Disable F8 Button

For those who wish to Disable the F8 key during the boot process, here's one
option. During the initial boot sequence, it is possible to block all keystroke
until the "start menu" process finishes. It is important to realize that not
only "F8" will be blocked, but also all "multiple boot" option will become
impossible.
If the above statement does not represent a problem, then follow this procedure
with EXTREME precaution:

a) In a command shell (CMD), remove all attributes of C:\NTLDR with the command:

attrib -r -a -s -h c:\ntldr

b) Edit C:\NTLDR, line 760 (in hex), using "HDD HEX EDITOR" (freeware) :

replace:

7f 66 53 e8 1f 1c b8 00 01 cd 16 0f 85 09 00 66

with the new end values:

7f 66 53 e8 1f 1c b8 00 01 cd 16 90 90 90 00 66

and save the corrected NTLDR

c) In a command shell (CMD), re-install all attributes of C:\NTLDR with the
command:

attrib +r +a +s +h c:\ntldr

Nero-7 [Faster Startup]

Faster start-up

type in "services.msc" at a command prompt and press [enter].

next look for "IMAPI CD-Burning COM Services" in the right and pane and double-click on it. In the start-up type dropdown box, select Disable. Remember that you have to disable it-even the “Manual” option will not help. You should now notice the different in start-up speed of Nero.

American Mega Trands (AMI)

AMI is the biggest manufactures of BIOS firmware for major motherboard manufactures.

Founded by two Indians who were social entrepreneurs. AMI started off to be manufacturer of complete motherboards, but couldn’t survive the competition from the original Taiwan-based manufactures; and so made BIOS firmware their riche market AMIBIOS one of the company’s product is the most used BIOS firmware in motherboards. Initially, the firmware had wired problem; it would play the Happy Birth Day tune each time a PC booted up. This was solved with a organ free firm-ware upgrade. In 1994, AMI released an update for AMIBIOS called AMI Win BIOS. It had a graphical user interface setup screen that resembled Windows; it receive mixed response from its users due to the novely of the concept.

AMI developed AMI Diag, a PC diagnostic utility sold only to original equipment manufactures (OEMs) to help them spot problems while booting.

AMI later diversified into the domain of mobile applications, online data storage (through “Star Trands”) and remote management (“Mega Rac”) but BIOS firmware remains its primary product range.

Analog Computers

    Analog Computer     

           Analog computer were pretty  famous in 40's war-II, Vietnam war even used in major wars such as world war and Korean war, but are now technically. An analog computer accepts inputs/physical quantities that very according to time such as electrical potential, fluid pressure or mechanical motion and applies to compute the operation of addition and subtraction, setting up an analog computer requires plenty of effort, it's usually set with initial conditions/values which can later be changed.

      The earliest analog computer was built in 1893 by Lord Kelvin some major milestones in its development process were.

     Inclusion of the harmonic analyzer in 1898, it had 80 components and was capable of generating sinusoidal  motion.

     Invention of the differential analyzer in 1930, it used mechanical integrators to solve differential equations and was a major break through for the technology.

     Analog systems were mainly used in simulating dynamic environments such as aircraft and nuclear process. But the analog computer locked the ability to store large quantities of data unlike their modern day digital co-counterpart. Also performing accurate arithmetic and integral operations in analog computers required costly hardware, which was infeasible.
