Educating yourself about Ethernet QoS quality of service providers will ensure you have a better understanding of the underlying technology that has been developed for computer networks. With the technical details of computer networks being so intimidating, especially for novices, this may seem a daunting subject. You may discover that the underlying concepts are much less complex than you had once thought.Computer networks are established when more than one system is linked, enhancing the resources and potential usefulness of all the computers involved in the network. Networks may be small in size, encompassing only a few systems within the same room. Larger networks are possible as well, spanning the entire globe.The technology used to establish such a network is what makes it all possible. Traditional networks have been limited to the infrastructure that was originally built to transmit audio data for telephones. This technology allowed for the growth of networks and the Internet to come into being.While older networking technologies have their limitations, keeping current networks that are dependent on them to operate from enjoying the benefits of newer technologies, there have been many advances in putting the telephone network and infrastructure to use for digital networking systems. In some areas and regions, networking options may be limited by available technologies are limited funds. When the demands placed on such networks is light, it may be possible to get plenty of useful life out of conventional networking technology.Learning more about computer networks and the technology behind them can be very rewarding. If you are interested in understanding more about this subject, you would do well to locate the resources and information needed to do so. There are many available resources for learning more about the technology used in computer networking, as well as what your choice in a provider will mean in terms of services.With a firm understanding of the options and services you have available to choose from, you can get the most for your investment. Choosing a provider who will be able to meet your needs as well as your costs can give you access to the services you need in terms of your networking needs. A little further understanding on your options can be invaluable when you are attempting to navigate among them.A simple web search can give you the information needed to further outline your options, as well as to expand upon your understanding of the underlying technology.
There are two competitors in the cellphone industry network worldwide, GSM and CDMA. CDMA (Code Division Multiple Access) works in US through Verizon Wireless. GSM (Global System for Mobile Communication) is a bit older than its rival and it has developed GPRS (Global Packet Radio Service) technology. GPRS has increasingly gained more popularity due to its affiliation to GSM. The majority of network service providers in US use this technology. In fact, approximately 80% from he global cellphone market connect through GSM network as it is the most common standard.As a result of GSM’ popularity, a whole industry trade organization has been created, the GSM Association, including the worldwide mobile phone carriers and manufacturers. The GSM Association estimates that over 4.3 billion people from over 212 countries are GSM users. This technology developed the 2G mobile phone system (2nd generation), making possible the storage into the system more data communication applications. GSM also developed a new way of fast communication worldwide via the short message service system (SMS). The GPRS technology soon developed into EDGE (Enhanced Data Rates for GSM Evolution), a faster way for data transmission. The biggest advantages of the GSM technology are represented by network’s maturity, GSM being more stable, its users benefit from less signal deterioration inside buildings, this type of network is used in all parts of the world making roaming much more accessible.The main difference between the GSM and CDMA technology is the fact that GMS does not allocate the entire frequency to the end-user, being divided in time-slots for a better utilization of the bandwidth. CDMA technology uses the digital modulation called spread spectrum and the entire frequency is available to the user, creating a unique code for each users, allocating bandwidth. This works by spreading the voice data over the channel. When reaching the end-user, the information is added together just like from a puzzle and decoded.Most BlackBerry phones are empowered with CDMA technology, making data transmission faster, although many of them work with EDGE. The issue is that these two technologies are not quite compatible, as they are very strong competitors. So, if your phone works with CDMA, and you travel outside USA, you may encounter network problems. If your BlackBerry works with GSM, it should be OK, as most countries besides USA adopted the GSM technology. In such cases, the best thing you should do is talk to your network provider.
