Computer Hardware Quizzes Online & Trivia

The battery is only used when the ac power fails-2. they are on all the time-3. they are far less expensive-when an sps is used there is a momentary gap, usually about 1ms or less, between when the power goes off and when the sps starts supplying power. spss are also less expensive and are not used at all times. 12. a, b, c, d. when turning on a system that shows no signs of life you must consider all of these as potential problems. 13. a, c. all processors require a heat sink. a heat sink is a finned metal device that radiates heat away from the processor. an active heat sink (a heat sink with a fan) is required for adequate processor cooling on current systems. some older systems used a specially designed duct to direct airflow over a processor with a passive heat sink (a heat sink without a fan). most motherboards northbridges use passive heat sinks. 14. a. thermal compound (also known as thermal transfer material, thermal grease, or phase change material) provides for the best possible thermal transfer between a component (for example a cpu) and its heat sink. this prevents cpu damage. the fan and adapter cards should not have thermal compound applied to them. as a side note, most northbridges do not have fans.

The instructions that tell a computer what to do and how to do are the software. This is pretty much the equivalent of the instruction booklet that comes with any piece of furniture to put it together. If the computer follows them step by step, then nothing will go wrong. Everything will work correctly when a computer is able to read the software. When the software is corrupted, then the computer may freeze, crash, or show the infamous “blue screen of death” that often means something is very wrong with a computer. When this happens, the vital instructions have not been completed, and that is not good. Corrupted software can also lead to other programs on the computer not working right before any of the above drastic measures happen.

A. RCA cable/coaxial cable. RCA cables are used to connect devices like VCRs and DVD players to TV sets or CD players to stereo receivers. RCA audio cables come in pairs with two connectors on each end, a red one for right stereo and a white (or black) connector for left stereo. They are often bundled with video cables.

When it comes to the most efficient computer mouse ever you have to look at one that is around today and that one can easily say that the distinction can go to the Logitech LX Master. Logitech has long been in the computer industry and they are well known for their maufacturing and development of computer peripherals such as mice. The Logitech LX Master is well known for its ergonomic feel but also for its functionality. The big reason why the Logitech LX Master is so efficient is that it is perfect for BlueTooth technology. A lot of mice out there have not embraced this technology but the Logitech LX Master has done that. It makes it a device that can be used for all kinds of different things. It could be embraced by the casual computer user right on up to the experienced gamer and office worker. The versatility of the Logitech LX Master is one of the key reasons why this device is very efficient. It has so many different uses and at the same time has an excellent feel that is comforable for any tasks that need to be done on the computer.

It's actually RAM and DRAM (Dynamic RAM) - This should probably be changed.

As technology has advanced there are different devices that have come into play that help in transferring data. At one time it was difficult to transfer data between computers. Slowly as technology unraveled, the floppy drives were developed. They could hold only minute amounts of data but they were the start of a revolution. There were jump drives and finally, now we recognize memory cards. These memory cards have immensely small sizes and are capable of holding Gbs worth of data. With advancement of technology, transferring data is no longer a problem. In fact, most people have shifted to cloud which allows them to access data wherever they go.

You can use a jump drive, a floppy disk, or a memory card. Most computers these days do not have a place to read a floppy disk anymore, so this isn’t a very good option anymore. A jump drive, or a flash drive, is a more common option. Small ones, often holding between two and four gigabytes, can be purchased at almost every kind of store, for less than $10. Even packs with multiple can be purchased for less than $20 if you find the right store and brand. Memory cards are also become harder to read on computers. SD cards, a type of memory card, is often what a computer can read without any kind of help from other devices.
