Please answer the following question: Information: - Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined (multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). - Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. This includes all versions of Windows 95 and Windows 98. Windows ME is sometimes included. - Windows Millennium Edition, or Windows ME (marketed with the pronunciation of the pronoun "me", but commonly pronounced as an initialism, "M-E"), is a graphical operating system from Microsoft released to manufacturing in June 2000, and launched in September 2000. It was the last operating system released in the Windows 9x series. - Multi-user software is software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete. However, the term "multitasking" is more common in this context. - Scramdisk is a free On - the - fly encryption program for Windows 95 , Windows 98 , and Windows Me . A non-free version was also available for Windows NT. The original Scramdisk is no longer maintained ; its author , Shaun Hollingworth , joined Paul Le Roux ( the author of E4M ) to produce Scramdisk 's commercial successor , DriveCrypt . The author of Scramdisk provided a driver for Windows 9x , and the author of E4M provided a driver for Windows NT , enabling cross-platform versions of both programs . Although Scramdisk 's source code is still available , it was only released and licensed for private study and not for further development . There is a new project called ScramDisk 4 Linux which provides access to Scramdisk and TrueCrypt containers . Older versions of TrueCrypt included support for ScramDisk . - Disk encryption software is computer security software that protects the confidentiality of data stored on computer media (e.g., a hard disk, floppy disk, or USB device) by using disk encryption. - An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function. - Windows 95 (codenamed Chicago) is a consumer-oriented operating system developed by Microsoft. It was released on August 24, 1995, and was a significant improvement over the company's previous DOS-based Windows products. - Microsoft Corporation (commonly referred to as Microsoft or MS) is an American multinational technology company headquartered in Redmond, Washington, that develops, manufactures, licenses, supports and sells computer software, consumer electronics and personal computers and services. Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office office suite, and Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface tablet lineup. As of 2016, it was the world's largest software maker by revenue, and one of the world's most valuable companies. - On-the-fly encryption (OTFE), also known as real-time encryption and transparent encryption, is a method used by some disk encryption software. "On-the-fly" refers to the fact that data is automatically encrypted or decrypted as it is loaded or saved. It is often used when the storage medium is portable or could be stolen, so that the data on the storage medium needs to be encrypted at all times. - In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can access it. Encryption does not of itself prevent interference, but denies the intelligible content to a would-be interceptor. In an encryption scheme, the intended information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, large computational resources and skill are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. - Windows 98 (codenamed Memphis while in development) is a graphical operating system by Microsoft. It is the second major release in the Windows 9x line of operating systems and the successor to Windows 95. It was released to manufacturing on May 15, 1998 and to retail on June 25, 1998. - Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It is a processor-independent, multiprocessing, multi-user operating system. What is the relationship between 'scramdisk' and 'disk encryption software'?
