What is a Network Address?

A network address is also known as the numerical network part of an IP address. This is used to distinguish a network that has its own hosts and addresses. For example, in the IP address 192.168.1.0, the network address is 192.168.1.

Examples of Network IP Address

The Internet Assigned Numbers Authority (IANA) reserves the following IP address blocks for use as private IP addresses:
  • 10.0.0.0 to 10.255.255.255.
  • 172.16.0.0 to 172.31.255.255.
  • 192.168.0.0 to 192.168.255.255.

IP Versions :
IPv4 - Internet Protocol Version 4 
Internet Protocol version 4 (IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet, and was the first version deployed for production in the ARPANET in 1983. It still routes most Internet traffic today,[1] despite the ongoing deployment of a successor protocol, IPv6. IPv4 is described inIETF publication RFC 791 (September 1981), replacing an earlier definition (RFC 760, January 1980).

IPv6 - Internet Protocol Version 6 


Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4.[1] IPv6 became a Draft Standard in December 1998, and became an Internet Standard on 14 July 2017.[2]

HOW TO GET BINARY DIGIT/ HOW TO MAKE NETWORK ADDRESS?

*BINARY DIGIT HAS A TOTAL OF 255

Classes of IP Address :

ClassAddress rangeSupports
Class A1.0.0.1 to 126.255.255.254Supports 16 million hosts on each of 127 networks.
Class B128.1.0.1 to 191.255.255.254Supports 65,000 hosts on each of 16,000 networks.
Class C192.0.1.1 to 223.255.254.254Supports 254 hosts on each of 2 million networks.
Class D224.0.0.0 to 239.255.255.255Reserved for multicast groups.
Class E240.0.0.0 to 254.255.255.254Reserved for future use, or research and development purposes.

What are the different types of Cables?

The First type of cable is the Twisted pair
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility.

Another type of  Twisted pair is the  STP 
Shielded Twisted Pair (STPCableSTP is similar to UTP but with each pair covered by an additional copper braid jacket or foil wrapping. This shielding helps protect the signals on the cables from external interference.


Another type of Twisted pair is the UTP

UTP stands for Unshielded Twisted Pair cableUTP cable is a 100 ohm copper cable that consists of 2 to 1800 unshielded twisted pairs surrounded by an outer jacket. They have no metallic shield. This makes the cable small in diameter but unprotected against electrical interference.

The Second type of cable is the Coaxial cable


Coaxial cable, or coax is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield.

The Last type of cable is the Fiber optic cable


An optical fiber cable, also known as a fiber optic cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light.

This are the different types of cables hope my blog helps!

What are the types of Network Topologies?

Types of Topologies

What is Network Topology?
Network topology is the arrangement of the elements of a communication network. Network topology is the topological structure of a network and may be depicted physically or logically

The 1st type of network topology is:

BUS Topology



Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called Linear Bus topology.
The 2nd type of network topology is:

RING Topology



It is called ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first. Exactly two neighbours for each device.
The 3rd type of network topology is:

STAR Topology


In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.
The 4th type of network topology is:

MESH Topology


It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other. Mesh has n(n-1)/2 physical channels to link n devices.
There are two techniques to transmit data over the Mesh topology, they are :
  1. Routing
  2. Flooding

MESH Topology: Routing

In routing, the nodes have a routing logic, as per the network requirements. Like routing logic to direct the data to reach the destination using the shortest distance. Or, routing logic which has information about the broken links, and it avoids those node etc. We can even have routing logic, to re-configure the failed nodes.

MESH Topology: Flooding

In flooding, the same data is transmitted to all the network nodes, hence no routing logic is required. The network is robust, and the its very unlikely to lose the data. But it leads to unwanted load over the network.

The5th type of network topology is:

HYBRID Topology


It is two different types of topologies which is a mixture of two or more topologies. For example if in an office in one department ring topology is used and in another star topology is used, connecting these topologies will result in Hybrid Topology (ring topology and star topology).
These are all the types of Network Topologies hope it helps!
Also thank you for viewing my blog! It helps alot. :)

What are the types of computer network?

Types of Networks:
1st is the LAN

Image result for LAN
A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.

2nd is the WAN
Image result for what is wan network

A wide area network is a telecommunications network or computer network that extends over a large geographical distance/place. Wide area networks are often established with leased telecommunication circuits.

3rd is MAN
Image result for man network
A metropolitan area network is a computer network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network but smaller than the area covered by a wide area network.

4th is PAN
Image result for what is pan network

A personal area network is a computer network for interconnecting devices centered on an individual person's workspace. A PAN provides data transmission amongst devices such as computers, smartphones, tablets and personal digital assistants.

This are the types of networks! Thank you for viewing my blog and I hope it helps! :)

How to be a Responsible Netizen?

"Think before you click" every responsible netizens should know. Because the internet should be used for research and for communicating / being connected to other people / family members around the world. Nut many are irresponsible who uses the inter for cyber bullying, viewing inappropriate pictures/videos for their age. But how can we really be responsible netizens? to be responsible netizens we should use the internet wisely because one wrong post can change everything. If you don't want that to happen then be responsible use the social media by not sharing fake news, by not using it for cyber bullying. To avoid sharing fake news verify that news because once u shared it, it might ruin our reputation that's why we should use the internet for only communicating/being connected with other people's and using it for researching. These are the ways on how to be responsible netizens.
