1. (17) DVD single layer discs can support up to 4.7 GBs of data and double layer discs (DL) can support up to 8.5 GBs of data. This ups the capacity of a BD-R XL disc to 100 GB and 128 GB, respectively.  (26) Over time,  dust buildup inside your computer could cause overheat and do harm to your computer's components, thus resulting in your computer frequent restarting issues .

2. CPU Cooling (36) Air coolers Air Cooling - Air cooling is the most common type of computer cooling. This category includes the stock fan that your CPU comes with. Air cooling works by first drawing the heat that the CPU generates through a “heatsink”. Liquid Cooling- Liquid cooling is the most popular type of cooling with high-end builds. These are builds which often overclock their CPU’s and generate intense amounts of heat. Liquid cooling works similar to air cooling in that the main point is to draw heat away from the CPU into a medium and then dissipate it. For air cooling, this medium is air. For liquid cooling this medium is water (or sometimes a different liquid like glycol). The heat is absorbed into a water block rather than a heat sink. Immersion cooling/submerged cooling-It is mainly used to cool the data centers of major companies if it’s found that other heating methods are inefficient. Categorically, it is the most efficient form of cooling because the components are in direct contact with the medium – which is dielectric mineral oil. is the most common type of computer cooling. This category includes the stock fan that your CPU comes with

3. DIMM stands for Dual Inline Memory module. DIMM modules offer more memory and a faster data transfer rate, they are frequently utilized in desktop computers. SODIMM modules are not frequently used in gaming computers because they are primarily meant for laptops MicroDIMM is designed for m obile type, slim type, and super lightweight notebook computers . DIMM is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard . (62)

4. (49) eSATA stands for External Serial Advanced Technology Attachment (SATA). eSATA refers to external hard drives, including optical drives and HDDs . eSATA external hard drive can  save and transfer large amounts of data . It has transfer speeds of up to 600MB/s (6GBps). It bypasses speed transfer rate limitations by skipping the USB data channel and using the same channel used by the computer's internal hard drive.
