In the early history of computing, before the personal computer, which model of networking was most commonly used?
Which term is defined as the communication delay caused by sending delays between two computers?
In a two-tier client/server computing model, which of the following tasks does the client perform?
Requests and displays data.
Amanda is designing part of a network using a three-tier client/server computing model. She is responsible for the second tier of the network. What task does the second tier perform?
First tier: Client. Responsible for formatting data and display.
Second tier: Requests the data.
Third tier: Server. Retrieves the data.
The software application usually running on the end user's host can be called which of the following?
Client. Term can refer to the computer that is accessing a server, or the software application on that computer.
What type of network can connect customers and vendors to the internal networks of a business?
Extranet. Allows secure access by external parties to an internal business network.
In web-based networks, the web browser provides what function?
Client. Sometimes called the universal client because it's an application for viewing many different types of data.
What best describes a peer-to-peer network?
This network can connect as few as two computers. P2P networks are not recommended for connecting more than 10 computers.
Which of the following applies to ring and bus networks?
a. Cabling is easier than on star networks.
b. If one node fails, the entire network can fail.
c. These networks handle heavy traffic well.
d. Network management is centralized.
B. If one node fails, the entire network can fail. A token ring network without a MAU and a bus network can fail if a single node isn't operating. Cabling a ring network can be more diff than a star network if a central MAU isn't used.Bus networks handle heavy traffic poorly, while ring networks do well. Bus networks lack a server, so network management is decentralized.
Brad is installing a star network. Which one of the following pieces of hardware will he need to install?
A. Server
B. Terminator
C. Multistation access unit
D. Hub
D. Hub. Brad will need to use a hub as a concentration point to tie all the computers in his star network together.
Stars don't require servers. Terminators are for bus networks; MAUs are used on ring networks.
Which type of network topology can use a Multistation Access Unit (MAU)?
Ring. MAU is used in a ring network to keep the network running in case one node fails.
Which network can span the greatest distance without the use of additional networking hardware?
Ring. The ring topology can span the greatest distance because each node amplifies the signal that is sent to the next computer.
Without a specific design, we can't say
the hybrid would work best.
Bus networks work best at short distances.
Mesh networks use a great deal of cable to interconnect nodes, which can also
limit signal distance.
What is the name of the feature that allows all NOS to work with each other?
A. Transparency
B. Interoperability
C. Scalability
D. Latency
B. Interoperability refers to a general
set of features and services that
help define a NOS.
Transparency is an attribute of an image file.
Scalability refers to a system's ability to handle larger amounts of data.
Latency is the delay of time between two computers.
Which one of the following types of networks does not require dedicated servers?
A. Enterprise
B. Server based
C. Peer-to-peer
D. NetWare
C Peer-to-peer. Server-based networks must have at least one server.
Enterprise networks combine peer-to-peer and server-based networks, so there must be a server. Novell NetWare
uses a server for network file storage.
No server is required in a peer-to-peer network.
A network operating system most closely resembles which of the following network models?
A. Mainframe
B. Client/server
D. Enterprise
B. NOSs work on a client/server model
Which of the following is the best description of the backbone of a computer network?
A. The backbone is the level at which smaller networks are typically connected.
B. The backbone connects computers on a peer-to-peer network.
C. The backbone is the device that connects computers in a star network.
D. The backbone is the device that connects computers in a ring network.
A backbone is the highest level in the computer network hierarchy. It typically connects two or more smaller networks together.
Cables or another transmission medium connects P2P computers.
Hubs connect computers on a star network.
A MAU can be used to connect computers on a ring network.
Which of the following NOSs is used most often on internet servers?
A. Microsoft windows
B. Novell NetWare
C. Mainframe operating systems
The Linux OS is derived from which earlier operating system?
A. Microsoft Windows
B. Novell NetWare
C. Mainframe operating systems
Microsoft windows and Novell NetWare were developed separately from Linux.
