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 are the advantages of switch?
Switch is faster than HUB. If you are using managed switch you can create VLAN, you can secure ports and many other things.
Why does it take so long to download an ISO?
It all depends on the size of the file, and your internet connection. ISO files are large compressed image files used to boot CD/DVD's and there installed files. They can be up to 10 gigs easily. With a 100KB line, 4 gigs will take a few hours. With a 5KB line like dial up it will takes weeks.
What network of paths connected to scattered communities of new Spain?
britian, france, germany, and northwest passage
What types of errors will simple parity not detect?
Simple parity can not correct multiple errors. If more than one error exists at a time, then simple parity can not calculate the missing data.
Does LAN connection need a telephone line?
no need of telephone line for LAN networking. for LAN we ethernet card and other networking devices like hub, switch. for internet connection u need telephone line
A Lan is a shared network of multiple systems. You can have a LAN which does not have Internet access and only supports Print/File Sharing. You need one router to assign IP addresses using DHCP and if more connection are required, just add switches.
To give the LAN Internet access, you need an ISP connection and a modem. The existing router then connects to the modem.
The ISP connection (today 2008) can be DSL, FiOS (over a phone line) or Cable.
A dial-up connection can be shared on a LAN, but today that is a very poor choice and would not be connected as described above.
c=wavelength*frequency
f=c/λ
A subnet created by moving the subnet boundary to the leftis called?
Moving a subnet to left to save bits is known as a supernet.
Something that no one else knows about you like what you do in your free time, etc.
How is TCP connection-oriented but IP connectionless?
TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged.that connection is virtual only...
Topology network formula and for example?
Only the formula required is for mesh topology. i.e.
The number of connections in a full mesh = n(n - 1) / 2.
How can resources be difficult to share?
it can be difficult to share because humans depend on the enviroment for resources
First of all, use a network scanner and scan your network and it'll give you a list of every active IP on the network and the hostname of the device ( name ). I recommend an app on the appstore called "iNet" free and fast. It scans whatever subnet your on 192.x or 10.x 184.x etc. It is very useful for big networks for finding computers. Another way is to open your router webpage and it should have a list of every connected client on the network and their IP along with hostnames and mac address.Takes more time using these steps provided but didn't delete it.
1st option is to run ipconfig on each computer and it will tell you the ip address of the computer you are on. To get the name of the computer you can go to the network configuration settings which I will explain in a bit how to get to.
2nd option type in the IP address of the router in the web browser of the one of the computers connected to it, log in to the router with the username and password you used to set it up with, and depending on the router you have you're going to want to look at the log or look around in the different settings to see if you can't find a list of currently connected devices almost eveyr router I've seen to date has had a list somewhere of the devices connected to it
anyways back to option 1....in order to run ipconfig on your computer go to Start menu -> Run (or hold the windows key and press r) type in ipconfig in the box that pops up....if that doesn't work then try typing cmd in the box....you should get an msdos looking window that pops up....from there type in ipconfig....after that look for the IP Address it will be clearly listed there
now as for getting to the name of the computers....I'm not sure about other operating systems but I'm pretty sure it's quite similar across all windows operating systems but I will give you the exact instructions from Windows 2000 Professional which is what OS I happen to run:
1. right click on the My Computer icon which is located on the desktop
2. left click on properties
3. Go to the Network Identification tab
4. Click the properties button
5. Look at the value in the Computer Name box
6. Now you know what the computer's name is
Well, I hope this helped
What processes do networking protocol suites describe?
Networking protocol suites describe processes such as:
-The format or structure of the message
-The method by which networking devices share information about pathways with other networks
-How and when error and system messages are passed between devices
-The setup and termination of data transfer sessions
What is the main network protocol used to communicate between Windows 7 computers?
Without a doubt, TCP/IP.
peers means friends.
Your peers are the people at the same level as you, not necessarily just students or friends, it could also refer to workmates, junior managers, similar types of worker, etc.
Why is a switch called as layer 2 device?
because one layer is the electrical part, and the other layer is the place where the switch is on.
there are three types of switching techniques
1) circuit switcching
2) Packet switching
3)Message switching
