Products in the Internet Media sector [done by MSRSAS] 3. Actors in the Value Creation Chain of Internet Media 3.1. Web Content development Content development is the process of researching, writing, gathering, organizing, and editing information for publication on web sites. Web site content may consist of prose, graphics, pictures, recordings, movies or other media assets that could be distributed by a hypertext transfer protocol server, and viewed by a web browser. 3.1.1. Web Hosting A web hosting service is a type of internet hosting service that provides individuals, organizations and users with online systems for storing information, images, video, or any content accessible via the web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center. In the most general sense, a web site requires: hardware, software, a connection to the Internet and an administrator. The web hosting can be either of the following, Shared Hosting: An Internet Service Provider (ISP) manages the Internet connection, hardware and software for a web site. Co-location Hosting: It is essentially access to a steel server locker and a high-speed, guaranteed bandwidth, local area network connection. Managed Hosting: At this level of service the ISP or MSP will acquire the hardware and software needed for a site as well as provide administration services. Managed hosting can include performance and security testing, monitoring, reporting and networking services. Development Hosting: It brings all of the value of Managed Hosting while adding full application support. It is required to test or track (monitor) how end-users interact with a website or web application. Website monitoring is often used by businesses to ensure that their customers are able to access their online applications and perform actions such as searching, online shopping, checking an account balance, or simply researching. By monitoring website and web application performance, IT Departments or Network Engineers hope to avoid downtime and keep their applications running. Commonly measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to gain popularity. Website monitoring can be done from both inside and outside of a corporate firewall. Traditional Network Management solutions focus on inside the firewall monitoring, whereas external performance monitoring will test and monitor performance issues across the Internet backbone and in some cases all the way to the end-user. External performance monitoring is also known as end-user monitoring or end-to-end performance monitoring. 5/12 Website monitoring service can check HTTP pages, HTTPS, FTP, SMTP, POP3, IMAP, DNS, Telnet, SSL, TCP and a range of other ports with great variety of check intervals from every 4 hours to every one minute. Typically, most website monitoring services test your server anywhere between once-per hour to once-per-minute. Website monitoring services usually have a number of servers around the globe - USA, Europe, Asia, Australia and other locations. By having multiple servers in different geographic locations, monitoring service can determine if a Web server is available across different Networks worldwide. The more locations the better picture on your website availability 3.2. Web Hosters and Service Providers An Internet service provider (abbr. ISP, also called Internet access provider or IAP) is a business or organization that offers users access to the Internet and related services. Many but not all ISPs are telephone companies. They provide services such as Internet transit, domain name registration and hosting, dial-up or DSL access, leased line access and colocation. Internet hosting services run servers, provide managed hosting, and include the Internet connection. Generally, an ISP charges a monthly access fee to the consumer. The consumer then has access to the Internet, although the speed at which this data is transferred varies widely. Internet connection speed can generally be divided into two categories: dialup and broadband. Dialup connections require the use of a phone line, and usually have connections of 56 kbit/s or less. Broadband connections can be either ISDN, Broadband wireless access, Cable modem, DSL, Fiber Optics, Satellite or Ethernet. Broadband is always on (except ISDN that is a circuit switching technology), and varies in speed between 64 Kb and 20 Mb per second or more.With the increasing popularity of file sharing and downloading music and the general demand for faster page loads, higher bandwidth connections are becoming more popular. A Virtual ISP (vISP) re-sells to the general public Internet access purchased from a wholesale ISP. The vISP's role is to provide any services beyond Internet connectivity, such as e-mail, web hosting, and technical support. The vISP must perform all authentication and accounting functions necessary to provide access and then bill their users for it. This model allows for larger ISPs to increase returns on their investment into what is generally a geographically large, high capacity network, a network which smaller ISPs as customers of the larger ISP can use to serve customers in locations that would previously have been unavailable to them. A Web host leases space for your Web files on their server, which has a direct connection to the Internet whereas an Internet service provider maintains a server that is directly connected to the Internet. This chapter covers the details of various players and process involved in the web hosting and service process. 6/12 3.2.1. Web Developers This is a person or company that develops websites. A web developer handles all aspects of programming and scripting for a website. This includes adding pictures, client text, creating hyperlinks and implementing the site. 3.2.2. Web Designers This is a person or company that designs web sites. They are usually the graphic artists. Web Designers produce a mockup of a page in a graphics application. Once the client has approved the design, the designer sends it to the Web Developer The terms Web Designer and Web Developer can be used interchangeably, as the companies who work as web designers are capable of working as web developers also and vice versa. According to present Internet industry scenario, Web development incorporates all areas of creating a Web site for the World Wide Web. This includes Web design (graphic design, XHTML, CSS, usability and semantics), programming, server administration, content management, marketing, testing and deployment. 