Document Summary
4:28 pm: a digital computer can be viewed as a set of interacting components, the components act together to make the computer work. The cpu gets its next instruction from memory. It"s an instruction to read in a value from memory. The cpu then reads in the next instruction: that instruction tells it to read in another value from memory. It"s an instruction to add the two numbers, and store the value in another location on the processor. It says to store the value we just calculated in memory. Cpu and ram are connected via the bus to communicate. Gb= billion: memory is organized into locations, these locations have numerical addresses, an instruction or data value is found in memory by giving its address. Just as cpus execute millions of instructions per second, memories hold millions or billions of values: the capacity of a memory is measured by a slightly convoluted system.
