OSI Model Exam Questions With Correct
Answers
OSI |Model |- |CORRECT |ANSWER✔✔-model |for |understanding |and |developing |computer-to-
computer |communication; |divides |networking |functions |among |7 |layers
| Application, |Presentation, |Session, |Transport, |Network, |Data |Link, |Physical
TCP/IP |- |CORRECT |ANSWER✔✔-Transmission |Control |Protocol/Internet |Protocol. |Protocol |that |
connects |computers |to |the |Internet. |Tells |computers |how |to |exchange |information |over |the |
Internet.
Application |Layer |- |CORRECT |ANSWER✔✔-Layer |7 |of |the |OSI |model. |The |network |layer |that |
houses |the |applications |that |allow |users |to |access |the |network. |It |contains |five |categories |of |
services, |File |services, |e-mail |services |, |network |printing |services, |Application |services |and |
database |services.
Presentation |Layer |- |CORRECT |ANSWER✔✔-The |sixth |layer |of |the |OSI |model. |Protocols |in |the |
Presentation |layer |translate |between |the |application |and |the |network. |Here, |data |are |
formatted |in |a |schema |that |the |network |can |understand, |with |the |format |varying |according |to
|the |type |of |network |used. |The |presentation |layer |also |manages |data |encryption |and |
decryption, |such |as |the |scrambling |of |system |passwords.
Session |Layer |- |CORRECT |ANSWER✔✔-The |fifth |layer |in |the |OSI |model. |The |Session |layer |
establishes |and |maintains |communication |between |two |nodes |on |the |network. |It |can |be |
considered |the |"traffic |cop" |for |network |communications.
Transport |Layer |- |CORRECT |ANSWER✔✔-4th |layer; |protocols |ensure |that |data |are |transferred |
from |point |A |to |point |B |reliably |and |without |errors; |services |include |flow |control, |
acknowledgment, |error |correction, |segmentation, |reassembly, |and |sequencing
