Computer Hardware

Output Device is a type of hardware component that conveys information to one or more people.

Visual Display Unit (VDU) = Monitor

Printer.

Sound output, speakers.

The address bus is unidirectional becos address information is always given by microprocessor to i/o devices. The data bus is bidirectional bcos it takes the data from other devices & also give the data to other i/o devices

I would use a joy stick if i had to. But i think that it would be cool because it would be a lot easier.

star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.

PCI Express bus standard or the USB 2.0 standard

This will generally depends on the components of your computer and what it's tolerances are. Some cases will commonly get to 100+ degrees F inside and others are layered with fans and such to keep the temp down.

As a rule, don't let it go much over 100 degrees F. If it's that hot in the air, it's reaching bad temps on your motherboard and various components.

What general combinations of hardware and software offer very slow or fast transmission speeds?

The time it takes to send, receive, copy, move and save files (data) from one storage media to another varies depending on the devices and the communication method being used. For example hard drive to floppy disk very slow (saving files to a floppy disk can be 10 times slower than saving to a hard drive), hard disk to CD slow, hard disk to hard disk (direct link) very fast, hard disk to flash memory fast, network server to hard drive using a LAN can be very fast but is dependant upon network traffic how many users are accessing the network at the same time, Internet to hard drive using the WAN via modem by email or from a website speed here depends upon the type of connection you have dial up slow or broadband fast and whether you are uploading or downloading and the amount of traffic. Size of file being sent will also affect this.

the device is used for chicken

1_ Updating the inputs and outputs.

2_ Perform logic and arithmetic operations.

3_ Communication with the memory.

4_ Scanning application programs.

5_ Communicating with a programming terminal.

I believe that the cache memory stores certain copied information that you go to most often from the hard drive. So, the unit checks the cache memory first before it checks the whole hard drive. That way you can find the location of a certain file faster in the smaller (cache) memory versus finding it in the bigger hard drive where it takes longer to find that same file.

Not by default. You need to plug an external USB CD-ROM drive in if you want to play CDs.

Machine vision has been characterized by a lack of standards, which has resulted in the necessity for expensive customization of systems. Today's objective is to investigate the development of a vision system which utilizes or establishes standards.

All the instructions to start computer are stored in BIOS (Basic Input Output System ) at ROM. Whenever computer is started BIOS checks presence and status of RAM and input & output devices like keyboard, monitor, printer, disk drives etc. After checking these devices BIOS searches operating system in different drives. On finding operating system BIOS startups the operating system and hands over control of computer to operating system.

Power cable is a thick cable connecting your computer to an electrical wall outlet. It can also be a thin wire connecting your modem or other device to a rectangular [ usually ] power supply to your electrical power bar or wall outlet.

Data cables are much thinner, used mainly internally, and can be many wires attached together horizontally to form a wide ribbon of wires. However, a data cable can also be a much thicker cable connecting your modem, router, printer etc. to your computer.

with the help of input devices we get output.

Steps:

instruction given(data in)-->process(in processing data in cpu)--> output derived

the output can only be derived when input proccessor is supported by input devices or drivers.

PC technicians avoid repairing power supplies because the units usually contain specific components that would allow the computer to operate even if the components are still faulty. It becomes better to buy a new one to avoid further damage to the whole system.

You would need either a S-Video, or HDMI out on the computer or a RGB or DVI in on the TV. If you have neither of these you can purchase a graphics card with HDMI out relatively cheap. Once installed you simply connect the cable. Anything less that HDMI/DVI will be hard to read as the resolution will be very low.

Some troubleshooting tools for Windows are Microsoft Fix It Solution Center and Windows Error Lookup tool or WELT. Two others are WinAudit and Joeware Utilities. These tools are all free to use.

An online system is a system that is connected to the Internet. An offline system would be a system that is disconnected from the Internet.

It would depend on what KIND of CD you want to make. The blank CD itself is the least expensive part; purchased in bulk, they go for 15-20 cents apiece. Assuming you already have a CD/DVD burner and software in your computer (most machines manufactured in the last 10 years include these), you can create CDs of document, picture, music or software files for no additional cost.

If you're asking about producing a music CD as a recording of yourself or your band, the cost escalates. You can use a computer as a digital audio workstation (DAW).

If you just want to record yourself, all you may need is a USB microphone and the software. Condenser mics with USB outputs are available from most musical instrument vendors (Check out: American Musical Supply, Full Compass, Musicians' Friend, Sweetwater, zZounds, Music 123) For the software, Audacity is a decent first choice and it can be downloaded for free.

If you also need to have a second input for a guitar or keyboard, there are small USB/Firewire preamp-interface units with 2 inputs (such as the PreSonus Aspire) also available rather inexpensively from the above vendors.

You will also want a good pair of headphones and some speakers that are of better quality than those provided with most computer systems. The above vendors often sell packages that include the interface, a good microphone and the speakers.

If you need to record an entire band, you will need a somewhat more sophisticated system. Professional software (Cakewalk, Sonar, SoundForge, ProTools etc.) which includes mastering (post-recording) software to put the finishing touches on your recording. Pro software also allows for plug-ins to add any number of effects, loops and/or instruments (as you can afford them).

You will also a better interface (with at least 8 inputs) or, possibly, more than one.

Whichever route you need to go, plug in your microphones, connect the interface to a USB or Firewire port and spend some time learning how to use the software. There's lots of on-line help about how to get the most out of your recording rig. Once you have something listenable, You can then 'press' the CDs on your own computer one at a time. Or, you can purchase a CD duplicator (from one of the above vendors or most any computer vendor such as PC Connection or Tiger Direct). Make sure it has the Lightscribe feature so that it can print professional looking labels on the CDs at it duplicates them.

Be aware, however, that there's a steep learning curve to all of this and, if you do your recording in a room that is less than acoustically ideal, the finished product may not be much to listen to. Demo quality at best.

If you want a professional recording, you will have to book space in a studio, hire the engineer and maybe a producer (a great idea if you can afford it since an experienced, impartial producer can make the difference between marketable music and just plain noise). You will then end up with a master CD from which you can duplicate yourself as noted above. Or, there are any number of companies that will dupe your disks in lots of 250, 500, 1,000 or more, including jewel cases and liners, for reasonable cost. Cost per disk goes down the more you order.

You should also be aware that, if you are recording covers of other people's music, you will need to pay royalites. Some newer music cannot be covered without direct permission from the copyright holder (usually a recording company). Performance rights for most music, however, can be purchased on-line through the Harry Fox agency (www.harryfox.com/index.jsp) at 9.5 cents per song per disk with a minimum of 250 disks.

Then, of course, you have to actually SELL the disks, but that another whole issue entirely.

It is better to run some malware scan like malwarebytes antimalware. However, cleaning Windows registry with Reginout registry optimizer is often recommended when computer freezes most of the times.

By default in windows XP when a user deletes files they go into the recycle bin where they reside until they are bumped out by other files the user deletes later. At which point they are actually deleted.

However when a file is deleted, the data still resides on the hard disk. Basically all the file system does is remove the file from its table of contents which leaves that dataspace open for use in the future whenever new files are written. The actual data will remain until that same space is allocated to another file & thus over-written. This is done for the sake of performance, as otherwise when you deleted a large file, it would take just as long to delete it as it did to write it. As it is, file deletion is near instantaneous.

There are utilities availble which can go through and recover and/or remove this hidden data. Recovering files in this manner is very hit or miss, many times the files will be corrupted or incomplete as most OS's are near constantly reading and writing to the hard drive, it is very likely -some- of the data will have been over-written.
