ENGLISH- REVISION QUESTION BANK

1. Read the following passage carefully.
Earthquakes can cause the ground to shake and crack apart. Earthquakes can be very powerful, and if they occur in or near areas where people live, they can make buildings collapse, bridges sway, and roads buckle. But not all earthquakes are powerful enough to cause damage. In fact, earthquakes are happening all the time, on land as well as in the oceans. Most of the earthquakes are so mild that people don’t even feel them. An earthquake is the sudden movement of the earth’s crust. Earthquakes occur along fault lines, cracks in the earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping or colliding. As the plates grind together, they get stuck and the pressure builds up. Finally, the pressure between the plates is so great that they break loose. Depending on how much pressure has built up, the ground may tremble slightly or shake
forcefully. Scientists describe the intensity of an earthquake using the Richter scale. It measures earthquakes on a scale of 1 to 10. People barely feel a magnitude 3 earthquake, and windows might rattle at magnitude 4.A magnitude 6 earthquake is considered major, causing houses to move and chimneys to fall. The most severe earthquake recorded had a magnitude of 9.5.

1.1 On the basis of your reading of the above passage, complete the following sentences with appropriate words/phrases :
a) Earthquakes can make buildings collapse if
_____________________________.
b) Not all earthquakes cause ___________________.
c) Earthquakes occur on ___________________ as well as in oceans.
d) The sudden movement of the earth’s crust is an
_______________________.
e) Earthquakes occur where the tectonic plates are
_______________________.
f) The pressure builds up when _________________________________.
g) An earthquake’s intensity is measured using an instrument called
________________________________.
h) A magnitude 6 earthquake causes
___________________________________.
2. Read the following passage carefully.
Bees are flying insects that feed on
nectar and pollen. They are usually
yellow and black and covered in
fuzzy hair that makes collecting
pollen easier. A bee’s body is similar
to that of other insects – for instance,
an ant – with three major sections:
the head, the middle section called
the thorax and the last section called
the abdomen.
The head of a bee has five eyes for seeing and two antennae for
touching and smelling. Two sets of wings and three sets of legs can be
found on a bee’s thorax. Depending on the type of bee, the last set of
legs might have little sacs that store the pollen that the bee has
collected from flowers. Many types of bees have stingers. The bee
stinger is the most feared part of a bee, and for good reason. Filled with
poison, the stinger is a bee’s protection from danger. The stingers are
around 12 millimeters long. There are over 20,000 known bee species in
the world. The best known is probably the honeybee.
Honeybees live in beehives, which have a distinct order that helps
things run smoothly. At the bottom of the totem pole are the workers.
Workers are young female bees. Some of their main duties include
going out to find food (nectar and pollen), building the hive, and
keeping it clean. Honeybees will travel up to eight miles if necessary to
find nectar and pollen to bring back to the hive. Worker bees are
actually the only bees that ever do any stinging. When this does
happen, it is usually because they are trying to protect their hive from
harm. A bee rarely stings when it is away from the hive, but it might
sting if it senses danger. The lifespan of a worker bee is anywhere from 4
to 9 months.
The queen honeybee is the biggest bee in the hive. There is usually only
one per hive, and her job is to grow the family by laying eggs that will
become the next generation of honeybees. She lays over a thousand
eggs per day and can live anywhere from 3 to 5 years. When the time
comes for a new queen to take over, some larvae are placed in
special chambers to grow queen bees. After they hatch, they are
fattened up with royal jelly, a nutritious substance that worker bees
secrete. It usually takes about two weeks for a newly hatched female
bee to grow into a queen bee. The first female bee to become a
queen bee kills the other potential queen bees.
Male honeybees are called drones. They don’t have stingers, and they
don’t collect nectar or pollen. Their only purpose is to mate with the
queen. Several hundred drones can live in a hive at one time. As the
winter months approach, the males are kicked out of the hive in order
to make it easier for the queen and her workers to survive. Food needs
to be saved as there are fewer flowers to collect pollen and nectar
from. Less food means the drones are the first ones to go!

Computer Chap 7 - Computer Virus

7 Computer Virus

Que 1.  Wht is a Computer Virus?
Ans :-    A computer virus  is a program which is loaded onto your computer without your knowledge and cause interferences  with computer operation.

Que 2.  What are the symptoms 0f a Computer Virus? Or
              How do you find out if your computer is infected with a virus?
Ans :-   if your computer is infected with a virus it shows the following signs:
ÒFunctions slower than normal.
ÒResponds slowly and freezes often.
ÒFiles or folders gets deleted or changed without the user knowledge.
ÒSee uncommon error messages, distorted menus, and dialog boxes.
ÒNotice applications fail to work correctly.
ÒHard disk may get erased.
ÒFiles become bigger in size, thereby reducing disk space

Que 3.  Explain different types of computer viruses in detail:
Ans:- Computer viruses can be classified into different types based on their origin, techniques, the types of files they infect, the kind of damage they cause and the platform they attack.
The main type of computer viruses are:
1) File Virus :-   File virus infects program files such as .exe. .com etc. Once this virus gets active in the memory, it tries to infect all the programs that are further loaded into the memory.
2) Macro Virus :- It is a type of virus which infects the Microsoft Word and other applications. Once infected repairing these files become very difficult.
3) Boot sector or Master Boot Record(MBR) Virus:- This kind of virus infects the first sector of a storage device which is used for loading the operating system. It becomes active as soon as the computer is started.
4) Multipartite Virus :- It is a combination of Boot and Program/file viruses. It infects program files and when an infected program is executed, the virus infects the boot record. When the computer is booted the next time the virus from the boot record loads into the memory and then it starts infecting other program files on the disk as well.
5) Polymorphic Viruses :- A polymorphic virus is a self-encrypted virus designed to avoid detection by a scanner. Upon infection, the polymorphic virus duplicates itself by creating usable, albeit slightly modified, copies of itself.
6) Worms :- These kind of virus makes copies of itself and spread to other computer through network thereby showing down the traffic on the network. Able to  spread very quickly makes them really damaging. For ex. Blaster, Code Red and Sasser.
7) Trojan Horse :- Not considered as virus as it cannot replicate itself. A Trojan horse is a coded program which makes the existence of a virus by making its appearance look normal while containing malicious utilities transparent to the user. It may creates breaks in the security of the system by leaking information through a backdoor. Generally used for online  fraud and theft of confidential and personal data. For ex.  ‘Waterfall.scr’, ‘Beast’

