Home Networking

Today, more than ever, home networks are easier and less expensive to set up. At times, however, the knowledge needed for building a network is not accompanied by any guidelines on how to secure them. In some cases, the guidelines are simply ignored. No matter what the case, that is a data disaster just waiting to happen.

You may have a thing about being paranoid about security. That is an excessive amount of concern that should be tempered. However, you should have a certain amount of caution. Security is much like medical insurance. You may not need it very often, but when you do need it, chances are you need it badly. If you don’t have it you may face dire consequences.

Wireless home networks are becoming increasingly popular due to their lower cost and flexibility. However, the wireless network is particularly prone to security issues. In theory, someone that has a wireless enabled laptop can just drive by your house, get into your space and tap into your network. It’s not too much of a problem if all they do is steal a little bandwidth. However, if they happen to be malicious and clever, they will be able to implant a virus into your home network without you even knowing it!

Using the Internet has similar risks. However, in a case like that you usually have to download an attachment from someone you don’t even know to get infected. This scenario is easy to avoid. As a rule of thumb, if you do not know who it is from, do NOT open it. It could be a hacker with a virus. However, in the case of a wireless home network, you do not have to take any action to get infected. Even though you may be following good Internet file sharing practices, you are still vulnerable.

Even if you have a cabled network, it is possible for someone to break in while you are away. Most of these incidents will revolve around stealing property. But by infecting a computer a disgruntled employee, an angry person or a party to a lawsuit may use this as a way of getting revenge. What a better way to get revenge than to have your computer crash!

The solution is typically the same in either type of network. Practice the same good habits you use for Internet data sharing and magnify them. You must make sure that each computer on the network has a password that is required in order to gain access to the system. Leaving a system unprotected to just save a few seconds of inconvenience at home will expose your entire network to unnecessary risk.

One thing you want to do is change the password on your router often. The defaults for most of the popular vendors’ products are known by just about everyone who has the necessary skills to do harm. Make it harder for them to inflict damage by following this simple step. Configure your wireless router according to the manufacturers’ instructions in order to prevent unauthorized access. Today, all wireless routers use WAP to prevent drive-by’s from accessing your system.

Most adults today would be astounded by the amount of computer knowledge a teenager has. Most are well meaning, but some young people have not yet learned how to use a home network securely. Some young people can master the techniques, but they do not yet have the common sense or the wisdom to know how to put these techniques into practice.

Treat your home network in much the same way as you would treat your credit cards. You wouldn’t just hand you credit card out to a stranger would you? Moreover, you wouldn’t tell that stranger your password would you? You would be broke in no time! Do not provide physical access or pass out information to anyone that you do not want to have access to it. This is often a short step from having them access your money. It is an even shorter step to your valuable home network as well as your data. For easy loans manage use payday loan

Next Generation Wireless Networks

in the recent past, has become a word synonymous with the cyber world. In simple terms, networking may be defined as interconnection of computing devices in order to share data. A group of computers interconnected by communication channels facilitate sharing of information, the prime determinant of life itself.

Networks are built with a combination of computer hardware and software. Network Interface Cards (NICs), Bridges, Hubs, Switches, and Routers are some of the basic hardware components used to interconnect the key elements of the computer network. Interlinked with the proper communication paths, networks link to other networks and also contain sub networks. The network layer is the platform on which networks are classified. The functionality of the same is based on basic reference models such as the five-layer Internet Protocol Suite (IP). (A protocol is the communication language used by computing devices.)

Computer networks may be classified based on the type of networks, design, mode of connection, and topology. The types of networks are Personal Area Network (PAN), Local Area Network (LAN), Campus Area Network (CAN), Metropolitan Area Network (MAN), Wide Area Network (WAN), and Global Area Network (GAN). Client-server and peer-to-peer are the two types of high-level network design. It is based on the relationship within the elements in a network. Networks can be classified based on the technology, i.e., the computer hardware employed to enable interlinking devices in the network. For instance, Optical fiber, Ethernet, Wireless LAN, HomePNA, or Power line communication are some of the hardware components that are used. Depending on the topology (layout of connected devices), networks are also distinguished such as Bus, Star, Ring, Mesh, Star-bus, Tree or Hierarchical topology networks, etc.

As a proactive tool, network management helps to design, deploy, and maintain processes. Serving as a powerful tool in the telecommunications market, networking is the reason behind the paradigm shift evident in today’s advanced technology offerings. From cables and routers that link devices, to executing commands based on defined set of rules, transmitting of data has been in the process. The fine infrastructure in networking accelerates the development of cutting-edge solutions.

Networking, in the techno-savvy world makes more sense in relating to the masses than the communication methods of the bygone era. The major advantages of network are speed in connectivity and communication, sharing of resources at a secure and reliable level, enhancement of application performance and balancing, and most of all flexibility to access and connect with people. Networking occupies a prominent place in the information superhighway. On a career perspective, according to the Wall Street Journal (2006), 94% of successful job seekers claimed that networking was the reason for making a huge difference in their careers
