Difference between 32 bit and 64 bit operating system

         Difference between 32 bit and 64 bit operating system

I know among 70% of us have no clue what is the difference between a 32 bit and 64 bit operating system, we not even that which is better and what are its disadvantages and advantages. So lets see the main difference between the two and their reality.......

  First we must know what does the word 32 bit and 64 bit means, this by common sense we can infer that it refers to the space kind of something. very true, the bit(32 or 64) depends upon your processor. It is said that 64 bit is better and faster but a bit costlier, yes thats true, by bits refers to the width of the CPU’s register. More specifically, it means that CPU has some kind of buffer memory which is indeed very small(bits), this space is used for some very important data storage that needs to be processed even before the RAM comes into play, this register contains the set of commands on which the processor functions, this is were the "programing of processor" takes place and the commands are stored, hence greater the space, faster it would be for the processor to set the commends and even excess the data from RAM to the RAM, this indirectly results in limiting the amount of ram that we can install in our mother board. A CPU with a 32-bit register, for example, has a ceiling of 2³² addresses within the register and is thus limited to accessing 4GB of RAM.  Got the point? This is the reason as to why many times we are unable to install 6 or 8 gb ram even if our mother is compatible, The thing that need to be compatible is actually the processor and its registry. With the coming up of 64 bit processor and the operating system, it made us possible to install ram more than 192 gb of ram, this is the limit because you even need an operating system to work with ram, and till now windows 7 ultimate helps most with 192 gb supporting capability of ram, and rest or less (even professional supports the same). After having known this, lets see what are the advantages and disadvantages of 64 bit architecture operating system and processor(processor have no dram back, so only we will talk on operating system.

Advantages of 64 bit OS

        1. Highly boasted Efficiently It is very - very fast and smooth running, if the software is compatible, it will never hang-up in between, it is best for the ram hungry beasts like Virtual box, and games such as Crysis.

2
.      2. The Ram Best friend: Allows huge amount of support to rams, and can go up to 192gb depending up on the OS.

3.        

      3. High level of security: very high level ofprotection is offered including the hardware D.E.P., as well as Kernel Patch Protection that protects you against kernel exploits, and device drivers must be digitally signed which cuts down on the incident of driver-related infections.

 

Disadvantages of 64 bit OS

1.    
        1. Hardware Compatibility: It was seen a 3-4 years ago that the hardwares have great problem with this kind of OS as they were not compatible to it, and the update of the drivers were not helping. But today we always have to drivers given for different OS according our need.

2.      Software Compatibility: Many softwares specially the demos and light weight once did not match the compatibility, but many of them were made run by the help of new OS(ultimate), but still some problems still arrive that are unsolvable.

3.   

   2.Mother paradox: It is quite usually seen that not all the mother support 64 bit processor, so if even you want to upgrade to 64 bit, you will have to spend some fortune fro a new motherboard and processor.as now they generally come attached to each other and not separate.

At last I would like to conclude saying that thou 64 bit have certain driver and compatibility issues yet its advantages are enough to win over our hearts.
