In fiber optic transmissions, microbend is an imperfection in the optical fiber which was created during manufacturing. Microbending can cause extrinsic attenuation, a reduction of optical power in the glass. Unlike macrobending, the imperfection may not always be visible.
Contrast with macrobend.

(1) The lowest-level instructions that directly control a microprocessor. A single machine-language instruction typically translates into several microcode instructions. In modern PC microprocessors, the microcode is hardwired and can’t be modified. Some RISC designs go one step further by completely eliminating the microcode level so that machine instructions directly control the processor. At the other […]
The term microcomputer is generally synonymous with personal computer (PC), or a computer that depends on a microprocessor. Microcomputers are designed to be used by individuals, whether in the form of PCs, workstations or notebook computers. A microcomputer contains a central processing unit (CPU) on a microchip (the microprocessor), a memory system (typically read-only memory […]
A highly integrated chip that contains all the components comprising a controller. Typically this includes a CPU, RAM, some form of ROM, I/O ports, and timers. Unlike a general-purpose computer, which also includes all of these components, a microcontroller is designed for a very specific task — to control a particular system. As a result, […]
