Computer Network A computer network is a group of computers that are interconnected by electronic circuits or wireless transmissions of various designs and technologies for the purpose of exchanging data or communicating information between them or their users. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of types and categories and also presents the basic components of a network. Introduction A computer network allows sharing

An adjustment of the antennas may be necessary. An internetworking device that seamlessly connects wired and wireless networks. Access A device that provides wireless points combined with a Access Point (AP) clients with access to a wired distributed system support the network. creation of multiple radio cells that enable roaming throughout a

where users first connect to the IT infrastructure. Because of numerous threats, it is necessary to implement a workstation logon for the user to authenticate the user for the security control of this domain. Users will be authenticated in the system by defining its credentials and roles to the system in order to gain permission and access to the IT infrastructure (Tipton and Henry, 2007). LAN Domain This is the domain where all the computers, printers, and servers connect to each other

Case Project 1-2 To accommodate a small network, not much equipment is required. A switch and enough Cat5 cable to connect each Workstation should do the trick. Since there are only 6 Workstation’s on this network it will take very little time to setup each one and train the employees on how to share resources. I would create power user accounts on each Workstation and join them to the same Workgroup and activate print and file share services. I would show each employee how to login to their

offer a variety of connection speeds. The two most commonly used networks are client servers and peer to peer (P2P) networks. There are many ways that computers connect and share information with each other. Computers today connect and share information by connecting to a network. There are several types of networks that computers can connect to, but the two most popular are local area networks (LAN) and wireless local area networks (WLAN). In a computer network, anything that a computer can communicate

IT, Web Routing Name: Institution: Routing A router is a network device capable of passing data between two networks. The most basic reason for using a router is to connect a LAN to the internet (Lowe, 2013). A bridge on the other hand sits between two types of networks, for example between an Ethernet and wireless (Pomerleau, 2009) Routers can be helpful under the following circumstances. To begin with, routers are capable of connecting different network architectures such as Ethernet and

Attacks that once required attackers to have an advanced degree in computing now can be done with easily downloaded and freely available tools that the average junior-high student can figure out how to use. Every company and almost every person connects to the Internet, making essentially the whole world vulnerable to attack. The biggest danger today may be the changes in attacker’s motivation. Instead of looking for a challenge, or to steal millions, today’s attackers can be much more organized

equipment that can switch calls locally or to long-distance carrier phone offices. c. Local Exchanges Local Exchange (LEC) is the term for a public telephone company in the U.S. that provides local service. LEC are also known as “telcos,” which connect to other LEC’s within a local access and transport area (LATA) or to interexchange carriers (IXCs) such as long-distance carriers. d. POP Point-Of-Presence (POP) is an access point form one place to the rest of the Internet. It has a unique internet

will explain later and a range of different components. Such as, Bridge, Router, DSL modem, Switch, Network interface card also known as NIC and finally the Hub. Firstly, I am going to briefly explain what a bridge is. A bridge is a component that connects a local area network also known as LAN, to another local area network using the same protocol such as the Ethernet or even a token ring. The bridge is a device that determines if a message is required to transmit or not. A bridge identifies each
