WebJun 24, 2024 · In the context of websites and apps, caching is defined as storing content in a temporary storage, like that on the user's browser or device or on an intermediate server, to reduce the time it takes to access that file. According to HTTP Archive, among the top 300,000 sites, the user's browser can cache nearly half of all the downloaded content. WebThe ﬁle group structure in the optimal cache placement solution for the CCS enables us to obtain a new information- theoretic lower bound on the average rate for any caching scheme under nonuniform ﬁle popularity. It is derived by applying the optimal ﬁle group structure obtained for the CCS to the genie-aided construction method [18], [19].
