Can a computer be left in freezing temperatures in a garage?
Yes, but there is a back up battery for some chips inside the computer. The freezing can cause this chip to die. Make sure you let the computer come back to room temperature before turning it on or the hard drive may break. I would suggest bringing it inside a day before you plan on using it. That will give it time to return to room temperature and for any condensation that formed during the thawing to evaporate.
What do you do if the Windows display freezes after startup and the power supply is really hot?
The display is probably freezing because the grafic card or processor is getting to hot. When this happened to me I had to install more fans in my computer case to help cool the system. R. > Check your power supply, It could be bad.
Where is the headlight power supply on a 97 Chevy Cavalier?
The headlight power supply in a 1997 Chevy Cavalier is typically located near the headlight assembly or the front of the engine bay. It is usually connected to the vehicle's fuse box or electrical system. You may need to consult the owner's manual or a repair guide for specific instructions on accessing and replacing the headlight power supply.
How important is computer hardware to the computer system?
That depends on what you plan on doing on the computer system, if you plan on running taxing programs, like games or graphic modeling programs, then computer hardware is extremely important, on the other hand if you are only intrested in surfing the internet and writing word documents then computer hardware is fairly unimportant.

Dual processing might mean multi-processing which means using more then one CPU core in order to run a system or program. By using many CPU's you can split the workload of many programs over independent CPU's and reduce the workload. Or speed up the operation of one program written to take advantage of many CPU's (usually called Multi-threaded programs).
Hope that helps!
Describe the main types of primary and secondary storage?
Computer data storage, or memory, is the means through which the computer records and accesses digital data. The two types of storage are primary and secondary. Primary storage includes RAM and process registers, and secondary storage is the hard disk and flash memory.
What is the difference between short term memory and working memory?
In psychology, short-term memory is refered to as a passive store, that can temporarily hold a certain amount of information. Working memory however entails a broader concept. Working memory can not only store information but also manipulate information or inhibit irrelevant information. I am pretty sure that a lot of researchers do not agree with me, but you could say that short-term memory is a part of working memory.
Primary storage, also known as main storage or memory, is the main area in a computer in which data is stored for quick access by the computer's processor. On today's smaller computers, especially personal computers and workstations, the term random access memory (RAM) - or just memory - is used instead of primary or main storage, and the hard disk, diskette, CD, and DVD collectively describe secondary storage or auxiliary storage.
The terms main storage and auxiliary storageoriginated in the days of the mainframecomputer to distinguish the more immediately accessible data storage from storage that required input/output operations. An earlier term for main storage was core in the days when the main data storage contained ferrite cores.
2) Primary storage is sometimes used to mean storage for data that is in active use in contrast to storage that is used for backup purposes. In this usage, primary storage is mainly the secondary storage referred to in meaning 1. (It should be noted that, although these two meanings conflict, the appropriate meaning is usually apparent from the context.)RELATED GLOSSARY TERMS: hard disk, magnetoresistive head technology, yottabyte, serverless backup, byte, partition, InfiniBand, failover, RAMAC (random access method of accounting and control), Fibre Channel
Distinguish between in primary and secondary memory?
Memory can be categorized in different ways by technology or properties: primary access by the CPU or secondary (indirect) access by the CPU. This distinction is primarily based on the speed of access to the memory. volatile or non-volatile is a distinction based on technology (magnetic vs. electrical, etc.). Volatile memory requires power to maintain its stored information. Read-only memory, or read-write is a distinction based on properties of the memory. Read only memory, or "ROM", is not modifiable.
Number of computers per household in US?
In 2012, statistics show that there were 3 computers per household in the United States. The average of internet-connected devices, including smartphones, smart TVs, gaming consoles, tablets, and PCs is now around 5.7 devices per household.
The US Survey Group is a government agency responsible for conducting surveys and gathering data on various aspects of the population, economy, and society in the United States. They play a crucial role in providing statistical information that informs decision-making at local, state, and federal levels.
How you can enhance the capability of a micro processor?
There are several ways. One of them is to use software such as tweak, all kinds of optimization software (for instance jv16) which are able to clean the registry and do defragmentation of it. Also you need to defragment all your hard drives periodically (once per month or more often depending on how often you modify/copy/delete data).
You can use also hardware tricks like overclocking. Also to make an upgrade might a good idea if your computer is rather old or lacking power. You might need to add some RAM, replace the system hard drive with a drive with better performance. You might consider upgrading the CPU (if the motherboard supports newer CPUs). Also the video card might cause some discomfort especially if you are working under Vista.

What is a 8051 Micro-controller?
