Direct access means going straight to the record you want,and random access means pick data randomly and then find that data which you required.

What is the difference between random variable and random variate?
Random variables is a function that can produce outcomes with different probability and random variates is the particular outcome of a random variable.
What is the difference between a biased and unbiased sample?
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
What is the Difference between random and systematic sampling?
Random sampling is picking a subject at random. Systematic sampling is using a pattern to pick subjects, I.e. picking every third person.
What is the difference between random assignment and random sampling?
Random sampling is the sample group of subjects that are selected by chance, without bias. Random assignment is when each subject of the sample has an equal chance of being in either the experimental or control group of an experiment.
Can 9 month old Alpha male kitten pair up with a 4 month old Beta male kitten?
Difference between direct access and random access
What are the techniques of file processing?
The common techniques of file processing include sequential access, random access, and direct access. Sequential access involves reading data sequentially from the beginning to the end of a file. Random access allows reading data from any part of the file without having to read the preceding data. Direct access uses a key or address to locate specific data within the file.
Whats the difference between SDRAM and normal ram?
sd ram is synchronous dynamic random access memory, ram is just random access memory
Differences among sequential access direct access?
Let's say you have a set of 100 pieces of data, which are all names. Now, if you want to find a specific name, "Kevin", you can find it in different ways. You could either go through each of the records one after another, or you could randomly generate a number, and check if that record is "Kevin", this is potentially faster than sequential access as "Kevin" could be the last record.
What is the difference between direct emailing and spam?
Spam is unsolicited to random addresses.
Difference between direct and sequential access?
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
What does ram mean in computer language?
random access memory
What is the difference between direct access and sequential access?
, Both terms "direct access" and "sequential access" as you must have guessed refer to accessing schemes in the file system. In broadest sense difference between these two can be stated like this -In sequential access data is stored at random locations. -In direct access data is stored at sequential locations. ( Ironically this is true No matter what kind of first impression we get when we hear it for the first time. ) -In sequential access addition of data is fast but retrieval of data is slow. -In direct access addition of data is slow as reordering of data blocks may be needed to put current data block after the last used data block for the file. But retrieval of data is fast. -Data structure implementing Sequential access is linked list. -Data structure implementing Direct access is an Array. Application areas:- A situation where rate of addition of data is much larger compared to retrieval of data Sequential access is preferred, in opposite situation Direct access is more suitable. Regards, Prime There are technical explanations as to how it works, but in simple terms, direct access means going straight to the record you want, whereas sequential access means going through all records one by one until you find the one you want.
What are the difference between read only memory and random access memory?
ROM is volatile
What are the main differences between DDR2 and SD ram?
SD ram is synchronized with the with the system clock and runs at the same speed as your computer. DDR2 is random access memory that is used for high speed storage of the working data of a computer.
