Ever since the first computer was built, each new computer
has been smaller, faster, and more powerfully. Most modern           
desktop computer can perform operations that only                        
supercomputers could do in past. The trend will no doubt                
continuing, but just how small and fast can computers get?               
Will we get computers that is so small that they “disappear”         
which is, will they become so small that we will wear them             
inside their body? I think it’s possible that future PCs will               
be made of anything other than plastic and glass. The                      
computer will no longer be a thing in your house, but                    
instead of something very small that you can bring                         
with you wherever you go.
