Answer: hello your question lacks the required option, below are the missing options

A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.

B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.

C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.

D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.

answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )

However, sitting in a corner of the store, a hacker had just placed up an open “rogue” wireless hotspot posing as the coffee shop’s wireless network. When Sarah logged onto her bank’s website, the hacker hijacked her session and gained access to her bank accounts. Another term for rogue wireless hotspots exists as “evil twin” hotspots.

<h3>What is meant by wireless network?</h3>

A computer network is referred to as a wireless network if radio frequency (RF) links are used to connect network nodes. A common solution for households, companies, and telecommunications networks is wireless networking. Wi-Fi is a wireless networking technology that enables printers and video cameras to connect to the Internet as well as computers (laptops and desktops), mobile devices (smart phones, wearables, etc.), and other devices.

Increased Mobility: Wireless networks give mobile users access to real-time data, enabling them to move freely across the premises of your firm without losing network connectivity. This improves collaboration and production across the entire organisation, which is not achievable with traditional networks.
