1. Floppy disks are inexpensive and reusable. 2. If a printer malfunctions, you should check the interface сable. 3. The multiplexor was not working because someone had disconnected it by mistake. 4.

Your pay rise is retroactive to the beginning of June and you will receive a biannual bonus. 9. The octal1 and hexadecimal2 systems are number systems used as a form of shorthand in reading groups of four binary digits. 10. As the results are irregular, the program will have to be rewritten.
NB: 1octal - A numbering system that uses eight digits. It is used as a shorthand method for representing binary characters that use six-bits. Each three bits (half a character) is converted into a single octal digit. Okta is Greek for 8. 2hex - (HEXadecimal) Hexadecimal means 16. Computing of a system of numerical notation that has 16 (the figures 0 to 9 and the letters A to F) rather than 10 as a base which is used as a shorthand for representing binary numbers. Each half byte (four bits) is assigned a hex (octal) digit as follows:
| Dec
| Binary
| Octal
| Hex
| Dec
| Binary
| Hex
A
B
C
D
E
F
|
In a hex number, each digit position has a value 16 times greater than the one to its right. Two hex digits make up one byte; for example, A7h (h means hex) is equivalent to decimal 167 (10x16 + 7x1).
