If computers and monitors are set in ‘sleep’ mode when not in use, the energy cost is reduced approximately by: Correct Answer 40 percent

Screen savers do not reduce the use of power by your computer; once your screen saver kicks in, your monitor will draw its full power load.

All users, whether on desktops or laptops, should configure their computers to use the power-saving or energy star modes that shut down power to the monitor, hard drive, and computer itself after periods of inactivity.

Putting your computer in sleep mode allows it to use substantially less power, allows it to respond to some types of network activity, and allows you to not power off the computer.

A computer display in full use gobbles up 65 watts – but still uses 25 watts when in sleep mode. When off it uses 0.8 watts.

Setting computers, monitors, and copiers to use sleep-mode when not in use helps cut energy costs by approximately 40%.

Your network contains 10 domain controllers, 10 member servers, and approximately 1,000 client computers. All the servers run Windows 2000 Server, and all the client computers run Windows 2000 Professional. Two of the domain controllers act as DNS servers. Users of client computers use file sharing to grant access to files stored locally. The network has 10 subnets and uses TCP/IP as the only network protocol. You want to configure the network so that all computers can resolve the addresses of all other computers by using DNS. Client computers must be able to register and resolve addresses if a server fails. How should you configure the DNS servers?

P. Girls who were checking social media also reported to be less happy and more anxious; however, boys didn’t report the same feelings. Q. In girls, the researchers said, the negative effects were due to disrupted sleep, cyberbullying and to some extent, lack of exercise. R.
