Email Archiving And How To Sell It?

Even with under 50 percent penetration, the Email archiving market is starting to shake out. Two vendors are trying to build new identities for themselves, to establish new market niches and change from being the number 8 product in a 22 player field and be thought of as first, second or third in the market they define for themselves. Metalogix went the value route, reducing the price of their Professional Archive Manager for Exchange (PAM) to $15/user while releasing a new version. ZL Technologies decided to sue Gartner for continuing to put them in the niche category of their Magic Quadrant report.

Strengthen Your Security With The Fortify 360

Source code analysis is a fundamental part of a complete application security process. It finds flaws and vulnerabilities in application code that could be exploited by attackers. A critical component of source code analysis is tracking and remediating the flaws and vulnerabilities uncovered during analysis. Fortify's 360 Server is a repository for all the results and remediation activities that accompany an analysis of source code. While the 360 Server doesn't perform the source code analysis, it does accept uploads from other Fortify products in the 360 suite that do. Organizations can also take advantage of its service-oriented architecture to integrate with third-party code analysis software.

Understanding Private Cloud Storage

Mention cloud storage to most IT professionals and they think of Internet services like Amazon S3 and Nirvanix that store your data in their data centers. But a storage cloud doesn't have to be public. A wide range of private cloud storage products have been introduced by vendors, including name-brand companies such as EMC, with its Atmos line, and smaller players like ParaScale and Bycast. Other vendors are slapping the "cloud" label on existing product lines. Given the amorphous definitions surrounding all things cloud, that label may or may not be accurate. What's more important than semantics, however, is finding the right architecture to suit your storage needs.

Ten Ways The Cloud Will Reshape Voice

There is considerable discussion about the oncoming impacts of cloud computing and how it will reshape (or eliminate) the enterprise data center. But until recently, there has been relatively little discussion about how cloud technologies will impact telecommunications, or specifically enterprise voice.

Personal Area Network (PAN)

A personal area network (PAN) is a computer network used for communication among computer devices (including telephones and personal digital assistants) close to one's person. The devices may or may not belong to the person in question. The reach of a PAN is typically a few meters. PANs can be used for communication among the personal devices themselves (intrapersonal communication), or for connecting to a higher level network and the Internet (an uplink). Personal area networks may be wired with computer buses such as USB and FireWire. A wireless personal area network (WPAN) can also be made possible with network technologies such as IrDA, Bluetooth, UWB, Z-Wave and ZigBee.

Wireless Communications 2009

Wireless communications is a rapidly growing segment of the communications industry, with the potential to provide high-speed high-quality information exchange between portable devices located anywhere in the world. Potential applications enabled by this technology include multimedia Internet-enabled cell phones, smart homes and appliances, automated highway systems, video teleconferencing and distance learning, and autonomous sensor networks, to name just a few. However, supporting these applications using wireless techniques poses a significant technical challenge. This course will cover advanced topics in wireless communications for voice, data, and multimedia. We begin with a brief overview of current wireless systems and standards. We then characterize the wireless channel, including path loss for different environments, random log-normal shadowing due to signal attenuation, and the flat and frequency-selective properties of multipath fading. Next we examine the fundamental capacity limits of wireless channels and the characteristics of the capacity-achieving transmission strategies. These strategies are typically not practical. Thus, our next focus will be on practical digital modulation techniques and their performance under wireless channel impairments, including flat and frequency selective fading. The next part of the course is spent investigating techniques to improve the speed and performance of wireless links. We will investigate the design and performance of adaptive modulation and diversity techniques to compensate for flat-fading. Three techniques to combat frequency-selective fading are then examined: adaptive equalization, multicarrier modulation, and spread spectrum. We will also study the multiple access capabilities of spread spectrum with multiuser detection. The course concludes with a brief overview of wireless networks, including multiple and random access techniques, WLANs, cellular system design, and ad-hoc network design. Applications for these systems, including the evolution of cell phones and PDAs, smart homes and appliances, sensor networks, and automated highways and skyways, will also be discussed.

Television Network

A television network is a distribution network for television content whereby a central operation provides programming for many television stations. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (e.g. the BBC, NBC or CBS) evolved from earlier radio networks. In countries where most networks broadcast identical, centrally originated content to all their stations and where most individual transmitters therefore operate only as large "repeater stations", the terms television network, television channel and television station have become interchangeable in everyday language, with only professionals in TV-related occupations continuing to make a difference between them. Within the industry, a tiering is sometimes created among groups of networks based on whether their programming is simultaneously originated from a central point, and whether the network master control has the technical and administrative capability to take over the programming of their affiliates in real-time when it deems this necessary—the most common example being breaking national news events.

Telecommunication Network

A "Telecommunications Network" is a network of telecommunications links and nodes arranged so that messages may be passed from one part of the network to another over multiple links and through various nodes. Telecommunications network links (including their endpoints or "nodes") may in turn be built out of hierarchical transmission systems.

Examples of telecommunications networks are:

* Computer network
* the Internet Network- The internet network is a global ‘network of networks’. The internet is connected via an Internet Service Provider (ISP) and then becomes part of a network. This network then connects to a larger corporate network that interconnects with several other similar networks through Network Access Points (NAPs).
* the Public switched telephone network
* the global Telex network
* the aeronautical ACARS network

Computer Network

The System in which two or more Computers are interconnected and they communicate freely, that system is called "Computer Network". Computer networks can also be classified according to the hardware and software technology that is used to interconnect the individual devices in the network, such as Optical fiber, Ethernet, Wireless LAN, Home PNA, Power line communication or G.hn. Ethernet uses physical wiring to connect devices. Frequently deployed devices include hubs, switches, bridges and/or routers. Wireless LAN technology is designed to connect devices without wiring. These devices use radio waves or infrared signals as a transmission medium. ITU-T G.hn technology uses existing home wiring (coaxial cable, phone lines and power lines) to create a high-speed (up to 1 Gigabit/s) local area network.
