Dear Parents
Sub : Summer Vacation Holiday Homework
Even in these critical times of the COVID pandemic, the school has, as always, kept
the interest of the students the primary focus. Our untiring efforts have earned us a
very good and encouraging response from the students and the parents.
To minimise academic loss, we are continuing to put in our best efforts so that your
ward utilises his/her summer break in an efficient way.
We will resume classes in June 2021, as per the Government guidelines and
directives issued in due course of time. The relevant details will be notified to you
accordingly.
As always,please check your email regularly for important updates like holiday
assignments, date sheet, syllabus for unit tests and more.
Kindly encourage your ward to complete the holiday assignments (given in the next
page/s)
While the children are at home kindly encourage your ward to do the following as
well:
1. Journal Writing
Journaling for self-esteem is a great way to improve your mood regarding yourself, your mental health, and your body. By getting any negative thoughts out and
bringing more positive ideas to life, you will feel your spirits being lifted.
Maintain a journal and write on the following topics:
On a daily basis, write 3 things you did (other than studies) which you are
proud of. Try to make this list longer every day.
Write one activity you did which makes you feel guilty. Make a promise
with self to confess and apologize for bad behaviour, to the concerned
person. Make a promise to self to never do it again. Then forgive yourself.
What is best compliment you have been given? How did it make you feel?
Who is your role model? Why do you admire this person?
2. Do something creative everyday: Art, cooking, gardening, playing music,
making handmade objects, which are a part of experiential learning.
3. Apart from these, your ward must be encouraged to do Yoga / Physical
Exercise / Dance / Aerobics in the morning etc to keep themselves physically
active and healthy.
As suggested by the school in our earlier notice regarding covid awareness and diet
plan, you must encourage your ward to consume a balanced diet for their well being
and to keep themselves fit and healthy.
Stay home and stay safe.

SUBJECT : COMPUTER
Important Notes:- Ch-1 Moving Ahead With Computer System
Primary Memory
(i) ROM (Read Only Memory) .The data and instructions stored in ROM can only be retrieved for an
application in the user's program but nothing can be written or modified in it. ROM is programmed to
store system commands, library functions and other programs.
(ii) RAM (Random Access Memory):It is a volatile memory, i.e. the contents get erased as soon as power
supply is switched off. The application programs i.e. the programs and data supplied by the users get red
in this area of primary memory. After the execution is over, the contents are either shifted to secondary
memory for permanent storage or deleted from it.
Cache Memory: CPU works faster than any other device in a computer. This speed mismatch creates difficulty
in data transfer between 1/0 devices and processor. Hence, a high speed storage device is needed in between a
CPU and the 1/0 devices. It can supply data to the CPU with the same speed as the CPU requires. It is known as
cache memory, pronounced as 'Cash memory. Hence, a cache memory is a high speed memory, capable of
providing data to the CPU from RAM - memory
Ports
Ports are the connecting nodes that act as interface between the peripheral devices and the processor. They are
also known as communication ports. They act as bridge between external devices and CPU for data
communication, Some of the ports are explained below:
a. Serial Port: It is a serial communication physical interface through which information transfers in or
out one bit at a time (in contrast to a parallel port). It uses single wire for communication. Earlier, in
personal computers, data was transferred through serial ports to devices such as modems, terminals
and various peripherals.
Serial ports are usually available with 9 pins or 24 pins and allow the mouse, the modem, etc. to
connect to computer. Serial ports are becoming outdated because they take too much time to transfer
data. But they are still used in industrial automation systems, scientific instruments, shops, some
industrial and consumer products Server computers may use a serial port as a control console for
diagnostics. Network equipment (such as routers and switches) often use serial console for
configuration.
b. Parallel Port: A parallel port is a type of interface found on computers (personal and otherwise) for
connecting peripheral devices. In computing, a parallel port is a parallel communication physical
interface which is also known as a printer port.
This type of port is available with 24 pins female connector and is capable of transmitting eight bit
signal at a time i.e., the transfer rate is eight times faster than a serial port. This port is provided to
connect the CD-writer, scanner, printer, hard disk, etc.
Today, the use of parallel port interface has decreased because of increase in Universal Serial Bus
(USB) and FireWire devices along with network printing using Ethernet
c. USB Port: Universal Serial Bus (USB) is standard for connectors used for a communication and
power supply between computers and electronic devices. USB was designed to standardize the
connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers,
portable media players, disk drives and network adapters) to personal computers, both to
communicate and to supply electric power.
