Primary Storage: Random Access Memory (RAM)

random access memory

Random Access Memory, or RAM, is the computer’s main memory. When you work on a file on your computer, it temporarily stores data in your RAM. RAM allows you to perform daily tasks such as opening applications, loading web pages, editing a document, or playing games. It also allows you to jump from one task to another without losing your progress. The larger your computer’s RAM, the smoother and faster multitasking.

RAM is volatile memory, which means that it cannot store information when the system is shut down. For example, if you Copying a block of text, restarting the computer, and then trying to insert that block of text into a document, you will find that your computer has forgotten the copied text. This is because it was only temporarily stored in your RAM.

RAM enables a computer to access data in random order and reads and therefore writes much faster than secondary storage on a computer.

Hard Drives (HDD):

The hard disk drive (HDD) is the original hard disk drive. These are magnetic storage devices that have been around since the 1950s, though they have evolved over time.

A hard drive consists of a stack of rotating metal disks known as plates. Each spinning disk has trillions of small fragments that can be magnetized to represent bits (1s and 0s in binary code). An actuator arm with a reading/write head scans the turntables and magnetizes fragments to write digital information to the hard disk or detects magnetic charges to read information from it.

Hard drives are used for TV and satellite recorders and servers as well as storage on laptops and PCs.

Solid State Drive (SSD):

Solid-state drives emerged much more recently in the 1990s. SSDs do not rely on magnets and disks, but instead, use a type of flash memory called NAND. In an SSD, semiconductors store information by changing the electrical current of the circuits inside the disk. This means, unlike hard drives, that SSDs do not require moving parts to function.

Because of this, SSDs not only run faster and smoother than HDDs (HDDs take longer to gather information due to the mechanical nature of their plates and heads), they also generally last longer than HDDs ( with so many intricate moving parts, HDDs are vulnerable). damage and wear).

Outside of newer PCs and high-end laptops, you can find SSDs in smartphones, tablets, and sometimes camcorders.
