Personal
Computer
A personal computer is a
general-purpose computer whose size, capabilities, and original sale price make
it useful for individuals, and is intended to be operated directly by an end-
user with no intervening computer time-sharing models that allowed larger, more
expensive minicomputer and mainframe systems to be used
by many people, usually at the same time.
Software applications for most
personal computers include, but are not limited to, word processing, spreadsheets,databases,
webbrowsers and e-mail clients, digital
media playback, games and many
personal productivityand special-purpose software applications.Modern personal
computers often have connections to the Internet, allowing access to the World
Wide Web and a wide range of other resources. Personal computers may be
connected to a local area network(LAN), either by a cable or a wireless
connection. A personal computer may be a laptop computer or a desktop computer
running an operating system such as Windows, Linux (and the various operating
systems based on it), or Macintosh OS.
Early computer owners usually had
to write their own programs to do anything useful with the machines, which even
did not include an operating system. The very earliest microcomputers, equipped
with a front panel,required hand-loading of a bootstrap program to load
programs from external storage (paper tape, cassettes, or eventually
diskettes). Before very long , automatic booting from permanent read-only
memory became universal. Today's users have access to a wide range of
commercial software, freeware and free and open-source software, which are
provided in ready-to-run or ready-to-compile form. Software for personal
computers, such as applications and video games, are typically developed and
distributed independently from the hardware or OS manufacturers, whereas
software for many mobile phones and other portable systems is approved and
distributed through a centralized
online store.
Since the early 1990s, Microsoft
operating systems and Intel hardware dominated much of the personal computer
market, first with MS-DOS and then with Windows. Popular alternatives to
Microsoft's Windows operating systems include Apple's OS X and free open-source
Unix- like operating systems such as Linux and
BSD. AMD provides the major
alternative to Intel's processors. ARM architecture processors now outnumber Intel's
(and compatibles) in smart phones and tablets , that are also personal
computers, outnumbering the traditional kind.
WORKING
Step1: user enters
the password, if password entered is correct then the system starts else he is
prompted to reenter the password.
Step2: If sensor sense
any change or sense any motion, then an intrusion is detected. Else there is no
intrusion.
Step3: If intrusion is
detected, then relay triggered, stepper motor rotates the camera, it start
recording and an email is sent to user
ADVANTAGES
Invisible Eye Security system
solves many of the problems faced by the multiple camera based security system
at an easily affordable cost.
The biggest advantage is that we
can avoid having to wade through hours of footage of empty rooms.
One can also avoid having to install multiple
cameras to cover a single room.
DIS ADVANTAGES
we have to deactivate the system
while your shop is open
If the owner is out of network then message will not
be sent.
APPLICATIONS
Use for home security systems.
Office security system
Bank security system
CONCLUSION
It is very secure security system
as compare to present security system.
it solves many of the problems
faced by the multiple Camera based security system.so we can use Invisible eyes
instead of present security system.
