Assignment

Question No 1: Marks 10

Q1.Suppose data is being transferred between two cell phones via blue tooth. You are required to answer the following questions with proper reasoning:

1. What will be the line configuration between them? (Point to point or Multipoint).
2. What will be the relationship between the cell phones? (Peer to Peer or Primary Secondary)
3. Which type of communication will it be? (Local or Remote communication)
4. What will be the medium of communication? (Wireless or Wired)

Question No 1: Marks 10
Suppose data is being transferred between two cell phones via blue tooth. You are required to answer the following questions with proper reasoning:
What will be the line configuration between them? (Point to point or Multipoint).
What will be the relationship between the cell phones? (Peer to Peer or Primary Secondary)
Which type of communication will it be? (Local or Remote communication)
What will be the medium of communication? (Wireless or Wired)
Answers:
What will be the line configuration between them? ( Multipoint).
What will be the relationship between the cell phones? (Peer to Peer )
Which type of communication will it be? (Local communication)
What will be the medium of communication? (Wireless )

Q.2: Suppose computer A is connected to another computer B by a passive hub at home. You are required to mention the type (LAN, MAN or WAN) of this computer network? Support your answer with reason?
1) Geographical area:
As we knew that, A and B computer connected with each other at home, it's one good reason to understand that, our network is Local area network LAN. Because local area network always restricted to limited geographical area like home, work station, building etc.
2) Passive Hub:
if we talk about passive hub, it is central connecting device in network that act as a point contact for wires from numerous stations. But it doesn't coordinate as a signal regeneration or processing of signals. So it's second good reason to understand that, we are under local area network LAN. Suppose that, we are in WAN or MAN network, definitely we need to regenerate signal to maintain network effectiveness . But here we are using passive hub, so we are in Local area network.

Q.3: Identify the following transmission modes as simplex, half duplex or full duplex.
a. Walkie talkie (Half-Duplex)
b. Telephone conversation (Full-Duplex)
c. A person talking into microphone (Half-Duplex)
d. Viber calling (Half-Duplex) 
e. TV broadcasting (Simplex)

Q.2: Suppose computer A is connected to another computer B by a passive hub at home. You are required to mention the type (LAN, MAN or WAN) of this computer network? Support your answer with reason?


1) Geographical area:
As we knew that, A and B computer connected with each other at home, it's one good reason to understand that, our network is Local area network LAN. Because local area network always restricted to limited geographical area like home,work station, building etc.


2) Passive Hub:

But it doesn't coordinate as a signal regeneration or processing of signals. So it's second good reason to understand that, we are under local area network LAN. Suppose that, we are in WAN or MAN network, definitely we need to regenerate signal to maintain network effectiveness . But here we are using passive hub, so we are in Local area network.


Q.3: Identify the following transmission modes as simplex, half duplex or full duplex.
a. Walkie talkie (Half-Duplex)
b. Telephone conversation (Full-Duplex)
c. A person talking into microphone (Half-Duplex)
d. Viber calling (Half-Duplex) *** But NOT Sure
e. TV broadcasting (Simplex)

 CS601 Assignment No 1 Idea Solution May, 2014

Q.3: Identify the following transmission modes as simplex, half duplex or full duplex.
a. Walkie talkie (Half-Duplex)
b. Telephone conversation (Full-Duplex)
c. A person talking into microphone (Simplex)
d. Viber calling (Full-Duplex)
e. TV broadcasting (Simplex)

because in the walkie talkie transmission have cover some area in which you can talk. If you cross that limited area you cant talk each other..

c. A person talking into microphone (Simplex),,

i think ye half duplex hy ,,a'm right? plz tell me if a'm wrog or right...

bcoz a person hy koi or communication nhi kr raha is k sth so half duplx ho ga na,,,??

plz jaldi reply krain agr kisi ko confrm pata hy to.

@vu student bcs*iiii, Simplex, because its' absolutely one way communication... other side is not capable to communicate back 

simlex = one side communication like tv , microphone

half duplex = 2 side communication but one by one like walki talki , over and out army communication

full duplex = 2 side communication at the same time like telephone

plzzzzz Viber call ka cnfirm bta den k simplex h ya half duplex

@Iffi raja, Viber calling is (Full-Duplex)
