What is the first action performed when a cisco router starts up?
I believe that would be the POST (power-on self-test, where the router does some internal checks before continuing).

It assigns a value that represents an infinite metric to the poisoned route.
It sends back the poisoned route update to the same interface from where it was received.
Structure of an ipv4 address the types of ipv4 address available?
Structure of IP address
IP address is used by routers, bridges and all kinds of end systems to focus data packets/frames on a particular destination/source port. Following defines the structure of a typical IP address.
IPv4 address is 32 bit long. This 32 bit stream grouped into four segments. Each group may contain 1 byte (or 8 bits)
11000000 11100100 00010001 00111001
Each group of 8 bits can be converted to a decimal number. Following is the decimal conversion of above IP address.
192.228.17.57
This is the general look of an IP address. It will contain four decimal numbers separated by a dot. Each decimal can run up to 255. That is 255.255.255.255 .
IP address gives many information about the network. For example;
Example IP Address:192.248.8.0/28
This network ID is: 192.248.8.0.
Hosts in this network: 32bit - 28 bit = 16 hosts
Last IP (also known as Broadcast IP) = 192.248.8.15
The "/28" is not an integral part of IP address. We use this information is used to derive information from IP address.
Types of IP Addresses
IP Addresses are grouped into five classes. Class A - Class E.
Class A: 1st bit of a class A IP address always has '0'. Next seven bits for network and rest 24 bits for host.
CLass B: 1st two bits of a class B IP address always has '10'. Next 14 bits for Network and rest 16 bits for host.
Class C: 1st Three bits of a Class C IP address has '110'. Next 21 bits for network and rest 8 bits for host.
Class D: 1st Four bits of Class D IP Address has '1110' and rest of the bits are multicast.
Class E: 1st Five bits has '11110' and rest of the bits are allocated for future usages.
Hope this will help you!

What is true of the configuration of switch S1?
Switch ports Fa0/1 and Fa0/3 are configured to carry data from multiple VLANs.
Which application layer protocols correctly match a corresponding function?
HTTP transfers data from a web server to a client
Telnet provides a virtual connection for remote access
ip address is basically the address of your internet connection, like a=each and every house is registered with the government and the address is known,
likewise, your internet connection is registered with your ISP(internet service provider).
ip address can be either static or dynamic, like the words suggest,
static ip address will remain the same whereas dynamic ips will change from time to time(each time you connect).
there are ways to change your ip address, which require software, but its only needed by hackers or crackers..... you wont be needing it.....

Can i install Linksys wireless-b router without the disk?
Yes. 1.Plug router into power 2. find and connect to a wi-fi network called "linksys" 3. once connection is established, open web browser 4.type 192.168.1.1 in the address bar then hit enter. 5.user name and password box should show up 6.type "admin" in the password box, hit enter (leave user name blank) 7.from there you can configure the router. once you are done changing the options , plug the internet into the back. You are DONE!
How do you copy IOS software in cisco switches if tftp server not available?
You can use scp (depending on the IOS version), or you can use Xmodem over the console line.
It's usually easier to setup a tftp server on a random PC or laptop, though.
How do you add com2 to the connection ports?
If your system only has one COM: port, you will have to physically add in a card or USB-RS232 serial adapter, and follow the installation instructions.
If your system has 2 COM: ports, make sure that in the CMOS (BIOS) settings, that the port isn't disabled or assigned as an InfraRed port.
Also, make sure that you physically have the connectors at the back of the unit available. Many motherboards offer COM2: only as an option, and it requires an optional (not included) cable that hooks to the motherboard.
How are computers used in schools?
One obvious use for computers is to conduct math drills. But computers are increasing used as a reference tool, using the internet to provide information on virtually any topic.
Whats the difference between baseband and broadband?
In Baseband, data is sent as digital signals through the media as a single channel that uses the entire bandwidth of the media. Baseband communication is bi-directional, which means that the same channel can be used to send and receive signals. In Baseband no frequency-division multiplexing is not possible. (Multiplexing (short muxing) is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.)
Broadband sends information in the form of an analog signal. Each transmission is assigned to a portion of the bandwidth, hence multiple transmissions are possible at the same time. Broadband communication is unidirectional, so in order to send and receive, two pathways are needed. This can be accomplished either by assigning a frequency for sending and assigning a frequency for receiving along the same cable or by using two cables, one for sending and one for receiving. In broadband frequency-division multiplexing is possible

Where do you locate slide out switch for 2002 palomino stampede?
I own this model and year. The switch is located on the wall to your left if you are facing the couch that slides out. Is it about 2 feet from the floor. It should be marked in and out to indicate if you want to slide it in either direction.
