The original price of a computer was reduced by 225 dollars The new discounted price is 1274?
p-225=1274
What can you do to stop a computer from repeatedly restarting in a continuous loop?
Check if any capacitors are leaking on the motherboard. My company services Acer computers and we had a problem where multiple computers were shutting down and restarting. The capacitors were leaking and couldn't hold a charge causing the reboot. The top of the caps are suppose to be flat, if you see a bulge at the top of the caps or stuff leaking out of caps, there's the problem.
Try to clean your registry, a corrupt registry can also be the reason of computer shutting down.
Answer-- 1. Click the Start button, right-click My Computer, click Properties, click the Advanced tab, and then click Settings under Startup and Recovery.
2. Under System Failure, view the Automatically restart check box. If the Automatically restart check box is selected, Windows automatically restarts if the computer stops unexpectedly.
Have you tried the system file checker? I'm sure you know how, but just in case: Insert the XP CD in the CD-ROM drive: Start >> Run >> type: sfc /scannow.
3 ways computers are being used in the finance field?
Three of the most common things computers are used for in the finance field are:
- Conducting analyses
- Executing transactions
- Communicating
What is the main technology used to connect computers to devices?
The main technology to connect computers (also called nodes) to any device such as a router, switch, or another computer is the Ethernet Standard. The Institute of Electrical and Electronics Engineers (IEEE) 802.3 is the standard for connecting computers using a physical connection. The IEEE 802.11 standard is used for Wireless Connections also known as Wi-Fi,
What is MB in computer science?
MB stands for Mega Bytes. It is a unit of memory.
1 MB = 1024 kB (kB stands for kilo bytes)
Note: Do not confuse MB with Mb. Mb stands for Mega Bits.
What things must a good computer have?
It depends on what operating system you want to use. For example, the 32 bit version of Windows 7 needs at least 1GB of ram, 16 gb of free hard drive space, and a 1 ghz or better processor. If you search the wiki article of a operating system it will tell you the minimum requirements.
Where can I inquire anything about computer technology school these days?
Computer technology colleges offer the solid education you need to really understand how computers and computer systems work. Computer technology school train you how to install, repair, and maintain computer equipment, and how to install and manage computer networks. If you love working with computers, one of the many excellent computer technology programs is perfect for you!
How many word document pages will fit in a MB?
The number of megabytes on a word document depends on how much text, pictures, or other objects are in the document. Images take up more space then the text.
What determines the speed of a laptop?
There are several factors that are all involved in the speed (or lack thereof) of your computer. To simplify, the major components that directly affect the speed of your computer are: * Processor speed * Bus speed (communication between the motherboard and the processor) * Memory speed/quantity * Hard drive speed There are other items that can have an impact on the speed as well, such as how many applications are running in the background, and what services are running.
What does the power supply of a computer do?
- A power supply's job is to convert an Alternating Current (AC) signal coming from your wall outlet into a usable Direct Current (DC) signal. Simply stated, this process is done by stepping down the input voltage level with a transformer and then rectifying it to convert to DC. Once the DC signal is generated it is used to power all the devices and components of your system. In order to distribute the signal around to every component, many internal or external splitters can be attached to satisfy the number of connected devices. Usually a preset number of leads are provided by manufacturers to make this splitting procedure simple or even unneeded to the end user (as proper voltage values must adhere to specifications). From there, voltage regulation (often in the way of capacitors) is used to prevent your power supply from outputting too much or too little power. This protective mechanism is often called over current protection, over voltage protection, or over power protection. It is always important to ensure that your power supply has built-in regulation capabilities or spikes / sags due to fluctuations from the supply could damage your components. Alternatively, connecting your power supply to an Uninterruptible Power Supply (UPS) unit can greatly eliminate any potential harm due to external conditions on the unit.
- For computers the power supply is most responsible for providing power to the motherboard, your hard drive, CD drives, expansion cards, etc. In most cases, a single PSU unit (as opposed to a redundant power supply setup where multiple PSUs are cascaded in case one fails) is responsible for powering all parts internal to the system. Some external devices such as keyboards, mice, and external drives may also draw power either directly or indirectly from the power supply. This makes the power supply a critical component to the system. That's why when the power supply fails, your system will no longer operate.
What input devices are used in a Point of Sales terminal?
Bar-code scanner & Credit/debit card reader.
To computer technicians UPS stands for what?
Uninterruptible Power Supply. Its not a component of your computer rather a battery backup surge protector to keep your computer (or anything else for that matter) running in the event of a power outage.
What does the CPU fan unit do in a computer?
The fan unit helps keep the critical components of the computer cool to prevent overheating (i.e. processor, hard drive, motherboard, etc). The processor is especially susceptible to overheating and can actually melt a little if it gets too hot, ruining the processor and the entire computer.
Which hardware components does a computer require?
Here's a really simplified concept of the different parts of a typical desktop computer you might find in someone's house, organized in no real order:
input (mouse/keyboard)
output (monitor/speakers)
case (to house the hardware, to include a power button, etc)
processor (example: a 3.2GHz Intel Core 2 Duo "CPU")
memory (ram: i.e, 2GB of ram, a cache to keep info used in currently-happening tasks)
storage (a 320gb hard drive, a floppy/cd/dvd drive - something that has long-term data)
motherboard (mounted on the wall of the case, all hardware connects to this)
sound card (might be built-in to your motherboard, plug speakers into it for sound)
video card (might be built-in to your motherboard, plug monitor into it for visuals
power supply (gets power from wall outlet, precisely routes it to parts)
cooling system (might be a lot of fans in your case, maybe there is a liquid cooling, etc)
How does one check the performance of their computer cpu?
Get something like Speedfan (can be found in MPC CD's) or MotherBoard Monitor (MBM for short), although, MBM requires a bit more manual setup, I recommend Speedfan for ease of use, and quick autodetect feature for thermal sensors.
Where can one purchase a boot brush?
There are many places on the internet that sell boot scrapers. Places like Amazon, Sears, Ebay, and ZORO should have the times that you are looking for.
What is a main characteristic associated with desktop computers as compared to notebooks?
* Much cheaper components - desktop components don't have to be as small, so they don't have to be as expensive. * They can last many years - It's not unusual for a desktop to last for 10 years, if cared for. Most individual components can be easily replaced when they go bad in a desktop, but a laptop owner can encounter situations where expensive professional repair services or a full computer replacement are needed.
