Defination of NetBIOS

Net Bios
 
(Network Basic Input/Output System) is a program that allows applications on different computers to communicate within a local area network (LAN). It was created by IBM for its early PC Network, was adopted by Microsoft, and has since become a de facto industry standard.
 
 

Name Resolution

Today, NetBIOS is used to support legacy NetBIOS applications but is also widely used for NetBIOS name resolution. Since NetBIOS was the first major standard for PC networks, computers were named according to the NetBIOS format, which identifies a machine by a unique 15-character name. NetBIOS machines periodically broadcast their names over the network so that Network Neighborhood or My Network Places can catalog them.

Datagram and Session Modes

NetBIOS is generally defined as a session layer protocol in the protocol stack, supporting two modes: a fast Datagram mode that does not guarantee delivery and a Session mode that establishes a connection and guarantees delivery. See NetBIOS over TCP/IP, WINS and LMHOSTS file. 

 

 






 

interface metric

There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings. To change the priority of the connections: Open your Adapter Settings (Control Panel\Network and Internet\Network Connections) Click Alt to pull up the menu bar.

To configure the Automatic Metric feature: In Control Panel, double-click Network Connections. Right-click a network interface, and then click Properties. Click Internet Protocol (TCP/IP), and then click Properties.
 

Definition of subnetting

Definition of subnetting
 
A sub network, or subnet, is a logical, visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address.

Defination of Internet

The Internet is a global network of billions of computers and other electronic devices. With the Internet, it's possible to access almost any information, communicate with anyone else in the world, and do much more.






Differences between IPv4 and IPv6

Differences between IPv4 and IPv6

 The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). IPv4 provides an addressing capability of approximately 4.3 billion addresses.

 

 

 

 

 

 

 

 

 

 What is IPv4 -- Internet Protocol Version 4? 
IPv4 (Internet Protocol Version 4) is the fourth revision of the Internet Protocol (IP) used to to identify devices on a network through an addressing system. The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks

IPv4 is the most widely deployed Internet protocol used to connect devices to the Internet. IPv4 uses a 32-bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses).  With the growth of the Internet it is expected that the number of unused IPv4 addresses will eventually run out because every device -- including computers, smartphones and game consoles -- that connects to the Internet requires an address.
A new Internet addressing system Internet Protocol version 6 (IPv6) is being deployed to fulfill the need for more Internet addresses.


What is IPv6 -- Internet Protocol Version 6?
IPv6 (Internet Protocol Version 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP) reviewed in the IETF standards committees to replace the current version of IPv4 (Internet Protocol Version 4).

 

 

Define Work group

WORKGROUP

Work group is a group who share data via a local network.























Workgroup has some more defination



Registered jack

Registered jack

Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables. The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard.

 

 

local area network

Definations

A computer network that links devices within a building or group of adjacent buildings, especially one with a radius of less than 1 km

 

 

 

 

 

 

 

 

 A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building[1] and has its network equipment and interconnects locally managed. By contrast, a wide area network (WAN), not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links
