Hardware-dependent software is like a special book that can only be read by a certain type of person. Imagine that you have a book with special pictures inside, and you have to wear special glasses to see them. The book won't make sense without those glasses. That's how hardware-dependent software works.
When we use a computer or a phone, we need software to make it work. But not all software is the same. Some software is made to work with a specific type of hardware. For example, if we have a printer that is made by a certain brand, we need software that matches that brand of printer. Otherwise, we won't be able to print anything.
Hardware-dependent software is like that. It is software that is made to work with a specific type of hardware. It can't be used with other types of hardware. That's why it's called "hardware-dependent."
For example, if we have a game that is made to work on a PlayStation, we can't play it on an Xbox. The game software is made to work with the specific hardware of the PlayStation. So if we want to play that game, we need to have a PlayStation.
Another example is the software that runs on our phones. Different phones use different types of hardware, so the software needs to be made to work with that specific hardware. We can't use software that is made for one type of phone on another type of phone.
In summary, hardware-dependent software is software that can only be used with a specific type of hardware. It's like a special book that needs special glasses to be read. Without the specific hardware, the software won't work or won't make sense.
