Keyboard is an input device. It has various keys with specific functions. Keys like Alphabet keys, Number keys, Enter keys, delete key, space bar key, caps lock key, Num lock key, Function key, Shift key, etc. This slide will take you through different keys and its functions. For better understanding, I have included pictures of different types of keys.
This lesson is for students taking the Cambridge School certificate exams Computer science subject(2210).I hope that it will of help to students in this period of crisis. Send me your feedback or suggestions on buxooa72@ gmail.com,

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
2. Input/Output
Input is whatever is put into a computer.
Input can be data, letters, numbers, symbols, shapes,
sounds, pressure, light beams or whatever material
needs processing.
Output hardware consists of devices that translate
information processed by the computer into a form
humans can understand - print, sound, graphics, or
video, for example.
3. The Binary System
The base of all programs is the binary system, a
number system of two - 1 and 0.
These represent On and Off - the position for an
electrical signal to pass through (or not) a transistor.
All data and program instructions that go into the
computer to be processed and stored, are
represented by these binary numbers.
4. Decimal System
To understand the binary system, we need to review
our Base 10, decimal system.
The prefix “dec-” means 10
Our decimal system is based on 10 numbers
(0,1,2,3,4,5,6,7,8,9)
When counting, using place value, we fill the ones
place and then move to the tens place.
5. For example:
When you count in the
decimal system (base 10)
you fill the one’s place, then
move to the ten’s place.
Only the numbers 0 - 9 are
used.
As each place value is filled
with the numbers, we
continue to the next place
value. Each place value is
10x the previous place.
10’s 1’s
9
1 0
1 1
1 2
1 3
100’s 10’s 1’s
9 9
1 0 0
1 0 1
6. Counting in Binary (Base 2)
The prefix “bi-” means two.
The binary system uses only two numbers - 0 and 1.
We count in the binary system the same as in the
decimal system by filling in the place values and
moving up the place value chart.
If the decimal system, base 10 has place values 10x
the previous place - How do you think the place
values for the binary system are determined?
13. Bits and Bytes
Bit - In the binary system, each 0 or 1 is called a bit -
short for binary digit.
Byte - A group of eight bits. The letter “G” is a
representation of 1 byte (eight bits).
There are 256 combinations of bits available 28=256
14. The alphabet in binary
Binary Alphabet
O11OOOO1 a
O11OOO1O b
O11OOO11 c
O11OO1OO d
O11OO1O1 e
O11OO11O f
O11OO111 g
O11O1OOO h
O11O1OO1 i
15. Can you read this?

Binary code is the base code of computer
language.
Once you understand the patterns and the
rules, you can learn other programming
languages.
Have fun coding!
