Describe how 10BaseT Networks achieve fault tolerance.?
104745
10BaseT networks meaning, well I belive you would actually have to list more of a detailed question to get a proper answer, but on the network topology, you could use a Star network where all the clients are connected to one server, so that if a client dies, all the others can still use the data. It would seriously depend on the network toplogy to answer your question, so hopefully that did it for you. If not use the link below

If you have a system with a single point of failure then if that failure happens the system stops working. If you have multiple points of failure then the system will continue to work as long as failures haven't happened at multiple points.\n\nAn example of SPOF system would be an online database hosted on a single server in a single building publishing through a single router.\n\nAn example of a MPOF system would be an online database hosted on several servers each with a separate router and at least one in a geographically different locale.\n\nMPOF systems are more expensive as you have redundant equipment but if the system is business critical then it's worth the time money and effort to give an uninterrupted service.

This is a networking problem - look up 'Linear Bus', 'Star' or 'Hub', 'Token Ring' and 'Fully Connected Mesh'.\n\nYou need 21 for a fully connected topology, but you could do it with far less.

assuming you are talking about networking, (including the internet) each computer on a network is called a node. each node has a Network Interface card (NIC) Each NIC has its own Media Access Control (mac) address provided by the manufacturer.\n\nThe very first line of protection comes from the NIC when it transmits special frames of data (about 1500 bytes of info) the frames contain MAC addresses of both senders and recievers,the data, and about 4 bytes called a Cyclic Redundancy check (CRC). The mac address makes sure it gets to the right node and the CRC makes sure the data is correct. The CRC is the answer to a complex binary arithmetic problem, using the rest of the data in the frame. if the sending and recieving node use the same formula and get the same CRC #'s the recieveing end knows the data is good. \non the internet theres somthing call internet protocal (IP) IP is carried with the data and has its own error checking.\ncheck out http://en.wikipedia.org/wiki/Tcp/ip

It was designed to be short-range, for many reasons:\n1) To avoid having too many networks too close to each other;\n2) To limit the amount of power use - more range, more power;\n3) There are already many long-range networks

That is a question which requires a hugh amount of time to answer.  You'd do better to just start searching the web for information on networking.  Also, "network" is something of an ambiguous term. Are you referring implementations of OSI?

Click on Start, Control Panel, then Network Connections. Right click on your Internet connection & select Properties. Then select Configure button. \n\nMaximum speed (bps). Users of 33.6K Modems should set this to 56700, while 56K Modem users should select 115200. \n\nEnable hardware flow control. Tick this setting to enable the use of hardware handshaking with your connection. For best connection stability & throughput ensure this setting is Ticked. Though in some (rare) cases you may find Unticking this setting can improve connection stability (Uses Software flow control instead). \n\n \nEnable modem error control. Tick this setting to enable the use of Modem error control, which will attempt to ensure data integrity in the connection, resending any damaged packets as necessary. I’d highly recommend enabling this. There are also Init strings available which can be used to disabled inefficient error control components.\n\nEnable modem compression. Data compression provides faster uploads/downloads depending on the data which is getting compressed. Should you have a Winmodem then you can leave this setting Unticked as these Modems do not support hardware compression. For regular, hardware, modems Tick this setting to enable the Modem to perform any data compression, which provides lower CPU usage over using software compression. As a result I’d recommend Ticking this setting for best system performance. \n\nShow terminal window. Tick this setting to have a Pre-dial terminal session appear. If you need to use this you’ll know. I can’t think of any modern ISP that would require you to use something archaic like this, though some more advanced users might use this to test the Modem. For everyone else just leave this Unticked. \n\n \n\nEnable modem speaker. Tick this setting to enable the speaker on the Modem to emit sound. This is fairly useful as you should be able to tell whether or not you can successfully connect or not just by listening to the connection when being dialled up. Untick this setting to mute the Modem’s speaker. \n\nClick Ok & select the Networking tab. \n\n \n\nType of dial-up server I am calling. Set this to PPP: Windows 95/98/NT4/2000, Internet unless your ISP has informed you otherwise, which is unlikely. \n\nNow select the Settings button. \n\n \n\nEnable LCP extensions. LCP (Link Control Protocol) extensions provide a way of establishing, configuring, maintaining, & terminating a PPP connection. You should leave this setting Ticked unless you experiencing problems connecting to your ISP as a result of its enabling. \n\nEnable software compression. Tick this setting to enable software (CPU) data compression for your connection. This will provide faster uploads/downloads depending on the data which is getting compressed. Should you have a Modem which can performance compression in hardware then I’d recommend you leave this setting Unticked & allow the Modem to perform any data compression – this should improve system performance slightly as the CPU will not be required to perform a task which can be done on separate, dedicated, hardware. Those would Winmodems should Tick this for optimal upload/download speeds, albeit it at the cost of some CPU cycles. \n\nNegotiate multi-link for single link connections. You can leave this setting Tick unless you experience problems connecting to your ISP (Error code 733 according to Microsoft), in which case Untick this. \n\nClick Ok after you’ve made your changes. \n\nFor the most efficient Internet connection you should Uninstall as many unnecessary Clients/Services/Protocols as possible, e.g. Client for Microsoft Networks & QoS Packet Scheduler. As you may have noticed from my Dial-up connection only Internet Protocol (TCP/IP) is installed.

