What are T1 and T3 lines
T1 and T3 lines are basically leased lines, which are used in the field of telecommunications. They are an example of reserved circuit communication that works through fiber optic cables and copper wiring.

Fiber Optic Cables
Fiber optic cables are expensive cables that are made up of thin strands of glass fibres, all of which is encased in insulated casing.

What is LTE?
LTE is a new form of wireless broadband. It is primarily for handheld devices and supports roaming on cell phones and PDAs and such.

What is Wimax
What is popularly known as WiMax, is actually a long range wireless networking standard. Through WiMax, users can receive high speed internet in even the most remote areas, where no other form of connectivity is available.

High Speed Satellite Internet
A high speed form of internet connection, satellite internet uses telecomm satellites to broadcast internet services, much the same as they do for tv.

Network Devices Tutorial - Routers - Hubs - Switches – Gateway
This tutorial is made to provide you enough basic knowledge about the some very important networking devices such as Network Interface Card (NIC) adapters, routers, hubs, switches, modems, communication cables, LAN/WAN routers, gateway and other important networking devices.

DHCP - Introduction to Dynamic Host Configuration Protocol
This particular chapter is about the DHCP server. DHCP stands for Dynamic Host Configuration Protocol. This tutorial is going to teach you all about DHCP router i.e. overview, troubleshooting tips, debugging, sub netting and Internet Protocol addressing.

Concept of Computer Dial up Connection
Dial up networking allows devices to connect to a LAN or WAN through telephone lines. It is often used for home users or networks, thus providers have special subscriptions for them.

What is an IP (Internet Protocol) Address - IPv4 - IPv6 Versions
IP is the most widespread standard for communications in the world, most of our networking equipment and software is reliant on IP or else on other protocols layered on top of IP.

Different IP Address Classes - Class A, B, C, D & E
There are 5 classes of the IPv4 address space; A,B,C,D and E, each of which contain a contiguous subset of the overall. Mostly the case is that the leftmost four bits of the address determine its class (for instance; All Class C addresses, for example, have the leftmost three bits set to '110', but each of the remaining 29 bits may be set to either '0' or '1' independently (as represented by an x in these bit positions):

A trace route is a special program that will monitor the network path of test data transmitted to a distant network. A trace route program is already there in the shell of Linux and unix, whereas on windows it is the equivalent of the trecert program which can be accessed through the DOS prompt.

What is ICMP?
ICMP is used in network management and administration. It is a networking protocol (in IP), as well as a control protocol, hence it is not used for transferring application data but network status.

What is HTTP?
HTTP is a standard communication protocol for web browsers and servers that allows them to interact. Hypertext transfer protocol is basically a networking protocol that is used by the software.

What is ARP?
ARP stands for address resolution protocol. It is used to transform an IP address to its corresponding physical network address. It is at the lower levels of networking protocol (layer 2of OSI model) and it is usually run in the device drivers of the network OS.
