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 new wave of connecting to the Internet. These lines allow connections at higher speeds and better quality that an ordinary phone line. May require additional hardware added to the existing phone line or the addition of a totally new port. 56K: The present standard for access to the Internet. It refers to how many kilobits of information can be transferred through the line per second.
What it was found in (or on) is one of the computers linked to the Internet. Computers on the Internet may use one or all of the following Internet services: * Electronic mail (e-mail). Permits you to send and receive mail. Provides access to discussion groups often called Listservs® after the software they operate under. * Telnet or remote login.
Getting Ip's:-- To see the ip all computers you are connected to (web servers, people attempting to hack into your computer). Go to dos (start>run>type command) and run the netstat command. Type netstat /? for details. Type netstat -r at the command prompt to see the ip of all computers you are connected to In MSN (and other programs) when you are chatting to someone everything you type goes through the MSN servers first (they act as a proxy) so you see their ip rather than who you are chatting to.
• Describe the use of digital signatures to verify identity on the internet. • Explain the purpose and potential risk associated with cookies. Internet Internet is computers network connected around the World via dedicated servers. When your computer is connected to the internet you can send, received all kinds of information such as text, graphics, voice, programs and video. The Internet history began with development of the computers.
First came intranets, which are sites designed for use only by company employees. Now, many companies are creating their own Virtual Private Networks (VPNs) to accommodate the needs of remote employees and distant offices. A typical VPN might have a main Local Area Network (LAN) at the corporate headquarters of a company, other LAN's at remote offices or facilities, and individual users connecting from out in the field. Basically a VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. Instead of using a dedicated, real-world connection, such as leased line, a VPN uses "virtual" connections routed through the Internet from the company's private network to the remote site or employee.
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).
All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54). Traffic A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway.
The WAN is control by a network provider like cablevision and use a lot LAN to provide internet service. In conclusion the network system has expand the internet because by sending signal where it is connected users are able to access the internet any time th... ... middle of paper ... ...any computer that is connected to the network. The internet can’t do that but it could help send data making different from a network because it could send it anywhere in the world. The network of home has limited of how far they could send their information depending on what type network system it is install. In conclusion the internet and network are different and they work together to provide user with the data individual might need from World Wide Web.
Networks/ Internet Paper This paper will be defining a network and discusses different types of networks such as LAN and WANs. This also be telling the common internet use like why we use it so much in are life’s this paper will tell how to connect to the internet and telling and be telling the different types of internet websites. A network is a collection of computers and devices connected, often wirelessly, Vi communications devices and transmission media. When a computer connects to a network, it is online. Networks allow users to share resources, such as hardware, software, data, and information.
