depends how you want to connect them and what for.
A simple network connection just needs
4x Ethernet Cables (Cat 5e Recomended)
1x 4 Port Swich.
The switch should cost £20-30
The cable depends on length but should be fairly cheap.
If you want an internet connection perhaps you have a router already from the ISP this may have 4 slots on the back for ethernet cables so you could use that.
If you use a router there may be firewall settings to overcome to make the connection work.
All the components needed to connect 2 computers together are two Ethernet cards, a network switch and 2 Ethernet cables. Alternatively a single USB transfer cable can be used for simple file transfers.
Is a crossover cable needed to connect Host computers to the switch? Why or why not?
I would replace them all... you will use a "wiring schematic" to identify the faulty patch cables.
for connecting 4 computers you would need a "hub"(en.wikipedia.org/wiki/Network_hub), and a cat5 cable to connect each computer to the "hub". each computer would also need a "network card"(en.wikipedia.org/wiki/Network_card), alot of modern computers come with a network card integrated so you may not need to purchase it separately.
Do nothing unless there is a problem. They either work or don't work.
There are a few essential components needed to successfully set up a network for an office. The most important components will be an Ethernet router. The size of the router and the number of ports will depend on the amount of people that will be connected to the router. Ethernet cabling is also essential to connect the computers to the router. Connecting the router to a modem is also necessary in order to connect all the computers on the network to the internet.

It depends on model. Some modems come with a wireless router. If yours has wireless interface, you will able to connect your computers wirelessly. Usually what you have is a modem with one LAN port. If you want to connect your 3 computers to the same modem you need to get a wireless router. It will allow you to connect your computers using wireless or cable. Switch in such case might not work because of internet provider policy.
Crossover cables are used when you are connecting two devices of the same type together. e.g. connecting two routers or two switches or two computers. A straight through cable is used to connect devices of different types. e.g. a computer to a switch or router. Using the correct cable is less important these days though as most networking devices have the capability to auto-sense what cable is being used and what cable is needed. The devices can simply change their configurations to whatever is needed to make the connections work. This technology is called Auto-MDIX (Media Dependant Interface Crossover).
Most home theater systems require only the basic Audio and Visual cables, commonly known as AV cables. These are what connect the player (that is your DVD/BluRay/Etc) to the TV itself. HDMI cables may also be required to set up digital cable.
HDMI Splitters are devices used to connect HD TV's to certain other accessories, such as video game consoles and computers. They are needed to connect to outside entities.
