IT 223 - Exam 1 practice
Most modern computers are connected for some or all of the time to a _______________. - (correct
Answer) - network
Many networks are connected to _________________________________,
either directly or through intermediate networks. - (correct Answer) - "the" Internet (a global
internetwork)
LAN - (correct Answer) - local area network
A LAN may connected to another LAN/s
forming a campus [area] network, _____________ - (correct Answer) - wide-area network
(WAN),metropolitan area network (MAN), et cetera.
A _____________ is typically used to connect multiple LANs. - (correct Answer) - router
A router is often connected to the Internet
(via a modem at each end, not shown).
Effective communication can occur only if there is a____________________
between each communicating entity. - (correct Answer) - protocol
A protocol is an agreed convention for behavior in a specific context.
In modern networking the most common protocol suite is ___/___,
named for the most-used protocols in two of its levels: - (correct Answer) - TCP/IP
-Transmission Control Protocol
- Internet Protocol
The International Organization for Standardization (ISO)
has defined the Open Systems Interconnection (OSI) Reference Model:
- "open" - non-proprietary;
- "systems" - collections of entities;
- "interconnection" - connection between systems.
, It uses seven layers, each with different functionality,
to provide a theoretical foundation
for connecting software applications together. - (correct Answer) - 1. Application
2.Presentation
3. session
4. transport
5. network
6. data link
7. physical
TCP/IP SUITE
TCP/IP is an implementation of the concepts described in the OSI Reference Model - (correct Answer) -
Application
TCP
IP
DATA LINK
PHYSICAL
The _______________________ describes the mechanical connections
and the signaling technology of the networking equipment. - (correct Answer) - Physical layer
- A typical Physical layer connection today
might consist of Category 6 unshielded twisted-pair (UTP) insulated copper wires with RJ-45 plugs and
sockets. Bits are represented by specific voltage levels over wire pairs.
- The Physical layer describes tangible objects.
All the layers above it describe software and intangible data
The _________________ describes the representation of data
for the interconnection. - (correct Answer) - Data Link layer
- In the TCP/IP suite there are two sub-layers here.
