In a network, what is the fundamental building block that allows multiple devices to communicate with each other?

A process can be of two types: • Independent process. • Co-operating process. An independent process is not affected by the execution of other processes while a co-operating process can be affected by other executing processes. Though one can think that those processes, which are running independently, will execute very efficiently, in reality, there are many situations when co-operative nature can be utilized for increasing computational speed, convenience, and modularity. Inter-process communication (IPC) is a mechanism that allows processes to communicate with each other and synchronize their actions. The communication between these processes can be seen as a method of co-operation between them. Processes can communicate with each other through both: An operating system can implement both methods of communication. First, we will discuss the shared memory methods of communication and then message passing. Communication between processes using shared memory requires processes to share some variable, and it completely depends on how the programmer will implement it. One way of communication using shared memory can be imagined like this: Suppose process1 and process2 are executing simultaneously, and they share some resources or use some information from another process. Process1 generates information about certain computations or resources being used and keeps it as a record in shared memory. When process2 needs to use the shared information, it will check in the record st...

Virtual Networking enables the communication between multiple computers, Virtual networking enables devices across many locations to function with the same capabilities as a traditional physical network. This allows for data centers to stretch across different physical locations and gives network administrators new and more efficient options, like the ability to easily modify the network as needs change, without having to switch out or buy more hardware; greater flexibility in provisioning the network to specific needs and applications; and the capacity to move workloads across the A virtual network connects virtual machines and devices, no matter their location, using software. In a physical network, layer 2 and 3 functions of the OSI model happen within physical switches and routers. Plus, physical network interface cards (NIC) and network adapters are used to connect computers and servers to the network. Virtual networking shifts these and other activities to software. A software application, called a virtual switch or vSwitch, controls and directs communication between the existing physical network and virtual parts of the network, like virtual machines. And a virtual network adapter allows computers and VMs to connect to a network, including making it possible for all the machines on a local area network (LAN) to connect to a larger network. In a physical network, LANs are created to connect multiple devices to shared resources, like network storage, usually through E...

Network hardware is defined as a set of physical or network devices that are essential for interaction and communication between hardware units operational on a computer network. This article looks at the fundamentals of network hardware, network architecture and its key components, challenges of network hardware, and the top 10 best practices for efficient network hardware management for 2022. Table of Contents • • • • Network hardware is a set of physical or network devices that are essential for interaction and communication between hardware units operational on a computer network. These are dedicated hardware components that connect to each other and enable a network to function effectively and efficiently. Today, technology has penetrated its tentacles into every nook and corner of our lives. It has gone from being just an industry add-on to an inevitable necessity. As tech enablement is driving the industrial transformation, it’s important for businesses to build a network that is secure, reliable and keeps the users in touch with their applications. The core of this very foundation is leveraged by the basic network hardware. Network hardware plays a key role as industries grow as it supports scalability. It integrates any number of components depending on the enterprise’s needs. Network hardware helps establish an effective mode of communication, thereby improving the business standards. It also promotes multiprocessing and enables sharing of resources, information,...

Published on April 7, 2022 Routers, switches, and firewalls are three core components of any network. Once you have an understanding of them, everything else is a little easier to understand. As the world becomes increasingly remote, the demand for network professionals is skyrocketing. When it comes to networking, there is no better way to level up your skills than to earn a Like most What is a Network Switch? A switch is a device that allows us to connect multiple computers together. While computers are the main device hooked into switches, it can also connect printers, security cameras, Cisco Voice IP phones, and more. Once a switch is connected to a device, the MAC (Media Access Card) address of the device is discovered and used for routing. The switch attaches the MAC to outgoing packets so the device can be identified by other devices on the network. This is considered Layer 2 (L2) communication in accordance with the A network switch provides full-duplex communications. This means that network packets are sent back and forth without having to wait for a response. In fact, all three components mentioned today are full-duplex. Some switches are considered managed, while others are unmanaged. Unmanaged vs. Managed Switches An unmanaged switch is considered plug-and-play. In other words, the switch arrives pre-configured out-of-the-box, and there isn't a whole lot you can do with it. Unmanaged switches are the sort of devices that are seen in private homes or small offi...

Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies. Let’s answer some common computer networking FAQs. Nodes and links are the basic building blocks in computer networking. A network node may be data communication equipment (DCE) such as a modem, hub or, switch, or data terminal equipment (DTE) such as two or more computers and printers. A link refers to the transmission media connecting two nodes. Links may be physical, like cable wires or optical fibers, or free space used by wireless networks. In a working computer network, nodes follow a set of rules or protocols that define how to send and receive electronic data via the links. The computer network architecture defines the design of these physical and logical components. It provides the specifications for the network’s physical components, functional organization, protocols, and procedures. Computer networks were first created in the late 1950s for use in the military and defense. They were initially used to transmit data over telephone lines and had limited commercial and scientific applications. With the advent of internet technologies, a computer network has become indispensable for enterprises. Modern-day network solutions deliver more than connectivity. They are critical for the digital transformation ...
