Understanding Ad Servers

An ad server is simply a computer or web server. This server is backed up by a database, which stores the advertisements and used them in internet marketing. The web server delivers those advertisements to website visitors. The web server content is constantly updated, so that the ads displayed web page or website contains new advertisements when the page is refreshed or visited by a user.

  • Ad serving: Ad serving is the service and technology, which places ads on websites. The purpose of the ad serving technology companies is to deliver the targeted ads based on the website visitor’s interest. These companies provide software to the advertisers and websites to serve ads, different advertisement campaigns progress monitor, count the ads, and choose ads that make advertiser or website most money. These will helps for an advertiser to determine Return On Investment (ROI) on a particular website.
  • How it works? When a visitor visits your website, it will display ads along with the content. If you are subscribed to a third party ad server, they place the ads. Means content is from your site and ads are from other website or server. Browser assembles all the information that fed from different sources because both website’s original content and the ads appear on the same page. To assemble the ads correctly, website directs the browser to collect the data from different website’s ad server.
  • Functionality: The functions of the ad servers are uploading rich media and advertisements, trafficking advertisements according to different of business, targeting ads to different content and users, optimizing and tuning based on results, reporting interaction metrics, post impression activities, post click, clicks and impressions. The other advanced functions are frequency capping which makes users to see the ads for a limited time as well advertisers can also set a frequency cap on spending of money and limit their ads. Sequencing ads provides users to see messages in a specified order. It is also called surround sessions.
  • Optimization and targeting: One aspect of this technology is semi-automated and automated. Which means targeting, placement, optimizing bid prices or other characteristics? Significant methods in ad serving technology include behavioral targeting, contextual targeting and creative optimization.

An ad server can be run by third party or locally or remote ad servers. Remote ad servers serve the ads different domains, which are owned by different publishers. The ads delivering by these are from a central source, so the publishers and advertisers can track their online advertisement distribution. It is single location for distribution and rotation of the ads across the web. Local ad servers are run by a single publisher. It can allow serving the ads to that publisher’s domains.

Understanding WAN Optimization

Wide area network is a type of computer network which covers a broad area. It is used to connect all the types of networks, so that people and computers in one area can communicate with the computers in other area. Each organization requires a private WAN, tailored according to the needs of the organization.

WAN optimization products, help in accelerating a broad range of applications accessed by distributed enterprise users by eliminating redundant transmissions, staging data in local caches, compressing and prioritizing data, and streamlining chatty protocols. WAN optimization also avoids packet delivery issues which are very common in WAN environments. WAN optimization helps in interconnecting the branch offices, vendors, partners and mobile workers. Generally an organization uses WAN optimization to cut down the costs and for reducing the network traffic.

Application performance management (APM), is the system which monitors and manages the performance and service of the software applications. There are two ways in which the application performance is measured. First is the resource used and the second is response time. Application performance management is related to the measuring of end user experience, which is the major criterion for measuring the performance of an application in the production.

Generally in WAN optimization Application Performance Management is used to measure the increase in the performance level and decrease in the reaction time.

WAN Optimization Accelerates Application Performance

Faster application performance ensures that a business effectively renders quality services to its employees and customers. WAN optimization is essential to businesses that are using network applications at its headquarters to stay in touch with branches at remote locations through WAN. WAN optimization enhances the application performance by techniques like bandwidth management, caching, compression, and Protocol optimization and significantly accelerates application performance.

Benefits:
Improves Productivity
Slow speed of application performance really hampers the employee productivity and customer satisfaction. Use of WAN optimization techniques accelerates the applications over the WAN, speeds up the data transfer and reduces the end-user application response time. This in turn makes transactions faster thereby leveraging the employee productivity. WAN optimization reduces the time taken to complete repetitive operations and helps in increasing employee productivity.

The employees waiting for long time to get a transaction done or download a file can not give prompt service to the customers and it results in unsatisfactory customer experience. By eliminating the network problems and reduced throughput, the remote employees can access the network applications that are installed on other locations at a faster rate. Accelerating the applications over the WAN also helps the mobile workers making it easy for them to cater their services to consumers.

