Tips For Buying The Right Laptop Computer

5 Tips For Buying The Right Laptop Computer Want to buy a Laptop?? It's easy to be intimidated by all the laptop models on the market today. There are literally dozens and dozens in every price range. The key to finding the right one for you is to step back and consider exactly how you plan to use your laptop. When you define what you need before you go shopping, buying the right machine becomes much easier. Here are 5 basic factors to consider: 1. Size In the world of mobile computing, size definitely matters. The size of a laptop affects two key areas: portability and display size. If you're always on the go and will be using your computer only in short bursts, a so-called ultralight will save you some shoulder strain. On the other hand, if you're going to spend hours in front of your laptop, a larger display may be in order. Today, some laptop displays exceed 17 inches, rivaling the display size of many desktop systems. The down side is that these monsters can easily weigh three times as much as an ultralight. 2. Hard Drive Speaking of size, what about the size of the hard drive? One way to approach this issue is to ask yourself the following question: Will this be my primary computer, or will it supplement my desktop system? If the former, you should look for a bigger hard drive - 60 GB or more. If the latter, you may be able to make it with a 20-30 GB hard drive. But even this isn't absolute. If, for example, you plan to copy a huge MP3 library from your desktop system to your laptop to make your music library portable, you'd be well advised to err on the side of too big. 3. Memory In determining the right amount of system memory, or RAM, take a look at the ways in which you intend to use your laptop: If your needs are somewhat mundane - email, spreadsheets, word processing, etc. - 256 MB, 512 MB, 1 GB or 2 GB of RAM should be plenty. This is a common configuration for many laptops, so it means you probably won't need to spend extra for more RAM. On the flip side, if you're an aspiring mobile digital photographer or videographer, you should stuff your laptop with as much RAM as it can hold. In fact, exactly how much RAM your laptop can hold may in part drive your purchase decision. Applications for editing and manipulating multimedia content are notorious resource hogs. 4. Network Connections Thanks in no small part to the Internet, computing in the 21st century reliesheavily on being connected: Connected to the Internet, connected to a corporate network, connected to a wireless network, connected to a home network, connected to an online service. Your life will be easier if you buy a laptop that includes built-in means to connect to them all. 5. Price If you're considering a laptop, you're probably wondering how much money you'll need to spend. A few years ago, you'd be hard-pressed to find one for under $2,000. Today, there are plenty of laptops to be had for under $1,000. What's more, most of the major manufacturers offer a variety of financing options. Laptop prices have come down, to be sure. However, a laptop still represents a fairly major purchase for most people. If you take the time to search for a laptop that meets your specific needs, you should get many years of use and enjoyment from this important investment. ****************************************************** ..::Click Here to visit my Blog::.. ..:: Download Free Softwares::.. ..:: Download Free E-Books::..

How to Stay Safe and Secure Online | 10 tips to Stay Safe and Secure Online

10 tips to Stay Safe and Secure Online The Internet can be a dangerous place. While you're enjoying the convenience of online shopping, Internet banking and subscription websites, nasty people lurk around every corner. Hackers, fraudsters, identity thieves and many others would love to get hold of your personal details. And what stands between you and a security disaster? Your password. Just 8 little characters long, it's your last line of defense online. So here are 10 tips for choosing and using bullet-proof passwords that will protect you from harm: Tip 1 - Avoid the obvious Passwords based on personal details are too easy to guess. Avoid using names, places, favorite sports teams, or “password". Tip 2 - Make it non-dictionary One option a thief might try to crack your password is a brute-force dictionary attack. So choose something that you won't find in any dictionary. Tip 3 - Use the full 8 characters The more characters a password contains the more secure it becomes, so fill that password field to the max. Tip 4 - Mix the case Deter thieves further by using a combination of upper and lower-case letters. A mIXeD cAsE password adds another layer of protection and is ever harder to guess. Tip 5 - Include non-alphabetic characters Adding numbers and non-alphabetic characters (like a hyphen) to your password makes it less likely to be cracked than something purely alphabetic. Tip 6 - Don't write it down This should be obvious but it's amazing how many scraps of paper surround the world's PCs. Tip 7 - Assign a different password to each login id If thieves get hold of your password, they'll try it in every online system available. Use a separate password at each website and you won't have all your eggs in one basket. Tip 8 - Employ a password manager Remembering multiple secure passwords can be challenging. Specialist software like http://www.robo-form.com manages your passwords securely and automates the login process. Tip 9 - Logout when you're done Always hit the logout button when you've finished using a secure site like online banking. Tip 10 - Close that browser Web pages and passwords can be cached in the browser, so close down your browser window for added security. Follow these simple common-sense tips and you'll enjoy greater online security while benefiting from the many advantages the Internet has brought. ****************************************************** ..::Click Here to visit my Blog::.. ..:: Download Free Softwares::.. ..:: Download Free E-Books::..

Some Linux Commands

Here are some basic Linux commands. Some are well known and some aren't. I am not a Linux Wizard...far from it...but I am learning some basic linux commands and thought I would share some with other newbies so they to can get more familiar with the terminal command line. These work on my Mandrake 8.1 system. xkill Kills a running program exit Exits the terminal reboot Reboots the system halt Shutsdown the computer startx Starts xwindows from terminal man man(command)shows help files info info(command) shows help files --help (command)--help shows help files su Allow you to login as Super User ls "Lists" the contents of the directory pwd Displays "present working directory" cd cd (name) change directory TO:(name) mkdir mkdir (name) Makes new directory rmdir rmdir (name) Removes directory clear Clears the terminal window date Displays current date and time cal Displays a calander uptime Displays time since last reboot df Displays the disk usage on partitions du Displays disk usage of directory id Displays your identification to system groups Displays groups of current user ulimit -a Displays users limits uname Displays name of machine logged into who Displays "who" is logged on the system w Similar to "who" wall Sends message to all logged in users top Displays cpu processes memory etc ps Displays current running processes ---------------------- RPM's Mandrake and RedHat Check if installed already rpm -q To Install the rpm rpm -ih To Update a program using an rpm rpm -Uvh ---------------------- Bored try this: apropos file List tons of file commands ----------------------- Many of the commands listed above have options that can be added to change the output of that command. To see what they are do a : man (command) and it will show you the options. The command line is hard to learn to use at first ..... really hard for us converted MS$ users :) but it is worth the effort. To start a program "like Opera" type the name at the command prompt: $ opera There are many file commands that I didn't list due to the complexity of them. Read up on them and you can harness the power of your computer from the command line! I have to go read now :)
