today's the day when we left the coverage on the machine it's actually one we sorta like republican here although i'm not gonna republicans here i consider doing that we're going to republican here and look at what's inside and it's really really small so you have to bear with me all going to talk about his memory after today you will be experts in memory don't feel i came here on might not be able to ram remember anything but i know all about the memory of my computer which is the important amrit actually think about so the first thing in memory that we want to think about right when we talk about rent memory some people for the term like gramm for random access memory and so i can buy some new computer and you know i don't like to gigs of ram in my computer right this is what we're going to be talking about is what that really your computer actually means and how it relates to your java programs and why it's all important the very basic notion the very simplest concept of memory inside the computer something that's called the big and all the baby is it's actually shorthand for a binary digit savvy take binary digit squeeze it to get a real hard alter the extraneous letters pop out and you get bit and this is just a zero or anyone it is a single binary digit binary being based two numbers which means there is only zeros and ones as digits and that number system and that's that's imposed thinks it somewhere inside your computer there's actually a little piece of silicon or whatever hello transistor they can keep track of his ear or one so when you get we won't go below the transistor level to really interested that take like you know and e-class but the debt as a zero one and then we take a call when two bits and if they come together and something called the bite
