  1. 4. (MOdulator-DEModulator) - A device that converts digital data from your computer into an analog signal for transmission over phone lines, cable lines, or other media, and then converts the incoming analog signal back into digital data. It is the device that connects your home or office network to your Internet Service Provider (ISP), A device that's job is to convert digital data from on your computer to an analog signal that can be transmitted on phone lines so that information can be spread and when it reaches the destination it coverts back to digital data and this device connects to your Internet.
  2. 7. arrangement of devices on a communication network that describes the physical or logical layout that the network is arranged in Star is all devices are individual connected to a hub that is the central device, the bus is all devices connected to a single central cable that is reliant for all, a ring is each device is connected to two other devices forming a path where it can survive if one goes down, Mesh is devices being connected to multiple other devices and it being full is being connected to all other devices
  3. 8. - The most common technology used for wired local area networks (LANs). It defines the rules and standards for how network devices transmit data over a physical cable (typically an Ethernet or Cat cable), It is common in LAN networks that uses a cable instead of wireless to comminate data for the internet making it faster and more reliable.
  4. 9. / Client - a client is a device or software that requests a service, while a server is a powerful machine or application that provides that service, a client puts in a request for a needed service, and a server is machine that provides the client's service.
  5. 12. - a system of interconnected computing devices that communicate and share resources like data, printers, and internet access, A group of computers that are connected and share information between one another.
  6. 15. All devices are connected to a single, central cable (the "bus"). A break in the main cable can disrupt the entire network.
  7. 16. A networking device that connects multiple devices (like computers, printers, and servers) within the same local area network (LAN). A switch is "smart" because it learns the address of each connected device and forwards data packets only to the intended recipient, which increases network efficiency, A network device that connects a variety of devices together in a LAN which gains acsesss to the address of each device that is connected and is able to send the information packet to the required destination
  8. 18. Address (Internet Protocol Address) - A unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing. It's essentially the mailing address for your device on the internet, An IP address is a string of unique numbers that is assigned to a device which is used for communication to locate and identify a device and is the internet's mailing address for a device
  9. 19. - The arrangement of elements (links, nodes, etc.) in a communication network. It describes the physical or logical layout of a network
Down
  1. 1. - any device or data point connected to a network that can send, receive, or redistribute information, A point that is connected to a network that gets information then gives it out to the required place outside the network
  2. 2. (Local Area Network) - Local Area Network, is a group of computers and other devices connected in a small, confined area, A LAN is a connection of computers that is in a geographically small area
  3. 3. (Domain Name System) - The internet phonebook. It translates human-readable domain names (like google.com) into the numerical IP Addresses that computers and networking equipment use to locate and connect to each other, A DNS is a service that makes domain names with readable wordls to an IP address that computers and networks can find each other with.
  4. 5. Devices are connected to multiple other devices. A full mesh connects every device to every other device, providing high redundancy and reliability.
  5. 6. All devices are individually connected to a single central device (a hub or switch). If one device or cable fails, only that device is affected.
  6. 10. Each device is connected to exactly two other devices, forming a single circular path for data.
  7. 11. - a networking device that directs data packets between computer networks, allowing multiple devices to share a single internet connection and enabling them to communicate with each other, is a network device that directs data packets for networks so many devices share a signal for the internet.
  8. 13. - A technology that uses radio waves to provide high-speed wireless internet and network connections. It allows devices to connect to a network access point without a physical cable, Wireless communication through radio waves that communicate internet and network connections and allow devices to connect to a network’s access point without having to plug in a cable
  9. 14. - A small unit of data transmitted over a network. All data sent across the internet (such as an email, a web page, or a video) is broken down into these small segments. Each packet contains a portion of the data plus control information (like the source IP, destination IP, and sequence number) that helps it get routed and reassembled at the destination, A small piece of data that is sent of a network across the internet that is broken up into smaller pieces where each piece contains a portion of the data and control information which helps get it to its destination.
  10. 17. (Wide Area Network) - Wide Area Network, a network that connects computers and smaller networks over a large geographical area, A WAN is a connection of computers that is in a geographically large area
