If your computer is running slow, but didnt used to, this is often caused by spyware. Download Spybot Search & Destroy or Lavasoft Adaware (both are free, linked below) and have them do their scan. Remove everything it finds & see if that doesnt improve things a bit.
Another possible solution is to open up the machine & blow out the dustbunnies. A clogged fan or heatsink can really heat things up, which can slow you down.
What is a solid state media with no moving parts on a computer?
A solid state disk (SSD) or a USB flash drive, either have no moving parts.
What happens when a PC is switched on and booted up from cold?
When power is first applied like this, the computer starts by passing power to the motherboard and, consequently, the BIOS (Basic Input/Output System - the thing that controls how devices communicate with each other). As power is passed to all of the other system hardware, the BIOS does a check on each of these parts to make sure it's physically able to send and receive communication to and from the other parts properly, among a few other basic sanity tests.
Once the BIOS has confirmed that everything is operating correctly, and there won't be any conflicts or faulty signals, it proceeds to check its boot method. In the BIOS settings, your computer is usually configured to first check if there's a bootable disk in the CD/DVD drive, such as a Windows installation disk, and try to boot the operating system on that. If there is not one, then the BIOS will usually next fall back to booting from the hard drive. The hard drive, among a lot of other components such as your CPU and RAM, fire up, and start loading data needed for your computer to boot the operating system (for most people, that's Windows.)
Once the operating system loads properly, that OS' kernel (the part that actually allows programs to communicate with the hardware, and consequently, the user, through the BIOS) loads hardware drivers - pieces of software that not only tell the computer that hardware is present and functional, but actually how to use it - what to do when the user presses a key on their keyboard, what to do when the mouse sends an electrical signal detailing movement to the left, etc. Once all of the hardware is accounted for and assigned drivers, and the kernel is fully loaded, the software atop the kernel loads. The interface that you can point-and-click in, the code that runs in the background whenever you plug in your media player, etc. Then you may log in and operate your computer.
Amazingly, for most people, this entire process takes less than two minutes - and there are many, many more steps involved that have not been detailed here. If you (carefully) alter the right settings, both in the BIOS and the OS, as well as hardware tweaks, you can shave this down even further. Some people are able to get a computer to a fully operational state in less than 10 seconds.
Is mugen the fighting game legal?
Taken from another question, also assuming you're talking about the game.
"yes it is completely free and legal and if you payed for it you were scammed"
What is a piece of information stored on your computer?
Defragmentation. This is when your hard drive restores each file to one contiguous location to reduce data access time and allows storage to be used more efficiently.
Hope this helps.
Is it better to keep wireless laptop plugged into a power source when in use?
No, if you have your power plugged into your laptop all the time. Your battery will decrease its performance until your battery will last only a couple of minutes until flat.
Is the ipod 80gb classic able to hold videos?
Yes as long as you have enough space on your ipod of course it can just download or open it in itunes and sync it. Also with the new ipod touch you can record videos with the camera and store them.
Hard Drive
Which number describes a computer's word size?
How often are computers chips supposed to double in power and speed?
our computer power doubles every 18 months
What is a gooey as it relates to computers?
I believe you mean gui (pronounced gooey) GUI - Graphical User Interface:
A program interface that takes advantage of the computer's graphics capabilities to make the program easier to use. Well-designed graphical user interfaces can free the user from learning complex command languages.
What is computer language and what are its uses?
A computer Language is the code we use to make computer understand what we want it to do. Its an Instruction set given to computer to perform some task. A computer does understands only one langue (native one) which is Binary 0 or 1 (or simply say ON or OFF) but since human are barely able to understand this language so they use interpreter that translate the code written in a language close to human being and converts it to machine code to it to understand and execute. Reverse Process is done to get the results back to humans. Such Languages are: Native: Binary (0,1) Low Level: Assembly C Intermediate: C++ High Level: C#, VB, ASP, JAVA, Python, PHP, Pearl, JASON, JavaScript, HTML, CSS, F#, Ruby ..... etc.
What are the precautions before purchase second hand computers?
When buying a used Mac or any computer, one should first plug it in to make sure it works.They should also remove the cover to make sure that there isn't anything lose, burnt or otherwise damaged.
That's a very broad set of questions, but I'll give a small explanation.
