What is an AGP slot of the motherboard used to install what?
As it's name implies, AGP (Accelerated Graphics Port) slots are commonly used for high-performance video cards. Other devices using the AGP slot are possible, but rare. It could also be used for sound cards, extra USB card...
What is an USB mass stoarge device?
This is a title which often appears in the Windows operating system that describes a class of device . It most often appears in the lower right corner of the screen when you connect a flash drive, mp3 player, or memory card to your computer. Basically, a "USB mass storage device" is a "Device" which connects through a "USB" port and "stores massive" amounts of memory.
What is difference between BIOS and POST?
the BIOS is a series of settings for your motherboard where the POST is a process of checking the components before the computer boots into your operating system (windows, linux, etc.)
How does a computer represent numbers using bits?
Many computer systems (though not all) represent numbers internally in base two, by using large numbers of heavily miniaturized devices called bistables.
Bistables really are a class of devices, like "cars" for instance. Various technologies will implement bistables in various ways, but like "cars", they will all implement some basic common functionality. In the case of the bistable this basic functionality is the fact that they can only have one of two states, at any one time: "on" and "off".
The "on" state of a bistable represents a binary "1" and the "off" state represents a binary "0". Thus, the decimal number 3 (binary 11) for example can be represented by two bistables, each of them in their "on" state.
Because bistables have two possible states, they can only be used to represent base two numbers for which only two possible digits (1 and 0) are needed. Therefore computers are said to operate in base two.
However, any number can be converted from any base to any base, so any decimal number one can think of can also be stored by a computer in base two, with no disadvantage.
Any content that can be represented numerically can also be represented by binary numbers and therefore computers are able to employ various quantities of bistables to represent all sorts of contents, from images to text to software. hello people, kyjc
How are input devices connected to the computer?
A device which connects to the computer is called a "peripheral."
What type of device that when installed is not listed in BIOS setup or Device Manager?
Neither, BIOS does not list device drivers at all.
What if your mac beeps 3 times at startup what does this indicate?
When it starts up a Mac runs tests to check the hardware. It beeps to indicate where a problem may occur. 3 beeps indicates a problem with the memory. It is usually advisable to have an Apple service shop have a look at any Mac that is beeping at startup.
1 megabyte equals to how many bits?
Finishing up with some math, I got somewhere around 1048576 bits in 1 single megabit.
What are examples of automatic input device?
If I understand this question correctly, then automatic input (assuming that there are no software restraints such as "permissions") can also be said as "continuous" input. That can include microphones, webcams, pressure sensors and heat sensors.
How much should I earn per hour of computer tech support?
For the profession of the computer tech support you should be earning at least eight to ten dollars an hour. This all also depend on the state economy you live in the minimum wages and also they sometimes look at the amount of experience you have in that particular field. There are many factors that can increase or decrease you expected wage.
How can you activate number lock on a Toshiba Satellite laptop which has no numlock key?
Well first of all you can't deactivate it because it won't be on if you don't have a numlock button. Anyways, my Toshiba (might not be the same laptop, I'm not sure which one i have) but I've read if you go to the onscreen keyboard (start menu>programs>accessibility>Onscreen keyboard) it has a numlock button on it
How does system clock speed affect a computer speed?
There are several numbers and terms here that must be understood before that question can be answered. Many computer processors use a front side bus to communicate with the north bridge and RAM. The speed of that bus determines how quickly the CPU can read and write to memory as well as other peripherals. For ease of synchronizing those systems, many CPUs will set their Core processor speed to a multiple of that FSB. The actual "speed" of your CPU will be determined by the FSB * multiplier, but most CPUs will actually execute several instructions per core clock "tick." It's very difficult to determine how fast a computer will be compared to another one based solely on the clock speeds.
What color is the ground wire in a computer?
Inside the computer, the various ground wires are black. Computers use direct current inside. The wiring color differs from AC, where both red and black wires are hot wires, white is neutral, and green or bare is ground. In a computer, the red and yellow wires are positive wires of different voltages.
What are the sublayers of the data link layer as defined in the IEEE 802 standards?
