What is the best explanation for digital data is represented in computers in binary? A. The binary number system is the only number system flexible enough to allow for representing data other than numbers. B. As a consequence of history: early pioneers of computing were making secret codes in binary, and this simply evolved into modern computing. C. It's impossible to build a computer machine that uses anything but binary to represent numbers. D. It's easier, cheaper, and more reliab...

Overflow : error that results when the number of bits is not enough to hold the number, like a car's odometer "rolling over" Round-off : error that results when the number of bits is not enough to represent the actual number, like 3 digits to represent π as 3.14 Lossy : Compressing data in a way that throws some data away and makes it almost impossible to recover the original, great compression, like JPEG images Lossless 2 : Compressing data in a way that preserves all data awa...

Algorithm : A precise sequence of instructions for processes that can be implemented in a programming language and executed by a computer. Control Structure : one or more programming language statements that control the flow of a computer program. Examples: If/Else structure or a loop structure. Computer : a machine that processes information under the control of a program. Program : sequence of instructions that control the computer. To run, it must be loaded into the computer's m...

How are procedures abstractions in computer science? A. They are Blocks of code that do something specific B. They represent the lowest level of code for the computer to run C. They use actual values to represent concepts D. They can be used without understanding or seeing the code used : D - abstractions in code are code that is simplified What do parameters used in a procedure provide? A. A way to get values into the procedure making code more flexible B. A way to return values calcu...

Algorithm At its core, an algorithm is really just a generalized, conceptual solution to a problem that can later be implemented in some real-world form like a computer program. Application Program Interface Application program interface (API) is a set of routines, protocols, and tools for constructing software applications. An API specifies how software components should interact. In addition, APIs are used when programming graphical user interface (GUI) components. Binary A numeric syste...

What is a special data type that has one of two values? a boolean What are the two values a boolean can have? true or false What are the three ways a boolean can be returned? as a result of evaluating a condition as a result of comparing two values when evaluating one or more Boolean conditions 10 MOD 2 0 20 MOD 0 error 20 MOD 4 0 4 MOD 20 4 0 MOD 4 0 How can you determine if a number is even or odd? by using x MOD 2, if the answer is 1, it is odd, if the answer is 0, it is even What...

Computing is closely tied to ____, computing innovation have far reaching ____. creativity; innovation The two impacts of computing is? Facilitate creation of computational artifacts and help people solve personal, societal, and global problems. What do computing tools enhance? The creative process What does collaboration facilitate? Multiple perspectives, diverse talents and skil,s What is abstraction? Information and detail reduction to focus on the relevant concepts of something. Abst...
