Computer Hardware

Depending on the make and model, there is usually somewhere on the motherboard, a jumper which resets the BIOS.

Sometimes it is a jumper plug attached to pins, on others it is two pads on the circuit board, which you short out with a wire or tips of tweezers.

They usually put them where you can get at them without too much dismantling.

A good place to look is under the memory modules.

It may be marked cryptically on the board, as something like 'rst'

It will reset everything back to factory settings, even the clock, but it should then boot up OK and you can then reconfigure it.

on a laptop it is on either the left or right side. The sign that indicates that is is the port looks like a dot with a cord that branches off into three, two of them are dots and the middle one is an arrow.

Thumb drive, or pen drive are all types of memory stick.

USB memory sticks are used to copy, store, or transfer files on a computer.

They replace the use of floppy disks.

input devices are those devices through which we give input to our device or system,...i/e keyboard, mouse, video cam, scanner or e.t.c

Multi-Function Printer

thousands of dollars while a mainframe often has the components to build many computers with multiple processors and hard drives and even sometimes multiple of these linked together to complete the system. if your not a really large buissnes like IBM or such chances are you can live well with a home server from Microsoft or their small buissnes server.

A combination of hardware and software is typically referred to as a computer system. For a computer system to be a complete system it must have several specific components. For hardware, it requires a processor, an input device (such as a keyboard or mouse), and an output device (such as a monitor or printer). For software, a computer must have an operating system of some type, which is called firmware in some devices. Note that a touchscreen monitor can serve as both an input and output device.

Control Unit is an hardware eye of computer.

Well, as you might already know that CPU(Central Processor Unit) is termed as brain of computer.

CPU consists of three parts as follows

1. ALU(Arithmetic and Logic Unit)

2. Memory

3. CU(Control Unit)

Job of control unit is to monitor all activities and make sure that everybody is doing what they are supposed to do.

Laptops do not have a VGA or PCI-E x16 slot so, no. Most have integrated graphics. Sometimes you can send it into the manufacturer to get a better integrated graphics chip installed, but you're probably better off buying a new laptop as the aforementioned process can be excruciatingly expensive and you'll be out of a laptop for a while.

Ok, you can use an ExpressCard to PCI-E converter device, which does exist,and then install whatever PCI-E card you want on that. That way it would use an external display, but it would work.

Add RAM!

Up to the limit that your motherboard can support.

Open the case, remove the old, smaller memory card, plug in a larger memory card that is compatible with the OLD memory card.

You add more RAM.

The motherboard on your computer has sockets to take RAM. There are different types of RAM so you need to get the right version. There is a limit to the size of the RAM that your Motherboard can support, and that varies from machine to machine.

If you don't know the details take it to a computer shop and get them to upgrade it for you. They'll be able to tell you what type it takes and how much you can put in.

USB, which is an acronym for Universal Serial Bus, has established an industry standard for connectivity It eliminates the need for multiple ports for input and output devices, and also bridges the gap between parallel, which was used to transfer data for storage or production and serial, which would link the computer to human interactivity devices like the mouse or the keyboard.

To provide personal computing power to individual users.

CMOS RAM is Powered by a trickle of electricity from a small battery located on the motherboard or computer case, usually close to the firmware chip, so that when the computer is off, CMOS RAM still retains it's data.

Its not special, standard. Hard drive, CD ROM, on older computers.

A specification for extending the internal circuitry bus that transmits data from one part of a computer to another by inserting circuit boards. It allows the expansion of a computer by inserting printed circuit boards, or expansion boards, into sockets expansion slots inside the PCI bus. Full form: peripheral component interconnect.

I have an app called Zimly a well featured media player app, which helps me to connect my PC to TV. I use Zimly to transfer my media files from my PC to my smartphone, or to my TV using chromecast. With the help of Zimly I am able to watch my favorite videos on the big screen.

Try Zimly to connect your PC to your TV.

A heat sink in a computer is a large piece of metle that is attachesd to electronic components(like the processor, hard drive etc.) It obsorbs and disipates waste heat from the devices so that they don't over heat.

Provided that the air inside the computer case is hotter than the temperature in the room, then basically: yes, the hot air from inside the case is replaced by cooler air from the room. However the fan only moves around the air it doesn't change the air temperature so make sure you have some good AC.

A: Even if the same hot air if allow to flow on an object it will cool it. That is the answer.

But if your PC is in front of AC for more than 3 hours, Your computer will be over cooled and this is again harm to the Computer.

A computer case needs to be large enough to house all the hardware you want to put in. Other than that, the sky is the limit.

Pv4 uses 32-bit (four-byte) addresses. which limits the address space to 4,294,967,296 (232) possible unique addresses. However, some are reserved for special purposes such as private networks (~18 million addresses) or multicast addresses (~270 million addresses). This reduces the number of addresses that can potentially be allocated for routing on the public Internet. As addresses are being incrementally delegated to end users, an IPv4 address shortage has been developing.

A device which changes one form of energy to another is called a transducer, this includes changing electric energy into mechanical pressure waves, in short, sound! the most common transducer for playing sound is a speaker which uses the properties of electromagnetism to create a physical sound pressure wave.

Computers transfer everything into a simple 2-digit code. The values are either 1 or O. This is the Base 2 number system. The Base 2 Numbers is easy for computers to handle because electricity can be On or Off. The electrical current flips a magnet-type device in its memory so that it is either in a 0 state or a 1 state. This is how the memory stores anything no matter how complext the data is. Any number in the Base 10 which we use(hey we have 10 fingers) can be converted into the Base 2 numbers. The computer does this and then operates by adding or multiplying in the Base 2 and then it converts it back to Base 10 for you to understand. Counting in Base 2: 0..... 1..... 10..... 11..... 100..... 101..... 110..... 111 ..... 1000 ..... 1001 ..... 1010 ..... 1011 ..... 1100 1 ..... 2 ..... 3 ..... 4..... 5..... 6..... 7..... 8..... 9..... 10..... 11..... 12 ..... 13 I hope that is right.

on all the new computers like the mac book air and stuff like that but to get that software you will have to go to a place like PC world or specialists in computers, laptops and phones and probably you will have to either download it or have it on a chip or something.
