Inkjet Printer
Laser printers are Printer that uses laser technology toprint images on the paper. The laser recreates theimage on a negatively charged drum which will thencollect ink that is positively charged to attract to theareas of the image. The Paper is then negativelycharged therefore the positively charged ink is attractedto the paper and then is fused onto the paper.

Plotters
A printer that uses heated pins to "burn"images onto heat-sensitive paper. The pinsare electrically heated and brought intocontact with the specially treated papereasily, instead of with great impact. Thecoating on the paper discolors when heatedin this way. These printers, used incalculators and many fax machines, areinexpensive, but produce low-quality, lowresolution print. They are however, quiet andfast as they print.

a) Random-Access Memory (RAM)
• RAM is installed inside computers. RAM is also known asa working memory.
• The data in RAM can be read (retrieved) or written(stored).
• RAM is volatile which means the programs and data inRAM are lost when the computer is powered off.
• A computer uses RAM to hold temporary instructions anddata needed to complete tasks. This enables thecomputer CPU (Central Processing Unit) to accessinstructions and data stored in the memory very quickly.
• RAM stores data during and after processing.

b) Read-Only Memory (ROM)
• ROM is another type of memory permanently storedinside the computer.
• ROM is non-volatile. It holds the programs and datawhen the computer is powered off.
• Programs in ROM have been pre-recorded. It can onlybe stored by the manufacturer once done, it cannot bechanged.
• It has complex functions such as start up operatinginstructions, translators for high-level languages andoperating systems are placed in ROM memory.
• All the contents in ROM can be accessed and read butcannot be changed.

2. Secondary Devices
1. Secondary storage is another alternative storage tokeep your work and documents. It is very useful tostore programs and data for future use.
2. It is non-volatile, which means that it does not needpower to maintain the information stored in it. It willstore the information until it is erased.

a) Magnetic Medium
• Magnetic Medium is a non-volatile storagemedium. It can be any type of storage mediumthat utilizes magnetic patterns to representinformation.
• Example of magnetic storage are:– magnetic disk such as: a floppy disk, used for
off-line storage– hard disk, used for secondary storage– magnetic tape; including video cassette, audio
storage reel-to-reel tape and others

b) Optical Medium• Optical Medium is a non-volatile storage media that
holds content in digital form that are written andread by a laser. These media include various typesof CDs and DVDs.
• These following forms are often commonly used :– CD, CD-ROM, and DVD: Read only storage
– CD-R: Write once storage, the data cannot be erasedor written over once it is saved.
– CD-RW, DVD-RW and DVD-RAM: Slow to write butfast reading storage; it allows data that has beensaved to be erased and rewritten.

c) Flash Memory• Flash Memory is a solid-state, non-volatile,
rewritable memory that functions like RAM and ahard disk drive. Flash memory store bits ofelectronic data in memory cells just like DRAM(Dynamic RAM), but it also works like a hard diskdrive.
• Flash memory cards and flash memory sticks areexamples of flash memory.

THE DIFFERENCES BETWEEN PRIMARY ANDSECONDARY STORAGE
Is non-volatile, which means that itdoes not need power to
maintain the information storedin it.
Has a volatile memory for RAM andnon-volatile memory for ROM.
Refers to various ways a computercan store program and data.
An internal memory (inside theCPU) that can be accesseddirectly by the processor.
Storage capacity is larger.Storage capacity is limited.
Examples : Floppy disc, Hard disk,CD-ROM, USB drive
RAM / ROM.
Alternative storage in a computer.Known as the main memory of a
computer.
