a set of computers or devices connected to each other with the ability to exchange data.
computer network
is the arrangement of the elements of a communication network.
Network topology
It is usually a small network constrained to a small geographic area
Local Area Network (LAN)
A computer network in which the computers connected may be far apart, generally having a radius of half a mile or more
Wide Area Network (WAN)
a wireless distribution method for two or more devices that use high-frequency radio waves and often include an access point.
Wi-Fi
Wi-Fi
Metropolitan Area Network (MAN)
a computer network for interconnecting devices centered on an individual person’s workspace.
Personal Area Network (PAN)
a network topology in which nodes are directly connected to a common linear half-duplex link.
Bus topology
A network setup where each computer and network device are interconnected with one another, allowing for most transmissions to be distributed even if one of the connections goes down
Mesh topology*.
a network configuration in which device connections create a circular data path.
Ring topology
In this configuration, every node connects to a central network device, like a hub, switch, or computer
Star topology
a type of connector commonly used for Ethernet networking.
RJ-45
a node that broadcasts data to every computer or Ethernet-based device connected to it.
hub
a device that is used at the Access or OSI Layer 2; also, it can be used to connect multiple hosts (PCs) to the network.
switch
wiring pattern is recognized as the preferred wiring pattern for this standard because it provides backward compatibility to both one-pair and two-pair USOC wiring schemes.
T568B
a device that analyzes the contents of data packets transmitted within a network or to another network.
router
is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network.
wireless router
standard matches the older AT&T 258A color code and is the most widely used wiring scheme. It is also permitted by the ANSI/TIA/EIA standard, but it provides only a single-pair backward compatibility to the USOC wiring scheme.
T568A
is a type of CAT where one end is T568A configuration and the other is T568B configuration. Pin 1 is crossed with Pin 3 and Pin 2 is crossed with Pin 6.
crossover cable
A popular type of cable that consists of two unshielded wires twisted around each other
Twisted pair cable
10BASE-T*:
Cat 5.
100BASE-TX
: Cat 5e.
1000BASE
Cat 6
Refers to the planning of the implementation of a computer network infrastructure
Network design
a numeric/symbolic number or address that is assigned to any device that seeks access to or is part of a network.
IP address
a sequence of characters that uniquely names a wireless local area network (WLAN).
Service Set Identifier (SSID)
a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area
Wi-Fi hotspot
is the strategy used to partition a single physical network into more than one smaller logical sub-networks.
Subnetting
a networking hardware device that allows other Wi-Fi devices to connect to a wired network.
a facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area
a unique identifier assigned to a network interface controller (NIC)
MAC address
is also a hardware identification number that uniquely identifies each device on a
MAC address
is a brand name for a group of server operating systems released by Microsoft.
Windows Server
is a specialized operating system for a network device such as a router, switch, or firewall.
Network Operating System (NOS)
a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
Network Operating System (NOS)
a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.
Dynamic Host Configuration Protocol (DHCP)
a feature of the Microsoft Windows NT family of operating systems that controls the working environment of user accounts and computer accounts.
Group Policy
are used together to redirect the path of local folders (such as the Documents folder) to a network location, while caching the contents locally for increased speed and availability.
Offline files
a location on a network server used to store a computer username, password, and other information.
User profile
refers to a software or operating system feature that allows a personal computer’s desktop environment to be run remotely on one system, while being displayed on a separate client device.
Remote desktop
a device or unit featuring a number of jacks, usually of the same or similar type, for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner.
patch panel
a device used to conjoin two pieces of metal by deforming one or both in a way that causes them to hold each other.
crimping tool
can determine IP addresses, identify polarity, connected port, and link connectivity.
Network cable tester
a hand tool used to connect telecommunications and network wires to a patch panel.
Punch down tool
