How to Secure Your Wireless Network
Wireless technology has revolutionized home networking in the past few years. However, because of increasing signal strength, wireless signals will often extend farther than the boundaries of your home and may be picked up by other computers—sometimes as much as two or three blocks away! Because of this, it’s essential that you secure your wireless network properly. The following are tips on how to do this.
The first and easiest task is turn firewalls on. This includes computers on the wireless network as well as on your router. Almost all computers with wireless capabilities will have the option to turn on and off a firewall. Make sure that each computer has its own unique user name and password.
All wireless routers, via a standard IP address, allow you access and set up the equipment. Here, you enter your network address and other important information. Be sure to change the default username and password that allows you to access this page. And don’t forget to write down your changes!
Every computer accessing a wireless router will have a MAC address. One technique to secure your network is to only allow computers with certain MAC addresses to access the network. If you only have a few computers, this shouldn’t be a time consuming process.

First Steps in Computer Networking — Get it Together
Computer networking can be a tricky. With different devices and protocols, things can get mixed up rather quickly. However, learning the basics should be manageable for the average computer user. Below explains the first networking building block—connecting computers to the network.
Until recently, the most common way to connect computers directly was with an Ethernet cable, or an Ethernet cable via a hub. However, wireless technologies make connecting even easier. Instead of a cable, think of a wireless network as having invisible, or radio signal, cables.
To connect computers in a wireless network, even if you don’t have an internet connection, can be done very easily—no router required. If the computers have Wi-Fi devices, whether built in or added, you can create an “ad-hoc” wireless network by configuring the computers to ad-hoc mode.

Common Types of Computer Networks
Computer network design can range from simple to very complex. Networking can be as simple as connecting two computers, or a computer and a printer, while more complex networks can involve the connection of millions of computers and devices.

7 Rules for Social Networking Marketing Effectiveness
Social networking is rapidly becoming the most preferred Web 2.0 marketing tool. If you are engaged in selling your products or services online, there is plenty you can do with social networking sites to promote your business.
However, the possibilities are accompanied by inevitable pitfalls. Here are a few things to keep in mind in order to raise your effectiveness when using social networking sites.
Rule #1 – One site or many: While many organizations prefer to maintain their presence on several social networking sites, it can take up considerable amount of time as well as staff resources. Determine the amount of time you can spend updating your profile on each site. It’s far more effective to spend extra time and energy maintaining a high profile on one, well-chosen site rather than spend precious hours juggling different operating platforms on too many different sites.
If you do choose to maintain a presence on multiple sites, make sure you assign a full-time staff to regulate your various profiles. This could include posting comments on other member’s pages, inviting other people to become friends, or accepting other friend’s requests. In the absence of regular care, your web page is sure to languish.
