This book puts the most easily tested basic test points for domestic companies in Part 2 C ++ BASIC program design, hoping to effectively solve practical interview problems.PrivateThe interview questions examine the ability of a specific category through a single question.

, Linmodem is usually of the PCI type. You can obtain the device description through the PCI detection process. After obtaining the description, you can compare whether your Modem belongs to the Modem type listed below. Currently, the following Linmodem types are supported: * Conexant/Rockwell HSF Its driver is at http://www.olitec.com/pci56kv2.htmlor http://linmodems.org. * Ambient Technology (formerly Cirrus Logic) The driver is available at http://linmodems.org/clmodem-0.3.0.tar.gz. * Lucent

Linux supports NICs through the kernel. In the early days, many people directly add Nic support during compilation. However, with the increase of NIC types, few have used this thankless method. Currently, most people use the NIC module to drive the NIC. In order to join the network card, you must first know the network card type. in Linux, the support for the broken "NE 2000 compatible" network card is indeed good, but it is not easy to say about a MB Nic. You can always select a suitable produc

communication packets to the entire switching network, the switch is misunderstood as a broadcast storm. In short, direct forwarding applies to network environments with good network link quality and fewer error packets. Storage forwarding technology: (store-and-forward) The storage and forwarding technology requires the switch to decide how to forward after receiving all data packets. In this way, the switch can check the integrity and correctness of data packets before forwarding. The advanta

Other implementations and versions4 references5 external links [Edit] HistorySMB was initially developed by IBM Barry Feigenbaum to transform the local file interface "interrupt 13" in the DOS operating system into a network file system. Later, Microsoft made major changes to this development. The changed version is also the most common version. Microsoft integrated the SMB protocol with the network management program developed together with

An Ethernet NIC consists of two layers of the OSI (open-party system interconnection) model. Physical Layer and data link layer. The physical layer defines the electrical and optical signals, line statuses, clock baselines, data encoding, and circuits required for data transmission and receiving, and provides standard interfaces to data link layer devices. The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces

connections to multiple subnets in the same way. The biggest function of a VLAN is to prevent broadcast storms. Generally, if a broadcast packet occupies more than 30% of all communication packets, the network performance will be significantly reduced. Currently, almost all vswitches provide VLAN support. Although it is a little difficult to set a VLAN, it is recommended that the network management can configure a VLAN because of its significant performance improvement. Setting computers with h

In addition, you can modify the source MAC address of the actually sent Ethernet packet through the operating system. Since the MAC address can be modified, the binding between the MAC address and the IP address will lose its original meaning. 2.2 cracking Solution Is the structure of the cracking test. Both the internal server and external server provide Web Services, and the firewall binds the MAC

In fact, Cisco does not take a special advantage in the low-end switch market, because 3Com, Dlink and other companies have better performance and price ratios. The 1900 vswitch is a typical low-end product for desktop computer access at the end of the network. It provides 1

Branch switches.The cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the port directly connected to the vswitch, you can allocate and configure VLANs across the entire network.The core switch is configured as follows:Com (config) # in
