The processing speed depends on DATA BUS WIDTH

8-bit Processor - 8085 / Z80 / 6800
16-bit Processor - 8086 / 68000 / Z8000
32-bit Processor - 80386 / 80486

First of all cache memory is very fast memory that the 
processor can access much more quickly than main memory or 
RAM. Currently processors can operate at speeds much 
greater than affordable, reliable memory can supply the 
necessary data.Cache memory, is much like other memory, 
except it can operate much faster, and much more expensive.

Cache Memory:-A relatively small section of very fast memory
(often called static RAM) reserved for the temporary 
storage of the data or instructions likely to be needed 
next by the processor.Also improves the speed of CPU.

Increased speed and memory capacity of microprocessors 
together with the support fir virtual memory and  Growth of 
client server computing

The repeated execution of a loop of code while waiting for 
an event to occur is called busy-waiting. The CPU is not 
engaged in any real productive activity during this period, 
and the process does not progress toward completion.

When the process hangs, we can tryout setting priority to 
HIGH for the perticular process from Task Manager. If still 
it doesn't come over, we need to kill that process 
depending on cruciallity of that process

Two programmer(Threads) at a Same Time is call syncronous 
and Two Prorammer At differnt time is call Asynchronous.....
example:: audio and Vedio at Same time is syncronous 
audio and Vedio is differnt time is Asynchronous

table consisting of interrupts.

THIS IS A TABLE CONTAINING VALUES OF ADDRESSES OF PROGRAMS 
THAT HANDLE INTERUPTS AND HAS 256 4 BYTE ADDRESS

Intarrupt is Table  
all Data and  programmer waiting for the Processing is 
Micro Processer Hence the Chech memory which will Make a 
List of Data or Prommer which is Interrupt table......

Every interrupt is assigned a number.
and an interrupt table contains mapping of those numbers to 
corresponding handler function pointers . :)
