Open framework:
A framework which is associated with the system and is prepared for correspondence.
Shut framework:
A framework which isn't associated with the system and can't be spoken with.
PC Network:
It is the interconnection of different gadgets, for the most part named as Hosts associated utilizing numerous ways to send/accepting information or media.
There are likewise various gadgets or mediums which helps in the correspondence between two unique gadgets which are known as Network gadgets. Ex: Router, Switch, Hub, Bridge.

The format design utilizing which gadgets are interconnected is called as system topology. For example, Bus, Star, Mesh, Ring, Daisy chain.
System Topology-Diagram
OSI:
OSI represents Open Systems Interconnection. It is a reference model that indicates measures for correspondences conventions and furthermore the functionalities of each layer.
Convention:
A convention is the arrangement of rules or calculations which characterize the way how two elements can impart over the system and there exists diverse convention characterized at each layer of the OSI model. Not many of such conventions are TCP, IP, UDP, ARP, DHCP, FTP, etc.
Extraordinary IDENTIFIERS OF NETWORK
Host name:
Every gadget in the system is related with an extraordinary gadget name known as Hostname.
Type "hostname" in the order prompt(Administrator Mode) and press 'Enter', this shows the hostname of your machine.
IP Address (Internet Protocol address):
Likewise, known as the Logical Address, is the system address of the framework over the system.
To distinguish every gadget in the internet, Internet Assigned Numbers Authority (IANA) relegates IPV4 (Version 4) address as a one of a kind identifier for every gadget on the Internet structural engineering jobs.
Length of the IP address is 32-bits. (Henceforth we have 232 IP tends to accessible.)
Type "ipconfig" in the order brief and press 'Enter', this gives us the IP address of the gadget.
Macintosh Address (Media Access Control address):
Otherwise called physical location, is the one of a kind identifier of each host and is related with the NIC (Network Interface Card).
Macintosh address is appointed to the NIC at the hour of assembling.
Length of the MAC address is : 12-snack/6 bytes/48 bits
Type "ipconfig/all" in the order brief and press 'Enter', this gives us the MAC address.
Port:
Port can be alluded as a legitimate channel through which information can be sent/gotten to an application. Any host may have various applications running, and every one of this application is distinguished utilizing the port number on which they are running.
Port number is a 16-piece whole number, thus we have 216 ports accessible which are ordered as demonstrated as follows:
PORT TYPES RANGE
Notable Ports 0 – 1023
Enrolled Ports 1024 – 49151
Fleeting Ports 49152 – 65535
Number of ports: 65,536
Range: 0 – 65535
Type "netstat - an" in the order brief and press 'Enter', this rundowns all the ports being utilized.
Attachment:
The extraordinary mix of IP address and Port number together are named as Socket.
Scarcely any more ideas
DNS Server:
DNS represents Domain Name framework.
DNS is essentially a server which interprets web locations or URL (ex: www.google.com) into their comparing IP addresses. We don't need to recall all the IP locations of every single site.
The order 'nslookup' gives you the IP address of the space you are searching for. This additionally gives the data of our DNS Server.
ARP:
ARP represents Address Resolution Protocol.
It is utilized to change over the IP address to its comparing Physical Address(i.e.MAC Address).
ARP is utilized by the Data Link Layer to distinguish the MAC address of the Receiver's machine.
RARP:
RARP represents Reverse Address Resolution Protocol.
As the name proposes, it gives the IP address of the gadget given a physical location as information. Be that as it may, RARP has gotten out of date since the opportunity DHCP has arrived into the image.
