Floppy disk drive is also known as diskette or FDD. It is a computer disk drive that enables a user to save data on removable diskettes. 

This portable storage device is a rewritable media that can be reused number of times. 

It is made of plastic with magnetic coating on it and round in shape which is covered by square plastic jacket. It is commonly used to move files between different computers. Although, 8″ disk drives made available in 1971 were the first real disk drives, the first widely used floppy disk drives were the 4″, 5 1/4″ floppy disk drives, which were later replaced with 3 1/2″ floppy disk drives. 

However, today these drives are being replaced with CD-R and other writable disc drives and flash drives. 

Advantages of a Floppy Disk 

1. Small and light weighted. 

2. Inexpensive and reusable. 

3. Information is retrieved or accessed only sequentially. 

Disadvantages of a Floppy Disk

1. Can easily be broken or damaged and not much reliable. 

2. Quite slow to access and retrieve data. 

3.  Easily affected by heat

True 

Its coding system contains 14 characters (4 special symbols and 10 decimal digits).

False 

They are high level languages such as C.

MICR stands for Magnetic Ink Character Recognition.

It is a characters recognition technology that can read human unreadable characters that are printed using a special magnetic ink. It is mostly used in banks to facilitate the processing of cheques. 

Advantages 

Advantages of MICR are as follows: 

1. It decreases the margin of errors. 

2. Provides high security. 

Disadvantages 

Disadvantages of MICR are as follows: 

1. Time consuming standards. 

2. The number of characters that can be recorded with present techniques is very limited.

It is a computerised system used to store and retrieve information and conduct transactions related to air travel, hotels, car rental or other activities. 

It is an application software which is commonly seen at railway reservation offices, this software helps the concerned department to automatically check the availability of the seats or berths of any train and on any particular date with an incomparable speed.

 In a few species lose viability within a fewmonths ,live for several years.

1. The first generation languages or 1GLs are low level languages like machine language. 

It is the only language understood by the computers. Sometimes, it referred to as machine code or object code or binary language. It is a collection of binary digits (0 or 1) or bits that the computer reads and interprets. 

2. The second generation languages or 2GLs are also low level languages that generally consist of assembly language. 

It is a low level programming language, which is used as an interface with computer hardwares. It uses structured commands as substitutions for numbers, allowing humans to read the code easier than looking at binary codes. 

3. The third generation languages or 3GLs are high level languages such as C. It is an advanced computer programming language that is not limited to one computer, designed for a specific job and is easier to understand. The main advantage of high level languages over low level languages is that they are easier to read, write and understand, e.g. BASIC, C, FORTRAN, Java and Pascal. 

4. The fourth generation languages or 4GLs are the languages that consists of statements similar to the statements of human language. 4GLs are commonly used in database programming and scripting programming. 

5. The fifth generation languages or 5GLs are programming languages that contains visual tools, which helps to develop a program. A good example of 5GLS is Visual Basic.

The British made number of changes in the existing system to increase the revenue.

1. The payment of revenue was made compulsory in cash and within the prescribed time limit. 

2. Land was confiscated if the revenue was not paid in time. 

3. The land revenue collection differed from place to place which resulted in the exploitation of the farmers. 

4. Farmers were forced to sell their produce to the merchants and middlemen at a low price in order to pay revenue. 

5. Farmers mortgaged land to pay tax and became indebted to moneylenders.

In this way, the farmers became bankrupt in India.

Correct option is (d) Mumbai

1. The British government levied heavy duty on the goods exported from India to England. 

2. The goods imported from England were produced in factories on a large scale and at minimum cost. 

3. The duty levied on them by British was far too less. 

4. So, these goods were cheap as compared to traditional goods. 

5. The Indian artisans found it difficult to compete with low priced British goods. 

6. Eventually, this led to closing down of traditional industries in India.

(i) Too expensive 

(ii) Conventional breeding procedure do not ensure increased production.

Average revenue can be obtained by dividing the total revenue by the number of units produced and sold.

Total revenue means the total sales value of a firm. It can be calculated by multiplying the total sales quantity with the charged price.
TR = Q × P, Where Q = quantity of sale and P = price.
