Answer:
A word count is a numerical count of how many words a document contains.
Explanation:
Most word processors today can count how many words are in a document for the user.
When you type in a document, Word automatically counts the number of pages and words in your document and displays them on the status bar at the bottom of the workspace.
Word also counts pages, paragraphs, lines, and characters.
Understanding subnet mask is very important in network infrastructure. It is important because it will tell all the information needed to configure the machine, information such as hostname, port address, the number of ports and broadcast address. Subnet mask tells you everything.
Answer:
Gain (dB)=10 log(O.P./I.P)
Also, the loss(dB) = -gain(dB) = 10 log(I.P/O.P)
which is, 50 = 10 log(I.P./10nW)
and hence, anti-log(5) = I.P/10 nW
And thus the power required by the source is antilog(5)*10nW = 1 mW
Note: Power required by the receiver is the O.P. and the power required from the source is the I.P.

Attackers frequently use ACK scans to circumvent a firewall or other filtering tools. During a NULL scan, all packet flags are enabled. The most recent versions of Nessus Server and Client are compatible with Windows, Mac OS X, FreeBSD, and the vast majority of Linux variants.
<h3>What is ack scan ?</h3>
- ACK scans are used to identify hosts or ports that have been blocked or are resistant to other types of scanning. An attacker uses TCP ACK segments to learn about firewall or ACL configuration.
- Attackers probe our router or send unsolicited SYN, ACK, and FIN requests to specific UDP/TCP ports.
- TCP ACK Scan sends an ACK message to the target port to determine whether or not it is filtered.
- On unfiltered ports, a RST reply packet will be sent for both open and closed ports. Filtered ports will either generate no response or generate an ICMP reply packet with an unreachable destination.
- The TCP ACK scanning technique attempts to determine whether a port is filtered by using packets with the ACK flag set.
