Final answer:
The computer fits into the desktop category due to its components and capabilities.
Step-by-step explanation:
The computer with the described components and capabilities fits into the desktop category. Desktop computers are typically larger and have a separate monitor, keyboard, and mouse. They are designed to sit on a desk and are not easily portable.
In this case, the computer has an external flat screen monitor and an optical disk drive, both of which are common components of a desktop computer. Additionally, the large capacity hard drive suggests that it is a desktop computer as well, since desktops tend to have more storage space compared to laptops and handheld devices.
