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 function does the tcp protocol perform for a network connection?
it formats messages in segments
it reassembles messages at the destination
it creates a virtual circut between end user applications
What is a good switch for computer networks?
For home or office?
I'd recommend cisco for office and probably netgear for the home.
What are the disadvantages and advantages of using a wireless network at home?
Advantages:
1. no cables or wiring is involved.
2. easy for more than one PC to use the same Internet connection.
Disadvantages:
1. connection not as reliable as others since it is subject to interference or weak signals.
2. data may be viewed by others.
3. other people might use your Internet connection.
What type of special computer connects one Lan to another Lan?
A LAN Bridge. It is not a special computer per say.
A LAN bridge connects two or more LANs at layer two in the OSI network model. The LAN bridge receives packets from a LAN segment connected to one port and forwards them to another LAN segment connected to a different port. While a LAN bridge serves the purpose of extending network range, it also relieves the problem of congestion that multiple devices can cause on a single Ethernet segment.
How can you do inter vlan communication in a L3 D-link switch model is DGS 3612g?
inter_vlan routing on d'link DGS3612 is automatic,you just creates vlan and tag them to the port access and trunk
How does an Ethernet switch forward a broadcast frame?
it s connected by the bridge network connection
What does 2.2GHz800MHz mean for a computer processor?
2.2 GHz is a processor frequency, and 800 MHz is a FSB frequency. First defines how many operations can the processor does; second one defines how much information the processor transfers to other components of computer.
well, if they are all REAL switches and not hubs, there is probably really no need, unless capacity is an issue. If you have hubs, they are bottlenecks and force the computers to wait in line to transmit packets therefore less reliable and slower.
I would imagine you would see a decrease in performance if you had several computers all online requesting data at once, but most small home networks wouldn't even notice another couple of users surfing around.
yes i belive.
A physical topology diagram or network diagram, would show the actual physical devices on a network and how they connect to each other. This is often useful in determining how to expand a network or upgrade one.
There are several software packages that do an excellent job of producing the diagram, so it is unlikely this would be done manually. Plus, networks are dynamic enough that you would want some type of automated way of producing the diagram.
What are the extremely fast networking connections through which internet transmissions take place?
Backbones
How do I remove text while watching digital cable tv?
Press the "Captions" button on your remote until the text goes away.
Check in your BIOS. Pressing F2 at startup (it could be a different key, it'll be displayed on your screen) will bring you into it. In there, there should be a section labelled "Onboard Devices Configuration". Go into that, and it will list your devices. Ensure that Bluetooth is Enabled. Then press F10 to quit saving your changes and reboot your computer.
What is per vlan rapid spanning tree protocol?
Establishing STP per VLAN basis instead of entire VLAN network, so one STP for one VLAN and this for the security purpose where cisco extended its feature further naimg as PVSTP+,remember both are pvstp and pvstp+ are cisco proprietary and doesn't find use in other switches
Can you use a USB hub to setup a network?
A usb hub refers to USB devices, just basically give you extra usb plugs. This is not related to a network hub.
Network ID 10.10.128.0 and subnet mask 255.255.224.0 Which IP address range can be used?
Class A IP address.
Within the local network, every computer has to have a different IP address. These IP addresses have to be in the same subnet; usually this means that the first 3 bytes are the same.
