72-pin SO-DIMMs, 144-pin SO-DIMMs, 160-pin SO-RIMMs and credit card memory
RIMM, SIMM, and DIMM.
That is the physical memory, there is swap memory that used harddisks and bunches of other memory types.
Hard drive, ROM (read-only memory) and RAM (random access memory)
Common types of DIMM Memory Modules used in computers are a 168 pin SDRAM Module, or a 184 pin DDR SDRAM. These boards are designed to be used in personal computers.
Four types fo removal memory devices would be external hard drives, USB memory drives (flash drives), memory cards, and DVDs or CDs. Which of these devices you would choose to use would depend on your individual needs.
You can look for pictures of various memory types (individual chips and memory modules) by doing a google images search or on Wikipedia.
Yes. The memory modules that come installed in most home PCs will not hold up to the stress of being overclocked. There are many aftermarket memory modules, one of the more notable companies being Corsair and Kingston. However, if you really want to push into overclocking memory, I would find a motherboard that runs DDR3 memory modules and invest in a couple, as DDR3 just by design run a little faster than DDR2 and run significantly cooler than DDR2.

Flash memory is a term used for solid state devices. They are called solid state because they have no moving parts and the data is "flashed" to the device. Mobile phones use flash memory, USB storage devices or even large mass storage devices can be bought as solid state.
Keyboard and touchpad are input devices, but they have output aspects, such as the CAPS LOCK light indicator on a standard PC keyboard. Typical output devices on a standard computer include the video adapter with the monitor or display, the sound adapter with loudspeakers, the printer. Many other devices are bidirectional in nature (hard disks, memory cards, all types of network or bus connectors) and can thus be counted among the output devices.
"Hardware devices" usually refers to such items as hard drives, ssd drives, optical drives, graphics cards, add on cards such as ethernet cards, usb cards, memory modules, and the list goes on and on.
There are many different types of memory modules, a more specific question is needed to supply a decent answer. Also the amount of memory in a normal home computer has a limit of between 2 and 4Gb
