When you use the Internet, your computer can be identified by a unique number called an IP (Internet protocol) address. Your computer's IP address is similar to a telephone number that can be tracked, and it can be used to monitor your online activities. However, when you track a computer's IP address, you won't be able to instantly get the location of the owner. Use the Whois database to obtain basic information about a website IP address or Internet service provider.
Active Directory is a service created by Microsoft for Windows servers. It allows centralized network administration and security management. Some organizations create their own applications to help IT departments use Active Directory. Microsoft created Active Directory Service Interfaces (ADSI) to streamline the process, making it easier to use Active Directory, especially when using Visual Basic 6, one of Microsoft's own programming languages.
Protocols are used to transfer data between devices through access system software like TCP and HTTPS. Open and closed protocols control the type of error checking and data compression the system software uses. This functionality also determines how the data sending software will signal that all the data is sent and how the data receiving system signals that it has received all the data. Though similar in function, open and closed protocols are significantly different in how they are licensed and used by developers.
Postfix is a mail server application for Unix computers that manages and automates email tasks on computers used as Web mail-handling servers. While Postfix can handle certain tasks involved with mail filtering, you may want to use another mail delivery agent such as Procmail to handle incoming message traffic.

Although many VirtualBox users have no issues with their IP address working out of the box, you may find that VirtualBox cannot get your IP address. Without the IP address, you cannot access the Internet from your VirtualBox. You can resolve the issue by troubleshooting through each cause of IP problems in VirtualBox.
Migrating Active Directory and its associated domain-name system and dynamic host-configuration protocol servers from old to new hardware is a complicated process that can take several hours to execute. Windows Server 2008 provides a program called dcpromo to facilitate the migration process. Dcpromo creates a new domain controller in the forest and replicates the settings of the old domain controller. After running dcpromo, you must manually transfer the DNS and DHCP configuration data.
A data source name defines a connection to a database from a Windows computer software application. DSNs give you the ability to make a connection between a database and Windows software and use it in your application without manually coding the connection in the software's code. DSNs are standard components used by large companies that develop and/or use custom proprietary software on several computers. Microsoft's .NET developer framework only supports certain DSN types natively without needing to install third-party software such as Oracle or MySQL. The error returned when you do not have the third-party software installed is "Connection string…
Wireless devices and embedded systems have several common requirements, constraints and properties. An embedded system is a software, firmware and hardware combination built into an appliance or device. It makes the appliance smart and autonomous or self-sufficient. A wireless device runs on a combination of microprocessor, operating system and application software that enables it to communicate with a network or another device via electromagnetic waves. If you draw a diagram for features of embedded and wireless systems, the two sets intersect over a large area. The non-common area of the embedded set does not have the constraints and features in…
Several methods convert a file saved in the latex document mark-up language format into an Open Document Text file.

The trivial file transfer protocol, or TFTP, is a file transfer protocol that allows you to transfer configuration files between computers on the same network. The TFTP client that comes preinstalled on every Windows computers is disabled by default, so you must enable the feature before you can use TFTP with any router. With the feature enabled, however, you can use TFTP with your Asus RT-N16 router directly from the computer's command line.
CPI security systems use a variety of sounds to communicate the status of a system function and security breaches. In many cases, the communication is via one or more beeps that go off in a short burst or series immediately, continuously or intermittently until manually turned off. Learning the reasons for these beeps helps you understand and react appropriately to different situations.
For many users, MS-DOS is an operating system of the past. However, it is a useful aspect of PCs even today. The MS-DOS system utility PRINT.EXE lets applications resume other tasks and not worry about the actual printing. Since MS-DOS is a single-user system, programs like PRINT.EXE can slow the computer down if it is also running a multi-tasking multi-user OS. Several utility vendors have developed programs that resolve backward compatibility issues with printing from MS-DOS programs in a Windows environment.
Oracle Database is a data management tool designed for businesses of all sizes and types. It uses the SQL programming language to define its parameters and comes with an SQL command line interface for making these changes. The transactions parameter specifies the maximum number of concurrent transactions. If you want to increase the size of the transactions parameter, you can do so by using the program's Run SQL Command Line tool.
A configuration problem arises when DHCP and PXE are installed on the same server. This technical issue occurs when both the DHCP and PXE services bind to port 67; only one service may access a single port. To resolve this issue, you must configure the server correctly, which eliminates the port conflict.
Subversion files in Windows, with the extension .SVN, help organize projects by tracking current and older versions of your files, including documentation, text, source code and Web pages. Windows stores SVN files in a directory devoted to them. Subversion is designed so that teams can work on project files without losing track of changes, but it also works for one-person projects.
Windows PowerShell is a shell and scripting language that is part of the .NET Framework that uses cmdlet -- "command-lets" -- commands or functions to perform operations. PowerShell has one main date function called "Get-Date" that returns the current date and time. Get-Date has several methods and properties that let you change the date format or extract portions of the date as needed in your script.
The DNS cache stores the IP address of every website you visit. Storing this information where the browser can find it quickly allows faster connections. However, there are reasons to flush your DNS, including protecting your browsing history and helping resolve certain errors. You can flush your DNS in Windows, OS X and Linux using the command prompt.
Having to re-enter authentication information such as usernames and passwords when connecting to networks and websites can be an annoyance, especially if the locations are visited frequently. Windows 7 includes a feature known as the Credential Manager which allows users to securely store login information for automatic entry when visiting specific websites or network locations. Unfortunately, errors sometimes occur which prevent access to the Credential Manager.
If you're considering switching to a digital phone, such as one through your cable provider or a Voice over Internet Protocol service such as Vonage, check with your security system provider before making the change.

