The network adapter is also known as the NIC or network interface card (NIC), the English name network Interface card. It is a device that enables computers to be networked. The NIC is the network adapter that connects the PC to the LAN. The NIC is plugged into the computer's motherboard slot, It is responsible for tra

To improve network management efficiency, it is necessary for us to generate a convenient and intuitive network topology map for our local area network in a timely manner. This network topology map is cleverly used, we can quickly find the source of network faults. Now, I wi

1 Introduction to VMware Three network modesVMware offers three modes of operation, which are bridged (bridging mode), NAT (network address translation mode), and host-only (host mode). after installing the virtual machine, you can see more than two NICs in the network connection. Such as. 2 bridged (bridging mode) 2.1 mode introduction in this mode, VMware virtu

Network devices (routers, switches, firewalls, and so on) require an operating system as well as computers. Network devices use a dedicated operating system, collectively known as iOS (Internetwork Operating system, network operating system).(1) Common connection mode of network equipment:There are four common ways to

Fourth Chapter Network layer 1. Two services at the network layer : Virtual circuit Service (reliability guaranteed by the network) and datagram service (reliability guaranteed by the user host)2. Internet Protocol(1) Address Resolution Protocol ARP and Inverse Address Resolution Protocol (RARP): Under IP protocol, IP uses these two protocols to resolve to th

NAT (Network address translation) is the process of converting an IP address in an IP packet header to another IP address. In practical application, NAT is mainly used to realize the function of private network accessing public network. This way, by using a small number of public IP addresses to represent more private IP addresses, will help to slow the depletion

How to differentiate between dual-screen and unshielded Network cables and dual-screen network cable shielding As a part of the Integrated Wiring Design and Construction, the network cable is the basic medium for most information transmission systems. Its importance is self-evident. What is the main role of this article in resolving and shielding the

When you cannot connect to the Internet, there are times when you need to do some experimentation to require that the host system and the virtual system interconnect. At this point, you can solve the demand by configuring the loopback network card. This article describes a brief step, starting with the Internet. First of all, the reason for this is to evade the research on VMware Network settings. When our

2018.9.1 Network security day01_ computer network and stratification thought Layered thought of network security computer NetworkLAN and WAN LAN (local area network)-Lan A local areanetwork, or LAN, is a group of computers interconnected by multiple computers within a region. "One area" means the same office, th

We know that vmware workstation provides many virtual devices. By using these devices, we can build a typical bridging network, host-only network, and Nat network, you can also build complex custom networks. This article aims to let everyone know and master the various network devices of VMware Workstation Virtual, and
