Answer:
The main difference between LAN, MAN and WAN is the scope and coverage of the networks. LAN (Local area network) is usually used to connect computers in smaller distances such as in a building or in offices. They use various topologies such as bus topology, ring topology, star typology etc to connect the computers and share information only among the computers connected in LAN. A Metropolitan Network covers larger coverage than LAN and is usually used for connecting a city rather than single organization. A Wide Area Network is collection of networks or many LANS. The perfect example of WAN is internet which connects thousands and millions of networks. Another factor which distinguishes between LAN, MAN and WAN is that LAN and MAN are owned by certain entities such as government, educational institutions or organizations whereas WAN (i.e. Internet) is not owned by anyone.
Answer:
The answer is "HTML".
Explanation:
We will suggest him to learn HTML language because It stands for HyperText Markup Language. It is a markup language that uses a build a web page and these sites are normally viewed on the web browser.

- Each one of these kinds of content is tagged and described by HTML, which uses a web browser can display it correctly.
Answer:
Distributed DOS attacks.
Explanation:
Computers in a network or the network itself is are prone to cyber attacks. A cyber attack is a concept of taking advantage of computer network vulnerabilities, to retrieve information from the target source. An example of these types of security attacks is the denial of service (or DOS) attacks.
The DOS or the distributed DOS attack prevents users form accessing or requesting a service that they are legitimately allowed, by flooding the target system with superfluous resource request from millions of computers, controlled by the attacker.
Answer:
The best reading techniques are the SQ3R technique, skimming, scanning, active reading, detailed reading, and structure-proposition-evaluation.
Explanation:
Answer:
The solution code is written in C++
- float cellPhone(int m, int tx){
- float COST_PER_MIN = 0.1;
- float COST_PER_MESSAGE = 0.2;
-
- float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
-
- return bill_amount;
- }
Explanation:
Firstly, declare a function named cellPhone() that takes two input parameters, m and tx (Line 1).
Since the policy of the carrier company is not given in the question, I make a presumption that the cost per minutes is $0.10 and the cost per message is $0.20 (Line 2- 3).
Next, apply the formula m * COST_PER_MIN + tx * COST_PER_MESSAGE to calculate the total bill (Line 5) and return the bill_amount as function output (Line 7).
