 Is "a" needed here?
Hi !
What's wrong with these sentences?
1- Keyboard looks like a typewriter.
2- Keyboard is an input device used for entering the data into the computer.
Someone told me that there should be "a" before each sentence (e.g.A keyboard) and there shouldn't be "the" before data. Are they right? I don't understand when I should use "a" with a countable noun and when not.
Regards!
