Answer:
(A)AES
Explanation:
WPA2 (Wi-Fi Protected Access 2) is a security protocol which was developed by the Wi-Fi Alliance in 2004. It was used to replace the security protocol of WEP(Wired Equivalent Privacy) and WPA.
Unlike the previous security protocol, WPA2 uses the Dvanve Encryption Standard (AES) instead of the RC4 stream cipher. WPA3 has been developed but it is not yet widely in use.
Answer:
Option (c)
Explanation:
Parallel arrays are those arrays which are used to store some records which needs more than one array to hold a entry but are interrelated and should be accessed by same index number. As they are of different data types so can't be stored as multi-dimensional array or matrix. Then parallel array comes to rescue. For example : Details of a student.
Name, age and ID of a student needs to be stored. So, three arrays can be made and each entry should be accessed by same index number.
Answer:
is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer.
2. Data link Layer.
3. Network Layer.
4. Transport Layer.
5. Session Layer.
6. Presentation Layer.
7. Application Layer.
Hence, the Open Systems Interconnection (OSI) Reference Model is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Additionally, each layer has its unique functionality which is responsible for the proper functioning of the communication services.
Hello,
Well my advice for Sara when using the web would be 3 things.
1: Never tell anyone where you live,Your name, Or any other personal information.
This is important as it will keep you safe and others that are in your family.
2: Get anti virus hardware on your devise.
This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.
3: Make sure to keep your passwords saved on paper.
I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.
Have a great day!
The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.
Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.
However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
