Document Summary
The instructions that make up your program and the data it acts upon have to be instantly accessible while executing the program. This is stored in the random access memory(ram). Ram is volatile memory, if the power of the pc is lost the ram is lost. Anything that must be saved has to be written to the disks. Ram can be thought of as an ordered sequence of boxes, representing 1 when full and 0 when empty. The computer uses these to think in terms of true and false, 1 is true and 0 s false. Each of these boxes are called a bit, the contraction of a binary digit. Bits in memory are in groups of eight called a byte. They are labeled with a unique number, the first one starting a 0 and counting upwards. The labels are called memory addresses, and are the references of the byte.