3.2.2.1. Graphic Designers A graphic designer works for the appearance of the website. This can include the plan, layout at the basic level and further covering cognitive and perception aspects to see the ease of use. Graphic design work also includes the aesthetics, visibility colour etc of the website. They use a variety of graphics and layout computer software to assist in their designs. Designers creating Web pages or other interactive media designs also will use computer animation and programming packages. Computer software programs allow ease and flexibility in exploring a greater number of design alternatives. 3.2.2.2. Photographers/ Videographers Photographer works for bringing the images to be displayed on the website whereas videographers is involved I shooting videos. The necessity and other tricks and techniques of these professions make them important in the Internet value chain. 3.2.3. Content Authors Writing and preparing content for the Web requires a different approach from writing and preparing content for print documents and publications. In addition, writing copy for the Web that grabs attention and gets the desired results takes special skill and attention, whether it is an attempt to sell products or services at a business or commercial site or if desire to let people know the latest at your personal site. The resources below are annotated links to highly authoritative articles, tips and information specific to content writing, development, and preparation for Web sites. Therefore there is a close network between writers, editors, content developers, and publishers. 7/12 3.2.4. Advertising Agencies Advertising is the paid promotion of goods, services, companies and ideas by an identified sponsor. Marketers see advertising as part of an overall promotional strategy. Other components of the promotional mix include publicity, public relations, personal selling and sales promotion. The agencies in involved in the publicity of the website and related media play a significant role in the value chain for Internet. 3.2.5. Affiliates An affiliate is an entity with a relationship with a peer or a larger entity. These affiliates are involved in a no risk partnership in an order to promote the other companies website and products forming a smaller domain of advertisers. 3.3. Web Hosting A web hosting service is a type of internet hosting service that provides individuals, organizations and users with online systems for storing information, images, video, or any content accessible via the web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center. In the most general sense, a web site requires: hardware, software, a connection to the Internet and an administrator. The web hosting agencies vary in the service they provide. The First and most basic is web page and (small) file hosting, where files can be uploaded via FTP or a Web interface. The files are usually delivered to the Web "as is" or with little processing. Which is sufficient only for personal home pages. The Second type is a complex site, which calls for a more comprehensive package that provides database support and application development platforms. These facilities allow the customers to write or install scripts for applications like forums and content management. The Third category is that the host may also provide a Web interfacing for managing the web server and installing scripts as well as other services like e-mail. Lastly some hosts specialize in certain software or services (e.g. e-commerce), used by larger companies to outsource network infrastructure to a hosting company. In information technology, a server is a computer program that provides services to other computer programs (and their users) in the same or other computers. The computer that a server program runs in is also frequently referred to as a server (though it may be used for other purposes as well). For procuring server space we need to work through a server space provider. A server space provider is an individual, company, or organization that provides storage space on a server for Web pages, usually for a charge. Some independent access providers and 8/12 online services provide a limited amount of free space for Web pages (for example, one megabytes of hard disk storage). Note that not all access provider offer server space. And many server space providers do not provide access. Server space and access are two different services. Access provider – An access provider is any organization that arranges for an individual or an organization to have access to the Internet. Access providers are generally divided into two classes: Internet access providers (ISPs) and online service providers (OSPs). 3.3.1. Domain name Registration This is a process in which a unique domain name is selected and registered by a user, giving the user the right to use that domain name for their web site. DNS (Domain Name System) Initially the Internet was built on the notion that any computer on a global network can be identified by its numeric Internet Protocol (IP) address. But since people, the primary user of the Internet, a more people-friendly naming system called the Domain Name System (DNS) was invented. Domain Name A domain name is essentially a signpost on the Internet. People register domain names in order to 'stake a claim' to a particular name -- whether for business or personal reasons. Domain Name Registrar A registrar or "Domain Name Registrar" is any entity, organization like 1stDomain.net that acts on behalf of a registrant regarding domain name requests or modifications. Domain Parking Registrars require the use of name servers or hosts for every domain registered. In other words, every domain name has to be linked to a name server for it to be valid. Domain Registrant A registrant is the person or company who registers a domain name Domain Registry the organization responsible for the administration and maintenance to a top-level domain database is known as the registry. Domain Name Transfer The term 'transfer' refers to when Domain names are sold to another individual or organization or the name of a company might change. The Registrar has a process by which permission from the old owner is required to hand over control to the new owner. 