The term troubleshooting refers to finding a problem and evaluating it so that corrective action can be taken.
Extensive digitization is a process that began in the 1960s.
Networks have more than just a physical component.
International standards-setting bodies can affect standards established in the United States.
A bus topology does not form a closed loop.
The bit interval is the duration it takes a single bit to be transmitted.
Data communications is a subset of telecommunications.
Data can include or convey graphic images, sound, or video files.
The physical layers of the OSI and TCP/IP models are very similar.
The data communications phase associated with digitization is the first phase.
The portion of an IP address from which bits are borrowed when sub netting is the host.
The transport layer ultimately passes data up to the application layer.
A MAC address is associated with the Data Link Layer.
An IP address is associated with Network Layer.
Twisted pair, Coaxial and Fiber Optic are types of cable
The capacity of a circuit to carry data is its bandwidth.
A 32-bit bus can handle four times the data bits as an 8-bit bus.
LAN resources might include software, hardware and data.
Data bits are frequently passed through pins in a connector.Synchronous protocols are the type of data link protocols primarily used to delineate groups of bits or bytes:
A circuit is the link that provides the physical means by which data are transferred.
Circuit configuration affects the way in which two or more communicating devices share their link with each other.
The two basic circuit configuration forms are point-to-point and multipoint.
Five factors are considered when selecting a transmission medium: cost, which should include materials and labor; bandwidth, which determines data speed requirements; security, based on business need; level of transmission impairment that the business can tolerate; and, finally, the distance that the transmission medium will need to cover.
A protocol can be used to determine how devices communicate.
The term “reliable” is mostly associated with TCP.
A topology has more than just physical characteristics.
