Linear, Non-Linear, In-banner, and in-text video ads are described below:- i) Linear Video Ads:  More commonly known as pre, mid and post-roll ads, linear ads take over the full video player space. They're linear because they run in line sequentially with the content, for example, a pre-roll will appear as (ad-video); a mid-roll will be (video-ad-video) and a post-roll will appear as (video-ad). Linear ads can be 15 or 30-seconds long and do not allow for fast-forwarding through the ad. OR, Linear Video Ads are the most iconic and widespread formats of in-stream video advertising. Just like in the traditional TV broadcasts, they are cutting into the main video and playing in-line with the rest of the content. Linear ad interrupts the primary video and occupies the entire video-played space. It can encompass the interactive component or work with a companion ad. ii) Non-linear Video ad: runs parallel to the video content so the users see the ad while viewing the content. Non-linear

Revenue model A firm's revenue model describes how the firm will earn revenue, generate profits, and produce a superior return on invested capital. capital. We use the terms revenue model and financial model interchangeably.  There are many different e-commerce revenue models that have been developed followings are the types of revenue models: ➤Types of Revenue Model the advertising model,  the subscription model, the transaction fee model, the sales model, and the affiliate model. i. The advertising model:   In the advertising revenue model, a company that offers content, services, and/or products also provides a forum for advertisements and receives fees from advertisers. Companies that are able to attract the greatest viewership or that have a highly specialized, differentiated viewership and are able to retain user attention are able to charge higher advertising rates.

There are four major characteristics of e-commerce: i. Ubiquity ii. Global Reach iii. Information Richness iv. Information density v. Personalization and Customization vi. Interactivity i. Ubiquity: Because E-Commerce is ubiquitous, the market is able to extend its traditional operating hours. Online stores never close, it is available everywhere at any time. Ubiquity lowers transaction costs for the consumer/buyer. For example, if the user is at an outstation, he also can through www.acer.com get information about the product. ii. Information Richness: Advertising and branding are important parts of commerce. E-Commerce can deliver video, audio, animation, etc. to introduce products. Individuals may see information richness if a post contains a video related to a product and hyperlinks that allow him/her to look at or purchase the product and send information about the post via text message or email. An example is the richness is can make the websites become attract people to browse.

Secured Electronic Transaction (SET) Protocol Secure Electronic Transaction is an open-source encryption and security specification designed to protect credit card transactions on the internet.

Secure Electronic Transaction is also called SET. i) Purchase Request:   Before the purchase request exchange begins, the cardholder has completed browsing, selecting, and ordering. The end of this phase occurs when the merchant sends a completed order to the customer. All of the preceding occurs without the use of SET. The purchase request involves 4 messages:- Initiate Request Initiate Response Purchase Request  Purchase Response When the merchant receives the Purchase Request message, it performs the following actions: It verifies the cardholder certificates by means of its CA signatures.

Security mechanisms used to secure e-commerce systems E-Commerce security is the guideline that ensures safe transactions through the internet. It consists of protocols that safeguard people who engage in online selling and buying goods and services.  The different types of security measures of e-commerce systems are given below i) Cryptography:  Cryptography is a science that is used to hide the semantic meaning of a text using some mathematical module. They give the power to hide the information during the network traverse or storage. Many methods are 16-bit,32-bit, 128-bit, and 256-bit encryption or many algorithms like AES, DES, Message Digest, RSA, Quantum encryption, etc. In this form, Original messages are converted into non-readable forms. ii) Hash Function:  Hash functions are an important type of cryptographic algorithm and are widely used in cryptography such as digital signature, data authentication, e-commerce, e-cash, and many other applications. The purpose of the use of

 The barriers to the complete implementation of private industrial networks are:- One barrier is that participating firms are required to share sensitive data with their business partners up and down the supply chain. This is a huge corporate mindset change because what was previously considered proprietary and secret must now be shared. Furthermore, in the digital environment, it can be difficult to control the limits of this information sharing. Information that a firm willingly gives to its largest customer may wind up being shared with its closest competitor. Other barriers include difficulties in integrating private industrial networks into existing ERP (enterprise resource planning) systems and EDI (electronic data interchange) networks. Most ERP systems were not designed initially to work with extranets or even to be particularly Internet compliant; they were based on business models that use entirely internal business processes. Furthermore, changes in corporate culture and att

 CPFR (collaborative resource planning, forecasting, and replenishment)  CPFR (collaborative resource planning, forecasting, and replenishment) involves working with network members to forecast demand, develop production plans, and coordinate shipping, warehousing, and stocking activities. The goal is to ensure that retail and wholesale shelf space is precisely maintained.  The benefits it could achieve for private industrial network members are that hundreds of millions of dollars of excess inventory and capacity could be wrung out of an industry.

The difference between an industry consortium and a private industrial network are:- Private industrial networks, which presently dominate B2B commerce, are Web-enabled networks for coordinating trans-organizational business processes (collaborative commerce). These networks range in scope from a single firm to an entire industry. Although the central purpose of a private network is to provide industry-wide global solutions to achieve the highest levels of efficiency, they generally start with a single sponsoring company that “owns” the network. This differentiates private markets from industry consortia, which are usually owned collectively by major firms through equity participation.

 The main reason is they failed to attract enough players to achieve liquidity. That is, the number of buyers and sellers in the market, the transaction volume, and the size of the transactions were insufficient to sustain a profit.

The objectives of a private industrial network may include to: • develop efficient industry-wide purchasing and selling business processes • develop industry-wide resource planning to supplement enterprise-wide resource planning • create increasing supply chain visibility so that the inventory levels of buyers and suppliers will be known to the participants • achieve closer buyer-supplier relationships, including demand forecasting, communications, and conflict resolution • foster operations on a global scale • reduce industry risk by preventing imbalances in supply and demand, including developing financial derivatives, insurance, and futures markets

The anti-competitive possibilities inherent in Net marketplaces include: • The possibility that they may provide some firms with an ideal platform to collude on pricing, market sharing, and market access. For example, in a Net marketplace owned by large industry players, owner-members could collide with one another on the prices they are willing to pay for inputs. • The sharing of information in order to reach market-sharing agreements in which they divide the market up into segments and agree to produce only enough for their allocated segment. • The coordination of a reduction in purchases, forcing the suppliers to sell their inputs below market prices. • The restriction of market access if large industry players exclude smaller rivals, thus forcing them to pay higher prices for their inputs.

The three dimensions that characterize an e-procurement market based on its business functionality are that  (1) they are horizontal marketplaces  (2) in which long-term contractual purchasing agreements are used  (3) to buy indirect goods.  Other market characteristics of e-procurement are:- Net marketplaces are that they are independently owned, they are many-to-many markets, and they use fixed-price catalogs. E-procurement companies serve as intermediaries connecting hundreds of online suppliers offering millions of MRO goods to business firms who pay a fee to join the market, thus it is a public marketplace. They are mediated by an independent third party that purports to represent both buyers and sellers; however, they are likely to have a bias in favor of the buyer because they include the catalogs of competing suppliers and competing e-distributors.

Value chain management services benefit The value chain management services benefit buyers by automating a firm’s entire procurement process including purchase orders, requisitions, sourcing, business rules enforcement, invoicing, and payment. For the suppliers, they provide automation of the entire selling business process including catalog creation, content management, order management, fulfillment, invoicing, shipment, and settlement.
