How secure is password protected ZIP file?
About Security
Main security methods
are 128-bit AES and 256-bit AES. These numbers refer to the size of the
encryption key that is used to encrypt the data. 256-bit AES is stronger than
128-bit AES, but both of them can provide significantly greater security. A minor
advantage of 128-bit AES over the 256-bit AES is that it is slightly faster,
that is, it takes less time to encrypt or decrypt a file. This would likely go
without notice, unless you were creating Zip files in which you included many
thousands of files being encrypted while being added.
Security Level
The security of your
data depends not only on the strength of the encryption method but also on the
strength of your password, including factors such as length and composition of
the password. Security also depends on the measures you take to ensure that
your password is not disclosed to unauthorized third parties.
So if u are used more
number with mixed composition, then password cracking get very difficult.
How to Maximize Your Notebook's Battery Charge
Factors that contribute to loss of
battery capacity
v Li-Ion battery cells
suffer gradual, irreversible capacity loss with each discharge charge cycle.
Such aging occurs more rapidly as temperature and discharge loads increase.
v The self-discharge
rate of a Li-Ion battery is higher if the battery is left in an unpowered
notebook.
v During prolonged
storage or non-use, the battery charge will decrease below its recommended
low-voltage level.
v Leaving the battery in a depleted condition for an extended period
accelerates the decrease in FCC. Leaving the battery at a high level of charge
in a hightemperature environment for extended periods (for example, running a
notebook computer in a docking station under a heavy load) also accelerates the
loss of capacity.
v Running high-end
applications using the battery accelerates the loss of capacity. For example,
playing 3D games lowers FCC faster than using word processing applications.
Recommended
battery care practices
v Store Li-Ion
batteries between 20°C and 25°C (68°F and 77°F) with 30% to 50% charge.
v Do not disassemble,
crush, or puncture a battery; do not short the external contacts on a battery;
and, do not dispose of a battery in fire or water.
v Do not leave
batteries exposed to high temperatures for extended periods. Prolonged exposure
to heat (for example, inside a hot car) accelerates the deterioration of Li-Ion
cells.
v Remove the battery if
the notebook will be stored (turned off and not plugged into AC power) for more
than 2 weeks.
v Remove the battery
from the notebook if the notebook will be plugged into AC power continuously
(via a wall adapter or docking station) for more than 2 weeks.
v Use the type of
battery with the highest capacity (Ah) rating if the notebook will run high-end
applications on battery power.
v Calibrate the battery
based on the usage model. Under normal usage, batteries should be calibrated a
minimum of once every 3 months; however, a battery that is rarely discharged
fully should be calibrated about once a month.
v Keep the battery away
from children.
v Use only the battery
provided with the computer or a compatible battery purchased as an accessory.
Tips for
conserving battery power
v You can manually change the power consumption of
your notebook PC and conserve battery power.
v Reduce the number of
open applications . Every application uses memory, and therefore power, even
when the application widow is minimized. Exit any application the is not being used.
v Reduce the brightness
of the screen to the minimum readable level. Use the F7 or F8 keys to adjust
the brightness.
v Remove peripherals
when not in use. External hard drives, CD-ROMs, Zip drives, PC cards, and other
peripheral devices can draw power from
your battery even when they are not in active use. Disconnect them when you are
finished using them.
v Reduce the speed of
your processor. The faster your computer works, the more it uses up the supply
of power. You can extend the charge of your
battery by slowing down your processor's speed. Methods to reduce processor
speed vary from model to model, and your manual should provide instructions for
doing so.
