A geographic information system (GIS) is a software for making maps, analyzing data, and more. This cheat sheet tells you about what you can do with GIS, provides a handy guide to raster-based functions, gives you some key ideas to keep in mind about maps (relating to scales, projections, and datums), and the X, Y, and Z of GIS.

The bioinformatics Web sites in the following list offer help in analyzing DNA and RNA sequences. And, in the marriage of information technology and molecular biology that is bioinformatics, this type of analysis is what it's all about. Webcutter: Restriction map GenomeScan: Gene discovery blastn, tblastn, blastx: Database search The Genome Browser: Browse the ultimate data!

With bioinformatics you can explore molecular biology using information technology. The links to the Web sites in the following list focus on protein sequences. Some offer searchable databases, others help you investigate a single protein; all are helpful: BLAST: Database homology search SRS: Database se

Bioinformatics is the marriage of molecular biology and information technology. Websites direct you to basic bioinformatics data and get down to specifics in helping you analyze DNA/RNA and protein sequences.All of this data comes at you in several formats, so becoming familiar with various format types helps you know how to interpret and store the data.

Virtualization saves money, energy, and space. After you’ve decided to go virtual, take steps to make implementation easier. Get to know some important terms about virtualization, types of virtualization, and leading companies and products in virtualization.Reasons for moving to virtualizationIf you’re trying to decide if virtualization is right for your organization, whether from an economic or technological standpoint, consider these reasons for taking the virtualization plunge: It saves money: Virtualization reduces the number of servers you have to run, which means savings on hardware costs and also on the total amount of energy needed to run hardware and provide cooling.

When planning and implementing your IT architecture, ease the process by reviewing critical information: major IT architecture concepts such as common tasks, standardizing technology, and consolidating and centralizing technology resources; collaboration solutions to institute across the enterprise; and system maintenance processes that can be automated to help you increase savings and reduce administrative overhead.

Your GIS (geographic information system) is very handy and a great navigation tool, but what you see on the GIS screen isn't necessarily what the actual terrain looks like. As you use your GIS, remember the following facts: Map Characteristic What It Means Maps are models — not miniatures Maps generalize geographic features by using symbols so that all features will fit the specified output size.

With GIS (geographic information system) you can do all sorts of geography-related stuff — find places, of course, but also find the best place to locate your business, among other things. The following list summarizes some of the tasks you can accomplish with GIS: Find geographic features. You can search a GIS database to find point, line, area, and surface features by their descriptions or measurements.
