No. The modem is used to connect to an outside network (to the Internet); in other cases, an ADSL router is used, or some other device, depending on the type of Internet connection.To share devices within your network, the key device is either a hub or a switch.No. The modem is used to connect to an outside network (to the Internet); in other cases, an ADSL router is used, or some other device, depending on the type of Internet connection.To share devices within your network, the key device is either a hub or a switch.No. The modem is used to connect to an outside network (to the Internet); in other cases, an ADSL router is used, or some other device, depending on the type of Internet connection.To share devices within your network, the key device is either a hub or a switch.No. The modem is used to connect to an outside network (to the Internet); in other cases, an ADSL router is used, or some other device, depending on the type of Internet connection.To share devices within your network, the key device is either a hub or a switch.
These are called protocols - a standard set of rules for common communications across networks.
Two types of computer networks are LAN (Local Area Network), which connects devices within a small geographic area like an office or building, and WAN (Wide Area Network), which connects devices over a larger geographic area, such as across cities or countries.
The NAT (or Network Address Translation) is basically something which allows your router to share an IP across different devices.
