Primary DNS servers host original zone files and distribute copies to secondary servers. Primary memory is the computer memory that is directly accessible by CPU.

Comparing primary and secondary storage devices Primary storage devices are costlier than secondary storage device whereas Secondary storage devices are cheaper compared to primary storage device. Secondary sources are closely related to primary sources and often interpret them. Primary data is an original and unique data which is directly collected by the researcher from a source such as observations surveys.

Primary memory is the main memory of computer system. These sources are documents that relate to information that originated elsewhere. Discrete data is the type of data that has clear spaces between values while continuous data is a data that falls on a continuous sequence.

There is a clear distinction between these two terms as this article highlights. Primary index is defined on an ordered data file. But the most important difference is that primary data is factual and original whereas secondary data is just the analysis and interpretation of the primary data.

What is the Difference Between Taeniasis and. The main difference between primary and secondary index is that the primary index is an index on a set of fields that includes the primary key and does not contain duplicates while the secondary index is an index that is not a primary index and can contain duplicates. Difference between Primary and Secondary Memory.

As opposed to secondary data which is easily accessible but are not pure as they have undergone through many statistical treatment. What is the exact differences between Primary index Secondary index and clustered index. Primary data are pure in the sense that no statistical operations have been performed on them and they are original.

Learn the difference between primary and secondary DNS servers. Primary sources can be described as those sources that are closest to the origin of the information. Home Library of Congress.

Secondary sources contain information from different primary sources all in one place. There are many differences between primary and secondary data which are discussed in this work. Difference Between Categorical and Quantitative Data Difference Between Numbers and Numerals Difference Between Discrete and Continuous Data Difference Between Area and Surface Area Difference Between Variance and Covariance.

A source is considered scholarly when the authors were not directly involved in gathering the original information. Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. Depending on the source it can classify as primary data or secondary data.

It holds the data and instructions that the processor is currently working on. While primary data is collected with an aim for getting solution to the problem at. Difference between Primary Storage and Secondary Storage Data storage is a common term for archiving data or information in a storage medium for use by a computer.
