@ computers to computer connected together via a crossover cable. No hub, switch, domain or central server.
Does coaxial cable used in the so-called last mile have anought capcity for future broadband needs?
Coaxial cable, depending on the type, can have a large frequency bandwidth capability. And with multi-frequency systems, coax should be around for quite awhile yet. I also think one of the other items keeping cable companies using coax is also the expense of fiber-optic cable and the cost in manpower to change it out. A lot of cable companies are in the process of doing so, but it's going to be slow going, simply because of the costs involved.
A mile in a 25 yard pool is considered a 1650, or 66 lengths.
Procedures to maintain contact with your networks?
what procedures do you use to initiate and to maintain contact with your networks
Where can you download driver for Fedora 10 for an Intel DG31PR motherboard?
The NIC on that motherboard, a Realtek RTL8111, is already supported in Fedora's kernel.
How could the company improve the availability and fault tolerance of its network?
Use subnetting to break up the broadcast domain, as well as improve manageability. Also subnets will improve bandwidth usage.
How does CDP gather the neighbor devices network address information?
CDP is a Cisco proprietary protocol; it only works between Cisco devices. If CDP is enabled on a Cisco network device, it will regularly send frames with information about itself out its interfaces.

Which of the following initiates an ARP request?
An ARP request may be initiated anytime a client needs to know the IP address of a machine from its MAC address.
255.255.252.0
yes
What is the maximum number of subnets in class A using this mask of 255.255.192.0?
Ok good question
To subnet any network requires borrowing host addresses
The 255.255.192.0 regardless of class says host addresses start at CIDR (Classless Inter Domain Routing Protocol) /18. So if we borrow every available host address space then we have 2^14 = 16,384 possible subnet addresses available, NOT.
In reality we have 11111111.11111111.11000000.00000000 or a /18 network.
Every network / subnet requires two special reserved addresses. The network or zero address, and the last address in the range which will be assigned as the broadcast address.
So we can't borrow all of the bits for sub netting. If we only leave one we will only have two addresses for the hosts, this won't work because we need to reserve two.
We have to leave two so we will have 2^2 = 4. We can then give each subnet a network address and a broadcast address and still have 2 usable hosts' addresses. If we do this we only have 2^12 subnets = 4096.
Each subnet will only have two usable host addresses and two reserved addresses. See the math confirms that 4096 * 4 = 16384 which is the total number of addresses in the address space we started with.
When connect switch to switch which cable to use?
All depends on the switch if the switch is intelligent and have auto detection which most switches have now a days you can use either one i.e straight through or crossover but if the switch is dumb you have to use crossover cable and plug it in the up-link port the process is called daisy chaining.
For the past 7 years i have yet to come across a switch that don't have auto-detection for cables and link but in some old setups i have still see old technology.
RIP is a protocol used by routers to exchange information about their routing tables. In dynamic routing, a router learns from other routers about possible routes by advertising what they know. RIP is a protocol that can do that.
What types of networks do the abbreviation LAN and WAN stand for?
Local Area Network and Wide Area Network.
Network definition for ingress router and egress router?
An ingress router is a Label Switch Router that is a starting point (source) for a given Label Switched Path (LSP). An ingress router may be an egress router or an intermediate router for any other LSP(s). Hence the role of ingress and egress routers is LSP specific.
An egress router is a Label Switch Router that is an end point (drain) for a given Label Switched Path (LSP). An egress router may be an ingress router or an intermediate router for any other LSP(s). Hence the role of egress and ingress routers is LSP specific.
Can you reset a D-link DP-300 or DP-301 print server with lost password or IP?
Yes. In most cases you can reset your D-link DP-300 series or DP-301 series print server yourself even if you don't know the password or IP. This comes in handy in situations such as when the server has made up its own password after being connected to a new router.
Cross your fingers and try the following steps...
1) Install the psadmin software if you have not already. If you have lost the psadmin software then search for it on the web.
2) Start the psadmin software and click "factory reset".
3) If the software demands a password, try "SYSxxxx", where xxxx stands for the last four digits of the MAC address located on the underside of your server. (Example: if your MAC address were "63 XE 29 44 F2 96", then your password would be SYSF296.)
4) Click yes to confirm the reset.
5) Follow the non-intuitive instructions provided with your server to set it up again. (Note that a Quick Install Guide will likely be more useful than a manual for this step. If you have lost your Quick Install Guide then try downloading it from D-link's website, http:/www.dlink.com/default.aspx Locate your model via "product quick find" or "find your product" then click on "support resources" and look for a quick installation guide.)
Good luck!
What is a non proprietary network protocol?
A non-proprietary protocol is one that is not closed and/or owned by any individual or corporation. TCP/IP is an example.
What technology enables you to designate a specific local address for various network services?
Port forwarding
solicited-node multicast address
