ITTech Journal entry
Feb/6/2013
So today was a great day, We met one of the stake holders, He
really struck me as a brilliant gentleman.
The
man has many plans for the IT structure out here!
Now moving onto what I have learned today.
I will start out with by diving into the RJ( Registered jack) the
two most common jacks are RJ-11 and RJ-45 RJ-11 is a phone jack, You will find
it in your office or home, The type of cables are called Satin.
The Rj-45 connectors are much larger then the RJ-11 connectors,
And more commonly found on the ethernet networks, they use twisted-pair
cabling. Majority of NIC(Network Interface Card) have a RJ-45 jack on them. On
my final note about RJ's they have a small locking tab on them.
Moving onto Video Display Cables and Connectors
The DVI Connector offer much higher performance than the original
digital standards, Such as CGA and EGA. This connector will appear like a D-SUB
connector, but it is very much so different, The number of pins are far greater
then the D-SUB connector, and the pins are asymmeterical in their placement on
the connector. I almost forgot to mention the DVI was a jump from Analog
connectors to Digital, The reason for this fact is because all adapters and
digital display technologies are now dealing with Digital information.
DVI Subcategories
DVI-A DVI-D DVI-I
The DVI-A and DVI-I
connectors come in two different varieties, single link and dual link. The dual
link option has more conductors(6 of them to be exact) then a single link, The
extra link accomodates higher speeds and signal quality, This additional Link
can also be used to increase your resolution from 1920x1080 to 2048x1536 for
devices with a 16:9 aspect ratio.
In the end you can just
purchase a adapter, because these connectors are pin compatible.
I will end this entry into my
Blog by saying this, I can see a bright future for my self in the IT Industry.
