On occasion, a company will create a protocol that, while not an official standard,
becomes so popular that other companies start using it. - ANSWER:T
One of the latest interface standards is the RS-232 interface. - ANSWER:F
An EIA-232F interface is a full-duplex connection. - ANSWER:T
Because USB provides a digital interface, it is necessary to convert the digital signals
of the microcomputer to analog signals for transfer over a connection. - ANSWER:F
When using peripherals that are designed with a USB connector, it is also possible to
connect one USB peripheral to another. - ANSWER:T
USB is an example of a full-duplex connection. - ANSWER:F
The procedural component of USB is probably the most involved of the four
components. - ANSWER:T
FireWire is similar to USB in that it is hot pluggable. - ANSWER:T
To take advantage of the higher-speed interface of SCSI, you need to install a SCSI
adapter in your computer. - ANSWER:T
Rather than being a single shared bus, InfiniBand is a network of high-speed links
and switches. - ANSWER:T
An asynchronous connection is the most complex example of a data link protocol. -
ANSWER:F
A start bit is always a 1. - ANSWER:F
A stop bit is always a 0. - ANSWER:F
The starting and ending sequences of the synchronous connection are called flags. -
ANSWER:T
Because of their higher efficiency, asynchronous connections have almost
completely replaced synchronous connections. - ANSWER:F
, Examples of real-time applications usually include streaming voice, video, and music.
- ANSWER:T
Neither USB nor FireWire support isochronous connections. - ANSWER:F
If control simplicity is your primary goal, point-to-point connection of terminals is
clearly superior to multipoint connections. - ANSWER:T

at the ____ layer. - ANSWER:physical
3. An interface standard can consist of four parts, or components: the electrical
component, the mechanical component, the ____ component, and the procedural
component. - ANSWER:functional
4. The ____ component of an interface deals with items such as the connector or
plug description. - ANSWER:mechanical
The ____ component of an interface describes how the particular circuits are used to

6. In modem interfacing terminology, the computer (or terminal) end of an interface
is referred to as ____. - ANSWER:data terminating equipment (DTE)
7. In modem interfacing terminology, the modem is referred to as the ____. -
ANSWER:data communicating equipment (DCE)
8. To define functional and procedural components, EIA-232F incorporates the ITU's
____ standard. - ANSWER:V.24
9. A ____ connection is one in which both sender and receiver may transmit at the
same time. - ANSWER:full-duplex
10. Some systems, for various reasons, allow only one side or the other to transmit
at one time. This type of connection is an example of a ____ connection. -
ANSWER:half-duplex
11. The idea behind ____ is that the peripheral can simply be plugged in and turned
on, and that the computer should dynamically recognize the device and establish the
interface. - ANSWER:hot plugging
12. The ____ component of USB strictly specifies the exact dimensions of the
interface's connectors and cabling. - ANSWER:mechanical
