(a) |

6. |
(b) |
F -- files are created by the operating
system |
|
(c) |
F -- only the boot record is in ROM.
Actually, it can
boot any operating system
that it can find on disk. |
8. |
(c) | S (but it must be supported by graphics hardware) |
|
(d) | H (software-assisted modems are available, too) |
10. |
(b) |
T (however, if you refer to
"ASCII" characters as a
subset of Unicode, then
each "ASCII" character,
as all Unicode characters, is represented in
two bytes, with the first byte
equal to 0) |
12. |
Binary Decimal Hex
(d) 00001011 11 0B
(g) 00000101 10010010 1426 0592 |
14. |
|
512 * 512 * 8 bits = 256 KB. (It takes 8 bits to represent
256 = 28
different values.) |
16. |
|
Yes. You can use 2 bits per square, for example
00 = empty,
01 = 'o', 11 = 'x'.
Then you need
9 * 2 = 18 bits = 2.25 bytes. |
