What are the three example of hardware in computer?
Hardware refers to the physical components of a computer, for example,
Mouse- User interface Hardware
Processor- The 'brain' of the computer
Hard Drive- Stores data (your files and stuff)
Yes, and that "aux" line is usually for the CPU fan.
What slimline form factor is similar to ATX?
There are no similar form factors to ATX if you're talking about a slimline. Slimline form factors are NLX and LPX. The form factors to ATX are BTX, Micro-ATX, and Flex-ATX. There is no correlation between slimline and ATX.
What is the main purpose of a server?
Servers, as their name suggests, provide a service. This can mean a wide variety of things. Some servers are configured for file storage (i.e. NAS [network-attached storage], FTP [file transfer protocol]), while others specifically respond to requests to provide content (such as Web servers [you're making use of one now if you're browsing the Web!]). Some can be used for managing network traffic (e.g. a corporate intranet) as seen in enterprise or large-scale business set-ups.
ROM stands for Read Only Memory.
The ROM is non-volatile memory;it retains stored information even if the power is turned off (unlike RAM).This is basically used for storing programs and data that need not be altered one stored.
Processor uses ROM to store and execute programs instructions.However it is a type of prime memory and not a storage memory,therefore don't compare it with Hard Disks or CDs and DVDS etc
As the name itself suggests,the information can only be read not deleted,altered or even overwritten.This means that once a bit pattern is stored ,it is permanent or at least semi-permanent (if supports alteration).
The permanent groupincludes two types ,viz. ,ROM and PROM (Programmable ROM).
The semi-permanent also includes two types ,namely,EPROM (Erasable PROM)and EE-PROM (Electrically Erasable PROM). ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM ), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
If you ever do the hardware setup procedure with your computer, you effectively will be writing to ROM.
What does the power supply of a computer do?
- A power supply's job is to convert an Alternating Current (AC) signal coming from your wall outlet into a usable Direct Current (DC) signal. Simply stated, this process is done by stepping down the input voltage level with a transformer and then rectifying it to convert to DC. Once the DC signal is generated it is used to power all the devices and components of your system. In order to distribute the signal around to every component, many internal or external splitters can be attached to satisfy the number of connected devices. Usually a preset number of leads are provided by manufacturers to make this splitting procedure simple or even unneeded to the end user (as proper voltage values must adhere to specifications). From there, voltage regulation (often in the way of capacitors) is used to prevent your power supply from outputting too much or too little power. This protective mechanism is often called over current protection, over voltage protection, or over power protection. It is always important to ensure that your power supply has built-in regulation capabilities or spikes / sags due to fluctuations from the supply could damage your components. Alternatively, connecting your power supply to an Uninterruptible Power Supply (UPS) unit can greatly eliminate any potential harm due to external conditions on the unit.
- For computers the power supply is most responsible for providing power to the motherboard, your hard drive, CD drives, expansion cards, etc. In most cases, a single PSU unit (as opposed to a redundant power supply setup where multiple PSUs are cascaded in case one fails) is responsible for powering all parts internal to the system. Some external devices such as keyboards, mice, and external drives may also draw power either directly or indirectly from the power supply. This makes the power supply a critical component to the system. That's why when the power supply fails, your system will no longer operate.
What input devices are used in a Point of Sales terminal?
Bar-code scanner & Credit/debit card reader.
What devices need a device driver?
An example of a device driver would be the interface between the Windows Operating System and the computers Network Interface Card.
Device drivers are used to eliminate the need for the Operating System to know how to "talk" with a given device. The Operating System makes standard calls (called API calls) which are intercepted by the device driver, translated into something the device can understand and passed to the device.
Who is the world's second computer maker in the world?
This answer varies on a few things. Are we talking about computer manufacturers or software developers? Both play a big part of computers. Some of the worlds leading PC manufacturers are: HP, Asus, Toshiba, Dell, and Lenovo. As for software there are way to many to be named.
Is a webcam an input or an output devce?
A webcam is an input device because it is used to capture data such as images and videos and feed this information into a computer. Webcams are most commonly used as a form of visual communication but they can also be used to record videos and take pictures. Webcams are usually connected to a computer through a USB port or built-in port.
