ftp- file transfer protocol, port 23 i beileve. Allows users to upload/download files w/o alot of difficulties.
hub- network device, unroutable and just forwards packets, doesnt check for errors or does not contain a routing table.
ip- internet protocol, addressing convention used to uniquely identify computers that connect to the internet and over a network
http: protocol used for web browsers along with https, uses port 80.
isp- internet service provider. Who supports your internet service
LAN- Local area network. A network that uses 1 ip address that is split between nodes and shared. Also can contain shared resources.
Upload- Process of taking information from your computer and loading it to another source PC/server, hence why download you are getting info from another pc/server..
DSL- Digital subscriber line, uses phone lines and special channels to communicate on which speed up the standard phone line speed. standard speed is 786Kbp/s.. Comes in diff. flavors ADSL, VDSL, etc..
Ethernet- standard of networking used most commonly, easiest to set up, alot of the time for wired ethernet, PnP.
Cable Modem- Takes Coax cable getting signal from cable ISP and modulates/demodulates signals going to and from computer. Signals from ISP are analog so the modem must modulate to digital for the computer to read it and other way around for PC to ISP.
Bandwith- Multiple signal channel output over a network medium
instaed of baseband which is one signal back and forth.
Mac address- Burnt in address assigned to your Network Card/router/modem from factory. Unique identifier for your computer network device. Only way to change this address is to emulate or spoof this through the transport layer.
Network address- Depending on what class IP address (A-D) the network address will be part of the ip address. For instance; a class A ip address of 82.184.24.20 would have a network address of 82.0.0.0 and host address of x.184.24.20
IP address- address assigned via DHCP or staticly using Internte protocol.
modem- modulates/demodulates digital and analog signals
node- any machine that aquires an ip address on a network.
octet- in an ip address, the numbers are divided into 4 octets seperated by periods.
port number- ports used by UDP and TCP for incoming/outgoing traffic
protocol- set of defined rules for a network medium
repeater- takes analog/digital signals and ouputs a stronger signal from the signal received through the router, same concept as an amplifier.
router- routable network device, has power to host DHCP/DNS server, splits ip address into private addresses and uses NAT to share internet connection. Can contain a routing table and many extra useful features for networking.
switch- uses ARP (address resolution protocol) to route information to/from client/servers. ARP is process of matching ip address with mac address and RARP is also available to match mac address to ip address.
tcp/ip- standard internet protcol that creates a transmission and a means of addressing in one. Easiest protocol to configure and very reliable.
url- format web pages are saved in
WAN- Wide Area Network, Network over a undefined length that are somehow connected through segments, subnets, or domains.
rj45 connector- uses 4 pairs of twisted wires to send/receive signal where as rj11 uses 2 or 3, i forget.
cat 5 e- standard of cable that 100base networks use, throughput around 100Mbp/s, maximum length 100 meters.
peer to peer- No centralized server, most commonly known as a workgroup and shouldn't contain more then 10 users.
client/server- centralized server, most commonly known as a domain. Multiple types of resource sharing and server services are applied in most cases, with some kind of database that organized the domain(s). For instance Active Directory for Server versions of Windows.

You're on yer own. You've got 2 minutes per question. I do believe you're answering your own questions to earn yourself some points. I think I'll stick you both on my watchlist, after i report you both.