Reduces Bandwidth Cost
Using WAN optimization techniques like bandwidth management/QoS, caching, compression, and Protocol optimization can significantly reduce the usage of bandwidth which in turn pulls down the network costs.

  • In Bandwidth Management, limits are set on network applications as to how much bandwidth they can use. This ensures maximum utilization of existing bandwidth by critical applications without providing additional bandwidth, saving considerable amount of money.
    In Caching, the copies of important files are stored in multiple locations. The users need not have to download these large files every time thereby reducing the bandwidth utilization.
  • Protocol optimization decreases the transmission delays thereby increasing overall speed of transmission and transaction response.
  • Compression techniques help to reduce size of the data thus saving time of transmission. Compression helps to send data in a faster way thus increasing reducing load on communication links.
  • Compression and caching together help keep the communications link uncongested and reduces queuing delays.

All these factors reduce bandwidth usage which in turn reduces cost. WAN optimization allows users to access WAN applications at speeds similar to a LAN.

WAN optimization accelerates application performance by eliminating issues like redundant file transmissions, chatty protocols, network latency, packet loss etc. WAN optimization ensures consolidation of IT infrastructure of the business at remote locations thereby ensuring higher productivity at remote offices. Using WAN optimization, the businesses can reduce remote office infrastructure cost by effectively centralizing applications, data storage, and server at data centers.

WAN optimization techniques increases transaction speed, improves productivity, and reduces bandwidth cost enabling businesses to be competitive and focus on newer markets. WAN optimization implementation helps businesses to get excellent ROI on their investments by reducing bandwidth costs and improving overall productivity.

Pros And Cons Between Analogue And Digital Electronics

Generally the information is encoded differently in analogue and digital electronics, the method they process a signal is consequently different. All operations that can be performed on an analogue signal such as amplification, filtering, limiting, and others, can also be duplicated in the digital domain. The first electronic devices invented and mass produced were analogue. The use of microelectronics has reduced the cost of digital techniques and now makes digital methods reasonable and cost-effective. There are all some main difference between analogue and digital electronics:

Noise: Because of the way information is encoded in analogue circuits, they are much more susceptible to noise than digital circuits, since a small change in the signal can represent a significant change in the information present in the signal and can reason the information present to be lost. Since digital signals take on one of only two different values, a noise would have to be about one-half the magnitude of the digital signal to cause an error; this property of digital circuits can be exploited to make signal processing noise-resistant. In digital electronics, for the reason that the information is quantized, as long as the signal stays inside a range of values, it represents the same information. Digital circuits use this principle to regenerate the signal at each logic gate, lessening or removing noise.

Precision: A number of factors influence how precise a signal is, mainly the noise present in the original signal and the noise added by processing. See signal-to-noise ratio. Fundamental physical limits such as the shot noise in components limits the resolution of analogue signals. In digital electronics additional accuracy is obtained by using additional digits to represent the signal; the practical limit in the number of digits is determined by the performance of the analogue to digital converters, since digital operations can usually be performed without loss of precision.

Design Difficulty: Digital systems are much easier and smaller to design than comparable analogue circuits. This is one of the major reasons why digital systems are more common than analog. An analogue circuit must be designed by hand, and the process is much less mechanical than for digital systems. Also, because the smaller the integrated circuit (chip) the cheaper it is, and digital systems are much smaller than analog, therefore a digital system is cheaper to produce than an analog.

Ie 8 Gets Hacked Inspite Of Microsoft’s Lauds

Microsoft is releasing Internet Explorer 8, Mozilla is into releasing Fennec and Google into New beta of Chrome browser. With all these big browsers with big brands entering into the market, a question arises how safe are they?

You know how hacking has become a serious problem. Amid of these it is not only viable to use the older browsers but also to use the newer ones’ without knowing their security levels.

When Microsoft was marketing its new Internet Explorer 8, the main features it lauded of were ActiveX lockdowns, Automatic crash recovery, InPrivate browsing and Filtering, XSS filter, Data Execution Detection, etc. The words are big, but did not work when they actually had to. It was hacked within few minutes, in 10th annual CanSecWest Conference. So you know the new IE 8, with all its big security features, is still vulnerable. And the vulnerability is said to increase by adding new add-ons to the browser.
