In large organizations, having one SMS site for the management of all your network resources is not really the ideal solution. Here, implementing a site hierarchy that has multiple SMS sites is the better solution. A SMS site consists of the following SMS components: SMS site server SMS site systems SMS clients and resources The SMS hierarchy is the structure that links multiple sites together. The SMS hierarchy is created by linking sites together so that parent-child relationships can be formed: Parent site: This is a SMS site that contains Read More

Data Over Cable Service Interface Specification (DOCSIS) defines the interface standards for cable modems and supporting equipment involved in high speed data transfer and distribution over cable television system networks. It permits additional high-speed data transfer over an existing cable TV system and is widely used by television operators to offer Internet access through an already existing hybrid fiber coaxial infrastructure. Other devices that recognize and support DOCSIS include HDTV's and Web-enabled set-top boxes for televisions. In other words, the same cable that brings you CSI can also allow you Read More

DDR SDRAM is Double Data Rate SDRAM. DDR SDRAM is an improvement over regular SDRAM, also known as SDR SDRAM (Single Data Rate SDRAM). DDR SDRAM doubles the bandwidth of SDR DRAM by transferring data twice per cycle on both edges of the clock signal, implementing burst mode data transfer. DDR SDRAM is being supplanted by DDR2 SDRAM. Standard DDR SDRAM DIMM's DDR SDRAM is normally packaged in DIMM modules. DIMM Module Chip Type Clock Speed Data Rate Transfer Rate PC1600 DDR200 100 200 1,600 PC2100 DDR266 133 266 2,133 Read More

Routers are basically used to connect different networks by allowing them to exchange routing information with each other. A router is a network layer device that maintains a database called an IP routing table by learning the ip addresses of directly connected networks by default. After enabling the IP Routing process, the learned networks can also be seen in the IP routing table by exchanging the IP routing information. Cisco is the worldwide leader in providing routers, switches, and other networking devices. Cisco routers are known as the best solution Read More

If you are a Real Player audio user who wants to download a file or play some audio or audio-video file and all code programs are not present, you may receive an error message “Audio Data: Tag 8192”. Naive computer users and people who are not really technically savvy would usually find the error message odd and if you are not really into it and try fixing the problem by changing the settings in your divx, musicplayer or real player program. If you do this, chances are you might end Read More

QPSK (Quadrature Phase Shift Keying) is a phase modulation algorithm. Phase modulation is a frequency modulation version where the carrier wave’s phase is modulated to encode bits of digital information in each phase change. The “PSK” in QPSK refers to the use of Phased Shift Keying. Phased Shift Keying is a form of phase modulation that is accomplished by using a discrete number of states. QPSK refers to PSK with 4 states. With half that number of states, there is a BPSK (Binary Phased Shift Keying). With twice the number Read More
