Ethernet A LAN cable-and-access protocol that uses twisted-pair or
coaxial cables and CSMA/CD (Carrier Sense Multiple
Access with Collision Detection), a method for sharing
devices over a common medium. Ethernet runs at 10 Mbps;
Fast Ethernet runs at 100 Mbps. Ethernet is the most common
type of LAN.
Flash Flash refers to a type of memory that can be erased and
reprogrammed in units of memory known as blocks rather
than one byte at a time; thus, making updating to memory
easier.
Hot-Swap Ability to remove and add hardware to a computer system
without powering off the system.
IP Address A 32-bit address assigned to hosts using TCP/IP. It belongs to
one of five classes (A-E) and is expressed as 4 octets sepa-
rated by periods formatted as dotted decimals. Each address
has a network number, an optional sub network number and a
host number. The first two numbers are used for routing,
while the host number addresses an individual host within the
network or sub network. A subnet mask is used to extract net-
work and sub network information from the IP address.
IP packet filtering This is a set of facilities in network equipment that allows the
filtering of data packets based on source/destination
addresses, protocol, TCP port number and other parameters.
Packet filtering is one of the main functions of a firewall.
IPsec Short for IP Security Protocol , IPsec is an extended IP
protocol that provides encrypted security services. These
services enable authentication, as well as for access and
trustwothiness control. IPsec provides similar services as
SSL, but it works on a network layer. Through IPsec you can
create encrypted tunnels (VPN) or encrypt traffic between
two hosts.
Kerberos Kerberos was created by MIT as a solution to network secu-
rity problems. The Kerberos protocol uses strong cryptogra-
phy so that a client can prove its identity to a server (and vice
