CompTIA Network+ (N10-007 Topologies

Physical Bus Topology

The following is a representation of physical bus topology. The nodes are connected to a single cable with terminators at each end of the cable. This is also a logical bus topology as the signal transmitted from one node is sent to all the other nodes.

Physical Ring - Logical Bus

This is a physical ring that uses tokens. Only one device has the token at a point in time. The data only flows in one direction.

IPv4 Subnetting - Videos

IPv4 Subnetting: 3rd & 4th octets

Here are a series of videos to help you understand subnetting. 

There is a 5 part set of videos to take you from understanding binary to basic subnetting.

Then we have added videos to help with understanding subnetting in the 3rd octet.

Other videos are basic subnetting problems and worded subnetting questions. More videos to come in the near future.

Here is the link to the videos:

Network Tools: Know what they look like and what they do.

Punch down tool

Punch down tool. Used to connect twisted pair cable to a 110 block, wall plate, and patch panel

Crimper

Crimping tool for twisted pair cabling. Used to attach RJ-11 / RJ-45 connectors to twisted pair cabling

Tone generator

Tone generator: used to trace cables. Comes in handy when the wall plates and or cables are not properly labeled.

Loopback adapter: used to test the functionality of the network card and test the TCP/IP protocol stack when an ethernet cable is not available from the DHCP server.

Network+ / N10-007 Test Prep

This is the first day of setup for the study material for the Network+ N10-007 exam. This will be a work in progress as I am a Network Admin and a Technical Instructor specializing in CompTIA boot camps.

On the right-hand side of the page will be linked to other pages. This first one is for the acronyms for this exam. It's a flashcard program that has multiple features. I will add a little each day.
