My friend I know very well that you will be astonished about these terms that what do they mean. Actually these are not the same things there is a little difference between them. Here we will explain a little bit about them.
As it is evident by its name, Random access memory. That’s why we called it random access memory to collect data. We can reach to any memorial cell through RAM. That process is called random access. RAM is form computer data. A second term is SAM it is also working just like as RAM function. But there is a little difference between them. RAM is small in size but well functioning and it is more obedient. Now we technically briefly explain about them.
We also called SAM (Serial access memory) as it is evident by its name it brings together the data in order and collect then into memorial cell. A method to reach them is only in particular order. It the data is not exists and available in the required place then we will check the entire data in particular order. The SAM is also operating and functioning in the same method. SAM works very well for memory buffer and the data exist in memory buffer in such order to use it which is.
