RFC 5322 is a standard that defines the format of internet messages, such as email messages. It specifies the structure and content of email messages, including the headers, body, and attachments. The standard is maintained by the Internet Engineering Task Force (IETF) and is an important reference for anyone working with email or other internet messages. It is also known as the Internet Message Format Standard. Here are a few more points about RFC 5322 − It replaces an earlier standard called RFC 822, which was published in 1982. It is written in ...

In computing, a user agent is a string that a web browser or other client software sends to a web server along with each request to identify itself and its capabilities. The user agent string contains information about the browser version, operating system, device type, and other details that can be used to identify the client. Web servers use this information to tailor their responses to the specific client, such as by sending back content that is optimized for the client's device type or by modifying the layout of the content to better fit the client's display size. The user ... Read More
Overview DNS records (short for "Domain Name System records") are types of data that are stored in the DNS database and used to specify information about a domain, such as its IP address and the servers that handle its email. There are several different types of DNS records, including A records, MX records, CNAME records, and others, each with its own specific purpose. A record (short for "address record") maps a domain or subdomain to an IP address. For example, the domain "example.com" might have an A record that maps it to the IP address "192.0.2.1". When someone types "example.com" ... Read More
Domain Resource Records (DNS records) are entries in the Domain Name System (DNS) that specify the location of a server, the mail server responsible for a domain, or other information about a domain. There are several types of DNS records, including − A records − A records map a domain name to an IP address. CNAME records − CNAME records allow you to specify an alias for a domain name. MX records − MX records specify the mail server responsible for a domain. NS records − NS records specify the name servers for a domain. TXT records − TXT ... Read More
Overview The Internet Corporation for Assigned Names and Numbers (ICANN) is an international organization that plays a vital role in the functioning of the Internet. It is responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, including domain names and IP addresses. In this article, we will take a closer look at what ICANN is, what it does, and how it impacts the daily use of the Internet. Internet First, it is important to understand the basic structure of the Internet. At its most basic level, the Internet is ... Read More
The DNS name space is the set of all domain names that are registered in the DNS. These domain names are organized into a tree-like structure, with the top of the tree being the root domain. Below the root domain, there are a number of top-level domains, such as .com, .net, and .org. Below the top-level domains, there are second-level domains, and so on. Each domain name in the DNS name space corresponds to a set of resource records, which contain information about that domain name, such as its IP address, mail servers, and other information. The DNS name space ... Read More
The Bundle Protocol is a networking protocol used to transmit data between nodes in a delay-tolerant network. A delay-tolerant network is a type of network that can operate in environments where there is a significant delay or interruption in the flow of data. The Bundle Protocol is designed to provide reliable end-to-end communication in these types of environments, where other networking protocols may not be effective. The Bundle Protocol is used by several space communications systems, including the Delay/Disruption Tolerant Networking (DTN) system developed by NASA. It is also used in other applications where traditional networking protocols may not be ... Read More
Network performance refers to the quality and speed of a network's transmission of data between devices. It is typically measured by factors such as bandwidth, latency, and throughput. Network performance is important because it determines how well devices can communicate with each other and access the resources they need, such as the internet or shared files. Poor network performance can lead to slow response times, reduced productivity, and other problems. Five Common Potential Issues that can Affect Network Performance Bandwidth bottlenecks − If the network's available bandwidth is inadequate for the number and type of devices and applications using ...

Minutes and seconds are more basic units for measuring rotation than degrees. Using minutes when measuring rotation helps us analyse the values more accurately and efficiently. We can convert decimal degrees into degrees, minutes, and seconds using the VBA application, as it can’t be completed directly in Excel. This tutorial will help you understand how we can convert decimal degrees to degrees, minutes, and seconds in Excel. Here we will demonstrate two methods for converting decimal degrees to degrees, minutes, and seconds and degrees, minutes, and seconds to decimal degrees. Convert Decimal Degrees to Degrees Minutes Seconds Here, we will ... Read More
You might occasionally have needed to convert a decimal number in Excel into another format, such as binary, octal, or hexadecimal. In general, decimal numbers have a base of 10 from 0 to 9, binary numbers have a base of 2 from 0 to 1, octal numbers have a base of 8 from 0 to 7, and hexadecimal numbers have a base of 16 from 0 to 9 and A to F. You may learn how to convert decimal numbers in Excel to binary, octal, and hexadecimal by reading this article. Convert Decimal Number to Binary Number in Excel Here, ... Read More
