What Is a Network A network is a tool that enables two or more parties to connect with each other. Without networks, the "standalone" computing world would be quite isolated. Purpose of Using a Network The primary goal is to connect multiple parties for communication, transferring data from one side to another. Programs written ...

Socket communication relies on a well-defined handshake process for establishing and terminating connections. Connection Handshake (Three-Way Handshake) Client sends a connection request. Server acknowledges the request. Client confirms the connection. After these steps, data can be exchanged using Send and Receive. Disconnection Handshake (F ...

To assign a static IP address to a Docker container on CentOS 7 using pipework, begin by setting up a Linux bridge. First, modify the physical interface configuration to attach it to a bridge. Edit /etc/sysconfig/network-scripts/ifcfg-ens33: TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFR ...

Core Internet Concepts The internet functions as a network of networks, serving as the parent set for all network types. The Internet represents the world's largest internetwork—a specific implementation within the broader internet concept. Computers connected to the Internet are commonly referred to as hosts. The World Wide Web (WWW) is not a ...

Connection Issue Analysis When attempting to push code to GitHub on Windows systems, developers may encounter the error: Failed to connect to github.com port 443: Timed out. This prevents both Git operations and web access to GitHub services. Troubleshooting Approach The initial assumption might be proxy configuration issues. After disabling pr ...

Computer systems store signed integers using two's complement representation. Sign-magnitude and one's complement forms are only conceptual steps used to derive two's complement; they are not stored in memory. Sign-Magnitude Representation A positive integer's sign-magnitude representation is identical to its binary form. Example for a single- ...

Samba is a free open-source implementation of the SMB (Server Message Block) networking protocol for Linux and Unix systems, consisting of both server and client components. SMB is a client-server based communication protocol that enables sharing of files, printers and other resources across nodes on a local area network. By enabling NetBIOS ov ...

TCP Overview The Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol operating at the transport layer. Defined by IETF's RFC 793, TCP ensures data integrity through sequencing, acknowledgment, and retransmission mechanisms. Communication using TCP requires three stages: establishing a connection, transferring data, a ...

Overview This guide demonstrates three methods for connecting container networks across different nodes using Linux iproute2 tools. These approaches replicate the backend capabilities commonly used in container orchestration platforms. The three methods covered include: host-gw (host gateway mode) ipip (IP-in-IP tunneling) vxlan (Virtual Exten ...

After installing a KVM virtual machine using virt-install, it often comes with only a single network interface. To add additional interfaces, the virsh attach-interface command can be used. Initially, the VM may appear as follows: $ virsh domiflist ubuntu1604-test-vm1 Interface Type Source Model MAC ---------------------------- ...
