Module 2.2: network basics Flashcards
What is a Personal Area Network (PAN)?
Organised around individuals within a range of a few metres; usually one computing device pairs with one or more other devices
Main purpose is to automate connections between mobile devices
What are the main advantages of a Personal Area Network (PAN)?
Automates connections between mobile devices
Facilitates easy communication between personal devices
What are the disadvantages of a Personal Area Network (PAN)?
Range of a few metres; data transmission can be slow; peripheral devices usually paired with only one computing device at a time
Limits the usability and speed of data transfer
Define Home Area Network (HAN).
Network within a home environment; uses wired or wireless connection methods
Can enhance connectivity among various household devices
What is a significant security concern when setting up a wireless Home Area Network (HAN)?
Security can be an issue; must address with passwords etc.
Ensuring proper security measures is crucial to protect the network
What hardware is needed to set up a Home Area Network (HAN)?
- Switch
- Router
Switch connects computers; router allows internet connectivity and sharing
What is the role of a switch in a Home Area Network (HAN)?
Used to connect computers in a HAN (but not for internet access)
Facilitates communication between devices within the network
What is the function of a router in a Home Area Network (HAN)?
Allows computers to connect to networks like the internet; built-in switch allows other devices in HAN to ‘talk’ to each other and share internet connection
Essential for internet access and device communication
What connection methods are typically used in a Personal Area Network (PAN)?
Usually Bluetooth
Enables short-range wireless communication between devices
What connection methods are typically used in a Home Area Network (HAN)?
- Wired connections
- Wireless connections
Variety of methods enhances flexibility in device connectivity
What is required for wired connections in a Home Area Network (HAN)?
Every network device must have a NIC (Network Interface Controller); connects to the switch/router via UTP cable (Unshielded Twisted Pair)
NIC is essential for network connectivity
What is required for wireless connections in a Home Area Network (HAN)?
Every network device must have a built-in wireless adaptor; use WiFi feature of router
Adaptors facilitate wireless communication
What is the definition of the Internet?
Worldwide computer network consisting of computers and networks linked by wired and wireless communication media
Connects millions of private, public, academic, business, and government networks
What is an IP (Internet Protocol) address?
Every device connecting to the internet must have its own
Unique identifier for each device on a network
What is the role of an Internet Service Provider (ISP)?
Company with a permanent, fast connection to the internet; they sell internet access and services for a monthly fee
Examples include companies like MWEB
