Probably the most common challenge computer users face when using a computer, which involves memory, or lack of their computer.
Computer support technicians will tell you that computer users are often unclear on the different types of memory in their computers. Users often interchange memory into storage, and vice versa. Statements such as “I have eight gigabytes of disk,” or “I have a terabyte of memory” tell computer support people that they behave a novice when it comes to computer terminology.
We do not want you to appear as a novice, so break down the concepts and examine these two parts of your computer, how they work together, and how they affect the performance of your computer.
Difference between memory and storage
Your computer’s main memory is called RAM. You can think of it as the workspace that a computer uses to work. When you double-click an app, or open a document, or, well, do anything, RAM gets used to storing that data while the computer is working on it. . Modern computers often come pre-installed with 4, 8, 16 or more gigabytes of RAM.
There is also storage: a hard disk drive or solid state drive where data has been recorded and can be recalled as necessary can remain indefinitely. It can be a poem in a tax return, a word processor or an email. By comparison, RAM is unstable – when the power is turned off or when the computer resets, the information inserted in it disappears. Stuff written to disk remains permanently until it is erased, or until the storage medium fails (more on that later)
What is RAM
RAM takes the form of computer chips – integrated circuits – that either rest directly on your computer’s main logic board or are installed in memory modules that go into a socket on your computer’s logic board.
RAM means random access memory. Data stored in RAM can be accessed almost immediately, regardless of where it is stored in memory, so it is much faster – milliseconds faster. RAM contains a very fast path to the computer’s CPU, or central processing unit, the brain of the computer that does most of the work.
RAM is random access as opposed to sequential access. Sequentially accessed data includes content that is written to your hard disk drive, for example. It is usually written in files, which have a specific start location and end location. We will reach your hard drive storage in an instant.
If your computer requires general purpose, then you probably don’t need to twist its RAM too much. In fact, depending on the computer you buy, you may not be able to replace the RAM very well. (Apple and others have removed RAM upgradeability from some of their lower-end or portable computers, for example).
If your computer is older and upgradeable, putting in more RAM helps it load and use more applications, more documents, and slow down large files and swap that data on to disk, We will cover below.
If you work with very large files – large databases, for example, or large image files or videos, or if the apps you work with require large amounts of memory to process their data, So having more RAM in your computer can help a lot in performance.
What is computer storage
Computers require some form of non-volatile storage. This can keep a location data even when the computer is not in use and it is turned off, so every time you use the computer, you have to reload and re-enter each time Will happen. It is a matter of having storage other than RAM.
Storage for most computers in use today includes a drive, a hard drive, or a solid state drive. Drives can provide a lot of space that can be used to store applications, documents, data, and all the other stuff that you need to do your job (and your computer needs to operate).
No matter what type of drive you have, storage is almost always slower than RAM. Hard disk drives are mechanical devices, so they cannot access information as quickly as memory. And storage devices in most personal computers use an interface called Serial ATA (SATA), which affects the speed at which data can be transferred between the drive and the CPU.
So why use a hard drive? Well, they are cheap and available.
In recent years, more computer manufacturers have begun offering solid state drives (SSDs) as a storage option in addition to or in place of traditional hard disk drives.
SSDs are much faster than hard drives because they use integrated circuits.
