The correct IEEE standard for wireless networking in a business environment is 802.11. This series of standards defines the protocols for implementing wireless local area network (WLAN) communications in various frequencies, including 2.4, 5, and 60 GHz bands. The 802.11 standards are widely used worldwide and form the basis of wireless network products that are marketed under the Wi-Fi brand. Frank and his colleagues should familiarize themselves with the
802.11 standards to set up a secure wireless network for their firm.

Asymmetric encryption, also known as public-key cryptography, uses a pair of keys--a public key and a private key--to encrypt and decrypt data. This method is widely used for securing small amounts of data, such as digital signatures. In asymmetric encryption:
The public key is used to encrypt the data.
The private key is used to decrypt the data.
Digital signatures utilize asymmetric encryption to ensure the integrity and authenticity of a message. When a sender signs a document with their private key, the recipient can verify the signature using the sender's public key, confirming that the document was indeed signed by the sender and has not been altered.
