If you are entering this confusing arena, there is a path through the brambles. It is the Cisco Certification programs. Cisco Certifications are earned by completing courses and taking examinations that demonstrate your ability to work at the various levels within the networking field. There are three basic levels of Certification. They are Associate, Professional, and Expert. The Expert level represents the very highest level.

Although there are various methods to prepare for the Cisco Certification exams, one of the most successful have been the boot camps. The boot camps take their name from the military basic training concept of extensive training in a short time period. A CCNA boot camp will prepare you for the Cisco Certified Network Associate level. The camps run from one week to two weeks in duration, and they usually go seven days a week. The good ones prepare the student for more than just the exam. They also prepare him for the work he will do after he receives the certification. This is accomplished through hands on training under the guidance of expert instructors.

CCIE boot camp training will prepare you for that ultimate certification and the expert level in your field. You must have already earned the previous two certificates before attending this advanced class. CCIE boot camp training will not only prepare you for the examination and this highest of all Cisco Certifications, but will also qualify you as a legitimate Master of the networking profession.

It is never too early to begin your career preparation. If you think a career in computer networking is for you, prepare for it as early as high school. Discuss with your guidance counselor which courses will best prepare you for a higher education degree. If you are all ready finished with school, and beginning in the actual work place, examine your options for Cisco Certification based boot camps. It is the fast track to success. In this rapidly growing, and even more rapidly changing field, you need to be on top of the latest technology, or you will be quickly left behind.

Playing with LAN

Gamers of all ages have enjoyed video games through the magic of a local area network. This connects a series of computers together, and enables them to share information. Through LAN, players are able to link their games together, and can play multiplayer games battling each other, and even team up. Some of these games come in the form of first person shooters where the players can be a team of S.W.A.T. officers, a military group, secret agents, interstellar soldiers, and the list goes on. A lot of other genres are also present and make great games because of LAN capabilities.

The rise of MMORPG

Massively multiplayer online role-playing games have been on of the more popular type of games lately. These are your usual role-playing games where you control a particular character, start out with menial equipment, and do a lot of quest in order to become stronger and gain money. MMORPGs have taken this even further. Because of the Internet, players are now able to interact with each other in a virtual environment. In the game, players may choose to trade equipment, help each other with quests, battle each other, and fight monsters side-by-side.

Some games of this genre allow the players to have their own professions so that they can earn the currency of the “world” that they are in (it’s usually gold and silver). These games have become so addictive, because there are so many things that you can do in the games. The interactive world that you are playing in can be so big, that traveling from one place to another could take you a long time. Some gamers have been so addicted that there even has been a story of a guy that was divorced by his wife because of his MMORPG addiction. Well, as long as you are a responsible individual then there should be no problem at all with playing these types of games.

Virtual items

People have become so serious when it comes to these MMORPGs, that it has even come to the point of them buying items used inside the game and using real money. Some would spend hundreds of dollars to acquire items, or even strong characters. There are particular websites where you can auction such items. There are some cases where this is outlawed because you don’t actually buy a tangible item.

Computer networking has made the possibilities of gaming endless. There are countless more innovations to come, and who knows what the next trend might be. It’s a great thing that technology such as the Internet and local area networks are able to bring us better entertainment.

The benefits of networking are considerable, even on a network of only three systems. In computer networking there was never a truer statement than that this is a case of advantages experienced being far greater than the sum of the parts. PC networking is, as a consequence, a rapidly evolving discipline with many exciting opportunities. Challenges that arise in networking and particularly in the Internet tend to be truly global and have the potential to impact upon millions of users.

One huge and growing impact is Internet shopping. Shopping online has grown over the last 10 years to become a huge market, and if a sales business does not today incorporate this technology use they will fall behind their competitors.

But computer networking is also producing much more subtle uses within our societies. For example, Internet technologies can be deployed to favorably condition empathic response in those who have offended against community norms out of a lack of appreciation for the effects that their criminal behavior has on other people. In other words Internet linked devices can track home prisoners to maintain their behavior, in ways that 20 years ago had not even entered the heads of science-fiction writers, to the benefit of society as a whole.

