Term
|
Definition
| multiple input, multiple output antenna technology - biggest development for 802.11n (key to higher speed and range) via multiplexing |
|
|
Term
|
Definition
| technique that combines multiple signals for transmission over a single line or medium |
|
|
Term
|
Definition
| bonding channels increases the wireless transmission rate |
|
|
Term
|
Definition
| orthogonal frequency division multiplexing - a transmission strategy used as a digital multicarrier modulation method in which a large number of closely spaced othogonal subcarrier signals are used to carry data on several parallel data streams or channels |
|
|
Term
| Describe spread spectrum-frequency hopping |
|
Definition
| data signals either alternate b/w carrier frequencies or constantly change their data pattern |
|
|
Term
| Describe direct sequence spectrum-frequency hopping |

Term

| direct-sequence spread-spectrum technology |
|
|
Term
|
Definition
| can transmit more than 1 spatial stream at the same time but they are directed to a single address |
|
|
Term
|
Definition
| allows an AP to sned multiple frames to multiple clients at the exact same time - thus allowing the AP to act like a switch instead of just a hub |

Term
| What does physical topology refer to? |
|
Definition
| the actual layout of the computer cables and other network devices |
|
|
Term
| what does a logical topology refer to? |
|
Definition
| the way in which the network appears to the devices that use it |
|
|
Term
|
Definition
| it uses a trunk or backbone to connect all the computers on the network |
|
|
Term
| Describe a logical ring topology |
|
Definition
| the data travels in a circular fashion from one computer to another on a network (it is not a physical ring) |
|
|
Term
| Describe a true ring topology |
|
Definition
| if a single computer or section of cable fails the signal is interrupted (faults)/ the entire network becomes inaccessible |
|
|
Term
|
Definition
| the presence of a primary and a back-up ring |
|
|
Term
|
Definition
|
|
Term
| describe a token ring network |
|
Definition
| a MSAU (like a hub or switch) performs the token circulation internally. the ring-in port on each MSAU is connected to the ring-out port of another. the last MSAU is then connected to the first to complete the ring. |
|
|
Term
|
Definition
| all computers and other network devices connect to a single central device (hub/switch) - requires point-to-point connection b/w device and hub |
|
|
Term
| Describe wired-mesh topology |
|
Definition
| each computer on the network connects to every other, creating a point-to-point connection b/w every device on the network - this provides the highest level of redundancy |
|
|
Term
| define the word topology by itself |
|
Definition
| refers to the way a network is laid out both physically and logically |
|
|
Term
|
Definition
| used in a bus topology to connect each computer to the trunk/backbone |
|
|
Term
| How does a bus topology avoid signal reflection? |
|
Definition
| by requiring each end of the physical bus be terminated with one end also being grounded |
|
|
Term
| does a bus topology require either a hub or a switch? |
|
Definition
|
|
Term
| what is IEEE 802.3 ethernet standard |
|
Definition
| the most common implementation of a linear bus topology |
|
|
Term
| a bus network that has missing or loose terminators results in what? |
|
Definition
| disrupted data transmissions |
|
|
Term
| does a ring topology require a hub or switch? |

Term
| describe an infrastructure wireless topology |
|
Definition
| uses LAN, access points, and wireless access points |
|
|
Term
| describe ad hoc wireless topology |
|
Definition
| point-to-point connections between personal devices usually on a home network or temporary connections used for media streaming, etc. |
|
|
Term
| describe a wireless mesh topology and its advantages |
|
Definition
| uses a wireless base station (AP) attached to a wired network - self healing, scalable, reliable, and cost effective |
|
|
Term
|
Definition
| near field communication used in RFID and Wi-Fi |
|
|
Term
| Advantages of infrared technology |
|
Definition
| good speeds up to 16 mbps, uses less power/batteries, secure against eavesdropping and signal tampering, no RFI issues or signal conflict, and it replaces cables |
|
