Answer:
These all are constructors.
<u>CONS</u>
(CONS A B)
makes a pair like this: (A . B)
In other words, A is the CAR of the pair; B is the CDR of the pair.
For example:
(CONS 4 5) ==> (4 . 5)
(CONS 4 '(5 6)) ==> (4 5 6)
[The pair (4 . (5 6)) is the same thing as (4 5 6)].
<u>APPEND </u>
(APPEND A B)
makes a new list by replacing the final nil in A with the list B. A and
B must be proper lists.
For example:
(APPEND '(4) '(5 6)) ==> (4 5 6)
This takes any amount of number and put in this order
<u>LIST </u>
In this ,it will return a list whose elements are value of arguments in the order as it appeared in the LIST.It can take any amount of parameters
For example,
(LIST 4) ==> (4)
(LIST 4 5) ==> (4 5)
(LIST 4 5 '(6 7)) ==> (4 5 (6 7))
(LIST (+ 5 6)(* 5 6)) ==> (8 9)
C- World Wide Web - It has all web pages and files delivered by web servers
Answer:
Augmented Reality
Explanation:
<em>Augmented reality</em> enhances the real-world environment through images, sound, and text. Augmented reality is quite different from Virtual reality, because, virtual reality involves the interaction with the computer-generated environment while, Augmented reality models the real-world environment and enhances the results.
Even though it is considered by some as a futuristic technology, MIT Media Lab, particularly the Fluid Interfaces Group in 2009 introduced SixthSense, a device that projects images that can be manipulated using the fingers. Google also introduced the Google Glass in 2013 but pulled back in 2015, it projects images and videos on the user's lens and responds to voice command.
Augmented reality is gradually becoming part of our lives as it is being integrated into mobile devices and equipment.
In conclusion, Augmented Reality gives users the privilege to view the physical world with layers of computer-generated information.
