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, 2013 Stacked 1/20 What is a gigabyte? 1024 megabytes 1024 bytes 1024 kilobytes 8 Bits 2/20 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 3/20 CPU stands for Central Processing Unit True False 4/20 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 5/20 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 n...
