Unit 4 Homework PT 1420 Brian Clear 6 April 2014 Unit 4 Assignment 1: Homework Short Answer 1. How do modules help you to reuse code in a program? Modules allow the programmer to write an operation once and then be executed any time it is needed. 2. Name and describe the two parts that a module definition has in most languages.
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
Memory Management Requirements Your Name POS 355 Date Due Instructor Name Memory Management Memory Management is used to optimize a systems performance through the use of control, coordination, and assignment of blocks of memory used for multiple processes. It is handled through hardware, operating system (OS), programs, and applications. The main goal is to maximize performance. (Rouse, 2012) Memory Management has five basic requirements; 1. Relocation is executing processes separately from physical memory and is handled through paging, partitioning, or segmentation.
1. Disable unnecessary services Not every system service that is running on a stock Windows 7 machine is necessary. A number of services can either be disabled or modified to run only when needed. Once you make these changes, the service no longer has to consume system resources and the system no longer has to spend time starting the service. 2.
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,
NT1430 Unit 2 Assignment 1 Chapter 5 The Linux Utilities 1. Which command can you use to determine who is logged in on a specific terminal? * The command you can use is the $ w as well as who, and finger command. 3. What Happens when you give the following commands if the file named done already exists?
Why are these numbers useful when you run processes in the background? Which utility displays the PID numbers of the commands you are running? A PID is a Process Identification Number. Each of these numbers identifies the command running in the background. Then the shell displays another prompt and you can enter another command.
To create a new user and assign a password, you would execute an SQL command similar to the following: To assign a password for an existing user, you would instead execute a command similar to this: To show the system and status variables, enter the “SHOW VARIABLES” command, which when executed will give results specific to your environment that will resemble this: Configuring InnoDB: Configuring InnoDB will require different parameters for different environments all of which will have slightly unique needs. For my system, I will set up a sample of how my my.cnf file would be configured for my needs. The my.cnf (or in some cases my.ini) file is generally located in one of the three following file paths: C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf
Check the workstations using ipconfig /all and find out if the ip range is within the address range you assigned, if it is a different address then the workstation failed to contact the DHCP server and has gone into apipa mode. The Network Interface Card might be assigned an incorrect driver. Another possible cause of the problem is that the patch cable is not plugged into the Network Interface Card, or is not connected to a switch on the other end. However, it could be that the server has run out of IP addresses that it can assign to clients. You can easily tell if this is the problem by comparing the size of the DHCP address scope to the number of devices on your network that request IP addresses from the DHCP server.
Part 2 Design, implement, test, and debug a program that reads the file you created by the list in Part 1 and displays the records in a JFrame. You may either display all entries in the list at once or display them one at a time; the user interface is up to you. Protect against not being able to open the file. Flowchart
