The following list is of external storage devices used over the evolution of the computer. Whether you have lots of photos or a colossal music collection, you'll want to invest in more space so your computer can keep up. This concept does not pertain to the primary storage, which is shared between multiple processors to a lesser degree. Removable storage, in computing terms, is any form of data storage which is not incorporated into the computer itself. The most common unit of storage in computer is called a byte which is equal to 8 bits. GB is an abbreviation for gigabyte. As we all know, computer hardware is composed of three parts: the host computer consisting of CPU and memory, system buses, and external devices like secondary storage and other I/O devices. Storage Space – The amount of space you can use to store your files. All data and information fed into a computer, as well as the program that comes preloaded are stored in form of bytes. What does a GB mean? Direct-attached storage (DAS) is a traditional mass storage, that does not use any network. That is, information on it doesn't "go away" when you turn off the system, unlike data stored in RAM. What Does GB Mean and Why Is It So Important? When the computer is running, CPU will transfer the data that needs to be operated from the secondary storage into the memory. When referring to computer storage, “hard drive” (or SSD, see below) is the term typically used. In addition to providing a form of backup by removing data from a centralized computer system, it is also much more portable than an entire computer, allowing people to easily carry data back and forth from a wide variety of locations. The picture is an example of a Drobo and an example of a popular external storage solution. These drives often connect to the computer using USB, eSATA, or FireWire connection. The CPU is often referred to as “the brain” of your computer, so ensuring it’s working properly is very important to the longevity and functionality of your computer. Storage’ refers to long-term storage.Everything that your computer knows, but isn’t thinking about, is in storage, written on the Hard Disk Drive (HDD).This is a permanent type of storage: hard drives can be unplugged and contain the same information as when they’re plugged in or turned on. With hard drives now storing tons of data and SSDs becoming more and more common, your computer's storage can now range from 64GB to 3TB. If you are not familiar with the technology lingo, you may not have a clue as to what GB stands for in the computing world. Computers must use the PCI-Express bus to get the best performance. That's a pretty big range. This is still a most popular approach. For large files and photo storage. Every hard drive has a specific amount of space. Examples of external storage devices. For the sake of context, a high resolution photo takes up about 1 to 2MB while a visually-demanding game takes up to 5GB. The M.2 interface is an advancement in computer storage and performance. Otherwise, it runs the same as any existing SATA 3.0 drive. This doesn't seem like a big deal, but it's a problem with many of the first motherboards to make use of the feature. The traditional spinning hard drive is the basic non-volatile storage on a computer. A secondary or tertiary storage may connect to a computer utilizing computer networks. A computer memory is made up of millions of bytes.
