| | Define VOIP Communication Technology
|
| Here are the basic interview questions

| model.
| |
| | Wi Max is a wireless broadband technology
|
| What is DHCP?
| |
| | and it is a advance shape of the Wi Fi
|
| DHCP stands for Dynamic Host
| |
| | (which was a base band technology). Wi

| | Max supports data, video and audio
|
| purpose of the DHCP is to assign the IP

|
| other network settings to the client

| | Network Gateway can be software or a

| computers. DHCP reduces the

| |
| | point in a network i.e. it connects two
|
| the IP addresses to the large number of
| |
| | networks. A computer with two LAN cards

| the computers in a network.
| |
| | can act as a gateway.
|
| What is DNS and how it works?
| |
| | What is a Router?
|
| DNS stands for Domain name system and it
| |
| | A router routes the traffic to its
|
| translates (converts) the host name into
| |
| | destination based on the source and
|
| the IP address and IP address into to the
| |
| | destination IP addresses, which are
|
| host name. Every domain and the computer
| |
| | placed in the routing software known as
|
| on the internet is assigned a unique IP

| | Fiber optics provides the fastest

| this format 10.1.1.100, 220.12.1.22.3,

| | Data can travel at the speed of light
|
| 1.1.1.1 etc. IP addresses can't be
| |
| | through the fiber optic cables. ISPs and

| remembered but the host names (e.g.
| |
| | corporate offices are usually connected
|
| xyz.com, abc.com) are easy to remember

| instead of their IP addresses.
