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.

I had already developed inherited back problems. I had degenerative disk disease, a form of scoliosis, arthritis. And I truly believe that if it weren't for the use of steroids - I'm not saying steroids is for everyone, but in my case in general, if I have not used steroids, I mean, physically right now I'd probably be a wreck.

The day we dispose of the idea of disposability will be a great one for the planet.

I think the reason for my fascination with craft is what it represents, what it means in our culture, what it means in our history and in humanity. It was the idea that you could go to your butcher to get something, you could go to your tailor to get this, and you could go to your cobbler to get that.

My parents gave me a strict upbringing, which at times has caused me to suffer distress but today I am grateful to them for it.

Fire taps something ancient and vital in each of us, something both snarling and reverential.

The pain of discipline is nothing like the pain of disappointment

Consular cards were not designed to be identification and no treaty recognizes them as such. Legal travelers, visitors and long-term residents carried passports, visas or green cards for that purpose.

You have to know evolution to understand the natural world. And that cannot be a threat to people of faith. There's a serious problem if you are forced by your faith to reject the most well-supported theory in all of science.

Ah! Young people, travel if you can, and if you cannot - travel all the same!

Oh, I am not naturally gifted in dancing in any way! Stupidly, I didn't go to those classes in drama school. I was like, 'I don't need that; I'll never be dancing in anything.'

In line with international law, only the U.N. Security Council could sanction the use of force against a sovereign state. Any other pretext or method which might be used to justify the use of force against an independent sovereign state are inadmissible and can only be interpreted as an aggression.

Winning is a state of mind that embraces everything you do.

Imagine, and it shall be. There are no limits.

Be legendary.

We have to fight radical Islam wherever it exists. It's in Afghanistan, it's in Saudi Arabia, throughout the Middle-East in big numbers and it's in the United States.

I think that some of our soldiers die in the battlefield and some come home to bad health and die prematurely, just by the nature of the kind of business they're in.

I suffer from the delusion that every product of my imagination is not only possible, but always on the cusp of becoming real.

A fantasy film is often improved by some kind of human reality.

Generally, with films, what tends to happen is that a few people get a lot of momentum out of it, and a lot of people don't.

As soon as I started writing the first batch, I had a vision. I saw me on stage playing a certain type of music. I want to take these blues melodies over aggressive guitars. I heard the sound I wanted to make. I knew what I wanted to do. It wasn't ever there before.

The ability of a person to atone has always been the most remarkable of human features.

The recycling in my house was imposed by my kids.

Women tend to double-speak - I'm definitely guilty of that.

I've raised three kids: my wife and I have three kids. I've observed through direct contact the adults they are now is partially the product of where they came from and what we did. With them growing up, but partially how they were wired at birth.
