Where is the ip address on a cisco switch for telnet?
The Cisco switches I have seen don't have an IP address by default. You have to connect to the switch with a console cable - one that connects to the console port on the switch, and to the serial port on the computer - and do some initial configuration, including the IP address.

How is Data Encryption Standard work in details?
Data Encryption Standard is a symmetric-key algorithm for the encryption of electronic data. It is considered a block cipher because it uses an algorithm that takes a plaintext bits and transforms it through into another ciphertext bitstring of the same length

Difference between Internet and wan?
The difference between internet and wan is WANs are provided by companies licensed by the government to provide communications to the general public. The largest WAN in use today is the internet, which connects many smaller networks and millions of users from around the world.
If your computer only supports WEP encryption, but the wireless network uses WPA, you will not be able to connect to the network. However, most wireless networks can be configured to use WEP security or no security, which will allow you to connect. The trade-off is that the network becomes less secure. WEP encryption is possible to defeat, and turning off security will allow anyone connected to the network to view all data traffic, including private information. A better option may be to purchase a wireless adapter that supports WPA encryption. WPA was developed to fix the flaws of WEP, and is much stronger.
What is the difference be a frame and jframe?
- Frame is part of java.awt package and exists since JDK1.0. JFrame is part of javax.swing package and exists since JDK1.1.3 or something.
- Frame extends Window.
JFrame extends Frame.
- You can directly add components to Frame. You add components to JFrame.getContentPane().
- JFrame implements javax.swing.RootPaneContainer and javax.accessibility.Accessible interface. Frame does not. By virtue of that JFrame gets all the benefits that you get from JRootPane using a delegation model. e.g. you can set the border on ((JComponent) JFrame.getRootPane()).setBorder(...)
- JFrame directly supports javax.swing.JMenuBar.
- JFrame supports setting of close operation.
How are best practice implemented?
The world has evolved immensely over the past few years. One of the most significant changes is the excessive use of software. There is a program or an automated system for each and every single detail in our routines, but businesses and organizations have been getting the lion's share when it comes to software.
There are different systems that ensure that companies are in compliance with different rules and regulations. Other programs can help in managing risks by calculating them and computing different algorithms to reduce them. And, who can forget about the bundles of software that helps accountants and companies' financial advisors determine the profitability of the company?

Can you connect a wired router to a wireless access point and if so how?
Each Wireless Access Point generally has 4 connections (ethernet wired socket), using which a wired router can be connected to any one of them and then configure the wired router ....
6 How can a computer use ARP to break security?
But if the gateway computer's knowledge of the destination computer's MAC address is either missing or too old and expired, it must send a broadcast to all of the computers on the LAN network asking which specific computer is assigned to the IP address of the packet the gateway is trying to forward. To do this the gateway broadcasts an ARP Request that will be received by every computer on the Ethernet LAN. The request simply asks for a reply from the one machine that is currently assigned to the IP contained in the request. Each computer on the LAN checks to see whether the IP is (one of) its own. The computer finding a match with (one of) its own IPs will send an ARP Reply back to the requesting device. When the gateway computer receives the ARP Reply, it has the MAC address of the replying computer along with the replying computer's IP address, contained in the reply packet. The receiving machine enters this information into a "cache" of all similar IP-address-to-MAC-address pairings which is maintained for every machine it has communicated with on the LAN. This is known as the machine's "ARP Cache" since it retains the history of all previous unexpired ARP Replies which it has received. Every computer participating on the LAN maintains its own similar ARP cache containing the IP-to-MAC relationships that allow them to properly address IP packets with Ethernet MAC addresses.
Notice that in this example, our gateway computer added this new entry into its ARP cache upon the receipt of an ARP Reply packet. The ARP protocol is so simple - just asking who has the IP and replying "I have the IP" - that there is no provision for any sort of security or authentication of the replying computer. In other words, any computer on the LAN could claim to have the IP in question. The implementation of the ARP protocol is so simple and straightforward that the receipt of an ARP reply at any time, even when there are no ARP requests outstanding, causes the receiving computer to add the newly received information to its ARP cache. Consequently, if the gateway computer were to receive a SPOOFED ARP REPLY from an attacking computer claiming that it was assigned an IP that belonged to some other computer, the gateway would trustingly and blindly REPLACE its current correct entry with the maliciously misleading replacement! If at the same time the malicious attacking computer were to send a similar ARP reply to the computer being hijacked, maliciously replacing the ARP cache entry for the gateway computer, then any subsequent traffic bound for the gateway would instead be sent to the attacking computer. If the attacker forwards any of the redirected traffic it receives onto the proper original computer - after inspecting and perhaps even modifying the data - neither of the intercepted computers will detect that all of their communications is now being relayed through an unknown and probably malicious intermediary computer. By merely injecting two ARP reply packets into a totally trusting LAN, any malicious computer is able to receive all traffic going back and forth between any two computers on the LAN such as any target machine and the LAN's gateway.
What are the uses of windows NT?
As normal Windows.
2000, XP, Vista, and 7 are all technically Windows NT
Since this was posted under Cable Modems, I'm assuming that you are asking about
the (Data Over Cable Service Interface Specification (DOCSIS) cable modem which allows
different cable companies and different cable modem manufactures all to adhere to a uniform
set of protocols and modulation schemes to allow for inter and intra market competition.
Go to Wikipedia and search DOCSIS for more information if that truly was your question.
Discuss the need or lack of need for a network layer OSI layer 3 in a broadcast network?
The network layer is responsible for addressing nodes in a logical way. It is also responsible for making decisions on routing a packet from one network to another.
In a broadcast network, routing is not needed. A transmission from any attached station is received by all other attached stations.
Other functions,such as sequencing, flow control, error control, can be done at layer 2. The MAC sublayer is responsible for addressing across the LAN. With the Data link layer and its sublayers (MAC & LLC), no network layer is needed.
If there's a WAN port on your hub, use that (If your x-port hub actually has x+1 ports, chances are the extra port is actually a WAN port). Otherwise, you probably can't connect that hub to another hub using a standard patch cable and will need a crossover cable. Some hubs will allow you to switch a port between normal and WAN mode, however (I believe some Trendnet hubs have this feature?), so you might want to check first. This is usually a hardware feature - normal hubs usually are not advanced enough to contain software interfaces for a browser to interact with)
Anyone can own a webserver. A webserver is simply a computer with software installed capable of serving a website etc (like IIS or Apache)
Open your web browser and navigate to http://www.ieee.org and in the upper right hand corner type "irrigation zigbee" in the search box. It is the first response.
The address for this paper is: http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?tp=&arnumber=4908331&isnumber=4908191
Unfortunately to view the whole thing you need to pay for it. I doubt you will be able to find it offered for free (legally at least).
How do you find the router password key to hook a new computer into an existing router?
Check security setting for wireless network in your router settings. Some routers allow to see the key, some mask it with asterisks. If your router masks the key (in router settings), you have to put a new key, if you want to connect more computers.
What is the difference between simple router and isr router?
ISR router will do lot of services compared with normal router. For example terminating VPN Sections, VoIP support, and bridging LAN/WAN cards. Basically ISR routers are modular routers, you can insert WAN T1/E1, SONET, etc cards. - kumar
What protocol allows hosts to exchange messages to indicate problems with packet delivery?
