There are a lot of similarities between Pittsburgh and Jamshedpur.
Some of them are:
(i) Both have an early start.
(ii) Both are located fairly close to raw material source.
(iii) Both are well connected by roads and railways.

(i) The inputs for the iron and steel industry are raw materials such as iron ore, coal, and limestone, along with labour, capital, site, and other infrastructure.
(ii) The process of converting iron ore into steel involves many stages. The raw material is put in the blast furnace where it undergoes smelting and then it is refined.
(iii) The output obtained is steel, which may be used by other industries as raw materials.

(i) TISCO is located in Sakchi, Jamshedpur and has many geographical benefits. This place is only 32 km away from Kalimati station on the Bengal- Nagpur railway line.
(ii) It is close to the iron ore, coal and manganese deposits as well as to Kolkata, which provides a large market. TISCO gets coal from Jharia coalfields, and iron ore, limestone, dolomite, and manganese from Odisha and Chhattisgarh.
(iii) The Kharkai and Subarnarekha rivers ensure sufficient water supply.

The significance of Agro-based industries in Indian Economy is as follows:
(i) Indian economy is purely an agriculture based economy.
(ii) The industrial development of the country depends on the development of agriculture.
(iii) Agriculture provides raw materials.
(iv) Agro based industries provide employment to hundreds of people.
(v) The product of the agro-based industries are exported to other countries and thus our country earns huge foreign exchange.
(vi) These industries also supply many valuable products to the people of our country.

The industrial system consists of inputs, processes and outputs.
(i) The inputs are raw materials, labour, costs of land, transport, power and other infrastructure.
(ii) The processes include a wide range of activities that convert the raw material into finished products.
(iii) The outputs are the end products and the income is earned from them.

The differences between information technology industry in Bengaluru and Silicon Valley are:
(i) Silicon Valley has both software and hardware companies, whereas Bengaluru has only software companies.
(ii) The cost of development of software is lower in Bengaluru as compared to Silicon Valley.
(iii) Bengaluru is located on Deccan Plateau which has mild climate throughout the year whereas, Silicon Valley has temperate climate.

(i) The early computers were extremely expensive and large, requiring a lot of space.
(ii) The invention of a small electronic device called chip or IC, changed the shape, size, and capabilities of the computers.
(iii) The development of chip led to the availability of small, powerful and affordable computers and related equipments, which became a key reason for the growth of IT industry.

The world's major industries are the iron and steel industry, the textile industry and the information technology industry.
1. Locations of iron and steel industry are:
 Germany, USA, China
2. Locations of textile industry are
India, Hong Kong, South Korea, Japan
3. Locations of information technology industry are
Silicon Valley of Central California, Bangalore region of India.

In the secondary activities or manufacturing there is change of raw materials into products of more value to people.
For example pulp changes into paper and paper into notebook. These represent the two stages of the manufacturing process.

Iron and steel industry is located at Jamshedpur due to the following factors:
(i) Manganese is obtained from Keonjhar district of Odisha.
(ii) Well-developed network of transport is available.
(iii) Kolkata provides port facilities.
(iv) Cheap and skilled labour is available from the nearby states.

Similarities between information technology industry in Bangalore and California can be drawn as follows
1.Bangalore is located in Deccan.Plateau while Silicon Valley in California is located next to the Rocky mountains.
2.Both have clean environment.
3.Pleasant climate throughout the year.
4. In the vicinity of educational, scientific and technological centres.
5. Close to major roads and airports.
6.Good access to markets.
7. Both have skilled workforce.
8. Low or affordable cost of living.

Cotton textile industry has rapidly expanded in Mumbai because of its warm, moist climate, facility of port for importing of machinery and above all because of the easy availability of skilled labour.

1. Iron and steel industry is often referred to as the backbone of the modern industry. This is because almost everything is either made from iron or steel or has been made using tools and machineries of these metals.
2. There are plenty of examples like ships, trains, vehicles; all are made largely of steel. Materials of our day-to-day use starting from safety pin to our building in which we live, are made from steel. Without the use of iron, no industry can run.

Food processing, vegetables oil, cotton textile, dairy products and leather industries are some agro-based industries.

The shirts which we all use are made up of cotton which is grown in fields. Cotton buds are plucked and cotton is separated. Cotton seeds are also separated and then it is processed for spinning. In early days, it was done by hands or looms. Now, machines are used which are run by power. After spinning, the weaving process starts and cotton clothes are ready for making shirts which we use. This process involves power, labour and capital in big amount.
