Computer File Systems

Computers use files to store data and folders (directories) to organize those files into a logical structure.

A folder is a virtual container used to group and organize files and other folders within a computer's file system.

The cp command (copy) is used to duplicate a file or directory from a source to a destination.

The touch command is primarily used to update the timestamps of a file, but it also creates an empty file if the specified file does not already exist.

The file command examines a file to determine its type, such as whether it is a text file, an executable, or a directory. It looks at file headers rather than just the extension.

.MOV is a common multimedia container file format developed by Apple, primarily used for movies and video files.

Breadcrumbs are navigation aids that show the path of folders you have traversed to reach your current location. They help users understand the file hierarchy.

A podcast is a digital audio file made available on the internet for downloading to a computer or mobile device, typically available as a series.

ZIF stands for Zero Insertion Force, a type of IC socket that allows a chip to be inserted or removed without applying any force to the pins.

Zipping is the common term for compressing files to reduce their size. Other options like lacing, fastening, and buttoning are not standard technical terms for file compression.

FTP stands for File Transfer Protocol, a standard network protocol used for the transfer of computer files between a client and server on a computer network.

A system image is an exact copy of an entire drive partition, capturing all files, system settings, and the operating system. This serves as a structured alternative to manually copying individual files.

The file extension .pdf stands for Portable Document Format. Developed by Adobe in 1992, it is designed to present documents consistently across different operating systems, software, and hardware.

An MP3 file is a compressed digital audio format. It is widely used to store music, podcasts, and other sound recordings efficiently while maintaining high audio quality.

Both .jpeg (Joint Photographic Experts Group) and .png (Portable Network Graphics) are standard file formats used to compress, store, and display digital images and photographs on computers and the web.
