Identifying Expansion Module Cards

Expansion Card - Is a printed circuit board that can be inserted into an expansion slot of a motherboard to add additional functionality to a computer system. One edge of the expansion card holds the contacts (the edge connector) that fit exactly into the slot. They establish the electrical contact between the electronics (mostly integrated circuits) on the card and on the motherboard.The primary purpose of an expansion card is to provide or expand on features not offered by the motherboard.

Modem Card

Identifying Memory Module

Memory Module - A device that are used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer.

• Volatile memory is computer memory that requires power to maintain the stored information.
• Non-volatile memory is computer memory that can retain the stored information even when not powered.

Types of Memory Module