The ProCurve is a product line of core switches manufactured by HP. Some basic configuration tasks for the HP ProCurve switch include setting up the switch's host name, primary VLAN, default gateway, and usernames and passwords for the operator (read access) and manager (read/write access) permission levels. The command line provides access to the complete set of configuration options available in the switch. You must have manager level access to make global configuration changes to the switch. Access to the command line interface happens through the switch's console.
Window panels or panes help brighten offices, houses, lobbies and many rooms in nearly every type of building. It's easy to assume that windows are a lighter part of the wall. After all, they do not take up as much space as the walls around them, and windows are thin by design. But architects understand that windows have significant weight of their own, especially thicker window products that may weigh more than the wood walls nearby. This weight needs to be properly measured and supported when constructing a house.
Ensuring that a computer is secure requires more than simply dealing with viruses and outside traffic that may compromise your data. You must provide the proper permissions to people who use the computer on a daily basis. Administrative tools can alter the way a computer runs and the way users interact with computer software and hardware. You may wish to restrict unqualified users from accessing these tools.
Windows Explorer serves as an important piece of Windows' interface, letting you view, manage and navigate the data stored on your computer. Windows Explorer Favorites lets you quickly access the content you add to your Favorites list. If items aren't appearing in your Favorites, something within Windows is either preventing you from adding items to the list or preventing you from seeing its full contents.
Internet Explorer 8 (IE8) uses less RAM on average than Windows, but more intense applications will easily demand more than Windows does. Computer games, for example, use a lot of memory. If you open numerous IE8 tabs, it's definitely possible to use more RAM than Windows. Don't use up too much RAM -- if you run out, your system will perform sluggishly.
An embedded computer system is one you do not normally see. It is dedicated to a single task, such as controlling the engine in a car. This is in contrast with general-purpose computers, which perform many tasks, including word processing, Web browsing and games. The processor architecture, or arrangement of computer elements, is fine-tuned to the task that the embedded system serves.
You must have permissions in MS-DOS to change file attributes or delete the file from the system. You can use the attrib command to change the file attributes. If the file is set as read-only, then you are unable to delete the file. After you change the attributes, you can delete the file.
A ping sends a group of information packets from a computer to find out if another device is available for connection. Cisco produces a wide range of computer hardware and software used for several applications. A Virtual Local Area Network contains a group of computer devices that may not be available for connection. You may not be able to ping all devices associated with a VLAN.
The Windows Explorer, also known as Explorer.exe, is the internal file manager that allows you to view, open and alter files and folders in the Windows operating system. It is an integral part of your computer’s functions and constantly runs, starting the moment you boot up your computer. By itself, the resources that Explorer consumes may vary depending on what the file manager is accessing and what other programs are interacting with it. However, if Explorer is using up too much CPU, this is the sign of an issue you need to troubleshoot.
IFrames function like miniature Web pages that you can resize and place on your main page. You might find iFrames useful for making a page display another website or content from an HTML document residing on your own Web server. When you add an iFrame to your page, that page serves as the parent window and the iFrame becomes its child. If your iFrame cannot access its parent, you will need to modify your code so that it does not violate browser security restrictions.
Microsoft Disk Operating System, or MS-DOS, is an old operating system created by Microsoft for 32-bit computers. The modern Windows Command Prompt tool is actually an MS-DOS command line that enables you to run MS-DOS programs. By default, MS-DOS doesn't allow users to burn CDs or DVDs. However, a free tool enables you to create an image file from a folder and burn that image onto a CD.
