Data packets colliding with one another when being sent through repeaters is an easy way to explain a collision domain. This collision only includes a section of a network.
You can't eliminate collision in a broadcasting domain. What you can do is to increase the number of collision domain within a broadcasting domain by using more switches. this will improve your network traffic because the more the collision domain, the better is your network in terms of data transmission performance.
A collision domain is a physical network segment where data packets can collide with one another when being sent on a shared medium.A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions.A collision domain is sometimes referred to as an Ethernet segment.
A computer network can be segmented physically but also logically. A collision domain is one of the logical network segments in which the data packets can collide to each other. One of the most common protocols used when referring to a collision domain is the Ethernet protocol. Collision domains are often referred as 'Ethernet segments'. The term of 'collision domain' is also used when describing the circumstances in which a single network device sends packets throughout a network segment and forces every other device in that network segment to pay attention to those packets.

Switch work's full-duplex mode, but HUB work's on Half-duplex mode. each port of switch is a different collision-domain, but HUB is single collision-domain.
If an access point receives data from a client station, it sends an acknowledgment to the client that the data has been received, this acknowledgment keeps the client from assuming that a collision occurred and prevent a data retransmission by the client.
A hub (or L2 switch) performs data bridging/switching/forwarding at the OSI Layer 2 level for data destined to another address on the same subnet. For data to be forwarded to another subnet, that data must be routed at the OSI Layer 3 level which is performed by a Router (or L3 Switch). Routers collect various information about other networks it can forward traffic to and from, what routing protocols are used and which path(s) to forward that data to.
A collision domain is a logical network segment where data packets can "collide" with one another for being sent on a shared medium, in particular in the Ethernet networking protocol. This is an Ethernet term used to describe a network scenario wherein one particular device sends a packet on a network segment, forcing every other device on that same segment to pay attention to it. A broadcast domain is a logical network segment in which any computer or other device connected to the network can directly transmit to any other on the domain without having to go through a routing device, provided that they share the same subnet address and are in the same VLAN, default or installed. More specifically, a broadcast domain is the area of the computer network composed of all the computers and networking devices that can be reached by sending a frame to the data link layer broadcast address. A very basic network that uses hubs rather than switches or routers is like a post office clerk checking the mail. One clerk looks at each letter to confirm that the mail is not for themselves.
