Answer:
Language is made up of syntactic norms and semantics since it is a resource which we use to develop computer programs and solve problems. The package, on the other hand, is a type of folder since it is a collections of linked and pre-defined classes. Furthermore, a package is designed for a certain set of tasks which has a limited computational capability. So, language has a set of rules and syntax for creating data encapsulation, whereas package has a chain of conditions for building menu action programs and applications.

Check the explanation
Explanation:
When there is a need to initialize a lot of element of same data types,tht time we use arrays.
We have to use array whenever it involves simple programs and cases,
dx:saving age of 100 childrans of sametype
When all the ele,ents are of different data type,we hould not use arrays,even when we initialize at runtime,we dont need arrays.i.e when size is not fixed
Linked list can be used instead of arrays
ArrayList:It provides methods for creating, searching, manipulating, and sorting arrays, thereby serving as the base class for all arrays in the common language runtime.
Advantages:
Readymade properties availaible ,so lot of writing and remembering the code can be avoided.
Provide the reference for other arrays
Helps in faster execution
The way that adding descriptive headers to columns of data in a spreadsheet improve the spreadsheet is that; It adds context to the data.
- Usually in spreadsheets in Microsoft Excel, we could just naturally use letters like A, B or C or even numbers like 1, 2, or 3 as title headers for columns. However, sometimes it becomes necessary to use descriptive headers. This is because the person reading it may not be able to easily comprehend the details or numbers in that particular column.
- Thus, in order to add more context to the data in the column of the spreadsheet and improve understanding of context using descriptive headers is very useful.

Answer:
a) only one digit changes as the number increases.
Explanation:
Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)
consider the 4 bit representation of Binary coded decimal and RB codes
Decimal | Binary code | Reflected binary (RB) code
0 0000 0000
1 0001 0001
2 0010 0011
3 0011 0010
4 0100 0110
5 0101 0111
As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.
But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.
The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.
The RB code is widely used in linear and rotary encoders, error correction and digital logic design.
Answer:
Option (a) is the correct answer of this question.
Explanation:
E-Learning means that Electronic Learning. It covers a broad spectrum of applications, including online and computer-based training (CBT) and public networks.E-Learning is learning to use new technology to navigate curricula beyond a conventional classroom is known as Electronic learning.
- E-learning is a nurturing environment that allows use of information and communication technologies (ICTs) as a pedagogical tool.
- E-learning not a program distributed over a Disc or CD-ROM, a video tape or a TV channel.
<u>There are two types of E-learning are known as</u>:-
- Synchronous E-learning.
- Asynchronous E-learning
