Firewall: A firewall is a security device that is used to monitor and control incoming and outgoing network traffic. Firewalls are used to protect networks from unauthorized access and other security threats.
Cloud networks. This is a type of WAN, but its infrastructure is delivered by a cloud-based service, such as Amazon Web Services. Cloud networks are a standard approach for modern networks.
Mechanical switches were used so that peripheral devices could also be shared. Due to physical limitations (cable length), the devices and computers always had to be very close to each other.

They can perform regular data backups and enforce security measures, such as multifactor authentication, across all devices collectively.
Outro desafio enfrentado pelas redes modernas é este gerenciamento do tráfego. Utilizando o aumento do volume por dados circulando pela Net, é crucial que as infraestruturas por rede sejam capazes de lidar utilizando essa demanda crescente isento comprometer a performance.
It's measured in terms of bandwidth, which is quantified by the theoretical maximum number of bits per second that can pass through a network device.
Ensuring the security of a network is crucial to protect data and resources from unauthorized access and attacks. Key aspects of network security include:
Devices attached to a computer network use IP addresses that are resolved into hostnames through a domain name system server to communicate with each other over the internet and on other computer networks.
This internal IP address is used only for communication between the participants in the local network. For communication on the Net, external IP addresses are used that are automatically assigned by the Internet provider.
Star Topology: In star topology all devices are connected to a central node called hub or switch. The hub controls the flow of data between devices. If one device fails the rest of the network is unaffected. But, if the central hub fails the whole network stops working.
FTP: Protocolo do transferência por arquivos qual permite o envio e recebimento do arquivos entre dispositivos.
These protocols ensure that data packets are sent and received efficiently, without collisions or interference. They help manage t
Transport layer. This layer ensures the stable, sequenced and error-free delivery of data packets. It achieves this by swapping acknowledgment of data reception and retransmitting lost or dropped packets. Typical protocols used at the 男同网 transport layer include TCP and User Datagram Protocol.
