Final answer:
Standard computer cases usually feature several internal drive bays for storage devices and a few external drive bays for CD/DVD readers. The exact number of bays depends on the case size and design. These bays allow for secure installation and easy access to data storage devices.
Step-by-step explanation:
A standard computer case typically includes a variable number of internal drive bays, depending on the size and design of the case. The number of internal drive bays can range from one or two in smaller cases to three or more in mid-sized and larger cases. This allows users to install hard disk drives, solid-state drives, or other storage devices inside the case. These internal drive bays are not visible from the outside and provide a secure and stable environment for data storage devices.
Additionally, a standard computer case also includes a small number of external drive bays. These are typically located on the front panel of the case and are designed to accommodate CD/DVD readers and writers, allowing the user to easily access the drives for loading or removing discs without having to open the case.
The CD players and hard disk drives, as mentioned in the provided information, show the complex electronics involved. The CD player facilitates reading from optical media, while the hard disk drive utilizes a stylus (read/write head) for accessing information stored on the magnetic disk. Both drive types represent how data is read and written in different storage form factors.
