Network Topology and Wiring Tiearia Fariss NTC/361 Professor: Larry Schreider December Network Topologies are the different arrangements that contain many different element such as links‚ nodes‚ etc. This helps with communication and network information processing. This is a major part of today’s technology and is used by big business as well as for home and personal use. There have been eight different network topologies that have been recognized though out a study.. Throughout this paper

COMPUTER NETWORK ADMINISTRATOR A computer network (the "network") is the connection of at least two or more computers for the purpose of sharing data and resources. These resources can include printers‚ Internet access‚ file sharing‚ and electronic mail ("e-mail"). In today ’s technological environment‚ most companies and businesses have some kind of network used on a daily basis. Thus‚ it is imperative to day-to-day operations that networks run smoothly. Companies employ at least one person

Wireless network refers to any type of computer network that uses wireless (usually‚ but not always radio waves) for network connections. It is a method by which homes‚ telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building‚ or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place

Network Attached Storage In this paper‚ I will be specifically covering what a NAS device is‚ what the speed of the network adapter for a NAS device would be‚ what kind of capacity range the NAS has‚ if it has any fault tolerances‚ if management features are available‚ and why a user would like to use a NAS. A NAS or “Network Attached Storage” is a a device with hard disk storage setup on a network; with its own network address‚ rather than being attached to a computer‚ it serves the applications

Abstract Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure‚ a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow‚ released in the year 2008‚ is a commercially viable implementation of this
