The Lesson
OBJECTIVE Can recognize at a glance the memory slots and the card slots on the motherboard
Motherboard is the central printed circuit board (pcb) that contains the processor and integrates all the peripheral input and output to and from the computer (or other electronic system).
Cards are used to extend the functionality of a computer. That is, they add a function. For example, a video card allows the computer to be plugged into a monitor. A sound card allows a computer to be plugged into speakers. (Sometime these functions are built into the motherboard - sometimes a card needs to be added.)
Memory is used for temporary storage and workspace. It will "remember" what you are typing into the computer while the computer is on. This is different than permanent storage (like a hard drive) in that whatever is in memory will fade away quite quickly when you turn your computer off. Memory is often called "Random Access Memory" or "RAM" for short.
It is important to know the difference between memory and cards when looking at them. It is also important to know where in the motherboard each would plug in.
Cards plug into a motherboard in such a way that one end is visible from the back of the computer. This means that the card slots will be pointing towards the back of the motherboard, and nothing will be in their way to reach the back. (You can determine which edge of the motherboard is the back by looking for connectors for the keyboard and other devices that are built in.)
Memory is also plugged into the motherboard, but will be completely inside the computer when it is fully assembled, so they are unlikely to be pointed towards the back, or if they are pointed towards the back, then there will likely be other stuff in their way.
- Some types of cards
- sound cards
- video cards
- network cards
- modems
- wireless cards
- there are many types of cards
- Some common types of memory
- DDR
- RAMBUS
- SDRAM
Questions
- Can you find where the memory would plug into this motherboard?
- Can you find where the cards would plug into this motherboard?
- Find a stick of memory.
- Find a card.
