Answer:
a. quantum computing and telecommunications
Explanation:
Both quantum computing and telecommunications need materials with specific optical, electrical, and magnetic properties to advance, and nanotechnologies open the opportunity for nanomaterial with incredible properties. From antennas with special magnetic properties to faster optical fiber from more stable material to store qubits to super thermal insulators, nanotechnologies will change the way we build and design telecommunication systems, and it will allow us to build stable and reliable quantum computers.
First three bytes of the ethernet address exists assigned to vendors to identify the equipment.
<h3>What is Ethernet address?</h3>
A media access control address stands for a unique identifier allocated to a network interface controller for usage as a network address in communications within a network segment. This use exists as standard in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
This address exists as the identifying mark that allows a networked computer to communicate with the Internet. The ethernet address exists how we can associate an “IP address” to an individual computer — without this– number, there's no form to access any servers, websites, email, etc.
The first three bytes (pairs of hexadecimal characters) of any unicast address include that vendor address component of the MAC address. The staying three bytes carry the serial number of that vendor's interface card. Dell, Inc. Apple, Inc.
Hence, first three bytes of the ethernet address exists assigned to vendors to identify the equipment.
