Intel makes a full range of processors for mobile computing, desktop computer and server applications. Most of the processors have different capabilities. These differences come in the number of processing cores they have, the features that they have enabled, and the speeds at which they run. The system bus frequency is the speed at which the processor chip communicates with the rest of the computer.
A graphical processing unit improves your ThinkPad's performance by handling the number crunching for graphically intensive processes. This frees up your primary processor to work on other tasks to keep your system running smoothly. A certain amount of noise from the GPU fan is a normal part of its operation, but strange noises could mean the fan is broken or wearing out.
When a Web page loads slowly or fails to load at all, the speed of your Internet connection may not be to blame. Sometimes the computer upon which you've stored the Web page slows to a crawl because of high CPU demands from the Apache Web server application. Reduce Apache's CPU usage by examining and making changes to your server hardware or Apache's configuration files.
Releaed in 2007, the AT&T Samsung Blackjack 2 is a Windows Mobile-powered phone that runs on AT&T's 3G network. By tethering it to your Ubuntu 64-bit computer, you'll be able to browse the Internet through the Blackjack 2's connection. Tethering the AT&T Blackjack 2 to your Ubuntu computer merely requires configuring the connection settings correctly.
Windows XP is a popular operating system that runs well on older computers. Updates are available in Service Packs (SPs) that apply changes to security and other functions. When SP3 was released in 2008, computers built with AMD CPU chips crashed due to a conflict between SP3 and the AMD chip. Some AMD computers fall into a cycle of continuous restarts, or the blue screen of death (BSoD) appears.
Computer processors have increased in complexity and capacity since their invention, and computer programmers have had to design their development tools around these changes. As memory size increases, such as in the move from 32-bit to 64-bit processors, old compilers and source code must be updated to take advantage of a processor's full potential. Part of this results from the increased space available for precision variables or numbers, such as integers. The GNU Compiler Collection, or GCC, is no exception. Although programmers can tweak GCC to work between 32-bit and 64-bit systems, the processor ultimately dictates what data sizes work…
After installing a new CPU fan for your computer, smelling an unusual smell once the fan is installed can be a bit disconcerting. However, a smell does not necessarily mean something bad is happening with your CPU fan. There are two types of smells that can accompany a new fan, and these smells can help you determine what is happening.
Simatic C7 control systems by Siemens are used in automated factories and facilities that use programmable heavy-duty commercial machinery. The C7 systems include a programmable controller and an operator panel that can function in a variety of extreme conditions, such as in industrial environments where strong electromagnets are used, where working conditions may rise as high as 122 degrees Fahrenheit and where machines have a high level of shock or vibration when running.
The architects at Bell Laboratories and their original associates at General Electric and the Massachusetts Institute of Technology designed Unix as a powerful multitasking operating system. The Unix kernel -- the core or center around which the outer functionality of the OS is layered -- talks to the bare-bones hardware via device drivers and to software to control processes and allocate system resources. A process on Unix is any executable control-flow procedure loaded in memory, and it gets the CPU's attention only when the kernel allows it.
The Leonite and Leonite2 are computer motherboards manufactured by ASUS for use in HP and Compaq computers. Both motherboards are built around the Micro-ATX form factor, which is designed for use in desktop computers. The Leonite and Leonite2 feature the Intel 945G Northbridge and ICH7DH Southbridge chip sets. The motherboards differ only slightly, and primarily in terms of branding, processor upgrades, audio specs and expansion slots.
Since about 2000, PC makers have been steadily introducing more 64-bit computers. Sixty-four bit computing surpasses the 4 GB memory limit imposed on 32-bit machines, permitting more sophisticated software. Though you can buy a 64-bit Macintosh, Linux or Microsoft Windows computer, native 64-bit Web browsers have been slow coming to market. Software vendors have released few full 64-bit versions of popular browsers such as Internet Explorer and Firefox.
Apple enthusiasts and PC enthusiasts have argued for years over which computer type is "better" or "faster," subjective terms that vary based on the kind of computing performed by a machine. Respected computer-oriented magazines have published benchmark comparisons between different model iMacs and PCs. You can benchmark your own PC against the iMac series by downloading a benchmark program and comparing the results to published results for iMacs with varying configurations.
Processor speeds affect everyday computing, work and play on your laptop. While computer vendors and websites regale you with the latest technical jargon, their specs often lack context, making an informed decision a challenge. Modern laptops of any class, except for the cheapest budget models, can take a full range of processors from the i3 to the i7, so consider how you plan to use your laptop, before deciding how much processor speed you need.
