You want only computer hardware knowdge?
Hardware for a wireless network..you need a router and a PC and some wiring. that's it
What does the IO unit of the processor do?
The input/output unit links the microprocessor to the rest of the circuitry of the computer, passing along program instructions and data to the registers of the control unit and arithmetic/logic unit. The I/O unit matches the signal levels and timing of the microprocessor's internal solid-state circuitry to the requirements of the other components inside the computer. The internal circuits of a microprocessor, for example, are designed to be stingy with electricity so that they can operate faster and cooler. These delicate internal circuits cannot handle the higher currents needed to link to external components. Consequently, each signal leaving the microprocessor goes through a signal buffer in the I/O unit that boosts its current capacity.
The input/output unit can be as simple as a few buffers, or it may involve many complex functions. In the latest Intel microprocessors used in some of the most powerful computers, the I/O unit includes cache memory and clock-doubling or -tripling logic to match the high operating speed of the microprocessor to slower external memory.
The microprocessors used in computers have two kinds of external connections to their input/output units: those connections that indicate the address of memory locations to or from which the microprocessor will send or receive data or instructions, and those connections that convey the meaning of the data or instructions. The former is called the address bus of the microprocessor; the latter, the data bus.
The number of bits in the data bus of a microprocessor directly influences how quickly it can move information. The more bits that a chip can use at a time, the faster it is. The first microprocessors had data buses only four bits wide. Pentium chips use a 32-bit data bus, as do the related Athlon, Celeron, and Duron chips. Itanium and Opteron chips have 64-bit data buses.
The number of bits available on the address bus influences how much memory a microprocessor can address. A microprocessor with 16 address lines, for example, can directly work with 216 addresses; that's 65,536 (or 64K) different memory locations. The different microprocessors used in various computers span a range of address bus widths from 32 to 64 or more bits.
The range of bit addresses used by a microprocessor and the physical number of address lines of the chip no longer correspond. That's because people and microprocessors look at memory differently. Although people tend to think of memory in terms of bytes, each comprising eight bits, microprocessors now deal in larger chunks of data, corresponding to the number of bits in their data buses. For example, a Pentium chip chews into data 32 bits at a time, so it doesn't need to look to individual bytes. It swallows them four at a time. Chipmakers consequently omit the address lines needed to distinguish chunks of memory smaller than their data buses. This bit of frugality saves the number of connections the chip needs to make with the computer's circuitry, an issue that becomes important once you see (as you will later) that the modern microprocessor requires several hundred external connections-each prone to failure.

What are four types of compact disk?
Four Types of Compact Disks are: CD-R, CD-RW, DVD-R, DVD-RW, CD ROM. (Well theres five).
Edit:
A compact disc is a CD. Therefore a DVD is not a compact disc. DVD is digital video disc.
CD-ROM is also a piece of hardware. Not a physical disc.
There are only 3 types of CD's. They are
- CD (Just the disc)
- CD-R (Recordable CD. You can copy things to it ONCE)
- CD-RW (Rewritable Disc. This is a CD that you can re-write over data currently on it.)
For more info Google search "types of cds".
It's 2 Kilobytes, or 2048 bytes. A Kilobyte is a measure of storage or computer memory. Computers store data as a series of 1s and 0s (on or offs) and this is called binary. Each 1 or 0 is called a "bit" which is short for "binary-digit". 1 byte = 8 bits 1024 bytes = 1 KB
Can you upload developed pictures on your computer with a scanner?
Yes, you can scan prints and, with a proper holder, negatives as well. The negatives will have to be reversed with editing software once they are on the computer. Picasa 3 and FastStone Image Viewer will do it, and both are free.

What does Analog power saving mode mean on your computer?
what does and analog computer do? Analog power saving, which can be activated by going to "Power Options" on your control panel, is a simple, manual way to save electricity that your computer uses. It allows you basically to pick what and when you want something to be inactive on your hard drive. This is normally done automatically. If you have problems with the new settings, just change it to default.
What kind of connector does a legacy serial port use?
The legacy serial port is a 9-pin DB connector. The 15-pin one is mever mentioned in chapter 18 of the A+ managing and troubleshooting pc's textbook. 3rd edition.
Why does your TV say signal out of range when you connect your PC?
All television signals are generated line by line to create a complete frame and the frames are refreshed continually. The lines and frames are repeated at a certain frequency. In the case of a television signal, the fields, or frames, are running at 59.94Hz or 50Hz. Computer displays frequently operate at higher field or frame rate. A message indicating the signal is out of range is almost certainly saying that the field rate is above the rate that the television will handle.
To rectify the problem, use the display settings dialog box in the control panel and adjust the frame rate. If it is set at 75Hz for example, try to lower it to 60 or 70Hz. It may also be necessary to change the resolution to an acceptable format. If the television has a native resolution of 1080 line, try to set the computer display resolution to 1920 x 1080 at 50 or 60Hz, That should offer the best quality display and avoids the need to resize the image to fit the screen.
There is often information on computer resolutions in the television's manual. It's worth taking the time to do some reading and that may save a lot of time experimenting.
Would you borrow your neighbor's wireless home network?
Depends: With or without permission? My neighbor uses our internet wirelessly, with our permission.
If you are trying to connect to a wireless network that is unsecured, your neighbor could very well be looking at everything that you do! Well, even if it is secured, they still could be.
But if you are using it without permission, just be careful not to get caught as some people pay for their bandwidth usage, and if you're upping their bill they may have it out for you!
The term USB modem refers today any type of data/fax/voice modem device which can be connected to a computer using USB, the term more commonly describes a specific portable usb device that looks similar to a usb flash drive & smaller in size. These small portable usb modems don't require a power source and can be plugged into any usb port on your pc. It can be disconnected from the computer without turning off the system. e.g.:Tata Photon Plus.
What is the best gaming graphics cards nowadays?
In 2015 the most powerful graphics cards are the GTX 980, GTX 980ti, and the Titan X from Nvidea. AMD has the Radeon 290, 290x, 390, and the 390x also.
What aligns heat-producing parts between the air intake vents and the power supply's exhaust..
Is it possible to create your own U3 usb drive by changing a drives firmware to the U3 firmware?
No, since U3 is hardware and software combined.
Why aren't my zipped files any smaller than they originally were?
Depends on the file type, some, especially downloaded files and executables (.EXE and .COM) files are already compressed, so therefore won't be smaller when you zip them.
You can combine zip files into a single zip file, but it doesn't make the file size a smaller total.
Where is the location of the USB port usually?
The USB port looks like a rectangle. Typically the USB port is located on the motherboard on the back of the desk top computer or a tower or possibly on the front of the computer depending on the brand and style of the computer. If it is a laptop, it may be located on either sides of the computer or on the back.
What are the environmental requirements for a computer?
There are no specific environmental requirements for a computer. Computers have been designed to work in a wide variety of environments, from the top of Mt. Everest to the inside of a car to the temperature and radiation extremes of outer space.
Can you use SDRAM and DDR interchangeably in a computer and does it really matter which one you use?
No, you can't use sd ram on a motherboard that specifies DDR memory and vice versa. It matters in terms of speed which type of memory you use, DDR is faster.
Is 1 gigabyte good for a computer?
If you mean as harddrive space then GOD NO! You will not be able to store most applications on a 1 gig harddrive.however if you mean 1 gigabyte of RAM then it is not too bad.
What is an Accelerated Graphics Port?