The Processor is considered the computers brain. All tasks have to run through it. When looking at a processor you have to look at the speed (in Ghz, the higher the better), the cache (in MB, the higher the better), and how many cores it has (most nowadays have at least 2, the more the better.) You can also find the core size in mm^2. The LOWER the core size, the better in general. Smaller cores tend to be cooler and use less electricity, allowing them to be clocked at higher speeds.
For most people the biggest speed increase comes from more RAM. RAM basically holds information until the processor can get to it. RAM can be in either Megabytes (MB's) or Gigabytes (GB). 1 Gigabyte is equal to 1024 Megabytes. The most common RAM sizes are 256 MB (Fairly rare nowadays), 512 MB, 1 GB, and 2 GB. Again, the higher the better, meaning you'd want as many GB's as possible. 1 GB is fairly standard in newer computers, and a lot of them will have 2 or even 4 depending on the price range. They can go higher than that, but most don't.
You can get into more details about RAM, but for beginners the most important thing to know is that more RAM is better.
The Hard Drive is what stores all the information on the computer. Most hard drives are Mechanical hard drives, which are the slowest kind available right now but are a ton cheaper than faster drives and can hold far more information. When checking the Hard Drive in terms of looking for speed, the higher the RPM's, the faster it will be. The Cache is also important, the higher the better (will be anywhere from `8 MB-64 MB probably)
If you're into gaming, the graphics card has the biggest effect on how fast games can run. Graphics cards are a lot trickier though. The core size on graphics cards matters more than on processors, because there are a lot of them out there and of a couple different sizes. Again, the smaller the core size (sometimes called the "die" size), the better.
For graphics cards there are also several speeds that need to be checked. The memory on it will have it's own speed, as well as the core clock, and the shader clock. For all of these, the higher the better.
And lastly, how much memory the graphics card has needs to be checked. In general anything over 512 MB should be fine, and most now have 1 GB. Anything over 1 GB is usually excessive and not needed, so don't feel like you have to spend a lot more money on a 2 GB version of the same card.
That's the basics, but keep in mind better looking specs don't necessarily always mean better performance, computer parts can be tricky to judge if you don't know what you're doing. Shop around, and try to read reviews and comments on any part you're thinking about getting. A simple google search of the component will bring you tons of both.

What qualifications are required for a job in computer sales?
To sell computers you need an basic understanding of all the computer parts in computers and you need a basic understanding on how to work an operating system. And you need to know what all the computer components are called in case you ever have a problem with an computer. To find out more about computers you should take a course at college this would help you find out more about computers and how they work if you do not want to do this you can search on the Internet on how computers work.
I hope this has helped.
List any two advantages of man over computer?
The primary advantage of computers to humans is the speed at which the machine processes information. Data processing in all it forms has raised technology to unheard of levels in the last 20 years.
What is the Brian of a computer?
the brain of a computer is the CPU (central processing unit) it controls all of the I/O and the computations with the addition of new video cards the graphics are taken from the CPU and put onto the GPU (graphical processing unit) so the CPU can breath easy as the GPU is doing all the heavy lifting when it comes to the graphics of games and high end movies such as blue ray and hddvd
Basically in the bottom right corner of your computer screen there is a button with an icon of a speaker , if you can't see it then go the arrow and click it , then click it once and click mute.
What are the different types of malicious codes in computers?
Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.
Examples include: Randex, CMJ, Meve, and MrKlunky.
Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.
Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.
The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.
Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.
Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.
The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.
Examples of boot viruses include: Polyboot.B, AntiEXE.
Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.
Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.
Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.
Once infected it becomes impossible to locate the original files.
Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.
This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.
Examples include: Elkern, Marburg, Satan Bug, and Tuareg.
File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.
Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).
Some examples include: Stator, Asimov.1539, and Terrax.1069
FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.
Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.
Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.
Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.
Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.
Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

Where is information that you view on the intenet stored on your computer?
Everything you view on your web browser, ie: internet explorer; firefox; safari etc. Are usually saved in your temporary internet files.
There are several programs out there to clean up these traces of personal data. Once in particular that I use is IOBit's Advanced System Care. Its free and spyware free. It runs periodically in the back ground to clean up privacy traces as well as speed up your computer.
This is not a spam message, I'm just some guy with the right answer for this one. Most things that you view on your computer are saved SOMEWHERE. Even when you delete a file it is moved to the recycle bin first, before it is completely removed. So clean up your Temporary Internet Files and your Recycle Bin. Those are just two of the places. There are just too many specific's to list. I'm sure most of your arent computer technicians like myself. So just go get the above mentioned program and save yourself a head ache.
