A zero-slot LAN is a local-area network (LAN) that uses existing serial and/or parallel communication ports on the computers in the network instead of requiring network interface cards (NICs) that would occupy an expansion slot.
Advantages
It leads to transmitting between computers over a serial or parallel port, thus freeing up an expansion slot normally used by LAN cards (NICs).
Disadvantages
Zero-slot LANs are typically slower than LANS that use NICs and are limited to two or three network nodes.
Advantages of bus LAN Advantages of bus LAN
LAN is wired WLAN is wireless
Lan are fast cheap and reliable.
expansion slot is what ive found on most web sites so this must be it hope i helped you out
No cables to trip over
A LAN card is an ethernet card that plugs into the ISA, PCI or PCIe slot in your PC and gives the system the ability to utilize a LAN as a communications link to other PCs or the internet.
up your bum
It slow down the network speed, when there is slow bandwidth of internet. We can not use it on internet due to its not secure.We can use it on intranet as we are getting 100 mbps and 1 gbps bandwidth in LAN environment.
Biggest disadvantage is security. Got to keep the bad guys out.
Loosely-coupled operating system for heterogeneous multicomputers (LAN and WAN) Offer local services to remote clients too primitive (lowest common demoninator - too much diversity)
speed is nothing wrong it the best except from u
Laptops can get internet or gain acccess to a local LAN.
