COMBINING TECHNOLOGIES

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

LIST THE SIMILARITIES BETWEEN PHONES AND LAPTOPS?•Portable•compatible using USB cable•Wi-Fi•Camera•Multifunctional device: using the internet, emails 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.

NETWORK TRANSFERTHE 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•It is measured in bits per second (bps)•1 KBPS means 1000 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.

USER EXPERIENCE

•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.

YOU NEED TO EXPLAIN WHAT BANDWIDTH IS AND WHY IS IMPORTANT
