Many types of renewable energy resources such as wind and solar energy are constantly replenished and will never run out.

A UPS (Uninterruptible Power Supply) is a device that provides battery backup when the electrical power fails or drops to an unacceptable voltage level.

Small UPS systems provide power for a few minutes; enough to power down the computer in an orderly manner, while larger systems have enough battery for several hours.

A Contact force is a force applied to a body by another body that is in contact with it. Contact force acts on a point of direct contact between the two objects. This force can either be continuous as a continuous force or can be momentary in the form of an impulse. Contact force is governed by Newton’s Laws.

Examples :: Contact force is responsible for most of the interactions we experience in the daily life.

1. Writing your name with a pen, pushing a car up a hill, lifting an object, etc...

2. Kicking a ball, hammering a nail, etc...

are some of the everyday examples where contact forces are at work.

In the first case, the force is continuously applied by the person on the car or pen or an object while in the second case the force is delivered in a short impulse.

Contact forces are often decomposed into orthogonal components

one perpendicular to the surface in contact called the normal force, and

one parallel to the surface in contact, called the friction force.

AutoSys is an automated job control system for scheduling, monitoring, and reporting. These jobs can reside on any AutoSys-configured machine that is attached to a network.

However, in real business, you need to fire jobs not just based on scheduled time, but also based on events (like an arrival of a file), and, based on the success or failure of other jobs. Autosys is a total job scheduling solution that allows you to define these events, dependencies, time schedules, alerts, etc, making it a complete data center automation tool.

Deleted files are not permanently removed from the hard drive or the computers memory. Before they are permanently removed from the system they are stored in Recycle Bin. Recycle Bin is a folder or directory where deleted items are temporarily stored. It is also called as trash.

Million Instructions Per Second is a method of measuring the raw speed of a computer's processor. MIPS measures roughly the number of machine instructions that a computer can execute in one second.

All of the options given are synonyms of RUN.

Hence, Race, Amble, Lope are similar in meaning to the word Run.
