Quiz 3 Flashcards
which type of transmission synchronization technique uses start and stop bits at the beginning and end of a data frame?
Asynchronous
There are three methods of performing synchronization: isochronous, asynchronous, and synchronous. When you are using an asynchronous technique, the data frame is encased within a start and stop bit, which lets the receiver know of its location within a traffic stream.
What is the name that is used to reference the central primary cable distribution point in a building?
MDF
The main distribution frame (MDF) is the primary distribution point for the cabling in a building. Multiple intermediate distribution frames (IDFs) may exist throughout the building as smaller distribution points (that is, per floor)
Which category of fiber optic media can carry a signal for the longest distance?
Single mode has a longer distance specification
Which type of fiber-optic cabling only allows an individual light path through it?
Single-mode
Single-mode cabling has a very small interfiber core that only allows a single mode (path) of light between the transmitter and the receiver.
What is a crimper?
A crimper can be used to attach a connector to the end of a UTP cable.
What type of connector is often used for cable TV connections?
F-type
An F-connector of F-type connector is often used for cable TV connections.
For home automation hubs, what wireless communication protocol is commonly used for home automation, creating a mesh network of appliances, thermostats, and door locks?
Z-Wave is a wireless communications protocol used primarily for home automation. It creates a mesh network using low-energy radio waves to communicate from appliance to appliance. Z-Wave is found in devices such as lighting control systems, security systems, thermostats, windows, locks, swimming pools, and garage door openers.
What fiber type would you use if the requirements to be met included a SMF media type, 1Gbps bandwidth capacity, and a distance limitation of 5 km?
1000BASE-LX uses single-mode fiber (SMF), has a bandwidth capacity of 1Gbps, and a distance limitation of 5 km.
Which two standards are both used as color code guides for a crossover cable?
TIA/EIA-568b or b standard
TIA/EIA-568a or a standard
What is a common cable management component for terminating fiber connections?
A fiber distribution panel is often used in the fiber media environment for terminating media.
