If you are not using Android phone right at this moment, you may not have any idea about that or perhaps you have already used the phone borrowing it from some of your friends or may have seen it displayed it in the local cell phone store, but if you feel really tortured by any beguiling question about what Android OS actually is, I am going to tell you every information regarding this. Android OS is basically software through which you can configure a “virtual “Android phone running on the computer you are using absolutely free of cost. Just all you have to do is to install the free software and organize some setting for it. Make sure that you are installing Android software development kit (SDK).
But there are warning and limitations regarding the use of this software. You cannot use it for making calls .This software will give you an opportunity to discover some Android application without buying anything. There are other limitations too. You will be pretty dismayed to hear that you won’t be getting any location services which make you conscious about your current physical location. It is of course possible for your virtual Android device to work with a camera or GPS attached to it but implementing this procedure with some modification in developer level is not too easy to comprehend. You may be noticing that your virtual Android device will run slow unlike its ‘real counterpart. With the installation of Android device on your pc, you need to be very careful about your system security especially when you already entered some personal information to it such as goggle account credentials. You may be intrigued to know if the software application is basically a malware in disguise or not. To retain the security system on your pc, you need to install some mobile security software.

Programs designed to run on 64 bit OS will not work on 32 bit OS version but the programs designed for 32 bit (apart from certain antivirus) OS will certainly work on a 64 bit system. Same applies to the device drivers as well. The 32 bit OS only addresses up to 4GB memory, which is total of RAM and memory which is reserved for the hardware. All the hardware parts of our computer have some onboard memory and the motherboard needs to reserve the space for mapping this memory. Since the total of physical & reserved memory can not exceed the limit set by the OS, you can use the full available physical memory. it does not matter here how much of memory needs to be installed as you can not use more physical memory without changing the hardware with the one requiring less onboard/reserved memory or by shifting to a 64 bit operating system and it does not matter whether you have 4GB or 8GB of memory, you will always be limited to 4 GB only unless you decrease the reserved memory. For more information on the hardware components having less onboard memory or which processor supports 64 bit OS for an optimum performance using higher memory and any other support contact our
