In what form do the hexadecimal numbers need to be converted for a computer’s digital circuit to process them?

1 answer:

5 0

Hexadecimal numbers are just a convenient representation of binary data. When entered as text, they consist of ASCII characters 0-9 and a-f. The numbers will then have to be converted to binary. This is accomplished by converting to uppercase, subtracting the ASCII offset (48 for 0-9 or 55 for A-F), so that the result is a number between 0 and 15 (inclusive). This can be stored in computer memory to represent 4 bits.

Hexadecimal numbers represent binary numbers in the following way:

hex | binary

0 = 0000

1 = 0001

2 = 0010

3 = 0011

4 = 0100

5 = 0101

6 = 0110

7 = 0111

8 = 1000

9 = 1001

a = 1010

b = 1011

c = 1100

d = 1101

e = 1110

f = 1111

As you can see, no other 4 bit combination exists.

Convert the following four unsigned binary numbers to decimal and show your work:

Ber [7]

Answer:

23 ,21,10,63,13

Explanation:

We have to convert binary to decimal

10111 corresponding decimal number is

$1\times 2^4+0\times 2^3+1\times 2^2+1\times 2^1+1\times 2^0=23$

10101 corresponding decimal number is

$1\times 2^4+0\times 2^3+1\times 2^2+0\times 2^1+1\times 2^0==21$

01010 corresponding decimal number is

$0\times 2^4+1\times 2^3+0\times 2^2+1\times 2^1+0\times 2^0=10$

111111 corresponding decimal number is

$1\times 2^5+1\times 2^4+1\times 2^3+1\times 2^2+1\times 2^1+1\times 2^0=63$

001111 corresponding decimal number is

$0\times 2^5+0\times 2^4+1\times 2^3+1\times 2^2+1\times 2^1+1\times 2^0=13$

What is the output of the following code?

Lynna [10]

Answer:

The output is 24

Explanation:

Given

The above code segment

Required

The output

We have (on the first line):

$x = 6$

$y = 3$

$z=24$

$result=0$

On the second line:

$result = 2*((z/(x-y))\%y+10)$

Substitute the value of each variable

$result = 2*((24/(6-3))\%3+10)$

Solve the inner brackets

$result = 2*((24/3)\%3+10)$

$result = 2*(8\%3+10)$

8%3 implies that, the remainder when 8 is divided by 3.

The remainder is 2

So:

$result = 2*(2+10)$

$result = 2*12$

$result = 24$

<em>Hence, the output is 24</em>

_____ assures the interface will act as the users expect, while _____ assures it will look pleasing. Select one:

Agata [3.3K]

Answer:

C. consistency, aesthetics

Explanation:

Based on the descriptions given to us in the question we can deduce that the answer is C. consistency, aesthetics. This is because "consistency" is defined as something that always delivers the same results, which is what users need from the interface in order to understand it and continue using it. While "aesthetics" is defined as the visual representation of something (how something will look).
