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, 20135 responses 1 Questions in vertical order How many levels of programming language are there? 2 3 4 5 Constant stream of unbroken information Type answer (6 letters) Main software of a computer Type answer (16 letters) Identifiers are various words used when writing programs True False Allows the user to interact with the machine (i.e. to click on an icon, or delete a file) Type answer (14 letters) 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 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) A series of instructions that the hardware executes one after another. Type answer (7 letters) A white space is a break in computer coding True False What is a gigabyte? 1024 megabytes 1024 bytes 1024 kilobytes 8 Bits A single binary digit, 0 or 1 Type answer (3 letters) What defines what will happen when a statement is executed? Compiler Interpreter Semantics Syntax What is a LAN? Local Architecture Network Local Apple Network Local Access Network Latam Airlines Group 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 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) 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 RAM stands for Readily Accessible Memory True False The source isn't the program's original code True False CPU stands for Central Processing Unit True False 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"
