Digital certificates are issued by internal or external resources called a certification authority.
Western Digital and SeaGate are the top manufacturers of hard drives, internal and external.
A digital vernier is mainly used to measure lengths or distances very accurately. These may be internal or external distances. The distance may be read as either metric or imperial.
A digital caliper is commonly used to measure the internal and external diameters of a test tube with precision. This tool allows for accurate readings by using its jaws to measure diameters and display the measurements digitally.
No. An I/O device can be either internal (installed inside the computer case) or external (installed outside the case). Internal: network card, sound card, video capture card, and video card.

A: [practically all commercial digital meter have a 11 mega ohm input impedance but there are special meters that can be used to measure leakage current and they have impedance high enough to measure nano amps. Even an oscilloscope will have these kinds of impedance such that the reading is not influenced by external loading
