How to Run Dell Diagnostics

Dell computers include a diagnostic software tool that tests your computer's hardware for errors. You can choose to run this application when you boot up the computer. This software is useful when you have errors on your computer and are unable to figure out what the problem is. The Dell Diagnostics tool helps you troubleshoot and pinpoint problems with your system.

Step 1

Press the "Reset" button to reboot your Dell computer. Press the "F12" key when you see the Dell splash screen on your monitor. The computer's boot menu will open.

Step 2

Select "Boot to Utility Partition" using the arrow keys. Press "Enter" to boot to the customized Dell diagnostic partition.

Step 3

Press the "Tab" key to move the selection to "Test System." Press "Enter." Dell Diagnostics will start to run.

Step 4

Choose the "Express Test" option. This quick test ensures that your Dell hardware is functioning normally. You can also run the "Extended Test," which runs extra checkpoints on the system and takes up to an hour to complete, a "Custom Test," which lets you test only certain specified devices, or the "Symptom Tree," which lets you input hardware symptoms and checks the hardware based on the symptoms.

3. - Send a message to multiple people without revealing other recipients' identities    To send a message to someone without other recipients of the message knowing, use the Bcc line in the message. Bcc stands for blind carbon copy. If you add someone's name to the Bcc line, a copy of the message is sent to that person, but his or her name is not visible to other recipients.

 

Share large files the easy way.
 

Sharing a small file with a friend or client is easy. Just send it over email. Most email can handle up to 10 megabytes.

What if the file is over 10MB? Well, then it gets complicated. You have to set up a Web host and FTP accounts. It's a huge hassle.

Today's Cool Site makes file sharing a snap. You just register for a free account and then start uploading. The free account gives you 10 gigabytes of storage space. However, file sizes are limited to 200MB.

The service lets you upload multiple files at a time.

Calibrate your monitor for better photos

With QuickGamma, you can adjust the monitor's gamma uniformly. Meaning you affect the amount of red, green and blue simultaneously. Or you can adjust the gamma of the three colors independently. This lets you really go in-depth with your color adjustments.

After you install QuickGamma, make a test print of your photo. Make sure your print settings are set to best.

You'll want to use the same paper you plan on using for your photos. If possible, use matte photo paper. Glossy paper adds a lot of sheen and can make colors look brighter than they are.

Now let the print dry for a few minutes. This will help maintain color accuracy. That's because wet ink usually looks brighter than dry ink. Again the point is to have an accurate photo to aid in calibration.

Once it's dry, set it in a place with good ambient light. Natural light is best, as it won't add yellow hues that artificial lights tend to. Now you can start adjusting your monitor with QuickGamma.

How to Secure a Wireless Network from Hackers?

In order to secure a wireless network from hackers, we should take proper steps to save ourselves against security issues. If you don't secure a wireless network from hackers, you might end up without its service. The consequence might also include the utilization of our network to attack further networks. To secure a wireless network from hackers, you should follow these simple wireless networking tips:

1.       Strategic antenna placement:

The first thing you have to do is to position the access point's antenna in a place which restricts the range of its signal to go further than the required area. You should not put the antenna close to a window because glass can't obstruct its signals. Place it in a central location of the building.

Use WEP:

WEP stands for Wireless encryption protocol.  It's a customary technique for encrypting traffic on a wireless network. You should never skip it as that will allow hackers to get instant access to the traffic over a wireless network.

3.       Change the SSID, disable the broadcast of SSID:

SSID stands for service set identifier.  It is the recognition thread utilized by the wireless access point due to which the customers are capable of starting connections. For every wireless access point arranged, select an exclusive as well as unique SSID. Also, if it's attainable, hold back the broadcast of the SSID out over the antenna. It won appear in the listing of offered networks, while being able to provide services as usual.

4.       Disable DHCP:

By doing this, the hackers will have to decode the TCP/IP parameters, subnet mask as well as the IP address in order to hack your wireless network.

5.       Disable or modify SNMP settings:

Change the private as well as public community settings of SNMP. You can also just disable it. Otherwise the hackers will be able to utilize SNMP to get significant info regarding your wireless network.

6.       Utilize access lists:

For additional security of your wireless network, and if your access point support this feature, employ an access list. An access list lets us determine precisely which machinery is permitted to attach to an access point. The access points which include the access list can employ trivial file transfer protocol (TFTP) now and then in order to download modernized lists to steer clear of hackers.
