How Firewall Works? Firewalls may decide to allow or block network traffic between devices based on the rules that are pre-configured or set by the firewall administrator. Most personal firewalls such as Windows firewall operate on a set of pre-configured rules which are most suitable under normal circumstances, so that the user need not worry much about configuring the firewall.

How Proxy Server Works? whenever the client connects to a web proxy server and makes a request for the resources (in this case, “Sample.html”) that reside on a remote server (in this case, xyz.com), the proxy server forwards this request to the target server on behalf of the client so as to fetch the requested resource and deliver it back to the client. An example of client can be a user operated computer that is connected to the Internet.

Cool your machine. If your computer suddenly starts operating very slowly, check to see if the case feels overly hot. Especially in hot climates, make sure that the computer has adequate airflow around it. Overheating causes myriad difficulties and the computer bays in most work desks do not provide sufficient airflow. Overheating can result in genuine problems. It can harm key inner parts, including the processor, battery, and hard drive. Running at high temperatures for a lengthy amount of time can cause drive failure. Hard drive failure rates increase somewhere around 20% and 30% for each 10 degrees above recommended working temperatures.

Do regular maintenance. For example, CCleaner can delete temporary or potentially unwanted files left by certain programs. The program also includes a registry cleaner to locate and correct problems in the Windows registry. Periodically conduct scans for viruses, spywares and the registry errors.

Defrag the hard drive. Defragmentation is one of those words that sends most user’s heads spinning but it’s very easy to understand. Often, a tech will leave this function running after they’ve completed servicing a PC. The software for doing this is included in Windows and it only takes a button press to start it. Basically, the function cleans up the hard drive so that files are more quickly accessed.

Delete browser history. Your browsing history records the website addresses that you visit, temporary Internet files, cookies, and information that you have entered in certain websites such as your name and address. Cookies are tiny data files that store information about your custom website settings. Cleaning them out often can help free up space and improve speed.

Uninstall unused programs. If you have decided to stop using a program, always remove it from your Add or Remove Programs function in the Control Panel. Force Uninstall: When you uninstall any program, there will be some files left over after that, so you need to force install that program.

Delete temporary files. Physically cleaning out the temporary filw organizer is a fundamental maintenance step. Check to see whether the Windows XP Disk Cleanup utility is doing its job or not. Deleting temporary documents is a simple task that can help free up drive space and keeps your PC free of document mess.

Ensure that there is always some space in the hard drive. Keeping junk files in the computer can decrease the speed dramatically. Disk space is required for installing new files. Always clean your history, recycle bin and temporary files

2 Keep the system clean. Filling up almost the entire hard drive with what amounts to junk will cause your computer to crawl. Over time, this compromises the function of the computer. While you can increase the RAM and maybe upgrade the CPU and GPU for the best performance, cleaning out the system is a good starting option, as junk has no place on your computer.

How to Improve Computer Speed Performance When your once new computer starts to become the "new clunker" in your life, it's time to revise what junk and viral matter are slowing down the cogs in your machine. Over time, computers do slow down if care is not taken to address the problems that mount up. Each is easily taken care of, provided you know how and why. What is Slowing Down Your Computer? 1 Be aware that the majority of the machine issues are the aftereffect of infections, spywares and the registry over-burden. If care is taken to do regular upkeep checks, this can be balanced out and problems dealt with and removed. Windows PCs tend to slow down as applications are introduced and utilized. Whether you are utilizing a processor, a spreadsheet, surfing the web, playing games or whatever else, hard drives loaded up with makeshift documents that don't generally get evacuated when no longer required will slow down considerably. Hard drives can succumb to wear and tear over time as well.