The limitation of your graphics card is not a simply answered question, as there's no across-the-board answer; it depends on the type of graphics card you own and the specifications of your computer. However, there are certain limitations to the way that graphics cards can access the CPU. This depends entirely on the build of the graphics card, and whether is has a dedicated graphics processing unit installed.
The Gateway Solo 9300 Pro is a 14.1, 15.0 or 15.7-inch notebook computer with an Intel Celeron, Pentium II or Pentium III processor in the MMC-2 or iMM form factor. The fastest processor the Solo 9300 Pro supports is the 700MHz Pentium III. If you purchased your notebook with a lower-speed processor such as the 366MHz Celeron, upgrading the processor can result in a substantial speed boost.
If a significant portion of your computer's central processing unit or "CPU" is occupied, it may prevent your computer from performing operations in addition to the ones currently running on it. For example, you may be unable to connect and use an auxiliary audio device via one of the computer's USB serial ports.
The motherboard serves as an intersection point for the other hardware on the computer. It is the place all the pieces come together. This makes a sound motherboard critical to the computer's health. A bad board can cause the computer to act erratically. This might include pushing the CPU usage up to 100 percent, but that is not the most likely cause of this problem. You should do some troubleshooting before assuming the board is the culprit.
Computer processor manufacturers use a variety of measures to benchmark processor speed. Notably, clock cycle frequency serves as a way to discuss processor efficiency. However, processor-clocking speed is not the only benchmark. The amount of data a computer can process and how it processes that data are essential to determining processor speed. While multiple factors go into determining processor speed, clocking speed itself is one determining factor.
Microsoft provides developers with free tools they need to create 64-bit code. Visual Studio has all the tools for each language, and it contains the .NET Framework, which is an integral part of each Windows program and operating system version. Install this software on your computer in order to write the code for a 64-bit compatible application.
Booting your computer starts or restarts it. A cold boot starts it up when it's turned off. A warm boot restarts it when it's already running. In either case, your computer must perform a specific sequence of tasks to complete the boot process. Any misstep on the path results in an alert, warning or error message, depending on the point of failure. To correct boot-cycle problems, you must identify them. Write down any error messages you see and note any sequences of beeps or flashing indicator lights.
Many computer programs, video games and movies allow you to change your monitor's resolution, which affects the quality of the display. Adjusting the resolution also can have an impact on other parts of your machine, such as the central processing unit, or CPU, resulting in increased or decreased usage.
Whether it's a website, video or a word processor, every application that runs on a computer is allocated real-time memory space on the processor. When an application uses more than its allotted processor memory it is said to have overrun or overflown from its buffer allocation. In other words, when the program writes more information into the memory than it is allowed to, it is said to have caused buffer overrun. Such buffer overrun can also occur when executing the program that processes JPEG formats.
Computer shoppers are now faced with another choice. In addition to processor speed and single, dual or quad cores, processor chips now come in both 32- and 64-bit varieties. For many who use their computers for Web browsing and email, this choice may not matter, but for those who create content or play video games, 64 bits may offer significant benefits.
Hyper-Threading Technology is a feature of some Intel processors that allows each processor core to work on two instructions simultaneously. With a dual-core processor, Hyper-Threading Technology gives your operating system four virtual processors to work with, greatly increasing the speed of some tasks.
The speed at which a processor runs affects the amount of heat it generates, which in turn requires power to keep it cool. As a result, you may notice laptop fans running more quickly and loudly as you perform intensive tasks with the computer. In general, powerful laptops are noisier than less powerful ones, as they employ powerful fans. If you are confident in managing component temperatures, third-party utilities are available to control processor speed and fan speed manually.
Do-it-yourself computer assembly is a difficult and potentially expensive hobby full of pitfalls and hazards. When making major upgrades, especially replacing a part as integral as a CPU, certain side effects or even simple accidents can occur that you don't expect. If you boot up your PC to find that your sound has suddenly stopped working, there are a few possible culprits to consider.
Developments in central processing unit architecture have enabled CPU manufacturers to integrate multiple processors, called cores, into a single unit. Computers have been using 32-bit registers for over a decade, but modern CPU cores utilize 64-bit architecture in order to make use of higher RAM capacities. Determining whether to go with a 32-bit or 64-bit multi-core CPU, however, depends on your needs.
