A byte is usually equal to 8 bits. C C - Celsius - A temperature measurement system where 0° is the freezing point and 100° is the boiling point of water. cache - A special high-speed storage mechanism which can be either a reserved section of main memory or an independent high-speed storage device. The cache enhances the efficiency of many microprocessor operations. L1 cache - Primary cache stored inside the microprocessor.
