Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.
Answer:
Wireless WAN like VSAT and WIMAX.
Explanation:
WAN or wide area network is a form of network meant for long distance communication between sites. It is made up of interconnecting local area networks spanning from a town to global communication of branches in an organisation.
For local area networks to be connected together to make a WAN, a dedicated high speed cable connection must be installed between sites. Fiber optics, among others, is the widely used dedicated WAN backbone connection. Cable connections are faster and moderately secure.
A VSAT is a wireless network connection method, where networks are connected using satellite dishes in remote networks, in the line of sight to a satellite, for WAN communication. It is not as fast or as secure as the cable connection, but can be used in remote area, where ISP in not available.

Answer: False
Explanation:
Digital certificate is defined as entity identification in digital form that is used by a user or firms to share their information along with authentication and security. It uses public key cryptographic technique and so it is also know as public key certificate.
- Digital signature is the signature that is done digitally to secure data or document.It maintains security of the content present in message of information that is being exchanged through e-signature.It follows encryption technique for maintaining authenticity.
- Therefore, digital signature is the signing feature that protects macro after being made to maintain its authenticity.
- Thus, the given statement is false.
