Hi mamtaji,
        The cache is defined as a smaller, faster memory which stores copies 
of the data from the most frequently used main memory which  is called RAM. 
In other words  In other words it is used  to reduce the average time to 
access main Memory.
    When the processor wishes to read or write a location in main memory, it 
first checks whether that memory location is in the cache.
     If the processor finds that the memory location is in the cache,  the 
processor immediately reads or writes the data in the cache.
    In short a computer without cache means very slow computer even though 
RAM is present, it is considered slow as compared to those machines which 
have cache. I hope it helped to know the concept of Cache.
