Privilege escalation describes a situation where an attacker with some level of restricted access is able to, without authorization, elevate their privileges or access level. For example, a standard computer user may be able to exploit a vulnerability in the system to gain access to restricted data; or even become "root" and have full unrestricted access to a system. Penetration testers are ethical hackers who test the security of systems, networks and applications, seeking vulnerabilities that could be exploited by malicious actors. Related to end-user training, digital hygiene or cyber hygiene is a fundamental principle relating to information security and, as the analogy with personal hygiene shows, is the equivalent of establishing simple routine measures to minimize the risks from cyber threats. The assumption is that good cyber hygiene practices can give networked users another layer of protection, reducing the risk that one vulnerable node will be used to either m

Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that itself but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy. Energy can be neither created nor destroyed but only changed from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics. For example, when a box slides down a hill, the potential energy that the box has from being located high up on the slope is converted to kinetic energy, energy of motion.

This tab can include information on education, training, work experience, licensing and certification, and important qualities that are required or helpful for entering or working in the occupation. The What They Do tab describes the typical duties and responsibilities of workers in the occupation, including what tools and equipment they use and how closely they are supervised. This tab also covers different types of occupational specialties. Waiters and Waitresses Waiters and waitresses take orders and serve food and beverages to customers in dining establishments. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $36,630, and the highest 10 percent earned more than $98,070. Some food service managers start working in industry-related jobs, such as cooks. The foodservice version is packaged in a much larger industrial size and often lacks the colorful label designs of the
