Displaying your main folders is done with File Explorer, the Windows file management app. File Explorer is built to browse drives and the top-level folders you use most, like Documents, Downloads, Desktop, and Pictures, all in one window with a navigation pane for quick access. You can open it quickly by pressing Windows key + E, clicking the File Explorer icon on the taskbar, or selecting File Explorer from the Start menu. The other options serve different purposes: Task Manager shows running programs and system performance, while Control Panel and Settings handle configuration and system options rather than file navigation.

File extensions indicate the type of data a file contains, and a name ending with .jpg signals a JPEG image format used for graphics and photographs. JPEGs store image data and use lossy compression to reduce file size while keeping picture quality reasonable, which is why this file is categorized as a graphics image file. It isn’t a text document (like .txt or .docx), an audio file (like .mp3 or .wav), or an executable file (like .exe).

SDLC stands for Software Development Life Cycle, a framework that guides the entire process of creating software from idea to long-term support. The main phases here are planning, analysis, design, implementation, testing, deployment, and maintenance. Each step has a clear purpose—planning sets goals and scope, analysis gathers the requirements, design outlines the solution, implementation builds the code, testing checks that it works correctly, deployment puts the software into use, and maintenance handles fixes and updates after release. This sequence is the best match because it reflects a comprehensive, widely used structure that covers all stages of delivering a workable, maintainable product. The other options use nonstandard terms or leave out essential phases, so they don’t describe the complete process the way this set does.

Virtual memory extends RAM by moving pages between memory and disk when RAM gets full. The part of the hard drive set aside for this swapping is the swap file. Cache is used to speed up data access and isn’t the storage area used for virtual memory. RAM is the actual physical memory, not disk storage. In Windows this on-disk area is called the page file, but the broader term for the on-disk space used for swapping is swap file—the key idea being the disk space that holds pages moved out of RAM.
