Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended November 29, 2019 on file with the SEC (our “Annual Report”).
Reclassifications	Reclassification Certain immaterial prior year amounts have been reclassified to conform to current year presentation in the condensed consolidated statements of cash flows and notes to condensed consolidated financial statements.
Recently Adopted Accounting Guidance	Recently Adopted Accounting Guidance On February 24, 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), (“ASC 842”), a new standard related to leases to increase transparency and comparability among organizations by requiring the recognition of right-of-use (“ROU”) assets and lease liabilities on the balance sheet for all leases with terms greater than twelve months, including for those leases classified as operating leases under the legacy standard (“ASC 840”). Under ASC 842, added disclosures are required as compared to ASC 840 to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. On November 30, 2019, the beginning of our fiscal year 2020, we adopted ASC 842 using the alternative modified retrospective transition method provided in ASU 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, we recorded ROU assets and lease liabilities of approximately $519 million and $618 million, respectively, at the adoption date and did not include any retrospective adjustments to comparative periods to reflect the adoption of ASC 842. The lease liabilities reflect the remaining minimum rental payments for our existing leases as of the adoption date, discounted using our incremental borrowing rate for each lease. The standard had no impact on our consolidated net income or cash flows. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carry forward our assessments on whether a contract was or contains a lease, our historical lease classification and our initial direct costs for any leases that existed prior to adoption date. We also elected the practical expedient that allowed us to carry forward our accounting treatment for existing land easements. We did not elect the hindsight practical expedient to determine the lease term for existing leases. On August 28, 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging, requiring expanded hedge accounting for both non-financial and financial risk components and refining the measurement of hedge results to better reflect an entity’s hedging strategies. The updated standard also amends the presentation and disclosure requirements and changes how entities assess hedge effectiveness. On November 30, 2019, the beginning of our fiscal year 2020, we adopted the accounting requirements of the updated standard utilizing the modified retrospective method of transition. The adoption of this standard did not have a material impact on our condensed consolidated financial statements and related disclosures.
Leases [Policy Text Block]	Leases We determine if an arrangement is or contains a lease at contract inception. In certain of our lease arrangements, primarily those related to our data center arrangements, judgment is required in determining if a contract contains a lease. For these arrangements, there is judgment in evaluating if the arrangement involves an identified asset that is physically distinct or whether we have the right to substantially all of the capacity of an identified asset that is not physically distinct. In arrangements that involved an identified asset, there is also judgment in evaluating if we have the right to direct the use of that asset. We do not have any finance leases. Operating leases are recorded in our condensed consolidated balance sheets. ROU assets and lease liabilities are measured at the lease commencement date based on the present value of the remaining lease payments over the lease term, determined using the discount rate for the lease at the commencement date. Because the rate implicit in our leases is not readily determinable, we use our incremental borrowing rate as the discount rate, which approximates the interest rate at which we could borrow on a collateralized basis with similar terms and payments and in similar economic environments. Our leases have remaining lease terms of up to 12 years, some of which include options to extend the lease for up to 9 years and options to terminate the lease within 1 year. Optional periods to extend the lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised. We also have one land lease that expires in 2091. Operating lease expense is recognized on a straight-line basis over the lease term. We account for lease and non-lease components, principally common area maintenance for our facilities leases, as a single lease component for our facilities and data center leases.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Not Yet Effective On June 16, 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses, requiring the measurement and recognition of expected credit losses for financial assets held at amortized cost, which include our accounts receivable and contract assets. The standard also requires that we recognize credit impairment losses related to our available-for-sale debt securities through an allowance for credit losses instead of a reduction in the cost basis. The effective date of the new standard for public companies is for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition with a cumulative effect adjustment recorded to opening retained earnings as of the initial adoption date. The updated standard is effective for us beginning in the first quarter of fiscal 2021 and we do not plan to early adopt. We are currently evaluating the effect that the standard will have on our condensed consolidated financial statements and related disclosures. With the exception of the new standard discussed above, there have been no other recent accounting pronouncements or changes in accounting pronouncements during the three months ended February 28, 2020, as compared to the recent accounting pronouncements described in our Annual Report, that are of significance or potential significance to us.
