Q1) Explain what is meant by personal area network-to-workstation connections.
Answer: The personal area network was created in the late 1990s and is one of the newer forms of computer networks.Using wireless transmissions with devices such as personal digital assistants (PDAs),laptop computers,and portable music players,an individual can transfer voice,data,and music from handheld devices to other devices such as microcomputer workstations.Likewise,a user can download data from a workstation to one of these portable devices.For example,a user may use a PDA to record notes during a meeting.Once the meeting is over,the user can transmit the notes over a wireless connection from the PDA to his or her workstation.The workstation then runs a word processor to clean up the notes,and the formatted notes are uploaded to a local area network for corporate dissemination.
Q2) ____________________ are sets of rules used by communication devices.
Answer: Protocols
Q3) The ____________________ protocol suite incorporates the TCP and IP protocols and has in fact always been more popular than the OSI model.
Answer: TCP/IP
Q4) A(n)____________________ converts the local area network data into wide area network data.
