▲Things which can be counted: count nouns
1.16 Many nouns have two forms, the singular form, which is used to refer to one person or thing, and the plural form, which is used to refer to more than one person or thing.
These nouns refer to people or things which can be counted. You can put numbers in front of them.
...book...books.
...day...days.
...three brothers.
...ten minutes.
These nouns make up the largest group of nouns in English. They are called count nouns or countable nouns.
▲noun-verb agreement
1.17 When you use the singular form of a count noun as the subject of a verb, you use a singular verb. When you use the plural form of a count noun as the subject, you use a plural verb.
A dog likes to eat far more meat than a human being.
Bigger dogs cost more.
▲use of determiners
1.18 Count nouns have a determiner in front of them when they are used in the singular.
He got into the car and started the motor.
They left the house to go for a walk after tea.
When you use the plural form of a count noun to refer to something in general, you do not use a determiner.

Most classrooms have computers.
However, if you are specifying a particular instance of something, you need to use a determiner.
