The answer is D - A user-friendly computer program that allows the user to point and click on icons to make the computer function.
Answer:
4 Platters
Explanation:
The capacity of one platter
= 1024 x 2048 x 4096
<em>1 platter capacity= 8GB
</em>
For a 30GB hard disk, we need
30/8 = 3.75 platters.
<em>we round off the answer so 4 platters will be required.</em>
Answer
First part:
The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.
Second part:
The invalid bit sequence are option a. 01001000 and d. 11100111
Explanation:
Explanation for first part:
In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.
If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.
If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.
Explanation for second part:
A valid odd parity bit sequence will always have odd number of 1s.
Since in option a and d, total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.
And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.
Answer:
C. Binary can be used to represent more complex, higher level abstractions, including but not limited to numbers, characters, and colors. D. When data is large enough computers switch to using decimal representation instead of binary, because you can represent larger numbers with fewer digits
Explanation:
The answer to this question would be the last choice. The master program that controls the system hardware.
All computers require a software known as the <em>operating system</em> to properly function and allow you to use the computer. This operating system works as a "master program" that manages the computer's processes and memory.
