Zo werkt het bij ons ook ongeveer. Alleen ben je wat vrijer dat je niet elke les een test MOET afleggen. Je kan er ook een week later meer dan 1 doen of zo. In juni moet je ze wel alle 5 gedaan hebben om het eindexamen te mogen doen.

Op welke school zit je dan? is het een ROC mondriaan?
Ik heb pas een hardware/software cursus gedaan, Nu weet ik bijna alles wat er in de pctje gebeurt. Ik heb een Netwerk boek gekregen, De schrijver heeft CCIE en Juniper gedaan ( en dat zijn er maar 26 mensen op de hele wereld ) die boek leert je de basis van netwerken.

Layer 7 is the APPLICATION layer: provides services directly to applications. Responsible for identifying and establishing the availability of the intended partner, and required resources. It is also responsible for determining if there exist sufficient communication resources to reach the remote partner.
Layer 6 is the PRESENTATION layer: Data encryption, decryption, compression and decompression are functions of this layer. It does this by using Abstract Syntax Notation 1 (ASN.1) ASN.1 standardization allows differing computer architectures to exchange data that are from differing computer architectures.
Layer 5 is the SESSION layer: facilitates a dialog between communicating systems and controls the dialog. Offers three different dialogs, simplex, half-duplex and full duplex. Session is set up by connection establishment, data transfer and connection release.
Layer 4 is the TRANSPORT layer: Segments data and also reassembles data from upper layers. Delivers data in a connection and connection less modes. Includes simplex (one way) half duplex (both ways one at a time) full duplex (both ways simultaneously). Also flow control and error recovery.
Layer 3 is the NETWORK layer: Establishes a connection between two nodes by physical and logical addressing. Includes routing and relaying data through internetworks. This layer’s primary function is to deliver packets from the source network to the destination network.
Layer 2 is the DATA LINK layer: Ensures hardware addressing of the device, and delivery to the correct device. Translates data messages from upper layers to frames, enabling hardware to transmit upper layer messages as a bit stream. Provides flow control to the layer 2. Also carries a Frame Check Sequence to make sure the frame received is identical to the one transmitted.
Logical Link Control (LLC) Sublayer of the Data Link Control layer provides flexibility to Network Layer and the Media Access Control (MAC) layer. It runs between Network Layer and the MAC sublayer of the data Link Layer.
Media Access Control (MAC) Sub Layer of the Data Link Layer is responsible for framing. It builds frames from the 1s and 0s that the Physical Layer picks up from the wire.
Layer 1 is the PHYSICAL layer: Which transmits the raw bit stream and includes electrical signaling and hardware interface.

Dat noemen ze het OSI model (OSI was bedoeld als wetenschappelijk alternatief voor TCP/IP). Zelf heb ik wat gemengde gevoelens over al die certificaten. Ik heb zelf veel uit de praktijk geleerd en geen certificaten. Toen de cisco certfied (internet_) enigineer er niet uitkwam bij mij op het werk werd mij gevraagd het probleem op te lossen. Wat er exact was weet ik niet meer maar hij had iets basaals over het hoofd gezien *zucht* Sotry of my life

OSI Is gemaakt zodat netwerken met elkaar kunnen communiceren, Netwerken met verschillende hardware/software hadden moeilijkheden om te communiceren met andere netwerken.
Dus had de ISO de OSI ontworpen.
Denk dat je dat bedoelt?
