Plug-n-Play –
When a device or an expansion board is attached to a computer
system they should be running without rebooting your computer system.
Port –
A physical male or female sockets that can be hooked for plugging in
communication lines, modems and printers.
PPP (Point to Point Protocol) -
Protocol that is used by your dial-up modem
for your PC to connect to the Internet. PPP protocol runs between dial-up modem
and ISP. Once PPP connection is established, your PC gets Internet connectivity.
PPPoE (Point to Point Protocol over Ethernet) –
It is a method that
encapsulates PPP packets over Ethernet frames from the user to the ISP over the
Internet. PPPoE is preferable by ISPs because it provides authentication
(username and password) in addition to data transport. A PPPoE session can be
initiated by either a client application residing on a PC, or by client firmware
residing on a modem or router.
PPTP (Point to Point Tunneling Protocol) –
The protocol defines the tunneling
service in IP network to carry PPP protocol messages. One example of a tunneling
service is secure access from a remote small office network to a headquarters
corporate intranet via a Virtual Private Network (VPN) that traverses the Internet.
They can also be used for residential purposes.
RJ – 45 (Registered Jack – 45) -
A connector used for connecting Ethernet
devices that holds up to eight wires.
Reverse Network Address Translation – When
an Internet user tries to
access a service at your Router/Gateway, the request made by the Internet user
will be forwarded to an internal machine that serves the request. This is achieved
by translating the destination IP address of the packet to private Local IP address
of the PC where service is offered. This operation is exactly reverse of the NAT
operation.
Router –
Device that routes the packets across various sub networks that are
attached to. It helps in managing the large networks in to smaller ones. They
operate at IP layer of TCP/IP protocol suite.
Security Association –
These are the parameters to be set for having a VPN
tunnel.
Server –
A computer that services the users on a network, may be to access
files, web pages, printing.
Software –
It is a series of instructions that control the behavior of the computer
and its hardware.
Stateful Packet Inspection –
Firewall that monitors the state of the transaction
for the internal hosts. It looks at the internals of the packet and adjusts the
firewall policies automatically based on the state but specific to the port
requested/required. Hence this is more secured than the static packet filters
which are not intelligent of states of transactions.
Static IP Address –
Permanent IP address that is assigned to a host/router in
an IP or TCP/IP network.
Switch –
Device that connects host computers, large number of devices to share
a limited number of ports. 2. It helps users to make, break, and change the
connections physically on an electric circuit.
