I got so busy watching Star Trek that I forgot to write this blog. I want to keep this entry brief because I have fallen behind, but will offer up a quick lesson from my computer science class on memory. Basically all a computer needs is a place to write down bits of information in the form of ones and zeros, and then it needs to be able to read that information later. The brain, I gather, is more like making neural connections and forming stronger links the more information is used. Computer processors have cache memory and random access memory which are places the computer stores the more frequently used  information, like running applications, or recent calls lists.

What does a memory circuit look like? We'll here is what is diagram for a circuit, called an R-S Flip Flop, looks like. The tan shield thingies are Nor logic gates. I forgot what that means, but you should do what my TA in college told me to do, just Google it. OK, nor is short hand for not or, which is grammatically incorrect but logically sound. It means that if there is a positive charge or a live current, represented by a 1, sent through the gate, or latch, then a 0 or null charge will pass through the other side, then it will send that 0 signal up to the Reset side which will pass a 1 on through, and this is how a state, or a 1 or 0 is stored in your computer.

S stands for set, R stands for reset. The Q with a line over it is not Q, or the opposite of Q. In conclusion, Pete and re-Pete are in a boat, Pete jumped out and who was left?" Not Pete. Good night.
