What's the difference between DDR2 SDRAM and a serial-ata hard disk drive?

Question

I'm getting a notebook that has this:

2GB PC4200 DDR2 SDRAM (upgradeable)
200GB 4200RPM Serial-ATA hard disk drive

But people keep telling me it has a 2GB hard drive and that that's not a lot, but wouldn't the hard drive be 200GB? If it is 2GB, how much stuff would I be able to save on my notebook?

Answer 1

The people you're talking about are just as confused!

The hard drive is what you use to store data. So that means you'd have a 200GB drive, which is awesome for a laptop. It would take you a very long time to fill that drive.

The 2GB of DDR2 is referring to memory. Memory is what the PC uses while it's turned on. As your computer opens/closes programs, memory is getting heavily used because it is a lot quicker than your hard drive. But because of the way it works, RAM erases itself when the power is off. That's why you have to have a hard drive too to save information.

Answer 2

the two processor would be nice for you. As a school pupil, the small ameliorations in processing time heavily isn't a area for you. the two laptops have 4 Gig of memory, and that's an substantial element for somebody who saves music and %. and in all probability movies as nicely. the different substantial factors are the demonstrate screen length and the cost. i might think of which you will possibly like the sixteen inch demonstrate screen; the bigger it incredibly is, the greater fulfilling the experience. So, all different issues being equivalent (which is composed of value), i might circulate with the bigger demonstrate screen. If there is an substantial distinction in value (and that i think that the AMD processor would be greater affordable) and value is a challenge for you, then the AMD computer is a powerful selection as long as you do not techniques the smaller demonstrate.

Answer 3

They're probably telling you to get 2GB of memory. Memory and hard drives are not the same thing. Memory refers to Ram and 2GB is more than enough. 200GB for a hard drive, depends on what you are going to use it for. I deal with lots of media and videos so 200GB wouldn't cut it for me but for every day average use, it is more than enough.

Answer 4

U r so .. so.. confused !

SDRAM refers to the memory of the cpu used for the processing work .
High RAM will make ur compu .. run faster
A 2GB ram is PARADISE . ALL the games run. The computer is ready before u switch on the computer power
The best thing its WINDOWS VISTA READY

ATA hard drive is memory 2 store ur files
200 GB is 2much2use Its true ;
i doubt u will ever fill that much songs ,movies,games or ne other damn thing ur computer.

Answer 5

the 200 GB harddrive is the permanant storage the 2GB DDR is the RAM which is temporary storage - when you are using the computer the programs (or parts of the programme) are taken from the harddrive and put into RAM (because it is a lot faster)

Both the 200GB harddrive and the 2GB DDR RAM are adequate
