Connector at the end of the Ethernet cable?
The one that looks like an over-sized phone plug is called "RJ-45"
What is basic computer maintenance?
This is where the user maintains the computer without it being on the systems scheduled
list of things to do.
EG. Checking all the components are in working order
A microphone has a voltage output and an acoustical input. Only the sound wave can move the diaphragm of the microphone and a voltage signal comes out. That goes to to an amplifier and to a loudspeaker.
What is the name of the hardware component that enables a computer to send and receive data?
This could be a modem or network card most commonly, but can also be a large number of other devices. It depends on the method of sending and receiving- A CD burner or floppy drive can send and receive data, just not in an entirely automated process.
Buses are the set of wires that carry special information to or from the CPU. There are three types of buses
they are:
1. Address buses: these buses carry address given by the CPU from one unit to another in the computer.
2. Data buses: These buses carry data from one unit to other, it is a bi-directional bus i.e the data can be carried in both directions.
3. Control signal: These buses carry control signal from ALU to memory and from memory to alu and then to the output unit.
Factors to consider when acquiring hardware or software for your computer?
it is very simple. First, make sure the speed of the computer is tolerable. Second, check how much memory it has. the more memory, the better. Third, check the price. Always compare, and try to find the unit rates of how much youre spending. Fourth, check the physical features, like shape, size, and weight. Fifth, always try to make sure a compuetr has WiFi for wireless internet.
If you test all these factors, and you like it all, the computer will be perfect for you!
answ2. Only buy a machine with features that suit your needs. Even so, it will be obsolete in 5 years. it is not a lifetime investment.
How many types of bios do you have?
You generally have 1 BIOS on your computer, typically an Award Pheonix BIOS or some sort of proprietary BIOS developed by either the computer manufacturer or the motherboard manufacturer. In some of the newer cases, being with the iMacs and a select few new motherboards, there isn't a BIOS at all, but rather a advanced replacement known as an EFI. The concept of the EFI is very controversial because it creates new, unneeded complexities to the startup process at the expense of simpler setup and loadup GUIs. Haters of the EFI system (such as myself), tend to state that your loadup system isn't supposed to be used for normal computing and doesn't need things like this. We also like to use the old adage, "If it isn't broke, don't fix it."
What is difference between a Graphic card and Video card?
A graphics card, video card, v card, video board, video display board, display adapter, video adapter, or graphics adapter is a computer component designed to convert the logical representation of visual information into a signal that can be used as input for a display medium. Displays are most often a monitor, but use of LCD TV, HDTVs, and projectors is growing increasingly common with the growth of the media center computer concept. The graphics card and display medium are able to communicate utilizing a variety of display standards. Graphics card are both integrated into motherboards, and sold as expansion cards........ wow this guy just copied this from a dictionary

How do you destroy a DVD or CD?
Put it in the microwave.... commonly used by people in the military to destroy electronic documents... It won't hurt your microwave either,
They are just made (mostly) of thin plastic, so you can break them fairly easily if that is what you want to do. If you are trying to avoid destroying them, I recommend that you keep them dry. Water can damage them. Don't store them in direct sunlight, either.
What are the different types of buses in computer?
Silly answer - They come in many varieties, both double decker and single. Some even have open roofs!
More serious - There are a number of type of PC buses.
Front side bus, QuickPath Interconnect (QPI), or HyperTransport bus (HT): This connects the CPU to the memory controller or northbridge chip. However, in the HT and QPI implementations, the memory controller is a part of the CPU, freeing up the bandwidth of the bus for other things.
LPC bus: Used to connect the system BIOS, super I/O controller (keyboard, mouse, serial, parallel, floppy), and even a trusted platform module (TPM) to the southbridge chip.
Memory bus: This connects the memory to the memory controller, northbridge chip, or CPU.
Peripheral buses: These connect the motherboard to peripheral cards. This includes ISA, EISA, VLB, PCI, AGP, PCIe, etc.
What things use series circuits?
Christmas tree lights.
LIGHTS for Christmas do not need to in series but conveniently in series saves power.
A regulator while usually is in series does not be in series to regulate. FINALLY everything eventually are connected in series. from 475kv transmission to the local home device.
Consideration of choosing network topology?
Considerations for selecting a topologySelecting an appropriate topology for your deployment environment depends upon several factors.
When you select a topology pattern, consider the following factors:
- Available hardware resources
- Application invocation patterns
- Types of business processes that you plan to implement (interruptible versus non-interruptible)
- How heavily you intend to use the Common Event Infrastructure (CEI)
- Individual scalability requirements
- Administrative effort involved
Why would your computer shuts down automatically?
There could be several causes that a computer can abrubply shut down. Cause 1:
Stuffed with lot of Videos/Softwares etc in C:/ especially could cause your RAM Memory to go low. As a result of which, the computer might slow down and gradually shut down. In such cases, try increasing the virtual memory ....but see that while increasing it shouldn't increase your max memory allotted. Cause 2:
It could also be because your computer can have bad sectors. So, see that once in a month, you run scan disk especially C:/ Drive. Cause 2:
Maybe one or more of your vital files that are supported for your smooth running of your major programs in your computer might be deleted. This deletion occurs when specific viruses could delete such files. So, see that the softwares or the programs you install is not from an unauthorized site. You can download softwares from their official sites itself. To my knowledge these are some of the reasons y a computer can shut down abruptly. Jeet

What causes a computer to freeze up and how can you fix it?
Software incompatibility is one cause. That includes having two virus programs on your computer.
Other computer freezes may have other causes such as overheating of the CPU because the CPU fan is failing, power supply problems, failing hard drives, and operating system problems.
In Windows, there is the Event Viewer. That is where you can find system errors. You can try copying the text in the errors and search them on the web for possible solutions. A few of the events listed may even tell you how to fix them.
It also depends on what you are using when you experience lockups. If it is in the browser, you may need to reinstall the browser, or you may need to reinstall JAVA or Flash. In rare cases, you may need to find a JAVA or Flash remover before reinstalling those components.
How do you delete everything on the harddrive?
You can't delete completely everything off, as you will need some of the installed software to run the OS. But you can delete the browser history, temporary files, and any added software (using the add/remove programs). You can find the process for your specific laptop by checking the control panel and troubleshooting guides.
How do you turn off PC faster?
You can always try Defragmenting your hard drive.
1) Open up start
2) Open up accessories
3) Go to your system tools
4) Click on Disk defragment.
After it is done your computer should run more smoothly.. You should do this every so often to keep it running smoothly!
Note: It should be noted that modern computers with fast hard drives and high amounts of RAM will not gain a significant speed advantage from defragmentation.
A computer with a solid-state hard drive should not be defragmented; it is pointless and will degrade the drive, lowering its life.
See related links. It depends on what the limiting factors of your PC speed are, and what you use it for. For most people who are not computer literate, running Advanced Systemcare will boost performance.
How do you open bios on a compaq?
Okay theres a key combination you have to press when you first turn the computer on. Compaq changes theres from system to system, but it may be one of these.
F10
alt-F10
F1
alt-F1
F2
alt-F2
and so on...
A neat little trick that works on a lot of compaqs is this. Open up your case (with the power off of course) and unplug the ribbon cable from the back of the floppy drive.
When the system boots, it will give an error message & kindly ask if youd like to enter BIOS (or setup menu)
When youre done, dont forget to shut down & plug the cable back in.
