Principles of Network Architecture

What is network Architecture?

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

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

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

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

What type of network architecture is shown in the picture?

• Client/ Server
• Peer to peer
• Server/ customer
• Stand Alone network

Which best describes a server?

• A computer that stores data
• A computer that stores software
• Central computer - provides clients with functionality
• A computer within a network

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 orders from 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

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.

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

• TRUE
• FALSE

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

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

Rapid app development can be designed by application developer because ...

• network core devices only function at lower layers.

• programming language is getting easier.

• programs run on the same end system.

• program runs within a network.

The following statements describe about sockets EXCEPT:

• It is also referred to as the Application Programming Interface (API) between the application and the network.

• App developer only can control choice of transport protocol and able to fix a few parameters such as maximum buffer on the transport-layer side of the sockets.

• The application developer has no control on the application-layer side of the socket

• It is a software where process sends messages into, and received messages from, the network.
