Week11

  1. 1. How Circuit-Switched Digital Networks Work ● ISDN ● LAN ● TCP ● IP
  2. 2. ISDN(Integrated Services Digital Network) The ISDN (ISDN, Integrated Services Digital Network, synthesis digital network service) is the digital line network which packet transmission / circuit switching data communication digitized to a switchboard / trunk / member line entirely can use.
  3. 3. LAN ● The network which I connect a certain computer or a printer with a twisted pair cable and a coaxial cable, optical fiber in the same building, and exchange data.
  4. 4. TCP (Transmission Control Protocol) ● In the standard protocol ● used by the Internet, it hits OSI reference model's transport layer. IP in the network layer and the protocol more than the session layer are mediated.
  5. 5. IP(Internet Protocol) Internet Protocol address distinguishes a side near the network part and LSB (least significant bit) as a host part with a side near MSB (most significant bit). The network part specifies the network, and the host part specifies the equipment in the network. The subnet mask is used for the distinction between the network part and the host part.
