Typically, when an organization purchases Internet access from an Internet Service Provider (ISP), the ISP will grant it

hodyreva [135]

Answer:

(B) A single public IP address that it can use for NAT

Explanation:

Because the IPV4 IP protocol is still used today, the number of available IP addresses is limited (only 4,294,967,296 addresses in the world), for this reason, the most correct practice is the assignment of a single public IP to those companies that acquire services from an ISP, with some few exceptional cases of companies that own several.

So that the company's addressing can be executed successfully, the use of NATs is enabled, this allows the translation of network addresses, allowing the company to have as many private networks as necessary and that these can be communicated Correctly with the global network, the Internet, through the public IP of the company.

What is workflow? how do you create your own workflow?

lana66690 [7]

A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information.

Create a detailed outline of what you want to achieve and sketch a workflow diagram before using workflow chart software or templates. This will help to ensure your chart is accurate and complete. Always consider your process and workflow manageability when inserting logic in your workflow chart. You can use decision symbols, connectors and text boxes. Always confirm the accuracy of your workflow chart with other stakeholders.

(If you need to know what the workflow diagrams layout is just look it up. GL.)

Electromagnetic interference affects cables made from different metals and can corrupt the data running through them. However, Fiber-optic cables are constructed from glass (non-metallic) and transmit pulses of light as signals to transfer data, this means that the cables are most resistant and not susceptible to EMI.
