How is the sign of the number represented ?
The first number of the word is sign
The first bit of the word is reserved for the sign of the number.
The magnitude of the number
The last (least significant) bit.
Find the biggest among the following numbers. (127)8, (1101011)2, (A2B)16.
127
1101011
A2B
FF
Suppose 28 is a number in base 9 system. Convert this number to base 8 number
32
28
82
16
A 32 bit word would consists of
32 bytes
16 bytes
8 bytes
4 bytes
Normally, bytes are divided into two parts. How many bits are in each part?
4 and 4
4 and 2
4 and 6
2 and 4
The obvious reason for the usage of binary numbers instead of decimal numbers is
Ideal for coding purpose involving two state nature of components.
Easy to code
Processing is faster
Easy to use
2's complement of a number is obtained by
Changing all zeros to ones
By Adding one to its 1's complement
Decimal number conversion
None of these
The number system used almost universally humans is called
Binary
Octal
Decimal
Hexa
