Local networking speeds depend on the equipment you are using internally. The standard speed on wired LAN connectivity (a network cable plugged into your computer) is 1Gbps. If you utilise servers and advanced storage equipment, you may find your office LAN connectivity is 10Gbps. Regarding internet (WAN) connectivity, that depends on what is available in your area. Most small businesses are on FTTC (fibre to the cabinet) which is capped at 80Mbps download and 20Mbps upload. Many businesses these days have the option for FTTP (fibre to the premises) or Leased Lines which carry speeds in excess of 1Gbps and should be used where connectivity is critical to running the business.
