Three processes share four resource units that can be reserved and released only one at a time. Each process needs a maximum of two units. Show that a deadlock cannot occur.

Answers

Answer 1

A deadlock cannot occur because each process only needs a maximum of two resource units, and there are four resource units that can be reserved and released one at a time.

What is deadlock?
Any circumstance in which no member of a group of entities can move forward because each one is waiting for another member, including itself, to act, such as sending a message or, more frequently, releasing a lock, is referred to as a deadlock in concurrent computing. Due to the frequent usage of hardware or software locks in multiprocessing, parallel computing, or distributed systems to manage shared resources to implement process synchronisation, deadlocks are a typical issue in these environments. When a process or thread enters a waiting state due to a system resource being held by some other process that also is waiting for another resource which is being held by some other waiting process, a deadlock occurs in the operating system.

What is troubleshooting?
Troubleshooting
is a type of problem resolution that is frequently used to fix broken components or operations on a machine or a system. In order to address an issue and get the product or process back in operation, a logical, methodical search for the problem's source is required. It takes troubleshooting to find the symptoms. Eliminating potential sources of a problem allows you to determine the most likely cause. Troubleshooting also involves verification that the fix really returns the process or product to functioning order. Troubleshooting is, generally speaking, the detection or diagnosis of "trouble" in the management flow of the a system brought on by some sort of breakdown. Troubleshooting is the act of identifying and resolving the sources of these symptoms, which are initially stated as signs of malfunction.

What is program?
A computer utilises a set of instructions called a program to carry out a particular task. A program is like the recipe for a computer, to use an analogy. It includes a list of components (called variables, which can stand for text, graphics, or numeric data) and a list of instructions (called statements), which instruct the computer on how to carry out a certain activity. Specific programming languages, such C++, Python, and Ruby, are used to construct program. These are high level, writable, and readable programming languages. The computer system's compilers, interpreters, or assemblers subsequently convert these languages into low level machine languages. Technically, a human could write assembly language, a kind of low level language that really is one step above machine language. The register window is used for displaying the values of the registers. The memory window is used for displaying the contents of the memory. The cross-reference window is used for displaying the data and code cross-references. The data and code cross-references are used for finding the locations of the data and code that are referenced by the program.

Answers

You need to connect your doorbell to the electricity in a battery. You should select a material that will accept the flow of electrons.

You can think of a circuit as a loop. In order for electric current to flow through the loop, the \sloop must not contain breaks. In other words, the circuit must \sbe closed. An open circuit has one or more breaks. Most \scircuits have an energy source, wires, a load, and a switch. As \smentioned, energy sources for circuits include generators and \sbatteries.

Machines that generate electricity from mechanical energy are called generators. In this lesson, we’ll focus on batteries. Inside a battery, two kinds of metals build up opposite charges. Negative charges build up on one end of the battery. Positive \scharges build up on the other end of the battery. This is why batteries are marked with \spositive sign (+) and a negative sign (–).

1) why do local variables lose their values between calls to the function in which they are defined.

Answers

Because they are created in memory when the function begins execution and destroyed when the function ends, thus local variables will lose their values between calls in the function in which they are already defined.

What is a Variable in the programming?

Variables are names given to locations in the computer memory, where data can be stored in a program. Based on the values assigned to the variables, this data can be known or unknown.

Variables can also be thought of as 'containers,' as they can hold more than one value. Their sole purpose is to store data and label it in memory, which can then be accessed throughout the program as needed.

In C programming, creating variables is also known as declaring variables. Variables are created in a variety of ways depending on the programming language.

why does discharge in a stream usually increase downstream? group of answer choices because the volume of water in the stream increases with distance from the source because stream velocities increase with distance from the source because the stream is deeper downstream because the frictional resistance decreases downstream

Answers

Discharge in a stream usually increase downstream because the volume of water in the stream increases with distance from the source and the main reason of flowing downward is phenomena of gravity and also because stream velocities increase with distance from the source.

What is a Stream and How does it works?

A stream is a body of water that flows on the surface of the Earth. The terms stream and river are frequently used interchangeably, though rivers typically describe larger streams.

Streams require gravity and water to exist. When precipitation falls on the ground, some of it trickles into groundwater, but the majority of it runs downhill as runoff and collects in streams. A watershed, also known as a drainage basin, is the area where water is collected for a stream. Smaller streams frequently merge to form larger streams as they flow downhill. These smaller streams are referred to as tributaries.

Hong Kong currently dicard approximately 10,000 tonne per day (tpd) of MSW. The HKSAR Government decided to build a modern wate-to-energy incinerator for MSW treatment. The incinerator ha a capacity of 4,000 tpd. Given that the LHV of the MSW in Hong Kong i about 13,000 kJ/kg and the efficiency of the incinerator for electricity generation i 16%. Etimate the electricity production from the incinerator per day at it full capacity

Answers

The electricity production from the incinerator per day at it full capacity is 1950 MWh / day

Q = 10, 000 tonnes / day

Capacity of incinerator = 3000 tonnes / day

I tonne = looo kg

Low Heating Value of MSW = LHV = 13, 600 K J / kg

Efficiency of incinerator for electricity generation = 0 .18

Electricity production from incinerator per day at full capacity

LHV x full capacity x efficiency

= 13, 000 KJ/kg x /3000 x 1000 kg* 0 . 18 *1 MWh/3.6 * 106 KJ

1MWh = 3600000 KJ=> IKJ =1 MWh/3. 6 * 10⁶

electricity production = 1950 MWh / day

Electricity generation is the process of producing electricity from main energy sources. Prior to delivery to end consumers or storage, it is the phase for utilities in the electric power sector. Electricity must be "made" because it is not naturally occurring.
