Question

Match the file extensions with the appropriate file. A. txt B. \(m p 3, a u\), and wav C. gif, tiff, and jpg D. doc and wp 3 E. java, c, and cpp Audio file

Short answer

Use file extensions ".mp3", ".au", and ".wav" for audio files.

Step-by-step solution

Identify File Extensions for Each Type

We need to understand what each set of given file extensions typically represents: 1. ".txt" is for text files. 2. ".mp3", ".au", and ".wav" are for audio files. 3. ".gif", ".tiff", and ".jpg" are for image files. 4. ".doc" and "wp3" are for document files. 5. ".java", ".c", and ".cpp" are for programming source code files.

Identify Audio File Type

From the list, the extensions ".mp3", ".au", and ".wav" correspond to audio files.

Key concepts

Audio Files

Audio files are digital files that store sound. There are various file extensions commonly associated with audio files. Each format has unique attributes, affecting sound quality and file size.

• .mp3: One of the most popular audio file formats, widely used for music. It compresses audio files to reduce their size, making them ideal for streaming and storage, though it may lose some audio quality in the process.
• .au: An older audio format often used in the UNIX operating system. It is less common today, but still recognizable in certain systems and applications.
• .wav: Associated with Microsoft and IBM, this format is uncompressed, preserving audio quality but resulting in larger files. It is often used in professional audio environments where quality is paramount.

Understanding these extensions helps in selecting the right format for your needs, whether prioritizing quality or storage efficiency.

Text Files

Text files are one of the simplest types of digital files, primarily containing plain textual data. Identifying a text file is straightforward as it typically ends with the ".txt" extension.

• .txt: These files are used to store plain text without any formatting. They're versatile and can be opened in any text editor or word processing software, making them perfect for simple note-taking or sharing unformatted text.

Text files are ideal for situations where only the text matters, and formatting is unnecessary, such as code snippets, logs, or simple documents.

Image Files

Image files are used to store graphic data, and they come in various formats with different characteristics.

• .gif: Supports animation and transparency. Used extensively for short, looping animations on the web.
• .tiff: Known for high-quality images without compression loss, making it suitable for professional photography and print.
• .jpg: The most common format for digital photos. It compresses images to save space and is compatible with most devices and software.

Different image file formats serve specific purposes, from high-quality prints to efficient web distribution.

Document Files

Document files are primarily used for storing formatted text, images, and other data consistent with documents.

• .doc: A proprietary format by Microsoft commonly used in Word documents, supporting rich text, formatting, and multimedia.
• wp3: An older format used by WordPerfect software, less common today but significant historically for document writing.

Choosing the right document file format depends on the desired compatibility and the need for specific features like style formatting.

Programming Files

Programming files contain source code written in programming languages. These files are crucial for software development.

• .java: Source files for Java programs, used to write applications that run on the Java platform.
• .c: A file extension for source code written in the C programming language, often used in system software and embedded firmware.
• .cpp: Related to the C++ language, extending C with object-oriented features. These files are used in large applications where C++ is preferred for its object-oriented capabilities.

Recognizing these extensions helps developers navigate and organize code effectively during project development.
