Yes, multiple postal workers and carriers handle and route the letter
No, the sender places the letter and it goes straight to the recipient
Only the sender’s computer is involved
Only the recipient is involved

The recipient’s email address
The recipient’s street address only
The sender’s printer model
The recipient’s shoe size
A message to Australia (part 2). Imagine that you needed to send a message from the UK to Australia and computer networks do exist. Would anyone be involved in relaying the message?
Yes, mail servers forward the message across networks
No, the message travels directly from sender to recipient with no stops
Only the sender and recipient computers connected by a single wire
Only the home router briefly stores the message and then it arrives
Message transmission: letters. An answer to the first scenario (no computer networks) might have been to write and post a letter. How is a letter sent from the UK to Australia? Which description best matches the steps involved between putting the letter in the postbox and it arriving at the destination?
It is collected, sorted through postal hubs, transported by air or sea to Australia, sorted again locally, and delivered to the recipient
It teleports instantly to the recipient’s house
It is converted into an email and sent through the internet
It waits in the postbox until the recipient retrieves it
Message transmission: letters. After dropping a letter in a UK postbox for Australia, what is the first place it typically goes?
A local sorting office
The recipient’s house
An email server
A school classroom
Message transmission: email. Just as a letter does not go directly from the sender to the recipient, the email does not travel directly to the recipient’s machine. Which statement about email transmission is true?
An email is relayed by many mail servers along the way to its destination
An email travels in one step directly through a single cable to the recipient’s computer
An email stays only on the sender’s machine until the recipient checks it locally
An email must be printed and physically mailed to arrive
Message transmission: email. Which component helps get an email message to its destination as it travels across networks?
Mail servers
Printers
Cameras
USB flash drives
All methods of communication need rules to pass on a message successfully. What term describes these sets of rules used in communication?
Algorithms
Protocols
Passwords
Hardware
According to the idea of protocols in communication, which is a common protocol for meeting someone new?
A handshake
Turning away silently
Shouting from a distance
Ignoring the person
Thinking about meeting someone new, are these protocols the same in all countries?
Yes, they are identical everywhere
No, they vary by culture and country
Only European countries share the same protocol
They are the same online but different in person
What rules (protocols) exist for an email address? Select all that apply.
It must contain an @ symbol
The email address must be unique
It must start with www
It must include http://
Consider the web address http://www.bbc.co.uk. Which parts show rules (protocols) being used? Select all that apply.
Website addresses start with http:// followed by www
All website addresses are unique
Dots are used to separate each part of the address
Email addresses must include an @ symbol
Network cables have plastic plugs that connect into sockets on devices, are made up of copper wires inside, and can send data in both directions. When spotting one in the classroom, which visible feature most clearly identifies it as a network cable?
A plastic plug on the end that fits into a device socket
A wooden casing with no connectors
A rubber band wrapped around the end
A paper label taped to the cord
A small company has 4 computers. All computers need to be networked together using cables so they can communicate and access each other’s files. What must be true about the cable connections?
Each computer must be connected with cables to the others so they are all part of the same network
Only two computers need cables; the others can stay disconnected
Computers only need power cables, not network cables
No cables are required because computers can communicate without any connections
The illustration shows every computer directly connected to every other computer with cables. What is the main disadvantage of this setup?
It requires many cables and becomes difficult to manage as more computers are added
It guarantees faster performance for every task
It prevents any computer from failing
It removes the need for any networking hardware
Using the pattern shown (4 computers → 6 connections, 5 computers → 10 connections, 6 computers → 15 connections), how many direct cable connections would there be with 20 computers if every computer is connected to every other one?
190
200
180
20

0
1
2
3
What is a server?
A powerful computer which provides services
A small program that runs in a web browser
A wireless signal booster
A type of network cable
What is the role of a file server on a network?
Store files in a central location so all devices on the network can access them
Route internet traffic between different networks
Display images on monitors
Provide backup electrical power to computers
Which kinds of files can a file server store for access by all devices on the network?
Text files
Images
Sound
Video
Imagine that computer A is turned off. Can computer C access files that are stored on computer A?
Yes
No
Build a network: scenario 3. The company wishes to install a device so that all 4 computers can store their files in a central location. Which device should be added to the hub?
