Which tool can be used to block incoming network connection to your computer?

A firewall is the tool that blocks ports, programs, or any other network traffic from incoming or outgoing connections.

Which computers would be able to communicate directly?

When several computers are interconnected, but no computer occupies a privileged position, the network is usually referred to as a peer-to-peer network. In this type of network, every computer can communicate with all the other machines on the network, but in general each one stores its own files and runs its own applications.

Who is the world's second computer maker in the world?

This answer varies on a few things. Are we talking about computer manufacturers or software developers? Both play a big part of computers. Some of the worlds leading PC manufacturers are: HP, Asus, Toshiba, Dell, and Lenovo. As for software there are way to many to be named.

What percentage of the world's population own a computer?

Today about ten percent of the world's population-some 600 million people-have access to connected computing. Evidence suggests, however, that this number may grow dramatically. Mobile telephony promises to reach some two billion subscribers soon. As Moore's Law continues to drive down the cost of computing, new form factors appear that better fit the daily lives of more people, and new forms of wireless connectivity enable communities to "leapfrog" to high bandwidth connectivity, a large new population of computing users may be enabled

What are the 3 core aspects of the computer technology?

Hardware and software. Hardware is divided into input, output, storage, process that are classified through its function. Software is divided into operating system (OS) and Application System.

What are laptop computers used for?

Basically, a laptop is just a computer. One can do all the tasks that he does on a desktop. But portability is the key advantage of a laptop.

What is the difference between a computer and a human being?

Does a full computer hardrive weigh more than an empty one and if so what does the extra weight comprise of?

Everything that is ever "in" a hard drive is in it from the time it's first made. The only changes made when something is written is in placement of things that are already contained therein. Therefore, the actual weight cannot change. There has to be some kind of in the physical makeup of the hard drive for the weight to change, and this only happens while the computer is on (electric current passes through). When the computer is off, the hard drive is made up of exactly the same components no matter how much has been written to it. Those components don't change in weight.

Why data input validation is important?

Validation on user inputs is very important for the security purpose of the database. If a user enters a wrong value many times then a database can be corrupt. Here are some database issues:

  1. Input attack.
  2. Buffer overflow.
  3. Automated input.
  4. Code injection.
  5. Hidden field manipulation.
  6. Cross-site scripting.
  7. Countermeasures.

What was the original use of the computer?

The same as today: computing. Applications of computing have changed as price and size of computers have dropped, as more people with different computing needs and wants have been able to get computers.

Basic computing applications:

What kind of computer is best for creating anime and such?

It takes teams of artists to make anime shows and movies.

First of all you need to practice drawing,digital or traditional.First is the manga.You can draw tradtional using Japanese Markers and draw the story(like a comic)and then scan it.The plot needs to be logical and interesting for the readers.

Second,publishing.

Third,the anime.Anime needs to be similar to the manga because every anime follows a manga(it's obligatory).

Fourth,an anime can be drawn tradtional(very hard and very much time) or digital.You ca use Photoshop for effects,Paint Shop Pro7 or 8, or Animation Sho Pro 7 to animate.You need to scan the drawings.

To draw on computer first you need to draw a sketch or a base.Base or sketch can be drawn digital form or traditional,but in traditional form is much more easier and it's highly recommended.Then scan it and save it on computer.Trace the lines and then draw on them using the programs I recommended.No need to worry.

Then the last thing:and opening and an ending(you can create your own music or purchase the rightfull owner's song for your opening or ending),voice actors,producers,sponsors etc.

What are the hard drive components of your computer?

The hard drive is a device used to store data on the computer long-term. Unlike RAM, data written to the harddrive (or HDD) is non-volatile and will not typically disappear when turning the computer off.

Harddrives work by using a spinning magnetically reactive platter (or multiple platters), and read and write information using an incredibly tiny, extremely sensitive magnetic needle called a 'head'. This head does not typically come into physical contact with the platter, as doing so will often break the head, causing what is known as a 'crash'. This causes irreversible and permanent damage to the head.

The platters spin at high speeds to deliver data quicker, typically 4200 and 5400 RPM for laptops, and 5400, 7200, and 10,000 RPM in desktops. Servers can also have SCSI 15,000 RPM hard drives.

Hard drives store data most users commonly interact with- Your operating system (example: Windows), music, movies, games, applications and programs, documents, and more.

Hard drives can also be used as temporary RAM in the event of a RAM shortage, however at an incredibly reduced capability.

Most modern harddrives average 80 MB/s read and 60 MB/s write, though may vary from model to model and situation to situation. Modern RAM is much faster. Typical DDR2 and DDR3 memory operates at 8000 MB/s or faster. You can see why the HDD is not preferable as use for memory, and thus why a RAM upgrade is the quickest way to speed up a computer IF it is ram deficient. The use of a hard drive as temporary memory is called 'Swapping' 'Paging' or 'Virtual Memory', and is referred to as 'Swapfile', 'Pagefile' and 'Virtual Memory Allocation'.

Hard drives are a direct descendant of other magnetic storage media such as Floppy Disk Drives, Drum Drives, and Tape Drives. It provides superior storage capacity, better reliability, and speed to Drum Drives and Floppy Disk Drives. Tape Drives can hold higher capacity (as much as 14.5 TB per tape in top models), but since Tape Drives are sequential (must read front to back, like a VHS or Casette, and must be 'rewound') and harddrives are random access (goes directly to the data), tape drives have been replaced by HDDs for performance purposes.

Hard Drives used to be sensitive to magnetic interference, much like floppies and tape drives, but newer drives are shielded from most magnetic interference, unlike floppies and tape drives.

Where can one purchase a standing workstation desk?

One can purchase a standing workstation desk at most major retailers. To get the best price you should probably look into Amazon or Overstock as well. Staples, Office Depot and other major office supply stores should have plenty in stock if you want to physically see one before you purchase.

If you have a really slow and old computer what can you do with it?

U can recycle them once u get a new one. But before you do that make sure that they cannot be fixed or optimized further. If you don't know how get some applications that are designed to do it for your. I mean if your PC could be saved, why would you waste your money on a new one. Try one of the registry boosters and see whether you really need a new PC or just a quick fix for the old one.

Finally if that doesn't help recycling is a green move that helps the environment.
