Can you run mac OS X in Intel core i3?
Intel's Core i3 is a processor and so you will not be able to install anything into it. You will need to add other components to the processor to make a computer. Only computers made by Apple can have Mac OS X installed on them. Apple makes computers that use Intel's Core i3.
Why computer hardware is necessary?
hi luckysmey
i am konw that the importance thing in computer is mother board because everything we connect to mother board so mother board is the most importance componant.
bye! friend na
The importance of computer hardware is includes different parts from which the computer build. it is a computer equipment in such as system unit, power supply, memory, central processing unit, motherboard, hardisk drive, monitor, keyboard adn mouse.
Why is it useful to compress digital audio?
To lower the original wide dynamics. Scroll down to related links and look at "Loudness war - Wikipedia".
How does BIOS communicate errors?
The bios reports errors on the start-up screen. Simply white on black. It reports any failures to start up correctly, for example if an operating system is not found, or a vital component is not functioning.
If the screen memory or basic video cannot be accessed, the error can be signalled by a series of beeps from the onboard sounder. The exact meanings of the beeps, will have to be looked up in the motherboard instructions.
What is the part of the computer that contains the hard drive?
The hard drive is usually installed inside the computer case. Some refer to this as "the box" or "the system unit."
Some even refer to this part of the computer incorrectly as the CPU. That is due to misunderstandings and in some cases, carryovers from the old days. The central processing unit was not a single chip like it is now, but a collection of many chips and transistors which spanned multiple circuit boards. So in the early days, all those components collectively made up the CPU. Now, the CPU is a single chip, and most of the other components are included on the motherboard, and they all make up the system unit which is together inside the case.
What does the compact disc do?
A compact disc, first marketed in 1983, is a sound carrier that is played by a laser beam that reads the code in the disc. A compact disc player is a machine that spins the disc, shines a laser on it, and sends the resulting electrical signal to an amplifer, which sends it to speakers.
Which type of memory holds the basic operating system commands?
ROM does.
It's a type of non-volatile memory burned on a chip and usually soldered on the motherboard that the CPU fetches instructions from.
Usually the engineers will map addressable memory on to the CPU's address space, one being BIOS instructions, and the CPU will take those instructions.
As it loads a bootloader from another non-volatile storage device, like Windows on the first sector of a hard disk drive, BIOS the ROM memory willtransfer the first instructionto the processor's Instruction Pointer, and the Windows bootloader will keep issuing instruction, ultimately and effectively (most of the time) loading your operating system, device drivers, controlling the computer's memory, etc.
What is cache hit and cache miss?
Type your answer here... in cache memory when the CPU refer to the memory and find the word in cache it is said to be hit or produced.......
if the word is not found in cache it is in main memory it counts as a miss
How do you install new hardware?
You will shutdown the computer, and make sure that it is unplugged. Remove the sides of your case to reveal the guts. Plug in your new hardware, make sure it's fit snug and you have all mounting screws in, replace the sides of case and power on the machine. If you have a drivers CD that came with the new piece of hardware, insert into CD-ROM drive and install them.
There 3072 KB in 3 MB. One megabyte is equal to 1024 kilobytes. Thus, 1024 * 3 = 3072.
It's worth noting that there is a difference between "KB" and "kb". The acronym "kb" is short for kilobites, while KB is short for kilobytes. There are 8 bits in one byte. In computer science, these two terms are used to measure information.
What are human memory has three components?
The three stages are sensory memory, short-term memory, and long-term memory.
Difference between coprocessors and main processor?
A coprocessor provides auxiliary functions or features that the main processor does not have. These might include floating point support or hardware encryption. A coprocessor is generally not usable without its main processor, whereas a processor may function in a crippled or less powerful form without a coprocessor. An example of a processor and a coprocessor pair would be the 80386 and the 80387.
What are hardware peripherals?
Peripheral Hardware is hardware such as Mice, Keyboards, monitors.
Anything the computer doesn't require to run.
What are examples of analog devices?
Examples of analog devices are:
- A television
- blender
- generator
- electric motor
The card provides a port for a network cable to connect the PC to a network?
Lan Card provides a port for a network cable to connect the pc to a network..
LAN : Local area network

Ethernet Card and Network Card
SIMM (Single Inline Memory Module), is a form of RAM (Random Access Memory) It is a ram chip with memory chips on one side. A DIMM (Dual Inline Memory Module) is like a SIMM, but has memory chips on both sides.
What is the native resolution of a standard VGA card?
VGA (Video Graphics Array) supports up to 640 x 480, which is a 4:3 ratio between horizontal pixels and vertical pixels. Page 328, CompTIA A+ Guide to Hardware Managing, Maintaining, and Troubleshooting, Fourth Ed.
How do you connect a telephone line to Magic Jack?
MagicJack's contact information:
MagicJack LP/Ymax Corp, 5700 Georgia Ave., Palm Beach, FL 33405
Telephone: 561-586-3380
Fax: 561-586-2328
Tried faxing to no avail. Called landline and they indicated they could not froward fax to Magicjack as they were only a domain provider. They indicated that if I forwarded a registered letter they would forward it to Magicjack.
This Magicjack is totally reprehensible when it comes to customer service. Once they have your money all your problems are directed off shore through their online assistance and they are useless.
Save your money because if you have a problem it is a ghost company.
How much is a kilobyte and megabyte?
1000 kilobytes are in a megabyte and 1000 megabytes are in a gigabyte.
These are the storage industry standards.
However, megabytes as displayed by an operating system are actually measured in binary form, thus 1,024 kilobytes are in one megabyte, and 1,024 megabytes are in a gigabyte.
There are 1,048,576 bytes in a megabyte, and 1,0458,576 kilobytes in a gigabyte.
This is one reason why your operating system will claim that there is less memory on your hard drive than what the manufacturer claims.
