You are currently working for Surebank, a mid-size financial institution. The organization has approximately 80 people working in their main location where your office is located. The bank also has two branch locations. You have been very successful in your career as a Network Operation Specialist, serving at the help desk, assisting many users with routine problems with their desktop PC's and the company software. Your supervisor, the Network Administrator, was recently fired because of poor attendance. As you are the senior NOS and have performed very capably, you have been appointed as the Interim Network Administrator. If you do well, the interim position could become permanent for you.
Windows 2000 operating system and the Microsoft Office 2000 Suite is on all of the desktop computers (each staff member has a PC). These are the two primary applications you Explain to your team the differences between routers and switches. Compare them and list the pros and cons of using each type of hardware.

The staff also uses a text-based interface to the financial system that operates on a mini-main frame similar to a UNIX machine. This interface is supported by consultants. You only need to coordinate the support calls for this software.
Each branch office has only two computers. Those computers are connected to the main office over a Frame Relay network that is supported by your local Internet Service Provider.
When you moved into your new office, you discovered that there is no network inventory, no network diagram, and very little information on how to maintain the network. You believe that the former Network Administrator took all of this information with him in retaliation for being terminated. You are not allowed to contact him, so you are on your own to learn and recreate the information you will need to be successful in this new position.
You will be able to use Internet search engines as well as have access to vendor information and technical resources to assist you in the work.
The main office computers are connected via an Ethernet network and a Token Ring network. Your predecessor was working on a presentation to your boss about having the Token Ring network replaced and converted to Ethernet. You have not been able to find the presentation so you will need to redo his work. In the coming weeks, you will need to both maintain current projects and systems, as well as take on any projects management asks of you.

Most routers are a combination Ethernet switch (or hub) and Network Address Translator. They usually include a Dynamic Host Configuration Protocol (DHCP) server, Domain Name Service (DNS) proxy server, and a hardware firewall to protect the Local Area Network (LAN) from malicious intrusion from the Internet.
All routers have a Wide Area Network (WAN) Port. This port connects to the to a DSL or cable MODEM for broadband service (e.g., the Internet) and is usually a 10 MHz 10BASET Ethernet port. A 10 MHz WAN port is sufficient for cable and DSL MODEMs as these devices transfer data at rate that is a fraction of 10 MHz.
Many recent broadband routers are combination routers/Ethernet switch (or hub) that have multiple Ethernet ports to connect more than one PC to form a LAN. These ports allow the PCs to share the WAN port/broadband Internet connection and perform LAN functions, such as Windows file and printer sharing. The LAN ports are usually 100 MHz 100 BASE-TX ...
