Why is Boolean algebra used for combinational logic circuits?
Because it is a very efficient language for describing their operation as well as a tool to assist in design optimization (reducing the cost of the circuit when built).
What is the London eye used for?
It is an attraction used for sights at a very high altitude. You can see a lot of London when at it's high points.
What is the point and draw device?
Point and draw Devices. A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes.
A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer.
Examples:
- Mouse
- Joystick
- Pointing Stick
- Stylus
- Light pen
- Touch Screen
What is a computer when it is turned on and the operating system is being loaded?
A computer is loading data when it is turned on and the operating system is being loaded.
How many watt power inverter is required to run a 1hp 110v motor?
Need to know the running amp draw. Starting amps would be useful l too.
The average amp draw for a simple 1hp motor is about 7 amps, such as a fan motor. Ohms law says amps times voltage = watts, so 7 amp times 120v=840 watts. Consider that starting amperage is about 1-1/2 times running load, starting watts would be about 1200. You would need about a 1200 watt inverter to run that motor.
What is the recommended wattage capacity for a power supply for?
If you have a 500 watt power supply and you want to put in a new video card. On the video card's box it will tell you how much power it needs. If it requires less power then you don't need to worry. If it says it requires more, you'll need a bigger power supply with large wattage otherwise you'll kill your computer.
What innovation in computer technology was made possible by the use of integrated circuits?
Instead of punched cards, users interacted with their computers using keyboards, monitors, and operating systems.
What is computer operating speed?
Computer operating speed is generally the speed at which the CPU operates, known as the clock speed. It is expressed in Mega-Hertz or Giga-Hertz. For example a Pentium M processor running at 1.8 Gigahertz is being clocked internally at 1.8 GHz.
Difference between batch processing and time sharing?
In batch processing the tasks are performed in batches. In time sharing, the operating system shares the time between each task.
What is an expansion bay for a computer?
An expansion bay is a large slot typically located in the front of a desktop PC. Expansion bays are used for adding additional hard drives and optical drives to your computer. They can be used for other special devices as well.
What institutions are using univac and eniac computers?
none. none of these machines still operate. the last UNIVAC I was shut down in 1970. the ENIAC was shut down in late 1950s.
The Drag and Drop functionality of Windows operating system would help you do this. While doing so, hold the Ctrl Key on the keyboard until you reach the desired place on the screen.
How many bytes of memory is a 1Mx64 memory chip?
A 1Mx64-bit memory chip contains <1,048,576> , or <2^20> 64-bit Lwords. You could express this either in terms of MegaBits or MegaBytes. In Megabits, 64Mbits because 1Mx64 = 64Mbits and divide by 8 to get the answer in terms of bytes. You divide by 8 because there are 8 bits in 1 byte. So a 1Mx64-bit memory contains 8 Mbytes, or 64 Mbits. If the width had been 1Mx32-bit, you would have 32Mbits, and 4 Mbytes.
Who is likely to use a graphics tablet and why?
Graphics tablets are widely used in the creative industries by illustrators, architects, fashion designers, graphic designers and interior designers to name a few.
They are favoured for their accuracy, pressure response, ease of movement and technical abilities as opposed to a standard mouse.
Click file then click run ISO then click your game image and it'll start automatically.
How do you transfer MP3 files from your computer to your MP3 player?
It depends what type of MP3 player you have. If you have one that has a USB port built in just plug it in and transfer your files via windows media player 11. Or if it has a wired connector plug that in then plug in to the USB, this wire should have come with the product. If you have lost your cable, one can be bought on numerous online retailers, including local RadioShack's, CircuitCity's and Best Buy's. Just to name a Few.
What is a difficult order of operations problem?
Many expressions involve two or more operations. When simplifying such expressions, it is important to perform the operations in the following order:
1. Perform any operation(s) within group symbols, which are:
a. parentheses ( )
b. brackets [ ]
c. braces { }
d. fraction bar /
e. absolute-values bar | |
f. radical sign
2. Simplify all powers.
3. Multiply and divide in order from left to right.
4. Add and subtract in order from left to right.
If you don't follow this order of operations, you will find a wrong answer.

Why constant beep at PC start up and no video?
hardware trouble, that's your motherboard trying to tell you there's an error. when this happens you can either look up the error code or troubleshoot:fiddle with the insides (reseat ram, cards, ide connectors)remove everything that you possibly can from the motherboard(unplug all cards aside from video card, unplug hard drive, CD-ROM drives, DVD-drives, remove any usb/firewire devices that are plugged into PC)swap out parts (this is only really possible if you have spares)remove everything and put it back together
if this is happening and the PC has never worked before it would be likely that some part of the setup was DOA, like the memory, video card, motherboard, or CPU
WHAT ARE the ancient computing devices?
ancient as in the Chinese calculator that uses beads, or as in the first electronic computer, Eniac?
What is self dual logic function?
