COMBINING TECHNOLOGIES

WHY COMBINED? Achieve a lot more by using them together Achieve a lot more by using them together

LIST THE SIMILARITIES BETWEEN PHONES AND LAPTOPS? Portable Portable compatible using USB cable compatible using USB cable Wi-Fi Wi-Fi Camera Camera Multifunctional device: using the internet, s and uploading images Multifunctional device: using the internet, s and uploading images

JACK IS TRAVELING THROUGH EUROPE AND WOULD LIKE TO UPLOAD IMAGES HE HAS TAKEN TO ONLINE ALBUMS. HE HAS A DIGITAL CAMERA, A MOBILE PHONE AND NETBOOK. A- LIST TWO WAYS IN WHICH HE COULD TRANSFER THE IMAGES FROM HIS CAMERA FROM HIS NETBOOK. B- JACK IS IN AN AREA WHERE THERE IS NO WI-FI SIGNAL. DESCRIBE HOW JACK COULD UPLOAD THE IMAGES FROM HIS NETBOOK.

BANDWIDTH AND LATENCY Are two measurements to describe the performance of a network connection. Are two measurements to describe the performance of a network connection. NETWORK TRANSFER THE SIGNALS ARE TRANSFERRED BETWEEN DEVICES IN BINARY (0 AND 1)

BANDWIDTH: MEASUREMENT OF CAPACITY Bandwidth is the number of bits that can go through the network connection in 1 per second Bandwidth is the number of bits that can go through the network connection in 1 per second It is measured in bits per second (bps) It is measured in bits per second (bps) 1 KBPS means 1000 bits every second 1 KBPS means 1000 bits every second 1MBPS means ……. Bits every second 1MBPS means ……. Bits every second

LATENCY: MEASUREMENTS OF DELAY Is the time in milliseconds between a bit leaving one device and arriving at the other. Is the time in milliseconds between a bit leaving one device and arriving at the other. PC1PC2

USER EXPERIENCE The best streaming and user experience such as playing games and watching YouTube is to have high bandwidth and low latency The best streaming and user experience such as playing games and watching YouTube is to have high bandwidth and low latency Downloading lots of files at once will slow down data transfer as the bandwidth being shared by each download. Downloading lots of files at once will slow down data transfer as the bandwidth being shared by each download.

YOU NEED TO EXPLAIN WHAT BANDWIDTH IS AND WHY IS IMPORTANT JADE WANTS TO WATCH BBC IPLAYER IN HD ON HIS COMPUTER. EXPLAIN WHY THE BANDWIDTH OF JADE’S INTERNET CONNECTION IS IMPORTANT.
