Assignment is due in on Thursday 18th October 2001
Binary Arithmetic
1. Convert the following numbers to binary using twos complement representation
9 -6 -99
2. Assuming 10 bits represent a binary number, with the first being a sign bit (twos
complement). Convert the following binary digits to decimal
000011101
001001011
110001111
3. Normalise the following numbers, which are held with a 10-bit mantissa and
6-bit exponent
0 000000110 000111
0 000010111 000110
1 111110111 000000
1 111111010 000011
4. the binary number 1010 1011 0111 can be represented in a number of different
ways
a. State its hexadecimal form
b. State its value in denary if it represents
(i) an unsigned binary digit
(ii) a twos complement floating point number with an eight bit mantissa
followed by a 4-bit exponent

1) What is an operating system?
the operating system is the set of basic programs and utilities that make your computer run. It is what the user interacts with to perform all the tasks. Examples are windows or UNIX
3) What is
> multiprogramming?
Where the processor performs more than one task at a time, it's quite similar to parallel processing.
5)
> Describe each of the following processing modes
a) Batch
Everything is processed one after the other. Its like a conver belf full off stuff where only one item can be delt with at the one time.
6) What is a network
> operating system?
An operating system which is used to control what happens on the network.
9) What is a pathname?
It is like an address of where a file or folder is
ie
C:Myfolder/file1.doc
