What else can I help you with?
Where is the OUI used?
OUI (Organizationally Unique Identifier) is used in MAC addresses of network devices to identify the manufacturer or vendor of the device. It helps in organizing and managing network traffic, troubleshooting network issues, and ensuring security by identifying the origins of devices connected to the network.
How are the devices connected on a bus network?
Devices on a linear bus network are connected to each other via a wire, usually through a T-connector device. In effect, the devices are "daisy chained" together without any other device connecting them.
Which device sends data packets to all connected devices in a network?
Hub
What is switch hows its work?
A switch is a networking device that connects devices within a local area network (LAN) and facilitates communication between them. It operates by receiving data packets from one device and directing them to the appropriate destination device based on MAC addresses. This process is known as packet switching, where the switch learns the addresses of connected devices and uses a MAC address table to efficiently route the data, minimizing collisions and optimizing network performance.
An isp has a block of 1024 addresses.it needs to be divide the addresses to 1024 customers does it need subnetting?
No. If you have one IP per customer, you don't need to create smaller subnets. (You won't have enough addresses though - the first and last addresses of the block will be the network and broadcast addresses and won't be useable. You'll only have 1022 usable addresses)
What ip addresses would a technician see if a computer is connected to a network device but is not receiving an ip address from the dhcp server?
169.254.1010
What does an empty ARP Cache indicate?
An empty ARP (Address Resolution Protocol) cache indicates that a device has not yet resolved any IP addresses to their corresponding MAC (Media Access Control) addresses. This situation typically arises when the device is newly connected to a network or has recently cleared its ARP cache. As a result, any communication attempts to other devices on the local network will require ARP requests to be sent out to obtain the necessary MAC addresses.
Select the best definition for the network term DHCP?
A protocol that lets one device on a local network, known as a DHCP server, assign temporary IP addresses to the other network devices
Collection of computers and devices connected together?
This is the definition of a computer network. Devices such as routers and bridges create logical network subnets and network domains that computers, printers, and other devices can connect with to join the network.
What is a possible reason that host a and host b are unable to communicate outside the local network?
Because they need a device to communicate with a distant network through. These devices are called gateways, and are normally routers. The hosts on a segment need to have knowledge of the gateway device in order to communicate outside the segment. In most environments, the local network will have an internal addressing scheme, one that is not routable on the internet, so there needs to be a device that can translate the internal addresses (non routable on the internet) into external addresses (routable on the internet). Of course this device needs to be connected to both the internal network and the external network to be able to send traffic between them.
What is a device that shares its resources with other network devices?
One device that is shared on the network is a router. This is the one that will connect the various devices to the shared network.
What is an it address?
An IT address typically refers to an Internet Protocol (IP) address, which is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the device in the network. IP addresses can be either IPv4, consisting of four numbers separated by periods, or IPv6, which uses a longer alphanumeric format to accommodate more devices. These addresses are essential for routing data across the internet and enabling communication between devices.
