Random Access Memory (RAM) is a hardware component that stores data temporarily while the computer is running. It provides high-speed storage for the CPU to quickly access data that is actively being used. RAM is essential for multitasking and running applications smoothly.

When you open a program or a file, the data is loaded into RAM so that the CPU can access it quickly. The more RAM your computer has, the more data it can store and access at once, leading to improved performance and responsiveness. However, RAM is a volatile memory, which means it loses its data when the power is turned off or during a system restart.

RAM capacity is measured in gigabytes (GB), and most computers typically have 4GB to 16GB of RAM, although higher-end systems can have even more. It is important to have enough RAM to meet the requirements of the operating system and the applications you use to prevent performance issues like slow response times and program crashes.

In addition to the RAM capacity, the RAM speed, measured in megahertz (MHz), also affects the overall performance of the system. Higher RAM speeds allow for faster data transfer, but the impact on real-world performance may vary depending on the specific tasks and applications being used.

3. Storage Devices

Storage devices in a computer are responsible for storing and retrieving data. There are two main types of storage devices: hard disk drives (HDDs) and solid-state drives (SSDs).

Hard disk drives (HDDs) are the traditional storage devices found in most computers. They use magnetic disks to store data and have been around for decades. HDDs offer high capacity at a relatively lower cost, making them suitable for storing large files and applications. However, they are typically slower than SSDs in terms of data transfer speed.

Solid-state drives (SSDs) are newer storage devices that have gained popularity due to their faster performance. SSDs use flash memory to store data, allowing for faster data access and transfer speeds compared to HDDs. They are more durable and less prone to failures since they have no moving parts. SSDs are particularly useful for improving the overall speed and responsiveness of a computer, especially during tasks that involve frequent data access.

Both HDDs and SSDs come in various capacities, ranging from a few hundred gigabytes (GB) to several terabytes (TB). The choice between an HDD and an SSD depends on the specific requirements of the user, including budget, performance needs, and storage capacity.

It is also worth mentioning that computers may have other storage devices such as optical drives (CD/DVD) for reading and writing optical discs and solid-state hybrid drives (SSHDs) that combine the features of both HDDs and SSDs.
