Topic 6 Flashcards
We all use networks and most of us have a LAN network at home that allows us to connect devices together and share resources.
Networks - Hardware
Devices needs it in order to connect a network
Network Interface Controller (NIC)
convert the data signals from the device into data signals that can be transferred across the network.
Network Interface Controller (NIC)
used to be separate cards, but nowadays are built into the motherboard. ________ exist for both wired and wireless connections.
Network Interface Controller (NIC)
Like mobile phones and TVs, wireless networks use radio waves to transmit data.
Wireless Access Point
To set up a wireless, you need a __________ device.
Wireless Access Point
is basically a SWITCH that allows devices to connect wirelessly.
Wireless Access Point
enables a computer to connect to the internet via a telephone line
Modem
Simply broadcasts data to all devices in a network, regardless of the destination.
Hubs
Connects multiple devices in a local network and forwards data to the correct destination.
Switch
*Receives Data Packets – The router gets packets from connected devices.
*Reads the Destination IP Address – It checks where the data needs to go.
*Chooses the Best Route – Using routing protocols, the router decides the best path for the data.
*Forwards the Data – It sends the data to the next device (another router, a switch, or the destination).
*Handles NAT (Network Address Translation) – Routers allow multiple devices in a private network to share a single public IP address.
Router
connect different devices on a network. Today, most networks have cables over a wireless connection as they are more secure, i.e., less prone to attacks, and at the same time carry larger volumes of data per second.
Network Cables/ Cables
are reassembled
Packets
Wi-Fi signals are affected by obstacles like walls, distance and interference will makes them less reliable than a wired connection
Transmission Media
are made of a single copper wire surrounded by a plastic layer for insulation and a metallic mesh which provides shielding from outside interference.
Coaxial Cable
transmit data as light.
Fiber-Optic Cable
is a computer intended for individual use that is faster and more capable than a personal computer.
Workstation
It is a networking device that connects multiple network segments or LANs together. It is typically used to segment traffic and improve performance.
Bridge
