The Web browser is the most-used kind of software in the world, having become the de facto way that people access the Internet. Today, virtually all computing tasks can be completed in the browser.

Testing browsers can veer from incredibly complex to shockingly simple, depending on what you're looking for and why. At CNET, we prefer a holistic approach to browser benchmarking, looking at a combination of tests that benchmark general browser behavior, as well as several "real-world" tests that look at browser performance in common scenarios.

From the most basic handsets to ultra-advanced smartphones that are essentially pocket computers, mobile phones are complex devices. They reach out to the cloud, surf the Internet, play music, run countless apps, connect to social-networking services, are messaging masters, and, yes, they even make voice calls. … Read more

Much thought goes into evaluating the quality of a given tablet here at CNET. From the way it feels in your hands, to the speed in which you can access your favorite Web site, to the frame rates you can expect when playing games, in the end, all the pieces matter. And while it's difficult to empirically evaluate the feel of a tablet, gauging its performance is a different story altogether.

What follows is our current tablet testing procedure, which consists of a battery life test, and display performance evaluations, plus a few anecdotal speed tests. Expect these tests … Read more

In the networking device category, CNET conducts performance tests only on Wi-Fi routers and power-line adapters. Simply put, these are the two types of devices for which it is easy to measure data rates in repeatable and meaningful ways. For more information on other aspects of home networking devices, check out this series on their basics.

A router is the central gateway of a home network. Not only does it connect all devices together via network cables or Wi-Fi signals to form a network, but also it connects to the Internet via its WAN port, and it shares that connection … Read more

Testing a storage device is more difficult than you may expect. They may not be particularly glamorous, but storage devices serve a vital function in your digital life. Making sure they perform efficiently is important, which is why I wrote this post detailing how CNET tests the devices that we review.

Before I begin, though, it's essential that you have a good understanding of digital storage basics. So click over to read that series if you want to learn more.

There are three types of mainstream consumer-grade storage devices: internal, external, and network. Generally, we test them by transferring … Read more

CNET and car reviews may appear to be an unlikely combination, but new cars have become technology platforms, using electronics to inform and entertain drivers, avoid collisions, and even save fuel.

Since we began reviewing cars in 2004, automakers have increasingly included navigation, Bluetooth phone systems, and advanced technologies for playing digital music files in dashboards. In fact, the latest trend is to give cars complete data connections, letting drivers use online search to find destinations or listen to streamed music from an Internet-based service.

Given our technology focus, CNET reviews cars differently than traditional publications such as Car and … Read more

Microsoft isn't too happy with the results of a recent test that found fault with its antivirus software.

For the second time in a row, the company's Security Essentials failed to win certification from AV-Test, a German-based testing lab that evaluates the efficacy of antivirus products. Out of 25 programs tested, only three failed to gain AV-Test's thumb's up for certification.

Microsoft's Forefront Endpoint Protection, which is geared toward corporate customers, also failed to gain certification.

Microsoft responded to the test via a blog posted yesterday, challenging its findings.

"Our review showed that 0.… Read more

For the second time in a row, Microsoft Security Essentials has failed to be certified as effective by AV-Test.org, an independent testing lab based in Germany.

The lab publishes test results every two months, and the test from November and December 2012 looked at 25 consumer antivirus security programs. Three failed certification: PC Tools Internet Security 2012, AhnLab Internet Security 8.0, and Microsoft Security Essentials 4.1.

This was the second test in a row in which MSE failed to earn certification. … Read more
