OK... batch processing is when all the data is collected togther before processing starts, and then input and processd at the same time.

Real time processing is when data is input and processed as it happens in real life or real time.

ok, batch is like for example, electricity bills, u collect EVERYONE's for over the whole month, and then input at the end of the month and process and send out.

but like, airline tickets, when someone makes a booking, the updating is done right away and the seat has been  'reserved' as soon as it is booked, in real time or as it happened.

hope that cleared it?

Can anyone please tell me the definition of

i.Router
ii.Hub
iii.Implementation

Thanks :D
Router>>It's hardware and software are tailored to the tasks of routing and forwarding the information.
It contains an operating system, RAM, flash memory and one or more processors.
It identifies the destination of the messages and send them via an appropriate route.
Hub>>It is a device for connecting each computer or terminal on a network and make them work as a single network segment. It does not manage any traffic that comes through them. Any data packets entering is broadcast out on any other part. Thus pasket collision results which slows down the smooth flow of the traffic.
Implementation>>It is the act of starting to use the computerised system in real situations after having designed and completed it.

switches?

A switch, like a hub, is a device that connects a number of computers together to make a LAN.

The typical use of a switch is at the centre of a star network (or as part of a hybrid network) - the switch has cables plugged into it from each computer.

A switch is a more ‘intelligent’ device than a hub: if it receives a message, it checks who it is addressed to, and only sends it to that specific computer. Because of this, networks that use switches are more secure than those that use hubs, but also a little more expensive.

@sgvaibhav
im sure about the line thingy cz my teacher told me bout it..
As for the switches>>
It is a hardware device that joins multiple computers with one LAN. It identifies data packets as they are recieved determining the source and destination devices and forwarding them appropriately. Thus, it conserves networks bandwidth and has better performance than a hub.
