A network must use a common language or set of rules to be able to communicate with other networks. These rules are standardized by committee and are an agreed upon set of rules.
These rules are known as protocols, and are widely published.
A protocol is a set of rules describing some behavior. In order to communicate in a common manner, the sender and receiver have to agree on the "language" of communication. A protocol states what those rules are, and because they are a standard, everyone agrees and knows what to expect.
A network protocol defines rules and conventions for communication between network devices. Protocols for computer networking all generally use packet switching techniques to send and receive messages in the form of packets.For more detail www.shreejournalist.blogspot.com
You can use bluetooth, a simple wired connection, or wifi to connect your computers to a network.
An Ethernet cable should be used for enabling a host computer to communicate with other computers or electronic devices. The Ethernet cable is usually attached through a modem to each device, or the device can be wireless such as in Wi-Fi capabilities.

An ad-hoc network is a wireless network in which all connections are wireless. The only devices required are wireless network interface cards in all of the devices that want to participate in the network.

The meaning of Computer network is focusing on sharing data and peripheral devices like printer, scanner, and other devices.
Ad hoc mode:An Ad-hoc network allows each device to communicate directly with each other. There is no central Access Point controlling device communication. Ad-hoc networks are only able to communicate with other Ad-hoc devices, they are not able to communicate with any Infrastructure devices or any other devices connected to a wired network. In addition, Ad-hoc mode security is less sophisticated compared to an Infrastructure mode network.Infrastructure mode:An Infrastructure mode network requires the use of an Access Point. The Access Point controls Wireless communication and offers several important advantages over an Ad-hoc network. For example, a Infrastructure based network supports increased levels of security, potentially faster data transmission speeds and integration with a wired network.

The acronym CSMA CD stands for Carrier Sense Multiple Access with Collision Detection. CSMA CD is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously.
