The main storage device of a computer where all data is saved. Hard drives are non-volatile which allows the data to be saved even when the computer is shut down. “Although most hard drives are internal hard drives, many users also use external hard drives to backup data on their computer and expand the total amount of space available to them”( "What Is Hard Drive?" Computer Hope. Web. 14 Sept. 2014.) The first Hard Drive was released by IBM in 1956.
Random Access Memory (RAM):
Another form of computer storage, RAM is what allows data to be accessed and read from random parts of a computer. RAM is volatile memory which means it can lose data being stored in it when the power is shut off. ”RAM is the most common type of memory found in computers and other devices, such as printers” (Beal, V. (n.d.). RAM - random access memory. Retrieved September 14, 2014.). When you start getting low on RAM the operating system then dumps some of the open programs from the RAM to the hard drive which can increase load times.
Solid State Drive (SSD):
Solid state drives are actually quite a bit different than hard drives in that they are able to transfer data faster and also don’t have moving parts that can break down. They are also non-volatile memory units. The first Solid state drive was implemented in IBM supercomputers in the 1970s and 1980s. Unlike Hard drives and how they save using magnetism, Solid state drives save with interconnected memory chips that save even when no power is available (Domingo, Joel. "SSD vs. HDD: What's the Difference?" PCMAG. Web. 14 Sept. 2014.). Cloud Storage:
Cloud Storage is data that is stored in logical pools, where the physical storage is across multiple servers at certain locations. Many companies like Google and Amazon use cloud storage as they only pay for storage they use, can be used as a backup after natural disasters due to multiple backup servers...
