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.

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

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.

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.

America is an unusually religious nation.

In terms of my development as an artist, playing Professor Sprout wasn't all that important because she is well within my capabilities as an actress. But in terms of marketability, it made an enormous difference.

One gets the impression that Elvis Presley does what his business advisors think will be most profitable. My advice to them: Put Elvis Presley in the studio with a bunch of good, contemporary rockers, lock the studio up, and tell him he can't come out until he's done made an album that rocks from beginning to end.

I'm my best billboard.

The central conservative truth is that it is culture, not politics, that determines the success of a society. The central liberal truth is that politics can change a culture and save it from itself.

A grave is such a quiet place.

I don't throw around the word 'brother' because I'm so, so close to my real-life brothers and my real-life sisters, and being a brother is so important to me.

I don't want to be in magazines everyday, because I don't want people to get used to one thing.

The speed of the human mind is remarkable. So is its inability to face the obvious.

At the end of the day, it is about working in a good film. It's the films that you leave behind that matter.

From the stage, I can reach a large audience, and you learn from being on stage how much a song reaches, what extent of the crowd a song can reach. I write in a way that can reach most of the audience, but I also wanted to have truly intimate moments as well, many intimate moments, more so than the big moments.

Once a woman has given you her heart, you can never get rid of the rest of her.

I think that a strong Israel is the only Israel that will bring the Arabs to the peace table.

If you come up to me in the street, I am going to be delighted to meet you. I became a television star to entertain people, to spread goodness into the world.

But there was something psychological happening there that was just a little bit different. And the other thing was, there was no stigma. Kids weren't going into the 'Center-for-Kids-That-Need-More-Help' or something like that. It was 826 Valencia.

War's dirty little secret is that some men love it.

We should concentrate our work not only to a separated housing problem but housing involved in our daily work and all the other functions of the city.

It is important to nurture any new ideas and initiatives which can make a difference for Africa.

I can't see anything that I don't like about you.

One trait of addictive families is that we never recognize our own addictions.

As far as I know, the most conservative estimates of the number of Americans who would be killed in a major nuclear attack, with everything working as well as can be hoped and all foreseeable precautions taken, run to about fifty million.

I dug the idea that I was being perceived as the black sheep of my family, but for me, it was like, I was a rebel, and that to me was most important.

The best way to get people to connect with an issue is to humanize it. You can do so much more powerfully with music and touch the heart.

I have the loving support of my girlfriend who still attends Wake Forest and is nearing graduation. She helps me cope with the everyday rigors of being an NBA player.
