Difference Between Memory and Harddisk Space

KeyWords: Up the Down Orange!

What is the difference between Memory (RAM) and Harddisk space?

As most people are not aware these are 2 completely different objects. Although Memory is usually taken as the "Hard Drive" of a computer it is not. When a computer nerd, such as myself, refers to Memory we are refering to the RAM of a computer. Not how many pictures you can store on your computer. I will attempt to explain the differences between these 2 similiar but completely different objects.

Memory or RAM as some people like to call it refers to Random Access Memory. It is versatile, meaning anything kept in this memory is erased once power is taken from it. RAM holds vital program information that is only needed for the time the program is running. This also doubles as your resources for a program. In order for a program to run it has to be ran at the Binary level. Depending on how big the program is and what the program needs to do the more RAM the program needs.

On average a program can use up anywhere from 1 MB of ram to 62 MB's (usually games only take up 62 MB's of ram). Since RAM is versatile when that program is through executing (closed) that memory is "freed" up. I put freed in quotes because in reality the memory is only freed up when the computer is restarted or turned off. The more memory you have the better off your computer system is. On average a computer running XP needs a minnimum of 256MB. I would recommend 512MB's at least.

When you upgrade the memory on any computer the difference in speed, efficency, and reliable is amazing. You will notice the difference right away. Instead of it taking 5 minutes to open up Internet Explorer it takes 5 seconds. Not only that it can open IE and Adobe Photoshop at the same time with minnimal lag time. Memory is very important for how your computer performs.

Harddisk space, also know as harddrive space also known as HDD is vital for storing pictures, word documents, music and anything else a computer can house. What many people do not understand is that you have more than plenty HDD space in your computer if that is all you use your computer for. The average HDD size is 40Gigs. which is roughly 80,000 pictures (640x480 res). That is alot of pictures! When your harddrive gets full the only thing that happens is you cannot put anything else on there until you clean some of it off or get an extra HDD.

A HDD will only decrease your computers performance if it is done through USB instead of IDE or the HDD is old and outdated. A HDD is non-versatile unlike RAM or Memory. This means that when your computer is turned off chances are you will not lose any data stored on that HDD. This is great so you can store programs, documents and images without having a fear of losing those documents. HDD's are wonderful tools.

Now that you know the difference between HDD's and RAM I expect you to know that when your comptuer is starting to act up, you probably need more ram, or a clean start. I will get into the clean start on another blog.

Go tell your non-geeky friends that their computer problems have to do with "Memory" and see if they would delete pictures to free up memory. If they do you can so graciously correct them!

Thanx soo much for that, Unfortunely I had brought a addition hd to boost my game game, but got extra ram from computers so hopefully it play better. now what is the differnce between 64ram and 128mb. I got a feeling that 64ram is higher, can't be sure!?

64mb ram has half the memory as 128mb ram. So 128 will be better.
