The Cisco website has very comprehensive steps on how to do this:
http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a00801fc986.shtml

If you want details steps apart from that link let me know, but the basic steps are:
Install a tftp server onto your computer, place the new IOS (firmware) into the folder on your computer.
Connect to your switch (I assume it has network connectivity and you're not using the console cable)
Run the following commands:
#Copy tftp flash
#Address or name of remote host [? (enter you computer IP address)
You will get something like this:

Erasing the flash filesystem will remove all files! Continue? [confirm]y
Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
eeeeeeeeee ...erased
Erase of flash: complete
Loading c2600-adventerprisek9-mz.124-12.bin from 10.10.10.2 (via Ethernet0/0):
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 29654656/49807356 bytes]

Verifying checksum...  OK (0xAC8A)
29654656 bytes copied in 56.88 secs (80383 bytes/sec)The copy process takes several minutes. This time differs from network to network. When the copy process is in progress, messages are displayed that indicate which file has been accessed.

The exclamation point "!" indicates that the copy process is in progress. Each exclamation point indicates that ten packets have transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory.

Sorry missed a section after the "#Address or name of remote host [?"
You wil be prompted for the following:

Source filename ? (Type name of IOS file on your computer)
Destination filename [c2600-adventerprisek9-mz.124-12.bin]? (type y)
Accessing tftp://yourcomputername
Erase flash: before copying? [confirm] (type yes to erase old IOS)

Hi,

Thanks that was simply excellent...

Please advice me whether Firmware & IOS is the same because people always confuse me with the terminology.

Also please advice me the whether I have to change the boot system to this new image after erasing the flash and copying the new Firmware.

Cisco routers/switches will use the first IOS it sees in flash.  So as long as the IOS you want to use is listed first, don;t have to specify it using boot system command.

With that said, I however prefer to tell router or switch which IOS I want it to use and not leave the choice to device.

You can use following command:

no boot system
boot system flash:/<image file name>

They are technically different, but the majority of the time someone refers to the firmware on a Cisco they are actually referencing the IOS.
