Which of the following actions can you NOT perform from the Windows Firewall control panel? (choose all that apply) (C) Create firewall exceptions based on port numbers 6. Which of the following policy modifications would make it harder for intrudes to penetrate user passwords by a brute force attack? (choose all that apply) (A) Increase the value of the Reset Account Login Counter after Policy 7. Connection security rules requires that network traffic allowed through the
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.
3) When the printer displays “abcd” or garbled text, you may want to delete the current printer status and reinstall the printer to the correct driver. This should clear the problem, just remember to reboot the system and start all over again. It is a possibility that when you originally load the printer, it may have gotten corrupted. Basic Networking: Course NT1210/NT1310 1. OSI Model: Open System Interconnection * Is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers 7) Application Layer | 6) Presentation Layer | 5) Session Layer | 4) Transport Layer | 3) Network Layer | 2) Data Link Layer | 1) Physical Layer | * The model group’s communication functions into seven logical layers.
hard drive, CDROM, or Removable) * Under Exit Tab, You are given the option on how to exit from BIOS with or without saving changes Explain POST: Power On Self Test * POST is a test to determine a computer’s hardware is not faulty before it boots * When a problem occurs BIOS will register an error * A sound messaging speaking is located on the motherboard that will issue a series of beeps when a problem is found. The beep sequence is like Morse code for your computer. * To determine what each beep stands for go to computerhope.com/beep.htm for a list of their definitions * If BIOS is corrupted POST will not be achieved and will most likely show a message of corrupted CMOS , Complementary Metal Oxide Semiconductor, or not output will be show at all In summary, this video showed me that the BIOS is a useful tool to have access to in determining the running conditions of your
Understanding the BIOS and POST * Why is it necessary to use ROM for the BIOS and not RAM? It is necessary to use ROM for the BIOS because the data in the RAM is cleared when the computer shuts down, but the data in the ROM is always there for the BIOS to use * How do the POST beep codes make troubleshooting a computer start-up problem easier? The computer POST, tests the computer to make sure it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST, the computer gives a single beep (with some computer BIOS manufacturers it may beep twice) as it starts up and will continue to start normally. However, if the computer fails the POST, the computer will either not beep at all or will generate a beep code, which tells the user the source of the problem.
Having beep codes to help decipher the problem makes the repairs easier. The hard disk is busy when performing a cold boot because it is testing all of the hardware. With a cold boot, the BIOS verifies RAM by performing a read/write test of each memory address. It checks for a keyboard, mouse and for a (PCI) bus and, if it finds one, checks all the PCI cards. If the BIOS finds any errors during the POST, it will notify you by a series of beeps or a text message displayed on the screen.
However, before you began the updating process you need to look at the hardware compatibility of you machines with the Windows 7 program. Due to the fact that you want to move from the Windows XP operating system to the Windows 7 operating system and not having ever installed the Windows Vista operating system means that you might be at risk for more compatibility problems between the program and the machines. With going this was you would need to preform a Clean Installation would have to be performed; meaning that aside from any settings that are able to be moved via one of the migration tools, it would be necessary to perform a backup of all of your machines in order to keep from permanently losing any important files or documents. Ultimately I would recommend to you to run the Windows 7 Upgrade Advisory on any system that you want to upgrade. In doing this it will tell you if there are any compatibility issues on each machine.
Third, u must have a blank DVD. Then, you start your macbook, and u find the bootcamp program in launchpad. Next, u choose the “download drive program” and “start to install window system”buttons. After that, u will receive a tip that u have to part the whole hard disk to 2 parts. And then, hit the “install” button.
By going with the star topology to corporate servers to hold all of the stores data and licenses for each software that hey own a simple tape drive will allow the Bead Bar to backup all main stream data and anything else located on the corporate servers. By using the Windows servers they can set up active directory to scan for old/unlicensed software and actually make scripts and send them down to all of the stores to uninstall software and install the update one or a new piece of software depending on if they switch software. The fastest way to monitor what needs to change with any set up is to ask the end user what they like and don’t like and see what can be changed from there. Even considering the fact that end users don’t like new systems to begin with due mainly to the fact that change is bad if you don’t use the system personally all you have are an error logs which help you fix problems that have been resolved already and make fixes to a possibly broken
