Document Summary
4 main computing functions - apipos = accept input, process input, process output, Cpu - central processing unit, handles all of the processing, rated by number of cores. Control unit - component of cpu that coordinates most of the actions of the computer. Alu - arithmetic logic unit; component of processor that performs arithmetic, comparison, and other operations. Registers - small high-speed data locations that temporarily hold data and instructions. Transistors - an electronic switch that opens or closes the current. Ram - random access memory; temporary storage for instructions that is wiped when the computer turns off. Usb-c (usb 3. 1) and usb 3. 0 - usb-c is much faster than its predecessor, usb 3. 0. Decimal vs. binary: decimal is base 10, binary is base 2. Storage capacities - kb, mb, gb, tb. Binary arithmetic - 256 128 64 32 16 8 4 2 1, add numbers to get to the number you want, then drop the leading zeroes.
