Consider the message to be transmitted is the first letter of your last name. Using ASCII code 7-bit
given in Table 1 below, encode the message to digital signal transmission using the following
1.The network access layer is concerned with
The exchange of data between the end system and the network to which it is
attached. The sending system must provide the network with the address of the destination
system, so that the network may route the dat
1- Explain why:
a. In satellite communications the uplink and downlink frequencies must be different.
A satellite must use different uplink and downlink frequencies for continuous
operation in order to avoid interference.
b. A satellite uplink frequency i
1- Compare between TCP/IP and OSI Protocol Architectures.
Transmission Control Protocol (TCP) and Internet Protocol (IP) these are the two
standard protocol we used to connect with computer network using internet. These protocol

Square wave: It is a non-sinusoidal periodic waveform which can be represented as an infinite
summation of sinusoidal waves, in which the amplitude alternates at a steady frequency between
fixed minimum and maximum values, with the same duration at min
1. Periodic Signals:A signal which is repeats itself is called as or known as periodic signal, for a continues time

The three important characteristics of the perio
1- Why the square waves (digital signal) have an infinite bandwidth?
Recurrence is the quantity of cycles every second. I have seen before the recipe that
Transmission capacity = Maximum Frequency Minimum Frequency. It told once in a while
1- What are the three important characteristics of a periodic signal?
In Fig. 1 below, if s(t) = A sin (2ft + ) find A, f, and

Q. Suppose we wish to transmit blocks of data of length k bits. Instead of transmitting each
block as k bits we map each k-bit sequence into a unique n-bit codeword.
For k = 2 and n = 5
