what is semantics?

Answer 1

http://en.wikipedia.org/wiki/Semantics

Answer 2

Do you mean in the computer sense? if yes then continue reading. There are 3 main types of semantics,

Operational semantics
describes the meaning of a program in terms of how it is executed, for example by specifying the individual steps in its computation, or by describing an abstract machine that evaluates the program.

Denotational semantics
describes the meaning of a program as a mathematical object, typically as a function that takes a state of a computer (its initial state before the program is run) and returns an updated state (the state of the computer that results from executing the program.)

Axiomatic semantics
describes the logical properties of programs; typically, an axiomatic semantics says that if some property holds before a program is run, then some other property will hold after the program has run. For example, the semantics of a program to compute the minimum of two numbers x and y might state that if x is less than y then (on completion of the program) the value stored in a variable min is x.

I suggest you read http://www.csc.liv.ac.uk/~grant/Teaching/COMP317/ to get a full understanding of the subject. If you have any specific questions after reading, il be happy to answer your questions.

Good Luck!

Answer 3

refers to the aspects of meaning that are expressed in a language, code, or other form of representation of information.
Semantics is contrasted with two other aspects of meaningful expression, namely, syntax, the construction of complex signs from simpler signs, and pragmatics, the practical use of signs by agents or communities of interpretation in particular circumstances and contexts.
semantics may also denote the theoretical study of meaning in systems of signs.

Answer 4

in programming syntax is the rule
and semantics are the meanings

Answer 5
