1 Your PC's Performance Features Benefits of 32-bit Applications Benefits of 32-bit Applications Your HP Vectra PC has been designed to offer optimized performance. The benefit that you can gain from your PC's advanced features will be determined by the software that you use. NOTE The advanced Pentium Pro processor installed in your PC provides the best performance when used with 32-bit operating systems and applications. Applications and the Processor Any application you run on your PC 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. 32-bit Applications 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. 16-bit Applications Many of today's more popular applications, including any designed for Windows for Workgroups, are 16-bit applications. These use 16-bit instructions, and handle both data and memory addresses as 16-bit quantities. English 21

Your PC’s Performance Features
Benefits of 32-bit Applications
Benefits of 32-bit Applications
Your HP Vectra PC has been designed to offer optimized performance.
The benefit that you can gain from your PC’s advanced features will be
determined by the software that you use.
NOTE
The advanced Pentium Pro processor installed in your PC provides the
best performance when used with 32-bit operating systems and
applications.
Applications and the
Processor
Any application you run on your PC 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.
32-bit Applications
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.
16-bit Applications
Many of today’s more popular applications, including any designed for
Windows for Workgroups, are 16-bit applications. These use 16-bit
instructions, and handle both data and memory addresses as 16-bit
quantities.
