TMA Questions and Answers on CIT 722 (Computer Networks) Part 2.

1 The way a network is laid out either physically or logically is ---

• network diagram
• network topology
• network schema
• network state

2 There are --- basic topologies

• two
• three
• four
• five

3 One of the advantages of star topology is

• Requires more cable length than a linear topology
• If the hub or concentrator fails nodes attached are disabled
• More expensive than linear bus topologies because of the cost of the concentrators
• Easy to install and wire

4 The important part of the network design theory is ---

• knowledge
• accuracy
• topologies
• adequacy

5 … is a topology

• List
• Map
• Mesh
• Bi-map

6 Network protocol is

• a set of semantics that governs the communications between computers on a network
• a set of rules that governs the communications between computers on a network
• a set of syntax that governs the communications between computers on a network
• a set of rules that governs the definitions between computers on a network

7 Syntax ---

• refers to the structure or format of the data
• refers to the meaning of the data
• refers to the semantics of the data
• refers to the meaning of the network

8 Semantics of the protocol ---

• refers to the format of data
• refers to structure of data
• refers to layout of data
• refers to the meaning of each section of bits

9 The key elements of a protocol are syntax, semantics and

• clock
• timing
• speed
• accuracy

10 Protocol stacks are ---

• the combination of the different protocols
• the connection of the different protocols
• the arrangement of the different protocols
• the stacking of the different protocols

11 … computer plays a centralized role in a client/server model

• Server
• Client
• Master
• Slave

12 What do we call the computers that don't play centralized role in a client/server model?

• Clients
• Slaves
• Auxilliaries
• Tempos

13 In a peer to peer network all computers acts as a

• server
• client
• master
• member

14 SMTP ---

• is a protocol
• is a protocol that is used to send the email messages between the servers
• is a protocol that is used to send the email messages

16 … is the interference between two signals s

• Jam
• Jamming
• Collision
• Confusion

17 … is a well-known and widely used network technology that employs bus topology

• IP
• Ethernet
• Bus
• Token

18 All computers attached to an Ethernet participate in a distributed coordination scheme called

• CSAM
• CSMA
• SAMC
• CAMS

19 SNMP is used for

• managing the network attached devices of the complex network
• managing the devices
• managing the devices of only client/server
• all of the options

20 FDDI stands for
