| The name of the PC connected to the network is managed by a database called DNS (Domain | ||||||||
| Name System). DNS links the IP address assigned to each PC with the domain names, and | ||||||||
| enables a user to specify a PC to access. |

IP Address | An identification number assigned to each PC connected to the network. This is used for com- | ||||||||

| There are 2 types of IP address, namely Global IP Address and Local IP Address (Private IP | ||||||||
| Address). |
|
|
|
|
|
|
| |
| Global IP Address | : Just as separate IP addresses are required on a network, this is also | |||||||
|
|
| required for all PCs that are connected to the Internet throughout the | ||||||
|
|
| world. Such an IP address is known as the Global IP Address and is | ||||||
|
|
| usually assigned by the Internet service provider. | ||||||
| Local IP Address | : Separate IP addresses can be used freely within networks that are not | |||||||
|
|
| connected to the Internet (eg. within a family or company).This is known | ||||||
|
|
| as the Local IP Address. |

DHCP | This is a method that automatically assigns IP addresses on the network. | ||||||||
(Dynamic Host Control Protocol) | The DHCP server will automatically assign an IP address to a PC when it is connected to the | ||||||||
| network. |

Subnet mask | A mechanism that manages a network by segmenting it into multiple virtual networks (subnets). | ||||||||

Default Gateway | Hardware and software that are used mutually for the translation of different protocols during | ||||||||
| communication of a PC with one that does not belong to the same network. In Windows, setting | ||||||||
| of a default gateway is required when setting the IP address. |
|
| ||||||
|
| ||||||||
Protocol | A set of rules used for communication of PCs or devices via the network. | ||||||||
|

Workgroup | A group that is set up among a small number of PCs in a work unit to ease reference of data on | ||||||||
| other PCs. It will be difficult to manage if there are a few hundred | ||||||||
| sharing the same network. In this case, management by setting up workgroups will be neces- | ||||||||
| sary. |
