Definition
| -a network that connects computers within a limited area such as an office, school, or home. |
|

Term
| WAP (Wireless Access Point) |
|
Definition
| -a device that allows wireless devices to connect to a wired network using Wi-Fi. |
|
|
Term
|
Definition
| -a type of networking technology that allows computers to communicate with each other within a local area network (LAN). |
|
|
Term
|
Definition
-a unit of data used in Ethernet networks. It consists of several key components:
Destination MAC Address: Identifies the recipient's network interface.
Source MAC Address: Identifies the sender's network interface.
Data: The actual information being sent, limited to 1500 bytes.
Frame Check Sequence (FCS): A value used to check for errors in the transmitted data. |

Term
| MAC (Media Access Control) address |
|
Definition
-a unique identifier assigned to network interfaces for communications on the physical network segment.
-48-bit addresses, usually displayed as 12 hexadecimal characters. For example, a MAC address might look like 00:1A:2B:3C:4D:5E. |
|
|
Term
| OEM ID (Original Equipment Manufacturer ID) |
|
Definition
-The first 6 characters of the MAC address are the OEM ID, which identifies the manufacturer of the network device.
-The remaining characters are unique to each device, ensuring that every network interface has a unique MAC address. |
|
|
Term
| Frame Check Sequence (FCS) |
|
Definition
-a part of the data frame in networking that helps ensure data integrity.
-When data is sent over a network, the FCS is used to check if the data has been transmitted correctly without errors. |
|
|
Term
| IP address (Internet Protocol address) |
|
Definition
-a unique identifier assigned to each device connected to a network.
-It allows devices to communicate with each other over a network, such as the internet or a local area network (LAN). |
|
|
Term
|
Definition
-repeats the signal it receives to all connected devices, regardless of the destination.
-Because it broadcasts data to all devices, multiple conversations can slow down the network significantly. |
|
|
Term
|
Definition
-learns the MAC addresses of the devices connected to it and sends data only to the specific device that needs it, which improves efficiency and speed.
-By directing data only to the intended recipient, a switch allows multiple conversations to occur simultaneously without slowing down the network. |
|
|
Term
|
Definition
| -a base-16 numbering system used in computing to simplify the representation of binary numbers. |
|
|
Term
|
Definition
-a network that connects multiple smaller local area networks (LANs) over large geographical distances.
-Unlike LANs, which are limited to a smaller area like a home or office, WANs can span cities, countries, or even continents. |
|
|
Term
| logical address (IP Address) |
|
Definition
-a unique identifier assigned to each device on a network.
-Unlike a physical (MAC) address, which is hardcoded into a device's network interface card, a logical address is assigned through software and can be changed. |
