Charles Babbage - Father of Computing - Born December 26, 1791 in Teignmouth, Devonshire UK, Died 1871, London; Known to some as the "Father of Computing" for his contributions to the basic design of the computer through his Analytical machine. His previous Difference Engine was a special purpose device intended for the production of tables.
IP Spoofing and Sniffing - Sniffing and spoofing are security threats that target the lower layers of the networking infrastructure supporting applications that use the Internet. Users do not interact directly with these lower layers and are typically completely unaware that they exist. Without a deliberate consideration of these threats, it is impossible to build effective security into the higher levels. Sniffing is a passive security attack in which a machine separate from the intended destination reads data on a network. The term "sniffing" comes from the notion of "sniffing the ether" in an Ethernet network and is a bad pun on the two meanings of the word "ether." Passive security attack are those that do not alter the normal flow of data on a communication link or inject data into the link.
History of TCP/IP - Internetworking with TCP/IP has been around for many years-almost as many years as Unix has been available. TCP/IP, or Transmission Control Protocol/Internet Protocol, grew out of the work that was done with the Defense Advanced Research Projects Agency, or DARPA. In 1969, DARPA sponsored a project that became known as the ARPANET. This network mainly provided high-bandwidth connectivity between the major computing sites in government, educational, and research laboratories.
Network Topologies - Ever wonder... how are all of these file, print, fax, and computer resources connected so as to allow the typical desktop computer to access them? Network topology refers to the way networked computers and network resources are connected. The three most widely used topologies are bus, ring, and star. Note that the following network topology diagrams are logical views of the topologies they represent and don’t necessarily match the physical (electrical) interconnections on the networks.

IT Jobs - What's Out There? - In this article, we would like to point out the obvious IT Jobs that at times get overlooked. Find out what's out there and which information technology is the right choice for you. From people that create laptop computers to folks that do web design to developers that come up with computer software concepts from scratch. Also a bit at the end about computer schools and computer training.
Comparing Apples and Androids - When the iPhone made its debut on June 29, 2007 the world went crazy. People lined up for blocks, camped out on sidewalks for days just to be the first to get their hands on the phone that would change their lives forever. However in 2009 iPhone 3G (3g Phone) was released and the mayhem started over. The iPhone seemingly had cornered the Smartphone market in spite of its hefty price tag of $600. Of course the price dropped significantly and those who waited could purchase the iPhone for under a $100.
But ... lurking in the shadows was a phone which would give the iPhone a run for its money. It was similar in style to the iPhone and could be customized to suit the user’s needs—the Droid. T-mobile launched the Google phone or the G1 was officially in the hands of gadget lovers on October, 2008. The G1 was the first to use the Google Android software and cost a mere $179 with a 2 year contract. T-Mobile allowed customers to pre-order the phone to ensure customers had the phone in hand on the official release date.
Web Hosting For All the Other Reasons - Most of the times you'll hear web hosting companies promote their services as some cheap solution for a site that may have scalable needs. This is a fancy way of saying they believe you're website will one day require tremendous amount of hosting resources because they have all the faith in its success. We'll I don’t want to say that we don’t have the faith, but maybe the promoting web hosting service can be done for a "host" of other reasons as well.
Types of PC Cases - Computer cases come in a variety of colors, designs, materials and for those who wish to bare all, there are clear acrylic cases available. You'll hear of all types of hardware lingo like: ATX computer cases, full tower computer cases, desktop computer cases, custom computer cases, aluminum computer cases, cheap computer cases, gaming computer cases, mini computer cases, and on and on and on...you get the drift.
IT College Program vs. IT Boot Camp - Perhaps it is time for a career change, or you are fresh out of high school and the idea of four more years of schooling does not appeal to you. You want to jump into the working world and start earning some cash, fast. After much research you have decided to embark upon a career in the Information Technology field. Not a bad choice, especially since Technology changes every day.
You are faced with the choice of education. As previously stated, going to computer school for four years to get a computer science degree is not an option but there is another option, IT Boot Camp. And IT Boot Camps solely focus on a very limited number of IT Certifications. So there can be MCSE Boot Camps that may focus on just that. But some bigger computer schools will deal with number IT Certification Training.
Outsourcing of US Jobs - In 2008, global economy saw the worst downturn in decades. Some even compared it to the "Great Depression" of 1930s. Millions all over the world lost their jobs and consequently their homes that they had on mortgage. It is believed that crisis spiraled through inability to repay the mortgage loans. US took the major hit of this slowdown and millions lost their means of livelihood. Big financial companies went bankrupt overnight leading to a large head count of jobless people in America. While all this was happening there were countries like India, China, and Philippines who were snapping up jobs generated inside the US borders.
HTML5 - Setting New Standards in Hypertext - HTML5 is the latest buzz word in web development world. It comes with a lot of cool, new features and most importantly it aims at bringing consistency to the whole process of web development. The code is much cleaner, neater and standardized. For example, web software developers can replace the div tags with neat HTML5 elements. This also means that web developers across the board can read and understand code better even if they know nothing about the language because of the standardization. This also ensures that web developers building new hosted web applications can understand the features better and integrate well with it. The overall semantics would improve because of the new HTML elements and it would be easy to see the structure of the code and determine the header, footer, navigators etc.
Types of CPU's (Processors) - Upgradation is not something new to the field of computers. The computer has come a long way from being just a calculating machine to a device that has become a necessity everywhere. There is no industry or business that can't benefit from the usage of computers. Whether it's a managed server used for dedicated server hosting, personal desktop computers, or just your student friendly notebook computers. The number of ways we can benefit from computers are numerous. The main component of a computer has seen great changes in the past. First generation computers made use of magnetic core memory whereas second generation saw the advent of transistors. It was in the third generation which began in the 1960s that gave rise to microprocessors.
History, Origins, and Generations of Computers - Origin of computers was a gradual development from the room size UNIVACS to the hand held palm tops today. This improvement was possible due to the discovery of many new technologies which reduced processing time, size and cost. Computer history is classified into generations based on the discovery which led to major change. The computers in these generations differ greatly from its previous and next ones.
Types of Servers 2 - One of most important type of server is cluster servers. Software that enables clustering of servers is installed into a computer. Clustering servers also serve as load balancing servers between two computers. This is a common small business server. Clustering servers are used to avoid server failover. Server failover is the capability to shift to another standby server if the main server fails.
