What Is a Web Server? [MakeUseOf Explains]

If there is one thing that causes the most confusion for people that are new to the web design game, it’s the concept of a web server. When most people think of a “server”, they think of a physical machine like a big computer system sitting in some chilled computer room somewhere, or at the very least some computer system sitting in the basement of some hackers house.

So what is a web server? The truth is that a server in this sense is technically software. It’s literally a service that runs on a computer and “serves” information to multiple clients. This process doesn’t require a huge server or even a single PC. A web server (or multiple web servers for that matter) can be installed on a USB using software like XAMPP and others. Read more:

No! This is not happening to you right now! It’s 1:30 AM, you’re almost finished with your huge project due at 8 AM and your computer just crashed and won’t turn on!

Beyond antivirus software: Eclectic PC security tools for system-wide audits | PCWorld#tk.nl_pwr#tk.nl_pwr#tk.nl_pwr#tk.nl_pwr

Welcome to a harsh reality: Relying on an ostensibly comprehensive antivirus suite just doesn't cut it in 2012.

Antivirus software is crucial for combating viruses, malware, and hackers, but simply installing an antivirus program is rarely enough. You should also use strong passwords; keep your system, applications, and browser plug-ins up-to-date; and make sure your firewall is doing its job by blocking all intrusions. Following these extra safeguards can reduce the chances of your PC becoming a Petri dish full of digital contagions.

Luckily, a number of tools and services can simplify all the extra security precautions that modern PCs require. They go above and beyond what's offered in antivirus suites, performing security audits of vulnerabilities that the big-name software packages miss. Here are five to check out. Read more

PC security: Your essential software toolbox | PCWorld

Mobile malware is getting lots of attention these days, but you can’t forget about your PC’s security—after all, you probably still use it to pay bills, shop online, and store sensitive documents. You should fully protect yourself to lessen the chance of cybercriminals infiltrating your computer and your online accounts, capturing your personal information, invading your privacy, and stealing your money and identity.

You need to guard against viruses, of course, but not all antivirus programs catch all threats, and some do better than others. You have to watch for many other types of threats, too: Malware invasions, hacking attacks, and cases of identify theft can originate from email, search engine results, websites, and social networks such as Facebook. They can also come in the form of links or advertisements for phishing and scam sites. But with some education on the topic, and the right tools, you can identify such scams and avoid falling victim.

If your children use your computer, you must also protect against inappropriate content such as violent games and adult sites, and you should monitor communication on social networks. Although the best approach is to keep a close eye on your kids while they use the computer, you can employ tools and services to filter content and monitor their Web usage when you’re not around.

Protecting your data from computer thieves and from people who tap in to your Wi-Fi signal is also important. Encrypting your computer is the only way to ensure that a thief cannot recover your files, passwords, and other data. And unless you password-protect and encrypt your wireless network, anyone nearby can connect to it, monitor your Internet usage, and possibly access your computers and files.

Here are the security threats you should watch for, and the tools you can use to protect against them. Read more
