PROM (Programmable Read Only Memory) can be written to once, typically at the factory. EPROMs (Erasable Programmable Read Only Memory) and EEPROMs (Electrically Erasable Programmable Read Only Memory) may be “flashed,” or erased and written to multiple times.

Static Random Access Memory (SRAM) is fast, expensive memory that uses small latches called “flip-flops” to store bits. Dynamic Random Access Memory (DRAM) stores bits in small capacitors (like small batteries), and is slower and cheaper than SRAM.

The capacitors used by DRAM leak charge, and must be continually refreshed to maintain integrity, typically every few to a few hundred milliseconds, depending on the type of DRAM. Refreshing reads and writes the bits back to memory. SRAM does not require refreshing, and maintains integrity as long as power is supplied

Firmware stores small programs that do not change frequently, such as a computer’s BIOS (discussed below), or a router’s operating system and saved configuration. Various types of ROM chips may store firmware, including PROM, EPROM, and EEPROM.

The term “flashing” derives from the use of EPROMs: flashing ultraviolet light on a small window on the chip erased the EPROM. The window was usually covered with foil to avoid accidental erasure due to exposure to light. EEPROMs are the modern type of ROM, electrically erasable via the use of flashing programs.

A Programmable Logic Device (PLD) is a field-programmable device, which means it is programmed after it leaves the factory. EPROMs, EEPROMS, and Flash Memory are examples of PLDs.

Flash Memory - Flash memory (such as USB thumb drives) is a specific type of EEPROM, used for small portable disk drives. The difference is any byte of an EEPROM may be written, while flash drives are written by (larger) sectors. This makes flash memory faster than EEPROMs, but still slower than magnetic disks.

I am definitely a storyteller, but probably not a traditional Storyteller.

The differences between the two sexes is one of the important conditions upon which we have built the many varieties of human culture that give human beings dignity and stature.

Revising a screenplay is much more frustrating than revising a song because you have to read through the entire work again while you are changing stuff. It is a lot easier to edit a song.

There have been so many people who have said to me, 'You can't do that,' but I've had an innate belief that they were wrong. Be unwavering and relentless in your approach.

So easy to fall into a rut, isn't it? Why should ruts be so comfortable and so unpopular?

Unpleasant reading on the subject of anger tells us that there's not really anything wrong with it. In limited amounts. It can even be a good thing. A pressure valve.

I am actively campaigning for 'chest hair' to become an Olympic sport.

No one is too big to be courteous but some are too little.

I think we should all talk to our enemies and talk to our friends. Talk! That's the only way we'll find solutions.

In international affairs, you never threaten things you're not prepared to do.

Give light, and the darkness will disappear of itself.

Along with success comes a reputation for wisdom.

I'll just say it: I'm not the sharpest tool in the box. Being forced to go back to school is still a fear of mine.

There are events which are so great that if a writer has participated in them his obligation is to write truly rather than assume the presumption of altering them with invention.

I always try to tell a good story, one with a compelling plot that will keep the pages turning. That is my first and primary goal. Sometimes I can tackle an issue-homelessness, tobacco litigation, insurance fraud, the death penalty-and wrap a good story around it.

I'm perfectly happy to color within the network lines when I have to.

The first test of a truly great man is his humility. By humility I dont mean doubt of his powers or hesitation in speaking his opinion but merely an understanding of the relationship of what he can say and what he can do.

If the Rolling Stones are playing a concert across town, that's not my audience anyways. But I do find that there's a lot of people coming back around to see me again.

Barack Obama's decision to come out in favour of gay marriage may be a historic occasion, but it is not an isolated one. His administration has been making pro-gay noises for some time; his demographic in the upcoming election is young and educated, precisely the group that favours equality for the LGBT community.

The greatest explorer on this earth never takes voyages as long as those of the man who descends to the depth of his heart.

Nature gives us all, including Prof. Lorentz, surprises. It was very quickly found that there are many exceptions to the rule of splitting of the lines only into triplets.

He's dreaming with his eyes open, and those that dream with their eyes open are dangerous, for they do not know when their dreams come to an end.

We were gradually playing larger venues and in the early days PA systems were kind of non-existent. So to play loud, we had to use louder equipment. The PA systems back then didn't mic the instruments - only the vocals.

Talent, like beauty, to be pardoned, must be obscure and unostentatious.
