1. In terms of physical-level, security for stand-alone PC: 1.1 It is more secure than networked one 1.2 Has the same level of security as networked PC; 1.3 Depends on the protocols used in the network:; 1.4 Depends on the size of the PC memory. 2 What is NOT true: 2.1 Traditional Wide Area Networks (WAN) has more nodes than Local Area Networks LAN); 2.2 Traditional LANs are faster than WANs; 2.3 Traditional WANs are faster than LANs 2.4 Traditional LANs and WANs use different communication technologies 3 The client-server communication based on: 3.1 The request-reply model; 3.2 Ability of the network to send data with very high speed; 3.3 Ability of the client machine to display graphical information; 3.4 Ability of the client machine to save a lot of data on its hard drive. 4. In the OSI Communication model Horizontal communication is the communication between: 4.1 Similar layers in both of communication parties; 4.2 Two layers on the same network node; 4.3. Any communication between client and server 4.4 Any communication between two clients. 5. During the communication between two parties the information always goes through the process called: 5.1 Compilation-decompilation; 5.2 Calculation-decalculation; 5.3 Compression- decompression; 5.4 Encapsulation-decapsulation. 6. Which protocol provides connection-oriented communication? 6.1 UDP: 6.2 IP 6.3.ICMP; 6.4-TCP. 7. Which protocol intended to provide better reliability? 7.1 Connection-oriented; 7.2 Connectionless; 7.3 Both have the same level of reliability 7.4 Depends on the type of the data transmitted; 8. If a message is too long to be sent through the Internet as is, it will be: 8.1 Truncated; 8.2. Fragmented; 8.3 Rejected; 8.4 Sent back to the source node
