configuration, and supported standards. Specifically explain the VLAN concept and its use within the wired LAN infrastructure. What healthcare use can you envision for wired LAN? If unsure, search the literature for answers. A wired LAN connects computers within an organization in a network configuration and each PC on the LAN must connect to the network with a network interface card (NIC). The NIC needed varies by which cabling is used for the network (Cowley, 2012). NICs help to direct traffic on the network if a shared medium is used and they also help detect transmission errors (Cowley, 2012). Wired LANs can be complex and expensive to configure in an institution; some equipment needed for a wired LAN include hubs, switches, and routers. The hub, which is an OSI Level 1 device, acts as a signal booster within the LAN. Switches are OSI Level 2 devices and are actually intelligent devices that understand the addresses, connect different LAN segments, increase the bandwidth on the LAN, and are needed to create virtual LANs (VLANs) (Cowley, 2012; Morency, 1995). The wired LAN needs a dedicated location in a closet to house the patch panel/switchboard that connects all the wires from all the PCs on the network as well as the server. The equipment…

Networking P1: DESCRIBE THE TYPES OF NETWORKS AVAILABLE AND HOW THEY RELATE TO PARTICULAR NETWORK STANDARDS AND PROTOCOLS There are many types of wireless networks available. This includes: WAN, LAN, MAN, PAN, WLAN. Below, I will go into detail about each type that will help you understand exactly what each type of network is and what it consists of. What is WAN? WAN or also known as a Wide Area Network is a network that consists of many Networks that are a part of other LAN networks that swaps…

The Key Concepts of Network Configuration Network configuration starts with a device such as a computer, each device requires the assignment a unique number to identify it on the network, known as an IP address which stands for Internet Protocol Address. Every device requires an IP address from a cell phone to a fax machine. This number gives your device the ability to communicate with other devices and available networks. Once the original device requires network access to another device,…

Introduction This paper describes seven threats to a network belonging to a fictitious marketing company in Kansas City, Missouri. These threats are based on different IT infrastructure domains. The detail of these threats explains the possible outcomes and endeavors to point out “what is the worst that can happen” from that threat. Threats The first threat area is the user domain. The user domain consists of the actual users, or people, in the company, including subcontractors, vendors, and…

1. Ethernet Ethernet is a combination of computer networking technologies most commonly used in local, metropolitan, and wide area networks. 2. Server A computer or computer program that manages access and distributes information through a centralized service in a network. 3. IP Transit IP Transit, also known as Internet Transit, is what allows traffic from a network to cross or "transit" to a provider network.

Network hardware is the physical equipment that is required to allow devices to transmit data to another device. The devices have the ability to transfer over many types of media, but there are only two basic types of transmission. We first have the broadcast transmission which transfers the same messages to multiple recipients. Then there is point-to-point links that establishes a connection between two individual 's devices for data transmission. Networks rely on these two types of…