Most computer CPUs are air-cooled. A typical CPU cooling unit has a metal heatsink that clamps to the surface of the CPU, increasing its surface area and drawing heat away. A fan then forces the heat away from the heatsink and out of the computer. Companies design a variety of CPU cooling fans marketed to users who demand top-notch cooling performance for quiet operation. The best CPU fan for your needs depends on which of these features you prioritize.
Central processing units require a heatsink and fan to keep cool. Some modern motherboards can adjust the speed of the fan using Smart Fan Control, which increases or decreases the rate of fan revolution based on temperature of the CPU. If the option fails to control the behavior of the fan, however, the problem might be related to the device or to the motherboard itself.
The heatsink has been a basic computer component for over a decade; central processing units have required these cooling attachments since the release of the first high-speed Intel Pentium processors in the 1990s. Most modern heatsinks are active heatsinks, meaning they include a fan attached to the heatsink itself. If your computer's motherboard fails to recognize a replacement fan and heatsink, the processor won't be able to cool itself adequately.
The Gigabyte GA-EP45-UD3P supports a 1,600 megahertz front-side bus -- a component used to send data back and forth between the central processing unit and a part of the chipset called the Northbridge -- and can utilize high-speed quad-core processors. Because the motherboard is capable of using powerful components, it needs sufficient cooling to keep the computer from overheating. If the CPU fan stops working due to a lack of sufficient power, the computer will shut down after a short period of time.
Although computer hardware runs faster every year, software seems to compensate by becoming more bloated and resource hungry. The Ubuntu Linux operating system is popular with newcomers and mavens alike because of its visual polish, simple installation and excellent out-of-the box hardware compatibility. The new Unity shell makes Ubuntu a distinctive, easy-to-use operating system. Many features that make Ubuntu a great Linux distribution, however, also increase its need for computer processing power and memory.
Processor manufacturers such as Intel and AMD have begun offering so-called "dual-core" or "multi-core" processors. For some consumers, the difference between these new processors and single-core processor may be difficult to grasp. Multi-core processors are a way for processor manufacturers to continue improving the performance of processors in the face of physical limitations in processor complexity. Multi-core processors can go beyond the limits of single-core processors, but with the condition that the computer’s software must work slightly differently to fully utilize them.
A computer Central Processing Unit is designed for a motherboard with a specific Front Side Bus speed such as 133 MHz. The FSB speed is one of two factors that determine the CPU's clock speed. Although it is possible to adjust a motherboard's FSB speed -- thus changing the speed of the CPU -- doing so can have negative effects.
The chipset, integrated into your computer's motherboard, provides pathways of communication between connected hardware and determines what technologies the Compaq Presario V2000 supports. The operating system interfaces with the chipset using a software called a device driver; installing this software enables the OS to provide video, universal serial bus, integrated drive electronics and serial advanced technology attachment support. The OS stores pre-existing drivers to the System32 folder. If Windows is having difficulty interfacing with the above devices, reinstall the chipset driver found in System32. If Windows has failed to install the proprietary drivers for the V2000 chipset -- instead relying…

Most programs and their associated files work on both the 32-bit and 64-bit versions of the Windows operating system, but there are some exceptions. Check program compatibility with the downloadable Windows Upgrade Advisor tool before changing to another version of Windows or to check if a program on a 32-bit Windows computer will also work on a 64-bit Windows computer.
Your computer's central processing unit (CPU) is the brain of your system and controls the various operations and processes the machine performs. The CPU is a small chip attached to the motherboard and usually performs its job quietly. A high-pitched sound seemingly originating from the CPU may indicate a problem, or it could actually stem from a nearby component. Noting when and how long the sound appears could help narrow down the cause of the noise and offer direction for correcting it.
Video cards typically include a fan that blows hot air away from the unit. Though similar in design, this fan is entirely separate from the central processing unit fan, as both units require their own cooling systems. In many computer systems, simply blowing air away from the video card is not enough. To ensure proper heat dissipation, you must understand how manufacturers specify thermal limits and how your video card fan contributes to computer airflow.
A laptop will save any data open before the system hibernates and allow you to resume work once it awakens. In some cases, your computer may experience complete CPU usage when it wakes, indicating a problem or conflict within the system.
While Apple has long advertised that their customers are safe from viruses and malware, this is simply not true. The Mac operating system protects users from certain attack vectors, but viruses can still trick users into installing them or exploit vulnerabilities in major software to get onto a MacBook. PC Tools' iAntiVirus is a free malware scanner, but a robust scan of your MacBook requires substantial CPU resources.
When you replaced or upgraded your Central Processing Unit, CPU, Internet Explorer 7, IE7's files were most likely damaged during the process.
