1. Networking

Networking

• Computer Networks and How the Internet Works – A network is a group of devices linked to share data. Each device has an IP address. Data is cut into numbered packets. Routers pass each packet hop by hop towards its address, and TCP puts the packets back in order. DNS turns a website name into an IP address. Clients ask, servers answer. Firewalls, passwords, updates and encryption keep a network safe.

2. HTML

HTML

• Web Development: How HTML, CSS and JavaScript Build a Web Page – A web page is a set of text files. The browser (client) asks a server for them using a URL and HTTP. HTML gives the page its structure: headings, paragraphs, links, images, lists, tables and forms. CSS gives style: colours, fonts, spacing and layout. JavaScript gives behaviour: it reacts to clicks and changes the page. Responsive design makes one page fit both phones and computers. Good pages are also accessible, fast and safe.
