In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes (640 × 1024 bytes) of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs.
The operating system creates _____ from the physical computer
Safe mode is a diagnostic mode of a computer operating system (OS). It can also refer to a mode of operation by application software. In Windows, safe mode only allows essential system programs and services to start up at boot. Safe mode is intended to help fix most, if not all problems within an operating system. It is also widely used for removing rogue security software.

In safe mode, an operating system has reduced functionality, but the task of isolating problems is easier since many non-core components are disabled, such as sound, and many core components are enabled, such as keyboard drivers, mouse drivers, vga drivers, etc. An installation that will only boot into safe mode typically has a major problem, such as disk corruption or the installation of poorly-configured software that prevents the operating system from successfully booting into its normal operating mode.
Safe mode typically provides access to utility and diagnostic programs so a user can troubleshoot what is preventing the operating system from working normally. Safe mode is intended for maintenance, not functionality, and it provides minimal access to features.
A ....... is a named location on a disk where files are stored
When talking about file systems, a folder (also called directory, or catalog) is a way to organize computer files. A folder is a storage space that many files can be placed into to group them together and organize the computer. A folder can also contain other folders.
Which type of command requires additional files to perform specific operations?
External commands are predefined commands for end users. They are operating-system independent and are protected by authorizations, so that normal end users can schedule only those commands that the system administrator permits them to.
The operating system (OS) is the best-known example of system software. The OS manages all the other programs in a computer. According to some definitions, system software also includes system utilities, such as the disk defragmenter and System Restore, and development tools such as compilers and debuggers.
A user-interface that is easy to use is considered to be
A GUI is considered to be more user-friendly than a text-based command-line interface, such as MS-DOS, or the shell of Unix-like operating systems. Unlike a command-line operating system or CUI, like UNIX or MS-DOS, GUI operating systems are easier to learn and use because commands do not need to be memorized.
A ..... is a flash memory storage device that plugins into a USB port
A USB flash drive is a device used for data storage that includes a flash memory and an integrated Universal Serial Bus (USB) interface. Most USB flash drives are removable and rewritable. Physically, they are small, durable and reliable.
