By use of TCP/IP, several computers on small network in a department can use these protocols in conjunction with other protocols on a single LAN. In this protocol suite, the IP components helps in routing form the small LAN in that department to regional and also to the global internet. TCP/IP is made up of layers which enable it to perform its tasks. The IP part is responsible of moving packet from one node to the other based on the destination IP address. This IPs are mainly assigned by the internet authorities to service providers and thus making it easier for computers to communicate because the IPs assigned to them makes them unique and thus packets can move from source to destination all over the world.
Connectivity devices refer to several different device types, all of which are used to connect cable segments, connect two or more smaller networks (or subnets) into a larger network, or divide a large network into smaller ones. The term encompasses repeaters, hubs, switches, bridges, and routers. Network applications Network applications are software programs that run between different computers connected together on a network. Some of the more common uses of network applications include using a web browser program to find content from the World Wide Web, or using an e-mail program to send e-mails over the Internet.
Analysis of Internet Protocols and Infrastructure Introduction: Network: Anything reticulated or decussated at equal distances, with interstices between the intersections. - A Dictionary of the English Language SECTION : 1 1.1 WHAT IS A NETWORK? A) What is a network? A network is simply a collection of machines connected in some way that allows them to communicate with each other and share information. To do this the machines have to be connected in some way that allows communication, and have an agreed upon a language to talk when they do communicate.
TCP/IP Overview When designing networked applications one key protocol stands out as the foundation for making it possible. That protocol is TCP/IP. There are many protocols out there that allow two applications to communicate. What makes TCP/IP a nice protocol is that it allows applications on two physically separate computers to talk. What makes TCP/IP great is that it can do with two computers across a room or across the world.
The packet-switching nature of the Internet gives it sufficient speed and flexibility to support real-time communication, such as sending messages to other people in a chat environment (IRC). Every packet is written in a particular protocol language, called TCP/IP, which stands for Transmission Control Protocol/Internetworking Protocol. This protocol is the common language of the Internet, and it supports two major programs called File Transfer Protocol (FTP) and Telenet. FTP lets the transfer files from one Internet computer to another. Telnet lets a person to log into a remote computer.
The internet refers to the massive network of computers stretching all over the world. The word internet also found its origin through this, the word comes from the two words interconnected and network. Though we can all with each other through internet, all the computers are not connected to the one and same mega computer. For each network there are one or several computers that hold the information that is needed to access all the information. This arrangement is known as the client-server architecture.
• Network Adapter: is an important component of making up LANS, which is used to connect a network and convert computer data into electronic signals. In order to move data packet to and from network interface cards to different shared channels, network adapter associates with network access element named Media Access Control ... ... middle of paper ... ...s to translate the packet back into meaningful form and utilize it with suitable application. Technologies Used to Build a LAN According to Mitchell (2016), WiFi or Ethernet is a modern local area network used for connecting with different devices. Typically, a traditional Wi-Fi LAN operates a single or a few of wireless access points for providing a service to devices within the signal range. The role of access point is to manage networking traffic from connected devices.
The gateway to the Internet from your home computer is through an ISP. To get to the Internet through an ISP you have to have a modem dialup, ISDN (Integrated Services Digital Network), DSL (Digital Subscriber Loop), cable modem, wireless, or leased line. These methods provide a variety of speeds to connect the Internet, without one of these methods you will not be able to connect to the Internet. Transmitting information using the Internet can be a little confusing to understand. As mentioned earlier, the Internet is a network of networks and there is a network protocol that allows computers electronically describe data (Scott's Newsletter).
For example, your Internet server provider may provide you with a PPP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses the Internet protocol and is designed to handle others. It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the OSI reference model, PPP provides layer 2 (data-link layer) service. Essentially, it packages your computer's TCP/IP packets and forwards them to the server where they can actually be put on the Internet.
Angel Santizo Routers A router is a device used to connect two or more networks and move data between them. Routers work at the network layer of the OSI model. Routers are mainly used to connect networks and keep traffic between them under control. Companies that make routers include: Belkin, Cisco and Linksys. How do they Work?
