Questions about ram

Hi all,

could you explain below term in simplest way and mind giving me some example?

I cant get it even until now

 

 

Sequential Read    
Sequential Write    
Random Read
Random Write

[flashiling]

so you're asking what Sequential Read/Write and Random Read/Write does?

Basically how fast you can read from the ram.

Edit I guess I should clarify. This is a very very basic explanation really. There's more to it but.

Sequential read is a disk access pattern whereby large contiguous blocks of data are read from adjacent locations on the surface of a device at a queue depth of one. The term is used primarily within the context of benchmarking and the speed is usually measured in MBps. This type of access pattern is common when reading large files such as video, music and images. As a rule of thumb approximately 50% of a typical users disk access on a PC will consist of sequential reads and writes. Drives that are used primarily for large multimedia files or backups should have relatively high sequential read speeds. When manufacturers quote speeds for devices such as flash drives, hard drives and SSD's, unless specified otherwise, they are referring to the sequential speed. Other types of read speed include random 4k and deep queue depth.

 

found this on google

didn't mean that to mock you or anything, but there are a lot of websites explaining theese things
