Week 3 Post 1 Revision

 Computers store data on hard drives and removable drives using a hierarchical system. The hierarchical system consists of the File System which is the overall structure that a disk drive uses to store, retrieve, and organize data. Following the File System is the Directories/Folders, they act as containers for files and other directories. Directories can be nested within each other to create subdirectories. Lastly is the Files themselves, a file can contain any type of data and is stored in a directory. 

My current backup plan was put in place after losing countless personal files after I had them all stored locally on my cellphone and said cellphone was dropped in the ocean. I have 3 copies of any and all-important information i.e., bank statements, military record, medical documents, and any documents pertaining to anything currently being financed just to name a few. Three copies on my cellphone which is backed up to the cloud and can be remotely wiped thanks to AVG antivirus in the event of theft or loss. Three copies on my computer which is linked to my phone, backed to the cloud, and can be remotely encrypted with an AES-128 encryption in the event of loss or theft via windows Find My Device feature BitLocker, this blocks anyone from accessing your data without your recovery key. I can also remotely wipe my computer using Windows Intune. I always keep three physical copies of any information in a very heavy gun safe in my garage. Personally the only challenges I've found in having this backup plan in place was getting my wife to start doing the same thing with any data/ information she has. 

RAM is a type of computer memory that is used to temporarily store and quickly access data that the computer is currently using or processing. RAM's main role is to provide temporary storage for data that is being actively used by the processor. RAM allows the processor to access this data quickly, making your computer run more smoothly and efficiently. RAM is volatile which means it loses any data it has procured in the event of shutdown/ restart. On the other hand, a hard drive is non-volatile, so it retains its data even when the computer is turned off or restarted. It's COMMON for computers to have hard drives that can store several terabytes of data and RAM that can store between 4GB and 64GB of data. RAM is much faster than a hard drive, RAM is used for data that the processor needs to access right away whereas hard drive are much slower but are used for long term storage.

My laptop has 16gb and is currently using 6gb to run my browser and Hulu. While you can operate a computer with less RAM, having more RAM generally provides a smoother, faster user experience, particularly when running multiple applications or using memory-intensive programs. It's important to balance the amount of RAM in your system with your specific needs and the types of applications you typically run.
