a network engineer is configuring cellular phones for new employees. what communication-based phones use time division multiple access to declare time slots?

Answers

Cellular phones that use time division multiple access (TDMA) to declare time slots are commonly used in digital communication networks.

What is TDMA?

TDMA is a multiplexing technique that allows multiple users to share a single frequency channel by dividing the channel into a series of time slots. Each user is assigned a specific time slot, and the users take turns transmitting their data during their assigned time slot.

This allows for efficient use of the available bandwidth and enables multiple users to communicate simultaneously over the same channel. TDMA is commonly used in cellular networks, as well as in other types of digital communication systems such as satellite and wireless local area networks (WLANs)

Answers

The PC is not receiving a valid IP address from the network's DHCP server and that it is using an automatic private IP addressing (APIPA) address.

What is IP address?Each device connected to a computer network that uses the Internet Protocol is given a unique numerical label known as an IP address. In most networks, IP addresses are assigned to devices dynamically by a DHCP (Dynamic Host Configuration Protocol) server, which assigns a unique IP address to each device on the network.If a device is unable to obtain a valid IP address from the DHCP server, it may use an APIPA address instead. APIPA addresses are reserved for use in situations where a device is unable to obtain a valid IP address from the DHCP server, and are in the range of 169.254.0.0 to 169.254.255.255. When a device uses an APIPA address, it means that it is unable to communicate with the DHCP server and may not be able to access the internet or other resources on the network.

The strategies that can be used in order to prevent intoxication are as follows:

Make water available and have staff offer it regularly to encourage patrons to pace their alcohol consumption. Encourage patrons to stop drinking or consume non-alcoholic drinks before they reach the point of undue intoxication. Lower the entertainment noise level to allow patrons to talk; this slows down drinking.

Once a patron becomes intoxicated, they must leave the premises and not be allowed back in. While they may have accepted your offer of a non-alcoholic drink, they will still need to leave.
