Network Hardware
What does WAP stand for?
Wireless Access Point
In packet switching method, do all the packets reach in same order?
No
Name two types of network cables.
Fiber Optic
Twisted copper
Name three types of network connection.
- Wired
- Wireless
- Mobile data
Define digital data.
Data stored in a computer
A --------------- is necessary in a network construction if we are using copper cables and network devices are more than 100 meters away from the main server room
Hub room
Name three pieces of information that are included in a packet when it is sent over the internet.
1- The recipient address.
2-The sequence of the packets
3- The total number of packets
Network cables that connect nodes and send data through light signals. These are transfer data faster than the other type of cables but cost more.
Fiber Optic
What is the information you need to enter to access your home network?
- Network name
- Network security key for the router
How digital data are stored in a computer?
As binary system (0 and 1)
Write down two major differences between a hub and a switch.
1- A hub sends the message to everyone in the network while the switch only sends the data to the person it meant to.
2- Switch is more difficult to set up and more expensive while the hub is easier to set up and cheaper.
Why the router sends each packet to different servers?
To help finding the best and less traffic route to send the packet to the receiver.
A ------------- is used to convert data pass along network cables to digital data.
What is a hotspot?
A place where you can connect to a wireless network in public places (WAP)
What is the difference between data and information?
On its own data may not mean much but if we format, sort and analyze data will have more meaningful results (information).
What does a server do?
A server serves' files to users and devices (such as printers) in a network. For example, when a user wants to open a file stored on the network, it is the server that finds the file and sends it to the user's computer.
Why are internet messages sent as packets?
Because small packets are easier to be handled by the network hardware devices and if a packet gets lost it is easier to resend that specific packet only
What NIC stands for?
Network Interface Card
Give me one advantage for wireless network connection over the wired connection.
What are the factors that can get your wireless connection to be weak.
Allows you to connect to the network even if you are not near to the network socket.
Signals can become weak if it faced a wall or physical bulky items in its way.
List two main roles of a router
- Connects a device or LAN to the internet
- Choose the best route for any packet when sent over the internet
Define packet switching method in your own words
- A file will be broken into small packets of data
-each packet takes its own route over the internet
- the receiving computer checks that it has all the packets
- When all packets received, they put again in correct order
- The file is now ready to be opened and read
what are the troubleshooting steps we need to follow if we can not get connected to our home network. Name two at least
- Check the username and password (password is case sensitive).
- Wifi might be off on your device
- The router has loose or disconnected cable
- The electrical power to the router is turned off
- The router need rebooting
