Lesson Objectives 0 By the ened of the class you should be able to: 0 Compare the three kinds of primary storage devices. 0 Determine in which situations each primary storage device is better. 0 Identify secondary storage devices.

Primary Storage Devices By Omar Alvarez Badillo Roc Boronat

Selecting the best computer TraitsPart to compare 1. We don’t want a slow computer 2. We want to OPEN many programs same time. 3. Turn on FAST and be able to SAVE all my MUSIC 0 Microprocessor 0 Cores 0 Clock Speed 0 RAM 0 Size 0 Storage Capacity

What storage devices you know 0 Individually (2 min): List of all storage devices you know. 0 Share it with the person next to you. (1 min)

Teams 0 In groups, generate a list of all of them an group them into TWO categories. (3 min) 0 T1: 0 T2: 0 T3: 0 T4:

Primary Storage Devices 0 Fixed to computer 0 Can be replaced and upgraded in Laptops, Desktops and All-in-one 0 Determines the total storage capacity of the computer. 0 Responsable of how fast your computer turns on.

Hard Disk Drive 0 Conventional Primary Storage Device 0 The one that has the most capacity. 0 Cheapest $/GB  1GB = $1.5

Solid State Drives 0 Found mainly in Tablets, Smartphones and Ultrabooks 0 Fastest Boot time 0 Smaller storage capacities, < 256 GB 0 Most expensive 0 1GB  $10.0

Solid State Hybrid Drive 0 Found in some new ultrabooks, laptops, desktops and all-in-one. 0 Bost of best worlds, faster boot and big storage capacity. 0 Average Price: 1GB ->$2.5 0 Two sizes: HDD and SSD 0 1TB + 64GB

Which one to buy? 0 Individually (3min): Determine in which type of situation each type of primary storage device is best. 0 In pairs (2 min): Compare your situations and discuss if any of them may disappear in years to come.

Next time I buy a computer… 0 Individually (3min): Answer in one sentence the following question. 0 Next time you buy a laptop, which kind of primary storage device will you look for and why?.
