ITNET LESSON 1 - PART 1

network

is word-of-mouth communication

network

where ideas are passed from person to person. It is a practice that people have learned as soon as they can speak.

cellphone

uses radio waves or microwaves signals for communication

telephone

uses a wire-based technology.

cellphone/telephone

Both of them can link to the world through vast networks through the use of another communications equipment.

cellphone/telephone

Another network that people master at an early age

network communication

1. Word-of-mouth communication

2. Telephone based technologies

3. Computer Networks (and digital devices)

advantages of computer networks

• Computer networks are based from telephone network communication technology and also make use of specialized equipment to connect networks.

• Unlike telephones, computer networks can do more, as it can transmit data from far flung places, can support video streaming and more

• Exchange of information is similar from how a person would communicate with another person through word of mouth, the only difference is that it is done digitally

Local Area Network (LANs)

Pertains to printing machines, computers, and other digital electronics that shares a hardware and software resources that are located close to each other. Its coverage can only connect setups like: small confined space like a typical household, a single department floor or small firm.

Metropolitan Area Network (MANs)

Can cover a greater range than a LAN with a distance spanning from about 30 miles (equivalent to 48 kilometers). This type of network has the capability to link several LANs within municipalities, or cities.

Wide Area Network (WANs)

the largest network that can connect numerous LANs and even MANs across a distance that can exceed more than 30 miles (equivalent to 48 kilometers).

Example: the Internet. It can link multiple smaller networks from different parts of the world.

Personal Area Network (PAN)

Falls under the LAN spectrum and can connect devices from a range of distance of up to about 33 feet (equivalent to 10 meters). It is smaller than a LAN and has two forms, Cabled PAN and Wireless PAN (WPAN).

Examples of devices a PAN can connect are: Smartphones, Personal Computer and handheld devices like a Bluetooth speaker.

Campus Area Network (CAN)

Falls under the MAN sub-category. It can link multiple LAN and can cover the same range as a MAN can reach. This network is owned and managed by a single organization.

Ex. Harvard University having its own servers and network connection equipment’s set up and exclusively managed by them with little to none help from third party network providers.

Enterprise Area Network (EAN)

This has the same features as WAN as it can link different types of networks belonging from different organizations from different parts of the continent. A network is considered as this if it is owned and managed by a single corporation or group that can support a network bigger than MAN.
