can you connect wireless modem to a switch which will to two routers

Usually you would find a considerable amount of information via your Wireless Router administrator panel. You can access that by:

Start > Run > Cmd > ipconfig/all

Copy your Default Gateway address and paste this in your brower's address bar.

You should be prompted for a username/password. These will be given to you by your ISP when you had your router delivered or you can look underneath your router for a little sticker displaying your username and password.

You should be able to access the router homepage and have a look at additional DNS settings usually under 'Settings' or 'Device Settings'.

it depends

The name of the protocol is "HTTP". Short for HyperText Transport Protocol.

Typically you would need a gateway for this purpose, because the protocols are very different. In my HP server, for example, I have two NIC cards; one of the NICs connects to a Token Ring network and the other connects to an Ethernet network.

The software in the HP server (gateway) manages the translation between the two different types of networks.

Connects the router to a single broadcast address. e.g. LAN

Any time-slot on any GSM radio channel assigned to GPRS usage is defined as a Packet. Data CHannel(PDCH).

8 days

Above answer is not exactly correct. The default period of time (T1) is 1/2 the time of the original DHCP lease time. So if you have a lease time of 2 days then the first attempt to renew the lease will be in 1 day.

Since 157.54.4.201 falls in the class B address range the default subnet mask would be:

255.255.0.0

128 - 191 is a class B address.

A parallel cable carries multiple signals while a co-axial cable typically carries a single signal, but that signal can be modulated to carry more than one channel of information.

A parallel cable typically carried 8, 16 or even 32 data lines as well as clock and control lines.

In the early days of computing parallel interfaces could transfer whole bytes or words simultaneously, so they were frequently faster than the equivalent serial interfaces which were available at that time. Early PCs, data storage devices and digital television equipment made use of high speed parallel connections to offer fast data rates whilst requiring a lot less processing power compared to serial connections.

In recent years, local and wide area networking - using wireless links and telephone based connections - have seen major developments in serial interfacing technology to increase overall data throughput, so that today's serial cables and interfaces are much faster than most parallel cable solutions. Furthermore parallel solutions are not compatible with the serial format of wireless and wired Ethernet, so offer little benefit compared to using either co-ax or twisted pair serial cables.

A switch is a network connectivity device and a host is a computer system (client) on a network.

A POTS (Plain Old Telephone Service) line is full duplex over a single twisted pair because both the transmitter and the receiver are in series. Both parties can talk at the same time, and the signals are simply added together. Things do work a bit differently in modern telephone systems, but the full-duplex concept remains for backward compatibility.

There are many protocols that can be used over serial ports. The most common ones are RS-232 and Z-Modem for file transfers.

Well, copper is much cheaper then silver, gold and metal. which is why it is used to make coins.

Copper is less essential for the economy. for example if we molt all of our gold then the jewelry shops will go bankrupt mostly.

also copper takes less time to fossilize, as for gold takes millions of years

longer cable lengths have greater signal attenuation

In a LAN, the use of a networking switch can minimize problems with packet sniffing by implementing IPsec at layer 3which encrypts transmissions across the network link.

(These damn ITT tech questions can be a pain sometimes, eh?)

In october of 1965 Thomas Marill and Lawrence Roberts set up the first wide area network. The wide area network they created connected MIT and a corporation located in California.

The main advantage to DNS is that Internet users only need to know the URL instead of the IP address to get to a website. The main disadvantage with DNS is that there may be problems finding the correct website when the IP address of that site changes.

The RIPE Network Coordination Centre provides internet resource allocations, registration services, and coordination activities that support the use of internet worldwide.

Well, that reminds me of my engineering course :)

Well, it's a mesh topology.

The process is any type of software running on a computer. Service refers to process that runs in the background but does not interact with the desktop. On the other hand, application refers to the design to perform a function like video editing and word processing.

server option means that the option we can able to set the default gate way address mans router address wins, dns , etc............and the address we set there is linked with all the scopes or all the ranges. But scope option means that "we take a particular scope and set a specified address ( gateway address) and that address is linked with that scope only

yes u can