The sublayer below it is Media Access Control (MAC). Sometimes this refers to the sublayer that determines who is allowed to access the media at any one time (usually CSMA/CD). Other times it refers to a frame structure with MAC addresses inside.
There are generally two forms of media access control: distributed and centralized. Both of these may be compared to communication between people. In a network made up of people speaking, i.e. a conversation, we look for clues from our fellow talkers to see if any of them appear to be about to speak. If two people speak at the same time, they will back off and begin a long and elaborate game of saying "no, you first".
The Media Access Control sublayer also determines where one frame of data ends and the next one starts -- frame synchronization. There are four means of frame synchronization: time based, character counting, byte stuffing and bit stuffing.
- The time based approach simply puts a specified amount of time between frames. The major drawback of this is that new gaps can be introduced or old gaps can be lost due to external influences.
- Character counting simply notes the count of remaining characters in the frame's header. This method, however, is easily disturbed if this field gets faulty in some way, thus making it hard to keep up synchronization.
- Byte stuffing precedes the frame with a special byte sequence such as DLE STX and succeeds it with DLE ETX. Appearances of DLE (byte value 0x10) has to be escaped with another DLE. The start and stop marks are detected at the receiver and removed as well as the inserted DLE characters.
- Similarly, bit stuffing replaces these start and end marks with flag consisting of a special bit pattern (e.g. a 0, six 1 bits and a 0). Occurrences of this bit pattern in the data to be transmitted is avoided by inserting a bit. To use the example where the flag is 01111110, a 0 is inserted after 5 consecutive 1's in the data stream. The flags and the inserted 0's are removed at the receiving end. This makes for arbitrary long frames and easy synchronization for the recipient. Note that this stuffed bit is added even if the following data bit is 0, which could not be mistaken for a sync sequence, so that the receiver can unambiguously distinguish stuffed bits from normal bits.
How much on average does a motherboard cost?
You can buy a used one, but that wouldn't be very smart. It's better to simply buy a new computer, but a motherboard is about $200 - $300 .
Is crt an output or input device?
Most CRTs were used in output devices.
However some CRTs were used in input devices as flying spot scanners to scan microfilm documents into the computer. This function has generally been replaced by LASER scanners, which can be used on opaque documents that the CRT could not scan.
What does PC input on a tv do?
on most new televisions it will have a rgb port for rgb cables which means you need a cable with 2 RGB sides and connect one to the computer and the other to the port on the back of the television.
How many songs will a 2GB flash drive holds?
anywhere from 500-1000 depending on format and song length
apple ipod format is about 250/gb
windows zune is about 500/gb
these ratings are based off a 3-4min song average
What is a cooling unit computer wise?
There are two main types: Air
Water
Air cooling just uses fans to dissipate heat.
Water cooling tends to be used in top-end custom built PC's and uses water to remove heat from components such as the processor RAM etc
universal automatic computer

Is it possible to make a desktop into a laptop?
To some degree, yes. It is possible in the sense that you can put a motherboard in a portable case, connect it to battery power, use smaller drives, etc... The main issues in doing so are heat dissipation and the power system / power management. Heat dissipation is the ability to remove heat from the system so that it does not overheat, a greater challenge in a small case. The problem with power is first that you will probably not be able find a portable power supply that can automatically switch from AC power to batteries. Even if you do, monitoring it may not be handled transparently by the operating system (ie a battery icon in the system tray), requiring additional software.
What is the function of RJ45 connector?
RJ45 is the standard 8P8C telecommunications connector commonly found in computer networks such as Ethernet. RJ45 specifies both the plug and the socket. Connections are typically formed using twisted pair cabling, predominantly Category 5 (CAT5).
Ethernet cables may be configured as patch cables or as crossover cables. These two configurations are standardised in TIA/EIA-568 and ISO/IEC 11801. Patch cables are used to connect two different devices, such as when connecting a computer to a network switch or hub. Patch cables use the T568B scheme to terminate both endpoints. T568B is also used to terminate socket-to-socket endpoints and adaptors. Crossover cables are used to connect devices of the same type, such as when connecting one computer directly to another, and use the T568A scheme on one end and T568B on the other.