Wireless Internet technology, is the development, also known as WiFi, which is really taking over the way people access the Internet and it has become widely popular in a very short space of time. One reason for this is it allows individuals to access the Internet via a network hot spots, while traveling without the use of cables or wires. In short it releases us from the tyranny of wires and plugs!

Wireless networks are now widely used including Internet-enabled mobile phones with cellular phone networks and, within buildings, wireless networks such as Bluetooth. These are in addition to the site networks used by academic institutions and large businesses. Wireless routers must be configured immediately for security right after you set up your network. It is important to emphasis that wireless can easily also mean insecure unless users are careful to set systems up correctly.

So, do this right away, as soon as you have got the device running. You need to set a new password for the router and limit access to only those computers on your wireless network.

Informally defined computer networking is the foundation of the Internet. The Internet itself is easier to understand when defined as the set of users, enterprises,and content providers that are interconnected by Internet Service Providers (ISP).

From an engineering standpoint, and please forgive me for being rather techie here; the Internet is the set of subnets, and aggregates of subnets, which share the registered IP address space and exchange information about the reachability of those IP addresses using the Border Gateway Protocol . Computer networks may also be classified according to the network layer at which they operate according to some basic reference models that are considered to be standards in the industry such as the seven layer OSI reference model and the five layer TCP/IP model.

Companies that use their own computer networks must administer complex systems which, once deployed, become vital tools for the continued efficiency of their operations. They employ administrators who focus primarily on the day-to-day operation of networks, while network engineers deal primarily with system upgrades, security testing, and so on.

Given the highly technological nature of computer networks you would have thought that just maintaining and developing these would be hard enough. However, companies also routinely face ongoing challenges with the fight against damaging software, such as malware such as worms, viruses, and spyware.

Computer networking has enabled people to work on the move, and take work home much more efficiently than has ever been possible before. Today’s mobile workforce attach numerous devices to the corporate network that are hard to control from a security policy perspective. It is a common strand that companies that maximize the use of and benefits from the capacities and capabilities of their networks are able to gather, analyze, and disseminate critical marketing information quickly, which can give them an advantage over their competitors.

However, data loss and system downtime can bring any business to it’s knees, so in this area to use the strictly cheapest systems and labor, may be a false economy of the first order. There are many highly trained staff who participate in Microsoft’s certified computer networking courses and qualification. These specialists are more than able to protect your business network day and night. They deliver network support services which include data security, data backup and disaster recovery plans.

1. Message: the message is a generic term that scribes the data to be transmitted. It can be email, webpage, user call, instant message, or any other forms. The message is generated by the end user that needs to make the transmission. This message will be fed to the network later.

Generally, the message is generated using software installed on computer. For example, if the message is email, it will be generated by email programs such as outlook. Also if the message is a web page request, it will be generated by a browser such as internet explorer. It can also be generated by a chatting program is it represents a call by the user.

2. Medium: the medium is the transmission path over which the data will be transmitted. Is is used to connect the end user with the network device or to connect the network devices with each other.

Many types exist for the medium. Mainly it can be wired or wireless medium. The wired medium can be copper or optical fibers. The copper is subdivided into coaxial cables and twisted pairs. The copper wires carry data as electrical pulses while the optical fiber carry data as light pulses. The wireless medium carries data as electromagnetic waves. Each of the above mediums has its own specifications and used according to the application.

3. Devices: there are two basic types of devices in the network: end user devices and network devices. The end user device is considered to be the source of the message. It can be a client computer or an IP phone. The function of the end user device is to send the data to the network.

On the other hand, the network devices are used along with the medium to forward the data generated by the end user device. They are located in between the end user devices and connected between them through the cables.

The main function of the computer network devices is to forward the data to the correct destination based on the address that is send along with the data. The two main devices that accomplish this are the routers and the switches. The router forwards the data according to the IP address while the switch forwards the data according to the MAC address inside the data frame.

4. Rules: the rules are the protocols that used between the end user devices that organize the communication. The two popular protocols are the IP protocol and the TCP protocol. When the end user needs to send the data, it runs a conversation first with the other device according to a set of rules that prepares for the transmission. Each network uses its own protocols set up by the administrator of the network to manage the operations inside the network. Note that this element is a software element and is set up by software programs.
