Internet Backbone Speeds - This is something that can come in handy for those of you who are simply curious about internet backbone speeds.
Networking Terms and Topics, Simplified! - This very much to the point guide highlights some important networking terms and topics and simplifies them to us, the mere mortals.
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.
How to Connect Two Laptops Using Bluetooth - Do you need to copy a heavy file from another laptop without using pen drive or connecting cables? Of course, this can be done by using electronic transfer methods like ftp or online data storage systems. However, these methods are not only time consuming, they often lead to increased data transfer costs. Moreover, what if there is no internet connectivity available in the immediate vicinity? Under such circumstances, you can connect two laptops through Bluetooth and exchange files seamlessly.
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.
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.
227 Categorized CompTIA A Plus Q and A - CompTIA A+ Certification is widely recognized as the first certification you should receive in an information technology (IT) career. Whether you are planning to specialize in PC hardware, Windows operating system management, or network management, the CompTIA A+ Certification exams measure the baseline skills you need to master in order to begin your journey toward greater responsibilities and achievements in information technology.
CompTIA A+ Certification is designed to be a "vendor-neutral" exam that measures your knowledge of industry-standard technology.
The number one goal of this Q and A tutorial is a simple one: to help you pass the 2009 version of the CompTIA A+ Certification Essentials Exam (number 220-701) and the Practical Application Exam (number 220-702), and thereby earn your CompTIA A+ Certification.
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.
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.
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.
Brief History of Wi-Fi - Wi-Fi would certainly not exist without a decision taken in 1985 by the Federal Communications Commission (FCC), America's telecoms regulator, to open several bands of wireless spectrum, allowing them to be used without the need for a government license. This was an unheard-of move at the time; other than the ham radio channels, there was very little unlicensed spectrum. But the FCC, prompted by a visionary engineer on its staff, Michael Marcus, took three chunks of spectrum from the industrial, scientific and medical bands and opened them up to communications entrepreneurs.
Getting Into IT - No Experience No Qualification - But how? If you have computer skill but no experience (or qualifications), the employment agencies will tell you the same old line, "You need experience before anyone will look at you."
It's just plain old Catch-22. You need the work to get the experience but you can't get that first job to give you a track record and therefore verifiable experience. With this logic, it amazes me that anyone actually gets into IT!
Qualifications help but even that is no guarantee nowadays of getting an IT Job. And what do you do when you don't have qualifications but you want to start now? I mean right now, not 3 months later after you've paid a fortune for certification and given up your job to have enough study time.
All is not lost. You have two alternatives.
What is Computer Networking?
A network is a collection of connected intelligent computing devices. The connection is not necessarily a fancy one. A connection between two computers by direct cabling is qualified to be a network. By this definition, a workstation which is loaded with a computer, a scanner, and a printer, is not treated as a network.
A network can consist of two computers connected together on a desk or it can consist of many Local Area Networks (LANs) connected together to form a Wide Area Network (WAN) across a continent. The key is that two or more computers are connected together by a medium and are sharing resources. These resources can be files, printers, hard?drives, or CPU number-crunching power.
A Local Area Network (LAN) is a smaller network within one location or between several buildings A Metropolitan Network (MAN, politically incorrect, no WOMAN!) is a midsize network spanning the city. A Wide Area Network (WAN) is a giant network spanning across several cities or even several continents.
