devices that serve multiple users, such as servers and printers, are usually
assigned static IP address.
Ethernet
– IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Firewall
– A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a network from users from other
networks. (The term also implies the security policy that is used with the
programs.) An enterprise with an intranet that allows its workers access to the
wider Internet installs a firewall to prevent outsiders from accessing its own
private data resources and for controlling what outside resources to which its
own users have access.
Basically, a firewall, working closely with a Gateway program, examines each
network packet to determine whether to forward it toward its destination.
Firmware
– Programming that is inserted into programmable read-only
memory (programmable read-only memory), thus becoming a permanent part
of a computing device.
FTP
(

network (Internet, UNIX, etc.). For example, after developing the HTML pages
for a website on a local machine, they are typically uploaded to the Web server
using FTP.
FTP includes functions to log onto the network, list directories, and copy files.
It can also convert between the ASCII and EBCDIC character codes. FTP
operations can be performed by typing commands at a command prompt or
via an FTP utility running under a graphical interface such as Windows, FTP
transfers can also be initiated from within a Web browser by entering the URL
preceded with ftp://..
Unlike e-mail programs in which graphics and program files have to be
“attached,” FTP is designed to handle binary files directly and does not add
the overhead of encoding and decoding the data.
