IT & Programming

1. The internet is a global network of interconnected computers that communicate with each other using standardized protocols.

2. Protocols are sets of rules and standards that define how data is transmitted and received over the internet. They ensure that different devices and networks can communicate effectively, regardless of their underlying hardware or software.
Key protocols include:
– TCP/IP (Transmission Control Protocol/Internet Protocol): The foundational protocol suite that governs data transmission across the internet.
– HTTP/HTTPS (Hypertext Transfer Protocol/Secure): Used for transmitting web pages.
– FTP (File Transfer Protocol): Used for transferring files.
– SMTP (Simple Mail Transfer Protocol): Used for sending emails.
– DNS (Domain Name System): Translates domain names into IP addresses.

3. If you connect five computers in a simple network without a router, each computer needs to be connected to every other computer. Each computer will need 4 plugs to connect to the other four computers.

– The total number of cables needed is 10, calculated as follows:
Each computer will connect to other 4 computers.
5 × 4 = 20
– Since connections are two-way (A to B is the same as B to A), divide the total by 2.
20/2 = 10 cables.

(B) – If you use a router, each computer only needs one plug to connect to the router.
– You will need 5 cables, one for each computer to connect to the router.

4. A router is a networking device that forwards data packets between computer networks. It connects multiple devices to the internet or to other networks and directs traffic, ensuring data reaches its intended destination. Routers often include built-in security features, such as firewalls and encryption, to protect the network.

5. Spaced learning is an educational technique that involves breaking down information into small, manageable chunks and reviewing them over increasing intervals of time. This method leverages the spacing effect, which suggests that information is more easily retained when it is studied multiple times over a longer period, rather than crammed in a short period.

To become an expert front-end developer using spaced learning, I intend to do these:
– Identify key skills and concepts I need to master, such as HTML, CSS, JavaScript and frameworks.

– Break down these topics into daily or weekly learning session and allocate specific times for review sessions.

– Consistently work on projects and coding exercises to apply what I’ve learned.

– Periodically revisit previously learned material to reinforce my understanding and identify areas that need more practice.

– Participate in code reviews and seek feedback from mentors or peers to improve my skills.

– Keep up with the latest trends and updates in front-end development to ensure my knowledge remains current and relevant.
