What is a Hard Drive Almost all desktop computers have a hard drive inside them, but do you really know what they are? Many people when they hear the word hard drive, think that it refers to the computer as a whole. In reality, though, the hard drive is just one of many different pieces that comprise a computer. The hard drive is one of the most important parts of your computer because it is used as a long-term storage space for your data. What that means, is regardless of whether or not the computer is on, or you lose power, the data will still stay stored on this drive keeping it safe. On the other hand, it tells you how important backing up your data is, because if the hard drive malfunctions there is a good chance you will lose it all. A hard drive is an integral piece of equipment for your computer as your operating system and all your data are typically stored there. In the majority of th

There are very little virus that have targeted Linux based operating systems in the past. There for the requirement of a Virus Guard isn't felt badly. But there are Open Source virus guards that are available for download. CLAMTK is one such virus guard and is available for download from http://clamtk.sourceforge.net. I have heard that there is no necessarily to have a virus guard if you are on Linux.There for just enjoy your time with Linux. You are much safe with Open Source than with Bill.

I thought Windows and Linux were enemies. Well, it seems not... What is best, the big old desktop/surface computer or a small 3inch screen of a SmartPhone or PDA? I'd prefer the big stuff that can easily be gripped. I am not alone, I know it when my friends and you guys ask if phone management is possible in Linux. The answer is, very possible. This is very true if you are running Windows Mobile. All what you need is SynCE. Awailable at SourceForge, it makes your life much simple. Just plugin your phone before starting SynCE and you are done. Apart form theat kMobileTools is also a very useful set of tools that you can use to send SMS, call, phone book management and etc. http://www.kmobiletools.org/ http://sourceforge.net/projects/synce/

I just downgraded my internet connection. I just hate it when a p2p application prevents me from browsing the web fast. So let's do something about it wondershaper is an easy to use traffic shaping script that provides these improvements: * Low latency for interactive traffic (and pings) at all times * Allow websurfing at reasonable speeds while uploading / downloading * Make sure uploads don't hurt downloads * Make sure downloads don't hurt uploads official webpage : http://lartc.org/wondershaper about the ubuntu package : http://packages.ubuntu.com/hoary/net/wondershaper /usr/share/doc/wondershaper contains readme files. You might want to read these also. I'm using firestarter together with wondershaper. Nothing has to be changed to firestarter. So here we go : sudo apt-get install wondershaper use ifconfig to determine which of your networkcards is the one that is connected to your modem (and thus

Conky is an advanced, highly configurable system monitor for X based on torsmo.Conky is an powerful desktop app that posts system monitoring info onto the root window. It is hard to set up properly (has unlisted dependencies, special command line compile options, and requires a mod to xorg.conf to stop it from flickering, and the apt-get version doesnt work properly). Most people can’t get it working right, but its an AWESOME app if it can be set up right done. Install Conky in Ubuntu sudo apt-get install conky This will complete the installation Configuring Conky Make a configuration file in your home directory (Ex:-/home/ubuntuadmin) vi /home/ubuntuadmin/.conkyrc Paste the following code into the file and save / exit # UBUNTU-CONKY # A comprehensive conky script, configured for use on # Ubuntu / Debian Gnome, without the need for any external scripts. # # Based on conky-jc and the default .conkyrc. # INCLUDES: # – tail of /var/log/messages # – netstat connections to your compu

If you’ve ever forgotten your password, you aren’t alone… it’s probably one of the most common tech support problems I’ve encountered over the years. Luckily if you are using Ubuntu they made it incredibly easy to reset your password. All it takes is adjusting the boot parameters slightly and typing a command or two, but we’ll walk you through it. Reset Your Ubuntu Password Reboot your computer, and then as soon as you see the GRUB Loading screen, make sure to hit the ESC key so that you can get to the menu. Root Shell – Easy Method If you have the option, you can choose the “recovery mode” item on the menu, usually found right below your default kernel option. Then choose “Drop to root shell prompt” from this menu. This should give you a root shell prompt. Alternate Root Shell Method If you don’t have the recovery mode option, this is the alternate way to manually edit the grub options to allow for a root shell. First you’ll want to make sure to choose the regu

To make a long story short: The Samba project was started in 1992 by Andrew Tridgell. Samba is a set of tools to share files and printers with computers running Microsoft Windows. It implements the SMB network protocol , which is the heart of Windows networking. Samba can be used to: Act as a server for Windows (or Samba) clients: share folders and printers, including PDF pseudo-printers so all the computers in your network may write PDF files Act as a domain controller in a Windows network (authenticating users, etc.) Do some more complex things, such as using a Windows domain controller to authenticate the users of a Linux/UNIX machine Samba is freely available under the GNU General Public License. More information about Samba can be found at http://www.samba.org . Back to top What to install The samba package is a meta-package intended to be installed on servers. Clients do not need this meta-package. It is not necessary for clients to do any of the following: Access shared fol

The best method to reset a BIOS password depends on what BIOS the computer has. Common BIOS's include AMI, Award, IBM and Phoenix. Numerous other BIOS's do exist, but these are the most common. Some BIOS's allow you to require a password be entered before the system will boot. Some BIOS's allow you to require a password to be entered before the BIOS setup may be accessed. The general categories of solutions to reset a BIOS password are: * Using a Backdoor BIOS Password * Resetting the BIOS Password using Software * Resetting the BIOS Password using Hardware * Vendor Specific Solutions for resetting the BIOS Password Using a Backdoor BIOS Password Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time. AMI Backdoor BIOS Passwo

Introduction The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process. An Overview of the OSI Model --> A networking model offers a generic means to separate computer networking functions into multiple layers. Each of these layers relies on the layers below it to provide supporting capabilities and performs support to the layers above it. Such a model of layered functionality is also called a “protocol stack” or “protocol suite”. Protocols, or rules, can do their work in either hardware or software or, as with most protocol stacks, in a combinat
