Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics

(FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from services‚ upgrades of equipment and maintenance of the new network? What are the next best areas to install and where will an FTTH network require

Network Hardening Unit 8 Assignment 1 It is very important to go through the process of hardening. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I picked the network layout 1-the workgroup . First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have some good anti-virus software on the workstations. You also need a hardened image for

Improving Network Topology Draw the topology of the network that you are currently using. Be sure to include addressing structures‚ network architecture‚ and include devices such as core switches‚ workgroup switches‚ firewalls‚ routers‚ and other network devices. Analyze the security of the topology and then draw a proposed new topology. Be sure to include security detection systems as well as security zones. Kazakhstan International School had implemented their network infrastructure since 2007

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.
