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.

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

Education is the process of driving a set of prejudices down your throats.

It's up to you to be responsible for how you feel if you're not happy. Your happiness lies in your hands. You can't rely on a man to make you happy or complete you. That starts with you.

Trust your gut feeling about things listen to what others are saying and look at the results of your actions. Once you know the truth you can set about taking action to improve. Everyone will be better for it.

All you may need to be happy is love, but to survive you need money!

The only one who can tell you ‘you can’t’ is you. And you don’t have to listen.

Every disappointment gives you opportunity to make another appointment.

As the BBC approaches the final phase of decisions about its future, it will be important for those involved to be established in post and ready to take responsibility for implementation of the outcome.

Gay rights is just one of the social issues I'm interested in. I think that people might be less tense about it if we would all accept the fact that not everyone is wired the same way.

I have long argued that no one should be allowed to write opinion without spending years as a reporter - nothing like interviewing all four eyewitnesses to an automobile accident and then trying to write an accurate account of what happened.

Running was a part of my hardwiring, and that's what I wanted to do. So this is what I tell people who talk about wanting to follow their passion. 'It doesn't have to be running. It can be basket weaving. Be the best basket weaver in the world. Throw your heart and soul into it.'

I just sing what I feel in my heart. I ain't trying to prove nothing, and I don't think I ever did.

Rejoice for those around you who transform into the Force. Mourn them, do not. Miss them, do not. Attachment leads to jealousy. The shadow of greed, that is. Train yourself to let go of everything you fear to lose

Even the highest forms of sacrificial worship present much that is repulsive to modern ideas, and in particular it requires an effort to reconcile our imagination to the bloody ritual which is prominent in almost every religion which has a strong sense of sin.

It's been hard, but I've finally come to the realization that it's okay to not be perfect.

With the second 'Captain America,' we really pushed the envelope in terms of what this guy is capable of, which I was excited to see. Because in the first 'Captain America,' he's just strong. In 'Avengers,' it was still, in my opinion, a little bit 'punch, punch, kick, kick.'

I'm an FFH: a Formerly Fat Housewife.

By the time I was 7, I did walk-ons, catalogue modeling, you name it. In the Queens where I grew up, you didn't go bowling on Saturday; you went to dancing school.

It is fun to be in the same decade with you.

One person with a belief is equal to ninety-nine who have only interests.

When I was a teenager, I did a lot of pull-ups and push-ups. Every night before bed, I'd do 150 - in sets of 30 or so. Looking back on it now, I'm not totally sure that's the best way to improve as a climber. But it did make me a lot better at doing pull-ups and push-ups.

Reading is such a personal thing to me. I'd much rather give someone a gift certificate to a bookstore, and let that person choose his or her own books.

Jack Kerouac influenced me quite a bit as a writer... in the Arab sense that the enemy of my enemy was my friend.

My mother went into the Peace Corps when she was sixty-eight.
