Answer:
Hackers frequently spend long hours examining the types and structures of targeted systems because they must use guile, or fraud to bypass the controls placed on information owned by someone else.
Explanation
The perception of a hacker has evolved over the years.
- The traditional hacker profile was a male, aged 14 to 18.
- 76% of hackers are men whose ages are between 14 years (8%) to 50 (11%). The average age is 35 years (43%).
- A hacker is persevering, patient, creative, bright and having a passion for what he does.
- Hackers today can be expert or novices.
- The experts create the software and schemes to attack computer systems.
- While the novices merely use software created by the experts.
Answer:(c) abstract class A { abstract void unfinished(); }
Explanation:
A legal abstract class must have the keyword abstract before the class and an abstract class has abstract functions with the keyword abstract written and a void as the return type.
Answer:
Study Python’s help on range to determine the names, positions, and what to do with your function’s parameters.
Use a default value of None for the two optional parameters. If these parameters both equal None, then the function has been called with just the stop value. If just the third parameter equals None, then the function has been called with a start value as well. Thus, the first part of the function’s code establishes what the values of the parameters are or should be. The rest of the code uses those values to build a list by counting up or down.
Answer:
A. The mathematical formula for finding the area of a circle.
D. Instructions for setting up a new DVD player
E. A series of steps that moves a "lighting bot" around to turns on lights.
Explanation:
Algorithm is a systematic procedure (or process) that produces the answer to a question or the solution of a problem in a finite number of steps.
Option A is an algorithm. The mathematical formula for finding the area of a circle gives a solution to a problem. The problem is finding area of a circle and the formula gives the step by step procedure finding the area of a circle.
Option B is not an algorithm. Option B just provide a list of your favourite animals and it doesn't answer a question we know about.
Option C is not an algorithm. A problem statement is still a problem with no solution whereas algorithm provides solution
Option D is an algorithm. It provides the step by step procedures for setting up a new DVD player
Option E is an algorithm. It provides a series of steps that moves a lighting bot around to turns on lights, so it provides a solution.
<span>Middleware for cloud database applications is commonly written as scripts—short sections of code written in a programming or scripting language that are executed by another program. A script language is used for server side scripting language that can change a specific data on the server. Examples of these are PHP, JSP, Perl, Python, etc.</span>
