1) Safety Notice

(1) An electric leakage related safety

Electric leakage is the flow of electricity to the ground through electrical wires due to ripped coating or bad

insulation. Electric leakage can cause electric shock or fire, which in turn may lead to casualties and loss. It

can also result in excessive electric charges.

(2) An electric leakage prevention

- Do not separate or disassemble the system even though system is shut down in a AC power supplies.

In that situation, system could be damaged.

- The electricity could be generated in winter or a dry space, prepare the leakage prevention for the

electricity when you try to disassemble.

- Do not use in strong magnetic space.

- Use the proper adapter and battery.

- Insertion of including saline could cause the leakage.

If you don't keep those things, there is a danger of electric shock, system damage and so on.

4) Glossary

Bad Sector

An area on a hard disk or floppy disk that cannot be used to store data, because of a

manufacturing defect or accidental damage. A floppy or hard disk saves data in units and the

smallest unit of storage on a disk is a sector. A bad sector means a sector that is damaged and

cannot be used to write or read data.

BIOS

An acronym for Basic Input/Output System. A set of instructions stored on a read-only memory

(ROM) chip which handles all input-output functions. The BIOS communicates between the operating

system and the computer's hardware. This is a part of the computer f irmware (computer dedicated

software).

The BIOS allows the computer's hardware and the operating system to communicate with application

programs and peripheral devices as well as providing the fundamental services required for the

computer's operation. To view or change the BIOS settings, press the "Del" key when the system is

booting up.

Boot Sector

The very first track (track 0) on a hard drive of an IBM compatible PC. If the power is turned on,

the booting software reads the first block of the boot sector which contains a very short program (in

the order of a few hundred bytes) which will load and start running the operating system properly.

Bus Mastering

Bus mastering is a feature that enables a CPU extension board or software controller connected to

the bus to communicate directly with other devices on the bus without going through the CPU.

Although the CPU generally controls data communication over the bus (which lowers the data rate),

some high-speed devices may communicate with each other without going through the CPU. To

resolvethisproblem,amicroprocessorinstalledonanextensionboardorapieceofsoftwaremust

take control of the data transfer over the bus. By taking over some of the work of the system

microprocessor, the bus master creates a multiprocessing environment and increases the overall

system performance. This technology is called bus mastering.

Cache

A cache is temporary high speed memory designed to speed up access to resources. It is similar to

RAM but is much faster than RAM or a hard disk drive. A cache is used to reduce the wait time

caused by the difference in the data rate between two different types of storages such as the hard

disk and the RAM.
