Who sets these hopeless homework questions ??
Essentially all data comms are 'serial', Networking is a generic term that may be used in multiple context (egg. 'Social networking') and LAN means 'Local Area Network' (and could mean the cables, wireless etc supporting the Serial Data Comms or a sloppy usage meaning 'connecting to the Internet' (strictly, this is WAN = Wide Area Network) :-).
Serial is a specialist method of connecting two machines -
a) in the PC-PC Serial Port case it is only used for diagnostic / monitoring functions (eg. Command Console) where one PC's display/keyboard is not functioning ..
b) PC to UPS (Uninterruptable Power Supply) - used to allow a UPS to inform a PC the mains power has failed and request a shut-down when the UPS batteries are (nearly) exhausted
c) PC to 'equipment' (eg. Office Photocopier) - was used for diagnostics and firmware updates (most modern kit uses Ethernet port instead)
d) Generic case - Games Consoles control 'paddles' are often Serial .. modern Hard Disks (SATA) use Serial comms .. and so on ...
Assume Networking means 'computers sharing files eg. via a LAN or WAN, and communicating together eg. via the web'
Assume LAN means 'physical hardware linking (local) computers together by wires or wireless'

Serial is much slower and not a good reliable way to network. You need to go with 10/100 lan cards and cat 5 cable.

Parallel is extremely unusual at the instant. Printers related to private computers used to regularly parallel, serial became unusual by way of fact it became slower. yet now each and every thing seems to be serial; USB the main hassle-loose.
