Brewer's paradox
Paxos theorem
CAP theorem
FLP impossibility
The CAP theorem, formulated by Eric Brewer, asserts that a distributed system can provide at most two out of the three properties: Consistency, Availability, and Partition tolerance. This trade-off guides the design choices for distributed databases and services. Understanding CAP helps in selecting the right architecture based on requirements. .
What distinguishes asymmetric encryption from symmetric encryption in terms of key usage?
Asymmetric does not use keys
Symmetric uses two keys
Asymmetric uses a public and private key pair whereas symmetric uses a single shared key
Asymmetric uses only one key
Asymmetric encryption employs a pair of mathematically related keys: a public key for encryption and a private key for decryption. Symmetric encryption uses the same shared secret key for both encryption and decryption. Asymmetric methods facilitate secure key exchange over untrusted channels. .

Cheat Sheet

  1. Moore's Law and Transistor Scaling -

    Moore's Law predicts that transistor count on integrated circuits doubles approximately every 24 months, a staple fact in technology trivia and chip history. Use the formula N=N₀×2^(t/24) to calculate growth over time and memorize "double or trouble" as a fun cue. This scaling principle explains how early 4004 CPUs evolved into today's multi-core processors.

  2. The Birth of the Internet and TCP/IP -

    Trivia on technology often centers on ARPANET's launch in 1969 and the 1983 adoption of TCP/IP, the protocols that power today's web. A handy tip is "69 to 83" to link ARPANET's start year and TCP/IP standardization. Understanding these milestones helps answer tech trivia questions about packet routing and global connectivity.

  3. Evolution of Mobile Networks (1G to 5G) -

    From analog voice in 1G to high-speed data in 5G, mobile generations are a common category in tech trivia questions. Recall "Voice, Text, Data, Smart, Hyper" to mark 1G through 5G progress and note 5G's top speeds of 1 - 20 Gbps. This overview arms you for questions on GSM, LTE, and beyond.

  4. Programming Paradigms: OOP vs. Functional -

    Questions about programming styles frequently contrast object-oriented programming (Java, C++) with functional programming (Haskell, Scala). Remember the rhyme "Classes and States, Functions and Fates" to differentiate OOP's mutable objects from functional purity. Knowing these paradigms is essential for tech trivia on software design.

  5. Encryption Essentials and Hashing -

    Whether it's technology trivia or security quizzes, distinguishing symmetric (AES) from asymmetric (RSA) encryption and recognizing SHA-2 hashing is vital. A mnemonic like "Symmetric Shares, Asymmetric Pairs, Hashes One-Way" helps lock in their roles. This knowledge empowers you to tackle questions on cybersecurity fundamentals.
