What is the probability of getting at least one red marble? (The chance of getting at least one red marble, on the other hand, is 3/12 + 3/12 – (3/12 × 2/11), or only 10/22.) What is the probability of selecting a blue marble? 1/5 What is the probability of selecting a green marble? 1/4 […]
What is a deadlock and how can it be avoided?
What is a deadlock and how can it be avoided? In order to avoid deadlock, you have to acquire a lock in the fixed order. Once process1 commits the transaction successfully, it will release the locks on the resources; therefore process 2 will get the required resources in order to complete the transaction successfully without […]

What are the six key elements in organizational design? The six basic elements of organizational structure are: departmentalization, chain of command, span of control, centralization or decentralization, work specialization and the degree of formalization. What are the 4 types of organizational structures? Traditional organizational structures come in four general types – functional, divisional, matrix and […]
What sparked the space race between the United States and the Soviet Union?
What sparked the space race between the United States and the Soviet Union? The Space Race was a 20th-century competition between two Cold War adversaries, the Soviet Union (USSR) and the United States (US), to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following […]
Which way does a capacitor discharge?
Which way does a capacitor discharge? When the capacitor is discharging, the current flows towards the negative plate, and the current flows away from the positive plate, in the opposite direction. Whereas, while the capacitor is charging, the current flows towards the positive plate and away from the negative plate. Which way round do you […]
What is contention period in CSMA CD?
What is contention period in CSMA CD? Contention window: If participants determine that the channel is free, they wait a random amount of time before they start sending. This duration corresponds to the contention window. This time window doubles with each collision and corresponds to the binary exponential backoff (BEB) that is familiar from CSMA/CD. […]
What is a hangover caused by?
What is a hangover caused by? Hangovers are caused by drinking too much alcohol. A single alcoholic drink is enough to trigger a hangover for some people, while others may drink heavily and escape a hangover entirely.

How do you calculate 16 bit checksum?
How do you calculate 16 bit checksum? 1 Answer. To calculate a 16-bit checksum, you process the array in increments of 2, and put one byte into the low-order byte of the value that you’re adding, and the other byte into the high-order byte. There’s no need to use modulus, since unsigned integers implement modular […]
What are the 3 modes of heat transfer?
What are the 3 modes of heat transfer? Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own. What type of heat transfer is air conditioning? In the HVAC and Refrigeration field, convective […]
What are the three major assumptions used in the derivation of the Bernoulli equation?
What are the three major assumptions used in the derivation of the Bernoulli equation? The flow must be steady, i.e. the fluid properties (velocity, density, etc…) at a point cannot change with time. The flow must be incompressible – even though pressure varies, the density must remain constant along a streamline. What are the assumptions […]
