• Answer PointersAll information inside a computer is represented in the form of bits (binary digits) that have the values 0 or 1. The basic unit of information accessed in a computer (e.g., in a store or load operation) is the word which varies from 8 bits for simple microcomputers to 64 bits (or more) for high-performance computers.
• There is no intrinsic (or inherent) meaning in a string of bits. A string of bits means only what the programmer or computer designer intended. All data in a computer has to be interpreted in the way it was intended (e.g., as a number, an instruction, text, video, image, sound…).However, certain standards have been universally agreed upon to represent information – particularly in the field of number and character representation.
• A string of bits; for example, 01001010 can be regarded as an unsigned binary value with the 1s having the values (weights) 20, 21, 22, 23,… In this case, 01001010 represents 27 + 23 + 21 = 128 + 8 + 2 = 138. This form of representing numbers is the default mechanism used by many computers.
• An unsigned integer with n bits must fall within the range 0 to 2n-1 (inclusive). For 8 bits this is 0 to 255. An error will occur if the possible range of numbers is exceeded. For example, in 8 bits 11111111 + 1 represents 255 + 1 but the results in 8 bits is(upper 32 bits and lower 32 bits).

For example, in 8 bits 11111111 + 1 represents 255 + 1 but the results in 8 bits is 00000000 because the correct answer 256 cannot be represented in 8 bits. You can create longer integers by chaining numbers together; for example, a 32-bit machine can create 64-bit integers by concatenating two consecutive 32-bit integers (upper 32 bits and lower 32 bits).
