Research published in Science Citation Index (SCI) journals with impact factor (IF) has now become a prerequisite for a researcher or a professional seeking placement in reputed academia or research organizations.
What is SCI (Science Citation Index)?
SCI (Science Citation Index) and its companion publication JCR (Journal Citation Reports) are databases of the Institute of Scientific Information (ISI), Philadelphia, USA (http://www.isinet.com). SCI and JCR are the most sought-after worldwide information source (both retrieval and dissemination) and are used for the evaluation and comparison of scientific journals.
What is the impact factor (IF)?
The journal impact factor (IF) in a given year is the ratio of the number of times the citable papers published in the journal are cited to the sum of citable papers published by the journal in the preceding two years. Therefore, it is a measure of citation frequency for a particular year. The value of any scientific publication is assessed by its citation index and measured by its journal impact factor (IF).

These are impact factors of some popular journals. The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor is commonly used to evaluate the relative importance of a journal within its field, you can check the impact factor of a journal, from the above example you may get some ideas about the importance of impact factor.
