Answer:
Quantizing error
Explanation:
In digitisation of analog signal refers to the rounding off of values which are approximately equal to the analog signals. The method of sampling chooses a few point on the analog signal and then these points are joined to round off the value to a near stabilised value. such process is known as Quantization. For any system, during its functioning, there is always a difference in the values of its input and output. The processing of the system results in an error, which is the difference of those values.
The difference between an input value and its quantized value is called a Quantization Error. A Quantizer is a logarithmic function that performs Quantization rounding off the value. An analog-to-digital converter (ADC) works as a quantizer.
Answer:
1. SSH/Telnet.
2. SMTP.
3. DNS.
4. DHCP.
5. HTTPS/SSL.
6. FTP
Explanation:
1. Provides connections to computers over a TCP/IP network: the standard protocol used for this is SSH/Telnet, through port number 22 and 23 respectively.
SSH is acronym for secure shell.
2. Sends e-mail over a TCP/IP network: SMTP using port number 25.
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
3. Translates URLs to IP address: DNS using port number 53.
A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.
4. Automates assignment of IP address on a network: DHCP using port number 67.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
5. Securely transports web pages over a TCP/IP network: HTTPS/SSL using port number 443.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
6. Transports files over a TCP/IP network: FTP using port number 20 or 21.
FTP is an acronym for file transfer protocol.
