Field Replaceable units, Chinese components (they cheaper to replace than repair).

Well, this depends on the person, as for me, i think Huawei E583C is the best wireless router, this is an article about how to Select Your Best Router:

many card readers are that size, some fan comtrollers, and especially a 3.5 floppy drive- but do you use one?. You can also put hard drives there. Are you looking for a case? A good cheap case for beginners is an Antec 300. More beefy cases are Antec 900, CM HAF 932, CM Sniper, Antec 1200, Azza Solano.... But these are reasonable priced cases. Lian Li and others make real nice expensive cases that you may like as well, but I never really looked at them.

A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.

Short for Level 1 cache, a memory cache built into the microprocessor.

Short for Level 2 cache, cache memory that is external to the microprocessor. In general, L2 cache memory, also called the secondary cache, resides on a separate chip from the microprocessor chip.

As more and more processors begin to include L2 cache into their architectures, Level 3 cache is now the name for the extra cache built into motherboards between the microprocessor and the main memory.

the l2 cache is now always built onto the processor for x86 archetechure

ultraviolet light, or UV light, is a type of electromagnetic radiation that has a wavelength somewhere between visible light and X-rays. It is widely used throughout the world, in everything from production of usable electricity (the sun's rays are ultraviolet) to the many common uses for a simple black light.

Sun Tanning

All sun tanning beds use ultraviolet lights in order to simulate the effects of sunlight against bare skin. Just like real sun bathing, people who use tanning beds run the risk of developing sunburn.

Hunting

Many hunters will use an ultraviolet light, such as a black light, to locate and follow a wounded animal. This is done by shining the light on the ground and following the illuminated blood trail.

Forensics

Forensic scientists will also use ultraviolet lights to look for clues at a crime scene.

CD/DVD Players

CD and DVD players use lasers, which are a form of ultraviolet light, to read information off of the disc.

Security

To fight counterfeiting, many government or otherwise sensitive documents will have some sort of ultraviolet verification. In other words, if you shined a black light over a $20 bill, you would see markings on an authentic bill that you wouldn't find on a fake.

If you touch the charged item to the ground, the charge will go into the ground. This is because static electricity is caused by either having too many or not enough elecrons. When toughed to the ground, the item will either get rid of the electrons or pick more up, making it neutral.

keys,mouse, camera, mic, trackpad, scanner etc, anything that will show up on your screen or come thorough your speakers really

The function keys can have different functions depending on what program you have open. Pressing the f1 key while using a graphics program might for example bring up a menu on the screen.

If for example you are in the properties window for a printer , you can highlight a tab then hit the f1 key. It will bring up a litttle box explaining the use of that tab.

Some programs dont use function keys. In general the instructions for using a computer program should tell you what if any function keys can be used.

The use of a separate disk controller frees the CPU to perform other tasks. In particular, the disk controller can manage DMA transfers, which otherwise would have to be done by the CPU. The disk controller also manages the movement of the disk head and reading or writing of the data on the disk. Again, without the disk controller, the CPU would be forced to perform these operations.

The computer's Random Access Memory (RAM) temporarily stores data and programs while your computer is on.

When the Semiconductor technology not in existence there was a usage of magnetic tapes and magnetic drums which were the Sequential access means If you currently at the position of words which is starts from 'A' so if you need to look up the words started from 'Z' then you've to go through all alphabets means b,c,d........y then you'll get your position at 'Z'. It's similar to Audio or Video cassette.....

But the Ram is Random Access means "The ability of a computer to find and go directly to a particular storage location without having to search sequentially from the beginning location"

The human equivalent of random access would be the ability to find a desired address in an address book without having to proceed sequentially through all the addresses.

Yes there is. The major advantage of an ISO is that burning it as an image preserves the bootloader, where extracting and burning the contents does not. The bootloader needs to go on a specific part of the CD/DVD/USB drive for it to be bootable. Just burning the contents does not do this.

ISO also makes a checksum of the entire ISO instead of each file it contains. That can be used to make sure that the download happened without error.

Yes it is true that memory caching is a method used to store data or programs in SRAM for quick retrieval. The North Bridge is the faster end of the hub that contains the graphics and memory controller.

Plug & Play devices can be inserted/removed while Computer is running.

A memory cell is an individual part of memory, usually just a single bit. A DRAM "cell" is composed of a transistor and a capacitor, with memory refresh used to keep the charged capacitors charged and the drained ones drained until the values change. A SRAM cell is comprised of a transistor latch gate using 4-6 transistors. SRAM memory takes more power but does not need refreshed.

This is usually when your backup battery has died. Inside the computer there is (basically) a watch battery that stores information like time/date when the computer is turned off. If it doesn't get any power, it can't remember or update with the internal clock.

ISA is the precursor to PCI. Standing for "Industry Standard Architecture" It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called "ISA PnP" peripherals. In the end, the combination of flexibility, ease of use, and greater capability allowed PCI to supersede ISA.

There are 3 DS3's in an OC3.

Generally an OC3 or higher capacity circuit will be used to deliver a DS3 due to distance limitations of the DS3.

ALU is primarily responsible for arithmetic and logical calculations and is not responsible for all the activities inside the processor. e.g. many processors have inbuilt memory controllers which interface with memory or bus drivers, bus arbiters all of which will be performing autonomous functions and will be interfacing with various sub modules through data or control signals. ------- A processor contains three basic components; an input/output unit, a control unit, and ALU's. The control unit manages all activities inside the processor itself. -----
