• speed (in Mega Hertz (MHz), Giga Hertz (GHz))
• amount of memory (Cache in Bytes)
CPUs use enormous amounts of electrical power relative to their size, which in turns requires that they be cooled by large fans or liquid cooling system. The fans are the source of noise when the computer is turned on - the operation of the chips is silent.
Процессоры потребляют огромные объемы электроэнергии относительно их размера, что в свою очередь требует, чтобы они были охлаждается большими вентиляторами или системой жидкостного охлаждения. Вентиляторы являются источником шума при включении компьютера - работа чипов молчит.

Содержание слайда: Data presentation in computer systems
The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0 or 1.
The byte is a unit of digital information that most commonly consists of eight bits.
1 Bit = 0 or 1
1 byte = 8 bits
