The head of a spider is called the cephalothorax ('head-chest'), as it also contains the chest structures such as the legs. Though, spider fangs are also unique among arthropods, these are also called chelicerae; and the pedipalps next to them don't have a counterpart in other groups either. In scorpions, the pedipalps are modified into pincers, but in Spiders they look like little legs and are used to manipulate food etc.
Assuming this question is how are insects different from other arthropods, insects fall into hexapods which includes insects, springtails and a few other groups of arthropods with six legs. Insects are different from other hexapods in that they possess a structure called a tentorium which is an internal support skeleton in the head made by extensions of the exoskeleton into the head.
Arachnids differ from other arthropods in that they have no antenna (nor wings, like many insects). They also use book lungs to breathe, rather than the gills or spiracle/trachea configuration. They have a body plan of only two sections (tagmata) and eight legs, although often with a modified forward pair different from most other arthropods.
Roundworms (Nematoda) are related to arthropods because they both molt.Note; Crustaceans are arthropods. :P
A spider may wait in tunnels for a millipede to pass and then eat it. They are eaten by other big insects like scorpions or lobsters. So their predators are basically any animal that eats or likes to eat arthropods.

Spiders are arachnids which are within the animal phylum of Arthropods. Some other arthropods are insects and other "bugs," crabs, lobsters, and even barnacles.
the anterior part of a crustacean (crabs etc) or other arthropods (such as the spider) which consists of a united head and thorax

Bees are classified as arthropods because of their characteristic segmented bodies, an exoskeleton made from chitin, and joint appendages.
In the UK, a daddy longlegs is a cranefly.In the US it can also mean two other spider-like arthropods.

The highest living arthropod is Euophrys omnisuperstes, literally 'living above everything else', a fluffy white jumping spider. It feeds on other arthropods that are blown up to its altitude, atop Mount Everest! Other arthropods above the snowline are fly species, mosquitos, bumblebees and other flyers. Bumblebees are frequent, others are there accidentally, mostly.
Snails aren't arthropods, they're molluscs. Other phylum.
It is hard to identify a spider without knowing how big it is, where it was found, its overall body shape and other characteristics. This could be a common house spider, a wolf spider, or a garden orb weaver.

Ladybugs are probably the most common eater of aphids.
