The way to type an absolute reference formula in excel is by: Before the column name and row number, for example that is $E$4, add the dollar sign ($). The equation will now be = B2*$E$4.
How can an absolute reference formula be added to Excel?For adding absolute cell references to your calculations, there is a shortcut available. Press the F4 key to continue typing your formula after entering a cell reference. The cell reference is automatically made absolute by Excel! Excel will cycle through each possible absolute reference by pressing F4 repeatedly.
Therefore, Simply pick the cell reference(s) you want to change and click the F4 key to use the shortcut. Holding down the Shift key while pressing the F4 key will select all of the cell references you want to change at once.

Since you want to identify all devices on a network along with a list of open ports on those devices. you want the results displayed in a graphical diagram. the tool that you use is Port scanner.
Why would someone use a port scanner?Finding open ports on a network that might be receiving or transferring data is a process called port scanning. In order to find vulnerabilities, it also entails sending packets to particular ports on a host and examining the answers.
Note that Only when used with a residential home network or when specifically approved by the destination host and/or network are network probing or port scanning tools allowed. Any kind of unauthorized port scanning is absolutely forbidden.

different between in class and structure
Answer:
Structures are value types; classes are reference types
Now suppose you were charged with putting together a LAN to support the occasional exchange of data between nodes (in this part of this question, there is no voice traffic). That is, any individual node does not have data to send very often. How well suited are these four protocols (TDMA, CSMA, slotted Aloha, and token passing) for this scenario? Provide a brief (one sentence) explanation of each answer.
TDMA and token passing will work well because it provides a constant bit rate service of 1 slot per frame.
What is LAN?A local area network is the computer network which connects computers within a specific geographic area, like a home, university campus, etc. A wide area network, on the other hand covers a greater geographic distance, and also typically involves leased telecommunication circuits.
Due to collisions and the variable amount of time required to access the channel for example, channel access delays can be unbounded, CSMA will not work well here unless channel utilization is low and the need for voice packets to be played out synchronously and with low delay at the receiver.
Slotted Aloha won't work well too. Token passing works well in this case because each station gets a turn to transmit once per token round, resulting in an essentially constant bit rate service.
