Computer Essentials - Section 4 Quiz

Emptying the recycle bin permanently deletes all files in it so they cannot be restored. When the recycle bin is emptied, the files are not just moved to a different location, but they are completely removed from the system, freeing up the storage space they occupied. This action is irreversible, and once the recycle bin is emptied, the files cannot be recovered using normal methods.

The best practice in naming a file containing student results for Faculty of Pharmacy for 2015 is "Student Results - Faculty of Pharmacy - 2015". This naming convention provides clear and specific information about the contents of the file, including the type of data (student results), the relevant faculty (Faculty of Pharmacy), and the year (2015). This naming convention helps in organizing and identifying the file easily, especially when there are multiple files or when searching for specific information.

The internal hard disk typically has the largest storage capacity compared to the other devices listed. USB flash drives, DVDs, and CD-ROMs have limited storage capacities, whereas internal hard disks can store much larger amounts of data. This is because internal hard disks are designed to be the primary storage component of a computer system, capable of holding operating systems, software, and large amounts of files and data.

In terms of file size, 1 GB is indeed larger than 2 MB. This is because 1 GB is equal to 1024 MB, so it is significantly larger than 2 MB.

The correct answer is "Hierarchy." Hierarchy is a method of organizing files where they are arranged in a tree-like structure, with parent and child relationships. This allows for easy navigation and categorization of files based on their relationships. In a graphical representation, hierarchy is often depicted with a main root or parent node, branching out into sub-nodes or child nodes. This method is commonly used in file systems and databases to organize and manage data efficiently.

Compression software reduces the size of a folder and any files it contains by compressing them. This process involves reducing the amount of data required to store the files, making them smaller in size. By using compression software, the folder and files can be compressed into a single archive file, which takes up less space and can be uploaded faster.

Blu-ray Disc is the correct answer because it is specifically designed to store high definition video. Blu-ray technology allows for larger storage capacities and higher data transfer rates, making it ideal for storing high-quality video content. Additionally, Blu-ray Discs are capable of playing back high definition video with superior picture and sound quality compared to other storage mediums like CD-ROMs, monitors, or flash memory.

The correct answer is Terabyte, Gigabyte, Megabyte, Kilobyte. This is because file size is typically measured in bytes, with each unit representing a different magnitude. The Terabyte is the largest unit, followed by the Gigabyte, Megabyte, and Kilobyte, which is the smallest unit. Therefore, the correct order is from largest to smallest.

File compression is the process of reducing the size of a file for transmission. This is achieved by using various algorithms and techniques to remove unnecessary or redundant data from the file, resulting in a smaller file size. This smaller file size makes it easier and faster to transmit the file over a network or store it on a disk.

In a hierarchical file system, the correct order is Drive, Folder, Sub-folder, File. This means that the top-level structure is the Drive, followed by the Folders within the Drive, then Sub-folders within the Folders, and finally the Files within the Sub-folders.
