In which this can lead to downtime for the business and its users. Most companies rely on their network and cannot afford to have any downtime at all; therefore, it is necessary to have the correct topology to help make your business profitable. A bank or a major business depends on having a reliable network that will not have a significant amount of downtime that would affect their everyday business. For the second scenario XYZ Technology Consultants, I also think that Ethernet would be the better choice here. With the amount of floors, being occupied the reliability of using CAT 5, wireless, or Fiber Optic lines to ensure fast and reliable data transfer would seem to be necessary.
This network would be primarily a client-based model because there is no server involved in the networking of these computers. This network can be managed through the switches that would be installed to ensure it is running smoothly. Case Project 3-2 EBiz.com has 250 networked computers and five servers and uses a star topology wired
The benefit of an NAS system comes in its simplicity. The user buys the system and attaches said system to their existing network or to their local computer via an Ethernet port. There is no need for a monitor, mouse or even a keyboard. The unit is completely self contained. To communicate with the network, the NAS system uses TCP/IP protocol and is often managed via a web browser interface.
Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero. The first octet is used to define the network ID. Class A address cannot be greater than 127 because a value of 128 would require the left-most bit be set to 1. Class B addresses always have the first two high-order bits that are set to 10 and are used for medium-sized networks that have a moderate number of hosts connected to them. The Class B network ID, will utilize the first two octets for the network ID, which allows more network IDs and fewer hosts than a Class A network, because it uses an additional octet for the network.
Some of these machines may be just under 2TB or up to 40TB. With port replication and add-on hardware drive controller cards there really isn’t a limit on storage capacity. Is there any fault tolerance (such as RAID) built into a NAS device? RAID 50 is fairly stable if set-up correctly but RAID 10 has been declared as one of the best setups because even if more drives fail at one time there will be no data loss. Are management features available?
The __________________ tool provides a central access point for all of the network controls and connections on a computer running Windows 7. Network and Sharing Center 3. A device that connects one network to another is called a __________________. router 4. The most common method for illustrating the operations of a networking stack is the __________________, which consists of __________________ layers.
C. two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable. 7. A. hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth. C. hubs allow collisions to occur when two attached devices send data at the same time. 8.
9. Which of the following are advantages of using a bridge to interconnect LANs? Answer: Relatively inexpensive, Easy to install, Reduces collision domains Section 5-3 10. The network switch operates at what layer of the OSI model? Answer: layer 2 -Data Link Layer 11.
This will provide more security and better efficiency. Peer to Peer networks are just not secure enough. It would only take one dishonest employee or one employee having a bad day to try to sabotage a coworker’s computer. Although peer to peer networks are a good starting point for small businesses, the security risk makes them a hazard. Each user is responsible for controlling their own data, resources, and login information.
It is set up with a network security key when is enabled, the key encrypts the data that is sends from one computer to another computer across the network; unfortunately this is a very vulnerable systems and is very easy to crack (Microsoft, 2015). The WEP was one of the earlier efforts when it came to protecting a network. It has three settings off or no security, 64-bit is a weak security and 128-bit he best of the three options it has better security. It is not a very difficult system to break into and the use of it reduces the performance a little bit. Running this network at its default setting meant that anyone would be able to log into the network.
