Local Area Network

Executing the command switch port port-security mac-address 00C0.35F0.8301 on a port (F01) in interface configuration mode enables port security and sets a specific MAC address as the allowed device for that port. This means only the device with the MAC address 00C0.35F0.8301 will be permitted to send traffic through the port. If another device attempts to connect, the switch will either drop the traffic or shut down the port, depending on the configured violation action. This enhances network security by preventing unauthorized access.

It strictly depends on the model. Most routers have to be restarted in order to enable port forwarding.

that gives you 16 subnets with 14 usable IPs for hosts that is because one is for subnet and one for broadcas in that subnet

for example: 192.168.1.0/28 - subnet number

192.168.1.15 -broadcast number

usable IPs for hosts - IPs between them that is 14

Generally, no, unless the router is part of a server based system. A router is a dedicated device to routing packets between networks or subnets. It has no traditional server function such as print or file serving, etc.

Limited or no connectivity means there is not enough connection to the Internet server. This could be because there are problems with the modem or you are not close enough to get proper service.

There are no purely functional differences between a token ring token bus implementation and FDDI. In fact, the token bus is defined in IEEE 802.4, and FDDI's topology derives from that very standard. Think of FDDI as being a subset of 802.4. Refer to RFC 1042 (http://www.faqs.org/rfcs/rfc1042.html) for more details.

The remainder of my entry doesn't really apply to this question and is more subjective, but I do try to outline some other non-functional differences between the two standards.

Apart from functional differences, the obvious ones can be broken into a couple different parts off the top of my head: physical and application. The physical difference is that Token Ring pretty much uses coax cable as its medium while FDDI conspicuously uses fiber. From an application standpoint, Token Ring is short distance (coax has a maximum attenuation distance of 500 meters) while FDDI can traverse far greater distances while attaining greater throughput. As a result, FDDI would be much more scalable, supportive of many more users, and primarily used in large geographically-demanding environments but pricey; on the other hand, token ring would be for less scalable environments but cheaper.

Another non-functional difference would be noise immunizations. FDDI is inherently immune to most interferences that coax implementations would be heir to. Fluorescent lighting, various frequencies, and other causes of noise to fiber would not affect it in the same adverse manner that would apply to coax.

The default value for network diameter on a STP configuration is 7 (seven).

This value can be changed, using the command:

Switch(config)#spanning-tree vlan 1 root primary diameter 5

This command changes the network diameter 50 5 (five) hops from end to end

255.255.255.255 is for broadcasting

a third party firewall is any firewall that did not come with the computers operating system

the corresponding bit in the ip address is a host bit

If the packet's "Do Not Fragment" flag is set, then the packet is discarded and the sender is notified. Otherwise, the packet is fragmented into several pieces and will continue on to its final destination.

Well prejudice means judging someone before you even get to know him/her and discrimination means saying names about that person, teasing him/her weather he is black or white or just different.

UDP does not require as much resources as TCP but in the same time, it does not insure delivery of packets.

Digital Forensics

advanteg wireless net work

it means a street address or your home address

Is the Ethernet the oldest form of Local area connections?

Securities is where many wireless networks lost out.

Sometimes, wireless networks are unreliable - signals from wireless networking can suffer from interference beyond the control.

Wireless networks can be slower compared to wired networks

Compatibility - since it's a new technology component which are not made by the same company may not work together.

Weak signal strength due to some obstacles like heavy walls etc.

Additional range must be added using Repeaters and more access point. This leads to increase of cost.

MPLS is pretty complex, and the configuration will depend entirely on the device to which it's connected. Presumably, that's your ISP's router on the other end. They should tell you what configuration you need to use.

DNS - it handles both IpV4 and IPv6 addressing.
