✅ What “knowing about computers” typically means for a web developer: Operating systems: Familiarity with Windows, macOS, or Linux. File systems and terminals: Using command line tools, navigating file structures. Networking basics: Understanding how the internet, IPs, DNS, and HTTP work. Security awareness: Basic understanding of things like SSL, firewalls, and secure coding practices. Software tools: Proficient with code editors (e.g., VS Code), browsers, version control (Git), and development servers. 📊 So how many web developers “know about computers”?

It sounds like you're describing a resource or website aimed at helping developers understand more about their computer systems. If you're looking to create or find such a site, it could include: their functions. 2. **Operating Systems**: Guides on how different operating systems work and how to navigate them. 3. **Command Line Tools**: Tutorials on using command line interfaces for system management and development tasks. 4. **Development Environment Setup**: Instructions for setting up development environments for different programming languages. 5. **Troubleshooting Tips**: Common issues developers might face and how to resolve them. 6. **Performance Optimization**: Tips on optimizing computer performance for development tasks. 7. **Security Best Practices**: Information on keeping a development environment secure. 8. **Resource Management**: How to manage system resources effectively while developing.

Let's Talk About Net-Work_ing!

What are Protocols???
What is it? Role/Importance Terms/Vocabulary Example Visual
Protocols a set of rules that determines how data is trnsmitted between multiple devices in the same network. It is the key or cordinating devices in networks.
  • HTTP, HTTPS
  • FTP
  • SMTP, POP3, SMTP
  • TCP, IP, UDP
  • And Many More...
 It's like speaking the same language. It's computer language. Communication between web browsers and servers.
Not human readable. CNP work in this field.
What are Protocol Layers???
What is it? Role/Importance Terms/Vocabulary Example Visual
Protocol layers are based on the models OSI which has 7 layers that take on a specific role when communicating on the internet. It is the key or cordinating devices in networks.
  • Physical
  • Application
  • Presentation
  • Network
  • Data Link
  • Transport
  • Session
  • TCP/IP Model 4 layers
    • Application
    • Transport
    • Network
    • Internet
 Examples for each.
Network Interconnection/ Internet Protocol is What??
What is it? Role/Importance Terms/Vocabulary Example Visual
Network interconnection consists of the conectinon the networks based on different protocols. IP defines unique addressed for the network and host.
  • IP
  • MIN
  • Datagram Protocol
  • TCP
  • Internet Application Protocols
 Internet is a global system of interconnected computer networks.

The Surface Pro 8 will come in configurations that offer some seriously powerful components. The Intel Core i7-1165G7, for example, is a new quad-core Tiger Lake processor with a max turbo frequency of 4.70GHz.
Pair that with 32GB of RAM and you have a very capable productivity machine – in a thin and light tablet formfactor. Exciting stuff. Of course, for many people that kind of spec will be overkill, which is why we expect the Surface Pro 8 to come in a range of configurations as well. Check out the Full Article on the Newest Surface Pro

How does The Internet Really Work???

"The internet is often called a network of networks. What does that mean? Well, in computer terms, a "network" is two or more computers that can communicate. So computers on the internet can communicate."

Five Basic Components of Computer Operating Systems

The Modern Day Toaster

5 Components of the Operating System Explained using a Toaster

  • Input- Bread Loader
  • CPU-
    • Power supply & Container lower the bread
    • Once Lowered, the locking mechanism holds the bread in place
    • The 'memory' keeps the timing request
    • Electricy generates heat to toast the bread
  • Output- Toast pops up, and Wah-la producing the output... TOAST!

Computer Operating System

  • Input- Takes in the user's request
  • CPU
    • CU
    • Memory
    • ALU
  • Output-
