Explanation:
In order to resist power outages or power fluctuations, you should connect UPS (Uninterruptible
Power Supply) to the server.
UPS (Uninterruptible Power Supply) devices employ a large battery to provide power to a system in
the event of a power outage. The amount of time it can continue to supply power to the system
depends upon the size of the battery, and the power consumption.
UPS is built into the system between the reader and the external power source. The reader is
susceptible to power spikes (caused due to lightning strikes or generator variations). UPS keeps the
readers running in case of a power failure and also protects them against unexpected power spikes.
The UPS helps in keeping data, which may be in the random access memory (RAM) and not yet
pushed up to the application, from being lost and the configuration is not wiped out.
computer. It is loaded by an operating system while starting the computer and it also copies an
application to be run on the computer, such as a word processor or database program. Whenever a
new program is created by a user, the program is temporarily held by RAM and copied to the disk to
save the data permanently.
data on rapidly rotating rigid platters with magnetic surfaces. Strictly speaking, “drive” refers to the
motorized mechanical aspect that is distinct from its medium, such as a tape drive and its tape, or a
floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is
typically a sealed unit with fixed media.
separate hard disk. In the previous operating systems such as Windows 2003, VHD files containing
system images were limited to virtualization and the facility was used with Hyper-V, Virtual Server,
and Virtual PC software when implementing virtual machines. In the Windows 7 operating system,
Virtual hard disks can be created and used on computers that are not virtual machines.
