The 8086/8088 has a clock oscillator circuit. You provide a crystal, and it will generate a clock signal that controls the speed of the processor. In that respect, it has a clock.
The 8086/8088, however, does not have a time of day or date clock. You can build a software entity that keeps day/date time using interrupts from a divider off of the clock oscillator but, that is not the same thing as a non-volatile clock chip such as provided in the PC, but which is not part of the 8086/8088.
The 8086 Microprocessor operate to require frequency that is provided by clock generator to 8086 Microprocessor and also Synchronization various component of 8086.
that depends on the microcontroller. check the datasheet.
One clock cycle, repeated until READY is true.
No the system clock is built into the motherboard.
That depends somewhat on the type of clock and when it was built.
it was built in 1088 A.D
The astronomical clock was first installed in 1410.
Early microprocessor neded clock input to be given externally, i.e. an extra clock generator chip is necessary. the clock generator chip had two pins between which a crstal or an RC circuit could be connected for the generation of basic frequency desired. however, microprocessor, that were designed after 1978(Intel 8085, M6809, etc.) had the clock generator circuit embedded in the microprocesor chip.
The Nintendo DSi does indeed have a built in alarm clock. It is accessible from the System Settings Icon
The number of instructions that can execute in one second in the 8086 microprocessor is highly dependent on clock speed, memory wait time, and instruction complexity mix, but the generally accepted performance factor is 0.33 MIPS (Million Instuctions per Second) at a clock speed of 4.77 MHz.

To increase the speed of the 8086, you need to increase the clock speed, reduce the number of wait states, or both. You could also optimize your code so that it runs faster. Since the 8086 is a segmented memory architecture, it is more efficient to use operands in one segment and to make near references to them.
