Answer:
An application programming interface (API) is the code the CPU recognizes to perform a procedure in an application.
Explanation:
An application programming interface (API) is the code the CPU recognizes to perform a procedure in an application. API allows an application to communicate with another application, or an operating system, database, network, etc.
An Application Programming Interface (API) creates a consideration for a problem and specifies how clients should interact with software components that implement a solution to that problem.
More recently, API has been used to refer to a specific type of interface between a client and a server, which has been described as a “contract” between both - such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.This is a specialized form of API, defined as a Web API.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Answer:
A communication barrier is anything that prevents us from receiving and understanding the messages others use to convey their information, ideas and thoughts.They can interfere with or block the message you are trying to send.
Yes you do have to program it first.
Assembly language, a.k.a. machine language.