An 8051 microcontroller is a popular 8-bit microcontroller that was first introduced by Intel in 1980. It is widely used in embedded systems due to its simple architecture, low cost, and ease of use. The 8051 microcontroller typically includes CPU, RAM, ROM, I/O ports, timers, and serial communication interfaces on a single chip.
First word processor for micro computer is?
WordStar is often considered the first widely used word processor for microcomputers. It was released in the late 1970s and became popular among users of early personal computers.
Is there any difference between micro-controller and PIC?
PIC® 's are microcontrollers. PIC® 's are a large range of microcontrollers manufactured by Microchip Technology Inc. The 8-bit range, also known as the PIC16 range is a popular microcontroller range for beginners and students. Especially the PIC16F84 and PIC16F877. There are many books available that help students with the basics of microcontrollers. I would recommend any beginner to start by using a book on PIC's like "PIC in Practice by D.W. SMITH" or many others like PIC Trix and so on. A complete book will guide you better through the learning stages than the bits and pieces on the internet. Internet will help you allot once you are more experienced.
The PIC16F84 does not support USART (Universal Synchronous Asynchronous Receiver Transmitter) therefore it cannot perform serial communications such as RS-232 (comport) communications unless very unconventional attempts are made to create it in firmware (software programmed into the chip) which I don't recommend.
If you are a beginner and want to use PIC but also feel you want to extend your experiments to communications with a computer, other PIC's or serial IC's. Then I would recommend starting with PIC16F877 they may be intimidating at first, but after you studied its datasheet and learned some basic assembler or ANSI C, you can get started. For beginners I actually recommend assembler since it teach you more about the operation of the microcontroller in its core. I would recommend looking at www.microchip.com for the MPLAB program and search the net for MPASM compiler and ICprog programmer software (you need an extra driver for parallel port if you program via parallel port in win XP perhaps Vista as well). Unless you want to spend a fortune on programmer hardware you can build your own. a Tait style programmer may work well with ICprog, there are many circuits on the internet for this type of programmer.
Other microcontrollers are also available in the same level. There are MSC51 standard Atmel 89C51 or 8051 family and then there is Atmel AVR, like the ATMEGA8. The nice part about the ATMEGA8 for instance is that if you feel comfortable with this device and probably started using C language to make life easier. You find it very easy to move up to ATMEGA128 which is a more advance microcontroller. For AVR's there are a very resourceful website called http://www.avrfreaks.net/ go have a look.
The best approach to microcontrollers is not to commit your self to quickly to a particular one or brand name, "play the field a bit". Once you are more experienced it's best to use your experience and choose a nice microcontroller that can do most of what you will need and try stick with it or a very few variations at least. It takes very long to study and learn a particular make or model very well and you really do not want to go through all that every time you do a new project.
But to make your first MCU (micro controller unit) project a PIC project is not a bad idea due to all the basic educational resources and help available.
PIC is the series of microcontroller having some advance features then other series of microcontrollers like 8051. one is the speed that is fast in comparison and we can also interface usb through it.
Highest priority interrupt in micro processor?
The highest priority interrupt in a microprocessor is usually the reset interrupt. When a reset occurs, the microprocessor is forced to stop its current operations and begin executing the reset routine. This is critical for initializing the processor and setting it to a known state before starting normal operations.
Left bound report how would the left margin be set?
In a left-bound report, the left margin is set to align the text content on the left side of the page. This margin is typically adjusted using the page layout settings in the document formatting software or through CSS properties if working on a web-based report. A common left margin measurement is around 1 inch or 2.54 centimeters to ensure a professional and organized layout.
What is the top margin of an unbound report?
The top margin of an unbound report is typically around 1 inch (2.54 cm) to allow for headers and binding space if needed. However, this margin size can vary depending on the specific requirements of the report or the preferences of the person creating it.
A good slogan for educational institute?
"If there is a key, there must be a door,and I intend to find it."
What are the advantages and disadvantages of plotter printer?
Advantages of a plotter printer include the ability to produce high-quality, large-format prints with precise detail. They are ideal for technical drawings, architectural designs, and engineering diagrams. However, plotter printers are typically more expensive than traditional printers and may take longer to print due to their intricate, detailed printing process.
If the NTLDR file is missing on every system restart, you can try booting from the Windows installation disk or a USB drive and use the repair options to fix the NTLDR file. Alternatively, you can try using a bootable recovery tool to repair the missing NTLDR file. If these options don't work, you may need to perform a clean installation of the operating system.
A dual power supply refers to a system that provides two separate power sources to a device or circuit. This setup offers redundancy and can help improve reliability in case one power source fails. It is commonly used in critical systems where uninterrupted power supply is necessary.
