Answer:
They use principles of light to scan document
Magnetic scanning
Explanation:
Depends on how deep you're willing to go to really,
You need one of a few arrangements of flip flop circuits to keep 1-bit state.
Going deeper, you need either NAND, or NOR gates(or a bunch of other ones) and connectors.
Even deeper, you'll require diodes or transistors to build the logic gates.
Beyond that is particle physics.
True; synchronous means existing or occurring at the same time (I really don't know if that's a question but oh well)
Answer:
The correct answer to the following question will be "Data-in-use".
Explanation:
- Data-in-use is an IT term referring to active information that is usually preserved in a semi-persistent physical state in RAM of computer, CPU registers or caches.
- It might be created, modified or changed, deleted or accessed via different endpoints of the interface. This is indeed a useful term for IT departments to pursue institutional defense.
Therefore, it's the right answer.
A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
