For anyone trying not to read the book I think it's important to point this out. The top, or seventh, layer of the OSI model is the Application layer. Contrary to what its name implies, the Application layer does not include software programs, such as Microsoft Word or Firefox. Instead, the Application layer facilitates communication between such programs and lower-layer network services. A better example would be the HTTP protocol which sends your request from the client's browser to the server. The presentation layer being explained as " The OS " is not satisfactory in any way. The presentation layer is better thought of as an interpretation between computers for sending images or video. Video compression like divx fall into this layer. The presentation layer interprets content transmitted within the HTTP response from the application layer.

Actually the Transport Layer (layer 4) is where TCP and UDP protocols live. It's very important and involves whether connections even need to be established/terminated and whether data arrives in sequence or is error checked (CRC checksums). Also, from a more pure communications perspective, encryption/decryption happens at the Presentation Layer (Layer 6). So layer 6 is a much broader concept than an OS on a corporate laptop.

In the Network+ Guide to Networks Sixth Edition it is explicitly stated that the application layer does not include software programs such as Microsoft Word or Firefox (pg. 44 Ch. 2). Rather it contains protocols that interact with such programs. For example HTTP.
@MrLFXproductions9 жыл бұрын
xSpArTiChRiSx I'm literally still learning all this but my teacher explained the application as only containing applications that are network aware. So for example an application that works as normal once you've unplugged your ethernet cable (or disabled wifi) is not in this layer. I'm still learning it all though...
@xSpArTiChRiSx9 жыл бұрын
MrLFXproductions The explanation your teacher gave you is brutally basic and very subjective. This explanation would suffice if you where going for a programing degree and he just needed to touch on the OSI model for a brief understanding. However if you are going to be in the IT field (net admin etc) then I would be a little upset with your instructor. As stated before, the Application Layer should not be confused with the "apps" that a user may interact with but rather the protocols that interact with the"apps". For example, BitTorrent is a program that shares the same name as the protocol it uses to facilitate peer to peer file sharing. The protocol BitTorrent would go in the Application Layer. However the program BitTorrent would not be on the OSI table at all. A good way to understand this is to think of the OSI model as an onion. You (the user) may pick up the onion and look at it and smell it. This part of the onion is the GUI of the OS and the programs. You peel away that part of the onion and you will see the protocols. So on and so forth.
@skyking32109 жыл бұрын
xSpArTiChRiSx Yeah any program that is network aware (can store, send, and retrieve data over a network) is described as a Layer 7 application (differentiating them from non-network aware apps). These programs are not to be confused as residing in the respective layer. Layer 7 apps utilise (tap into/connect with) the protocols that are associated with this layer, e.g, FTP, SMTP, POP3, NTP, SNMP and TFTP. Thanks for the clarification.
@korisx9 жыл бұрын
Sky King This just makes sense as the OSI is specific to networking. In saying that I would have stopped at Apps that have access to the network and not looked at the protocols as xspArTiChRisx has described, so thanks to him for that clarification. I wish I could study full time instead of working full time and having to learn my modules within days of my assignment due dates.

I work 6 days a week with Friday being my only day off and I was taking two networking classes that where held Mon-Thurs. Towards the end of the semester we had a big test on subnetting and I just couldn't do it. I didn't know the material at all because I didn't have the time to understand it. The OSI model, RAID, and converting IP to Binary and Hexadecimal where all things I learned like 30mins before class. I tried to do that with subnetting and failed miserably and had to drop the class.

Software and Network Engineer here! The Application Layer is (to use a development term) an abstraction layer. An abstraction layer hides the intricacies of the lower layers from "applications". It provides a set of rules (Application Program Interface) for accessing services from the lower layers.
@SteveInFrmnt11 жыл бұрын
Hi Eli, I totally agree with your view that: "... understanding the way modern networks are implemented based on a layered approach that follows the OSI model is very helpful." and "....understanding the key functions and services at each layer helps design, manage and trouble shoot issues" is a solid approach to diagnosing problems/trouble shooting network issues. But I do take issue with how you represented some of the functions and services and also disagree with your statement that an IT - networking persons do not deal with the functions of layers 4 through 6 in operating, designing and diagnosing networks. Some of my observations below and please take my comments as additional information not criticism. Steve Arnold Fellow network architect, engineer and educator ------------------------------------------------------------------------------------------------------------------------- Application Layer is not where application programs are - this layer expose protocols (rule sets) as a set of APIs and services that are used by applications and operating system to interaction across a network. For example your web browser may be working perfectly - but not able to find servers on the internet by name. No amount of exiting/starting Firefox is going to fix it, because the DNS service or host name table is corrupt - which IS a layer 7 exposed service and may require stopping and starting the DNS service. Presentation Layer in general normalizes data (symbols, syntax, semantics) representation between programs/devices that are not the same. Such as a computer with an ASCII symbol set interacting with a computer with an EBCDIC symbols. For example you are doing file transfers between computers and the data is being corrupted because the presentation layer which has an ASCII symbol table does not have the proper extension symbols loaded. Session Layer deals with application oriented event sequences and synchronization. For example think about a program opening a file and reading data needs to synchronize these events with a file server that is actually controlling the file system across a network. It is also where single/multi-threading of program to program sessions is managed and you did cover one of the key issues which is the number of allowable sessions for a server, though there are other key network issues such as database locks that do not clear or remote procedures that hang which manifest at this layer. These days the above 3 layers are typically implemented as Application Protocols as vetted and published by the IETF (Internet Standards Group) and are melded into a single "uber-layer". Examples such as HTTP, SMTP, NNTP, and so on. BUT they are not application programs. They are services invoked by application programs such as Firefox, Outlook, News Readers and so on. Yes layer 4 - transport deals with size and flow (windowing), but I believe you missed covering some major elements of transport around QOS quality of service, MTU - maximum transmission unit size, ports - especially well known port numbers used for firewall, security and some tunneling activities. All of which are key networking items. And layer 4 will continue to grow in network operation/design/trouble shooting as more voice and video traffic moves to using the OSI/IETF model for communications. I have not watched your ARP video yet - but hope it makes the connection - no pun intended between resolving the layer 2 addresses with the layer 3 addresses and I typically see this as a layer 3 networking issue not a layer 2 issue as you state. Given I can run a layer 2 physical network without the need for ARP (i.e. NETBIOS networks) but the inverse is not true for a layer 3 - IPv4 network. Last heartburn is on the statement that the physical layer is the "wiring". I get where you are coming from in that the physical environment is many times manifested as problems/symptoms in layer 1. The physical layer is the attachment point for the device/appliance to encode/decode information into/from the media. And that media can be wire as you state but is also very much wireless these days. BUT the physical layer along with the link layer is much more than that. It deals with things like sharing the media - which has major performance implications. Connection management which is key to things like pairing, access point issues and mobility such as with smartphones. And baseband/broadband/multiplexing and compression functions which again are in the physical layer not the wire and do need to be addressed as an IT/networking person. additional references; en.wikipedia.org/wiki/OSI_model www.escotal.com/osilayer.html www.texbuddy.com/OSI.htm (note they use generic terms for protocols in layer 7 - not to be confused as application programs them self)

Thank you for this video. I recently graduated from an EE program and this was such a better presentation to make a correlation between the technical vernacular the ACTUAL way things work. Your videos are invaluable and I can’t thank you enough for taking the time to make these videos as I’d imagine they are very time consuming.

Eli, I would like to thank you so much for the many presentations put together free for our learning, "Incredible". It inspired me to start getting IT classes. This is what i term professionalism. The tone of voice is truly a mastery of the art of public speaking.The type of voice one will not get tired of listening to. Well Done
