Extension of intranet with added security features

Nickel-cadmium and Nickel-metal hydride batteries

Heavy-Must be occasionally fully discharged to avoid decreasing usage time-Lose 15% of charge within 24 hours, even if not used. This is referred to as self-discharge

is informatics data oriented or process oriented?

Initially process oriented; now data oriented

permanent memory includes

Internal Hard Drive, usually referred to as "C:" in Windows Operating System, External hard drives, flash drives, optical disks

Mainframes

Large computers, serving many users at the same time, using a concept known as time slicing

involves freezing, moving, and refreezing.
