Spaying female cats is important for many reasons. First there is a problem with animal over population and when animals don't have homes they either become strays or go to the pound. When there are too many animals in the pound they may have to euthanize them because there are not anough people to adopt them. So it's best to prevent more kittens in the first place and adopt the ones that don't have homes first.

If pet cats are not spayed, then they will soon breed and you will end up with more cats than you can find homes for (or keep properly yourself). It is therefore sensible to ensure that your pet cat can not have kittens. Obviously if your cat is a pedigree cat and you intend to breed cats from her, you should not have her spayed, but you will need to keep her in the house and away form other cats that you do not want her to breed with.
Therefore having your cat neutered is widely considered part of responsible pet ownership.
Spayed female cats are called just that - spayed, or fixed, female cats.
Talk to your vet about this.

Spay or neuter depends on gender, not species. Females are spayed, males are neutered.
Normally, no. However, if parts of the ovarian tissue were not removed when she was spayed, yes she can.
not always
Yes, neutered male cats generally get along well with spayed female cats. Neutering reduces aggressive behavior and territorial instincts in male cats, making them more likely to peacefully coexist with female cats.
Keep them away from other intact cats of the opposite sex. It is much easier and less worrisome to have them spayed or neutered, however. Female cats will go into heat every 8 days if they are not spayed, and it is not a pleasant experience. Also spayed female cats have a largely decreased risk of ovarian and mammary tumors, and neutered male cats have a largely decreased risk of prostate cancer. If cats are neutered/spayed before they reach sexual maturity it will also prevent bad behaviors such as spraying.
No. Only female cats that have not been spayed can give birth.
Male cats are neutered and female cats are spayed.
