- This e-book is intensely, super outmoded. lots of the layout counsel date again to the time while IE five. five and six have been the innovative, and the examples are geared toward IE and Netscape Navigator clients! accordingly, the guidelines & options are almost lifeless now that IE 7 is typical, IE eight at the horizon, and FFox three approximately to be published.
- This e-book is stuffed with statements comparable to "PNG-8 and PNG-24 codecs have just recently got complete help from the main used-browsers, Netscape Navigator 6 and web Explorer 5"(pg 290). that is how outdated this book's information are.

Its 2008, do not buy whatever written ahead of 2006 with a view to study simple website design. you are going to prove wasting precious time, as I did.

It allows the SGSN to retrieve or update GPRS subscription and GPRS location information in the HLR during location-management or authentication procedures. The MAP protocol has been modified to take into account this interface.
The subnetwork formed by the SGSNs and the GGSNs is called the GPRS core network. In order to reuse the GSM nodes, new interfaces have been defined between the GSM network nodes and the different elements of the GPRS core network. 1. The protocol layer has been split into two planes. On one side there is the transmission plane, which is mainly used for the transfer of user data. The signaling plane is used for the control and support of the transmission plane functions. 2 deals with the transmission and signaling planes.
