Answer:

Memory of the system is 2^{23} .

Explanation:

Computer programs are usually written in Byte. That is to say we expressing our megabyte in byte.

NOTE :  1 Megabyte  (MB)  = 2^{20} in Byte

Mathematically written as  :   1 MB=2^{20}

                                                16 MB=X

Cross multiplying the above to make X the subject of the formula.

                X = \frac{16 x 2^{20} }{1}  ………………i

Converting 16 to factor of two

We having  = 16 = 2^{4}  

Therefore equation I becomes =  x =  \frac{2^{4} x 2^{20}  }{1}

          Applying multiplication law of indices

               X =  =2^{4} + 2^{20} =2^{24}  ……………………………..ii

To convert  equation ii to the number of words we divide by 2

Therefore number of words :  \frac{2^{24} }{2}

applying the law of indices x^{a} ÷ x^{b}  = x^{a-b}

Number of words is equal to =2^{24-1} = 2^{23}

Thank you.

There widely used bus standards are:

  • PCI (Peripheral Component Interconnect)
  • SCSI (Small Computer System Interface), and
  • USB (Universal Serial Bus).
  • ISA (Industry Standard Architecture)
