Daniel, F1 is a genetics term. It can refer to plants or animals. It is not excluisve to cattle.
F1 is a shorthand way of saying "first filial generation". Generation comprised of the first offspring from a given set of parents..

As an example, if you mate a hereford and an angus, these two animals would be designated the P1 generation-- Meaning the first parental generation in this case.

The off spring of the two parents would be the first filial generation in relation to the two parents, the F1 generation.
In this case, the offspring would also be crossbred. So they would be F1 crossbreds.

F1 has been used so much to refer to crossbreds that a lot of people think that is the definition.

or angus x barhman. as was mentioned it is the crossing of 2 purebred parents,
hereford x angus f-1 baldies, angus x gelbvieh balancer, etc.......

In genetics Ryder is correct. The F1 does not need to be a crossbreed. the F1 generation is the offspring of PURE breeding parents. So technically all purebred cattle at one time were F1's and then became the parent generation.
In the cattle biness F1 are the offspring of breeding two purebred parents of different breeds. It is not the pure definition but rather a working definition.

He is saying that the cattle business calls F1s the offspring of two different breeds but actually it can be the offspring of any two pure bred parents.
