64 bit - What is the difference between 64-bit and 32-bit Operating systems?






I know that there are 2 types of OSs, 64 bit and 32 bit What is the main differences between them?


And if I am buying a new laptop, which one should i install?


It will be able to run all applications if I installed either of them?


I am talking mainly about windows Operating systems, but you can answer about others as well.


Answer



mainly the amount of RAM accessible. In most 32bit OSs there is a 4gb (closer to 3gb actually) ceiling. I believe vista x64 can access up to 128gb.


Realistically, unless you're a power user it won't matter. Very few activities you'd do on a daily basis will require more than 3gb of memory. Also, driver support for 32bit OSs is slightly better.


64bit apps will not run in a 32bit environment. However, you probably won't find very many apps that are exclusively 64bit. 32bit apps will run fine 99% of the time in x64.
