How does the 3 way handshake works?
in oneway hand shake only server will verify the certificate details,ie client details
in 2 way both server and lient details are going to be verify ie in 2 way,server by client and client details by server
How does a network bridge work?
A network bridge is a device which connects two parts of a network together at the data link layer (layer 2 of the OSI model).
Network bridges work similarly to network switches, but the traffic is managed differently. A bridge will only send traffic from one side to the other if it is going to a destination on the other side. This is different to a layer 1 switch which sends all traffic from either side. Sometimes network bridges are called layer 2 switches.
Since they need to look at the contents of the traffic going into them, they are much more complicated than a hub or repeater
What is the world wide network that connects hundreds of thousands of smaller network?
the internet and the world wide web
connectionless protocols - transport layer
You have to shut down your computer and open up the case
1. Find the slot that fits with your nic
2. take the metal slip blocking the slot, out of your computer
3. Insert your nic into the Slot at a 45 degree angle
4. Seat the Nic( Insert it completely)
5. check that it is seated correctly
6. close your computer back up
7.Reboot(Turn on) your computer
What are the Benefits of server side processing?
This question is too vague to answer properly. If you are using server side processing to execute scripts on the server or access database information, it is essential. If you are using it strictly for the include feature, it depends on the size of your website.
SSI saves you time when updating common elements on each page of your website, but the creation and maintenance of the included files can be difficult and time consuming. Since the included files are usually incomplete code snippets, many editors and browsers will not handle them properly. This can restrict you to using something like notepad to maintain your site. If you want to view your results you will either have to upload them to a server first or run server software on your local PC.
If your site is only a few pages, the extra hassle is not worth it, if it is huge, it is worth it. The crossover point is up to you.
How many wan links required t create a full mesh of connections between five remote site?
The equation to solve for the number of connections c is c=(n*(n-1))/2. So a network of 10 computers would need (10*9)/2 or 45 links
What is the maximum data rate for IEEE 1394a?
How meany classification of fire extinguishers are there
Who is responsible for setting up and manging a computer or network of computers?
The one responsible for managing a computer or network of computers are called a network administrator.
What is the janoskians address?
29 Milverton Street, Camberwell Victoria I think its the brook brothers house im not sure! it looks like a brook brothers house.
IP is needed for all Internet communications, not just when you browse the Internet with Internet Explorer. The IP address is basically the address that distinguishes where you want to send information to, and from where the information comes. There simply has to be a way to distinguish with which of the millions of computers in the World you want to communicate.
What are two common types of static routes in routing tables?
ils y a deux types: table statique et table dynamique
Translation - There are 2 types. Static table, and dynamic table.
What are the reasons for using a proxy server?
Back in the day, Proxies was used to virtually connect computers to networks that wasn't physically at the network area. As in you have a computer in area A and a computer in area B, you would use a proxy to link both of those computers so it seems like computer B is within area As network, or vise versa. Computer A would also be running a encrypted layer, if it has, so if monitored from area B, all they would see a lot of bandwidth being used from one connection.
Today, people use a more "user-friendly" service that has surpassed the use of proxies, but still uses its technologies, VPNs (Virtual Private Networks) are networks dedicated to only be connected to and its computers to only be used for monitoring services. VPNs use more resources this way by the computers just standing in idle for connections to come in, while proxies; theres already a computer within the network at all times on the network running for its purpose waiting for a other computer to come in to do the same thing.
Lets some some analogies.
Proxies:
Lets say a whole bunch of your friends are at a party, but you can not come for some reason. So you choose to just buzz in through a webcam, and just hang out like that.
People come by the computer and look into the webcam to talk to you, chat, socialize through the computer. Your at a different location, while the entire "Party/Network" is over in a other location.
VPNs:
The room is empty. Not a soul to be seen, just computers lined with computers. Then you, and all your friends connect from etirely diffrent locations, to this one "Party/Network" And you all socialized like that.
What occurs at the Network Interface layer of the TCPIP model?
The network access layer equivalent to the physical and data link layers of the osi model. basically this layer defines how data is physically sent through the network.
There are several OSI and TCP/IP model video tutorials online.
reassembles
A router boots and enters setup mode What is the reason for this?
The configuration file is missing from NVRAM
What is the number of computers connected to novell netware?
there are how many computers you can get connected to
How do you get the Broadcast address of an IP address?
The address before the next valid network address will be the broadcast address
For Example:192.168.1.64
the broadcast address is 192.168.1.127
Bridge work in which layer in osi layer?
Gateways work on all seven OSI layers . The main job of a gateway is to convert protocols among communications networks.
What are some major limitations of twisted-pair wire?
Obviously the hardware router of wi fi signal has a malfunction. So a process known as magnetic repulsion is used so that the twisted pairs oof wires do not interfere within the wireless networking.
P.s these are not the disadvantages
