2.1 RAM Types

There are various types of RAM available, including DDR4 (Double Data Rate 4), DDR3, and DDR2. Each generation offers improvements in speed and efficiency. DDR4 is the most common and widely used RAM type in modern systems, providing faster speeds and lower power consumption compared to older generations.

It's essential to check the motherboard specifications to ensure compatibility with the desired RAM type and maximum supported capacity. Mixing different RAM types or using incompatible RAM can lead to system instability and compatibility issues.

Additionally, some motherboards support multiple channels for RAM, such as dual-channel or quad-channel configurations. Utilizing multiple channels can provide increased memory bandwidth and improved performance.

2.2 Virtual Memory (Page File)

In addition to physical RAM, computers also utilize virtual memory, also known as the page file, to supplement the available memory. Virtual memory uses a portion of the computer's storage device, usually the hard drive or solid-state drive, to temporarily store data that doesn't fit in RAM.

While virtual memory allows the system to run more applications or handle larger files, it is significantly slower than physical RAM. When the system relies heavily on virtual memory due to insufficient RAM, overall system performance may be affected, resulting in slower response times.

Increasing the amount of RAM in your computer can reduce reliance on virtual memory and improve system performance. It's important to have enough RAM to handle your typical workload to avoid excessive usage of virtual memory.

3. Storage Devices

Computer storage devices are responsible for storing and retrieving data. There are several types of storage devices, each with its own advantages and disadvantages. The two most common types of storage devices are hard disk drives (HDD) and solid-state drives (SSD).

Hard disk drives are traditional mechanical storage devices that use spinning magnetic platters and read/write heads to store and retrieve data. HDDs offer large storage capacities at a relatively low cost. However, they are slower compared to solid-state drives and can be more prone to mechanical failure.

Solid-state drives, on the other hand, use flash memory to store data, resulting in significantly faster read and write speeds compared to HDDs. SSDs are more durable and reliable due to having no moving parts. However, they generally have lower storage capacities and are relatively more expensive per gigabyte than HDDs.

Hybrid drives, also known as SSHDs, combine the benefits of both HDDs and SSDs. They feature a traditional HDD with a small SSD cache for frequently accessed data, providing improved speed while maintaining larger storage capacities.

3.1 Hard Disk Drives (HDD)
