Router: is a hardware device used for the interconnection of computer networks that ensures the routing of data packets between them or determine the best route to take.
Mac Address: A Media Access Control address (MAC address) is a unique
identifier assigned
to network
interfaces for
communications on the physical network segment. MAC addresses are used for
numerous network technologies and most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.
HUB: A
hub is a device that allows you to centralize the network cabling and to enlarge. This means that the device receives a signal and repeats this signal emitting it through its different ports.
IP: An IP address is a numeric label that identifies, in a logical and hierarchical, with an interface (an element of communication / connection)
of a device (usually a computer)
within a network
using IP (Internet Protocol),
which corresponds the network layer of TCP / IP. This number must not be confused with the MAC address is a48-bit identifier to uniquely identify the network card and not depend on the connection protocol or network used. The IP address can change very often changes in the network or the device within the network manager to assign IP addresses,
decide to assign an IP(for
example, DHCP), this form of IP address assignment is called dynamic IP
address (usually abbreviated as dynamic IP).
Internet sites which by their nature need to be connected, generally have a fixed IP address (commonly fixed IP or static IP), this does not change with time. Mail servers, DNS, FTP servers and public web pages must necessarily have a fixed or static IP address, since this form is allowed its location on the network.
The computers are connected through their IP addresses. However, we human beings is more convenient to use another notation easier to remember, as domain names, the translation between them is resolved by the domain name servers DNS, in turn, facilitates the work in case of change of IP address, because you can just update the information in the DNS server and other people will not learn as they continue accessing the domain name.

LAN: A local area
network, local network or LAN (local area network of English) is the interconnection of one or more computers and peripherals. Its size is physically limited to a building or an environment of 200 meters with repeaters could reach the distanceof a field of 1 kilometer. Its most widespread application is the interconnection of personal computers and workstations in offices,factories, etc..
Topology: Topology (Greek τόπος, "place" and λόγος, "study") is the branch of mathematics devoted to the study of those properties of solids that remain
unaffected by changes continuas.1 is a discipline that studies the properties of topological spaces and continuous functions. Topology is concerned with concepts such as proximity, number of holes, the kind of consistency (or
texture) having an
object, compare and classify objects and also other attributes which include connectivity,
compactness, or metrizability nonmetricity so on.
NIC: A network interface controller (Also known as a network interface card,
network adapter, LAN adapter and by like terms) is a computer hardware component connects a computer to that a computer network.
Whereas network interface controllers Were Commonly Implementedon expansion cards plug Into That computer bus, the low cost and ubiquity of the Ethernet standard MOST newer computers Means That Have a network interface built Into the motherboard.

Protocol: In computing, a protocol is a set of rules used by computers tocommunicate with each other through a network via message exchange. This is a rule or standard that controls or enables communication in its simplest form, can be defined as rules that dominate the syntax,
semantics, and synchronization of communication. The protocols can be implemented by hardware,
software, or a combination thereof. At its lowest level, it defines the behavior of a hardware connection.
Switch: A switch is a digital device logical interconnection of computer networks operating in the data link layer of the OSI model. Its function is to interconnect two or more network segments, similarly to the network bridges, passing data from one segment to another in accordance with the destination MAC address of the frames on the network.
A switch in the center of a star network.
The switches are used when you want to connect multiple networks, fusing into one. As the bridges, as they function as a filter in the network, improve the performance and safety of local area networks.

Wan: A Wide Area Network (WAN) is a telecommunication network
that covers a broad area (i.e., any network that links across metropolitan, regional,
or national boundaries). Business and government entities utilize WANs to relay
data among employees, clients, buyers, and suppliers from various geographical
locations. In essence this mode of telecommunication allows a business to
effectively carry out its daily function regardless of location.[1]
This is in contrast with personal area networks (PANs), local area networks(LANs), campus area networks (CANs),
or metropolitan area networks (MANs)
which are usually limited to a room, building, campus or specific metropolitan
area (e.g., a city) respectively.
