Do you need Wireless Rounter for your home?


The benifit of using router is not only expand the number of sharing network or internet using. There is some protection between your computers and your broadband for protection. Here's why you need one for safety, plus all the other benefits a router provides.


First, Networking all devices.

The reason to have a router that you have computers, devices and multiple peripherals. The router is the center of interchange communication. The wireless router can handle not only Internet traffic but it has Ethernet switch and an access point(AP) for wireless. The AP is the part that handles all the Wireless LAN (Wi-Fi) traffic and watch for security. A wireless router is muti functions in one device. In non broadband situation, the AP can still get every device on the network communication.


Second, Using as Internet Splitter.

First and foremost, you have multiple devices. They all want—nay, NEED—Internet connectivity. The router is the "splitter" that makes that happens. By plugging the broadband into the WAN port, you can then get Internet out to all the other devices, both wired and wireless.


Third, PC safe guard.

Routers typically have two built in firewalls. The first is simple NAT for network address translation, which isn't so much for protection as it is for simply making the Internet connection work to all your computers. The second is SPI or stateful packet inspection. Most modern routers have SPI, which keeps extra track of data in network packets and makes sure it's kosher (i.e., you requested it), protecting both the router and your computers by filtering out the bad. Note that these are not a replacement for software firewalls on your PC—every computer should have one running. Windows comes with a weak firewall built in, but you can always get a freebie from Comodo.
Other security you get from a router is: limiting a network to just computers you trust with MAC address filtering, secure wireless transmission, parental controls, web site filters, and more.


Forth, Roaming with Wireless

Modern Wi-Fi is the brand name for a technology called 802.11, which comes in many flavors, all with different speeds and ranges. Buy 802.11n products, especially if they're dual-band, and you'll be covered. They're slightly more expensive, but you get what you pay for. In this case, you'll have speed almost as good as a wired network, with extended range. Even the performance is improved in spots where signals used to get hung up. All that means is: you can move around and stay connected, even in your own home or office.


The last, Sharing Connectivity

It's very useful to share with friends. The right router can let you do that with your own Internet connection. You effectively get two networks, one that's just for you and one for guest access. That way outsiders can use the Web and e-mail, but can't see your stuff. Small retail establishments can use this to be a free hotspot for customers. Offices can use it for visitors in for meetings.

Website and Network Monitoring

In today's world, companies are quickly accepted, the Web and related applications, as part of its overall strategy of the company. You will understand that the Internet offers them the opportunity to target a very focused set of customers spread over a very diverse geography.

For a successful presence on the Internet, it is important that the web server and web applications, reliable, scalable and always available, regardless of the volume of traffic on the site.

To do this, you should all hardware and software with the tools to your website, control is usually called stress-Web-based tool. These should ideally be used even before the site is located on the World Wide Web may be able to offer a reasonable estimate of the performance of your website and a company to identify problems before they arise.

These issues could be able to surf the slow response time when opening the page, a limited number of users simultaneously on the Web, or an upper limit on the number of applications processed by the application of the treatment. Based on the results, a webmaster can identify bottlenecks and take corrective action before losing revenue.

What is the test site for stress?

Stress testing site provides performance reports for the various elements. For example, users might complain that your site is taking ages to load for commercial and most of the results of error messages. Using a web stress tool, you can check whether the performance of web servers. To your surprise, the CPU utilization on the server May, only 20%. But if you are also monitoring the implementation of the database you will find already operates at 100% and is the most likely reason for poor performance.

Tools of stress can be implemented as software solutions where the most important elements of the server, how can such as CPU, memory control and uses hard drive. They are built with user-defined reports that are activated when a certain parameter exceeds a threshold defined by the user. For example, you can configure it generates an alarm when the CPU utilization exceeds 80%. While these are useful for identifying bottlenecks in the system, the results on the Web server limits are linked to the internal network.

Why Stress Monitoring Network?

If the goal is the entire planet, or even across the country re-examines an entity on its website and applications of loads of stress from various locations around the world. The Web server must have a reasonable return, in which the customers are located. In such a situation is the software solution unlikely to meet the needs of society.

Organizations should use a tool for monitoring the external web site stress to give detailed reports on the performance on the servers that were tested in different positions. The results of these tests can help to refine the settings of your provider and to optimize server performance. In addition, infrastructure external evidence of stress and the monitoring of different network, enter the Web server, in order to invite such as routers, firewalls and leased lines, the connection to back-end.

Dotcom-Monitor, then load stress testing tool provides customers test agents of stress in different countries like USA, UK and Germany. This service provides performance data on the website of these and other locations around the world.
