If they were, the devices would all have to have a separate interpreter for the processor and in order to communicate amongst themselves they'd have to go through the processor, which would slow the computer down. If everything is connected to the motherboard and the motherboard interprets everything for the processor, it's cheaper and faster.
Memory drives are peripheral devices that are very useful
A PC card is used to connect peripheral devices to a notebook computer.
No. It is not a part of CPU but an external peripheral connected to it.
Expansion Boards
The camera memory card does not need to be directly installed into the Pictbridge port on the printer. The Pictbridge port is a receptacle that when properly connected can allow easy transfer of compatible devices.
Peripheral devise are the computer devices that are connected to the computer externally such as printer, scanner, keyboard, mouse, tape device, microphone and external modem. They can be internal such as CD-ROM or internal modem and external as the scanner, printer and Zip drive. Peripheral devices can be classified according to their functions.InputInput devices are the type of the computer devices that are used to provide the control signals to the computer. Keyboard and the Mouse are the examples of the input devices.OutputOutput devices are the devices that are used to display the results. Printer, scanner, speaker and the monitor are the examples of the output devices.StorageA storage device is a device that is used to store the information such as hard disk drive, flash drive, floppy disk and the tape drive.
AOU The first advantage is a great reduction in number of peripheral devices. The two cores can share memory resources, so the number of memory devices can also be reduced. Furthermore, space-saving benefits from shared I/O and bus can also be expected.
