Operating Systems
When you buy your computer, it is likely that it comes pre-installed with an operating system. As a result, many people do not know much about them or what an operating system consists of. For example Windows is a common operating system that has multiple requirements. You must have a processor, 1GB of RAM, 16GB hard disc space, and a graphics card. There are also additional requirements to run specific additional features. The latest version of Windows is Windows 10 which has more advanced requirements to be able to run on a computer.
Chrome OS is another operating system created by Google. The major selling point of Chrome OS is simplicity. It delivers what netbooks promised, focusing on web apps while avoiding the complexity of other operating systems. Although it was originally intended to be an online only operating system, that did not last because it was an issue for rural areas.
A downside of Chrome OS is that it assumes any internet connection is a good one and proceeds to download updates in the background while the user attempts to run other processes. This can cause a noticeable lag in the computer's speed. A major downside is that Chrome OS cannot run PC games, Microsoft office, Photoshop, Skype or other important programs that can be necessary to both businesses and casual computer users.
A benefit of Chrome OS is that it is cheap in comparison to other operating systems and has other apps to make up for those it lacks the ability to run. Google Docs being a strong competitor with Microsoft Word. It also has minimal training requirements and few security problems as a result of it's simplicity. If you can deal with Chromebook's limitations, it offers and unbeatable value for it's cost.

Memory, RAM, and ROM
Computer memory can be defined as any physical device capable of storing information temporarily or permanently. Memory is not disc storage and is used to allow programs to communicate with the processor at higher speeds.
Memory can be both Volatile and Non-volatile. Volatile loses it's contents when the computer is shut off. Non-volatile keeps it's contents even when power is lost. RAM is an example of volatile memory and EPROM is Non-volatile.
ROM and RAM chips are not the same thing and have a major difference. ROM is used primarily during the start up process of a computer. RAM is used after the start up during normal processes. ROM is volatile and RAM is non-volatile. RAM can store more information that ROM, storing up to 16GB or more while ROM has up to 4MB or more per chip.
Computer Bios is a good example of ROM, and it is also used in gaming system cartridges such as the original Nintendo, Gameboy, Sega Genesis, and more. RAM is the fastest memory in our computer and is used to run programs and the normal processes of a computer. However the downside of RAM is that any information is lost once the computer loses power.
