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 <em>benefits </em>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 <em>disadvantages</em> 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

When is a wired connection preferred to a wireless connection by an end-user device?

harkovskaia [24]

Answer:

Option (b) When the end-user device will run an application that requires a dedicated connection to the network

Explanation:

Option (b) is the correct option.
When the user device requires a highly dedicated network environment to itself to run a web application that requires large download and upload speeds, bandwidth requirements then it prefers a wired connection than a wireless connection.
If the wireless signal is within the reach, then it advisable to go for a wireless connection than a wired connection. A wired connection requires other hardware equipments like a internet connection cable etc. which is not required in case of wireless connection. So, option (a) is wrong option.
WLAN NIC is a wireless interface network controller that connects to a wireless radio based network than a wired network.So, option (c) is wrong option.
Delay torrent network is designed to operate where continuous network connectivity is not available like extreme terrestrial spaces, space communications, inter planetary communications etc.So, option (d) is wrong option.
