The Ultimate Guide to Mastering Ping in C Programming: Basics, Commands, and Troubleshooting
In C programming, implementing a ping utility involves creating ICMP (Internet Control Message Protocol) echo request packets and analyzing the responses. Ping is a fundamental network diagnostic tool that helps test connectivity, measure latency, and troubleshoot network issues. Syntax #include #include #include int socket(int domain, int type, int protocol); int sendto(int sockfd, const void *buf, size_t len, int flags, const struct sockaddr *dest_addr, socklen_t addrlen); How Ping Works Ping operates by sending ICMP echo request packets to a ...

Read MoreNear Field Communication
Introduction to Near Field Communication (NFC) Near Field Communication (NFC) may be a short-range remote communication technology that permits two electronic gadgets to set up communication when they are set in the near vicinity, ordinarily inside some centimeters. NFC is an expansion of Radio Recurrence Distinguishing Proof (RFID) innovation and works at a recurrence of 13.56 MHz. NFC innovation empowers contactless communication and information trade between gadgets, making it helpful and proficient for different applications. Working of NFC The essential rule behind NFC is using electromagnetic areas for information exchange. It utilizes inductive coupling, where the NFC-enabled gadgets create attractive ...
Read MoreEthernet Frame Format
Ethernet is a widely used local area networking technology that enables devices to communicate with each other. Ethernet frames are basic units of data that are transmitted over Ethernet network. In this article, we will explore Ethernet frame format in detail, including various fields that make up frame and purpose of each field. Introduction to Ethernet Frames An Ethernet frame is a packet of data that is transmitted over an Ethernet network. frame is composed of a header, a payload, and a trailer. header and trailer contain information about frame, such as source and destination addresses, while payload contains actual ...
Read MoreDifference Between EBCDIC and ASCII
EBCDIC (Extended Binary Coded Decimal Interchange Code) and ASCII (American Standard Code for Information Interchange) are two-character encoding methods used in digital communication to represent characters. ASCII is a character encoding method that uses a 7-bit code to represent 128 characters, which include letters, numbers, and special characters. EBCDIC has 256 characters and is used to represent a wide variety of characters, such as letters, numbers, special characters, and control characters. Read this article to find out more about EBCDIC and ASCII and how they are different from each other. What is EBCDIC? IBM created EBCDIC (Extended Binary Coded ...
Read MoreMultilevel Feedback Queue Scheduling (MLFQ) CPU Scheduling
Introduction MLFQ Programming is an instance of CPU scheduling technique that works through preserving several queues based on priority, each with a distinct time quantum. The delay period of those with greater importance queues is shorter, whereas the duration period of the ones with lower importance holds is longer. When a fresh procedure emerges, it is assigned to the top of the importance queue. The timer for the CPU chooses the most significant operation from the most important queue and allocates the processing power to it. The procedure is permitted to continue for a set amount of time or ...
Read MoreMethods in Interprocess Communication
Introduction Inter process communication (IPC) was the transfer of information and interaction between multiple processes in an electronic system. Every operation in a tasking process structure runs on its own, as well as communication between them is required if these processes require to exchange of information or coordination of what they are doing IPC is an essential part of contemporary operating systems and can be employed in a variety of applications, which include simple control-line appliances to complicated systems with distributed components. The primary goal of IPC is to make the transmission of knowledge among processes more private and effective. ...
Read MoreMessage-based Communication in IPC(inter-process communication)
Introduction Message-based communication (MBC) is a type of communication within a process (IPC) in which multiple procedures share data by sending statements to the other person. The transmission procedure structures an e-mail that included what needs to be passed on and provides it to the process of reception in this form of interpersonal interaction. In turn, the procedure for receiving gets the communication and herbal extracts whatever data is required. Utilizing memo-based interactions in IPC has multiple benefits. One of the primary benefits is that it offers a simple and adaptable way to facilitate interaction between procedures. Asynchronous programming message ...
Read MoreDifference between encapsulation and decapsulation
Whenever we share data and information, it is very important to make sure the data reaches its destination; it is not lost somewhere through its path during transmission. If the communication is secure, then the time consumed will also be less. But before proceeding we must know that data encapsulation and decapsulation help in working and processing the data transmission. It provides reliability and security to the data that is being transferred from the sender to the receiver so that no unwanted access can happen. It also helps in hiding the complex details of the transmission system so that no ...
