Hi dears,

Give a brief account of digital to digital conversion? Explain each heading or term in a sentence or two (be to the point).

Sincerely,

Ahmad Raza

Briefly explain the following terms in two or three sentences?

• Periodic Signal.
• Sine wave.
• Phase.
• Composite signal.
• Fourier Transform.
• Bandwidth.
• Encoding Digital Signal.
• Modulating a digital signal.
• Modulating an analog signal.
• Digitizing an analog signal.

Hi,

Describe the encapsulation process in the OSI reference model? Give Proper Answer don't give very long answer.

Thanks.

How can i post more posts at blogger. I can post more posts at Home page but i don't know if i create another page then how can i add more posts at another pages in Blog.

I know how can i post more posts at home page but i don't know how can i post more posts at other pages that is created in blogger.

Please tell me pictorially.

The following questions deal with CRC error detecting code. Given a message M = 110100, determine the CRC using the polynomial P = x3 + 1. What is the transmitted message T? Perform the error checking at receiving end.

Two signals have the same frequencies.

However, whenever the first signal is at its maximum amplitude, the second signal has amplitude of zero.

What is the phase shift between the two signals?

Differentiate and make them clear? Please brief and concise answers in three to four sentences?

Differentiate and compare between the followings:

1. Syntax and semantics of a protocol.
2. Performance and reliability of a network.
3. Spatially shared and time shared in multi point line configuration.
4. Circuit switch and packet switch network.

Hi,

What are the asynchronous protocols in data link layer? Discuss in detail with examples

Hi,

i need answer of this question answer should be proper. What kind of errors are undetectable by the checksum?

Thanks
