RAM

  Hello and welcome to Tomexplace! 

  

 

I am not sure if im talking to my self or not, but if there is anyone who been following my posts, you may notice that I was missing for four weeks.  

It's because I had alot of work to do, then again the holydays came, Chrystmas and the New Year, had to celebrate and stuff, you know.

I was drinking alot, partying,

well I celebrated the new year as it should be celebrated.

So yeah, It's too late to say this but, I had to get my shit together after all the celebrations but anyways, happy new year to everyone who reads my shit, if there is anyone who reads.

Allrigh! I am back now!

Im gonna make this new post, this will be the first one in this year!

 

In this post I will writte about the RAM.

No! I wont writte about the Male sheeps or cars.

Im gonna writte about the computer's RAM.

I am sure that everyone has heard about it, if you havent, read bellow and I will explain it to you.

So what's the RAM?

RAM is a memory. Random Access Memory (RAM) is a primary memory in computer in order to operate, also called ; system memory. 

When you open the computer's case, you will see something like this plugged into the motherboard

That's the Random Access Memory (RAM), primary memory, system memory.

Why computer need RAM?

 

The only task RAM has to do is, to let the processor read data from the harddrive, but the data isn't on the harddrive anymore when the processor is reading them, the data is on RAM.

It probably didn't make a sence to you, so I will explain it in common way...

Imagine, you just made a dinner for your guest. For example, you baked potatos, they are still on hot pan, you can't give the pan to the guest, you need a bowl. 

Well, you can, but the guest may leave soon after that.

So, what do you do? You put potatos in the bowl and then give the dinner to your guest, thats what I would do.

Basically, The pan (harddrive) is where the potatos (data) are stored, you take the potatos (the data) and put them in the bowl (RAM), then your guest (processor) is able to eat (read) them.

Ram takes the data from the harddrive, then the processor reads the data from the RAM. 

If you forget what RAM is, remember the potato pan.

Shit! I love those sweet potatos!

Every time when you open the program it gets loaded from the harddrive into the RAM, where the processor can fast access it.

Reading data from the RAM is much faster than reading data from the harddrive.


Running programs from the RAM allows them to function without any lag time. The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can speed up your computer. If you want to increase the computer's speed, adding more RAM can increase it's speed better than upgrading your processor.

The more RAM your computer has, the better! 

If you want to know how much RAM you have in your computer,
open controll panel > my computer > Click properties.

When you open up a folder on your computer, a game, watching a movie or listening music, its on the RAM, when you open anything into your computer it gets stored into RAM, untill its closed. 

If too many programs are opened the computer will swap the data in the memory between the RAM and the hard disk drive, slowing down some programs.

Well, If you are using your computer for nothing more than checking e mail, writting some documents, or just reading your daily news, then 2GB of RAM should be enough for you.

If you are a gamer, or doing lots of work with your computer like, video editing or graphical editing that takes alot of performance, then go for as much as you can get. Basically 16 GB should be enough for you, well, 8 GB that could be the minimum.

In my computer, I have 2 GB of RAM and for me its enough. Somethimes I am playing WoW, getting a little lag, low fps, but I dont complain, I can enjoy the game, plus I am listening to music and the internet browser is open when I play, and with 2 gigs of RAM, its still playable.



In order to work, RAM requires to have power. RAM is active memory, its not holding any data for ever, only while you are using them. The RAM requires power, when you turn off the computer all the data on RAM is lost.

Basically, you are writting something in MS word and sudenly, the power disconnects and computer is shat down. When the power is back on and you turn on the computer, all your work is lost.

While you were working on that document it was stored into the RAM, you didn't had a time to hit the save button, to save all your work on the harddrive. When you save your work, only then it gets stored on harddrive, until its opened, its on RAM and since RAM needs power to work, without power everything that's on the RAM is lost.

Types of RAM

The RAM chip may be plugged in the motherboard or in sets of  chips on a small board connected to the motherboard. Older memory types were in the form of chips called dual in-line package (DIP).  DIP chips are still in use today, the majority of memory is in the form of a module. A printed circuit board added to connector on the motherboard. The three main RAM circuit boards types containing chips are RIMMs (Rambus in-line memory modules), DIMMs (dual in-line memory modules) and SIMMs (single in-line memory modules). Most motherboards today use DIMMs.

There are two main types of RAM, dynamic random access memory (DRAM) or Dynamic RAM and static random access memory (SRAM). The RAM in most  computers is a Dynamic RAM. All dynamic RAM chips on DIMMs, SIMMs or RIMMs have to refresh every few milliseconds by rewriting the data to the module.

Static RAM (SRAM) is volatile memory and is used in cache memory and registers, because it is a lot faster and does not require refreshing like Dynamic RAM. SRAM is able to operate at higher speeds than DRAM, because DRAM is a lot cheaper than SRAM, the computer manufacturers use DRAM.

Dynamic RAM is memory that needs refreshing, the refreshing is done by the memory controller which is part of the chipset on the motherboard. Static RAM (SRAM) does not need refreshing and it's used in memory cache on the central processing unit (CPU) it is called L1, L2 and L3 cache.

 Installing RAM.

Installing RAM is pretty easy itself but you need to do some research about your computer before you purchase the right one. You can buy the wrong chip, and it wont fit into your motherboard slot.

You need to know what type of RAM to buy, putting in the wrong chip into the slot can cause damage to the chip and your system.

RAM is usually sold in multiples of 16 megabytes: 16, 32, 64, 128, 256, 512, 1024 (which is the same as 1GB). This means that if you currently have a system with 64 MB RAM and you want at least 100 MB RAM total, then you will probably need to add another 64 MB module.

FINAL THOUGHTS

Well, it wasn't much, I could explain more about RAM, but I think, it's way beyond these posts, most important now is to understand what RAM is and for what it's necessary, so here I covered the basics. So yeah, you can scratch the head and think about it, there are many more types of ram, the form factors of ram etc, most important is to know what kind of RAM you need to upgrade computer's speed. As I wrote, motherboard slots must support it, You need the right type of RAM that computer can support, and in my opinion the more RAM, the better, once you know everything, installing is easy.

Even tho the holydays are over, I still have alot of work to do, in perssonal life and job, I am not sure when I will post the next post, but when I'll get a free time, I will get my hands on it. I will make new posts, alot more new posts!

Some weeks I will be active, some weeks less.

Well that's it for this post now, good luck, have fun, cheers! 

Tomex.
