It is an input and an output. The scanner scans the paper which is the input ,and the output is when the printer prints the paper.
Answer:
55
Explanation:
Given the codes as below:
- for (int a = 0; a < 10; a++)
- {
- for (int b = 10; b > a; b--)
- {
- System.out.print("#");
- }
- }
There are two layer loops in the code. The outer loop (Line 1) will run for 10 iterations by traversing through a = 0 to a=9. However, the inner loop (Line 3) will run for 10 + 9 + 8 + 7 +...+ 1 = 55 iterations.
Since the print statement is within the inner loop (Line 5) and therefore the number of printed "#" symbols is dependent on the number of iterations of the inner loop. There will be 55 "#" symbols printed.
A and B are out because Charlie knows his problem is he is not going to finish in time. D is out because he hasn't talked to his manager yet. so only choice left is C. decide if he should talk to his manager about the problem he now knows
Store b. This will have her paying 36.00 for the rug. Store A she will pay 40.50
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
