You've decided on a niche for your expertise and now need to spread the word. In this article you'll find a variety of relatively simple ways to gain mass exposure.
Radio Interviews
Hundreds of radio shows seek knowledgeable and interesting guests to satisfy their listening audiences. With the onset of satellite radio , internet radio and podcasting, the number of hosts seeking guests grows daily. You need not be a celebrity to secure a radio interview. Plenty of opportunities exist for individuals with knowledge in specialized areas.
Carrier Sense Multiple Access with Collision Detection helps limit the number of collisions, but by dividing one large collision domain into smaller collision domains, we can further reduce or actually eliminate the number of collisions. That's where switches come in!
A collision domain is defined as a group of hosts whose data can be involved in collisions if they transmit at the same time. If three PCs are all on the same network segment , that's a collision domain. To many newcomers to networking, it sounds like you?d rather have one large collision domain than multiple smaller ones. That?s what I thought as well when I started! What you must keep in mind is that the smaller the collision domain, the smaller the number of hosts in the domain ? and the fewer hosts we have in a collision domain, the less chance we have of collisions.
And wouldn?t it be great if we could create a collision domain with only one host? Well , we can, thanks to switches!
Traditional switches run at Layer 2 of the OSI model, with many new switches able to operate at both the data link (L2) and network (L3) layers. Switches help to eliminate the chance of collisions because each port on the switch is actually its own little collision domain!&n. |
