Why would the ping command accept the name yahoo.com instead of an actual IP address?
This is possible because of what is called Domain Name Resolution (DNS). Your computer sends a lookup request for 'yahoo.com' to a DNS server, which resolves the domain name into it's IP address.
Does the MAC address still display when we disconnect the cable to your network adaptors?
If the cable is disconnected, the address will not display.
What is a router on stick inter vlan routing?
A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.
Which of the following statements about public switched networks are true?
Transmissions are slower than in point-to-point connections
Your data is transmitted along the same pathways as other companies' traffic
They're commonly used by companies as an Internet connection link
What is numerical aparture in optic fiber?
Numerical aparture is the light collecting capability of the optical fiber.
How can you work with radmin server?
Radmin Server installes on the remote computer which you want to access from your own one. These are simple steps to set remote connection and to work with radmin server:1. Download Radmin Server 3.5. Execute rserv35.msi and follow the on-screen instructions.
2. Download Radmin Viewer 3.5. Execute rview35.msi and follow the on-screen instructions.
3. Configure Radmin Server on the remote PCRight Click on the Radmin Server tray icon and choose "Settings For Radmin Server". Select the "Permissions" button to set the password for network access to the Radmin Server. You must know the IP address of your remote computer. To know it move your mouse pointer over the Radmin Server tray icon. It will show you the IP address. Now your Radmin Server is ready for starting the remote access connection.
4. Run Radmin Viewer on the local computerFrom the Start menu click on "Radmin Viewer", create a new connection and enter the IP address of the remote computer. Then select your connection type and press "Connect". Enter the password you already set on the remote PC and enjoy working remotely.

What is meant by connection state information in a virtual circuit network?
In a virtual circuit network, information exchange occurs in a dedicated path between the source and the destination. Each active path is given some Virtual Circuit number on the fly. The routers in this path need to keep information about this path and to which interface the data, coming from a particular interface, has to be redirected. This information is termed as connection state information.
Whenever a new connection is established, this 'connection state information' has to be updated in router's table, and whenever the connection completes exchanging data this 'connection state information' has to be discarded.
In short, connection state information is the information required/maintained by a router to redirect data, to proper interface, in an active connection.
What does www stand for at the being of the web address?
The "WWW" at the beginning of an address stands for World Wide Web.

It's a network only without cables. The Access point(sometimes built into the router) is the hub of the network. Most wireless devices DO NOT transmit to each other but to the hub that routes the traffic to the other devices. This is usually done on a certain frequency (fixed) determined by the routers configuration.
In electrical installation why do you need to ensure the cables are not twisted or plaited?
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
Identify the connector that can be used to connect RG6 cables?
The "F" connector is the most common type that is used on RG6 cable. This is the universal connector for home use of RG6 with antennas, CATV, satellite, and consumer electronics.
What are the four basic steps of troubleshooting a modem?
Step 1 - Analyze the circuit
First, see if the circuit operates correctly. If the circuit operates correctly, there is no need to troubleshoot and this would be the last step. If the circuit does NOT operate correctly, then you must go to the next step.
Step 2 - Check the setup
If the circuit is not operating correctly, check to see if you have overlooked something simple. Check connections and buttons to see if they are set correctly. If you checked the setup and the setup is good, but the the circuit does not operate correctly, go on to step 3.
Step 3 - Calculate and measure values
First, calculate to determine the values that should be present in the circuit that is not working properly by using I = V/R. Make voltage, current or resistance measurements. In most cases, the voltage measurements are made first. Voltage measurements provide useful information about the circuit and are made without breaking the circuit. If more information is needed, make current or resistance measurements. Remember, the circuit MUST be broken to make these measurements. Make as many measurements as needed. As the pieces of the puzzle begin to fall into place, identifying the fault becomes easier.
Step 4 - Check the results
Compare the calculated to measured values. You should have enough information to identify the fault. Replace the faulted component and perform step 1 again. If the circuit operates properly, the circuit is fixed.

Each host on a network has a unique ip address with how many bytes?
A bit is a 1 or a 0 to the computer. A byte is 8 bits. A byte can represent any number from 0-256.
for example: 00000001 = 1 / 00000010 = 2 / 00000100 = 4 / 00000111 = 7 (4+2+1).
This probably wont make you understand it but anyway an IP address like 192.168.1.101 consists of 4 bytes, or 32 bits (8 * 4). Same thing with 154.12.154.254 or 1.1.1.1
What is the maximum number of hosts for a Class A Network?
The maximum number of hosts per class B network is 65536.
