Day 9

Day 9

  So today was actually a very good day, I did know some of the stuff we were being taught. But of course I learnt much more then I had hoped!

Where should I start, How about Ram types and specs.
Ram is a group of semi conductors- semi conductors are chips that are soldered to the board of Ram it self. Ram is volatile. Constant electrical charge and a refresh charge keep the data in the ram it self, This refresh can cause delays on the CPU How ever modern CPUs are clever.
The ram goes and grabs the data and takes it down to the EBD so the CPU can act on the code; The RAM uses source codes and the CPU uses op codes address bus and external data.

 I will skip a few obsolete Ram types, and jump to DDR3 the god send to anyone who uses a Computer.

DDR3 not to be mistaken for GDR3; It is way more useful, It has higher speeds, 30% Less power comes with 240 D PINS and 204 L pins; DDR3 also has a doubled buffer from 4 bits to 8 bits extended memory profile, Ideal for overclocking your rig.
 It comes with Higher density memory chips as well. Sooner then later there will be a 16 gb on ddr3, and some mobos can do triple channel interjectory; Which quadruples clockspeed because the buffer size is increased so it grabs as much data every clock cycle

Well my damn nose wont stop running and i'm hacking like a witch, so ill end this with one question.
 Why did it take so long for dual architecture to come along for RAM?

Class 8

Class 8

So today in class we had gone over quite a bit of stuff I had some knowledge of; So todays blog may be shorter then expected.
We had reviewed and gone over creating a word document, and enabling tracking and editing on it, Then emailed the doc. to a class mate. And then we had to edit it and add one comment to it before then re-sending the doc. to our mate.
Over all the feature is really useful for future references.

I had also found it very informative learning about Uninterruptible Power Supply (UPS) and how they work.
This aparatus  is made to be a emergency PSU meant for but not soley  blackouts and or brownouts; UPS far exceeds backup emergency power system or a standby generator because during a brownout or blackout the device is instantaneous(It has a battery). Now these UPS' come in many shapes and or sizes, But you can get one to fit your very own home work space desktop!

One question I have in regards to all this, Is why are UPS not in more common use in this day and age.

Now I would like to type more, of course to re iterate this into my brain one more time. But sadly i'm starving;  So I have to log off, if anyone is reading these, Leave a comment or some trace of a view.

Day 7

So today all internet problems aside at class; I learnt quite about about hardware. Mainly I found it very interesting how the MOBO functions.
 Let me go a bit more in depth; To start out I learnt about embedded wires on the  mobo are called traces(not be confused with the magnetic flux drives, or the runs) These traces make up the buses of the system, The layers of the printed circuits, The mobo is a printed circuit board [PCB] 4+ layers thick currently.Why do you want more layers ? Because you end up with a smaller card.

One last tid bit of info here, In 1980's IBM manufactured the first AT form factor; The number one inherit problem with the first AFF was the fact that it only had two dedicated connections for the keyboard and the mouse. Of course naturally with time and evolution we needed more Connections, Which then leads me to say there was variations I will not go too far into the two variations but here they are NLX and LPX.

So I hope someone out there gains some information or intelligence from my blog.

In the past week of my course, I learnt many  many things.
The most important would have to be about hard drives; Mainly how they work with magnetic actuator arms; And how the hard drives have a parking spot for the actuator arm.
In the past the actuator arms were connected to stepping motors.
One of the downfalls to these were the heat it would corrupt data, Now they are equipped with linear motors with voice coils.
 The linear motors increase accuracy of the actuator arm.
I know to the average person this is not very usefull but to me this is very good information.