A number of mechanisms help provide the reliability TCP guarantees. Each of these is described briefly below. \n\nChecksums. All TCP segments carry a checksum, which is used by the receiver to detect errors with either the TCP header or data. \n\nDuplicate data detection. It is possible for packets to be duplicated in packet switched network; therefore TCP keeps track of bytes received in order to discard duplicate copies of data that has already been received.2 \n\nRetransmissions. In order to guarantee delivery of data, TCP must implement retransmission schemes for data that may be lost or damaged. The use of positive acknowledgements by the receiver to the sender confirms successful reception of data. The lack of positive acknowledgements, coupled with a timeout period (see timers below) calls for a retransmission. \n\nSequencing. In packet switched networks, it is possible for packets to be delivered out of order. It is TCP's job to properly sequence segments it receives so it can deliver the byte stream data to an application in order. \n\nTimers. TCP maintains various static and dynamic timers on data sent. The sending TCP waits for the receiver to reply with an acknowledgement within a bounded length of time. If the timer expires before receiving an acknowledgement, the sender can retransmit the segment.

Unix or Linux would be my answer.  Linux especially can be adapted for a network's server needs.

Minimum would be one.\n\nA Class C, 255.255.255.0 would give you one network with 254 clients.\n\nSubnetting it 1 step further would be 255.255.255.128 which would give you 2 networks of 126 clients.\n\nFigure it out like this... taking the last octet (the .128) in binary... 1|000 0000\n\nLeft of the line represents the networks, to the right are the clients (-1) The line represents the division between the number of networks and the number of hosts.\n\nSo, every subnet further (move line right) would increase the number of networks, but reduce the number of clients.\n\nThe smallest number of subnets, you'd move the line all the way left (off the end).  This would give you 1 subnet of 254 clients. (255 - 1)

I could come up with this!\n\nFairness Algorithm: Packet Rings also have an inherent advantage for implementing fairness algorithms facilitating. \n\nRing bandwidth is a shared resource and is vulnerable to exploitation by individual users or nodes in the network version of the “the tragedy of the commons. \nA fairness mechanism that gives every customer on the ring a “fair” share of the ring. \nA ring-level fairness algorithm can and should allocate ring bandwidth as one global resource. \nFacilitate bandwidth policies that can allow maximum ring bandwidth to be utilized between any two nodes when there is no congestion can be implemented without the inflexibility of a fixed circuit-based system. like SONET but with greater effectiveness than point-to-point Ethernet.\n\nAlso.........\nThere are a few algorithms used in GSM. A3 is used to authenticate the user. A8 is used to generate a session encryption key. A5 is used to encrypt the session (there are 3 variants, A5/0 A5/1 and A5/2). Additionally the SIM card contains a user key called Ki.\n\nA3 and A8 exist on the SIM card. They are selected by the provider (COMP128-2 is the reference algorithm provided by the GSM Association however in the next generation this will change to an open algorithm after repeated cracks). The provider will have SIM cards made with Ki, A3 and A8 put into the SIM, and they will have the identical information in their databases. This information is never sent across the network under any circumstances.\nA3 and A8 are just place holder names, and do not define any specific algorithm. Rumor has it that Vodafone never used COMP128, so in 1999 when that was cracked, they were not vunerable. \nA5 however exists in the handset, and in order for the phone to work everywhere, the algorithm has to be the same. If it were not, you would get encryption in one place but not in others. One interesting note is that the user has no idea if encryption is enabled or not. This is a bad design flaw. The user may hear from sales literature that there is encryption and that the phone call is 'secure' when infact it is not.\nThe A3 algorithm is a one way hash. It takes a 128 bit number (provided by the cellular provider) and the Ki and generates a 32 bit response SRES. A8 will generate Kc, a 64 bit key that is used as the key for A5. Most implementations generate a new key for each session (a session is any time the phone and the GSM provider need to exchange data when they previously were not, such as a new call being placed). One problem with COMP128 is that 10 bits are all zeros!!! This is an intentional weakening of the algorithm (to help law enforcement who can get a warrant and does not need to crack the crypto???) by a factor of over 1000. The 64 bit encryption becomes 54 bits. I am unsure if COMP128-2 has this problem or not, as that is not published and is available only under string licensing from the GSM MoU in Dublin, Ireland!

How much bandwidth is setup for them? I have 4 pc's and a laptop on my home network running at 13 mps and have no problems

As many connections you have.  A router would allocate the connection request anyway.  How many do you want to add, 100?  I would add no more than 5.
