Understanding how computer networking works

We will talk about some of the more common protocols that you may come across and attempt to explain the difference, as well as give context as to what part of the process they Understanding how computer networking works involved with.

A client Understanding how computer networking works a different computer, such as your laptop or cell phone, that requests to view, download, or use the content.

Many times, administrators configure one interface to service traffic to the internet and another interface for a LAN or private network. LAN stands for "local area network". Co-ordinates all the computers functions by interpreting and carrying out the instruction sent to it by an input device or program.

The Forms To Fill Out Unstructured chats are too carefree — how does the server know what we want to do? A network using a hub can slow down if many computers are sending messages, since they may try and send messages at the same time and confuse the hub.

The client computer asks for a website from the server computer. This level of networking utilizes ports to address different services.

It can build up unreliable or reliable connections depending on the type of protocol used. If the typed data matches then, and only then, the user is allowed to proceed.

This is usually implemented in physical LANs as a way to route requests through one IP address to the necessary backend servers. Using the HTTP format, the above request looks like this: This layer involves the bare software that manages physical connections as well as the hardware itself like Ethernet.

Any machine on the network can transmit messages through the ether at any time, but problems will occur if two or more machines try to talk at once known as a collision. Your email is transmitted as packets orange squares using the Internet Protocol IPillustrated by the orange Internet layer.

The receiver can do the same sums with the data it sees, check the parity bit, and so detect if a mistake has been made. Clients and Servers An important relationship on networks is that of the server and the client. Types of networks Photo: Logging On and Logging Off With SMTP, for example, the client opens a connection and issues commands one at a time such as adding recipients to an emailand closes the connection.

This module covers the concepts of: There are a ton of options out there on the market for routers these days. Because it is a simple transaction, it is useful for simple communications like querying for network resources.

Addressing hardware by the MAC address allows you to reference a device by a unique value even when the software on top may change the name for that specific device during operation. You can even telnet into Memcached to debug it. Many other devices such as cordless phones, baby monitors, microwave ovens while they are turned on, and even poorly shielded wiring either operate or emit the same 2.

A server is a computer that holds content and services such as a website, a media file, or a chat application. Each successive, higher layer abstracts the raw data a little bit more, and makes it simpler to use for applications and users. It sends the message through the Ethernet cable to the hub, then the hub repeats the message to all of the connected computers.

It also allows you to leverage lower layers in new ways without having to invest the time and energy to develop the protocols and applications that handle those types of traffic.

No your 1 router located in the basement is not going to allow you to enjoy connectivity all over your home. It does not establish a connection with the remote host, it simply fires off the data to that host and doesn't care if it is accepted or not.

It creates, maintains, and destroys connections between nodes in a persistent way. A VPN is a private network that uses a public network usually the Internet to connect remote sites or users together.

Wi-Fi operates in the unregulated 2. If either the user identity or password is incorrect the user is prompted to log on again. As data is sent out of one machine, it begins at the top of the stack and filters downwards. It is physically similar to phone cables, but can transport much more data.

When we order a book from Amazon we expect a packing slip describing the order: The transport layer is responsible for handing the layers above it a reliable connection.

How VPNs Work

This guide is operating system agnostic, but should be very helpful when implementing features and services that utilize networking on your server.A basic understanding of networking is important for anyone managing a server.

Not only is it essential for getting your services online and running smoothly, it also gives you the insight to diagnose problems.

An Introduction to Networking Terminology, Interfaces, and Protocols Posted January 14, Networking works by piggybacking a. How Home Networking Works. by Tracy V. Wilson & John Fuller NEXT PAGE. With a home network, you can connect multiple computers in your home. For many families, one computer is no longer enough to go around.

In a household with multiple computers, a home network often becomes a necessity rather than a technical toy. A basic understanding of networking is important for anyone managing a server. Not only is it essential for getting your services online and running smoothly, it also gives you the insight to diagnose problems.
