Network Architecture and Network Classification

Network Architecture

​Revise the notes on topic 2.2 and 2.3, then answer all the questions.

Multiple Choice

What is network Architecture?

• The layout of the computers and devices in a communications network

• The design of computers, devices, and media on a network to communicate with each other

• The physical location of all the device and communication devices on a network

• The shape of the network, either bus, star or ring.

Multiple Choice

What is the correct description/ definition for the type of architecture shown in the picture?

• Each computer has equal responsibilities and capabilities , sharing hardware(such as a printer), data and information with other computers.

• Each computer has equal rights to use the network, and anyone can force the other to be ban

• The computer are connected together in such a way that the network looks like a ring

• The computer in this type of architecture has the responsibility to make sure each computer can use the internet equally

Multiple Choice

What is the function of the server?

• 1. Controls access to hardware on the network

  2. Controls which device can connect to the network

  3. Providing a central, common file storage area

• 1. takes oerders fronm other computers

  2. Serve the other computers with funds

  3. Managing the voltage used by the network

• 1. Act as the master for all the other pc on the network

  2. Controls whether other pc can be turn on or not.

  3. Solve every problem that is typed in the client pc

Multiple Choice

Which of the following is an advantage of a client-server network?

• Files and folders cannot be centrally backed up.

• Does not need an expensive server as individual workstations are used to access files.

• The server is expensive to purchase

• Files are stored in a centralised location, meaning it is easier to backup.

Multiple Choice

Which of the following is an advantage of a peer to peer network?

• If one computer fails it will not disrupt the network.

• There is little or no security.

• Users can access shared data which is centrally controlled.

• If any part of the network fails, a lot of disruption can occur.

Multiple Choice

Is The Statement below TRUE or FALSE "Compare to Peer to Peer architecture, Client/ Server architecture is cheaper"

• TRUE

• FALSE

Multiple Choice

Is The Statement below TRUE or FALSE "You need network professional to manage peer to peer architecture."

• TRUE

• FALSE

Multiple Choice

Is The Statement below TRUE or FALSE "The minimum number of devices on a peer to peer network is 2."

• TRUE

• FALSE

Multiple Choice

Is The Statement below TRUE or FALSE "in a Client/ server architecture, all devices or PC has equal responsibility."

• TRUE

• FALSE

Multiple Choice

Which one of these items is true of a peer-to-peer network?

• No network wide security in place

• Central control of security

• Has a central point of failure

• Easier to perform network wide backups

Multiple Choice

Which is a disadvantages of a client-server network?

• When server isn't on, clients don't power up

• Clients can't connect wirelessly to the server

• Dependent on server - if it goes down, clients stop working

• Clients are more expensive than servers

​2.3 Network Classification

Multiple Choice

A LAN can be used to connect a country?

• True
• False

Multiple Select

The main differentiation among LAN and WAN are

• setting up cost

• network size

• transmitting speed

• connection limit of computer

Fill in the Blanks

Multiple Choice

Identify the classification of network based on the following explanation: A network that covers a large geographic area, such as a city or country using a communication channel that combines many types of media.

• Local area network (LAN)

• Wide area network (WAN)

Fill in the Blanks

Multiple Select

______ & ______ are the examples of Local Area Network (LAN).

• Home network

• Office building

• Internet

Multiple Choice

Which one of the following is the example of Wide Area Network (WAN)?

• Cable TV Network

• University Campus

• Internet

• Bluetooth Devices

Multiple Choice

What is a characteristic of a LAN?

• Uses less cables than WAN

• Really cheap to set up the network

• covers limited geographical location

Multiple Choice

A cabled network used in one building.

• WAN

• WLAN

• LAN

Multiple Choice

Several networks connected together using a router.

• WAN

• WLAN

• LAN

Multiple Choice

A wireless headset could be part of a network

• True
• False

Multiple Choice

Who owns the infrastructure of a LAN?

• External organisation that charge users rental

• The organisation using the LAN

• The government

• A BT customer

Multiple Select

What are the three characteristics of WAN

• Lower bandwidth compared to LANs

• Typically interconnects multiple LANs

• Requires user name and password

• Exist in unlimited geographic area

Multiple Choice

What is an advantage of a LAN?

• You can share peripherals like printers.

• It is more secure than a standalone computer

• Data and information cannot be easily shared

• Expensive to setup.

Multiple Choice

What is an advantage of a WAN?

• Viruses can spread to other computers throughout a computer network.
• Managing a large network is complicated, requires training and a network manager usually needs to be employed.
• Can cover near infinite geographical distance
• Easy to install and maintain.

Multiple Choice

What is a disadvantage of a WAN?

• Due to it's typically massive size, WAN's are almost always slower then a LAN. The further the distance, the slower the network. 
• Limited to a small area.
• Data is easy to backup as all the data is stored on the file server.
• Site (software) licences are likely to be cheaper than buying several standalone licences.