Que 4.  How to protect your computer from viruses?
ÒUpload and use antivirus software
ÒBe aware of the e-mails and attachments you open
ÒCheck for updates on antivirus software regularly
ÒMake sure antivirus software is installed correctly
ÒEnable the Macro Virus Protection in MS Office application and do not run macros unless you know what they do.
ÒUse email programs that have built in spam filters.
ÒAvoid installing programs from unknown sources.
ÒAlways keep a regular back up of the your data to avoid any loss  

Que 5.  What is the use of Anti-Viruses Software?
Ans:- Anti-Virus Software scans files on your computer and the computer memory for known viruses.

Que 5.  How does  Anti-Viruses Software work?
Ans:- if the Anti-Virus program finds a virus, it may attempt to
§  Remove the virus(clean the file),
§  Quarantine the files(move the file to a safe area so that it cannot harm your system),
§  Delete the file.
Since new viruses are being released continually, the Anti-virus software needs to updated on a regular basis to that you have the least definitions installed in your computer.

Que 6.  Give few examples of Anti-virus Software.
§  AVG
§  BitDefemder
§  Kaspersky
§  AcAfee
§  Norton
§  Quick Heal

Que 7. Fill in the Blanks.
1) A Boot Sector virus infects the first sector of a storage device which is used for loading OS programs.
2) ‘Waterfall.scr’ is an example of a Trojan horse.
3)  Anti-virus software needs to be updated to keep track of latest viruses.
4) Quarantine is a term used to move an infected file to a safe area to that it cannot harm your system.
5) ‘Code Red’ and ‘Sasser’ are example of worms.
6) The Melissa virus or (1999) forced MS to temporarily shut down its email servers.
7) The I Love You virus(2000) came as an email attachment which on double clicking sent copies of it to everyone on the victim’s address book.
8) Code Red made headlines(2011) when it slowed down internet traffic by replicating itself.

Computer - Chap 5 -Introduction to 'C' Language

1.     Errors are mistakes in program, which     are traced by the compiler.
Que 13.Explain errors of C programs in detail.
Ans. Errors are mistakes in program, which are traced by the compiler while compilation. A program can only execute when all the errors are corrected.
 Types of errors:
1)                Logical errors – occur when the result we get is not correct because of the incorrect code logic.
2)                Syntax : occur when the grammar of the C language is not used properly.

For ex
1.     Typing Printf or print instead of  printf.
2.     Forgetting a semicolon (;) at the end of an executable C statement.
3.     Mismatch of parenthesis.

Explain some common Errors:
1.  Typing Printf or print instead of printf.
2.  Forgetting a semicolon (;) at the end of an executable C statement.
3.  Mismatch of paranthesis.

Que 15. Explain Format Specifiers.
Ans. Format Specifiers are % sing followed by a letter which actually prints the value of the variable. Following are the list of format specifiers used in C to print the value of variables of different types.
%c
Character format Specifiers
%d
Signed Integer format Specifiers
%f
Floating point format Specifiers
%lf
Floating point format Specifiers
%s
String format Specifiers
%u
Unsigned Integer format Specifiers
%n
Prints nothing

Chapter 6
Moving Ahead with Scratch 1.4
Que 1.  How to move sprite randomly covering  whole stage?
Ans :-    Scratch stage ranges from -240 to 240 horizontally and -180 to 180 vertically. To randomly glide sprite across the entire stage we can use following code.

Que 2.  What is the use of Sensing block –key pressed?
Ans : -  Many times we want a program to respond to a key pressed on the keyboard. For example, if we want to use the keys ‘b’ to make the sprite bigger and ‘s’ to make the sprite smaller by 10% each time they are pressed respectively, the given code block will be used.


Que 3.  How will you prevent the sprite from going into the boundary of the stage while moving it on stage?
Ans : - With the help of ‘ if on edge bounce’ from the motion block we can prevent  the sprite from going into the boundary of the stage while moving it on stage.


Que 4. What is the use of generating random numbers in Scratch?
Ans  :-  Random numbers in sprite can be used in games to move a sprite to an unpredictable position on the stage each and every time which adds a surprise element and makes the game more interesting and challenging for the player.

Que 5.  Explain with an example the application of sensing keys in scratch.
Ans : -  Many times we want a program to respond to a key pressed on the keyboard. For ex. This script will make the sprite say “Hello” for 2 seconds whenever you press the Spacebar key.


Que 6.  Create a simple game using scratch.
Ans : -








Que 7  What will be the output of the following script block.

  - 

a)    


Sprite will move 10 steps or sprite will move 50 steps.

b)     

- Sprite will change the colour randomly.

c)   

   - Sprite will say hello for 1 second when spacebar key is pressed.

d)    

 - Sprite will move along with mouse pointer and when mouse is clicked, sprite will move to center of the stage.
