The 4 port switch will only connect 4 hard wired (not wireless) computers, whereas the 8 port will connect 8.
Note that the amount of wirelessly connected devices supported will be the same, which is unlimited, or until the device blows up.
There is no difference; Ethernet is Ethernet, regardless of where it is deployed.
to split the Internet between different computers or to make it wireless if it is a wireless router
There is no difference.
Optimizing the performance of a wireless internet network requires the proper hardware. A router could be combined with an Ethernet switch to get the best possible speeds of data transfers and overall performance. Ethernet Switches offer more Ethernet ports than routers. For example, the number of Ethernet ports in Switches range between five and twelve. Ethernet switches or hubs also help to prioritize the data, which improves download and upload speeds when using a wireless internet network.
Ethernet is an alternative way of connecting to the internet when given wireless connection. It offers speeds of up to 10Mbps and four hubs can be cascaded between two stations. On the contrary, fast Ethernet has reduced number of hubs and offers speeds of up to 100Mbps.

Difference? Wireless allowed widespread, i.e. broadcast, communication.
There is no difference between a laptop or a desktop when setting up a router. You should use an Ethernet cable when setting up your router, and use the wireless only after it's setup.
No, wireless networks tend to be slower than wired networks but they offer more range and you don't need a whole lot of wires. Wireless routers normally have Ethernet ports so you can have a mix of wired and wireless if you desire. The speed difference between the two is barely noticeable, well that's my opinion.
Difference between wireless network and wireless sensor network?
Whether or not a network cable is connected to your computer.
Gigabit Ethernet almost always runs in full-duplex mode
