GOTO is the structure that causes the logic to jump to a different place in the program. The IF statement allows the programmer to control a program entering a section of code or not based on whether a given condition is true or false. An important function of the IF statement is that it allows the program to select an action based upon the users input. Single-Dual Alternatives and Case Structures * What are the similarities and differences
(Choose two answers.) a. Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM.
In operating systems, memory management is used to block individual memory change user’s demand. In the application, memory management is ensures that there is adequate memory for object and data structure for each running program. There are five requirements that memory management have. The four requirements are relocation,
(Choose two answers.) a. Used for short-term memory e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of the following is true about the process of read data, as described in the chapter?
Why do global variables make a program difficult to debug? Any statement in a program can change the value of a global variable. To find where a bad value is coming from, a programmer would have to track down every statement that has access to that variable. Algorithm Workbench 1. Design a module named timesTen.
Cobol is a procedural language, and its programs are broken into four divisions: Identification, Environment, Data and Procedure. Pascal: 1970,
Chkdsk: This tool checks the integrity of the harddrives in your machine this tool can check and correct errors found on the local harddrive. The tool can be launched from a command prompt by opening the command prompt and typing in chkdsk. Chkdsk has many options such as chkdsk /f. This command will fix the errors found when you run just the standard chkdsk this only report the status of the harddrive. Next tool on our list is the disk defragmenter tool.
