what is Unbuffered Memory
This is regular memory for computers. The computer reads data directly from the memory banks making it faster than buffered memory. However, there is a limit on the amount of RAM that can be installed.
what is buffered memory
This is specialized memory for servers and high-end workstations that use a large amount of RAM. These memory chips have a control chip built into the module. The control chip assists the memory controller in managing large quantities of RAM. Avoid buffered RAM for a gaming computer and the average workstation because the extra controller chip reduces RAM speed.
how to install optical drives
Step 1. From the front of the case, choose the drive bay that you want to hold the drive. Remove the faceplate from that bay if necessary.
Step 2: Position the optical drive so that it aligns with the 5.25 inch (13.34 cm.) drive bay opening at the front of the case, as shown in the figure.
Step 3. Insert the optical drive into the drive bay so that the optical drive screw holes align with the screw holes in the case.
Step 4. Secure the optical drive to the case using the proper screws
what are secure digital SD
SD cards were designed for use in portable devices such as cameras, MP3 players, and laptops. SD cards can hold as much as 2 TB of data.
What is CompactFlash
CompactFlash is an older format, but still in wide use because of its high speed and high capacity (up to 128 GB is common). CompactFlash is often used as storage for video cameras.
what is system speaker
The motherboard uses a case speaker (if available) to indicate the computer’s status. For example, one beep indicates that the computer started without problems. If there is a hardware problem, a series of diagnostic beeps is issued to indicate the type of problem. It is important to note that the system speaker is not the same as the speakers the computer uses to play music and other audio. The system speaker cable typically uses four pins on the system panel connector.
