System clock rate = rate of an electronic pulse used to synchronize processing
(Only one action can take place between pulses.)
Measured in megahertz (MHz) where 1 MHz = 1 million cycles per second or gigahertz (GHz) where 1 GHz = 1 billion cycles per second.
This is what they are talking about if they say a computer is a 2.4 GHz machine. It's clock rate is 2.4 billion cycles per second.
Bigger number = faster processing
so, the faster the system clock is the more instructions you can perform
The crystal frquency in an 8085 system is twice the desired clock frequency, so a crystal of 2.2 MHz is required to operate at 1.1 MHz.Note: Clock frequency is not the same as instructions per second, because the instructions in an 8085 take a variable number of clock cycles, between 4 and 18, to execute.

The pace of the system clock, called the clock speed, is measured by the number of ticks per second. The faster the clock speed, the more instruction the processor can execute per second.

With pipelining, the CPU begins executing a second instruction before the first instruction is completed. Pipelining results in faster processing because the CPU does not have to wait for one instruction to complete the machine cycle. The system clock is a small chip that the control unit relies on to synchronize computer operations. The faster the clock, the more instructions the CPU can execute per second. The speed at which a processor executes instructions is called clock speed. Clock speed is measured in megahertz (MHz), which equates to one million ticks of the system clock.
in computers speed refers to the number of instructions acomputer can execute at every clock pulse
Bus Clock is based on the System Clock. In other terms Bus Clock is derived from system Clock. Bus Clock is usually half System Clock. (Busy Clock = System Clock / 2)
The number of clock cycles per minute which determines the spped of le system
If this is a homework assignment, you really should try to answer it on your own first, otherwise the value of the reinforcement of the lesson due to actually doing the assignment will be lost on you.The number of clock cycles per instruction in the 8085 varies between 4 and 18, so the number of instructions per clock cycle varies between 0.25 and 0.056. This does not include wait states.
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
Most systems obtain their time and date by reading from the Real Time Clock (RTC) at bootup, and then auto-incrementing the system clock after that. To change the system clock in a Unix or Linux system, issue a command like:date -s "1 JAN 1970 00:00:00"where the date is January 1, 1970, at 12:00 midnight.
