These cables are cheap and the network interface cards are cheap as well compared to Fiber NIC cards. In that sense UTP cables are most preferred for patch panels and computer connections to the network. They are also the easiest to work with. Shielded-twisted pair is another type of copper cabling. This is used when you need to run cable through an area that has a lot of Electromagnetic Interference.
Professor Babcock NT1310 April 3, 2015 Unit 3 Assignment 1 Hierarchical Star Topology Hierarchical network topology is similar to the C: drive on your windows PC. This has a central root node which is at the top with a point to point link between each node on down. As you may have noticed this means it acts as a hierarchy with there being a main node and then it branches down from there. One of the best things about this type of topology is that fault identification is easy. This network can be expanded by the addition of secondary nodes.
It was designed to provide 3,000Hz bandwidth, perfectly adequate for a voice signal. Copper has a maximum distance of 90 meters if you exceed the 90m meter limit you will start getting attenuation problems which means you will start losing signal strengths. Fiber optic cable has many more advantages than copper cabling. It is much more secure and has complete immunity to electromagnetic interference. With this type of cabling there are
VOIP phones- voice over internet protocol is a technology that allows phone calls to be made through the internet. An advantage of this system is that there is no additional charge for phone calls beyond the charge for the internet through its service provider. VOIP uses a data network. Skype/Facetime- is a VOIP software application that allows for calls to be made over the
ATM uses fixed size packets (53 bytes) for data communication; frame relay uses variable packet sizes depending on the type of information to be sent. Both information blocks have a header in addition to data block and transfer is connection oriented. Frame Relay is used to connect Local Area Networks (LAN) and it is not implemented within a single area network contrast to ATM where data transfers are within a single LAN. ATM is designed to be convenient for hardware implementation and therefore, cost is higher compared to frame relay, which is software controlled. Therefore frame relay is less expensive and upgrading is easier.
So pretty much small networks can just be built using just the layer 2 devices and most corporate networks would have to have a mix of layer 2-7. The reason why small networks just use layer 2 is because products are cheap and its and easy way of providing connectivity to small workgroups. Multi-level switches are more expensive and complicated to setup and deploy. All of layer 7 switching is pretty much the SI to make forwarding decisions about HTTP traffic using your information in the URL.. So pretty much dealing with your cookies and websites you visited.
It contains many routers that work independently, without network connections to the other routers. c. It holds routers from multiple ISPs, allowing high-speed but inexpensive interconnects between ISPs. d. It connects to other ISP sites using some kind of WAN links. Answer: A, D. ISPs use the concept of a point of presence (POP) as the location where the ISP places its
The CAT5E will help prevent cross-talk and works for 10/100Mb and 1000Mb or Gigabit Ethernet. The cable will allow the computers to be connected to a hub. Unless there is a crossover cable, each computer will make a single lead to a port on the hub. There needs to be enough ports for each of the computers on the network. For an instance La Jolla has six computers so that mean that there will have to be at least six ports unless La Jolla were to get more computers.
Cable internet is a broadband connection with a Ethernet handoff to the customer that fits right into the existing network. Additionally, this layout would be very similar to what Northeastern Health Services, Inc. staff have seen at home and other locations. Third, Northeastern Health Services, Inc. would evaluate the complexity of the innovation. Again, cable internet is a simple hand off to the customer and should integrate seamlessly into the existing network design. Fourth, Northeastern Health Services, Inc. would evaluate the trialability of the innovation.
Another major advantage is that most of the computing is done on the remote server and because of this, the requirements of “onsite hardware” is greatly reduced. This kind of a setup allows the physician to access all information at any time from anyplace with Internet access. ("Binary spectrum,emr,"
