Social networking is a phenomenon born of the Internet and interactive computing, derived from the need to communicate and form social bonds. Social networks often rely on relationship-forming mechanisms such as "following" or "friending" to increase user engagement with the system. How these networks of friendships form, how relationships within the networks work and how relationships or clusters of relationships are maintained can be tracked, in part, with detailed statistical analysis.
CentOS includes a graphical interface to configure networks on your computer. You can also configure networks through the command line. With the default CentOS tool, you can manage your Ethernet and wireless connections. Advanced settings include managing hosts and DNS configuration. CentOS allows you to save and restore your network configuration as well.
PERT and CPM charts visually illustrate the tasks and dependencies of large projects using a flowchart-like diagram. Both techniques use similar approaches; PERT (Program Evaluation and Review Technique) was developed by the U.S. military while CPM (Critical Path Method) was developed in private industry. Several software products can be used to help create these charts, but whether involving computer or paper and pencil, the process remains the same.
A virtual private network is made up of a VPN server, client and connection, and a tunnel. The VPN server is the infrastructure used to enable components to connect to a private network. The VPN client is the program that provides the interface to manage the connection. The VPN connection manages data encryption. The tunnel is the segment of the network that holds the data. Setting up a packet filter on an existing VPN server adds additional protection to the network, preventing the server from sending or retrieving data packets to or from certain networks or ports.
When someone shares a folder using Microsoft Exchange, colleagues using Microsoft Outlook may use it to help share and organize information. However, if you're using Microsoft Entourage, shared folders may not appear automatically in your Inbox. Viewing a folder depends on how the folder was shared, server settings and your permissions for viewing the folder.
Underwater lights are commonly used in pools as a decorative element, as well as a way to provide a safe environment for nighttime swimming. The lights fit into enclosures that are built into the perimeter walls of the pool and run above and below the water. Fiber optic lights give off weaker electrical pulses of light and therefore are considered safer to use over traditional halogen lights.
When you install a new network for an organization, there is usually a set date by which the network needs to be operational. Meeting that target date, regardless of the organization size or the network size, takes a great deal of planning before the installation even begins. A large part of that planning is the establishment of a network deployment timetable. With a properly developed deployment timetable in place, you cannot only ensure the network is installed in time but also that the installation process interrupts current business activities as little as possible.
Point-to-Point Protocol over Ethernet (PPPoE) is a process in which one computer virtually dials another computer. A "WAN" refers to a wide area network. A WAN miniport is a virtual device that certain software programs use to establish network connections, and it is commonly used for dial-up connections. When moving over to a LAN connection, a message such as “Error 678: The remote computer did not respond” may appear when you try to connect to the network. This means that the connection to the server failed.
High-definition video provides a clearer and more defined picture than the consumer digital video often found on standard DVDs. When streaming HD video, you need to stream it at a rate that's high enough to provide the full content contained in the HD video to view the stream in full high definition. Home networks are better suited for this type of streaming than the Internet because they can often support the large bandwidth and connection speeds required to stream large amounts of content.
Unmanaged clients are computers that fall outside the particular information technology management system applicable to a group of computers within an organization. In terms of anti-virus and security systems, the organization does not manage updates, scans and reports for these computers centrally. On a broader basis, an unmanaged client is any device that may connect to an organization's networks but whose security status and operating details are not known. Organizations typically restrict access for such devices because they represent potential risks for network security.
Electronic Data Interchange (EDI) Value-Added Networks, more commonly known as VANs, date back to the 1980s and those now almost unimaginable years before the Internet. Originally consisting of secure phone lines used to transfer important or confidential data, VANs have since evolved to incorporate Internet functionality, but continue to provide similar services, including data transfer, storage, encryption and format conversion. Depending on the nature of your e-commerce business, a VAN may be a good choice for you.
Ubuntu comes with tools you can use to test your network connections, including a ping tool. If you've lost the ability to ping in Ubuntu, fixing the problem depends on how you're using ping. An inability to ping might also mean that your computer can't connect to the remote computer you're attempting to ping.
