Harware vs Software

• Hardware is Faster but can't be changed easily
• Software can be Changed Easily but is slow
• Firmware is Fast and Flexible

Network Interface Card

• Plugs into either a PCI or ISA slot on a PC
• Cable or Fiber plugs into the NIC and attaches it
  to the network
• NIC is unique for the Type of network e.g. Token
  Ring, Ethernet, ATM etc.
• However a Network Type may use different types of
  NICs

Thicknet

• Older Technology Uses Coax and AUI cable
• You still see AUI interfaces on Routers

Thinnet

• A simple arrangement that doesn't require a Hub
• Uses Coax and BNC connectors
