Answer:
The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out stored program instructions.
Explanation: The control unit does not execute program instructions rather, it directs other parts of the system to do so.
Answer:
systems used by many providers require customers to share bandwidth with neighbors
Explanation:
One of the disadvantages of cable technology is that systems used by many providers require customers to share bandwidth with neighbors. This ultimately causes many problems since cables would need to be extended to reach every single user that will be sharing the bandwidth. This would mean cables all over the place. Also, it is very difficult to limit the bandwidth per person, meaning that if anyone is using up all of the bandwidth through the cable, the rest of the individuals connected would not have the bandwidth that they need or are paying for.
Answer:
Embedded technology is a technology that exists inside another device.
Some protocols have multiple algorithms to choose from for e.g., cryptographic purposes. During connection set up, client and server negotiate which one they'll use.
One example is the set up of a TLS connection. During the handshake, the client shares a list of its supported ciphers (the 'ciphersuites'). The server responds by indicating the best one that both sides support.
