Topology

STAR-Bus

The best topology is ring topology.

Star is the next best after ringr, and then bus, which is pretty old, but not too expensive.

Full mesh topology is theoretically the best since every device is connected to every other device, thus maximizing speed and security. These, however, are quite expensive to install. The next best would be tree topology, which is basically a connection of stars.

A typical network consists of one or more hubs, switches and routers. They all do similar jobs, however hubs are cheaper because all traffic from one port is broadcast across all other ports. They are "dumb".

Switches are more intelligent (and thus more expensive) and will quickly "learn" which IP addresses are connected to which ports. When a message is initially broadcast across all ports for a given IP address, only one port will respond (if at all), and the switch will then associate that port with the IP address for all future messages, reducing congestion across all other ports. This is why whenever a new machine is introduced to the network (or an existing machine goes offline), there is often a "lag" on the network while the switches figure out the new topology.

A router is the same as a switch but it is also programmable; it is really a computer in its own right. Routers typically provide two or more network interfaces allowing two or more otherwise separate networks to be linked. The router acts as the gateway between those networks. Your home broadband router is a typical example, linking your home network (the local area network) to the Internet (the wide area network). A side-effect of routers is that a machine outside the LAN cannot initiate communications with a local machine; the local machine must initiate all communications outwith the LAN. As far as the WAN is concerned, only the router is visible, but the router uses network address translation (NAT) to route legitimate communications to the correct local machine. All illegitimate communications are simply ignored. A router typically provides a hardware firewall which can be configured to limit the type of (legitimate) communications that may be permitted either to or from the local area network.

Switches, hubs and routers may be daisy-chained or arranged in a star configuration, or a combination of the two. Each switch is linked to one or more network access points and computers connect to the network via these access points.

Access points can also be made available using Wi-Fi, utilising Wi-Fi extenders or repeaters as necessary to increase the range.

Wired connections are typically achieved using CAT5 or CAT5e cabling (8-core, twisted-pair), however network switches are typically linked via CAT6 or, in some cases, fibre optic cabling.

A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.

The main network topolgies are: Bus- consist of running cables from one PC or file server to the next, like links on a chain. Ring- a continust path for dtat with no logicial beginning or ending point and thus no terminators

Star- the oldest communication design method in network technology. Star- Bus Hybrid Star Ring Hybrid Mesh

There are several advantages to a mesh network topology. First, it is fault tolerant; since there is no gateway, nodes can connect to each other with no regard to the state of the rest of the network. In addition, nodes can create their own paths through the network because there is no gateway computer.

One disadvantage to a mesh topology is that setup time can be quite time consuming.

There is actually more than three topologies for networking. Network topologies are categorized into the following basic types: * bus * ring * star * tree * mesh More complex networks can be built as hybrids of two or more of the above basic topologies.

If the hybrid network is designed right, it is the second-best (after full-mesh) topology you can have. A well designed hybrid topology, called so because it combines two or more other network topologies together, strengthens everything you want; speed, reliability, efficiency, etc., and weakens everything else.

Their biggest, really their only, disadvantage is how difficult they can be to design. Hybrids can get so complicated that, no joke, their designers have no clue as to how they work, all they know is that they do work. Their mysterious inner-machinations, or what a mathematician would call a non-linear design, makes them quite hard to troubleshoot, but if they're built right, there won't be any reason to troubleshoot.

Ring, Star, Bus, Mesh.

Star topology is considered as best due to the following reasons

1.There is a central hub in which each individual system is connected.Suppose if one system fails it does not affect other system.This is the major advantage of star topology.

2.Secondly,it requires minimum cabling for the network

Network topology is the way a computer network is set up and arranged, Examples for possible topologies include ring, star, bus, and line. Each of these topologies have their advantages and disadvantages, with star being the most common in today's world.

Two words: cheap and easy. Having only one main cable connecting all of the stations together drastically reduces the time and cost of installation and makes troubleshooting particularly easy.

A baseball will curve better down on a flat plain (at lower elevation above sea level). This is because the curving is caused by the ball contacting the air and pushing the ball in a particular direction. A ball's particular spin, speed, how the ball's stitches meet the air, etc will determine specifically how it will change direction when the air pushes against it. Imagine a baseball thrown in a vacuum where there is no air. The ball would not curve at all because there is no air to push on it. The ball would continue on a straight path, influenced only by gravity pulling it downwards. On a mountaintop, there is less air in a given volume of space than there is on a flat plain (at a lower elevation). Therefore, there will be less air to push on a thrown baseball when it is thrown on a mountaintop. Since there is less air to push on it, it will curve less well when thrown on the mountaintop. So it will curve better when thrown down on a flat plain.

No. The relationship is:

weight = mass x gravity

Mass causes both weight, and inertia. Weight is the force of attraction by gravity, and also depends on the gravitational field, not just on the mass.

For more information, check the Wikipedia article "Mass versus weight".

Hierarchical topology is best used in large organizations or data centers where scalable and efficient network management is essential. It organizes network components into layers, typically comprising core, distribution, and access layers, facilitating better performance, ease of troubleshooting, and easier implementation of policies. This structure is ideal for environments requiring high availability, redundancy, and effective traffic management. Additionally, it supports various types of devices and services, making it suitable for complex networking needs.

logical channel

A ring topology requires several key components: network devices (such as computers and printers) that are connected in a circular fashion, a network interface card (NIC) in each device to enable communication, and cabling to connect each device to its two adjacent devices in the ring. Additionally, a token-passing mechanism may be used to control data transmission, ensuring that only one device sends data at a time to prevent collisions. This setup allows for efficient data transfer but can be disrupted if any single device or connection fails.

In a bus topology, data transmission typically uses protocols such as Ethernet, specifically the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. This protocol allows devices to detect when the bus is free and transmit data while monitoring for collisions. If a collision occurs, devices stop transmitting and wait for a random time before attempting to resend. Other protocols, like Token Ring, can also be adapted for bus topologies, but CSMA/CD is the most common.
