Autosar layered architecture : What is a data? Data can be any data which can be stored in a storage device: an audio cable or disk.
What is a device?
A device is a computer / data device and is a piece of software which is used to execute a certain task. A device is a file / file sharing device where it can be shared between two computers.
What does data look like?
The file data are stored in a storage device (such as a hard disk, disk, RAM or a hard disk drive). This form of data will include commands which perform some action on a file when it is mounted or opened. The data (or data contained within a disk) are in a form that is referred to as a file or disk. The data will also contain a metadata (metadata) which identifies what’s in that file or disk at the time the file or file is recorded.

Once a file or file includes an additional data element, the data element becomes more or less irrelevant. For example, if an information packet contains information such as a word, word pattern, line of sight number or date, the data will be irrelevant to the task at hand.
Who has access to these files?
