Question

Answer the following review questions in short.

1. Compares the advantages and disadvantages of the Universal Serial Bus to those of the EIA-232F interface.

2. What is the major advantage of the Thunderbolt interface over the Universal Serial Bus interface?

3. If I have a device that has a Universal Serial Bus 3.0 interface, but my computer only has a Universal Serial Bus 2.0 connector, is my device going to work? Explain why or why not.

4. Show the sequence of start, data, and stop bits that is generated during asynchronous transmission of the character string ALI, consider even parity . (Binary Value A= 01000001, L= 01001100, I= 01001001

5. List two examples of the half-duplex and full-duplex connection.

6. Terminals A, B, and C are connected to a mainframe computer. Only terminal C has data

to transmit. Show the sequence of messages sent between the mainframe and the three

terminals using roll-call polling.

7. Using the same scenario as in the previous problem, show the sequence of messages

exchanged using hub polling.

8. List two features of the asynchronous connection that allow the receiver to stay in sync

with the incoming data stream.

9. How does the receiver in a synchronous connection stay in sync with the incoming data

stream?
10. What types of devices are best served with an isochronous connection?

Explanation / Answer

1)Universal series bus is quicker,

easier and

simple to install

......................................................................................................................................................................

2) Thunder blot is quicker ,it offers a 10 Gbps connection speed for the peripheral devices

universal series bus offers a 4.8Gbps

...................................................................................................................................................................

3)yes, the device is going to work.the 3.0 interface was drop back not quicker 3.0 interface speed.

.....................................................................................................................................................................

5)half duplex connection: 1.CB Radio

2.Ham Radio

full duplex connection: 1.telephone systems

2.cable modems

......................................................................................................................................................................

6) Mainframe polls A

A responds No

Mainframe polls B

B responds No

Mainframe polls C

C responds data

Mainframe acknowledges Data

Note: since given C only transmits data rest of all are no data is transmitted.

......................................................................................................................................................................

7) Mainframe polls A

A passes polls onto B

B passes polls onto C

C acknowledges data [since the data transmitted by only C]

.....................................................................................................................................................................

8) Features : 1.Start bit

2.short Frame

Are the two features of asynchronous connection that permit the receiver to stay in sync with the incomimg data system.

.........................................................................................................................................................

9) A seperate clock signal ,utilization of Manchester kind code ,or few form of internal analog signal sampling through a bulit-in synch model.

......................................................................................................................................................................

10) real time devices like video cameras
