Which type of communication medium provides the highest bandwidth and can highly protect the data transmission against EMI and RFI?

Light can only be coupled to a fiber at its entry points. The main advantages of optical fiber communication over electrical cable transmission is its high bandwidth capability (almost 10Gps) over long distances due to the extremely low loss at same specific wavelengths (e.g. 1.3 um and 1.55 um).

Which of these is the most secure way of data transfer?

The most secure option is end-to-end encryption (E2EE), where even the service provider cannot decrypt data shared through it. For smaller organizations, an E2EE messaging service, like Signal or Wickr, may be sufficient.

What is the most secure file transfer protocol?

Five Secure File Transfer Alternatives to FTP

  • SFTP. SFTP allows organizations to move data over a Secure Shell (SSH) data stream, providing excellent security over its FTP cousin.
  • FTPS. FTPS, known as FTP over SSL/TLS, is another option for businesses to employ for internal and external file transfers.
  • AS2.
  • HTTPS.
  • MFT.

Why is guided media more reliable than unguided medium?

Three reasons due to which the guided communication medium is more reliable than the unguided medium is mentioned below : The major advantage of the guided media is that they have got the higher bandwidth range than the unguided media. It’s the most used light weight media which is handled in a very flexible manner.

What kind of security does a medium security prison have?

First, let’s talk about how beefy this lock truly is. With a 9/16″ shackle and 80mm body, this lock is a force of nature.

Which is the most secure fiber optic or copper cable?

Fiber-optic is the most secure because it cannot be tapped like the other three copper-based cables; it does not emit EMI. Although shielded twisted-pair (STP) offers a level of security due to its shielding, it does not offer a level of security like that of fiber-optic.
