Data Representation: แบบฝึกหัด

Which of the following represents the denary value 43 in 8-bit binary?

A specialized digital sensor uses a 6-bit two's complement system to represent temperature readings. What is the denary value of the largest positive integer that can be represented in this system?

Consider an 8-bit two's complement system. What is the result of the binary addition \(01011010 + 11010011\) in denary?

What is the denary equivalent of the 8-bit unsigned binary number 01011010?

Perform the binary addition: \(01101100 + 00111010\). What is the result in denary?

State the hexadecimal representation of the denary number 255 and explain how you arrived at the answer.

Identify the 8-bit two's complement binary representation for the denary value \(-128\). Justify your answer briefly.

A digital system uses 8-bit two's complement. If the binary value is \(1000\,0101_2\), determine its denary value by showing the weight assigned to the Most Significant Bit (MSB).

Explain how computers use 8-bit extended ASCII to represent the English word "CODE". Your explanation should include:
(a) The process of how each character is stored as a bit pattern.
(b) Why 8 bits are sufficient for the extended ASCII character set compared to standard ASCII.

Binary representation of signed and unsigned integers is essential for computer processing.
