Computer Basics (1) This is a pre-test to determine what students know about computer basics prior to learning about applications that will be used in the computer class. crolinger published on October 24, 20134 responses 1 « Previous Next » Questions in vertical order 1/20 What is digital? There are four levels of programming language: machine language, assembly language, high-level languages, and fourth-generation languages. Information broken into segments Series of 1's and 0's Allows the user to interact with the machine (i.e. to click on an icon, or delete a file) 2/20 What defines what will happen when a statement is executed? Compiler Interpreter Semantics Syntax 3/20 The source isn't the program's original code True False 4/20 A single binary digit, 0 or 1 Type answer. Hint: 3 characters 5/20 CPU stands for Central Processing Unit True False 6/20 Identifiers are various words used when writing programs True False 7/20 A series of instructions that the hardware executes one after another. Type answer. Hint: 7 characters 8/20 RAM stands for Readily Accessible Memory True False 9/20 Allows the user to interact with the machine (i.e. to click on an icon, or delete a file) Type answer. Hint: 14 characters 10/20 What is a gigabyte? 1024 megabytes 1024 bytes 1024 kilobytes 8 Bits 11/20 Main software of a computer Type answer. Hint: 16 characters 12/20 What are reserved words? Define what will happen when a statement is executed Series of 1's and 0's Used to separate the words and symbols used in a program, consists of blanks, tabs, and newline characters Identifiers that have a special meaning in a programming language that can only be used in predefined ways 13/20 An error that occurs during program execution, and causes the program to terminate abnormally or "crash" is called a Run-time Error Psuedocode Compile-time error Logical error 14/20 fetch-decode-execute Compiles code one line at a time an runs that line after it is compiled. Converts Java code into byte code that is run by the Java Virtual Machine A cycle, where an instruction is fetched from the main memory and put into instruction register. The program program counter increases to get ready for the next cycle. Then the instruction is decoded electronically to determine which operation to carry out. Finally, the control unit turns on the correct circuitry to carry out the instruction, which may load a data value into a register or add two values together, for example. An error that occurs during program execution, and causes the program to terminate abnormally or "crash" 15/20 Constant stream of unbroken information Type answer. Hint: 6 characters 16/20 How many levels of programming language are there? 2 3 4 5 17/20 What is a sampling rate? Number of digital measurements per second Constant stream of unbroke information A series of instructions that the hardware executes one after another. Number system with 10 digits (0 to 9) 18/20 What is a LAN? Local Architecture Network Local Apple Network Local Access Network Latam Airlines Group 19/20 What is hardware? Instructions that computers read and execute; programs Physical components of the computer Stores programs and data being used, usually volatile 8 Bits 20/20 A white space is a break in computer coding True False
