DHCP –
Dynamic Host Configuration Protocol. All hosts/gateways that are in the
network need to have an IP address to communicate. Without this protocol, you
have to manually specify the IP address in a host/gateway. This protocol allows
all IP address assignments to be centralized and automate the assignment of
Internet Protocol (IP) addresses in an organization’s network. The User of a
DHCP server can configure the lease time of an IP address to be used by a DHCP
client. It also supports static IP address assignment for fixed hosts/gateways if
they run application servers.
DMZ (De Militarized Zone) -
Allows one IP address (or computer) to be
exposed to the Internet. Some applications require multiple TCP/IP ports to be
open. It is recommended that you set your computer with a static IP address if
you want to use DMZ Hosting.
DNS –
Domain Name System maps the domain name against an IP address.
People remember meaningful domain names easily than the IP address that is in
the form of numbers.
Domain –
A sub network comprised of a group of clients and servers under the
control of one security database. Dividing LANs into domains improves
performance and security.
Download –
Receive the file from the network.
DSL –
Digital Subscriber Line, Your telephone line is used as a digital carrier that
can allow both data and your normal telephone. DSL can be always be powered
on. It need not be dialed every time you are trying to connect to Internet.
Daylight saving time (DST) -
time observed when clocks and other timepieces
are set ahead so that the sun will rise and set later in the day. The amount of
daylight on a given day of the year at given latitude is fixed, but over the year the
hours of sunrise and sunset vary from day to day. During the summer months,
the sun rises earlier and sets later and there are more hours of daylight. If clocks
and other timepieces are set ahead in the spring by some amount (usually one
hour), the sun will rise and set later in the day as measured by those clocks.
Dynamic IP Address -
An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
offer services like web, printer do not generally use DHCP. They are assigned with
static IP addresses.
Encryption –
A security method that applies a specific algorithm to data in order
to alter the data's appearance and prevent other devices from reading the
information.
Ethernet -
Supports 10 Mbps speed, this IEEE standard network protocol
specifies how data is placed on and retrieved from a common transmission
medium. This is the physical carrier for all TCP/IP protocol and its application
messages.
Fast Ethernet –
Same as Ethernet but supports 100 Mbps speed. Fast Ethernet
uses CSMA/CD network access method.
Firewall –
A firewall can be a software/hardware device that is located as
network gateway to protect your private network from the attacks that can
happen in the public Internet. It examines each packet to determine whether to
forward it towards its destination.
