  1.  @anonymouscode1635  Pretty ignorant comment. You've never worked in IT support have you?

  2. Do you have any IT and/or computer knowledge or experience? if not, you may need to start elsewhere. Computer networking is not exactly for people brand new to the IT industry. If you know absolutely nothing about computers, you may want to start with the ITF+ (IT Fundamentals). Its a certification for people brand new to the IT field and/or are not sure if IT is a good fit for them. From there, you can move onto the A+ which deals with PC troubleshooting and repair and is for entry-level IT jobs. Then, from there you can go onto the Network+ (this certification) or if you want to go more advanced, CCNA (Cisco certification).

  3. You don't necessarily need to have computer networking knowledge to be a programmer, but it does help to have some knowledge. This video is primarily for people who are interested in the Net+ certification so a lot of it likely won't be relevant to you.

  4. wow dude. Maybe you don't realize it, but not everyone knows this stuff. You and I and plenty other people already know how to use computers. But there are many people who rarely use computers or who have never used one. The arrogance....

  5. No. That's because the ISP doesn't use an ethernet cable. They cannot run an ethernet cable all the way from their central office to your home. Ethernet has a length limit of about 330 ft. (~100 m). A lot of ISPs started as phone or cable companies long before internet was even common. Instead of replacing every single phone cable or coax cable, they use those same cables to deliver internet to your home. That's why you need a modem. It is like a "bridge" that connects your home to your internet provider's network. The router is what routes (hence the name) the IP packets to and from your home network. Most ISPs will sell/rent/give you a gateway device which includes a modem, router, wifi, and network switch in one box.

  6. Not really. This is primarily intended for people who don't have much knowledge about computers in general.

  7. For the vast majority of computer users, the graphical interface is much easier and simpler to use than the command line. However, if you want to go deep into how your computer works or if you're interested in higher level IT jobs, knowing your way around a command line is invaluable. As an example, let's say you want to create 20 folders. With the graphical interface, you right click an empty part of your desktop, and create a new folder. Pretty easy. However, you will quickly realize that doing that 19 more times is very tedious. With the command line, you can write out a script that will create 20 folders at once. I don't have a particular script to show you, but it can be done that way. It is tedious and does take a long time and practice to get good at it. However, if you do become proficient in the command line, you'll find that certain tasks are very quickly achieved through there rather than the graphical interface.

  8. Do you have any IT experience? If not, then you want to start with the basics like the A+ or ITF+.

  9. The modem connects your home network to your ISP's network. You can think of it as a bridge. In most home networks, your ISP sells/rent/gives you a gateway unit which includes a modem, router, and wifi all in one box.

  10.  @promiseemeka9587  Self-study. There are countless good resources online that talk about computer networking. Professor Messer, Network Chuck, David Bombal all have great videos on many networking topics.

  11. I would say no. If you have little to no knowledge of computers, I would store with more basic stuff. There's the IT Fundamentals from CompTIA (ITF+) which is meant for people who are brand new to the IT field and need the fundamentals and/or are not sure if the IT field is a good choice for them. After ITF+, you can move onto the A+ and the Net+ if you want. The network+ is intended for people who want to get into networking, but at that point, it greatly helps if you already know about IT.

  12. In the real IT world, you'll be dealing with acronyms all the time. No one says Dynamic Host Configuration Protocol. DHCP is much easier to say. No one says Internet Protocol version 4 or Internet Protocol version 6: IPv4 or IPv6.

  13. There's nothing preventing you from hosting a website without buying a domain name. The problem you will quickly realize is how do you access your website if you don't have a domain name? You would just type in your public facing IP address into your browser. That would work. However, again, you will quickly realize that the vast majority of people don't want to type in a bunch of numbers. You can try it yourself at home. Setup a web server and a basic website. On your router, you will need to forward ports 80 and 443 (for https) to your web server. Once that's done, find out what your public IP address is. You search on Google "What is my IP address" and it will tell you. Use your cellphone's data connection and type in your public IP address into the address bar of your browser. If all goes well, you should be able to get to your test website from a different internet connection.

  14. You have to understand that binary deals with 2 possible values: 0 or 1. Remember in grade school where you learned about place values? Like the 1's column, 10's column, hundreds column? With binary, its the same concept, except that instead of going by powers of 10, you go by powers of 2. So you have the 1's column, 2's column, 4's column and so forth. If you just have the 1's column, your possible numbers are: 0 or 1 If you have 2's columns, your possible numbers are 0 (00); 1 (01); 2 (10); 3 (11) If you have 4's columns, your possible numbers are 0 (000); 1 (001); 2 (010); 3 (011); 4 (100) And so on. Remember place values and the rest will make more sense.

  15. Yes. For the most part, you don't need to use the terminal. Most modern Linux distros are generally good when it comes to ease of use. However, there may be times where in order to fix something or install something, you have to use the terminal. This may vary depending on your computer. I feel that its a bit more tricky on laptops since the hardware they use is not always supported out of the box. Again, this depends on your computer.

  16.  @Garrus1995  As I said, IT is an extremely broad field with many sub-fields. If you don't want to commit to programming, you can look into jobs like network administration, servers/systems admins, etc. These jobs don't deal with programming, but are still in IT. This falls more into IT support where you're supporting users/customers and the applications and services their business uses. Its not always glamorous or as high paying as the high-end programming jobs, but its a good field. For these jobs, you typically start at the bottom: help desk. Again, it isn't glamorous, but you can usually work your way up.

