On top of that, depending on the size of the file will determine how many can fit on the flash drive. The first step in using a flash drive is to Read More

MPLS stands for Multi Protocol Label Switching. The MPLS is often referred to as the layer in between the Data Link and Network layers because of where it operates. The MPLS serves as a method to forward packets of data easily by using labels. What are the Data Link and Network layers? In the seven-layer OSI model, a model used to explain how a computer operates and communicates within itself. The Data Link and Network Layers are parts of this model, and correspond to the second and third layers respectively. Read More

Excessive heat damages electronics. Monitoring CPU and other computer components’ temperature help them run properly. To make the most of monitoring software, users must ensure that ACPI functionality is enabled in their motherboard BIOS. Why CPU Temperature is so Important When the first affordable PCs were offered to the general public in the early 80’s, system engineers and designers took into consideration the heat that system components emitted and ensured that their case and cooling designs handled the appropriate amount of heat so system damage or instability was rarely an Read More

When does the 502 Proxy Error Occur? A 502 proxy error may occur if the ISA Server site and content rule are configured to Read More

Most people usually look to Signal to Noise Ratio to measure the signal quality of either audio or video communications. Signal to noise ratio is usually written either S/N or SNR. Most of the time the signal to noise ratio is measured in decibels. A decibel is a measure of power or loudness. Not to get too technical, Signal to Noise Ratio is a great way to easily determine which audio or video component produces a clearer signal or can transfer a clearer signal to a speaker, TV set or Read More

Some ITSPs (Internet Telephony Service Providers) offer a service called an SIP trunk, which allows PBX services to use VoIP (Voice-over-IP) services outside of the enterprise network via the same connection as that used for the Internet. As a result, SIP trunking services can save an organization a significant amount of money as it eliminates the need for additional VoIP hardware or software for the organization’s network. The minimum equipment required to use SIP trunking is a PBX, ITSP, and an edge device for coordinating the routing of SIP traffic. Read More
