The answer is: all of the above (a, b, c, d).
Explanation for each option:
a. DVDs: Correct. DVDs can be used to create a Windows system image, although this method is less common due to the large size of system images and the limited storage capacity of DVDs.
b. Internal hard drive: Correct. An internal hard drive can be used to store a Windows system image. However, it is generally recommended to use a separate partition or a different internal drive to avoid data loss if the primary drive fails.
c. External hard drive: Correct. An external hard drive is a common and convenient option for storing a Windows system image. It provides ample storage space and can be easily connected and disconnected from the computer.
d. Network drive: Correct. A network drive can also be used to store a Windows system image. This allows for the system image to be stored on a network-attached storage (NAS) device or a server, providing centralized and potentially more secure storage.
Summary:
All the listed storage media options (DVDs, internal hard drive, external hard drive, and network drive) can be used to create a Windows system image.
