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.

You know, I think I'm a stronger person for realizing that you can't make everybody love you.

When I look back on my career - if that's what it is - it looks a bit like a crazy quilt, and I think it's just really because, when one job has finished, I've never really been in a position where I had three or four options.

When I got to New York, I had no place to sleep. The pay from 'Sesame Street' wasn't enough to rent an apartment. I was staying on people's couches. I stayed in the dressing room until they found out. I stayed with Jim Henson and his family for a week, and I wanted to do that permanently. I didn't dare ask, though.

When we contemplate the heroes of Christianity, and compare our feeble efforts with their astonishing performance and self devotion, we should fall into despair, were there not a few softening features, by which they are brought back to the ranks of humanity.

Popular as Keynesian fiscal policy may be, many economists are skeptical that it works. They argue that fine-tuning the economy is a virtually impossible task, and that fiscal-stimulus programs are usually too small, and arrive too late, to make a difference.

My mother wanted to be a teacher when she was young, and my father didn't approve of it, so she fought very hard to become one. And she did it. So when I said I wanted to become an actress, my mother was very supportive. She always said to me, 'There's no such thing as 'can't.'

Have a definite opinion.

My parents have been with me every step of the way.

There's nothing remotely interesting to me about marketing music as a product.

It was my dream that I had clenched in a fist of discontent and wouldn't release. But time had now pried every finger open. There is peace in an open and upraised hand that isn't grasping for anything.

Leadership is a matter of having people look at you and gain confidence, seeing how you react. If you're in control, they're in control.

It is always sad to write about prejudice, but sometimes when we see it being played out in the lives of fictional characters, we can recognize it in our own lives.

It takes courage to grow up and turn out to be who you really are.

I think I have character, and that is what people like in me.

For me, peace should provide security to the Jewish people.

The thing that impresses me most about America is the way parents obey their children.

My attitude to writing is like when you do wallpapering, you remember where all the little bits are that don't meet. And then your friends say: It's terrific!

I feel like I've always been doubted or slighted. Let's be honest. When you're a walk-on, you don't start for a No. 1 team, a national championship contender. You just don't. A walk-on is a guy who plays scout team, who's just happy to be on the team.

If a book is worth reading it is worth buying.

For me, being memorable is more important than winning.

People have a tendency to see country life through rose colored glasses.

I have a tip that can take 5 strokes off anyone's golf game. It's called an eraser.

Neutral men are the devils allies.

Nobody really knows what makes a hit TV show.
