32-bit VS 64-bit / Difference between 34-bit and 64-bit

32-bit VS 64-bit / Difference between 34-bit and 64-bit

Computer memory has units and each unit has specific amount of storage in it. Most of the time operating systems are work on memory storage architecture called 32 bit or 64 bit. Versus zone is going to explain the difference between 32 bit and 64 bit. Following is the versus between 32 bit and 64 bit.

 

Number of bits:

64

Number of bits:

32

Architecture and Software Description:

64-bit architecture is based on registers, address or data buses 64 bits (8 octets) wide. For software, 64-bit means code use with 64-bit virtual memory addresses.

Architecture and Software Description:

32-bit architecture is based on registers, address or data buses 32 bits (4 octets) wide. For software, 32-bit typically means use of 32-bit linear address space.

Compatibility:

64-bit OS requires 64-bit CPU, and 64-bit applications need a 64-bit OS and CPU.

Compatibility:

32-bit operating systems (OS) and applications require 32-bit CPUs.

Systems Available:

XP Professional, Windows Vista, Windows 7, Windows 8, as well as Mac OS X and Linux.

Systems Available:

All editions of Windows 8, Windows 7, Windows Vista, and Windows XP, Linux.

Memory Limits:

64-bit systems allow up to 17 Billion GB of RAM.

Memory Limits:

32-bit systems are limited to 3.2 Gigabytes (GB) of RAM 32 bit Windows with address limitation do not attain to a full 4GB. It is hardware dependent, typically 3.25GB.

Pros:

• More RAM access • More efficiency • More virtual memory allocation • More security features.

Pros:

Fewer issues, more widely compatible

Cons:

• Possible driver compatibility • Some motherboard RAM limits • Legacy issues

Cons:

Less RAM access, less memory, less efficiency, fewer security features.