3.3.2. Security and Maintenance Information travelling on the Internet usually takes a circuitous route through several intermediary computers to reach any destination computer. The actual route the information takes to reach its destination is not under our control. As the information travels on Internet computers, any intermediary computer has the potential to eavesdrop and make copies. An intermediary computer could even deceive and exchange information by misrepresenting itself as an intended destination. These possibilities make the transfer of confidential information such as passwords or credit card numbers susceptible to abuse. This is where Internet security comes in and why it has become a rapidly growing concern for all who use the Internet. For security there is a need of Routers: While using a computer at work, or with the advent of cable modems at home, it might be required to place computers behind a router that uses NAT. NAT enables multiple computers to access to the Internet over a single high-speed link. 9/12 3.3.3. Website Marketing Internet marketing is a component of electronic. Internet marketing can include information management, public relations, customer service and sales. Electronic commerce and Internet marketing have become popular as Internet access is becoming more widely available and used. Well over one third of consumers who have Internet access in their homes report using the Internet to make purchases. Internet marketing is associated with several business models. The main models include business-to-business and business to consumer (B2C). B2B consists of companies doing business with each other, whereas B2C involves selling directly to the end consumer. Search engine advertising could be further classified as Advertising based on a keyword search search, Advertising based on content context. 3.4. Service Provider’s at National and Regional Level The service providers provides connections and the services related previously there used to be two Connection Options network connection, allowing users of local area networks (LANs) to go online through their school or workplace systems, and dial-up connections through a modem and phone line. However, new connection options allow for greater speeds and flexibility, they are: Cable Internet these systems allow your computer to connect to the Internet through the same cable that carries your TV signal. Satellite connections Allow you to download Internet files via a satellite connection. Integrated Services Digital Network (ISDN) is a type of digital phone line that can transmit data many times faster than a conventional modem and phone line. Wireless connections Pagers, cellular phones and personal digital assistants (PDAs) now allow varying levels of Internet access, from notification of E-mail to limited Web connections. National ISPs are usually established businesses with years of experience. They have the resources to invest in the latest technology and high-speed connections to the Internet. Offering local access numbers all over the country. Some large ISPs don't focus enough on customer service and support. They may be less responsive to small business customers. Many Regional ISPs are just as established as their national competitors. They tend to offer more responsive, personalized service and support. You should be able to find one that provides local access numbers where you need them. 3.4.1. Internet Browsing A web browser is the software program you use to access the World Wide Web, the graphical portion of the Internet. At the top of the screen, it has a bar for typing in Web addresses, a small search panel and a row of buttons -- the typical tools for common Web-surfing activities. Forward, back, home, reload and stop can all be found in this basic setup. 10/12 Internet explorer is currently the most widely used web browsers in the world, making it the prime target for phising and many other possible attacks. This has caused some users to switch to different browsers, such as mozilla, firefox, operand Netscape. 3.4.2. Firewall Developers A firewall is simply a program or hardware device that filters the information coming through the Internet connection into the private network or computer system. Firewalls use one or more of three methods to control traffic flowing in and out of the network: Packet filtering - Packets (small chunks of data) are analyzed against a set of filters. Proxy service - Information from the Internet is retrieved by the firewall and then sent to the requesting system and vice versa. Stateful inspection - A newer method that doesn't examine the contents of each packet but instead compares certain key parts of the packet to a database of trusted information. 3.4.3. Users The Internet presents a unique problem for surveying. At the heart of the issue is the methodology used to collect responses from individual users. Since there is no central registry of all Internet users, completing a census, where an attempt is made to contact every user of the Internet, is neither practical nor feasible financially. As such, Internet surveys attempt to answer questions about all users by selecting a subset of users to participate in the survey. This process of determining a set of users is called sampling, since only a sample of all possible users is selected 4. Technologies used in the Value Creation Chain of Internet Media Networking hardware includes all computers, peripherals, interface cards and other equipment needed to perform data processing and communications within the network. The some of the hardware equipments are File Servers, Network Interface Cards, Ethernet Cards, Local Talk Connectors, Token Ring Cards, Switches, Repeaters, Bridges, and Routers. All user of computers connected to a network is called workstations. A typical workstation is a computer that is configured with a network interface card, networking software, and the appropriate cables a network is simply a group of two or more Personal Computers linked together. Many types of networks exist, but the most common types of networks are Local-Area Networks (LANs), and Wide-Area Networks (WANs). In a LAN, computers are connected together within a "local" area. In a WAN, computers are farther apart and are connected via telephone/communication lines, radio waves, or other means of connection. Networks are usually classified using three properties: Topology, Protocol, and Architecture. Topology specifies the geometric arrangement of the network. Protocol specifies a common set of rules and signals the computers on the network use to communicate. Architecture refers to one of the two major types of network architecture. 11/12 Network Technologies, provides associated services including product installation, software maintenance programs, parts repair, remote and on-site technical assistance and customer training. The Group's product brands include Service Creation Manager(TM) platform, Intranet telephony platform and network management systems based on simple network management protocol. Network Equipment Manufacturers market products and services through direct and indirect sales channels and under collaborative government contracting and subcontracting arrangements. 5.