Many software programs take advantage of the Internet by keeping important data and information stored on a server that can be accessed by users from multiple computers if they need to use the program. In order for these programs to work properly, information or settings changed on one computer must be synchronized with the information stored on the program server. Error 10061 occurs when there is a problem with program synchronization
High availability is crucial for ensuring that problems with an SAP server do not affect client machines or users. A sure way to achieve this is by incorporating clustering, load balancing and failover services in your network mix. Clustering increases the number of SAP servers in your network, load balancing spreads the workload among the available servers and failover services transfer the workload from a failed to a working server in the event of a problem. SAP Central Services, or SCS, is an essential component in an SAP clustered environment.
WAN Miniport (IP) is a simulated device that is not an actual piece of hardware that can be removed. This virtual device is used by device drives to connect to a network. Windows needs the WAN miniport (IP) to perform wireless networking, PPP0E and Remote Access Service. Microsoft recommends that the user does not uninstall this device. If the drivers for this device are corrupt, then Internet access may be blocked, Virtual Private Networking disabled and RAS unusable.
The Dell Wide Area Network (WAN) Miniport controls the Point-to-Point over Ethernet (PPPoE) access to a network. WAN Miniport manages the data streaming through the Network Interface Card (NIC). Error code 39 states: “Windows cannot load the device driver for this hardware. The device driver may be corrupted or missing.” This stops whatever task that was running that triggered the error.
Guild Wars, the award-winning, online, role-playing game requires a solid, high-speed Internet connection to work properly. In online games, the quality of your connection is often dictated by your ping. The better your ping, the better a gaming session you will enjoy, and the better you will be able to coordinate with your party. A poor ping can muck up your Guild Wars experience. In addition to this main meaning, a ping in Guild Wars is also a feature of the compass, as well as a way of sharing information on your build.
The Spanning Tree Protocol is a computer networking protocol with a design that resembles a tree diagram with linked branches. The STP is composed of network bridges linking network segments and ending in network ports. A network port changes roles and states depending on what function the port is performing, and whether it is waiting for data information, sending or receiving data.
An ad-hoc network allows you to connect an iPhone to your computer. The setup process is relatively simple but sometimes complications can occur related to software incompatibility and improper configuration. When the ad-hoc connection is not set up correctly, your iPhone does not recognize or connect to the network. Ad-hoc networks generally represent a temporary type of network, and the risk of a security breach increases with this type of network.
The GPRS network on your mobile phone connects you to the Internet for browsing and downloading. Each wireless provider requires its own network profile, and if the profile is configured with the wrong details, Internet connectivity will be lost. Most users will never need to change their GPRS settings, but consulting with your wireless provider proves vital when configuration becomes necessary.
The print spooler loads documents and files into memory for printing. The spooler is controlled by the print spooler service of Windows computers and is set to automatically start by default. If the print spooler crashes before you login, your documents fail to print. To fix a print spooler crash and print your documents, use the following troubleshooting steps.
Applications establish network connections using numbered ports. Server software, such as game servers and file-sharing programs, requires that a port can receive incoming connections from the Internet. Many of these applications check that their ports can receive incoming connections, ensuring that the network is configured correctly. An error message indicates that the program won’t work correctly until its port can receive incoming connections.
Wide Area Network is a telecommunication network that is used to cover a broad area. The WAN miniport is a software adapter used by the operating system to access the WAN. Most of the time, the WAN miniport is used to connect to the Internet through a Point-to-point protocol over Ethernet connection. In essence, to connect through the WAN miniport, you must have a valid PPPoE connection set up. When you initiate the connection on a Windows operating system, you briefly see an "Connecting Through WAN Miniport" message.
When a folder in an email account that you access via a Web-based Microsoft Outlook "exchange" server is shared, the folder does not belong wholly to you or to any other individual who shares the folder. Only the network administrator can delete folders that are shared among multiple individuals on the network.
Microsoft uses two different types of network and security models to protect user information. They are NET security and SharePoint Server models. Both models use codes or protocols to identify a user or an app location and then grant or deny access to the user or app.
Both Macs and PCs have a large variety of hardware components inside of their respective computer cases; when you hear an odd noise, such as a gentle chirping coming from your PC or Mac, you'll want to ascertain whether the sound is coming, as it most likely is, from your computer's hard drive.
When new internetwork standards arise, companies may find it difficult and costly to upgrade the infrastructure in order to ensure compliance with the new standards. To keep businesses running smoothly, most standards will allow provide a transition period in which existing technology can operate in conjunction with the new standard. As implementation of IPv6 networks occurred, Microsoft developed an interface called the Intra-site Automatic Tunnel Addressing Protocol, or ISATAP, to help facilitate the transition between existing IPv4 networks to the new IPv6 networks.
