How do you check how much ink your printer has?
Firstly, you must have installed the hp Solution Center as part of your initial use of the product. In programs, find hp and click on HP Solution Center. When it opens, there is a row of three large square icons. The center is labeled Help and Support. Click on that and you will find a Topic Heading called Tools/Utilities. Under that heading find Printer Toolbox and click on that. A box will open with four tabs at the top. Click on the one labeled Estimated Ink Levels and there you will find a graphic representation of approximate ink levels.
ANSWER:- In the HP Director software, click Settings , click Print Settings , and then click Printer Toolbox.
- In the Printer Toolbox, select the Estimate of Ink Leveltab. Figure 1: Estimate of Ink Level tab
- If ink levels are low, replace the cartridge to get the best print quality. If one of the colors has been fully consumed, you must replace the cartridge.
What are the uses and different types of monitors?
There are two main types of monitors - TN and IPS.
There are also different sizes and aspect ratios of monitors too.
TN displays - what most monitors are. These types of monitors usually have poorer colour rendition and poorer viewing angles that IPS monitors, but they can have much higher refresh rates (100 hz, 120hz, 144hz etc) and their input lag is usually very low (1ms response time). These are best used for gaming as you need fast response times and refresh rates. They are usually cheaper that IPS displays.
IPS displays - more suited to those that are wanting to watch films in high definition, edit photos/videos or just enjoy the colour rendition a bit more than would be yielded with a TN display. IPS monitors tend to have normal refresh rates (60hz) and have usually higher input lag (5ms +) but their colours are MUCH better than TN monitors are are really fantastic for that. They also have much larger viewing angles ( up to 179 degrees). These are usually more expensive.
There are diferent sizes of monitors too, the two main options being 24" and 27". The sizing depends on what you want it for, but performance wise they are largely similar. 24" monitors are the most popular
One more point is the aspect ratio and resolution of the monitor. Most 24" monitors have an aspect ratio of 16:9, and a resolution of 1920x1080 pixels. These can vary (such as 16:10 aspect ratio monitors and 21:9) but it is personal preference. You can get 4K displays too, though these are very expensive currently.
Why have different block sizes for different partitions?
Sometimes using different block size can improve performance especially for RAID technology. If you are not using RAID, you will not see noticeable improvement if you change the block size.
List five simple things to consider when attempting to solve a PC problem?
1. If you smell any burnt parts or odors, don't try to turn the system on. Identify the component that is fried and replace it.
2. Is the power cord plugged in? If it is plugged into a power strip or surge suppressor, is the device turned on and also plugged in?
3. Is the power outlet controlled by a wall switch? If so, is the switch turned on?
4. Are any cable connections loose?
5. Is the circuit breaker blown? Is the house circuit overloaded?
6. Are all switches on the system turned on? Computer? Monitor? Uninterruptible power supply?
7. When you first plug up power to a system and hear a whine coming from the power supply, the power supply might be inadequate for the system or there might be a short. Don't press the power button to start up the system. Unplug the power cord so that the power supply will not be damaged. The next step is to open the case and search for a short. If you don't find a short, consider upgrading the power supply.
Name 4 memory units in which memory of a storage device is measured?
As far as my knowledge goes, it is like this
1. The smallest memory measuring unit is BIT
2. 8 BITS = 1 BYTE
3. 1024 BYTES = 1 MEGA BYTE (MB)
4. 1024 MEGA BYTES = 1 GIGA BYTE (GB)
5. 1024 GIGA BYTES = 1 TERA BYTE (TB)
and so on...
these units are generally used in computers and peripherals!
you!
What does it mean to have a clean desktop?
my start button is not working every thing is blank while moving cursor
I have run an Intel Pentium 4 to 102*C/215.6*F , though it is not good for it. the maximum you SHOULD run it to, tops, is 90*C/194*F
Not without specific authorization from the vendor. If the software came with the computer as part of the equipment. (This does not include PC-COE software)
How do you get horizontal lines out of the pictures from your printer?
Most printers will have a clean option in the printer properties. Try cleaning it several times. Also try the deep clean option if it has one.
If this does not work you may be able to remove the print head and soak it in print head cleaner over night should be enough.
If this does not work and you can get a cheap printhead from a certain online auction site you could replace it.
Alternatively replace the printer as they are relatively cheap to buy.
Well, the RSOD is like the BSOD (same thing) but is impossible to treat. It says it is possible with Microsoft System Recovery but it has never worked. If you ever got the RSOD you probably got technical support to fix it.
The RSOD (Red Screen of Death) will be shown when there has been a boot loader error in Windows Vista. There are several possible causes for this and if you are uncomfortable trying to solve your own computer problems, you should bring it to a repair shop; some of the possible solutions can further damage your computer if done incorrectly.
