| What is the network term for a device that sends and receives messages directly across the network? | Host |
| What type of network has computers that function as both servers and clients at the same time? | Peer to peer |
| What type topology uses icons to show where the devices are in the NW? | physical |
| What type of topology groups devices by how they use the network? | Logical |
| Is an IP addressing scheme included in a logical topology? | Yes |
| What is another word for communication rules? | protocols |
| What is the process of converting thoughts into the language, symbols, or sounds, for transmission? | Encoding |
| What does the sending host convert messages to before it is sent over the network? | Bits - a series of 1's & 0's |
| Which hosts decodes signals to interpret a message? | Destination host |
| What happens to frames that are too long or too short? | They are not delivered |
| What type of message is sent to all hosts at the same time? | Broadcast |
| What does the 100 mean when referencing the 100BASE-T Ethernet standard? | Speed of transmission |
| What is the address that is burned into the NIC card called? | Media Access Control (MAC) Address |
| Which type of address is used in an Ethernet frame header? | MAC Address |
| In an Ethernet frame, what detects transmission errors? | Frame check sequence |
| What type of message is sent to all hosts in a NW? | Broadcast |
| What layer interconnects the smaller, local networks? | Distribution Layer |
| What addressing scheme identifies the local host? | Logical addressing - IP |
| What is another name for IP address? | Network address |
| What two things does an IP address identify? | Network address & Host address |
| What part of the IP address do all devices within a single Access Layer share? | Network portion |
| Which two networking devices are used to connect hosts to the access layer? | Hub & Switch |
| What is usually the Distribution Layer device? | Router |
| What is the main goal of the Core Layer? | to transport data quickly |
| A hub receives a message on one port. Who does it send it to? | Every port attached to it |
| What device accepts messages only addressed to the correct MAC address? | NIC |
| What happens if two hosts try to send a message at the same time through a hub? | collision |
| What is the area of the NW called where a host receives a garbled message? | Collision domain |
| Can a switch forward a message to a specific host? | Yes |
| What address does a switch check for in its MAC table? | Destination (MAC) address |
| When using a switch, what allows many conversations to occur at the same time without causing collisions? | Point-to-point connections & Separate circuits |
| What happens when the switch receives a frame addressed to a new host that is not yet in the MAC address table? | It floods it out all it’s ports |
| How often is a MAC table updated? | Dynamically – whenever a new MAC address is read by the switch |
| A switch does not forward collisions. Therefore, every port on a switch is considered this. What is it? | A separate collision domain |
| Who receives broadcasts? | All hosts on the LAN |
| What is the broadcast MAC address in hexadecimal notation? | FFFF.FFFF.FFFF |
| What’s another name for a Local network? | Broadcast domain |
| What protocol does a sending host use to find a MAC address on a LAN if it knows the IP address? | ARP |
| What does a host do when using ARP, receives a MAC address? | Puts it in it’s ARP table |
| What do Distribution Layer devices connect? | Networks |
| What is inside a router packet? | IP addresses of Source and Destination & message data |
| What part of the IP address do routers read? | the network portion |
| Which table does a router use to make decisions on where a data packet is to be sent? | routing tables |
| What is the process of forwarding the packets towards their destination called? | Routing |
| Do routers forward broadcasts? | No |
| What is the address of the router interface connected to the same local network as the source host called? | default gateway |
| What device routes packets between networks? | router |
| If the default gateway is configured incorrectly on the host, what is the impact on communications? | messages addressed to hosts on remote networks cannot be delivered |
| What does a router do with a packet if it cannot determine where to forward a message? | It drops it |
| If a router receives a packet that it does not know how to forward, what type of route must be configured on the router to prevent the router from dropping it? | Default route |
| If the router must forward a packet to another router, what address will it read? | the MAC address of the connected router |
| What device has multifunction capabilities like a router with switching functionality and a wireless access point? | integrated |
| What is the acronym for an integrated services router? | ISR |
| What command will display the current IP configuration in MS Windows? | ipconfig /all |
| By default, in WINXP, is Simple File Sharing enabled? | Yes |
| What is a reason for disabling simple file sharing? | To assign specific permissions |
