Answer:
Port 443
Explanation:
This is the Hypertext Transfer Protocol Secure that combines the HTTP with a cryptographic protocol, which can be used for payment transactions and other secure transmission of data from Web pages. Whenever you connect to a website beginning with "https://" or you see the lock icon, you’re connecting to that web server over port 443.
 
        
             
        
        
        
Answer:
Interactive voice response
Explanation:
Interactive voice response (IVR) is a technological innovation which allows computer systems to interact with individuals with the use of voice and Dual-tone multi-frequency signaling (DTMF) tones input through a keypad. In telecommunications sector, IVR enables customers to interact with a company’s host system through the use of a telephone keypad or by using speech recognition, after which services can be accessed by the use of the IVR dialogue.
 
        
             
        
        
        
Answer:
The answer is True
Explanation:
Switches are responsible for connecting computers within a network and it belongs only to its local network. Its responsibility is to filter and forward packets between LAN segments. They operate on layer two (2) and sometime layer three (3) of the OSI Model.
Routers on the other hand, are responsible for the interconnections of two or more networks. They forward data packets between networks. They reside at gateways, exactly where two or more networks connects. And they use communication protocols to effectively and efficiently communicate among two or more host.

Answer:
It is not possible.
Explanation:
In this example, we need to accommodate 473 computers for six clients that are 473 IP addresses.
For this request just we have /22 IPv4 address blocks, this mean
22 red bits 11111111111111111111110000000000 <--- 10 host bits
We must increase red bits to 25, we need these 3 bits to create 6 sub red, in this case, 2^3 = 8 sub red.
Why did we ask 3 bits? Because if we ask only 2, 2^2 = 4, and we need 6 sub red.
25 red bits 11111111111111111111111110000000 7 host bits 
In this case, we need more than 260 computers, but just we have 7 bits, this means.
2^7 = 128 and just one customer needs 260, for that is impossible.
