  2. REVIEW • What’s a Computer? • Who is Pascal? • Transistors were used in Which Generation of Computers? • What else do you remember from last class?

  3. Binary: • To computers, everything is a number. • Since a computer is really just millions of tiny switches, all a computer understands is off and on, which we represent with 0s and 1s. • Binary Numbers • 00000001 = 1 • 00000010 = 2 • 00000011 = 3 • ... • 10000001 = 65 • ... • 11111111 = 255

  4. Storage Amounts: Bit = 0 or 1 Byte = 8 bits Kilobyte (KB) = 210 bytes = about one thousand bytes Megabyte (MB) = 220 bytes = about one million bytes Gigabyte (GB) = 230 bytes = about one billion bytes Terabyte (TB) = 240 bytes = about one trillion bytes

  5. Storage Amounts: 1GB ≈ 250 songs 1GB ≈ 250,000 typed pages In 1995, 1GB cost $15,000 Today, 16GB SD Card for $5.99 at Newegg.com

  6. Computer Parts: • CPU - central processing unit • the brains of the system • can only perform simple operations like add two numbers, or compare two numbers • Main Memory / RAM • holds all data and instructions for all the programs you are running • Input/Output Processors • they talk to the other parts such as the USB ports, the disk drive, etc. • Bus • the shared communication channel for all the components • Motherboard • holds the CPU and memory

  7. Internal Diagram Internal Memory / RAM (instructions and data) B U S CPU ROM Disk Drive IOP IOP IOP IOP USB Port

  8. Hardware Terms: • Embedded Computer • Machine Types: • Tablet • SmartPhone • PC • Laptop • Workstation • Desktop • Server • Supercomputer • Cache Memory

  9. Operating Systems: • Purpose = control the hardware • access to the CPU • internal memory management • file storage on disks • etc • Discussion: • Microsoft Windows vs Mac and Linux

  10. Mobile Operating Systems: • Discussion: • Android, Apple, RIM, Microsoft, Symbian

  11. Homework • Watch the entire Randy Pausch Time Management video found at • http://www.youtube.com/watch?v=oTugjssqOT0 • Write 2-3 pages on up to 3 things that you can start doing today, using technology, to improve your time management skills. • Email the paper to me at roudaj@winthrop.edu no later than the start of our next class.

  12. Next Class • How the Internet Works • Who owns it? • How do you create a new domain name? • What is a "domain name"? • How does it work? • What can it do?
