Solution is here∗ Make a Computer Network.∗ Just we need one printer and one CD ROM and other device.∗ How it’s possible?∗ With Network every thing is possible.∗ Share those devices among all computers.∗ So all computers can use those devices.∗ And costs are will goes down.
Why? Use a Computer Network!∗ In computers network we can (share nodes, clients, workstations and servers)∗ can share: ∗ Files ∗ Resources ∗ programs
Shareable & Non Shareable Shareable 1: Hard ware 2: Soft ware1: Printer, CD Room, Flash, Floppy, Modem.2: Any S/w Non ShareableMouse, Keyboard, Camera, MIC & etc.
