RTC stands for Real Time Clock. The DS1302 RTC Chip is referred to as the Real Time Clock or a TimeKeeping Chip. THe DS1302 RTC Chip has a built in Trickle-Charger.
CMOS Chip
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.
A clock cycle is the low-hi-low transition of the clock. On each transition, the processor executes an instruction. It determines the speed if execution. So the faster the clock runs, the faster the chip works. This is why a Pentium 1 GHz chip is a LOT faster than a Pentium 100 MHz chip. Its unit is in Hz (or s-1) because it is a factor of frequency...
To keep the clock chip running even when the power is off.
The 555 is not a sound chip, it is a general purpose programmable timer. As such, it is possible to program it to generate sounds or clock digital sound synthesizer chips.

This is the the thing for micro controller . Normally in microcontroller operation we used to give the clock pulse to connected circut chips .One chip requires 4 clock pulse .then the second, third vise versa . By which the pulse starts from 4 is for first chip, 8 is for second chip(4+4), 16(4+8+4) is for thir.............Like that depending upon the requirement of the clock signal for chips we used to tell 16 bit counter , 32 bit counter ect.
A computer's clock signal is typically generated using oscillating crystals. The resulting clock signal is sometimes multiplied to higher frequencies or divided to lower ones, as needed by the hardware.Many computers also include a real time clock chip (RTC). This is permanently powered (using a small battery to continue running when the power is off). The RTC chip produces information about the current time of the day by counting seconds (or fractions of seconds). Those units are derived from a very reliable clock signal, typically derived from an oscillating crystal.
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 correct term is Dual Processor as in Intel Dual Processors. The chip is really only one chip but they process information twice for each clock cycle, so it fools the computer into thinking it is only one chip. Obviously since it can do twice as much processing it is a lot faster.
As fast as you can get it while staying within amd's vcore specifecation with the temperature under control. It's not high clock speed that will kill or reduce the life of the chip, it's higher vcore, because it causes electromigration in the chip, and higher heat which cased by the higher vcore and clock speeds.
