Computer networking was influenced by a wide array of technology developments and historical milestones. Ĭomputer networks support many applications and services, such as access to the World Wide Web, digital video and audio, shared use of application and storage servers, printers and fax machines, and use of email and instant messaging applications.Ĭomputer networking may be considered a branch of computer science, computer engineering, and telecommunications, since it relies on the theoretical and practical application of the related disciplines. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol.Ĭomputer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanisms, and organizational intent. Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment. They are identified by network addresses and may have hostnames. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialized or general-purpose hosts. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. Computers use common communication protocols over digital interconnections to communicate with each other. NOTE: I am using Home wireless router in my Packet tracer topology.A computer network is a set of computers sharing resources located on or provided by network nodes. My challenge now is that after successfully configuring the laptop to use the wireless connection of the router, whenever I try to access a website, for example: skillsforall.srv or, etc, it comes up with a notification: Host name unresolved. I can access the default gateway address from the web browser in the desktop option and it leads me to the wireless router settings. I have configured the wireless connection of the laptop and the router and they work fine. I have done the configuration of the desktops and laptop setting the DHCP to automatic configuration. The cable model and the television are separately connected to the coaxial cable splitter using a coaxial cable. I connected the router to a cable modem using another copper straight-through cable. I connected the two desktop computers to the router using a copper straight-through cable, I have a wireless router, 2 desktop computers, a laptop with a wireless interface card, a television, a cable modem and a cable splitter. I did a home connection using a wireless router and client.
