If you have ever had problems with the speed of your laptop, you would know how frustrating it can sometimes be especially if you do not know what to do about it or what you have tried to do did not work. There are several things you can do to make a laptop run faster and this article would show you some of them.
The first way to do this is to get a very good anti-virus and anti-spyware and do a scan of your computer to make sure there is no spyware or virus on your computer that you did not know about. The reason why this is important is because spyware and viruses cause harm to your computer and they can also affect the speed of your system. There are many good anti-spyware and anti-virus available on the internet, some of which are free while some require you to pay a one time fee or an annual fee to be able to use them.
You can also make your system work faster by doing a regular maintenance of your computer and some of the things you should do include deleting our temporary internet files and cookies and emptying your recycle bin. You should also try to delete all files, folders, programs and software which are on your computer which you no longer use or which you do not need and the reason why this helps is that it helps to free up space on the hard disk of your laptop which can make your computer work faster. You should try to do theses activities weekly, bi-weekly or monthly depending on the age of your computer and how much you use your computer.

When shopping for a wireless router, the first detail that you’ll most likely look for is its signal strength. Indeed, you wouldn’t want any dead spot ruining your 50-gigabyte download. The good news is many of today’s routers can easily blanket your house with Wi-Fi. They’re already so powerful and efficient that your next door neighbor could effortlessly pick up signals from your overzealous Wi-Fi distributor.
Unless your neighbors are as trustworthy as your dog, sharing wireless Internet with them may not be exactly a wise move. For one thing, having too many computers sipping through your router may slowdown your surfing speed. Some ISPs are also setting limits on monthly bandwidths, so you might end up hitting your quota in just a week if you continue to be a good Samaritan to them.
But the strongest argument against sharing Wi-Fi with neighbors is the possibility of data theft. The fact that they could access your router or wireless Internet means that they could also very possibly access your computer, too.
This doesn’t mean that you should buy routers that have weak signals. If you want to rival Starbuck’s Wi-Fi strength, then by all means buy the best router that your budget allows. Just make sure that you limit the number of persons who could have access to your personal network. You could easily do this by setting up a password for your router. Another method by which you could restrict or regulate access is by pre-defining the hardware which could access your network.

Ever been at a friend's house and wanted to show off a photo you left saved on your home computer? Ever wanted to check from the office that your daughter's doing homework and not instant messaging with friends at home? Ever need to grab a file on your home hard drive when you're miles away? An age-old protocol called VNC and some free software lets you control your home computer from anywhere.
In this tutorial, we'll set up a VNC (Virtual Network Computing) server on your home computer, which will let you connect to your desktop and drive it from any Internet-connected computer.
Notes and warnings: Running a server and opening up a port on your home computer to the Internet is a risky undertaking. Make sure your computer has all the latest security patches, has been checked for spyware and viruses and that you're using strong passwords. The VNC protocol is not inherently secure. This how-to assumes you're comfortable with basic networking concepts. If you're scared off by the fine print, check out an easier alternative [1] to VNC. Still with me? Read on.
The Virtual Network Computing (VNC) protocol remotely controls another computer over a network. Think of it as a window into your home computer's desktop from any other computer. Your key presses and mouse clicks get transferred over the network and happen on the remote computer in real time, and anyone at the remote computer can watch the action as it happens.
A few things you can do with a VNC server running at home:
Start a downloading a large file, like a movie, in the morning so it's there when you get home in the evening
Search your home computer's IM logs, address book or file system for important information
Help Mom figure out why Microsoft Word doesn't start without having to go to her house (even though Mom would like to see you more often)
Control a headless (monitor-less) machine like a media center or file server in another room in the house from the laptop on the couch
VNC requires two components for a successful connection: the server on your home computer, and the viewer on the remote computer. Let's set up each component to get going. Here's how.
Step 1. Install the VNC server.
Windows users: TightVNC is free Windows VNC server and client software. TightVNC is a nice choice because it also allows for file transfers and high compression levels for slow connections. Download TightVNC from here and run the installation on your home computer. Start the server, and set a password for incoming connections.
TightVNC can be set to run as a Windows service, which means your Windows usernames and passwords can be used to authenticate on the VNC server connection. Be sure all your Windows passwords are set and strong, and that any passwordless guest accounts are disabled.
Mac users: OSXvnc is a free Mac VNC server. Download, install, set up a password and start the server.
If your VNC server is connected directly to the Internet, it is now listening for Internet requests [2] on port 5900, VNC's default port (which is also configurable). Visit WhatIsMyIP from your home computer to determine its IP address and write it down.
Step 2. Install the VNC client.
On the remote Windows computer, also download and install TightVNC, but this time, start the viewer, NOT the server. If you're on a Mac, download the free Chicken of the VNC Mac viewer to connect to your home PC. Enter your home computer's IP address [3] and password to connect.
Here's a screengrab of a VNC connection to my Windows PC from my Mac. Click on the image to see a larger version.
And that's that! You're virtually sitting at your home desktop from anywhere in the world.
A few extra VNC tips to chew on:
For slower network connections, set the compression to "best." The window image quality will be lower, but the connection response will be snappier.
Bring a VNC viewer with you on a USB memory stick so you don't have to download and install on every computer you want to use to connect to your server.
Avoid having to install a server on Mom's computer; email her the 166K self-extracting SingleClick UltraVNC server for your next tech support phone session. More on SingleClick in an upcoming Lifehacker feature.

FOOTNOTES:
[1] LogMeIn is a web-based application that also provides this remote desktop control and may be a better option for some folks. I prefer VNC because it's more of a challenge and doesn't require third party intervention.
[2] If your home computer is behind a home network router with a firewall, remote computers will not be able to connect. You must open up a port on your router's firewall and forward requests to it to your computer, a how-to that's beyond the scope of this article but will be covered in an upcoming Lifehacker feature is covered in the Lifehacker feature How to access a home server behind a firewall.
[3] Alternately, you can enter your home computer's domain name. For more information on setting that up, see previous Lifehacker feature Assign a domain name to your home server. This way, when connecting using the VNC viewer, you can enter an address like mycomputer.dyndns.org instead of an IP address.
