32-bit

From Free net encyclopedia

Template:N-bit 32-bit is also a term given to a generation of computers in which 32-bit processors were the norm.

The range of integer values that can be stored in 32 bits is 0 through 4294967295, or −2147483648 through 2147483647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory.

The external address and data buses are often wider than 32 bits but both of these are stored and manipulated internally in the processor as 32-bit quantities. For example, the Pentium Pro processor is a 32-bit machine, but the external address bus is 36 bits wide, and the external data bus is 64 bits wide.

Images

In images, 32-bit refers to 24-bit truecolor images with an 8-bit alpha channel.
