 THE INTERNET AND CLOUD STORAGE

The term “cloud computing” means performing computer tasks using services provided over the Internet. In cloud computing a company's data and applications are stored at an offsite data center that is then accessed via the Internet (the cloud).

Pros Of Cloud Storage

• Advantage #1: Disaster Recovery (DR) ...
• Advantage #2: Access your data anywhere. ...
• Advantage #3: Low cost. ...
• Advantage #4: Scalability. ...
• Advantage #5: Security. ..
• 
  
• Disadvantage #1: Lack of total control. ...
• Disadvantage #2: Difficult to migrate. ...
• Disadvantage #3: Requires Internet.

The name comes from the fact that the data gets stored on servers - in the cloud. So, I guess it's safe to assume that the cloud is a slang term used by tech industry people to describe the servers and networking infrastructures that allow users to store and access data through the internet.

REFLECTION WRITING ON IP ADDRESS DATE: 18.11.2024

 

WHAT IS INTERNET PROTOCOL (IP) ADDRESS ?

IP address stands for “Internet Protocol address.” The Internet Protocol is a set of rules for communication over the internet, such as sending mail, streaming video, or connecting to a website. An IP address identifies a network or device on the internet. IP rights are important because they encourage creativity and innovation. By giving inventors and creators exclusive rights to their work, intellectual property laws allow them to profit from their investments and recoup their research and development costs.

WHAT IS TRANSMITTING DATA ?

Data transmission is sending and receiving digital or analog data between devices. This can be achieved through different mediums, such as cables, optical fibers, or wireless signals. Data transmission, digital transmission or digital communications is the transfer of data over a point-to-point or point-to-multipoint communication channel. Examples of such channels include copper wires, optical fibers, wireless communication channels, storage media and computer buses.

 ADVANTAGES AND DISADVANTAGES OF PAKETS ?

ADVANTAGES

 Reduces lost data packets because packet switching allows for resending of packets. More cost-effective since there is no need for a dedicated channel for voice or data traffic.

DISADVANTAGES

Delay: Because packets can take different paths, they might arrive out of order, causing a slight delay as the data reassembled. For most things, this isn't a big deal, but for real-time services like video calls, it can be noticeable.

WHAT HAPPENS  IF PAKETS ARE LOST ?

Packet loss will generally reduce the speed of throughput—the actual amount of data that flows through the network—of a given connection. The term latency is a general term referring to many types of delays typically found in the processing of network data. Packet loss is one type of latency.

WHAT IS ACCESSING WEBSITES?

Open access is a publishing model for scholarly communication that makes research information

 available to readers at no cost, as opposed to the traditional subscription model in which

 readers have access to scholarly information by paying a subscription

HOW DOES DATA TRAVELS THROUGH NETWORKS?

The internet has become an integral part of our daily lives, and the way we communicate, work, and access information has changed drastically over the past few decades. But have you ever wondered how data travels through the internet? In this article, we will take a deep dive into the complex system that makes it possible for us to send and receive data across the globe. The journey of data through the internet begins at the source, where it is created or transmitted. This could be a computer, smartphone, or any other device that can send data over the internet. When you type an email, upload a file, or send a message, the data is generated at this end. Once the data is generated, it reaches the network interface of the sending device. This could be an Ethernet port, Wi-Fi antenna, or any other device that enables communication over the internet. The network interface converts the digital data into analog signals, which can travel through the physical medium (cable) to reach the next device. The data now travels through a network of routers and switches, which direct it towards its destination. 

USING CELLULAR NETWORK

A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (such as a base station). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell.

When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.

      INFORMATION COMMUNICATION TECHNOLOGY

                                            

 .WHAT IS ICT?  

 ICT, or information and communications technology (or technologies), is the components that enable modern computing. Among the goals of ICT technologies, tools and systems is to improve the way humans create, process and share data or information with each other. Another is to help them improve their abilities in numerous areas, including business; education; medicine; real-world problem-solving; and even leisure activities related to sports, music, and movies.

What is the importance of ICT

In today’s digital age, it is essential to have knowledge about Information and Communication Technology (ICT). ICT refers to the use of digital technologies to create, store, process, and exchange information, and it has transformed the way we communicate, learn, work, and do business. Here are some reasons why it is important to have knowledge about ICT:

Communication: ICT enables people to communicate and share information across different locations and time zones using digital platforms such as email, video conferencing, social media, and instant messaging. This has made it easier for people to stay connected with friends, family, and colleagues, and has also facilitated global collaboration and networking.

ADVANTAGES OF ICT

• It improves concentration and comprehension. The activities carried out through digital and interactive tools increase student concentration and, therefore, they assimilate concepts more quickly, enhancing learning. This type of tool involves students in more practical learning, with the aim of reinforcing what they have learnt.    
• It promotes student flexibility and autonomy. New technologies promote autonomous learning for students. With the incorporation of digital alternatives such as online courses, each student can learn at their own pace and resources thanks to the flexibility provided digital and connectivity.   
• It encourages critical thinking. The diverse sources of information that technologies provide bring new points of view to students. In this way, information and communication technologies encourage debate and the acceptance of other people’s opinions. In addition, the exchange of thoughts allows students to learn about different cultures.   
• It facilitates communication between teachers and students. The whole educational community has quick access to the same resources. In this way, digital tools allow direct and immediate interaction, without the need to be physically present. This was especially important during the confinement experienced during the 2020 health crisis.
•                                    DISADVANTAGES OF ICT

• Distractions and lack of attention. Digital means opening up unlimited access to multiple resources and sources of information, such as web pages, social networks or chats, and therefore, they take attention away from the subject matter.   
• Excessive impact. Excessive and inappropriate use can lead students to a compulsive relationship with technology, which can lead to an inability to control consumption and, consequently, have adverse effects on the student’s health, social, family and academic life.   
• It reduces the development of other skills. Practices such as writing, public speaking and reasoning may be nullified by the widespread adoption of digital in academic institutions. This has been demonstrated in a recent study conducted by the University of California. The report details that the social skills of the new generations are based on the digital environment, therefore, direct personal communication can be affected.
