Answer:

Explanation:

C.argv[0]: "program.py"

argv[1]: "-r"

argv[2]: "input.dat"

argv[3]: "output.dat"

is the right answer. as 0 argument is always the script. We can find this by importing sys and using the command sys.argv. And like len(sys.argv) will give total number of arguments.

Binary is a base-2 number system instead of the decimal (base-10) system we are familiar with. Write a recursive function PrintI

Paladinen [302]

Answer:

In C++:

int PrintInBinary(int num){

if (num == 0)

return 0;

else

return (num % 2 + 10 * PrintInBinary(num / 2));

}

Explanation:

This defines the PrintInBinary function

int PrintInBinary(int num){

This returns 0 is num is 0 or num has been reduced to 0

if (num == 0)

return 0;

If otherwise, see below for further explanation

else

return (num % 2 + 10 * PrintInBinary(num / 2));

}

----------------------------------------------------------------------------------------

num % 2 + 10 * PrintInBinary(num / 2)

The above can be split into:

num % 2 and + 10 * PrintInBinary(num / 2)

Assume num is 35.

num % 2 = 1

10 * PrintInBinary(num / 2) => 10 * PrintInBinary(17)

17 will be passed to the function (recursively).

This process will continue until num is 0

Explain benefits and disadvantages of using BNC over F-Type connectors on coaxial cables

Leokris [45]

Answer:

The benefits and disadvantages of using BNC over F-Type connectors on coaxial cables are;

The benefits of the BNC includes;

1) Easy connect and disconnect for a more rapid connection unlike the F-Type connector which is a screw connector

2) Reduction on stress on the termination of the coaxial cable

3) Appropriate in systems that see frequent reconfiguration unlike te F-Type connector that is permanently attached

4) Prevent unwanted disconnection ensuring image consistency by locking into place

5) Can extend to 300 ft.

The disadvantages of the BNC connectors are;

1) A separate power supply for the cable is required

2) Is used only for video transmission

3) Cannot be used for audio

4) The center wire is not easily visible like those of the F-Type connector which serves as a pin

5) The BNC connector is not watertight like the F-Type connectors

6) There are no provision for properly and securely attaching the cable to the camera for field work such that it can be easily disconnected while in use unlike the F-Type connectors

7) It is not as easy to manufacture like the F-Type connector and it is more expensive

8) The installation of the BNC connector on a coaxial cable is more intricate and the center cable is hidden from view after the BNC is attached thereby making it not possible to see if there is an error in installation which is unlike the F-type connector that takes less than 30 seconds to be attached to a cable

9) The F-Type connector provides more cost savings during installation than the BNC connector

Explanation:

The BNC connector is a type of bayonet connector used more frequently on CCTV systems. The benefits of the BNC includes;

The F-Type connectors are usable on SATV, CATV, and Digital TV where they are used together with RG6 or RG11 cables
