Introductionmc13660d373de58ca_1528450127855_0Introduction

The task of the students before the lesson was to learn what a computer network is and what its tasks are.

At the beginning of the lesson the students together with the teacher formulate the definition of a computer network and specify its tasks.

A computer network is a set of computers and other networking devicesnetworking devicesnetworking devices that are connected to one another by transmission channels. It enables the mutual transfer of information and sharing resources.

The elements comprising a computer networkcomputer networkcomputer network:

- hostshostshosts – computers connected to a computer network,

- serversserversservers – computers connected to a computer network operating constantly that provide specified services,

- a transmission channeltransmission channeltransmission channel – a connection between computers that enables data transfer. Telephone and network cables, optical fibres, radio waves and satellite links are transmission channels,

- networking devicesnetworking devicesnetworking devices – network interface controllers, modems, routersroutersrouters, Ethernet hubshubshubs (hubs), network switchesnetwork switchesnetwork switches, access points – devices that mediate data in a computer network,

- software – computer programmes installed on hostshostshosts, serversserversservers and networking devices that enable the operation of devices connected to a computer network.

Task 1

On the Internet, find the images of networking devicesnetworking devicesnetworking devices. Create a simple presentation or a document containing the description of the selected pictures.

How to connect a device to a computer network:

A network interface controller is a device that is used to convert data packets into signals transmitted in computer networks. Network interface controllers are implemented on expansion cards or as devices connected to a USB port. Most of the devices available on the market are equipped with at least one network interface controller. The most popular are wired Ethernet network interface controllers and wireless local area network (WLAN) interface controllers.mc13660d373de58ca_1527752256679_0A network interface controller is a device that is used to convert data packets into signals transmitted in computer networks.

Network administrator:

A network administrator is a person designated in a given organization who is responsible for maintaining the computer network infrastructure. His or her role is to ensure the continuity of the operations and the security of the administered computer network. The position requires a breadth of knowledge in the field of computer and network hardware and software.mc13660d373de58ca_1527752263647_0A network administrator is a person designated in a given organization who is responsible for maintaining the computer network infrastructure.
