Is a replay attack a type of man in the middle attack? This is carried out either by the originator or by an adversary who intercepts the data and re-transmits it, possibly as part of a spoofing attack by IP packet substitution. This is one of the lower-tier versions of a man-in-the-middle attack. Replay attacks […]
How do you calculate module efficiency?
How do you calculate module efficiency? To calculate the solar panel efficiency, you need to divide the Wattage per unit area (Pmax/total area in sq. m.) of the solar module by the STC Irradiance value (1000W/sq. m.). What does module efficiency mean? The Module Efficiency rating on your solar panel’s spec sheet measures the percentage […]
What is the difference between brittle fracture and ductile fracture?
What is the difference between brittle fracture and ductile fracture? Brittle fracture means fracture of material without plastic deformation or with very small plastic deformation before fracture. Ductile fracture means fracture of material with large plastic deformation before fracture. How do ductile and brittle materials differ in their behavior in the compression test? DUCTILE MATERIAL […]
What is assembly language and machine language?
What is assembly language and machine language? Difference Between Assembly Language and Machine Language. Machine language is a language that has a binary form. It can be directly executed by a computer. While an assembly language is a low-level programming language that requires software called an assembler to convert it into machine code. Which language […]
Are Christmas lights wired in series or parallel?
Are Christmas lights wired in series or parallel? Christmas lights are wired as a “series” of lights along a single electrical path. That means that the first bulb must past electricity to the next, sequentially, from first to last in the series for ANY of them to light up. How do you test 3 wire […]
Which of the following metals would typically be used in die casting?
Which of the following metals would typically be used in die casting? The most commonly used die-cast metals are as follows: Zinc. Aluminum. Magnesium. What is made from die casting? In fact, die-cast parts can be found in many things; you are probably just unaware that they are made from die-cast metal. Locks and gears […]
What causes no spark from coil?
What causes no spark from coil? Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap. Can a bad ignition coil cause no spark? A Bad […]
What are the three 3 basic steps of the photolithography process?
What are the three 3 basic steps of the photolithography process? Photolithography uses three basic process steps to transfer a pattern from a mask to a wafer: coat, develop, expose. The pattern is transferred into the wafer’s surface layer during a subsequent process. Which of the following best describes the photolithography process? Which of the […]
What effects do tariffs have on the economy?
What effects do tariffs have on the economy? Tariffs damage economic well-being and lead to a net loss in production and jobs and lower levels of income. Tariffs also tend to be regressive, burdening lower-income consumers the most. What are the effects of a tariff on a good? Trade barriers such as tariffs raise prices […]
