Class 5 Social Studies Chapter 11 Notes from Recording and Communicating Knowledge
What is Knowledge?
Knowledge is a form of information about any subject. Knowledge is the understanding of any subject.
The exchange of knowledge is important in our life as our lives depend upon information about a variety of subjects.
Knowledge is exchanged:
🡲 By speaking to someone. (Orally)
🡲 By writing and sharing the information.
Importance of Recording Knowledge
Orally exchanged information can be lost with the years. People can forget the information. Knowledge also remains with a limited number of people.
If the information is written or recorded in some way then it has a better chance to reach to many people and also it will stay intact over the years. So recording any information is important. People can read or see this recorded information any time anywhere.
Earliest Forms of Written Communication
What is a Script?
A systematic collection of signs and symbols is called a script. Some scripts have pictorial symbols and others have alphabets. These signs and symbols are given some sounds. These sounds make the language.
Pictures ⇒ Signs and Symbols ⇒ Scripts ⇒ Alphabets and Numbers ⇒ Language
Examples of scripts
Roman alphabets have 26 letters – A to Z.
Oldest Indian script – Indus Valley Script
Devanagari Script – Our Hindi letters.
Roman Numbers – I, II, III, and so on.
Hindu-Arabic Numbers – 0 to 9 developed in India about 2000 years ago.
The Invention of the Printing
The invention of printing was a revolutionary idea as it made it possible to print books. Several copies could be printed by some printing techniques. More and more books reached the people and knowledge was transferred.
|Printing was developed in China about 2000 years ago.
The Chinese cut designs on flat blocks of wood.
The ink was applied to the blocks.
Blocks were pressed on paper.
|In 1443, Johann Gutenberg used several small metal molds of letters for printing in Germany.
Molds containing letters were created.
(These molds are called types)
These molds were arranged to form words, sentences, and paragraphs.
(This arrangement is called typesetting)
Typesets were applied with links and pressed on the paper to get impressions.
Invention of Paper
(Class 5 SST Chapter 11 Important Notes)

🡲 In Braille script, words are printed in dot patterns.
🡲 These dots are little raised over the surface and can be read by touching them.
Knowledge, Literacy, and Progress
Sharing knowledge is very important. People become literate and knowledgeable. Literacy and knowledge can help in the progress of any country.
🡲 Computers and advanced printing technologies have made the recording and sharing of knowledge very easy and faster.
🡲 The Printing systems are very compact in size and printing can be done with minimal effort.
🡲 There are various applications are available for making and printing words, pictures, etc.
