Answer:

A bread board is prototyped (manufactured) in a way where it is less permanent than a pcb (printed circuit board) or an even more permanent pcba (printed circuit board assembly). Bread boards are typically the first step to creating a finished circuit because electronic components are easier to test and take apart when needed; design and investigation can be made effectively as no soldering connections are required. Whereas a circuit board is used for the further finished products because they don't have sockets like the bread board and so there is little room for error and mistakes.

A customer reports that recently several files cannot be accessed. The service technician decides to check the hard disk status

Lyrx [107]

Answer:

Back up the user data to removable disk

Explanation:

Before you work on a computer, especially anything that has to do with files not accessible, this might need to format the system because it might either be a virus or other forms of malware. Since backup was done to a different logical partition on the disk, the first thing to do before performing any diagnostic procedures on the disk is to back up the user data to a removable disk in order not to lose the information in the system.
