PHIL 80: MIND, MATTER AND MEANING Paper 1 – Final Version Prompt 2: A crucial thought behind Van Inwagen’s Consequence Argument is that we lack the ability either to change the past or change the laws. If determinism is true, he argues, our present actions are a direct

LAN A local area network, or LAN, is a group of nodes that covers a small area, usually a single building or group of buildings (Advameg, 2014). Any time two or more digital devices communicate locally, not over the internet, it is a LAN. A LAN can be as small an ad hoc network between two cell phones, or it could be thousands of nodes in an office building. These nodes could be digital devices like PCs, printers, server, and mobile devices. The purpose of a LAN is to allow digital devices to communicate

COMMUNICATION TECHNOLOGY TASK 1 TOPOLOGIES WAN AND LAN WAN (WIDE AREA NETWORK) WAN is also known as wide area network, it covers a large region or country. A wan consist of two or more local area network. Computer are connected to a modem and the rooter is then connected to a telephone connection which is the PSN (PUBLIC SWITCH NETWORK). LAN (LOCAL AREA NETWORK) LAN (local area network) allows a computer to connect to a network to gain access to internet

area. They currently have three locations: the home office in La Jolla, CA., and two store locations in Del Mar, CA. and Encinitas, CA. Kudler is in need of a new network design and topology that will address multiple issues faced in a growing enterprise. The new network must incorporate a new network topology to reduce downtime and ensure that functionality will remain if one or two devices are down. In addition, a VoIP system must be installed over the network, along with an internal WLAN in

Another must-have will include security measures for the executive level of management via access authentication for all devices, data encryption for all files and media functionalities for the communication needs of the business. Certain limitations may include environmental cabling blockage or RF broadcast failure if a wireless network is used. The office

developed. Next in 1982 the word “internet” was coined. Then in 1983 the computer industry called that year “the year of the LAN”, because it was deemed that was the breakout year for the industry. Next we can jump to 1990 when Tim Berners-Lee creates the World Wide Web. Then in the 1990s dial-up internet became affordable for home use, and this is where we see a giant leap in LAN

the performance can be slower than other networks topologies. And if one device is off or if the cable breaks, the entire network fails. Describe Token Passing. Token passing: It is channel access method in which a signal called a token (a series of bits) is passed between 2 nodes that grants permission to the nodes to communicate. When its function is finished the device passes the token along to the next device in the topology. In the protocol there are system rules that manage

transmission on the network. The Ethernet protocol allows for linear bus, star, or tree topologies. Data can be transmitted over twisted pair, coaxial, or fiber optic cable at a speed of 10 Mbps. Ethernet is a physical and data link layer technology for local area networks (LANs). Ethernet was invented by engineer Robert Metcalfe. It uses wires (meaning it is not a wireless technology). The wires used for a LAN are mostly those headed by an RJ-45 jack, which is similar to the jack plugged into your
