Hardware Questions

Floating gate avalanche injection MOS (FAMOS) transistor is used in each cell of EPROM.

The Quality Factor is also defined, as Q. So it is a number, which reflects the lossness of a circuit. higher the Q, the lower are the losses.

the quality factor is measurement of efficiency (or effectiveness) of a device or circuitry. In literal sense quality factor means qualitative performance of a device.

Flag is called as Low order rigister & Accumulator is called as High order Rigister.

In microprocessor more op-codes, few bit handling instrucitons. But in Microcontroller. fewer op-codes, more bit handling Instruction, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip.

the basic architectual difference is that microcontroller has an programmable memory while it is not the case with mivroprocessors.

An interrupt that can be turned off by the programmer is known as Maskable interrupt.

The address bus is unidirectional because the address information is always given by the micro processoe  to address a memory location of an input / output devices.

Byte contains 8 combinations of bits.

In 8086 Carry flag, Parity flag, Ausiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sing flag.
