Least Significant Digit

Consider the number 627. Its MSD is 6

An Internet database is accessible by everyone who has access to a Web site. An intranet database limits access to only people within a given organization. An extranet database limits access to only people within a company and a company's customers and suppliers.

Many businesses still use file processing systems today. This is especially true in the creation of backups for a database system. In addition, if you understand some of the limitations of a file processing system such as program-data dependence, duplication of data, limited data sharing, lengthy development times, and excessive program maintenance, you can try and avoid them as you design and develop a databases.

Databases can support from a single user (personal database) up to supporting the requests of the world (internet database). In between, a database can support a workgroup (a relatively small group of people), department database (a functional unit in an organization such as marketing), or an enterprise database (entire organization).

The statement True

A(10), B(11), C(12), D(13), E(14), F(15)

There are five disadvantages. 

1. Program-data dependence occurs when file descriptions need to be changed in all programs whenever a file description changes. 

2. Duplication of data is storing the data more than one time. 

3. Limited data sharing occurs when the files are private so no one outside of one application can access the data. 

4. Lengthy development times exist because file processing systems takes longer to develop. 

5. Lastly, excessive program maintenance exists since the effort to maintain a program is larger in this environment.

The advantages of object oriented programming:

1. OOP provides a clear modular structure for programs. Large problems can be reduced to smaller and more manageable problems.

2.  In OOP, data can be made private to a class such that only member functions of the class can access the data. This principle of data hiding helps the programmer to build a secure program.

3. Implementation details are hidden from other modules and other modules has a clearly defined interface.

4. It is easy to maintain and modify existing code as new objects can be created with small differences to existing ones.

The disadvantages of object oriented programming:
1. Size:

Object Oriented programs are much larger than other programs. In the early days of computing, space on hard drives, floppy drives and in memory was at a premium. Today we do not have these restrictions.

2. Effort:
Object Oriented programs require a lot of work to create. Specifically, a great deal of planning goes into an object oriented program well before a single piece of code is ever written. Initially, this early effort was felt by many to be a waste of time. In addition, because the programs were larger (see above) coders spent more time actually writing the program.

3. Speed:
Object Oriented programs are slower than other programs, partially because of their size. Other aspects of Object Oriented Programs also demand more system resources, thus slowing the program down.

A candidate key is a column, or set of columns, in a table that can uniquely identifies a tuple and is not null.

Each table may have one or more candidate keys. It is eligible to be a Primary key.

For example: In a table PERSON following are the columns (Aadhar number, PAN, Voter ID card no, Name, Date of birth, Address).

Out of these Aadhar number, PAN, Voter ID card no are the candidate keys.

A(10), B(11), C(12), D(13), E(14), F(15)

If there is no match for the expression with any case group in switch statement, the statements in the default part are executed.

For example:

{

switch(dy)

{

case 6: day = “Saturday”;

break;

case 7: day = “Sunday”;

break;

default: day = “Incorrect Day!

break;

}

System. out. print ln (day);

}

if the value of dy is other that 6 or 7 default statement will be executed.

The database and DBMS software together is called as Database system.

1. Redundancy is controlled. 

2. Unauthorised access is restricted. 

3. Providing multiple user interfaces. 

4. Enforcing integrity constraints. 

5. Providing backup and recovery.

i. Antivirus and Antispyware programs offer real-time protection monitoring your computer for any changes by malware software.

ii. Use strong passwords a combination of alphanumeric and special characters could be used for creating a password that is not so easy to crack or guessed by other users.

iii. Secure transactions because information such as credit card details or personal information is sent over the network.

iv. Use encryption software to protect your data from unauthorized users.

1. Data redundancy and inconsistency. 

2. Difficult in accessing data. 

3. Data isolation. 

4. Data integrity. 

5. Concurrent access is not possible. 

6. Security Problems.

A database management system is a software package with computer programs that controls the creation, maintenance, and use of an integrated collection of data records, files, and other objects. It allows organizations to conveniently develop databases for various applications.

Advantages:

i) Data integrity: means the data is accurate and consistent in the database. It is very important as there are multiple databases in a DBMS so it helps to produce the correct result.

ii) Data sharing: In a database, the users can share the data among themselves. Data can be shared for multiple purposes with the users located at different geographical locations then remote users can also access the database simultaneously.

d) relational operators

! =, <, >,  > = are examples of relational operators.

