A hard disk, also known as a hard disk drive (HDD), is a data storage device that uses magnetic storage to store and retrieve digital information. Hard disks are commonly used in computers, servers, and other electronic devices for long-term data storage. Here are the key features and characteristics of hard disks: Key Features of Hard Disks Magnetic Storage: Hard disks use magnetic material on rotating platters to store data. Data is written to and read from the platters using re...

NFS Definition NFS (Network File System) is a distributed file system protocol developed by Sun Microsystems in the 1980s that allows users to access files over a network as if they were on their local storage. NFS enables seamless sharing of files and directories across different machines, regardless of the operating system, making it a widely used solution for networked environments. Key Features of NFS Architecture: NFS operates on a client-server architecture, where a server ...

A character refers to any individual unit of text that can be typed or displayed on a computer. This includes a wide variety of elements, such as: Types of Characters Letters: Uppercase (A, B, C, ...) and lowercase (a, b, c, ...) letters from the alphabet. Numbers: Digits from 0 to 9.

Filename Definition A filename is a text string that identifies a file. Every file stored on a computer's hard disk has a filename that helps identify the file within a given folder. Therefore, each file within a specific folder must have a different filename, while files in different folders can have the same name. Filenames may contain letters, numbers, and other characters. Depending on the operating system, certain characters cannot be used since they conflict with operators or other...

Syntax refers to the set of rules and principles that govern the structure of sentences in a language, including programming languages. It dictates how symbols, words, and phrases can be combined to create valid expressions and statements. Here are the key aspects of syntax: Key Aspects of Syntax Rules of Structure: Syntax defines how components of a language (such as keywords, operators, and punctuation) are arranged to create valid statements or commands.

A subdirectory is a directory (or folder) that exists within another directory in a file system hierarchy. Subdirectories help organize files and other directories into a structured format, allowing for better management and navigation of data. Here are the key aspects of subdirectories: Key Features of Subdirectories Hierarchical Structure: Subdirectories are part of a tree-like structure in a file system. Each directory can contain files and additional subdirectories, creating a...

Path Definition In the real world, paths are trails or streets than lead to a certain location. Similarly, in the computer world, a path defines the location of a file or folder in a computer's file system. Paths are also called "directory paths" because they often include one or more directories that describe the path to the file or folder. A path can either be relative or absolute. A relative path defines a location that is relative to the current directory or folder. For example, the ...