When running modules on your Drupal site, it is important to keep your modules updated to ensure that each module functions efficiently and effectively.

From its initial appearance in June 1998 onward, Gigabit Ethernet and the equipment it uses to function have enjoyed increasingly wider acceptance. As an industrial-strength version of the common Ethernet standard, Gigabit Ethernet is a low-cost, high-speed and easy-to-implement network solution suitable for not only business and commercial use but increasingly for home networks as well. Among the items of equipment necessary to run a Gigabit network is a small form-factor pluggable transceiver module, commonly known as a Gigabit SFP.
Hubs enable you to expand the number of external devices connected to your iMac and extend the distance at which you can place your peripheral components. You can connect a hard drive, optical drive, camera, camcorder or scanner to a Belkin FireWire hub. With a Belkin USB hub, you can add drives, plug in a graphics tablet, access a flash drive or add a printer. If your iMac doesn't recognize your Belkin hub, check these possibilities for the cause of your problem.
Access control lists and firewalls provide differing levels of network security and can work together to prevent unauthorized and unsolicited traffic from entering an enterprise's network. An ACL provides simple packet filtering, examining individual data packets to determine whether to allow them network access. While ACLs provide fast data flow processing with a low demand on network resources, they lack the advanced security features firewalls offer, making relying on ACLs alone for network security a risky proposition.
You can set up your own local area network at home using modem cables. Often called Ethernet or CAT5 cables, they're the same cables used to connect a single computer to a router or modem. Windows 7 computers have a built-in networking capability that you can use to connect two computers. Once you have established your LAN, you can share files between two computers or even use one Internet-enabled computer to provide an Internet connection to the other.
The tools that you can use to perform a Wi-Fi site survey will provide a signal-to-noise ratio, and that defines the power of the primary signal as compared to the rest of the background noise on that radio channel. However, if you want to determine the accuracy of your Wi-Fi network tools, you'll need a consistent signal generator that will provide a defined amount of noise, so you can compare the reading from the network tool to the actual SNR.
Underwriters Laboratories Inc. is an independent company that conducts safety and performance testing on a wide variety of products, including wire and cable. The company's website notes that in 2010, there were 66,932 manufacturers worldwide producing UL-certified products. You can tell if a network cable has been rated by UL by looking for the "UL" designation on the side of the cable, with additional details on the tag the cable came with.
A virtual private network allows users to connect to a local area network from remote locations using the Internet. A VPN tunnel connects two LANs together using the Internet. Many routers have VPN capability but none are specifically described as "VPN routers." Although the term "dynamic" appears in the jargon, it does not describe a particular type of VPN. Manufacturers, engineers and administrators use the term "dynamic" to describe different features.
A wide area network is a telecommunications network dispersed over a large geographical area. Public and private organizations use this type of network to provide information and services to users accessing it from multiple locations. A WAN miniport driver allows an Internet-enabled device to establish an active connection with the network.
Ping is a network utility that measures the speed and reliability of a connection from endpoint to endpoint. There is no specific Ping protocol; instead, the utility relies on the Internet Control Message Protocol, or ICMP, and every computer connected to the Internet has to implement this protocol.
In computer terminology, LDIF stands for LDAP Data Interchange Format. An LDIF file is a directory service file that can be transferred between servers. Whenever information is transferred automatically between computers, the sender and receiver have to have a common format defined for the record structure. There is no point sending a message or a file written to a secret standard, since the receiver of such a file would not be able to break down the contents into meaningful data. This is why international standards defining neutral formats are published freely. The LDIF format is defined by an openly available…
Outputting your PC's display on your Sony Bravia is a bit more complicated than just connecting the two devices. You have to make sure the settings on the two devices are adjusted to work with each other and that all of the hardware is in good working order. Also, sometimes the PC's display may not output simply because of a minor software glitch that can only be resolved be reconnecting the devices or restarting one of the devices.
Outdated drivers, speaker conflicts, and incorrect microphone software settings are common Vista and microphone echoing problems. Webcams with built-in microphones may also cause echoing. Your audio devices, related software and Vista are likely compatible. Some audio devices just can't share the limelight at the same time.
