The printer queue is a representation of the printers input and output?
What it is basically is a line of people waiting, but those people are documents or what ever waiting for there turn to be printed.
What are the similarities ROM and Hard-drives?
they are both storage devices. both have data that can be read and used during the operating of the computer.
What is a good name for a Computer Shop?
This is entirely up to opinion, and your demographic.
If you are seeking a more professional demographic for businesses and work systems, go with something that sounds distinguished. Real world existing example: Computer Repair Associates of Denver
If you are targetting gamers and end users, go with something exciting. Real world existing example: Tiger Direct, Big Daddy's Computers, Axle's Fear Computing
What is the storage capacity of cache memory?
Cache memory is a type of memory. It does not dictate a specific quantity. The actual amount varies and can best be determined by looking up the specifications for your particular CPU chip.
A vacuum tube is an instrument used to control the flow of electrons. The simplest form of this is called the triode and has three elements. An anode, a cathode, and a grid. The flow of electrons is always from anode to cathode the grid can influence the flow of the electrons. Like the light bulb the tube needs to be a vacuum or filled with gas to prevent the metals they are made of from catching on fire and melting.
The first person to discover that a grid could have an electric charge was Lee De Forest.

How does using a laser pointer to measure the data track spacing on cds and dvds?
First, make sure you have a laser pointer, and a protractor. You'll also need a black marker, calculator with tigonometry functions, an index card, several pieces of thin cardboard (cereal box or something similar), a sturdy box (preferably wooden), and a stack of books.
It's best to work near the edge of a table with good lighting. Anyway, place the CD, label side down, near the center of the workspace. Then put a piece of cardboard to the right of it, and another piece behind it. Both pieces should be about the same thickness as the CD itself. Place the box on top of all of this. If you want to avoid scratching it, put a piece of paper or tissue over the back half of the CD.

Short Answer: Yes
Long(er) answer: anything that receives signal from the computer to present something is an output device. This includes speakers, monitors, printers and other devices of that type.
How you can connect a pen drive card to tv circuit?
You Normally cannot unless you dsing a microprocessor unit similare to older palm computer with Usb Pen Drive Adapter and TV Tuner CArd ... Then transfer image of Pen Drive to TV Screen Via Tuner Card on Micro Palm Computer Adapter ?
Or Just Link you PC to your TV then Us RF Adapter To to as follows :
Pen Card { Possibly USB}
Connect to Computer

What is important to remember when cleaning crt monitors?
Switch them off and allow time for the CRT to discharge. Do not spray cleaner on the screen, spray it on the cloth. Only use a clean non-scratch cloth. Allow the screen to dry fully before switching back on.
What the key function of the home key?
when you are writing in Word (or similar program) the home key will take you to the beginning of the line. Control+home will take you to the beginning of the document.
No not really, it's the brain.
CPU is the Central processing Unit which receives input via input devices like keyboard, mouse , scanner, mic etc. It's main job is to process the input and send to the relevant o/p device.
It controls the flow and process of instructions, in time with a clock pulse.
It needs to handle both input and output of binary data.
What are the types and capacity of a pen drive?
The storage capacity of a pen depends on its rating. They come in 4 gigabyte up to 64 gigabyte sizes.
What happens when you boot up a computer?
The computer gets power from the power suply inside the computer. from there the computer's bios kicks on and starts the CMOS program that is programmed into the BIOS chip. the CMOS program then begins to quickly check all the hardware. first it checks what kind of processor is in the computer, then counts the memory. It then checks the drives such as cdrom and harddrives then floppy. then it checks all the pci, isa, etc. cards and any other devices in the computer and gives each an irq (interrupt request). then the Bios (on most computers) checks first to see if theres a floppy in the drive and if so is it bootable and if so boots from the floppy. If the floppy is not bootable it then looks on the first hard drive's MBR (Master Boot Record) to see if its bootable and if so then boots to that drive.. if that one is not then keeps checking until it either finds a bootable harddrive or tells the user no drives are bootable and usually asks to insert a bootable floppy or restart the computer.
What would be the first concern if another adapter card wants to be added into a PC?
As long as there is a free slot of the right type and an opening, if it is needed, the card can be inserted. However, adding a card usually will require more power so it should be checked to be sure the power supply is sufficient. If not, the ower supply will also need to be upgraded. Upgrading the power supply is not unusual if the new card going in the PC is a powerful graphics card. These can generate a lot more heat as well, so the ventialtion of the computer is important.
Transformer is a device that works only with AC (alternating current), and is frequently use to step up (increase) or step down (decrease) the voltage level. Therefore we can say that, in order to maintain or to bring the voltage level up to our requirement we use Transformer.
Though there are many classifications of Transformer, but more or less there purpose is almost the same, however only the function of instrument transformers (includes current transformer & potential/voltage transformer) is bit different. Voltage transformer is used with high voltage power systems and is use to bring the voltage level up to the rating where it can be measured easily by ordinary instruments (usually 120V). Similarly current transformer is used to bring the high rating of the current up to the value where it can be measured easily (usually 5A).
Rectifier is a device that is used to convert the Alternating current into Direct current or in short AC to DC converter is called rectifier. Rectifier is also classified as half wave, full wave, bridge, etc, but more or less there purpose is almost the same, except for the difference in their conduction pattern (half wave conduct for half cycle, full wave conduct in both directions for complete cycle). Conduction pattern of rectifier is determined by the number and working of diodes (the major component of rectifier).

Why do you need a backup for your home computer?
Because home computers, just like business computers have stuff on them we don't want to lose. Examples might be word documents like resumes, excel spreadsheets with your bills, and digital photos from your camera.
Where can I find a disassemble guide for acer 4720z aspire notebook?

It's not. A higher than needed power supply will not harm your computer in any way. It will simply cost slightly more and draw more power. As they are more expensive, higher-watt power supplies will often have better warranties. A higher wattage will also facilitate future expansion more easily, instead of you needing to purchase a larger one later anyway.
What is the speed of a 2.0 USB port?
The speed of a USB 2.0 port varies, depending on the hardware being used. However, the top speed the 2.0 port can reach is 480 Mbit/s.

Majour function of computer operating system?
Operating system is the system which bridge the gap between the computer user and hardware peripherals. It also associate all the hardwares properly. OS acts as the nervous system in the human body.
How do you set up a computer speaker system and sound card?
Plug the power plug into a wall socket and plug the jack into the green port on the back of your computer. The speakers probably have volume on them but you can change the volume from the computer if you want by pressing Start -> Control panel -> Sounds and Audio devices.
