Connectivity & Connection Types Flashcards
Wired & wireless connections
What are the 3 wired device connections
VGA
HDMI
USB/FireWire
What are the uses of VGA & its advantages/limitations
(Wired device connections)
Uses
Analogue connection of video display equipment, such as TV’S
Advantages
- Universally used on high resolution display equipment
- Low cost cabling
Limitations
- Cumbersome cabling
- Signal affected over distance (noise)
- No digital rights managements
What are the uses of HDMI & its advantages/limitations
(Wired device connections)
Uses
Digital connection of both video & sound from devices to display equipment
Advantages
- Capable of 8k + beyond resolution
- Used in computing & entertainment
Limitations
- Limited length
- Cabling & technology is more expensive than analogue equivalents such as VGA
What are the uses of USB/FireWire & its advantages/limitations
(Wired device connections)
Uses
Connecting equipment & peripherals, such as printers, scanners, input devices, cameras
Advantages
- High speed capability
- Backwards compatibility
- Can connect multiple devices
Limitations
- Limited distance
- Limited power supply
What are the uses of Bluetooth & its advantages/limitations
(Wireless connection method)
Uses
For pairing devices over short distances & often used to connect mice & keyboards as well as audio devices such as headphones
Advantages
- Easy to setup
- Low power consumption
Limitations
- Low data transfer
- Very short range
What are the uses of WiFi & its advantages/limitations
(Wireless system connection methods)
Uses
To connect devices wirelessly to local & wide area networks such as the internet
Advantages
- High speed data transfer speeds
- Good range
- Relatively cheap to install
Limitations
- Can be complex
- Security concerns
What are the uses of 3G/4G/WiMAX & its advantages/limitations
(Wireless system connection methods)
Uses
To connect to data networks such as the internet whilst on the move
Advantages
- Allows true mobility
- 4G provides for very fast connection speeds
Limitations
- - Heavy data usage can be costly
- Uses public networks
What are the uses of s
satellite broadband & its advantages/limitations
(Wireless system connection methods)
Uses
Provides connectivity to remote areas, often rural
Advantages
- Wide coverage
- High speed
Limitations
- High latency
- Subject to weather conditions
What are the uses of Microwave/laser & its advantages/limitations
(Wireless system connection methods
Uses
Allows point to point LAN connection between locations
Advantages
- High speed
- No ongoing costs
Limitations
- Affected by poor weather
- High initial cost
What are the uses of WiFi Direct & its advantages/limitations
(Wireless connection methods)
Uses
For connecting devices to remote displays
Advantages
- Can transmit both audio & video
- Usually built in to devices
Limitations
- Limited range
- Can affect data connectivity
What are the uses of WiFi & its advantages/limitations
(Wireless connection methods)
Uses
Allows ‘ad-hoc’ networks to permit wireless printing/scanning, for example
Advantages
- Simple setup
- Uses existing WiFi infrastructure
Limitations
- Using ad-hoc networks can input connectivity
What are the uses of fibre optic & its advantages/limitations
(Wired system connection methods)
Uses
Telephone & internet cables, cable television & computer networking
Advantages
- Improved security as the cable cant be tapped
- Can be used over long distances
- High data transfer rate
Limitations
- Very expensive
- Specialist skills needed to install
What are the uses of Coaxial & its advantages/limitations
(Wired system connection methods)
Uses
All types of data communication, commonly used in television cabling
Advantages
- Less open to interference than UTP/STP so works over longer distances
- Cheap, though not as cheap as UTP/STP
Limitations
- Very expensive
- Specialist skills needed to install
What are the uses of Cat5 & its advantages/limitations
(Wired system connection methods)
Uses
Telephone communications & ethernet networks
Advantages
- Versatile & widely available
- Cheap compared to other networking options
Limitations
- Only useful over shorter distances
- More open to interference than other weird techniques such as fibre
What are the 3 wired system connection methods