Try to get one more monitor just to check. If another monitor works with your computer, you have most likely problems with your video card (if you are not lucky it can be motherboard, or motherboard + video card).
Would the world be a better place without the invention of computers?
This is all a matter of opinion. The answer seems to be both yes and no.
It would be a better place if people had more closeness to one another and if social interactions were not as superficial and cheap as they seem to be these days. It seems that social networking and cell phones have cheapened social interactions and caused people to take them for granted. Such technology even causes people to get into the habit of demanding interactions where they are not desired. But at the same time, computer technology has increased the spread of information and helps people who don't normally see a lot of each other to still have contact and connection.
Then there are matters related to laziness and dependence. People put too much faith in technology and have forgotten how to do basic things without it. For instance, drivers will follow their GPS off of cliffs or into lakes, and few people can still do math in their heads. If the computer says it, then it has to be correct, right?
Does Handheld computers often have a specialized keyboard?
Tablet computers use an OSK (On-Screen Keyboard), usually supplied by the operating system or a piece of software that is supplied with the computer.
netbooks, notebooks and desktop replacements have their own keyboard, and need an identical keyboard if you are looking for a replacement.
mobile phones have their own keyboards, much harder to replace.
How many megabites are in a gigabite?
When referring to data transfer speeds (bits), the decimal system is always used:
- 1000 bits = 1 kilobit
- 1000 kilobits = 1 megabit
- 1000 megabits = 1 gigabit
- 1000 bytes = 1 kilobyte
- 1000 kilobytes = 1 megabyte
- 1000 megabytes = 1 gigabyte
Two types of numerical systems used with computers are the decimal system and the binary system. The decimal system is the official definition, which counts the kilo as 1000, while the unofficial binary system counts the kilo as 1024.
As an aside, the binary system that uses 1024 bits instead also uses different terminology. The kilobit becomes the kibibit; the megabit becomes the mebibit; and the gigabit becomes the gibibit.
Getting back to our more familiar decimal designations, abbreviations can often cause confusion. For example, an Internet provider might advertise speeds of 1500 kbps, while a potential customer might assume the abbreviation refers to kilobytes. Typically, measurements in bytes are used with a capital letter, such as "kBps," or "KBps." If all of the abbreviated letters are small case, the reference should be to bits. However, kilobit, megabit and gigabit might also be abbreviated as kbit, Mbit and Gbit, without any ambiguity.
What should a wrist strap be connected to when working on a computer?
To the computer metal case, or you can buy a wireless anti-static wrist band.
How often must the OWGM EC appointment letter be updated?
Appointment letter must be updated annually.
What is the profile of a computer criminal?
The typical profile given for a hacker is a young male, typically a loner, somewhat deviant, and who has poor social skills. But that is only a start and does not tell the whole story. Some are the self-styled mavericks, some are white collar professionals, and some are con men and scammers. So their motives vary.
According to taxonomists such as Marcus Rogers, there are at least 8 types of computer criminals. They are:
1. Novices - They rely on rootkits, they have little actual computer knowledge, they may be looking for media exposure, and they may cause extensive damage because they don't know what they are doing.
2. Cyber-punks - They typically understand the systems they are hacking and can write code. They are likely to be involved in fraud, and they typically want bragging rights.
3. Company insiders, type A - These are company insiders. They may be disgruntled employees of IT jobs who use their privileges to help them in their criminal endeavors.
4. Company insiders, type B - They are petty thieves who work in an IT capacity and are computer literate. They may be opportunistic and motivated by greed, and they may have a drug habit or gambling debts.
5. Coders - They mentor the newbies, write tools that others use, and are motivated by power and prestige. They tend to have hidden agendas and use Trojan horses.
6. Old guard hackers - They seem to have no real criminal intent, but little respect for the property of others either. Their main motivation is intellectual.
7. Professional criminals - They are likely to specialize in corporate espionage, and usually are available for hire by others. They have access to sophisticated equipment. They are also highly motivated and skilled.
8. Cyber-terrorists - A good number of these are from Europe where they may have been a part of intelligence agencies. Their motivations are mainly political in nature though they may engage in criminal activities for income. They use hacking as a form of political activism.

What is the solution of error code 80072e3?
Without knowing which program or system generated the error it is impossible to say. The error code is just a number. Many programs and systems may produce the exact same error code but its actual meaning is specific to the program or system that generated it.
It depends on the type of activities you want to accomplish. For example, if you want to browse the net, check your email, play a few simple games than 1.6GHz is more than enough. However, if you are using a heavy duty imaging software, editing video or playing a high end game than it may or not be enough, but it also depends on other computer specifications such as the amount of RAM you have to the power of your GPU.
