QUESTION 1: The final destination of the communication, received the following digital/ binary signal sequence. Now, your computer should cover the binary data set to the text so you would be able to see and read it on your computer screen. Assume, received binary code was generated based on ASCII. You should write the text that will appear on your computer screen
01010111 01010101 01010011 01010100 00100000 01001001 01010100 00100000 00110101 00110000 00110101 00100000 00100000 01010011 01110101 01101101 01101101 01100101 01110010 00100000 00110010 00110000 00110010 00110010 00100000 01000100 01110010 00101110 01001101 01110101 01110100 01101100 01110101 00100000
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 the question 1. Therefore, the user would like to make sure if there is enough memory space in his/her computer. What would be minimum memory space (Bytes) required to save the incoming data?
QUESTION 3: Develop the Manchester Code for the first section of digital data stream in question 1. You should develop Manchester Code for 01010111 . Your name must 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;
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, 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 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 to a database.
CASE 1: Both computers are in the same building. User computer in the second Floor and the database in the third floor.
a) What type of communication 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 the write the wireless communication type you would use?
CASE 2: The computers are in different cities. User computer is in the Los Angeles and receiver is in NYC. This has to be fast and secure communication
a) What type of communication 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 the write the wireless communication type you would use?
CASE 3: User computer is on transatlantic cruise ship and receiver is in NYC.
a) What type of communication 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 the write the wireless communication type you would use?

BUSINESS CASE: The Hospital information system has been in use to furthering the Hospital Network’s efforts to become more competitive.
Main Parameters of the Hospital system :
There are three buildings are in three different cities
Hospital Building in City 1 : 150 Patients Room , and 25 offices
Hospital Building in City 2 : 95 Patients Room, and 15 offices
Hospital Building in City 3 : 80 Patients room, and 30 offices
All buildings have their own IT Data center.
IT system Hardware: Personal PCs , Server, Cables, Memory , Printer , X-ray , Big screen monitors , card readers , Scanners
IT system Software: MS Office, Financial /Accounting,
IT system Databases: Database for Patients, Database for Doctors, Database for Building, Database for Employees
IT system Network: Internet and Dedicated data communication lines between all four Buildings.
Dedicated data communication lines between all Buildings are private fiberoptic communication lines
Supplier Companies: Blood Test Lab, Bank, Medical Equipment Supplier, Medication Supplier.
QUESTION 1 : You were given the following LAN in one of the hospitals . You should list the device and TCP/IP layer(s) that has been in used in each device on this network
You would write the name of device and the TCP/IP layer(s)layer in that device .
QUESTION 2: Develop a network diagram illustrate the key elements that of the Hospital IT network that include following two different connections types.
a) Each Building has the Internet communication from local Internet service provide (ISP) . So it will communicate with local supplier companies and local patients
b) There is a dedicated data communication lines (fiber) among all three Buildings to prove access to all databases from each hospital.
This private connection is not open to public to use.
QUESTION 3:
The hospital IT system has dedicated Fiber data communication lines among all three Buildings. On Monday morning, one of the fiber optic cable was damaged by a construction company. Telcom Company informed the Hospital that, it will take a week to repair the fiber cables. But the Hospital cannot wait one week to do business-to-busses transactions among all three Buildings. No fiber communication one week is a big problem.
