What would you like to do?

When both multiplexers a and b combine four 100 kbps channels using a time slot of 4 bits each frame generated from a and b has the size of 16 bits the frame at c is 32 bits what is the frame rate at?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Frames of 1000 bits are sent over a 1-Mbps channel using a geostationary satellite whose propagation time from the earth is 270 msec Acknowledgements are always piggybacked onto data frames The head?

Let t=0 denote the start of transmission.At t=1 msec,the first frame has been fully   transmitted.At t=271 msec,the first frame has fully arrived.At t=272 msec,the frame 

Channel has data rate of 4 Kbps and propagation delay of 20mswhat range of frame size do stop and wait give an efficiency of atleast 50?

You need to use two formulas - firstly a= propagation delay/transmission time. We'll denote this by tprop and ttrans.  tprop is given in the question, it is 20 x 10-3 ttrans

Comparison between windows 16 bit 32 bit?

  Most modern operating systems are either 32 bit or 64 bit but it mostly has to do with memory coding. 32bit can utilize a maximum or 4gb or RAM due to the amount of nu

Consider a logical address space of eight pages of 1024words each mapped onto a physical memory of 32 frames how many bits are there in the logical address?

  As was given for a 4 Page, 1024 words & 64 frames (shown below) 4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2

What is bit interval and bit rate?

Bit Interval: The time required to send one signal bit. Bit Rate: The number of bits that are conveyed or processed per unit of time. (Example: 100MB/sec)

How do you use 8 bit register as 16 bit register?

8 bit registers cannot be used as 16 bit registers. The reverse works, however, as the 16 bit general purpose registers of the 8086 and 8088 can be used as pairs of 8 bit regi

How much time in a Bluetooth one-slot frame is used for the hopping mechanism?

1) one-slot frame in the Bluetooth transmitter hops is between 791-MHz wide channels with 1600 hops per second.and other hand, 802.11b/g uses the listen-before-talk mechanism.
