Description |
Registry |
The
Registry is a database used by Windows95, 98 and NT to store
user preferences, setup, device, and system configuration.
The Registry files are vital to the proper execution of the
Operating Systems. |
Reduced
Write Current |
In
older hard drives, there were the same number of sectors near
the center of the platter or disk as there was in the outer
tracks. To get the same number of bits in each sector, the
bits had to be placed closer together in the center tracks.
Using the same magnetic current to write information to the
center tracks sometimes affected adjacent data. To solve this
problem, a method was devised that reduced the current as
the heads got closer to the center. |
Read/Write
Head |
A
small electro-magnet in a drive that skims above the surface
of a disk or platter and reads information from, or writes
data to, the disk. |
RAM |
Random
Access Memory is the workspace of your computer. It's the
area that stores the information and data for processing by
the computer's CPU. Retrieving data from the hard drive is
much slower, but once the data is loaded into RAM, it can
be accessed instantly and randomly. RAM is volatile, which
means that once you turn off the power, all data in memory
disappears. RAM is stored in chips on small circuit boards
called SIMMs or DIMMs, that attach to the motherboard. |
Root
Directory |
The
main or first directory created on a drive or disk when it's
formatted by the Operating System. |
Resolution |
The
image on your computer's monitor is made up of tiny dots called
pixels (picture elements). The total number of pixels used
to draw the image on the screen determines the Resolution
and is defined by the number of pixels across and the number
of pixels down. i.e. 640x480. |
