From vast personal experiance working in a computer service store I can say that DLink is perhaps the worst company out of any other competitor. I've had nothing but problems with glitchy drivers and incompatible hardware. They are cheaper, but it's not worth it when half their products don't work with each other.
Linksys makes great network switches, but they can be a bit pricey for their 8-port models.
DLink's hubs are a bit ignored although they'll work just fine. You may want to consider a Netgear hub, however.
People who service Routers, Switches, and any other networking device. they monitor the activity of there network and make sure it functions correctly.
Ethernet switches are used to make possible communication between different network meaning, switches create networks. Also switches use different mechanism of forwarding communication between computers as well as it does not share one channel for multiple computers.
First of all you known about Networking when you make the network in LAN,MAN,WAN and any type of topology. 1- Topologies 2-LAN 3-MAN 4-WAN and the CISCO NETWORKING devices like cables, switches, Routers and entire building computers where you want to make Network.
If they are good enough.
I would try the DLink brand. I have had success with this brand in the past and have been very impressed with their customer service when something went wrong.
So you can make purchases on the PlayStation Store.
The major benefit of a switch over a hub is the increase in the amount of collision domains. This allows a switched network to benefit from full duplex transmissions, negating the need for CSMA/CD, and doubling the potential throughput for each network segment. Switches typically operate at layer 2 of the OSI model, using destination MAC addresses within the Ethernet frame to intelligently filter or forward packets.
Network administrators make around 80,000 dollars per year. Not much, but it's still a good salary. If you go back into college, you may be able to make much more than that.

the central part of the computer network is the server system. There are a number of servers that provide services to the network. There are file servers, email servers, data servers etc that are part of the network, even in a small organization. These servers are connected to either routers or switches which run cales out to the different machines on the network. PC's and printers are usually on this network. There are other specialized machines that make up part of the system like tape drives to back up the network data but I am just outlining the major portions that most folks see. the switches run cables back to the user and the printers. If a server, switch or router goes down it could cause the loss of part or all of the system so they should be locked away from any one just happening by and throwing an on/off switch or running some malicious software on it.