Exponent and Mantissa

A bit stands for Binary digit. That means either 0 or 1.

A computer has no IQ

1 KB is 2²⁰ bytes

The sort method of Array class is used to arrange the Array of integers in ascending order.

+60 = 00111100 

Change all 1 to 0 and all 0 to 1 to get the 1’s complement. 

-60 is in 1’s complement is 11000011

Change all 1 to 0 and all 0 to 1 to get the 1’s complement. 

– 60 is in 1’s complement is 11000011

Convert all the numbers into a common base i.e. to decimal 

a) (1101)₂ =  1 x 2³ + 1 x 2² + 0 x 2¹ + 1 x 2⁰

= 8 + 4 + 0 + 1

= (13)₁₀

b) (A)₁₆  = (10)₁₀

c) (13)₈  = 1 x 8¹ + 1 x 8⁰

= 8 + 3

= (11)₁₀

d) (15)₁₀  Here (A)₁₆ is the smallest number.

Correct option: c. To start an online coding course for 3 months

It is 1 because In SMR if the number is negative then the MSB is 1.

Webinars are real time online lectures, where users participate in the lecture, may ask questions, and get their queries answered.

it is like ASCII Code. By using ASCII, we can represent limited, number of characters. But using Unicode we can represent all of the characters used in the written languages of the world. 

Eg:- Malayalam, Hindi, Sanskrit …….

It is like ASCII Code. By using ASCII, we can represent limited number of characters. But using Unicode we can represent all of the characters used in the written languages of the world. 

eg: Malayalam, Hindi, Sanskrit .

The limitations to store more characters is solved by the introduction of Unicode. It uses 16 bits so 2¹⁶ =65536 characters(i.e, world’s all written language characters) can store by using this.

71.24 = 7 × 8¹ + 1 × 8⁰ + 2 × 8^-1 + 4 × 8^-2 

= 56 + 1 + 2/8 + 4/82 

= 57 + 0.25 + 0.0625 (71.24)₈

(71.24)₈ = (57.3125)₁₀

Yes, doctor has advised me to eat sprouts because they are very nutritious.

71.24 = 7 x 8¹ + 1 x 8⁰ + 2 x 8^-1 + 4 x 8^-2

= 56 + 1 + 2/8 + 4/28

= 51 + 0.25 + 0.0625

(71.24)₈ = (57.3125)₁₀

Amines are organic compounds which contain and are often actually based on one or more atoms of nitrogen. Structurally amines resemble ammonia in that the nitrogen can bond up to three hydrogens, but amines also have additional properties based on their carbon connectivity.

Silicones act as excellent insulators for electric motors.
Straight chain polymers of silicone are silicone fluids. They are used is water proofing textiles as lubricants and as polish.
Silicone rubber retain their elasticity and resist chemical attack.
Cross linked polymer of silicones are used as non-stick coating for pans and in paints and varnish.
Silicone coating are highly stable and non-volatile even on heating. Hence used for high temperature oil bath, high vacuum pump etc.

Answer: equal to that on the Fahrenheit scale.

Correct option is C) with

According to James Allen, generally speaking, the secret of health is faith and purity. The secret of health in particular is the harmonious mind.

Sickness is the result of our own error. Angry, worry, jealousy, greed and such other feelings sow the seeds of disease in our mind. In order to be healthy, we should keep our mind free from these feelings. Jealousies, suspicions, worries, hatreds and selfishness causes disease of stomach, nerve and pain of joins. On the other hand, if we have joyful and loving thoughts and good will, we shall need no medicine.

Work or even overwork does not destroy one’s health. Bad health is often the result of foolishly wasted energy. Work, mental or physical is always health giving. What is needed is to work without being anxious or excited or worried over needless detail. The secret of health is thus a pure heart and a well- ordered mind.

Strong faith and purity are the necessities for health success and power.

Answer: Larger the amount of magnetic flux linked with a circuit, greater is the e.m.f. induced in it.

Reverse transcription begins when the viral particle enters the cytoplasm of a target cell. The viral RNA genome enters the cytoplasm as part of a nucleoprotein complex that has not been well characterized. The process of reverse transcription generates, in the cytoplasm, a linear DNA duplex via an intricate series of steps. This DNA is colinear with its RNA template, but it contains terminal duplications known as the long terminal repeats (LTRs) that are not present in viral RNA
