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.

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.

To tackle the big and relevant issues of the day with bold and innovative ideas is without question the most rewarding way to serve.

It is the greatest of all advantages to enjoy no advantage at all.

We young Filipinos are trying to make over a nation and must not halt in our march, but from time to time turn our gaze upon our elders. We shall wish to read in their countenances approval of our actions.

Ah, lives of men! When prosperous they glitter - Like a fair picture; when misfortune comes - A wet sponge at one blow has blurred the painting.

And how can you achieve such concentration? By recognizing that everything you do is important to God, and is one vital piece of the larger picture of your life.

I was raised to believe in myself. I know I'm cool. I'm not trying to brag or say I'm the man or anything like that. I don't lie or cheat, and I'm not mean to anybody. I treat people with respect.

If you do have a team where every rider has a huge list of results, that means everybody wants to do the race for themselves. The strongest team in the Tour is not the strongest team on paper.

The obvious is always least understood.

I loved 'Lost,' from beginning to end.

Commercial Art tries to make you buy things. Graphic Design gives you ideas.

When you share your last crust of bread with a beggar, you mustn't behave as if you were throwing a bone to a dog. You must give humbly, and thank him for allowing you to have a part in his hunger.

And it is practically the same in the case of the four or five million poor peasants in France, and also for Switzerland, Belgium, Holland, and two of the Scandinavian countries. Everywhere small and medium sized industry prevails.

A human being fashions his consequences as surely as he fashions his goods or his dwelling his goods or his dwelling. Nothing that he says, thinks or does is without consequences.

The depth of concern people feel about UKIP is not always matched by depth of understanding.

People are afraid to ask musicians to be involved in projects because they anticipate being turned down. Young artists hesitate before contacting me. People in my position don't get approached often enough.

I wasn't enjoying golf much. I was kind of getting a little bit tired, I was getting a little bit moody, and I was constantly getting angry. That's not me. And when I saw that I knew I had to change.

When I see a woman who is all gaunt and emaciated, I don't think she's beautiful. She reminds me of a Chihuahua that's freezing and shaking.

The one thing I could do with my eyes closed is my Grandma's schnecken.

To make something look real and alive, nothing can be symmetrical because nothing in real life is symmetrical. You have to make it look organic.

I was too young to be an avid enthusiast for the franchise, but like billions of people I remember as a child sitting around with the family on a Friday night with pizza and popcorn and a 'Die Hard' movie on.

Immigration is the issue that tells us who is with us and who is against us; there's no question about it. And it's very simple to understand why - half of all Latinos over 18 years of age were born outside the United States. It really makes no sense to attack them and criticize them if you want their vote.

The creative tension with spirituality vs. practicality in the world of politics is a vital conversation.

You dont go around grieving all the time but the grief is still there and always be.

When I'm making documentaries, I think a lot about how fiction films play. I want them to have the pacing, the twists and the character development of fiction films.
