10 Types of storage أنواع التخزين Hard disk C a c h e

11 Programs كيفية التخزين Documents Photos

12 كيفية التخزين Binary Digit = Bit The smallest unit of storage on a computer Either 0 or 1 8 bits = 1 byte

13 Question: how much information can we store in a byte? Let s take a look at 4 bits (half a byte): How many values can we store?

14 Question: how much information can we store in a byte? Let s take a look at 4 bits (half a byte): How many values can we store? 16 values = 2 4 Value range: 0-15

15 Question: how much information can we store in a byte? 1 byte = 8 bits 256 values = 2 8 Value range: 0-255

16 Assume we want to store integer values

17 Assuming byte-addressable memory

18 Assuming byte-addressable memory Number of bytes accessible in memory = bit size of the address

19 Question: what is a kilo?

20 Question: What is a Kilobyte (KB)? Better question: How many bytes can be accessed via a 10-bit address? 1024 addresses = 2 10

21 Question: What is a Megabyte (MB)? Better question: How many bytes can be accessed via a 20-bit address? 1,048,576 addresses = 2 20

22 Question: What is a Gigabyte (GB)? Better question: How many bytes can be accessed via a 30-bit address? 1,073,741,824 addresses = 2 30

23 Question: What is a Terabyte (TB)? Better question: How many bytes can be accessed via a 40-bit address? 1,099,511,627,776 addresses = 2 40

24 Question: What is a Petabyte (PB)? Better question: How many bytes can be accessed via a 50-bit address? 1,125,899,906,842,624 addresses = 2 50

25 Question: What is a Exabyte (EB)? Better question: How many bytes can be accessed via a 60-bit address? 1,152,921,504,606,846,976 addresses = 2 60

26 Question: What is a Zettabyte (ZB)? Better question: How many bytes can be accessed via a 70-bit address? 1,180,591,620,717,411,303,424 addresses = 2 70

27 Question: What is a Yottabyte (YB)? Better question: How many bytes can be accessed via a 80-bit address? 1,208,925,819,614,629,174,706,176 addresses = 2 80

28 Pattern Megabyte: (2 20 =2 10 x 2 10 ) =1024 Kilobytes Gigabyte: (2 30 =2 10 x 2 20 ) =1024 Megabytes Terabyte: (2 40 =2 10 x 2 30 ) =1024 Gigabytes Petabyte: (2 50 =2 10 x 2 40 ) =1024 Terabytes Exabyte: (2 60 =2 10 x 2 50 ) =1024 Petabytes Zettabyte: (2 70 =2 10 x 2 60 ) = 1024 Exabytes Yottabyte: (2 80 =2 10 x 2 70 ) = 1024 Zettabytes

35 Class Activity: Team 1 Team 2

36 Preparation time = minutes Each team will: Class Activity: من سيربح االلوان Elect a team coordinator Team coordinator: cut the bullets and distribute among sub-groups of 5 10 each Sub-group will: Write a question for the opponent team with 4 answer choices about the bullet assigned to them (make it hard and confusing) Study their assigned bullet to be able to answer the other team s question Yellow team will use yellow paper & scissors and blue team will use blue paper & scissors (provided) Team coordinator: cut papers into 16 cards and hand to sub-groups Sub-groups: write 1 question per card Hand your questions to your team s coordinator.

37 Team coordinators take turns choosing one question from the pool and asking the opponent team. Each answer is worth 5 points Lecturer keeps score on the white board Class Activity: من سيربح االلوان Winning team will cut the red ribbon and each member of the team will take a piece Collect as many ribbon pieces as possible throughout the semester and redeem prizes at them end

38 H.W.1: Pick any domain and find a program to report on

39 H.W.1: Answer the following about your program of choice: Q1: What is the name of the program? Q2: What is the download link of the program? Q3: What is the latest version available? Q4: Are there 32-bit and 64-bit versions available?

40 H.W. submission: 2 options You can write answers in English or Arabic (or both!) You can submit either: A Word document with your answers An HTML document with your answers

41 If you choose to learn HTML Use any text editor I like Sublime Text 2
