In this report I will be outlining the features and functions of any interconnection devices that you might think of using. In the report I will include Network Interface Card, Router, Switch, Hubs, Gateway, Bridge and Wireless access points.
Network Interface Card
This provides the hardware interface between a network and computer. It is technically a network adapter hardware in the form factor of an add-in card like a PCI or PCMI card. A number of network interface cards work with wired connection and some others are wireless. The majority of network interface cards support either wired Ethernet or Wi-Fi wireless standards. Ethernet network interface cards plug into the system bus of the computer and have jacks for network cables, and wifi network interface cards have built in transmitters/ receivers. With modern computers many network interface cards are preinstalled by the manufacturer. All networks interface cards have a speed rating like 11 Mbps, 54 Mbps or 100 Mbps that imply the general performance of the unit.
Router
A router is a small physical device that can join multiple PCs together. A router is basically a 3 gateway layer device, this means that it can connect two or more networks and that the router operates at the network layer of the OSI model. Home networks normally use a wireless or wired internet protocol router, internet protocol being the most familiar OSI network layer protocol. An internet protocol router like a DSL or cable modem broadband
A network interface card is already present in the computers. The purpose of the network card is to enable the computers to connect together using a protocol in order to transfer packets of data. In order to connect the computers, a form of connection is required that links the computers. In this case the form of connection used will be ethernet (Science - Opposing Views, 2014).
Paraphrasing (Stallings, 2007) the function of routers is to get the packet to a destination network. The router reads the header created by the Network Layer of the protocol stack on the source computer. The router can be configured to filter by protocol, source
Router is a device for networking that sends packets of data between the networks of a computer. The packet of data is forwarded to routers of the networks that contain the internetwork until the packet is at the destination node. A router can be linked to several data lines from various systems. The router reads the address information in the packet to establish the ultimate destination when the data packet is in any data lines (Liu, 2012).
The OSI Model is a model is used to define how data is theoretically passed on a network. Each layer is responsible and has its own duties for a network. The name of layer 3 in the OSI is the Network Layer. This layer is responsible for creating the paths for the transmission of data across the network. This layer provides routing and switching capabilities, as well as, internetworking, congestion control, and packet sequencing (Beal, 1999).
NIC - A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter, and by similar terms) is a computer hardware component that connects a computer to a computer network
Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.
A network interface card or a NIC is a circuit board or card you can install in your computer so that it can be connected to a network. It allows
Workstation: A workstation is an area accessed by a user. There are many different types of workstations, but the network workstation makes sure that they are connected to an office LAN so they can access other workstations if needed. It can be used for any job, such as gaming designer, video editing, architect ect. The network workstation allows people to share their files to any other workstation as long as they are connected on the LAN.
A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).
This assignment will be mainly about network components and how do they operate, what are their functions and what are their flaws.
A router is a network device, typically connected to a variety of LAN and WAN interfaces, that forwards packets based on their destination IP addresses.
The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.

The Institute of Electrical and Electronics Engineers (IEEE) has developed standards for physical ports and cables that have been generally accepted globally. This greatly simplifies the physical connection work required with only one type of cable needed that will fit any machine’s ports. This further extends to the scalability of a network, allowing additional machines to be connected
• If routers reside at more than one layer, what is the difference between the OSI layers?
