Networking concepts 1. What are the two types of transmission technology available? (i) Broadcast and (ii) point-to-point 2. What is subnet? A generic term for section of a large networks usually separated by a bridge or router. 3. Difference between the communication and transmission. Transmission is a physical movement of information and concern issues like bit polarity, synchronisation, clock etc. Communication means the meaning full exchange of information between two communication media. 4. What are the possible ways of data exchange? (i) Simplex (ii) Half-duplex (iii) Full-duplex. 5. What is SAP? Series of interface points that allow other computers to communicate with the other layers of network protocol stack. 6. What do you meant by "triple X" in Networks? The function of PAD (Packet Assembler Disassembler) is described in a document known as X.3. The standard protocol has been defined between the terminal and the PAD, called X.28; another standard protocol e...

History of rail transport in India A plan for a rail system in India was first put forward in 1832, but no further steps were taken for more than a decade. In 1844, the Governor-General of India Lord Hardinge allowed private entrepreneurs to set up a rail system in India. The East India Company (and later the British Government) encouraged new railway companies backed by private investors under a scheme that would provide land and guarantee an annual return of up to five percent during the initial years of operation. The companies were to build and operate the lines under a 99 year lease, with the government having the option to buy them earlier. Extent of Great Indian Peninsular Railway network in 1870. The GIPR was one of the largest rail companies at that time. Map of the Madras and South Mahratta Railway lines Two new railway companies, Great Indian Peninsular Railway (GIPR) and East Indian Railway (EIR), were created in 1853-54 to construct and operate two ...
