Assalamualaikum to all my viewer .
Today , I want you enjoy about my post and I will talk about my NETWORK



What is the NETWORK ???

a network is a collection of computers and devices connected together via communication devices and transmission media.

Network Topology

What is a network TOPOLOGY ????

A network topology refers to the layout of the computer and devices in a communication network

Two types of layout in the network topology.

1)physical topology

2)logical topology

3 types of network topology :

A network topology that is set up in a circular fashion in which data travels around the ring in one direction & each device on the ring acts as a repeater to keep the signal strong as it travels. Each device incorporates a receiver for the incoming signal & a transmitter to send the data on to the next device in the ring. The network is dependent on the ability of the signal to travel around the ring. When a device sends data, it must travel through each device on the ring until it reaches its destination. Every node is a critical link. In a ring topology, there is no server computer present. All nodes work as a server & repeat the signal. The disadvantage of this topology is that if one node stops working, the entire network is affected or stops working.

Star Topology

In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection. In Star topology every node (computer workstation or any other peripheral) is connected to a central node called hub or switch. The switch is the server & the peripherals are the clients. The network does not necessarily have to resemble a star to be classified as a star network, but all of the nodes on the network must be connected to one central device. All traffic that traverses the network passes through the central hub. The hub acts as a signal repeater. The star topology is considered the easiest topology to design and implement. An advantage of the star topology is the simplicity of adding additional nodes. The primary disadvantage of the star topology is that the hub represents a single point of failure.

Bus Topology

In local area networks where bus topology is used, each node is connected to a single cable. Each computer or server is connected to the single bus cable. A signal from the source travels in both directions to all machines connected on the bus cable until it finds the intended recipient. If the machine address does not match the intended address for the data, the machine ignores the data. Alternatively, if the data matches the machine address, the data is accepted. Because the bus topology consists of only one wire, it is rather inexpensive to implement when compared to other typologies. However, the low cost of implementing the technology is offset by the high cost of managing the network. Additionally, because only one cable is utilized, it can be the single point of failure.

AIM TO EXCEL

1. Believe in Yourself  

Self-confidence is single-handily one of the most important things you can have in your life. If you believe that you can do something that alone gives enough strength to complete the task.

So if you combine your desire for success with your self-confidence and belief in yourself, you will light such a fire that you will have an unlimited drive, which will greatly help you achieve excellence.

2. Learn from the Best ( Role Models)

Rather than doing everything on your own. Try to learn from the best of people who have already done everything that you are doing now. These people who have already achieved success have built-in themselves all the skills and habits required to be excellent and successful and you can learn a lot from them.

3. Work really Hard

Success comes to those who put the work in. So using your strong drive put everything you got into your goal. The more you feed your goal with energy and love the more fruit it will give you.

Also the more focused you stay the better; people tend to work really hard but towards the wrong things. So if your goal is to become a good student and this means you have to also do good in physical education, don‰’t waste all of your energy towards running and working out.

Distribute your energy evenly and focus on the areas which are more important.

4 . Never Give Up

No matter what bumps you face on your journey to excellence. Never give up. Just like goals break down any big problems you face into smaller more manageable chunks and get out there and achieve your goal.
