[2025] Belajar Network Fundamental - Part 1 | Belajar Jaringan Komputer

Hi, welcome friends to the LMS IDN class, especially for the material to learn computer networks from the basics. So later we will discuss the material that is still basic related to the fundamental network related to maybe the introduction of how many devices and also the introduction of physical 1 layer later here, yes, before the introduction first, friends, I'm Agung Presety, later I will talk about the material more or less for this fundamental network or learning the basic computer network,

before that maybe we get to know more about IDN, what is IDN or IDN

or ID Networker, ID Networker is one of the training center institutions or certifications from national to international where we have several fields, especially in the fields of networking, programming, sysadmin, cybersecurity, IOT robotics and also digital marketing where we have more or less 40 more training options, friends and also for

For alumni who have done training at IDN, there are approximately 35,000 people here. Because we have started in 2008, so it's been quite a while. Also for corporate training or offices that trust IDN to come or called IHT, In-house training, there are approximately 500 clients from corporate. That's a little bit about ID Networker's introduction, friends.

In addition to the introduction and introduction, we will also discuss the outline material. There are approximately 8 outline materials that we will discuss later. The first is the career opportunity as a network engineer. The second is the introduction of the computer network. We first introduce what a computer network is. Then there is also an introduction of OC Layer, TCP/IP Layer, IP Protocol, port, MAC address, and IP address.

later in the middle of the MAC address and IP address session, of course, in subnetting, we will try to demo how the device can communicate and there is also a layer 1 UTP, layer 1 WebRoot, we will also demo on the UTP and STP layer 1, so wait for the video, friends,

okay, don't take too long, let's go straight to the first material, namely career opportunities as a network engineer, so what are the opportunities that we can enter or opportunities that we can enter in the network engineer from here, so the first thing we try first, this is the same network engineer, so the network engineer himself later is one of the jobs that is really a job by professional IT, which is responsible for implementing

network, network planning, management and also secure our computer network so that it runs more optimally. That's really the role of the network engineer, friends. And the reason why we have to enter the network engineer too and why is it that the network engineer is like that? Because now, friends, if we look

Whatever information, whether we want video call, shopping, live streaming, online sales, etc. Now it's all online. Because of that, we need internet connection.

that's where we can enter friends, the role of network engineers is there, we can make the signal, we keep the signal active 24/7 there, even up to 365 days there, that's why this network engineer plays an important role in the internet connection there, friends

There are also several hierarchies of levels in the network engineer career path. There are entry level, mid-level, senior level, and specialist. The entry level is usually support or network support. There is also a mid-level network engineer.

The senior level is usually a network architect, a senior network engineer, and a pre-sales engineer, or commonly known as L3. There is also a specialization here, which is people who work specifically. So network engineers are just

more focused on one field of matter, for example, there is a network security engineer, so the task is to secure the network from various kinds of attacks, whether it's a DDoS and so on, there's also cloud networking, we'll focus on routing cloud devices there, whether it's AWS and so on, and there's also SDN, software defense network,

there will be each of them here later, you can call it defnet, there are several career paths that exist in this network engineer, friends, if you want to enter this network or later in other jobs, you have to prepare several

preparation, friends, the first is soft skills, of course, so the knowledge of soft skills and so on must be prepared first communication and also hard skills there, so if we only have soft skills, we have communication, we don't have hard skills, it's the same there, but if we have all three, it can be a great opportunity for us, we can configure, we can

We do a safe troubleshooting configuration, but if we have a difficult communication, it will be even more difficult. There will be some cases. Therefore, the third skill that is here, we must master it all.

That's the preparation for you to become a network agent. And also later on, other preparations, you have to prepare the material as well. Or the hard skills here. The hard skills later have several levels, friends. From level 1 to level 10. The first level is the fundamental network or network fundamentals. What we will discuss at this time is level 1, friends. There will be routing and switching, network security, design, wireless network, monitoring and troubleshooting, cloud computing, splitting, collaboration,

So the first thing we learn is the fundamental network

Okay, if we have discussed it earlier, we will also try to discuss the opportunities on the network later. So on the network itself later, there will usually be a minimum requirement, friends. So when you register for work and so on, sometimes there is a requirement. Minimum, yes, sometimes certification is there. That's why I put it here. Is certification important? The answer is 50-50.

