A programming language acts as a translator between you and the computer. Rather than learning the computer's native language (known as machine language), you can use a programming language to instruct the computer in a way that is easier to learn and understand.

It's a compact way of doing an if-else statement.

General Format is

<<em>condition</em>> ? <if condition is true> : <else>;

Suppose that a 64MB system memory is built from 64 1MB RAM chips. How many address lines are needed to select one of the memory

alexdok [17]

Answer:

6 address lines

Explanation:

The computation of the number of address lines needed is shown below:

Given that

Total memory = 64MB

= $2^6MB$

= $2^{26} bytes$

Also we know that in 1MB RAM the number of chips is 6

So, the number of address lines is $2^{26} address$ i..e 26 address lines

And, the size of one chip is equivalent to 1 MB i.e. $2^{20} bytes$

For a single 1MB chips of RAM, the number of address lines is

$\frac{2^{26}}{2^{20}} \\\\= 2^6 address$

Therefore 6 address lines needed
