Answer:
Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. Demand is based on needs and wants—a consumer may be able to differentiate between a need and a want, but from an economist’s perspective they are the same thing. Demand is also based on ability to pay. If you cannot pay for it, you have no effective demand.
What a buyer pays for a unit of the specific good or service is called price. The total number of units purchased at that price is called the quantity demanded. A rise in price of a good or service almost always decreases the quantity demanded of that good or service. Conversely, a fall in price will increase the quantity demanded. When the price of a gallon of gasoline goes up, for example, people look for ways to reduce their consumption by combining several errands, commuting by carpool or mass transit, or taking weekend or vacation trips closer to home. Economists call this inverse relationship between price and quantity demanded the law of demand. The law of demand assumes that all other variables that affect demand (to be explained in the next module) are held constant.
The answer for the above question is True.
Yes, Express replaces the request listener feature of node.js.
<h3>What is node.js ? </h3>
- It is known to be JavaScript runtime that is event-driven and asynchronous, making it ideal for creating scalable network applications. In the following "hello world" example, numerous connections can be handled concurrently.
- Every connection triggers the callback, but if nothing has to be done, Node.js will sleep. This contrasts with the concurrency approach that is currently more often used, which makes use of OS threads.
- The utilization of thread-based networking is extremely challenging and wasteful. Node.js users also don't have to worry about deadlocks because there aren't any locks.
- Node.js has almost no functions that conduct I/O directly, therefore the process never blocks until the I/O is carried out using synchronous methods from the standard library.
- Scalable systems can easily be created in Node.js because nothing blocks.
