- 17. 17 Source Code Management • Git OS developers use Git to clone and track Tizen package source code – https://review.tizen.org/git/ • Gerrit Code is reviewed using Gerrit – https://review.tizen.org/gerrit • GBS (git-build-system) is used to locally build packages • MIC is an image creator. It's used to create images for Tizen*. • JIRA is used to track bugs and to gather feature requests – https://bugs.tizen.org https://source.tizen.org/documentation/developer- guide/environment-setup
- 18. 18 Tizen* OS Compliance • Tizen* OS Compliance is designed to ensure mobile device implementations and applications work together – Mobile device implementations: if implemented to a profile, a device will provide a consistent behavior defined by that profile to applications, and provide a consistent user experience – https://source.tizen.org/compliance/compliance- specification – Applications: if built to this specification, applications will run on compliant devices which implement the APIs it uses. Applications MAY be targeted to a specific profile if necessary – https://source.tizen.org/compliance/application-compliance
- 19. 19 Tizen* OS Compliance Platform & Profiles • The current profile is – Mobile: Handsets, tablets • Additional profiles are expected in the future, possibly including – IVI: In-vehicle infotainment systems – TV: DTV/STB/IPTV systems – Clamshell: Notebook style laptops – Camera: Cameras – Printer: Printers
- 21. 21 Examples of Innovation and Differentiation • Security • Camera stack • Connectivity • Power Management
- 22. 22 Tizen* Security Tizen* takes a layered approach to security, with an innovative framework that allows platforms to implement a manageable security solution, and minimizing the attack vectors of malware. WRT - Web Runtime • Each application is sandboxed • Each Application is digitally signed by the developer and by the distributor (Tizen store) • Encrypted application is decoded at runtime, not at install SMACK - Simplified Mandatory Access Control in the Kernel • Each application has its own SMACK label • Any access to an object in the system (e.g. contacts database) is checked against the SMACK rules Content Security Framework • Provides privileges necessary to properly protect the device • APIs to scan applications, device content, URLs used by the applications, etc.

- 45. 45 Risk Factors The above statements and any others in this document that refer to plans and expectations for the third quarter, the year and the future are forward-looking statements that involve a number of risks and uncertainties. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “will,” “should” and their variations identify forward-looking statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel’s actual results, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could cause actual results to differ materially from the company’s expectations. Demand could be different from Intel's expectations due to factors including changes in business and economic conditions; customer acceptance of Intel’s and competitors’ products; supply constraints and other disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Uncertainty in global economic and financial conditions poses a risk that consumers and businesses may defer purchases in response to negative financial events, which could negatively affect product demand and other related matters. Intel operates in intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings and introductions, marketing programs and pricing pressures and Intel’s response to such actions; and Intel’s ability to respond quickly to technological developments and to incorporate new features into its products. The gross margin percentage could vary significantly from expectations based on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; start-up costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; product manufacturing quality/yields; and impairments of long-lived assets, including manufacturing, assembly/test and intangible assets. Intel's results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. Intel’s results could be affected by the timing of closing of acquisitions and divestitures. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel’s ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’s SEC filings, including the company’s most recent reports on Form 10-Q, Form 10-K and earnings release.
