Please respond to BOTH of the following prompts.Question AWhat are the most common
wireless technologies in use today on computer networks, and what capabilities do they
provide that increase mobility?Question BWhat is the difference between asynchronous and
synchronous network connections, and why is it important to know the
difference?ANSWER THE ABOVE DISCUSSION TO BOTH QUESTIONS, THEN REPLY TO
CLASSMATE DISCUSSION EXPLAINING WHY YOU
AGREE. CLASSMATE’S DISCUSSIONQuestion AThe most common
wireless technologies existing today are a mix of wireless LANs (WLAN), cellular (4G/5G),
and Bluetooth. All of these utilize various segments of the radio frequency spectrum but all
allow mobility to a degree in their implemented use for information systems. Wireless LAN
technologies (B, G, N, AC, and the latest AX) allow for network convergence within a small
area or a corporate campus through the use of bridges and/or repeaters (e.g. Cisco Meraki
routers) that allow for one to travel vast spans without the need to re-connect to a different
network. Cellular wireless technologies have increased in capabilities and accessibility,
allowing not only phones, but smart devices and vehicles to communicate wireless to
provide things like tracking and health/maintenance/wellness reports. Bluetooth, though
limited in distance (approx. 30 feet) allows for ease of device connectivity that can also
assist in increasing productivity by wirelessly connecting to these various devices. Question
BAsynchronous connections are comprised of singular bytes of data that when combined
with start, stop, and an error checking parity bits that make up a data packet frame that is
then sent in a half-duplex means to a distant end and require minimal hardware and/or
software to compute, but because of these extra added bits, make asynchronous
connections slow. Synchronous connections are generally eight bits in length, are comprised
of a starting sequence flag, control byte (information about data and/or status of
sender/receiver), address byte (identifies the frame destination), the actual data being sent,
followed by a cyclic checksum (ensures the frame is recompiled in the correct sequence),
and a stop flag byte. These synchronous connections are also more efficient than the
previous because of the composition structure and how the distant-end can
read/understand them faster without waiting for the next packet to arrive in a full-duplex
manner. Because of this, it’s important to note which connection type being utilized will
support a function, application, or codec to avoid latency or other performance issues.
