What is an operating system ? Ans: An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for compute programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Q. What is the difference between 32-bit and 64-bit versions of operating system? Ans: The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system. 32 bit system has a limit of 4GB RAM to process data where as the 64 bit operating system has 2^64 bits of space to address and supports 16 hexabytes of RAM to process data.
What is File System ? In computing, a file system (or file system) is used to control how information is stored and retrieved. Without a file system, information placed in a storage area would be one large body of information with no way to tell where one piece of information stops and the next begins.
FAT32 Vs NTFS NTFS 1.Recovers Some disk related issues. 2.Support to larg disks 3.Better security Permission restrictions: We can provide read write and executable permission to files and folders. Encryption: By Which we can provide security to data encryption. FAT 32 1.Any user can read your files who has access to your machine. 2.You can not create partition larger than 32 GB and can not store file larger than 4 GB. 3.Does not have security in FAT32.
