Understanding uniform resource locators and domain names is essential for navigating the internet effectively. A Uniform Resource Locator is an address assigned to files on the internet, providing a standardized way to locate and access resources.
Example: https://www.bbc.co.uk/news/technology/index.html
Each part of a URL serves a specific purpose:
Domain names are human-friendly representations of IP addresses, making it easier for users to remember and access websites. Fully qualified domain names specify an exact resource and can only be interpreted one way, always including the server's hostname.
Definition: An IP address is assigned to every computer on the internet and every device that communicates on a network.
Domain Name Servers play a crucial role in translating domain names to IP addresses. Each domain name has a direct relationship with an IP address, and DNS servers store tables of domain names and their corresponding IP addresses.
Internet Registries are organizations responsible for the allocation of IP addresses. They work to protect the world's depleting pool of unallocated IP addresses, ensuring efficient use of this limited resource.
Internet security is a critical aspect of online communication and data transmission. Various measures and technologies are employed to protect users and their information from potential threats.
Firewalls are an essential component of internet security:
Definition: A firewall sits between a device and the internet, regulating the packets that pass through it.
Firewalls can be implemented as hardware or software and often work as proxy servers, performing packet filtering and stateful inspection. Packet filtering involves accepting or blocking packets based on their source IP address or protocol, while stateful inspection examines the contents of a packet before deciding whether to allow it through the firewall.
Encryption is another crucial aspect of internet security:
Various types of malware pose threats to internet users:
To prevent malware infections, users should take precautions such as installing antivirus software, keeping systems updated, and being cautious when opening email attachments or downloading files from the internet. These measures, combined with a solid understanding of internet infrastructure and security principles, can help ensure a safer online experience for all users.
This section explores encryption methods and various types of malware threats. It provides comprehensive information about protecting network communications and preventing malicious attacks.
Definition: Symmetric encryption uses a shared private key for both encryption and decryption.
Highlight: Asymmetric encryption employs four different keys - each device has a private key and a public key pair.
Example: Malware can take various forms including worms , trojans , and viruses .
Vocabulary: Antivirus software serves as a primary defense against various types of malware.
The foundation of internet access lies in the services provided by Internet Service Providers . These companies play a crucial role in connecting users to the vast network of the internet. The role of internet service providers in internet access is fundamental, as they serve as the gateway for individuals and organizations to connect to the online world.
How packet switching and routers transmit data is a key concept in understanding internet infrastructure. Packet switching is a method of data transmission where information is broken down into smaller units called packets. Each packet contains essential components:
Vocabulary: A packet is a container in which data is transmitted over networks, holding the address for the sender and recipient, as well as the intended information for the recipient.
The primary components of a packet include:
Routers play a vital role in directing these packets to their destinations. They use sophisticated algorithms to determine the fastest and most efficient routes for data transmission.
Highlight: Routers hold tables with information relating to the fastest possible routes to certain devices, which they frequently update for maximum performance.
Gateways are used when two networks use different protocols, and packets must be modified to ensure compatibility. This process involves stripping away most of the packet's details, leaving just the contents, and then assigning new sender and receiver addresses to comply with the new protocols.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
