Recently opened the route for a new internet café, the Internet Café administrators ran to ask me, Internet cafes in the computer interconnection of the selected cable (hub) Good or switch good, Cisco's switch is not the best. People often say that only the right choice is not expensive. But how is the right choice? The common medium and small-sized network has two hundred or three hundred computers, many people reach thousands of units. They are conn

Management and maintenance of the local area network is a very annoying thing, because the network administrator will often face such a problem, that is, set up their own LAN parameters, was modified by other people, resulting in the network can not connect normally, after the failure, they must also be a failure of the computer to be carefully excluded, Until t

Network application is the reason why computer networks exist. If we don't envision any useful Web applications, then there's no need to design a network protocol that supports them. However, in the past 30 years, many people have devised a large number of sophisticated Web applications. These applications include text-based classic applications that have been popular since the the 1980s, such as remote com

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

reality is that the service quality is still far away from the real support for multi-service broadband applications. QoS alone cannot completely solve the problems it needs to solve. Users need to continuously improve their bandwidth, and require a variety of network applications to operate on a simple platform. The network structure is simplified but the maximum controllability is required, the current

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

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
