Explanation of Solution
Computer Network:
A group of computers which communicates among each other over wires or transmission lines is referred as “computer network”.
- The basic type of
computer networks are: - Personal Area Networks (PANs)
- Local Area Networks (LANs)
- Wide Area Networks (WANs)
- Internets
Difference between PANs, LANs, WANs, intranet, internets and the Internet:
Network | Purpose |
PAN | Used to connect the devices which are located about a single person at 10 meters distance. |
LAN | Used to connect the devices which are located in a single geographic location of a company that operates the LAN network. |
WAN | Used to connect the devices which are located in different geographic locations. Two different companies get connected using a WAN network. |
Intranet | It is a network that is used completely within an organization. |
Internets | It is a network of networks. It can connect LAN, WAN and other internets. |
Internet | It is a collection of networks used to send mails or accessing web sites. |
Protocol:
A set of rules and structures for organizing communications is referred as protocol.
Purpose of Protocols:
Computer programs are written by data communication and software vendors, which can implement the rules for specific protocol.
Key difference of a LAN:
A key distinction of LAN is that all the computers should be located in an organization which controls the LAN network. This means, the organization can route cables wherever required to connect the computers.
Purpose of the components in SOHO (Small Office/ Home Office) LAN:
The computers and printers are communicating among each other using the combination wired and wireless connections.
- For wireless connection, 802.11 standard protocols have been used for data transmission. This standard specifies an “over-the-air” interface between a wireless consumer and a base location or between two wireless consumers.
- For wired connection, 802.3 standard protocols have been used for data transmission. It also defines how messages are wrapped and processed for wired transmission over LAN network.
IEEE 802.3:
The IEEE 802.3 is a protocol used to connect wired LAN. This standard, also referred as “Ethernet”, requires hardware features like wire which carries signals...
