HDMI
USB/FireWire
What are the uses of VGA & its advantages/limitations
(Wired device connections)
Uses
Analogue connection of output video devices, 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
Transmission of audio & video signals between devices using cables
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 mice, keyboards & input devices
Advantages
- Fast data transfer speed
- Provides power to devices
- 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
Cat5
Coaxial
Fibre optic
What is connectivity
The ability to process digital data by connecting the operating system with applications & system & with each other
What are wired connection methods
Any method that uses physical cables to connect between devices, system or components
What are wireless connection methods
Connection that uses the electromagnetic spectrum. This may be traditional radio waves or light waves
