C. Answer the following questions:

1. While working on the computer, you notice that the
system is working very slowly, files are corrupted,
default home page on the web browser has changed, lot
memory is consumed, and unnecessary pop-ups are coming.
 What can be the probable reason?

Answer

The computer gets infected from Spyware. It monitors user
activity on the Internet and transmits that information
in the background to someone else. Spyware can also
gather information  about e-mail addresses and even
passwords and credit card numbers. It also sends
information back to the spy ware’s home base via the
user’s Internet connection, thus it eats user’s internet
bandwidth.

2. You have very important data on your computer. How
will you ensure that this data remainssafe?

Answer
We can make our important data safe on computer through below steps:
1. Using Security software such as Norton antivirus,
Symantec etc.
2. Beware of email attachments form unknown sources
3. Do not randomly download material from websites
which has not been checked for security.
3. Never propagate hoax or chain emails.
4. Frequently back up important data and files.
5. Use encryption or sites that use encrypted data.

3. Differentiate between virus, worms and Trojan horses.

Answer
Virus- A computer virus is a program usually hidden with
in another simple program. It produces copies of itself
and inserts them into other programs or files, in turn
destroying the data and performing other malicious
 actions. Computer viruses are never naturally
occurring; they are always man-made.

Worms- Worms are very similar to viruses in the manner
that they are computer programs that replicate copies
of themselves (usually to other computer systems via
network connections). Unlike viruses, worms exist as
separate entities; they do not attach themselves to
other files or programs.

Torjan Horses- A Trojan horse is a program that claims
to rid your computer of viruses but instead introduces
viruses into the system. The Trojan program does not
attach itself to the files like a virus nor replicate
itself like a worm but it does provide unauthorized
access to user’s computer. They are mostly spread
through internet downloads and online gaming programs.
They mostly affect the targeted computers.

4. How is a hacker different from a cracker?

Answer

Hackers were the gifted programmers who gain access to the systems or network to show case the security loopholes to the administrators.
Cracker was activist who had intentions of doing malicious activities. Crackers have an end goal of destroying data and network for personal monetary gains.

CBSE computer book chapter 3 : Memory

            Chapter 3       
        COMPUTER MEMORY

Que1: What is memory?
Ans:
Memory is an essential element of a computer.
Without its memory, a computer is of hardly any use.
Memory plays an important role in saving and
retrieving data. The performance of the computer
system depends upon the size of the memory.

Que2: Write memory types?
Ans:
Memory is of following types:

1. Primary Memory / Volatile Memory.
2. Secondary Memory / Non Volatile Memory.

Que3: What is primary memory / Volatile Memory?
Ans:
Primary Memory / Volatile Memory:
Primary Memory is internal memory of the computer.
RAM AND ROM both form part of primary memory.
The primary memory provides main working space to
the computer.

Que4: Discuss on primary memory types as RAM?
Ans:
The following terms comes under primary memory of a
computer are discussed below:

Random Access Memory (RAM): The primary storage is
referred to as random access memory (RAM) because
it is possible to randomly select and use any location
 of the memory directly store and retrieve data.
It takes same time to any address of the memory as
the first address. It is also called read/write memory. The storage of data and instructions inside the primary storage is temporary. It disappears from RAM as soon as the power to the computer is switched off. The memories, which lose their content on failure of power supply, are known as volatile memories .So now we can say that RAM is volatile memory.

Que5: Discuss on primary memory types as ROM?
Ans:
Read Only Memory (ROM): There is another memory in
computer, which is called Read Only Memory (ROM).
Again it is the ICs inside the PC that form the ROM.
The storage of program and data in the ROM is
permanent. The ROM stores some standard processing
programs supplied by the manufacturers to operate
the personal computer. The ROM can only be read by
the CPU but it cannot be changed. The basic input/
output program is stored in the ROM that examines
and initializes various equipment attached to the
PC when the power switch is ON. The memories, which
do not lose their content on failure of power supply,
are known as non-volatile memories. ROM is
non-volatile memory.

Que6: Write about ROM types?

Ans:
PROM: There is another type of primary memory in
computer, which is called Programmable Read Only
Memory (PROM). You know that it is not possible to
modify or erase programs stored in ROM, but it is
possible for you to store your program in PROM chip.
Once the programmers’ are written it cannot be changed
and remain intact even if power is switched off.
Therefore programs or instructions written in PROM or
ROM cannot be erased or changed.

EPROM: This stands for Erasable Programmable Read Only
Memory, which overcome the problem of PROM & ROM.
EPROM chip can be programmed time and again by erasing
the information stored earlier in it. Information
stored in EPROM exposing the chip for some time
ultraviolet light and it erases chip is reprogrammed
using a special programming facility. When the EPROM
is in use information can only be read.

Cache Memory: The speed of CPU is extremely high
compared to the access time of main memory. Therefore
the performance of CPU decreases due to the slow speed
of main memory. To decrease the mismatch in operating
speed, a small memory chip is attached between CPU and
Main memory whose access time is very close to the
processing speed of CPU. It is called CACHE memory.
CACHE memories are accessed much faster than
conventional RAM. It is used to store programs or
data currently being executed or temporary data
frequently used by the CPU. So each memory makes
main memory to be faster and larger than it really is.
It is also very expensive to have bigger size of cache
memory and its size is normally kept small.

Registers: The CPU processes data and instructions
with high speed; there is also movement of data
between various units of computer. It is necessary
to transfer the processed data with high speed. So
the computer uses a number of special memory units
called registers. They are not part of the main memory
but they store data or information temporarily and
pass it on as directed by the control unit.


2. Secondary Memory / Non-Volatile Memory:  Secondary memory is external and permanent in nature. The secondary memory is concerned with magnetic memory. Secondary memory can be stored on storage media like floppy disks, magnetic disks, magnetic tapes, This memory can also be stored optically on Optical disks - CD-ROM. The following terms comes under secondary memory of a computer are discussed below:

    Magnetic Tape: Magnetic tapes are used for large computers like mainframe computers where large volume of data is stored for a longer time. In PC also you can use tapes in the form of cassettes. The cost of storing data in tapes is inexpensive. Tapes consist of magnetic materials that store data permanently. It can be 12.5 mm to 25 mm wide plastic film-type and 500 meter to 1200 meter long which is coated with magnetic material. The deck is connected to the central processor and information is fed into or read from the tape through the processor. It’s similar to cassette tape recorder.


    Magnetic Disk: You might have seen the gramophone record, which is circular like a disk and coated with magnetic material. Magnetic disks used in computer are made on the same principle. It rotates with very high speed inside the computer drive. Data is stored on both the surface of the disk. Magnetic disks are most popular for direct access storage device. Each disk consists of a number of invisible concentric circles called tracks. Information is recorded on tracks of a disk surface in the form of tiny magnetic spots. The presence of a magnetic spot represents one bit and its absence represents zero bit. The information stored in a disk can be read many times without affecting the stored data. So the reading operation is non-destructive. But if you want to write a new data, then the existing data is erased from the disk and new data is recorded.  For Example-Floppy Disk.


    Optical Disk: With every new application and software there is greater demand for memory capacity. It is the necessity to store large volume of data that has led to the development of optical disk storage medium. Optical disks can be divided into the following categories:

    Compact Disk/ Read Only Memory (CD-ROM
    Write Once, Read Many (WORM)
    Erasable Optical Disk
