for negative integers, the absolute value of the integer is equal to "the magnitude of the complement of the (n-1)-bit binary pattern plus
one

There are two representations of zero

There is only one representation for the number zero

beyond the range

below the range

Overflow happens if the carry in equal the carry out

A Single-Precision floating-point number occupies

A Double-Precision floating-point number occupies

Double Precision: mantissa ===> 1 bit + 23 bits

IEEE single-precision uses a bias of =127

Actual exponent is found by subtracting the bias from the stored exponent

0 11111111 00000000000000000000000

-1/0.0 : Zero

7-bit

8-bit Latin is a superset of ASCII

Unicode aims to provide a standard character encoding scheme, which is universal, efficient, uniform and unambiguous

Unicode encoding schemes

UCS-4 Uses 4 bytes (32 bits)

UTF-8 is a....... -length

variable width character encoding capable of encoding all 1,112,064 valid code points in Unicode
using one to four bytes

Same as UCS-4, which uses 4 bytes for each character – unencoded
