Most common and slowest expansion bus?
As of right now, the fastest expansion bus found in a standard PC is a PCI-E or often seen as PCIe (PCI-E or PCIe stands for Peripheral Component Interconnect Express)
Installing a PCIe card into your PC may be done only if the motherboards expansion slot will fit it. PCIe cards can fit into larger slots, but not smaller slots (obviously).
A port that transmits data eight bits at a time?
A port that handles more than one data bit at a time is a parallel port. The most common example is the printerport (LPT) found on most older computers. The port is designed to transmit and receive 8 bits at a time.
Parallel ports are less common on modern computers as the USB port has now replaced it for the majority of applications.
Is a scanner and input device?
A Scanner is a device that allows you to scan paper documents to your computer. The file will be saved somewhere in your computer, usually in your My Documents folder. Today, scanners are connected to printers, and they can also copy documents placed on the scanner bay if desired.
How do you turn a computer screen upside down?
Press Ctrl, Alt, up arrow but this only works on Windows Vista.
What are the two current speeds of RIMMs?
RIMMs operate at speeds of 600 MHZ (PC600) or 800 MHz (PC800). All installed RIMMs must operate at the same speed, and have the same ECC or non-ECC rating. The operating speed is different than the data path size. RIMMs are avilable in 16- or 32-bit data path.
What must be true before motherboard?
A motherboard must be modified to accept a particular type of memory, especially when dealing with multi-channel memory. On most motherboards, several types of modes can be configured to run at the same time. It is best to read the manual that came with your motherboard to find out how to correctly configure yours.
What are the examples of computing devices?
software is a general term for programs that control the computer system.
there are two types of software.
programs that allow the hardware to run properly, e.g.operating system-system software:
application software:programs that allow the user to do specific tasks, e.g.
spreadsheets.
After replacing CMOS battery what will you do?
Once the battery is replaced turn on the computer and resetting the CMOS values to the defaults. After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action.
If after following all the above steps you continue to experience the same error when your computer starts or your computer is still unable to keep the stored values it's likely that you're experiencing a more serious issues. Most likely causes are bad power supply or bad motherboard.
How many megabytes is a 10 mega pixel?
the 14mp camera has 1.4 times better quality than the 10mp one
How do you remove the hard drive from a Gateway M305CRV Laptop?
Shut down the laptop. Turn over the laptop and you will find a small panel with a Hard drive sign with 2 screws on the panel cover. Unscrew the cover carefully and pull out the HD very carefully. It's very simple.
Describe the physical and social conditions under which a computer system perform best?
computer need a good cold area for for it to function at is best
How do you turn on laptop without opening lid?
If your laptop has a power button which can be accessed without opening the lid, just press the button. However most laptops these days have the power button under the lid (to keep you from accidentally turning it on in the bag) in which case, youll just have to open the lid.
i think you mean "can you put pictures ON a cd-r" and the answer is yes, of course just not a lot. get a USB DRIVE a 5 dollar one holds more pictures, and is re-writable, and soooo easy to use, you dont have to worry about burning.
Can a USB port burn out a device?
I recently purchased a Toshiba external hard drive to move some stuff from my daughters tiny 20G HD on her Inspirion 2650. This is a USB 2 device, and I assumed the USB ports on the computer were also. I guess not. I got a message from XP saying the ports couldn't provide enough power to the device. I saw the drive had a socket for a DC power supply, so I plugged in the appropriate voltage wall wart. I immediately smelled burning circuitry, so I unplugged it. The USB ports smell like a burned electrical device and they no longer work when I plug in the USB mouse or a memory stick. I'm going to have to pull the MB and see if I can find a fuse to replace. Anyone done this?
You have burned the USB ports, and i doubt theres a fuse for this.you plugged the AC adapter in so it was getting its full voltage from that plus the extra voltage from your USB and you have fried the circuitry.
How does an Ethernet switch work?
Ethernet switches, both unmanaged and managed, avoid collisions by routing the messages in an Ethernet network to only the intended devices. When a switch receives an Ethernet message (packet), it reads the address of the device for which the message is intended, and then transmits the message out of only the port to which that device is connected (even if it is connected through several other switches).
When the switch gets the first bit of information from the first device, such as your computer, it reads the MAC address of that device. The MAC address is the media access control number. This number is an ID number that is assigned to most network adapters and is preset by the manufacturer. Once this number is read, it is recorded in memory by the switch. Next, the switch attempts to look for any other devices on the network by sending out packet requests of information. Once another device gets this packet, it sends out a signal to the switch to acknowledge the request. Now the MAC address of this device is recorded. Each time these packets are sent, the information is "time stamped." The switch then works to filter this information that is communicated among all of the devices. The switch has enough memory to retain this information.
Industrial applications of Ethernet (called industrial Ethernet) require special Ethernet switches that have industrial ratings for noise immunity, shock, vibration and temperature in a wide range of form factors with multiple options for copper and fiber connectivity. See link below for examples of industrial Ethernet Switches from Phoenix Contact.
What is a RFID scanner used for?
3M ESPE company - manufacturer of dental products - uses RFID technology in their mixing machine Pentamix 3. It helps to recognize high quality 3M ESPE impression materials and allow to mix them in double speed than competetive impression materials, which quality is lower or not clinically proven. The reason of RFID sensors used is to ensure safe and comfortable use of the machine.
What is another name for a video card?
Another name for a Graphics card is:
Video Card
Expansion Card
or
Video Acceleration Card
Is a speed carmera a input devices?
A speed camera is not classified as an input device; rather, it is considered an automated enforcement tool used by law enforcement to monitor and record the speed of vehicles. Input devices typically refer to hardware that allows users to provide data or control signals to a computer, such as keyboards or mice. Speed cameras capture data (the speed of vehicles) but do not serve the primary function of inputting data for user interaction.
What is the function of front side bus?
The front side bus formerly connected the Northbridge Controller to the CPU (a way of communication) it still has the same communication, but it is not called FSB, it is called a HyperTransport Bus.
What type of RAID volume is used for fault tolerance and only requires two drives?
RAID 1 is mirroring without parity or striping. It requires a minimum number of two drives and has a fault tolerance of one.
RAID 1 works by writing data to both drives, thereby producing a mirrored set. When the read is requested, it is serviced by the drive that has the lowest seek time plus rotational latency.
An example of this set-up is two 1TB drives in RAID 1 that have a combined total of 2TB of storage, but because they are in RAID 1, the effective storage space is 1TB as data is mirrored on both drives. It is effectively a real-time back-up system. If one drive fails, data is not lost.
