What is collision resistance property of a hash function ?

Collision resistance is a property of cryptographic hash functions: a hash function is collision resistant if it is hard to find two inputs that hash to the same output. In other words, consider a function fx which generates the same result y for separate inputs a and b. That is, fa = y = fb. It is then said that fx produces a hash collision. Collision resistance attempts to prevent an attacker from

What is abohm ?

hi!The abohm symbolized ab W is the unit of electromagnetic resistance in the cgs centimeter/gram/second system of units. It is equivalent to 10 -9 ohm s. When a current of one abampere 1 abA flows through a resistance of 1 ab W , the resulting potential difference across the component is one abvolt 1 abV.The abohm is an extremely small unit of resistance. In fact, an object with a resistance of 1 ab

The PIN diode based on - a Nonlinear resistance b Nonlinear reactance c Negative resistance d Controllable impedence

well;The PIN diode based on c Negative resistance...Nawaraj the silicon pin-diode in which the width of i-region is from 6 to 12 times the diffusion length shows negative resistance in the forward direction.So the answer is negative resistance...........The silicon pin-diode in which the width of i-region is from 6 to 12 times the diffusion length shows negative resistance in the forward direction

How does touch-screen work?

http://www.touchscreens.com/intro-a natomy.html...There are three basic systems that are used -Resistive The resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor

What does "resistant up to 10 meters" inscribed on water resistant watches mean?

IIt is usually accompanied by an indication of the static test pressure that a

What happens when DC supply is connected to AC "TRIAC"?Complete process.

at the firing point, but the...n increases continuously to a maximum and drops to zero. Different resistance and inductance values have different time profile of the current because of having different time constant, even with identical gate angles. The time profiles for purely resistive and purely inductive load represent limitingcases. Because of the storage capacity of the inductance, the direct current

what is impedance?which r the electronics devices in which it is supposed to be high and low?what is unit of impedance?

://home.flash.net/rc ollier/impedance.htm...Impedance is the generalization of the concept of resistance from DC to AC. That is, its a way to represent how much current will flow with a specified AC voltage across the impedance they cause no heat to be dissipated as a result of their current limiting. In fact, the impedance of inductors and capacitors is so different from a resistance that its given a special name - "

WHat IS the biotechnology future?

The recent emphasis on environmental awareness has challenged scientists to find solutions for better and safer living conditions. The added threat of deadly diseases such as AIDS and resistant emphasis on environmental awareness has challenged scientists to find solutions for better and safer living conditions. The added threat of deadly diseases such as AIDS and resistant strains of tuberculosis

how many printouts will a laser printer yieldbefore which u have to change thte catridge?

as inkjet. Inkjet on the other hand is not very moisture resistant and runs easily if wet. You can get "waterproof" ink jet inks in lexmark and HP.You may find using commercial grade inkjet with water resistant ink and higher qualty inkjet paper would be more marketable and more cost effective in this application. or Im a hp Group technician . i have a idea about printer. the best printer

What does the term PLC stand for?

to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored

What is a touch screen monitor?

There are a number of types of touch screen technology:Resistive A resistive touch screen panel is composed of several layers. The most important are two thin metallic electrically conductive and resistive on force in this model -- between the dividers. A resistive touch panel output can consist of between four and eight wires. The positions of the conductive contacts in resistive layers differ depending

Is it possible for a women to rape a man? And would any man actually resist?

Rape is the act of forcing somebody to have sex with you when the other person does not have an interest. So, rape involves violence and so everyone will resist it unless the person is threat for any resistance. Males too can be raped by women. Generally, the cases of raping school children by women came out in the newspapers, though it is rare. The difference in sex and rape is that, sex is mutually

to main terminal 2 MT2 should test like a diode junction in both directions. MT1 to MT2 and gate to MT1 junctions should read open. For diacs and sidacs, there is no gate terminal - resistance should be infinite in both directions. For more complete testing, see the section: Testing Diacs and Sidacs.Note: Some thyristors will have a low G-K/MT2 resistance but it should not read as a short.The real test
