 Wired And Wireless LAN 1.  Answer the following questions in short. 1. What is IEEE standards?      Answer:             The Institute for Electrical and Electronic Engineering developed an Ethernet standard know as IEEE standard 802.3. Ethernet is the most widely-installed Local Area Network technology.            This standard defines rules for configuring an Ethernet network and also specifies how the elements in an Ethernet network interacts with one another. By following IEEE standard, network equipment and network protocol can communicate efficiently. 2. Describe Fast Ethernet.      Answer:              The Fast Ethernet standard (IEEE 802.3u) has been established for Ethernet networks that need higher transmission speeds. This standard raises the Ethernet speed limit from 10 mbps to 100 mbps with only minimal changes to the existing cable structure. Fast Ethernet provides faster throughput for video, multimedia, graphics, Internet surfing and stronger error detection and correct

 Network Connectivity Devices 1.  Answer the following questions in short. 1. What are network connectivity devices?      Answer:            Network Connecting devices includes all computers, peripherals, interface cards and other equipments needed to perform data-processing and communications within the network.          Example: Network Interface Card(NIC), Hub, Switch, Bridge, Router, Gateway. 2. What is active and passive hub?      Answer:            Active hub is a type of hub that takes active participation in data communication within the network/LAN. An active hub is basically a multiport repeater of the class II type, although it is still a physical layer device - it buffers incoming frames and regenerates them, sending the regenerated signal out on all of its ports.          Passive hubs does not provide any additional features except for working just as an interface between the topology. A passive hub simply receives signals on input port and broadcast it on the output port

Network Security  1.  Answer the following questions in short. 1. What is meant by Network security?      Answer:             Network / Computer security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources.          Network security involves the authorization of access to data in a network, which is controlled by the network administrator. 2. What is plaintext and ciphertext?      Answer:           The plaintext or clear text message can be understood by anybody, (sender, recipients) else who gets access total message.         When a plaintext message is codified using any suitable scheme (encryption), the resulting message is called ciphertext .          The message to be encrypted, know as "plain text"          The output of the encryption process, known as the "ciphertext" 3. What is attack? What are its type?

 Network Models Question And Answer 1.  Answer the following questions in short. 1. what is network model?      Answer:            A Network Model reflects a design or architecture to accomplish communication between different systems. Network models are also referred to as network stacks or protocol suites. Examples of network models includes  TCP/IP, Sequenced Packet Exchange/Internet Packet Exchange(SPX/IPX) used by Novell Netware, the Network Basic Input Output System (Net-BIOS), which comprises the building blocks for most Microsoft networking and network applications; and AppleTalk, the network model for Apple Macintosh computers.     A network model usually consists of layers. Each layers of a model represents specific functionality. Within the layers of model, there are usually protocols specified to implement specific tasks. 2. Write name of addresses used in TCP/IP protocol.      Answer:       In TCP/IP, different levels of addresses are used, Physical Address(Hardware Addres

Introduction To Computer Network  1.  Answer the following questions in short. 1. Define Computer Network.     Answer:        A computer network is a system for communication among two or more computers. They are linked together through either a physical cable,  or a wireless device. This link then allows the computers on the network to share resources such as an Internet connection, printers, files, and programs. 2. How are networks classified?     Answer:        Computer networks fall into three classes regarding the size, distance  and the structure namely LAN (Local Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network) 3. State applications of computer network.     Answer:        A computer network has following applications: Resource Sharing: Information Sharing: Person-to-person Communication: Electronic Business: Interactive Environment: Manufacturing: Marketing and Sales: Banking: Financial services: Insurance: 4. Enlist various advantages and disadvantages of
