Hosting can be FREE, SHARED or DEDICATED. Here are some of the most common type of web hosting services available.
Free web hosting is best suited for small sites with low traffic, like personal sites. It is not recommended for high traffic or for real business. Technical support is often limited, and technical options are few. Another name for shared hosting is virtual hosting or mass hosting. It works as follows: your content and applications are placed on a server which is shared with other customers who also use that web host. The equipment and server are owned and managed by the web host provider, with technicians on hand to monitor and manage the servers. Dedicated hosting is designed to give customers a better form of hosting as one customer gets to use a server that could have been shared by many; this gives the customer more reliable hosting service. There are several web hosting companies offering top web hosting solutions at affordable rates. However it is always better to read several web hosting reviews before you select any hosting companies. The common ones are Windows and Linux. Windows web hosting will support features the windows platform while Linux web hosting will support the Linux platform.

Being a newcomer in running a website, you will need a suitable web hosting service first. You can then create and upload the content of your site to the hosting and make it live on the Internet. Buying the right web hosting solution is a very important decision. Whether your website is for an online business, an information resource, a discussion forum, or for sharing views on a hobby or interest; you must use a web hosting service that will allow everyone else to view your creation. It is web hosting that empowers you to share information, sell prodcuts and services, and interact with people through a web site. Trying to choose a web host can be a very confusing exercise, especially when you consider the growing number of web hosts and their confusing advertisements. Therefore, it is important that before jumping in, you go through some sort of a research process for selecting the most appropriate web hosting company for your Internet presence. Web hosting companies usually charge a fee, although there are some services that are free.

Digital ants are an application of Swarm Intelligence. Using SI, these digital ants adapt to the variations of viruses that hackers routinely introduce. When one ant detects a threat, he is soon joined by many others to overwhelm their opponent. The “digital ants” will wander through computer networks looking for invaders. When an ant detects one, it calls for an army of reinforcements to join the fight.

This is critical since security programs gobble up more resources, and antivirus scans take longer and machines run slower when anti-virus packages discover new threats and issue updates. Researchers believe the new ant-based system will run faster than conventional security programs which have to be updated constantly to recognize new infections.

Digital ants cannot survive without software “sentinels” located at each machine, which in turn report to network “sergeants” monitored by humans, who supervise the colony and maintain ultimate control.”They can ramp up their defence rapidly, and then resume routine behaviour quickly after an intruder has been stopped. We were trying to achieve that same framework in a computer system.”

“As they move about the network, they leave digital trails modelled after the scent trails ants in nature use to guide other ants.

“Each time a digital ant identifies some evidence, it is programmed to leave behind a stronger scent. Stronger scent trails attract more ants, producing the swarm that marks a potential computer infection.”

The new security approach is best suited for large networks that share many identical machines, such as those found in governments, large corporations and universities.

A freelancer, freelance worker, or freelance is somebody who is self-employed and is not committed to a particular employer long term. Fields where freelancing is common include journalism, book publishing, journal publishing, and other forms of writing, editing, copy editing, proofreading, indexing, copywriting, computer programming, web design and graphic design, consulting, tour guiding and translating.
Freelance practice varies greatly. Some require clients to sign written contracts, while others may perform work based on verbal agreements, perhaps enforceable through the very nature of the work. Some freelancers may provide written estimates of work and request deposits from clients. Freelancers generally enjoy a greater variety of assignments than in regular employment, and—subject to the need to earn a regular income—usually have more freedom to choose their work schedule. The experience can also lead to a broad portfolio of work and the establishment of a network of clients.

Controller–area network (CAN or CAN-bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer.
CAN is a message based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment.The development of CAN began when more and more electronic devices were implemented into modern motor vehicles. Examples of such devices include engine management systems, active suspension, ABS, gear control, lighting control, air conditioning, airbags and central locking. All this means more safety and more comforts for the driver and of course a reduction of fuel consumption and exhaust emissions.
To improve the behavior of the vehicle even further, it was necessary for the different control systems to exchange information. This was usually done by discrete interconnection of the different systems. The requirement for information exchange has then grown to such an extent that a cable network with a length of up to several moles and many connectors was required. This produced throwing problems concerning material cost, production time and reliability. The solution to the problem was the connection of the control systems through a serial bus system. This bus had to fulfill some special requirements due to its usage in a vehicle.With the use of CAN, point-to-point wiring is replaced by one serial bus connecting all control systems. This is accomplished by adding some CAN-specific hardware to each control unit that provides the “rules” or the protocol for transmitting and receiving information via the bus. CAN or Controller Area Network is an advanced serial bus system that efficiently supports distributed control systems, It was initially developed for the use in motor vehicles by Robert Bosch Gmbh, Germany, in the late 1980s, also holding the CAN license. CAN is most widely used in the automotive and industrial market segments. Typical applications for CAN are motor vehicles, utility vehicles, and industrial automation. Other applications are trains, medical equipment, building automation, household appliances, and office automation.
