Computer Networking

Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

What is offline file share?

Offline Files allows you to keep using network files, folders, and applications when disconnected from the network. To users, this is transparent; offline, they'll have the same access permissions to the files and folders that are available when they're connected to the network. Best of all, when they reconnect, all the changes they've made to those files will be made to the files on the network, via offline file synchronization. Any file or folder that is shared on a Microsoft network can be made available offline, as long as the computer on which it's stored supports SMB-based file and printer sharing. (This includes all Windows 9x/NT4/2000/XP computers.)

Can you view your router log?

It's purely depends on your router. Some more expensive routers allow to do such stuff. While cheaper counterparts are not capable of such things.

What Speed at which computer modem can transmit information over phone line?

Actually, what LewisMiller said is not completely accurate. While dial-up modems are capable of 56Kbps, the traditional phone line is capable of only 53Kbps. Thus, the download speed is actually only a maximum of 53Kbps, often lower due to noise on the lines or other issues. Back in the day when I used dial-up, most often my US Robotics Sportster saw speeds of 33.6Kbps to 48Kbps. Further, upload speed is generally slower than the 53Kbps speed maximum: most frequently, the upload speed is limited to 33.6Kbps, sometimes only 28.8Kbps (depending on the capabilities of the modems at both ends of the dial-up connection).

As for DSL, a standard ADSL service is actually 1.5Mbps, not 112Kbps, and the lowest "fractional DSL" speed I have encountered is 256Kbps. Years ago, there was another service called ISDN that was most often offered in 64Kbps and 128Kbps speeds but it was not widely adopted, especially since cable modems and DSL services started making headway around the same time. It may be of this service that LewisMiller may have been thinking.

What are the advantages to using a strict NAT over an open NAT?

With an open nat it's possible to host online games and get into games quicker

A network technician must reduce the amount of broadcast traffic on the network while maintaining full connectivity between all different network segments Which device should the administrator deploy?

This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects.

But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.

What is the max distance of a Wide area network?

The max distance of a WAN, is not limited any longer, because a WAN is connected over terrain and under or over water ways. At any give time a WAN can be as large as the seven continents or as small as one state.

What is an advantage of using a loop back interface on a router with OSPF enabled?

The main advantage of running a loop back interface with OSPF enabled on the router is that there is minimal cost. The IP address will also remain stable in this set up.

Do you have to use both a modem and a router together?

A cable internet customer can use just a modem if they are connecting a single device to the Internet, such as a desktop computer. Many customers now have a plurality of devices they would like to connect to the Internet at once, such as video game consoles, televisions, media centers, laptops, tablets, computers, and phones. In this case, a device that operates as a router is necessary.

The modem provides connectivity for a single device to the Internet, while the router provides a network to many devices in the same area; the combination of the two allows many devices to access the Internet at the same time. Cable operators may now provide a single device that operates as a modem and a router, in which case, only one device is necessary, since it fulfills both roles at once. Technically, the customer still has a modem and a router, but it is housed in a single device, reducing power usage and providing a smaller footprint.

How does a pbx work?

A PBX (Private Branch eXchange) is a phone system switch that can connect many internal telephone lines to a few external PS TN lines. With a PBX all of the in house phones connect using designated extension, usually just a few digits - it can also connect any extension with an outside line and any outside caller can make a direct call to any extension using a set prefix followed by the extension number. This function and other capabilities like answering service, call transferring and collecting of call statistics is handled by integrated software.

Could you explain what the different between Just and Only?

How can personal area network's eliminate redundancy in electronic devices?

Personal area networks eliminate redundancy in electronic devices by allowing sharing between the users. Examples of electronic devices that can be shared are plotters, printers and scanners.

How does a network traffic monitor work?

A network traffic monitor basically analyzes the network usage in local areas and then provides you with statistics of the upload and download rates. It does this by monitoring IP addresses between your local area and the internet.

WHAT IS THE FAMOUS server monitoring software?

"Enter Dyson. I'm sure you have seen the advertisements with James Dyson proclaiming that his invention is the best, because the vacuum never loses suction. The problem is that I just wasn't willing to part with $400-600 for a floor cleaner, no matter how fancy its cyclone technology promised to be."

What is pure networks platform service?

It is a program to assist you in setting up your home network for things such as printer sharing. If you do not know where it came from, it is often bundled in with routers from dlink and other companies.

If you are asking if you can/should remove it from your computer and startup then the answer would be yes if you have no plans to use it.
