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.

The method to link 2 computers with serial cable?
To link 2 computers you should have cross cable. Because Serial cable is user to connect 2 or more dissimilar devices. To connect 2 similar devices like computers, Hubs, Switches you should use Cross cable only.
In Serial cable 4 pairs of cables are their, 2 pairs for Transmitting and 2 pairs for Receiving the Data. If you use serial cable to connect 2 computers, Conflict will happen while sending and receiving the data. In cross cable 2 pairs of cable will be in a different order so conflict won't happen. So use Cross Cable while connecting 2 similar devices.
Which rfc contains eigrp routing protocol?
this is a cisco propreitory protocol is not available for rfc
What takes place at the session layer?
In the OSI model, the session layer is in charge of coordinating various applications as they are communicating with different hosts. This layer establishes, manages and terminates sessions of the applications accordingly.

What is the difference between FTP and TFTP?
The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP.
The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offer by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.
If you change ftp port does it stop access?
Usually, if you change the port in a server's configuration file, you will have to stop and restart its daemon or service for the changes to take effect. Changing the FTP port would not stop access, butyou would probably have to specify the port manually on any FTP client.
What is the correct order in which the STP components are chosen?
root bridge, root ports, designated ports, nondesignated ports
What does it mean for a wireless networking device to be Wi-Fi compliant?
By definition, a wireless networking device is Wi-Fi compliant. Wi-Fi is simply another name for wireless networking. There are different wireless networking standards that mostly determine the speed at which data can be transferred, but it sounds to me as though this statement of being compliant is just a fancy way to say that it is indeed a wireless device.
UPDATE: I have since learned, that WiFi compliant has to do with a consortium of several manufacturers, and that they have trademarked the name WiFi and work together to make sure that their products are interoperable.
In order to test a client server application, you need to know the following parameters:
1) First of all, you need to know the number of users who work on the application on an average.
2) you also need to know the peak load i.e. how many users at the max?
3) Bandwidth of the network connection.
4) Which action is most frequently done by the users.
etc.
All these parameters can be used to emulate the real scenario in run-time settings/controller.
Various scenarios can also be created in Controller to emulate the real-time scenarios.Â

To see whether load balancing is in effect, check the routing table. Load balancing is in effect if two or more routes are associated with the same destination.
The show ip route command reveals that the destination network 192.168.6.0 is available through 192.168.2.1 (Serial 0/0/0) and 192.168.4.1 (Serial 0/0/1).
What does www stand for at the being of the web address?
The "WWW" at the beginning of an address stands for World Wide Web.

It's a network only without cables. The Access point(sometimes built into the router) is the hub of the network. Most wireless devices DO NOT transmit to each other but to the hub that routes the traffic to the other devices. This is usually done on a certain frequency (fixed) determined by the routers configuration.
In electrical installation why do you need to ensure the cables are not twisted or plaited?
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
Identify the connector that can be used to connect RG6 cables?
The "F" connector is the most common type that is used on RG6 cable. This is the universal connector for home use of RG6 with antennas, CATV, satellite, and consumer electronics.
What are the four basic steps of troubleshooting a modem?
Step 1 - Analyze the circuit
First, see if the circuit operates correctly. If the circuit operates correctly, there is no need to troubleshoot and this would be the last step. If the circuit does NOT operate correctly, then you must go to the next step.
Step 2 - Check the setup
If the circuit is not operating correctly, check to see if you have overlooked something simple. Check connections and buttons to see if they are set correctly. If you checked the setup and the setup is good, but the the circuit does not operate correctly, go on to step 3.
Step 3 - Calculate and measure values
First, calculate to determine the values that should be present in the circuit that is not working properly by using I = V/R. Make voltage, current or resistance measurements. In most cases, the voltage measurements are made first. Voltage measurements provide useful information about the circuit and are made without breaking the circuit. If more information is needed, make current or resistance measurements. Remember, the circuit MUST be broken to make these measurements. Make as many measurements as needed. As the pieces of the puzzle begin to fall into place, identifying the fault becomes easier.
Step 4 - Check the results
Compare the calculated to measured values. You should have enough information to identify the fault. Replace the faulted component and perform step 1 again. If the circuit operates properly, the circuit is fixed.

Each host on a network has a unique ip address with how many bytes?
A bit is a 1 or a 0 to the computer. A byte is 8 bits. A byte can represent any number from 0-256.
for example: 00000001 = 1 / 00000010 = 2 / 00000100 = 4 / 00000111 = 7 (4+2+1).
This probably wont make you understand it but anyway an IP address like 192.168.1.101 consists of 4 bytes, or 32 bits (8 * 4). Same thing with 154.12.154.254 or 1.1.1.1
