Computer File Systems

.tar is an archive format that bundles files without compression. While often paired with compression (tar.gz, tar.bz2), .tar itself does not compress - it only archives. .rar and .z are actual compression formats.

When predefined reports are saved in Quality Center, they are saved as HTML files. This format allows the reports to be viewed in web browsers and shared easily while preserving formatting.

JIFF stands for JPEG Interchange Format File, which is a file format used for storing and exchanging JPEG-compressed images. Option A incorrectly uses 'Framed' instead of 'Format', while Option B changes 'JPEG' to 'Joint' and Option D changes 'Interchange' to 'Interactive'. JIFF files are essentially JPEG files with specific interchange formatting.

GIF stands for Graphics Interchange Format, a bitmap image format developed by CompuServe in 1987. It supports up to 8 bits per pixel and allows a single image to reference its own palette of up to 256 different colors. Options B and D incorrectly use 'Interactive' instead of 'Interchange', while Option C incorrectly uses 'General' instead of 'Graphics'.

EXE stands for executable, which refers to a file that contains a program that can be run by the operating system. These files contain machine code that the computer's processor can execute directly. Option A incorrectly uses 'extended', while Option C uses 'executive' and Option D uses 'explainatory' - neither of which are correct.

In Windows XP, simply hovering your mouse over a file icon displays a tooltip showing the file size and other details. This is the fastest method. Properties (A) requires multiple clicks, double-clicking opens the file, and the DOS command is slower.

The 2020 design software saves files in the .kit format, which is its proprietary file format for storing kitchen design projects. This format preserves all design elements, cabinet placements, and configuration data. The .dwg format is used for export, not primary saves.

The .doc extension is the traditional file format for Microsoft Word documents (versions 97-2003). This binary format was the standard for Word files before the introduction of the XML-based .docx format in Office 2007.

The .xls extension is the traditional file format for Microsoft Excel spreadsheets (versions 97-2003). This binary format was the standard for Excel files before the introduction of the XML-based .xlsx format in Office 2007. Not to be confused with .xlsx which is the modern format.

L&T named their alumni database 'The Ex-files' as a clever play on words - referring to former employees ('ex') and the popular paranormal TV show 'The X-Files'. The other options don't match L&T's actual naming convention.

WAV (Waveform Audio File Format) is a standard audio file format developed by Microsoft and IBM. It stores uncompressed audio data and is commonly used for high-quality audio on Windows systems. Image files use extensions like .JPG or .PNG, Winamp uses .M3U playlists, and video/movie files use .AVI or .MP4.

PSD is the proprietary file format for Adobe Photoshop, the industry-standard image editing software. It stands for 'Photoshop Document' and stores layers, masks, and other image manipulation data. Adobe Acrobat files are PDFs, compressed archives use .ZIP or .RAR, and MS Office documents use extensions like .DOCX or .XLSX.

MOV is a file extension for the QuickTime multimedia format developed by Apple, used for storing and playing video and animation files. It can contain multiple tracks for audio, video, and text. Image files use .JPG or .PNG, audio files use .MP3 or .WAV, and MS Office documents use .DOCX or .PPTX.

.PSP is the file extension for PaintShop Pro, a popular image editing software. It stores layered image data and is specifically used for raster graphics, making 'Image File' the correct category. System files use extensions like .SYS or .DLL, while movie files use .AVI, .MOV, or .MP4.

.LNK is the standard file extension for Windows shortcuts. These are small files that point to another file or program location on the system, allowing quick access. They are not hypertext files, temporary files (which use .TMP), or image files.