What does it mean? It means that if we look at some opportunities or jobs or some interfaces that open jobs, they usually open the minimum CCNA or CCNP certification. So the minimum is CCNA or CCNP.

And also here if we look at the second one, hold Cisco Certified Network Associate or CCNA certified is a must. So you must have CCNA too. CCNA is one of the certifications that are in Cisco, Cisco Certified Network Associate.

Then there is also here having a CNA, CGNP, MDCNA, and CNGA certificate will be more liked So if we increase our chances, we can enter a company if we have a certificate there

There will be several matem tracks for this certification, there are entry level, mid level, and advanced level. The entry level, for example, there are COMTIA Network Plus, HCI DataCom, CCNA, MTCNA, and GNG. Then the mid level is usually more focused on the professional level, if we look at PPP, it will be in MTCNA.

at the M level or Mikrotik Certified Network Associate, it will not enter the mid-level again. Usually we will discuss it related to MTCRE and other enterprises. At the mid-level, the professionals will be Cisco Certified Network Professional, GNCE AEP, the professional level is from Juniper, HCIP, the professional level is from Huawei. The advanced level is also the same, there is Mikrotik, Cisco, and GNC H.

Expert, the E is Expert, that's some of the hierarchies of the certification, you can try to chase it from the entry level first, we collect the certification from below first here.

This is the certification track from MikroTik, friends. If you want to take the MikroTik track, you can take the MTC or the previous one. MikroTik Certified Network Associate, then you can continue to other enterprises. You can take RE, Routing Engineering, or Traffic Control Engineering. That's an example if you want to take the focus track to MikroTik. The highest one is at MTC.

From Cisco itself, it is divided into different levels, so there is an entry level, associate, professional, and expert level. The entry level is CCST, Cisco Certified Support Technical. The associate level is CCNA, Cisco Certified Network Associate, and the professional level is still divided into two. There will be a CCNP Enterprise, CCNP Service Provider, or SP.

There are also the data center, security and collaboration So if you want to focus on some subjects later

The separate is in the part of the CCNP, friends. So, friends, you want to take the focus to the data center, to the data provider, later on the professional level of the CCCO here. The expert level is also available, friends. There is the CCIE Enterprise Infrastructure or AI there. CCIE Enterprise Wireless and there are still many more. SP, DC, there is also security and collaboration there, of course.

Juniper is also the same, there is an expert level. For the career part of a network engineer, sometimes we take Enterprise Routing and Switching and also Service Provider Routing and Switching. The second combination here we have to take is CNGIA Junos.

or Juniper Network Certified Associate. If you want to continue to the GNCIS or the specialization level, the professional and expert must follow the hierarchy here. Usually what is taken or most often taken is these two here, Enterprise and Service Provider. If you want to continue to another field, you can also go to the Data Center Cloud and so on.

Huawei is also the same, there are many fields, there is Datacom, this is the most often taken, there is Huawei HCI Datacom, HCIW Datacom, and that is also often taken in Datacom, so if you want to learn something else, for example cloud computing, there is also a test track here,

That's some of the tracks from the certifications of some vendors at the same time, whether it's a Huawei vendor, a Juniper vendor, a Cisco vendor, a Mikrotik vendor, and right now if we talk about the highest certifications at this time, it's at Cisco.

This is one of the example of a working locker from Inbookinger, there will be several lockers later. The requirement is sometimes to prevent network verification, create configuration SD-WAN. This is a bit heavy, because SD-WAN is an advanced material.

There is also CCNA and CCNP at the minimum, friends, here. This is what I took there. Well, I got the information from several information, there are jobstreet, gleanse, and also LinkedIn here. Friends, you can check several network engineer lockers on several of these websites. Now if we check here, we try to find a network engineer.

there are still many related holes related to the network engine, Gateway, NUC, and so on, and there are still many for lockers from those in networking, friends, if you are interested, you can enter networking, okay, maybe that's friends, related to our introduction video, if you want to see the continuation, please continue to the next video later, okay, see you next video, friends
