    Study Notes

    Cloud Computing

    • The father of cloud computing is J.C.R. Licklider.
    • Cloud providers offer intermediation and auditing services.
    • Resource abstraction and interoperability are important aspects of cloud computing.

    Data Communication

    • A pair of quad and an octet are equivalent to 2 pairs, 1 quad, and 1 octet.
    • The K-map for the function F(w, x, y, z) = ∑(0, 1, 2, 4, 5, 6, 8, 9, 12, 13, 14) can be used to simplify the function.

    Digital Logic

    • DeMorgan's theorem states that (xy)' = x' + y' and (x + y)' = x'y'.
    • The NAND gate is used to implement logical operations.
    • Flip-flops and registers are used to store binary data.

    Boolean Algebra

    • The distributive property of Boolean algebra is X + XY = X and X(X + Y) = XY.
    • The absorption law is X + XY = X.
    • The law of contradiction is X(X + Y) = X.

    C Programming

    • A C function can return only one value.
    • A pointer variable can be assigned the address of another variable.
    • The unary & operator yields the address of a variable.

    Cryptography

    • Modular exponentiation is used in RSA encryption.
    • The addition operation in Elliptic Curve Cryptography is the counterpart of modular multiplication in RSA.

    Computer Architecture

    • The addressing modes are direct, indirect, immediate, indexed, and register.
    • The PC-relative addressing mode uses the program counter instead of a general-purpose register.
    • The process of checking the status flags is called polling.

    Operating System

    • Raid classification is used to categorize different RAID configurations.
    • Form-based login service, HTTP Basic authentication, and logout service are security services registered and configured by Spring Security.

    Database Management

    • Cardinality refers to the number of tuples in a relation.
    • Degree refers to the number of attributes in a relation.

    Machine Learning

    • The Bayes rule can be used to solve probabilistic queries.
    • The output of the training process in machine learning is a model.

    Compiler Design

    • The difference between the minimum number of states required to recognize L1 and L2 is 3.

    Theory of Computation

    • L1 = {w | w does not contain the string "tr"} and L2 = {w | w contains the string "tr"} are languages.
    • The language {a^m b^n c^(m+n) | m, n ≥ 1} is not regular but context-free.

    Miscellaneous

    • Iterative, prototype, spiral, and waterfall models are software development life cycle models.
    • The cache memory is used to increase the speed of the system by reducing memory access time.
