A hub uses straight throught cabling from clients to the hub, and uses a cross-over cable with the up-link ports to connect hubs to hubs.
Usually, the cabling is UTP (Unshielded Twisted Pair) wiring.
What is a fast but unreliable delivery protocol that operates on the Transport layer?
This would be UDP. The User Datagram Protocol. It has no error checking or correction or congestion measures.
How do an IP address and its subnet mask function together?
The subnet mask - expressed in binary - starts with a number of ones, followed by zeros. If (for example) the subnet mask is 255.255.255.0, this can also be written as /24 - that means that the first 24 bits are ones. In this example, that means that the first 24 bits of the IP address (in this case, exactly 3 bytes) are shared by all devices in the same subnet. So, if your IP address is 200.3.85.7, and the subnet mask is 255.255.255.0, all other computers in the same subnet will also start with 200.3.85.
What is a 3 gang 2 way switch?
3 gang means 3 individual switches in the same single unit.
2 way means each switch can be on or off.
How do you connect two computers without using LAN ports?
Get a USB Direct Connect Cable, it is a USB cable that has a special crossover and more to it. This makes the USB cable act like an old NULL Modem cable from the early days. You then plug it into the USB ports on each computer install the software drivers and then set up file sharing and whatever else it has you do to make it network and your good to go.
Do Not use a regular USB cable, you will fry things...
How can I know the person who hacked my network?
well... just be strange round the people u let in thier house and if they get real nervous then start asking them questions and then u found ur person :)
Difference between hub and switch?
A hub is a multi-port repeater, which means any signal from any connection is repeated to all other ports on the hub. This leads to more collisions as a result.
A switch is a multi-port bridge, and contains packet switching so that the message is only switched out the port of the destination device, not across all ports. Thus, the collisions are very small.
Switches and hubs can be used interchangeably in a network, with performance differences. The network does not know the difference.
Into which category or categories of e-commerce do P2P file-sharing networks fall?
It would fall in what appears to be a missing third category, customer to customer e-commerce.
What is the Purpose of TCP IP utilities?
The TCP/IP utilities are used to troubleshoot and diagnose issues with TCP/IP protocols. Ping is used to test connectivity between nodes in a network, netstat will show you ports in use and network connections, traceroute will trace the hops between routers/networks, nslookup and dig can be used to troubleshoot DNS problems.
RA(config-router)# network 172.16.1.0 0.0.0.15
What ip address would you use for a local network?

How do you ghost from hard disk to hard disk?
The best tool that I have ever used to ghost a hard drive image to another hard drive is Symantec's Ghost software. Simply set up two hard drives and boot from Ghost's cd. Setup the program to copy from one location to the other and you will end up with a perfect clone.
No, 2 year degrees are not accepted as University Degree you have to do a 4 year degree. in your case may be after doing 2 year master you will be considered as graduate internationally No, 2 year degrees are not accepted as University Degree you have to do a 4 year degree. in your case may be after doing 2 year master you will be considered as graduate internationally No, 2 year degrees are not accepted as University Degree you have to do a 4 year degree. in your case may be after doing 2 year master you will be considered as graduate internationally
It does not require any particular switch or router you can use either.
What is the subnet mask of 135.210.195.112?
This is a Class B address. So if classful addressing scheme we can say that the default mask of any Class B address is 255.255.0.0. But it may not be always this. There is a concept called VLSM (variable length subnet mask) with which we have the option to give different subnet masks.
Where do you get your subnet number from?
You (the network administrator) decide what subnet you need to use, depending on the available IP addresses, and how you want to divide your network into subnets (in case you use subnets).

IS mesh network topology the most expensive one?
Yes mesh is the most expensive because in a mesh environment, a cable runs from every computer to every other computer. If you have four computers , you must have six cables three coming from each computer to the other computers.
Fujitsu Siemens Scaleo T network Card driver.?
Try going to the vendor site to look for the download driver.
A NAK is a negative acknowledgment from DHCP. This can be done when an address renewal is refused by the DHCP server, or a duplicate IP address exists when requesting an offered IP address, among other reasons.
What TCPIP model layer does DHCP work at?
DHCP is a layer-4 protocol, most commonly transported over UDP. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client
If you are using a DHCP server, you are basically safe. It's a good practice to release all ip addresses after certain time especially if you have temporary computer in the network.
Advantages and disadvantages of tree network topology?
Some advantages of tree network topology include easy to set up and extend. It is also inexpensive. Its disadvantages, on the other hand, include limit on central cable length and number of nodes.
