Computer Storage Fundamentals
Megabyte
(MB)Kilobyte (KB)
Gigabyte (GB) Terabyte (TB)
Petabyte(1 quadrillion bytes!)
Storage capacities
Bit vs. Byte
Reported by: Mary Marjorie Co
Don’t byte more than you can chew!
Storage Trade-offs
• Note the cost/speed/capacity trade-offs as one moves from semiconductor memories to magnetic media, such as magnetic disks and tapes, to optical disks.
• High-speed storage media: cost more per byte and provide lower capacities.
• Large capacity storage media: cost less per byte but are slower
• Semiconductor memories: used mainly for primary storage, though they are sometimes used as high-speed secondary storage devices.
• Magnetic disk and tape and optical disk devices: used as secondary storage devices to greatly enlarge the storage capacity of computer systems.
• Secondary storage devices: provide a more permanent type of storage media for storage of data and programs.
Reported by: Mary Marjorie Co
Semiconductor Memory
• Primary Storage = Microelectronic Semiconductor memory chips
• 256 MB or more can be added to increase computers memory
• PROS: Small in Size, great speed, shock and temperature resistance
• CONS: Volatility, unstable electric supply may damage chips and cause loss of data
Reported by: Veronica Nicolas
Types of Semiconductor Memory
1. Random Access Memory (RAM)• Also called read / write memory• Highly volatile
2. Read Only Memory (ROM)• Data in ROM can be read but not erased or
overwritten• Firmware – data permanently burned into
storage cells during manufacture• PROM – Programmable Read Only Memory• EPROM - Erasable Programmable Read Only
Memory
Reported by: Veronica Nicolas
Magnetic Disks
• Secondary storage, metal disks that are coated on both sides with an iron oxide recording material
• Several disks mounted together on a vertical shaft , rotates the disk at speeds of 3600 to 7600 rpm. Data are recorded on tracks that uses binary codes
• Types of Magnetic Disksa. Floppy Disks b. Hard Disks
Reported by: Veronica Nicolas
Redundant Arrays of Independent Disks (RAID)
• Disk arrays of interconnected microcomputer hard disks, 6-100 small hard disk drives combined into a single unit.
• Fault tolerant capacity, redundant design offers multiple copies of data on several disks.
• Storage Area Networks – high fiber channel local area network that connects one RAID to another.
Reported by: Veronica Nicolas
Magnetic Tape
• Includes tape reels and cartridges in mainframes and midrange systems, small cassettes or cartridges for PC
• Applications:– 36 magnetic tape cartridges in robotic
automated drive that can directly access hundreds of cartridges
– Long term archive and back up
Reported by: Veronica Nicolas
Optical Disks
• Optical disk storage involves technology, which is based on using a laser to read tiny spots on a plastic disk. The disks are currently capable of storing billions of characters of information.
• Types: CD-ROM, CD-R (Compact disk recordable), CD-RW (CD-rewritable), DVD (Digital Video Disk or Digital Versatile Disk), DVD-ROM, DVD–RAM
• Business Applications– Image Processing: long term storage of files
and images– Fast access to reference materials– Large storage capacity
Reported by: Veronica Nicolas
Radio Frequency Identification
• A system for tagging and identifying mobile objects
• Allows objects to be labelled and tracked as they move
What is an RFID Chip?• A device that contains an antenna to receive
and transmit signalsTypes of RFID• Passive RFID – do not have its own power
source, derives power from signal sent by submitter
• Active RFID – self powered, can transmit signal on their own
Reported by: Veronica Nicolas
RFID Privacy and Ethical Concerns
• Unawareness of the presence of an RFID chip makes it possible to gather sensitive data without the individual’s consent
• Payment for a tagged item using a credit card makes possible the deduction of identity of the purchaser
• Read Range – limited to the distance over which the tag can draw enough power from the source to power the tag.
Reported by: Veronica Nicolas
Predictions for the Future:
Some of Ray Kurzweil’s Fearless Forecasts
Key Takeaways• Advancement in
technology will bring tremendous changes in the way we live today.
• Robotics and Artificial Intelligence will increase and be part of human life.
• Medical problems will be solved through technology.
• The summed computational powers of all computers is comparable to the total brainpower of the human race.

GOLF TALK
Playing Golf in Philippines is convenient and hassle-free since each golfer has the luxury of having a caddy. (In US and Canada players caddy themselves; in Asia, one caddy for every 4 players, while in the Philippines the ratio is 1:1 -- one caddy per player) Aside from carrying your bag and choosing which club to use , the caddy will tell you the direction and distance of your ball to the pin. In turn, most Filipino players are dependent on their caddies.
Example 2
GPS Voice: Golfers’ New Bestfriend
Reported by: Lourdes Mapalad
GPS Voice is a small GPS range finder that speaks, the first ever gadget introduced specifically for Golfers. It voices the balls’ distance and direction to the pin.

Reported by: Lourdes Mapalad
Now, golfers don’t have to look for course outline nor wait for the caddies instruction, once they
stand at the back of their ball, GPS Voice will tell them the distance from the Pin. (In golf accuracy in
reading distance is very important) With this new gadget, Filipino
golfers can play anywhere in the world even without a caddy.
