What is a network?

Ismael Sixon: Network: general translated into English: internet, network or [Electrics] [Computer] a network. Simple, it is the physical link with the various isolated workstation or host connected together to form the data link, thereby achieve the sharing of resources and communication purposes. Where different geographic location and function of the number of independent computer systems through which communications equipment and lines to link up and to improve the function of the network software (Internet protocol, information exchange and network operating systems, etc.) to achieve the shared network resources System, known as the computer network.Jack...Show more

Somer Distilo: A packet sniffer is a program (that runs on network hardware) that has the ability to "read" or "sniff" all the network traffic (packets) on a certain network that may provide specific information; a packet sniffer dumps all this network traffic for a person to analyze and look for pa! tterns and behaviors on specific applications (i.e. ssh, HTTP, telnet, smtp, etc. etc.) or to analyze possible hacking attempts.One of the most used is snort, nmap and some others.If you want to try one out you may one to use a forensic Linux Bootable CD; they've always come with one or two.regards

Emile Midgley: A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building.Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers (and their human users) on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) for the network's resources, and many others.Workstations are called such be! cause they typically do have a human user which interacts with! the network through them. Workstations were traditionally considered a desktop, consisting of a computer, keyboard, display, and mouse, or a laptop, with with integrated keyboard, display, and touchpad. With the advent of the tablet computer, and the touch screen devices such as iPad and iPhone, our definition of workstation is quickly evolving to include those devices, because of their ability to interact with the network and utilize network services....Show more

Vern Serratos: Two or more workstations or servers attached together by electronical means. They are able to communicate over different protocals like TCP/IP. A network usually has a switch or a router to direct the traffic to the correct place.

Dorinda Metzer: (also known as a network analyzer or protocol analyzer or, for particular types of networks, an Ethernet sniffer or wireless sniffer) is computer software or computer hardware that can intercept and log traffic passing ! over a digital network or part of a network.[1] As data streams flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.Meaning if your using a lan that has a packet sniffer, they can capture the information you type into websites...ex. passwords and what not.

Ty Kirton: A packet analyzer (additionally universal as a community analyzer, protocol analyzer or sniffer, or for particular varieties of networks, an Ethernet sniffer or prompt sniffer) is laptop utility or laptop hardware that would intercept and log site visitors passing over a digital community or area of a community.[a million] As documents streams bypass around the community, the sniffer captures each and each packet and at last decodes and analyzes its content cloth in accordance to the suited RFC or different specs.

Claire Billegas: You shouldn't of dropped out of school.

Sammy Kar: In ! the world of computers, networking is the practice of linking two or mo! re computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks.The most common topology or general configurations of networks include the bus, star, Token Ring, and mesh topologies. Networks can also be characterized in terms of spatial distance as local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs).A given network can also be characterized by the type of data transmission technology in use on it (for example, a TCP/IP or Systems Network Architecture network); by whether it carries voice, data, or both kinds of signals; by who can use the network (public or private); by the usual nature of its connections (dial-up or switched, dedicated or nonswitched, or virtual connections); and by the ! types of physical links (for example, optical fiber, coaxial cable, and Unshielded Twisted Pair). Large telephone networks and networks using their infrastructure (such as the Internet) have sharing and exchange arrangements with other companies so that larger networks are created....Show more

Tosha Tawney: why we refresh the comuters?

Tillie Wynott: when more than one computer are connected to a server computer or each other that is called networking,Two or more computers linked together physically or via telecommunications for the purpose of electronically sharing resources such as computer files, programs, peripheral devices, and either centralized or distributed services.

Betsey Copp: Communication

Ronny Nowzari: When you have two or more computers connected to each other, you have a network. The purpose of a network is to enable the sharing of files and information between multiple systems. The Internet could be described as a global network o! f networks. Computer networks can be connected through cables, such as ! Ethernet cables or phone lines, or wireless, using wireless networking cards that send and receive data through the air.

A group of two or more computer systems linked together in order to share information and resources. There are two main categories of computer networks: LAN and WAN. Two or more computers linked together physically or via telecommunications for the purpose of electronically sharing resources such as computer files, programs, peripheral devices, and eith! er centralized or distributed services. Connec! tion between two or more computers which allows them to share the same software and information. A hardware and software data communication system. Usually a group of computers that are linked to share memory and programs....Show more

Claire Billegas: Network is some PC Interconnection who send data from one pc to another pc

Jeannetta Gaffigan: A friend showed me one in action. Its just damn scary what it can do.

Nilda Bafia: a). The "apropos" command (or "man -k") finds appropriate man pages based on a keyword match. Individual pages are searchable by whatever mechanism your pager provides. Less is usually the default which allows searching by pressing "/".

Jarrod Darnall: A hacker's friend; it analyzes the network traffic going past it even though the traffic is not meant for it.

Brice Greczkowski: As Per wikipedia it is a group or system of interconnected people or things.

Branden Round: Refresh means to rew! rite, update, reload, or anything like that. The refresh rate on your monitor is how many times per second the screen is updated or redrawn. Vertical refresh is how many times per second the screen is drawn from top to bottom. Horizontal refresh is how many times a row can be drawn from left to right, usually tens of thousand of times per second.Dynamic RAM (all RAM outside the processor and its cache) has to have the data stored in it refreshed or rewritten in order for the data to stay there.
