Step 1
Identify three ways that Xander can make use of the file management facility.
Answer
-
Xander can use the file management facility to create new files. This allows him to save documents, images, or any other data he generates.
-
Xander can organize files into folders, making it easier for him to categorize and retrieve information when needed.
-
Xander can delete files that are no longer necessary, which helps in managing storage space efficiently.
Step 2
Explain how the compression software will compress the image file.
Answer
The compression software reduces the size of an image file by eliminating redundancies in the image data. This process often involves encoding techniques that minimize the amount of data required to represent the image. For example, it might use algorithms that remove unnecessary color information or apply lossless or lossy compression methods, where lossless retains all the original data but lossy sacrifices some quality for a smaller file size.

Answer
I chose the smart watch as an example of an embedded system because it is designed to perform a specific function, such as tracking health metrics, and is typically built into the device. Unlike a laptop, which is a general-purpose computing device, the smart watch runs on dedicated software that controls its limited functionalities, making it an embedded system.
