- Este tipo de topologia foi muito utilizado nas redes durante os anos 80 e até meados dos anos 90. Uma grande desvantagem era a dificuldade para expansões. Cada vez que um novo equipamento era adicionado à rede, era preciso fazer um "refresh" de cabos para manter a sequência, o que nem sempre era fácil. Outra grande desvantagem era que, ao desconectar um cabo qualquer, a rede inteira ficava inoperante. Own research - by Jose Mariano
- Example sentence(s)
- O GRAFO de uma rede em barramento tem sempre o mesmo aspecto mostrado acima: uma linha contínua de nós, cada um deles ligados a dois outros nós vizinhos, excepto os dois extremos, que têm um único vizinho cada um. - Wimax

- Τοπολογια αρτηρίας είναι ο τρόπος με τον οποίο συνδέονται διάφορες δικτυακές συσκευές πάνω σε μία κεντρική αρτηρία. Own research - by Giorgos Rodopoulos
- Example sentence(s)
- Το πιο συνηθισμένο μέσο υλοποίησης της αρτηρίας είναι το ομοαξονικό καλώδιο . Η συνηθέστερη υλοποίηση δικτύου με τοπολογία αρτηρίας είναι το Ethernet - teacher-nik.freeservers.com
by Giorgos Rodopoulos - Τοπολογία σύνδεσης συσκευών σε τοπικό δίκτυο. Στην τοπολογία αυτή οι συσκευές βρίσκονται συνδεδεμένες σε ένα κοινό επικοινωνιακό φυσικό μέσο (bus). Τα δεδομένα που εκπέμπει κάθε συσκευή, υπό την μορφή πακέτων, διαδίδονται κατά μήκος όλου του καναλιού. Κάθε συσκευή αποδέχεται μόνο τα πακέτα που περιέχουν την δική της ταυτότητα, αναγνωρίζοντας την διεύθυνση προορισμού που περιέχουν τα πακέτα. Το πιο συνηθισμένο πρόβλημα που δημιουργείται στην τοπολογία bus είναι οι συγκρούσεις (collisions) που παρουσιάζονται όταν δύο ή περισσότερες συσκευές προσπαθήσουν να εκπέμψουν ταυτόχρονα πακέτα δεδομένων. - techteam

- A link topology in which all stations are connected in parallel to a medium. These stations are capable of concurrently receiving a signal transmitted by any other station connected to the medium. Manufacturing Automation

- Bus topology has some disadvantages. When there is heavy traffic on cables then bus topology will not work properly. Sometime due to heavy traffic network may stop working. - blurtit
![](https://cfcdn.proz.com/images/wikiwords/small_grey_arr.gif) - With the Bus topology, all workstations are connect directly to the main backbone that carries the data. Traffic generated by any computer will travel across the backbone and be received by all workstations. This works well in a small network of 2-5 computers, but as the number of computers increases so will the network traffic and this can greatly decrease the performance and available bandwidth of your network. - firewall.cx
![](https://cfcdn.proz.com/images/wikiwords/small_grey_arr.gif) - To avoid signal reflection, a physical bus topology requires that each end of the physical bus be terminated. - brainbell.com
