In the first session we will be knowing gist of everything..
More than 1.3 billion people live in Indian sub-continent. India is a land of many cultural livings, “Unity through Diversity” is the main attraction to India by many of the foreign countries. Like USA, India is also a Federal Union where almost all of its states carries different Language, different cultural identities. That is why it is known as a sub-continent.
- Indian civilization is ancient
- The Indus Valley Civilization was one of the first civilizations on earth
- The Vedic period was a time in Indian history when the Hindu religion and caste system began in India
- Mughal Empire was the last and the strongest Islamic empire in India
Here in India we see people in,
- People with different clothing
- People with different religions
- People with different foods
- People with different celebrations
- People living in different localities like Urban, Semi-urban, Rural
India is mainly classified into four major sections
- North India : New Delhi
- Eastern India : Kolkata
- Western India : Mumbai
- South India : Chennai
Indian people across the nation eat different food as per their geographical availability.
- Meat-however, cows are considered sacred by Hindus, many of whom are vegetarian
- Tea, Coffee
Religion in India is characterised by a diversity of religious beliefs and practices. The Indian subcontinent is the birthplace of four of the world’s major religions; namely Hinduism, Buddhism, Jainism and Sikhism. With this people in India also follows Christianity, Islam also.
Important Historical Monuments in India
India is home to many historical monuments such as
Taj Mahal, Brihadishwara Temple, Mysore Palace, Harmandir Sahib, Ajanta Ellora Caves, Mahabalipuram, Khajuraho and the list is a long one. We will see about this in a separate video.
Traditional Music of India
Hindustani and Carnatic are popularly known traditional music of India.
Hindustani means classical music of North India
Carnatic means classical music of South India
Melody, Drone, Thala are some of the traditional elements of Indian Music.
String, Wind, Percussion are some of the most commonly used Instruments in India.
Traditional Dances of India
Dance is an ancient and celebrated cultural tradition in India. Folk dances abound all across the country, and huge crowds of people can be found dancing at festivals and weddings. Dance and song features heavily in Indian cinema too. Indian dance draw its roots from six of the most important classical dance forms.
They are: Bharatanatyam, Kathakali, Kathak, Manipuri, Kuchipudi, Odissi.
Welcome to the second session of computer awareness series. In the last session, we have seen about the history of computers and different types and usage of computers.
In this session, we will be knowing about the components of computer system.
Components of Computer System
A computer performs five major functions no matter what size they are of as follows:
- Data or Instructions are accepted as input,
- Data and Instruction are stored
- Processing of data as per the instructions,
- Control of all operations inside the computer
- Result in the form of output.
Based on this Any computer system divided into four basic units;
1, input unit,
2, storage unit
3, central processing unit
- Arithmetic logic unit
- Control unit
4, output unit
Basic Components of Computer Systems
Data and instructions must enter the computer system before any computation can be performed on the supplied data.
The job of an output unit is just the reverse of that of an input unit. It supplied information and results of
computation to the outside world.
The data and instructions that are entered into the computer system through input units have to be stored
inside the computer before the actual processing starts.The Storage Unit or the primary / main storage of a computer system is designed to do all these things. Itprovides space for storing data and instructions, space for intermediate results and also space for the final results.
Central Processing Unit (CPU)
Central Processing Unit
The main unit inside the computer is the CPU. This unit is responsible for all events inside the computer. It controls all internal and external devices, performs “Arithmetic and Logical operations”.
The control Unit and the Arithmetic and Logic unit of a computer system are jointly known as the Central
Processing Unit (CPU). The CPU is the brain of any computer system.
Arithmetic and Logic Unit (ALU)
The arithmetic and logic unit (ALU) of a computer system is the place where the actual execution of the
instructions take place during the processing operations. All calculations are performed and all comparisons (decisions) are made in the ALU. The data and instructions, stored in the primary storage prior to processing are transferred as and when needed to the ALU where processing takes place. No processing is done in the primary storage unit.
The control unit directs and controls the activities of the internal and external devices. It interprets the instructions fetched into the computer, determines what data, if any, are needed, where it is stored, where to store the results of the operation, and sends the control signals to the devices involved in the execution of the instructions.
In the next lesson we will see about Input output devices of computers.
