QUESTION 1:

Your computer received the following digital, binary signal sequence. Now, your computer should cover the binary data to the text so you would read it on your computer screen. Assume, the received binary code was generated based on ASCII.

Received binary data:

01001001 01010100 00110101 00110000 00110101 00100000 01010111 01101001 01101110 01110100 01100101 01110010 00100000 00110010 00110000 00110010 00110011 00100000 01010111 01010101 01010011 01010100 00100000

You should write the text that will appear on your computer screen. Simply convert the binary data to text.

HNIT: Do your web search and find (Binary to Text Translator) to convert the binary to back to text.

QUESTION 2:

The user would like to save the incoming binary that you decoded in question 1. Therefore, the user would like to make sure there is enough memory space in his/her computer. What would be the minimum memory space (in Bytes) required to save the incoming data?

QUESTION 3:

Develop the Manchester Code for the first character of the digital data stream in question 1. You should develop Manchester Code for 01001001

Your name must be on the digital signal code diagram

QUESTION 4:

In an airport, two computers in two different terminals will be in communication-based on the requirements below;

The user in terminal 1 and the receiver terminal 2 can operate on different clock frequencies.

The speed of the communication is not a concern; however, the quality of the communication is important.

The terminals are more than 100 meters apart. There is a heavy external electrical noise which would impact and disrupt the communication and cause miscommunication (corrupted message) between terminals

4a)

What would be your preferred data transmission technique? Synchronous or Asynchronous transmission. Explain your answer

4b)

What kind of Error Detection method you would use to make sure you will detect most of the communication errors? Explain your answer

QUESTION 5:

There are three given different communication cases. Where a user would like to access a database.

CASE 5-1: The user computer is on a transatlantic cruise ship and the receiver (the database) is in NYC.

a) What type of communication (digital or analog) would you use between given to communication points?
b) If it is digital then write the cable type you would use, if it is analog then write the wireless communication type you would use.
CASE 5-2: The computers are in different cities. The user computer is in Los Angeles and the receiver (the database) is in NYC. This has to be a fast and secure communication

a) What type of communication (digital or analog) would you use between given to communication points?
b) If it is digital then write the cable type you would use, if it is analog then write the wireless communication type you would use.
CASE 5-3: Both computers are in the same building. The user computer is on the second floor and the database is on the third floor.

a) What type of communication (digital or analog) would you use between given to communication points?
b) If it is digital then write the cable type you would use, if it is analog then write the wireless communication type you would use.