A webcam is a type of imaging device which means that it is used for capturing and processing data. It can be used for a variety of purposes such as video conferencing taking pictures and recording videos. Webcams are typically attached to laptops desktop computers or monitors. They can also be connected to other devices such as smartphones digital cameras and tablets.
Webcams have several components including a lens image sensor and a microphone. The lens focuses the image sensor on the subject that is being recorded. The image sensor captures the image and sends it to the computer. The microphone captures audio and sends it to the computer as well.

What is a USB to serial converter?
Most serial adapters can be found on computers and they connect the monitor/screen to the actual computer itself. A serial adapter may also be used to connect your television to your laptop. In this case, you would connect the usb part to your television port where it is marked USB and the serial adapter part to your computer.
Why does your computer over heat?
Could be several things, if it is a desktop be sure that it has enough space around the case to provide for good airflow, a couple of inches on the back and one side is usually enough. Check your vents for dust, if you see dust and other gunk get some compressed air in a can and blow it out. Open up your case and check for dust built up around the fan and heat sink (this looks like a series of metal fins) blow out with compressed air. Listen to your computer and see if the exhaust fans are kicking on. You normally have to wait a little while for them to start running, if they dont kick on replace them!
If you are using a laptop be sure it is sitting on a hard surface if you leave resting on your bed or couch it will resrict airflow to the fans, casuing it to overheat, also blow out vents with compressed air. Dont try and take it apart unless you know what you doing though!
If your computer has been overheating often your processor could have sustained damage. If you fix the overheating issue you may find that your p.c. still acts wacky. You might have to replace your processor, or even other componets depending on how hot it actually got!!

What part of the computer does the processing?
The central processing unit (CPU) is the part of a computer that processes data. In the past, the CPU itself used to take up a large cabinet that was full of many circuit boards. Nowadays, multiple CPUs fit inside a single chip, and that chip fits onto a single circuit board known as a motherboard.
What are the 4 main parts inside a computer?
Input storage processing output The above is almost correct. Actually, it's the closest I've seen to the correct answer. The question is actually 40+ years old and was asked of me in an engineering class back in 1968. Back then it was 'What are the 5 parts of a computer.' Storage is too vague. The answer here is memory. Technically s computer does NOT need storage, aka a hard drive or a floppy etc to be a computer. It needs: CPU (for processing commands) Input (from a keyboard, or a floppy, a hard drive etc to input both commands and data) Output ( to a monitor, a printer, magnetic tape, paper tape, punch cards etc) Memory ( the place an actual program and or data that the CPU uses MUST reside) The 5th item I alluded to is the Arithmetic Processor. The CPU proocesses the commands while the Arithmetic Processor manipulates the data to add, subtract, multiply and divide. In today's computers (post-1985) the CPU and the Arithmetic Processor are on the same chip. Previously, for those who remember the Z80 and the 8080 processors, for more "computing power" you could install an Aritmetic Processor to upgrade the PC and give the built-in arithemtic processor more capability.
How can you tell if your video card supports pixel shader version 1 or higher?
You need to be asking about your graphics card. A modem is used for a phone line connection, and therefore does nothing with pixel shading. You need to get a graphics card to do that.
What is the definition of peripheral?
A periphery is the outer limit of something, so peripheral relates to something on the edge. For computers that means the stuff that works with it but is not a part of it. Like a printer.
How many transistors does an computer have?
Anywhere from none to many billions, depending on the computer.
- vacuum tube computers had no transistors
- transistorized computers had a few thousand to a few hundred thousand transistors
- integrated circuit computers had a few tens of thousands to a few million transistors
- microprocessor computers have had a few thousand to many billions of transistors
What part of the computer directs the acitvites in the CPU?
The fastest components such as CPU and primary memory travel through the north bridge. Inside the actual CPU there are various caches. A modern Intel architecture (x86) CPU has an L1,L2 and L3 cache.
CPU cache is important as it reduces the time needed to access the primary memory. Usually L1 is purely for instructions, and L2 can store small amounts of data. And L3 works with both of them..
