CS Theory What is CS Theory ? Up until now, we’ve talked a lot about some different tools for approaching problems, but there are still a lot of questions left unanswered - What types of problems can we solve with computing? - What’s the most efficient possible solution? - How can we integrate other disciplines into computing? - What are other ways we can perform computation? CS theory involves thinking a..

Computer Security Function Abstractions Data Abstractions Programming Paradigms Control Lists OOP HOFs Recursive data structure Function Recursion Growth Declarative Computer Security - Web security : Are you on the website that you think you are on and does it do what you think it does? - Network security : Who can see what you are doing online? - Systems security : Who has access to software & data on your lapt.. SQL : The Sequel Table A table stores data. It consists of a fixed number of columns, data entires stored in rows. - To make a table in SQL, use a CREATE TABLE statement - To create rows of data, UNION together SELECT statements - To create rows of data from existing table, use a SELECT statement with a FROM clause Join - Given multiple tables, we can join them together by specifying their names, separated by co.. Declarative Programming Programming Paradigms - Up until now, we’ve been focused (primarily) on imperative programming. - Imperative program contain explicit instructions to tell the computer how to accomplish something. The interpreter then executes those instructions - Now, we’ll learn about declarative programming, where we can just tell the computer what we want, instead of how we want it done. The interpreter then.. Streams Streams Lazy Evaluation in Scheme Lazy evaluation - In Python, iterators and generators allowed for lazy evaluation - Scheme doesn't have iterators. How about a list? Streams : Instead of iterators, Scheme uses streams - Stream : (linked) list whose rest is lazily evaluated : A promise to compute - cdr returns the rest of a list : For normal lists, the rest is another list : The rest of a stream.. μ΄μ 1 2 3 4 Β·Β·Β· 6 λ€μ
