How many megahertz does a megabit use?

Answer 1

None. The two are quite different measures, describing quite different things. An oscillation is something that goes up and down, back and forth, in and out. It starts in one place, goes to another, goes back to the first, then to the second, and so on. Examples are a pendulum, a child on a swing, or a piston in an engine. The rate at which this happens was once measured in cycles per second (c/s), which is self descriptive. This unit has now been renamed the Herz, or Hz. One of these is one cycle per second. A megahertz (1MHz) is one million Hz. A byte is a no. of bits that are treated as a unit, and stored as a unit. How many bits in a byte is arguable - from the earliest days of computers each designer could decide for himself how many bits to a byte in his machine, provided he told the programmers. At least one computer in the middle 60s had six bit and eight bit bytes in the same machine simultaneously ! All PCs in use today use eight bit bytes throughout. The size of Memory, aka RAM, is expressed in kilobytes, megabytes or gigabytes. A one megabyte memory holds just over one million bytes.

Answer 2

A megabit does not use megahertz directly, as they measure different things. A megabit refers to the amount of data transmitted, while megahertz measures the frequency of a signal. In digital communications, the data rate (e.g., megabits per second) is more relevant than the frequency.
