Users often think of computers as monolithic machines that contain all the necessary parts to run smoothly and efficiently, and that these parts are all made for that common goal. However, computers are often built from disparate add-ons and enhancements. It is up to the computer's processor and operating system to handle the computer so that it behaves as a smoothly operating machine. To do this, the operating system, such as Linux, and the processor use a series of "interrupts," which the hardware uses to signal that it requires processor time, or that it has finished its task.
PdaNet, an application compatible with all Android devices, enables mobile phones to connect to Bluetooth dial-up networks and connect to desktop, laptop or netbook computers via USB tethering. As of the date of publication, Android devices can connect to a Bluetooth DUN via Ubuntu Linux using PdaNet, but USB tethering is not yet supported. Before Ubuntu 10.10, pairing Bluetooth devices with the operating system was a somewhat complicated process, but the OS system now offers graphical user interface support for Bluetooth networking.

The Dell OptiPlex GX260 was designed for use with Microsoft Windows, but the desktop computer can run with some Linux distributions. Although the OptiPlex GX260 meets all of the minimum requirements to run Red Hat Linux 7.1, the computer's default hardware configuration may prevent Red Hat Linux from properly displaying video. You can circumvent video-related issues by upgrading the basic input/output system -- an internal software that controls the operation of hardware -- and selecting the appropriate options during the installation of the OS.
System security is the biggest concern at the operating system and database server levels. A database administrator uses the functionality provided by a relational database system to implement security and user-authentication methods. After the preliminary stage of user authentication, the database server must check to see if the user has permission to perform a certain task, such as creating databases and database objects. The database administrator grants or denies privileges to or revokes privileges from the appropriate user accounts. If you cannot create a database, you are using a server login that is not granted a “dbcreator” or higher role.…
Tweetdeck is a Twitter app that allows users to follow several Twitter accounts in a single application window. It can be run with Safari and Adobe AIR Web browsers on a Mac.

For instance, digital video recorders like TiVo or Foxtel iQ contain microcontrollers that use embedded Linux to store and retrieve video on hard drives, USB or Secure Digital drives.
A virtual local area network, OR VLAN, provides the ability to create multiple LANs within a single physical network. To set up DHCP for the VLANs, first set up the network interfaces for each VLAN and then establish the DHCP settings for each VLAN. When you configure DHCP, treat each VLAN as though it were a separate physical interface on the machine, just as a DHCP client does when requesting a new address.
The Mac OS X 10.6 Snow Leopard version of the Mail application allows users to set up an account to send and receive Internet Message Access Protocol (IMAP) and Post Office Protocol (POP) emails. Whenever you launch the application, Mail imports the mail from your email's IMAP or POP server. An error, however, sometimes causes this mail import process to freeze up, rendering the application useless. If you are having problems importing mail into the Snow Leopard Mail application, there are a number of steps you can take to fix the issue.
While installing Ubuntu, the Ubuntu installer configures the hardware settings to work on your computer. If something goes wrong, the installer hangs and doesn't progress further. The problem can range from issues with your copy of Ubuntu to problems problems with manually installed drivers for connected hardware.

Iptables is a command that controls the firewall built into the Linux 2.4 kernel and newer versions. Iptables contains a number of chains -- for example, each packet leaving the system goes through the OUTPUT chain -- and each chain can contain any number of rules. Rules can accept, reject, drop or forward network packets that they match. The standard iptables command only applies to IPv4 traffic. Use the ip6tables command to control firewall rules for IPv6 traffic.
