4. Difference between Cat 5, Cat 5e and Cat 6?
Can handle 10/100 Mbps speeds (Fast Ethernet) up to 100 MHz bandwidth.
Very slow and obsolete compared to new speeds out now
Cat 5e:
Currently the most commonly used in new installations
Better at preventing signals on different circuits/channels from interfering
Can handle 1000 Mbps speeds at 100 MHz.
Cat 6:
Capable to handle up to 10 gigabit Ethernet at 250 MHz
Has internal separator that isolates pairs from one another

5. What are pros and cons of fiber optic cables?
Offers much larger transmission distance than copper cabling
Glass fiber costs have fallen
Much more bandwidth per cable than copper cables
Once fiber’s installed, no need to re-install new cables for awhile
Fiber’s immune to external radio frequency or electromagnetic interference, unlike copper 
Requires special training and equipment to fix
If you compare patch cabling and network switches, fiber is more expensive

6. What is Multi- mode fiber?
Has large diametral core allowing multiple modes of light to transmit
So, number of light reflections created as the light passes through increases
Creating the ability for more data to pass through at a given time
Because of the high dispersion and attenuation rate, the quality of the signal is reduced over long distances
This application is usually used for short distance, data and audio/video applications in LANs
Multimode fiber is usually 50/125 and 62.5/125
Means that the core to cladding diameter ratio is 50 microns to 125 microns and 62.5 microns to 125 microns

7. Did touring the network facility increase or decrease your interest in Network Administration or Engineering as a possible career? Why?
Touring the network facility decreased my interest in Network Administration or engineering
There’s many different fundamental skills to be adept in, in order to succeed in this field