  17. I think just being moderately familiar with computers in general should be good enough.

  18. You can't get a street address from an IP address. It may show your approximate geographical location like town/city, but not your street address. This is information only your internet provider knows. I wouldn't worry too much about it; just be cautious and not click random links.

  19. This video is a good basic start. I would move onto videos on how to use Microsoft Windows: basic file management, navigating the system, etc I don't have any particular videos or courses to recommend though.

  20. If you think its too hard now, look at how it used to be 2-2.5 decades ago. It has massive improvements in that time.

  21. A VPN is not necessarily used to protect your online identity or provide anonymity. The purpose of a VPN is to connect a network to another network. Let's say you have a company with an HQ in Sacramento. You have a few branch offices in Chico, Reno, and Sutter. All those branch offices will need someway of connecting to your network at HQ. With a VPN server, you can have those branch offices connect to your HQ network. All the employees at those branch offices will appear, network-wise, as if they were on the main network and will have access to the same network resources as if they were at HQ. It just so happens that companies started marketing VPN services, which is what a lot of people think of as VPNs. If you use a VPN service, you're essentially connecting to that provider's network and your traffic in turn goes out from their network to wherever you're going.

  22. PS/2 is not hot-pluggable. As I understand it, the PS/2 controller is extremely simple and has no concept of hot-swapping. So if you disconnect the PS/2 mouse and plug in a different mouse, it may not work since the protocol wasn't designed to operate that way. In reality, most modern PCs don't use PS/2 anymore so if your PC still has one, it likely is very old.

  23. I work in K12 IT. I had a teacher a few years ago put in a tech ticket because her laptop screen developed a dark spot in the center. I took a look at it and noticed that section of the lid was warped. It looked almost melted. She tells me she didn't know what happened. So I replace the screen and lid and return it a few hours later. Then she tells me she lit a candle and put it right behind the laptop screen.... I thought to myself "You're lucky we don't charge you for this stuff".

  24. It can help, but it won't be enough. CCNA is CIsco-specific while this is for the Network+ which is a vendor-neutral certification. You can still learn a lot and most of it can translate into Cisco, but you need to know the Cisco-specific stuff as well.
    2
  25. Well they kinda are. They're very fast, but have to be programmed in very specific ways to achieve results.
    2
  26. Not really. Its not a bad course, but it doesn't go over the Cisco part of the CCNA. The core knowledge is still the same, but you have to know how to configure Cisco routers and switches using their command set.
    2
  27. It is possible, but not likely just with this video. This video does cover a lot of information, but there is still much more to learn in terms of how to actually setup a network.

  28.  @anonymouscode1635  Are you still that arrogant?
    2
  29. There's a Wikipedia page - List of words about computers - that is pretty good

  30. What do you mean it is kinda outdated? The core networking concepts don't change much in years....
    1
  31. You ok?
    1
  32. 🤦 You're in the wrong video then dude. This video is specifically about computer networking and the theory behind computer networks. It doesn't go over how to setup servers and things like that as that is outside of the scope of this video.

  33. What computer system are you using? Windows? Mac? a linux distro?
    1
  34. I suppose it depends on what you plan on doing? Do you want to work in IT or do you just one more general computer knowledge?
    1
  35.  @saydhen6079  I would look for videos about Microsoft Office if you're interested in writing documents. I would also look for general Windows basics videos to get a general idea of how Windows works. I don't have any videos in particular to recommend though.

  36. What?
    1
  37. And your question is??

  38. Kinda hard to help without more info..... What exactly did you put the wrong username into??

  39. Download the software from the manufacturer and install it.

  40. You could, but you would need to take apart the keyboard and all of the keys and mechanisms. That can get pretty time consuming. There are a few better ways of doing this: Use a can of compressed air or a vacuum cleaner for electronics to blow/suck any debris/particles; grab a trashcan and shake the keyboard vigorously over the trash can; use a lightly damped cleaning wipe to clean the keyboard and wait a few minutes for it to fully dry off.
    1
  41. Its a start.
    1
  42. You can use it to learn the core networking knowledge, but you still need to know the Cisco-specific stuff for the CCNA. Network+ is a general networking certification. CCNA is specific to Cisco.
    1
  43. Bro is on wrong video??
    1
  44. Technically yes you would use a switch. It just so happens that home routers have a built-in switch so most people don't buy dedicated network switches unless they need more ethernet connections. And plus most people now use Wi-Fi anyways so its less likely that people plug their computers and devices to their router over ethernet.

  45. what are you blabbering on about??
    1
  46. lmao. Yet you're using a computer of some sort...

  47. It doesn't make sense. If you already have a CCNA certificate, you should already know plenty about how networks work and Cisco-specific stuff. The Net+, which is what this video covers, is more basic than the CCNA. If you want to go deeper into networking, look into CCIE or other more expert-level networking courses.

  48. Most typical home routers have 4 ethernet ports. You just plug your PCs and devices into those ports. If your router doesn't have any for whatever reason or you don't have enough, you'll need to buy a network switch.

  49. You don't necessarily need the A+ prior to taking this test. However, it you should ideally be fairly adept with IT concepts already prior to taking this certification test.

  50.  @Designated-Kwon-Daegun  🤦🤦🤦 That's one of the issues of ChatGPT. Its not entirely accurate. Your answer isn't necessarily inaccurate either, but it depends on the context. In the context of networking, a node is basically any device that sends/receives network traffic. ChatGPT should be used with skepticism, not your sole source or "authoritative" source for information.
