DNS (Domain Name Service)
DNS is a service available on TCP/IP-based networks which assigns easy-to-remember
names (e.g. computer.domain.com) to numeric addresses (e.g. 198.168.148.144).
Programs such as Telnet, SMTP or FTP use DNS to locate an IP address on the basis of
the name provided.
•
Gateway
A gateway is used to connect networks while providing protocol, data structure format,
language and/or architecture translation.
•
Router
A router connects local area networks or wide area networks, and controls the flow of
packets between these networks. If more than one possible connection exists between
two networks, the router will select the most efficient or cost-effective route.
•
Segment
In an Ethernet environment, a segment means a section of a cable which serves as a
bus. Signals broadcast within a segment reach every workstation connected to that
segment.
•
Host
A host is a device (e.g. a computer or a printer) to which a network address is assigned.
•
WINS
WINS (Windows Internet Name Service) supports distinguishing between computer
names by translating them to assigned IP addresses, and performs a reverse process,
i.e. resolves IP addresses to Windows names.
•
Hub
A hub is a device used to transmit signals or data from one computer to all other
computers connected to that hub.
•
Switching Hub
A switching hub differs from a standard hub with increased performance and the ability to
offload the network. Higher performance and reduced network load are achieved by
using the port switching functionality, and specifically by transmitting data only to the
target computers (a standard hub transmits data to all computers, thus significantly
congesting the network).
