When we talk about TCP/IP, we are talking about a protocol suite designed as a layered approach and used to interconnect computing devices across the entire continent. Internet Protocol (IP) is like the epitome protocol of the entire TCP/IP protocol suite and helps in the delivery of services. This IP is encapsulated into an IP header before your message is sent. Having briefly discussed about the IP protocol and the encapsulation, here is where typical TCP/IP attacks occur.
Explanation:
- IP address spoofing – As mentioned above, IP is encapsulated into packet headers and inside of those headers are information such as IP source and destination addresses. IP source and destination addresses are needed by the routers to determine the best route path. If hackers can get access to the IP layer, they could easily spoof the source address and somehow make it pretend as if it was another legit host.
- TCP sequence number prediction attack– This is very common. TCT/IP protocol suite contains a three way handshake. For instance, when you do a web search, what is happening is that you are sending information to the server. The server will receive this info and send an acknowledgment receipt with the information it received back to you. You will then send an acknowledgment message to the server and communication will be established. In between this handshake, there is a sequence number called ISN that hackers are able to predict from their own host computers, and this sequence number could send malicious packets to impersonate another source host on a network.
- Port Scanning – It is not a technique used to directly launch an attack. However, hackers can use port scanning to scan a target network for exploitable open ports or listening servers.

Answer:
Explanation:
There are many weaknesses/vulnerabilities, some of which are the following...
Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.
Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.
WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.
These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.

Explanation:
Qualitative data describes qualities or characteristics. It is collected using questionnaires, interviews, or observation, and frequently appears in narrative form. For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire.
The answer is B) Template.
Various templates are available in most all desktop publishing programs, from resume templates in Word to Income Statement templates in Excel. Templates are useful for skipping the general "setup" process of making a document, and allow you to focus more on filling the document with the relevant data and polishing it to your specific needs once most of the legwork is done.
Answer:
The code to this question can be given as:
code:
for(i=1;i<=n;i++) //for loop column
{
for(j=1;j<=i;j++) //for loop for rows
{
printf("*"); // print asterisks
}
printf("\n"); //line break
}
Explanation:
We know that variable i,j, and n is already declared and n variable has initialized a value. So, we write the code that is given above. In this code, we use a nested loop. In this code, we use two loops that are a loop (i)for column and j loop for rows. for print asterisks triangle we use two for loop. For that, we use two-variable (i,j) that is already declared. We assign the value in (i) loop that is 0 and checks that (i) is less than equal to n and increment of (i) by 1. In this loop, we use another loop that is (j) loop. It also starts from 1 and checks that (j) is less than equal to (i)and increment of (j) by 1. In that loop, we print asterisks end of (j) loop. In (i) loop we use ("\n") for line break end of (i) loop.
