Too much for this forum. Look for a night course on telephone technology.
They are essentially crosspoint switches with touch-tone decoders.

What is the area of a cinder block in square feet?
Standard block is basically 8" x 16" which is 128 square inches 128/144=0.8888888888888889. The size of the mortar joints will also have a bearing on the overall wall size.

Which parameters and design choices determine the actual algorithm of a Feistel cipher?
Block size: Larger block sizes mean greater security but reduced encryption/decryption speed. A block size of 64 bits is a reasonable tradeoff and has been nearly universal in block cipher design. However, the new AES uses a 128-bit block size.Key size: Larger key size means greater security but may decrease encryption/decryption speed. Key sizes of 64 bits or less are now widely considered being inadequate and 128 bits has become a common size.Number of rounds: The essence of the Feistel cipher is that a single round offers inadequate security but that multiple rounds offer increasing security. A typical size is 16 rounds.Sub key generation algorithm: Greater complexity in this algorithm should lead to greater difficulty of cryptanalysis.Round function: Again, greater complexity generally means greater resistance to cryptanalysis.
How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
What is 167 in decimal expressed in binary?
To express a number in binary, first we find the greatest power of 2 which is less than or equal to the value. The first powers of 2 are: 1, 2, 4, 8, 16, 32, 64, 128, 256, ... The highest value we will use here is 128 (the 7th power of 2). So far we have: 10000000 (binary) = 128. Next we need to subtract 128 from 167 to find the remaining value. 167 - 128 = 39. The next value we should use is 32 because it is the largest value still less than or equal to 39. Now we have: 10100000 (binary) = 128 + 32 = 160. 39 - 32 = 7, so now we choose a 4. 10100100 (binary) = 128 + 32 + 4 = 164. Now a 2 and a 1 will finish the process. 10100111 (binary) = 128 + 32 + 4 + 2 + 1 = 167.
