How do you begin to become a network engineer?
Network engineers are the backbone of the computer infrastructure of a company. Large companies are able to employ many network engineers, while smaller ones often need to hire a consulting group. These engineers update a computer network and fix problems whenever they arise. If you want to become a network engineer, you need a love of computers as well as terrific problem-solving skills. == Bachelor's degree in computer engineering or computer science. == Step 1 Study a computer-related field in college. Despite the name, network engineering doesn't require an engineering degree. You could also study a completely different major and minor in information technology.
Step 2 Get a job at your university's office of information technology. Most large schools hire student IT support to work in both classroom and dorm environments. These jobs generally require 1 to 2 years of computer-related study and are a great way to build your resume.
Step 3 Learn to use all different kinds of operating systems. Most network administration computers use a different operating system than the office computers and company laptops. You'll need to be familiar with all of them in order to become a network engineer.
Step 4 Look for an internship with the IT department of a company or with a computer consulting firm. The number of students majoring in computer-related fields is growing, so you will need experience to help you stand out from the pack.
Step 5 Work on your communication skills. If you become a network engineer, you'll often have to work with people who aren't as tech-savvy as you. You should learn to explain computer problems in straightforward language. Consider taking an acting, improv or speech class to hone your communication skills.

When sending information over a local area network, to a specific computer, the MAC address of the destination must be known. ARP - the address resolution protocol - takes care of that. With it, you can ask for the MAC address that corresponds to a specific IP address.

Cat5e rated for 100Mbit, and Cat6 rated for 1000Mbit
Maintaining awareness of potential threats to information and information systems
How does underwater wireless sensor network work?
They use acoustic modems, which is a like a modem for your computer but rather than sending data as electrical signals through the copper phone wires, acoustic modems send data as acoustic waves under water.
Why is NTP required in an NFS network?
It's not. It's beneficial for making sure that file creation and modification times are correct, but it's not required. NTP is also beneficial if Kerberos authentication is used for the NFS server. Kerberos uses a time-stamped ticket system; each ticket is only good for a specified time period, typically five minutes. Therefore, all machines involved need to have their clocks set to be approximately the same. NTP is beneficial for this as well, but again, it is not required, and can be accomplished in many other ways.
How can one use a MAC address lookup to find a vendor?
Find the MAC address of your Ethernet or Bluetooth device and visit a site which will lookup the associated vendor. Enter in the alphanumeric letters associated with the vendor.
Virtual path identifier is used to identify the virtual circuits used to deliver cells in the ATM network.
Explain the differences between the running-config and the startup-config?
The statup-config is the configuration that is loaded when the router boots or powers up.
The runnning-config is the current configuration in the router. It may have been modified since the last boot and so might be different.
Having these two provides a nice safety feature. Changes can be made to the running-config and if something badly goes wrong, you can restart the router and get back to the configuration without the changes.
