The beauty of modular architecture is that you can replace or add any one component (module) without affecting the rest of the system. The opposite of a modular architecture is an integrated architecture, in which no clear divisions exist […]

Where the word modular represents in sections or designed for easy change and expansion, the term modular computer refers to a multiprocessing computer system where processing, memory, and peripheral units can be added or removed without disrupting its operation.
- modulate
To blend data into a carrier signal. At the receiving side, a device demodulates the signals by separating the constant carrier signals from the variable data signals. For example, radio uses two types of modulation – amplitude modulation (AM) and frequency modulation (FM) – to mix audio signals with an AM or FM carrier signal. […]
- modulation fallback
When signals are transmitted from one modem to another, each modem interfaces at a specific speed. If one modem communicates at a faster rate than the modem at the other end, then the faster modem falls back to a slower modulation. For example, if a user connects to the Internet using a 14000-bps modem and […]
