predicate (verb) of a sentence do not agree in terms of number, person, or tense, it can create a syntax problem. This often results in a sentence that is grammatically incorrect and does not convey the intended meaning.

For example, the sentence "The dog barks loudly" is correct because the singular subject "dog" agrees with the singular verb "barks". However, if we change the subject to "dogs" and forget to change the verb to the plural form, we end up with a sentence that has a syntax problem: "The dogs bark loudly." In summary, the syntax is essential in constructing clear and grammatically correct sentences, and ensuring that the subject and verb agree is a crucial aspect of syntax.
Syntax refers to the arrangement of words and phrases to create well-formed sentences in a language. If a sentence has a noun and verb that do not agree, it indicates a problem with syntax. In English, proper sentence construction requires subject-verb agreement, which means that the verb must match the noun in terms of singular or plural form. Fixing the syntax issue will help make the sentence clear and grammatically correct.

This statement is generally true, with some caveats.

An allocation unit, also known as a cluster, is the smallest unit of disk space that can be allocated to store data and information on a hard disk drive or other storage device.

a file is saved to a storage device, it is divided into smaller units of allocation, each of which occupies a single allocation unit or cluster. The size of an allocation unit or cluster can vary depending on the file system used by the storage device and the formatting options chosen during initialization.

However, it's worth noting that while an allocation unit is the smallest unit of disk space that can be allocated to store data, it may not always be fully occupied by the data stored within it. For example, if a file is smaller than the size of an allocation unit, the remaining space within the allocation unit will be left empty. Additionally, some file systems may use larger allocation units, which can result in wasted disk space when storing small files.

Overall, while an allocation unit is typically the smallest unit of disk space that can be allocated to store data and information, the actual utilization of space within each allocation unit may vary depending on the size of the stored file and the formatting options used.
