Benefits of 32-bit Applications

Your HP Vectra XW has been designed to offer optimized performance.

The benefit that you can gain from your Personal Workstation's

features will be determined by the software that you use.

The Pentium Pro processor installed in your system provides the best

performance when used with Windows NT and 32-bit applications.

Any application you run on your Personal Workstation presents itself to

you as a single unified object. But to the processor an application

consists of many single instructions, each of which controls some small

part of the overall function of the application.

Each instruction is applied to source data from memory to produce

new (result) data. When executing an instruction, the processor loads

the source data and its associated memory address (location) into a

temporary storage area called a register. The new data produced and

its corresponding address are also stored in registers.

For 32-bit applications all of these quantities are 32-bits in length; the

instructions are 32-bits long and act on 32-bit data items which have

corresponding 32-bit memory addresses.

Many older applications are 16-bit applications. These use 16-bit

instructions, and handle both data and memory addresses as 16-bit

quantities.
