CCT Test Exam Questions and Answers 100% Pass

CCT Test Exam Questions and Answers 100% Pass Algorithm - a sequence of steps; formulates problems as a series of logical steps. Analog vs. Digital - ANALOG signal fluctuates exactly like the original stimulus; DIGITAL signal is based on binary code and it is purposefully discontinuous Analog computing - non-programmable and task specific; computing is the manipulation of numbers and symbols following established procedures. it is not just what a machine does/digital/electric. EX: analog computers - astrolabes or slide rule Application layer - the interface/application; specifies the shared protocols and interface methods used by hosts in a communications network; **top layer in the internet stack, only part of the internet process humans see Architecture - a specific way of organizing the flow and representation of information; represented visually by an x-ray diagram Base (transistor) - switches electricity between two states Binary - numbers or states coded as present (1) or absent (0); anything that can be represented in binary can be computed Bit Depth - more bits mean more information -> the more bits you have the greater the bit depth Bit - one bit can represent two unique things, smallest piece of data 2100% Pass Guarantee Emily Charlene All Rights Reserved © 2025 Byte - 8 bits is a byte -> this is the basic unite of measure for information in computing Black box - a thing (architecture) that does something (algorithm); every blackbox is a sociotechnical system Boolean (or Conditional) Expression - an expression used in programming languages that produces a Boolean value when evaluated. A Boolean value is either true or false. Branching (programming) - common type of control flow - a branch is if the the else if statements in a control flow Boolean Logic - basic data structure: true or false, 1 or 0; human reasoning reduced to a sequence of binary propositions (T/F) that can be strung together infinitely; George Boole invented Boolean Logic Gates - constructed by connecting transistors together Capture (Digital Capture) - The conversion of human behavior and real-world data into machine input. -> Digital capture samples the original source. Circuit Board - A printed circuit board mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate Code (programming) - collection of computer instructions using computer-readable programming language; source code is transformed into binary machine code Collector (transistor) - collects electricity 3100% Pass Guarantee Emily Charlene All Rights Reserved © 2025 Computing - the manipulation of numbers and symbols followed established procedures 'Contextual' information - "context is increasingly computable"; we are always interfacing. increasing amounts of contextual (passive) information are available to the machine) -- capture. *context is computable EX: searching paris (get Hilton or city), micro historical activity, location, profiles and preference, social network "Context is increasingly computable" - We are always interfacing - increasingly amounts of contextual (passive) information are available to the machine: the location, micro histories of activity, profiles and preferences, social networks Control flow (for loop, while loop, if statement) - determines the order of execution, embodies the logic of the algorithm Converting between binary and decimal - always read right to left; 10110 = 1, 2, 4, 8, 16 (add together the places marked by 1) so 2 + 4 + 16 = 22 [each binary slot is represented numerically by a base of 2 to an increasing power, starting at 0] CPU - Central Processing Unit - also called a central processor or
