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.

The function of good software is to make the complex appear to be simple.

I've reached a point in my career when I can demand certain conditions, and one of them is a weekend break every three weeks during the shoot.

I trust the integrity of the British government and the British soldiers.

I was just a normal athlete. My mother tried to spark something in me. She was an athlete in high school before she got pregnant with my older brother. She was 16, and that was it for her when it came to track and her education.

I'm not so vain as to believe that my involvement changes anything whatsoever.

I don't understand why some people will only accept a guitar if it has an instantly recognizable guitar sound. Finding ways to use the same guitar people have been using for 50 years to make sounds that no one has heard before is truly what gets me off.

I'm born in Liverpool, I'm a Liverpool supporter.

Most of my movies get about a third raves, a third vicious attacks, and a third in-between.

If you have never been hated by your child you have never been a parent.

I have thought there was some advantage even in death, by which we mingle with the herd of common men.

My mother and my grandmother are pioneers of Mexican cuisine in this country, so I grew up in the kitchen. My mom, Zarela Martinez, was by far my biggest influence and inspiration - and toughest critic.

My aim is to put down on paper what I see and what I feel in the best and simplest way.

Cake for later cake as a way of life.

It is through this mysterious power that we too have our being and we therefore yield to our neighbors even to our animal neighbors the same right as ourselves to inhabit this vast land.

Labour's task for government is to build consent for an outward-looking Britain as the best way to advance not just our interests, but also our values at a time of challenge, both at home and abroad.

As an actor, you try to bring as much of yourself to a part to try and create a feeling of authenticity and emotional truth and resonance.

I don't consider myself sexy. I'm kind of a nervous person in general. I'm socially awkward. I'm not tall and sensuous. I usually wear sweats everywhere I go. Oh, and I burp a lot.

Isn't it interesting that God appears holy when he's gracious?

We need houses as we need clothes architecture stimulates fashion. Its like hunger and thirst you need them both.

'Greek' is basically a show about sororities and fraternities. It follows Casey Cartwright, played by me, her younger brother, and all the people that are involved in their lives from the different fraternities.

Be sure that you speak with unfeigned lips.

Well I am from Annapolis Maryland. I went to High school in Baltimore, but I grew up in Annapolis. It was a cute town. We lived on a waterfront community. It was good, even though I don't really fit the preppy boater kind of style.

A wise man ... proportions his belief to the evidence.

I am attracted to the complexities and deeper truths of characters, and I can't name a favourite role any more than I can name a favourite food!
