What is Flash Memory?
Flash memory (sometimes called "flash RAM") is a type of constantly-powered nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. It is a variation of electrically erasable programmable read-only memory (EEPROM) which, unlike flash memory, is erased and rewritten at the byte level, which is slower than flash memory updating. Flash memory is often used to hold control code such as the basic input/output system (BIOS) in a personal computer. When BIOS needs to be changed (rewritten), the flash memory can be written to in block (rather than byte) sizes, making it easy to update. On the other hand, flash memory is not useful as random access memory (RAM) because RAM needs to be addressable at the byte (not the block) level.
Flash memory gets its name because the microchip is organized so that a section of memory cells are erased in a single action or "flash." The erasure is caused by Fowler-Nordheim tunneling in which electrons pierce through a thin dielectric material to remove an electronic charge from a floating gate associated with each memory cell. Intel offers a form of flash memory that holds two bits (rather than one) in each memory cell, thus doubling the capacity of memory without a corresponding increase in price.
Flash memory is used in digital cellular phones, digital cameras, LAN switches, PC Cards for notebook computers, digital set-up boxes, embedded controllers, and other devices.
Zip Drive...
In addition to data backup, Iomega suggests these additional uses:
- Archiving old e-mail or other files you don't use any more but may want to access someday
- Storing unusually large files, such as graphic images that you need infrequently
- Exchanging large files with someone
- Putting your system on another computer, perhaps a portable computer
- Keeping certain files separate from files on your hard disk (for example, personal finance files)
The Zip drive can be purchased in either a parallel or a Small Computer System Interface (SCSI) version. In the parallel version, a printer can be chained off the Zip drive so that both can be plugged into your computer's parallel port.

Kerja kursus ICT
Sebagaimana yang telah anda semua maklum bahawa kerja kursus ICT adalah satu tanggungjawab yang perlu dilaksanakan oleh pelajar-pelajar ICT. Kerja kursus merupakan satu anugerah untuk anda semua kerana ia menyumbangkan 30 markah ICT SPM! Untuk itu disini saya ingin memaklumkan hari-hari yang saya peruntukkan untuk anda menghantar kerja kursus anda kepada cikgu.
Selasa : 2.00 - 3.30 pm.
Khamis : 2.00 - 3.30 pm.
Jumaat : 12.20 - 1.30 pm.
Senarai kerja kursus yang perlu anda laksanakan ada cikgu tampalkan di papan kenyataan di Makmal ICT. Sehingga bulan Mac ini saya yakin semua pelajar ICT tingkatan 4 dapat melunaskan semua kerja kursus untuk bab 1 iaitu;
1. Demo scan virus
2. Demo scan spyware
3. Presentation Power point - 5 to 10 slides.
Untuk tingkatan 5 pula kerja kursus yang perlu disiapkan ialah ;
1. Buku scraph
2. Projek Multimedia
Jangan bertangguh-tangguh kerana kerja kursus untuk bab-bab yang seterusnya sedang menanti anda dan pastikan anda menguruskan masa dengan betul dan cekap agar semua kerja siap, ada masa untuk rehat dan dalam masa yang sama skor A dalam peperiksaan. Pelajar ICT adalah pelajar yang SMART.

Mainframes, Supercomputers & Embedded computers
Mainframes
Mainframes
A mainframes is a large, expensive, powerful computer that can handle hundreds or thousands of connected users simultaneously. Mainframes store tremendous amounts of data, instructions and information. Most major corporations use mainframes for bunisess activities. With mainframes, large business are able to bill millions of customers, prepare payroll for thousands of employees, and manage thousands of items in inventory.
Supercomputers
A Supercomputers is the fastest, most powerfull computer and the most expensive. The fastest supercomputers are capable of processing more than 100 trillion instructions in a single second. With weights that exceed 100 tons, these computers can store more than 20,000 times the data and information of an average desktop computer. Applications requiring complex, sophisticated mathematical calculations use supercomputers. Large-scale simulations and applications in medicine, aerospace, automotive design, weather forecasting, nuclear energy research use a supercomputer.
- Consumers Electronics : mobile and digital telephones, digital televisions, cameras etc.
- Home Automation Devices & Appliances : microwave ovens, washing machines etc.
