Finally… An Easy To Understand Introduction To Computers

When you mention the word “technology,” most people think about computers. Virtually every facet of our lives has some computerized component. The appliances in our homes have microprocessors built into them, as do our televisions. Even our cars have a computer. However, the computer that

everyone thinks of first is typically the personal computer, or PC.

It is a general-purpose tool, built around a microprocessor.

A PC has many different parts such as memories, a hard

disk,

a modem, etc that work together. A PC is said to be “general

purpose” because you can do many different things with it

like: you can use it to type documents, send e-mail, browse

the Web and play games.

Let us look at the main components of a typical desktop

computer.

Central processing unit (CPU): The microprocessor “brain”

of

the computer system is referred to as the central

processing

unit. The CPU oversees everything that a computer does.

Memory: This fast storage area is for storing data and is

connected directly to the microprocessor. That’s why it is

fast. There are various types of memory in a computer

system:

Random-access memory (RAM): Used to temporarily store

information that the computer is currently working with.

Read-only memory (ROM): It refers to computer memory

chips,

containing permanent or semi-permanent data that does

not

change.

Basic Input/Output: Required to establish the basic

communication when the system is turned on. It is directly

connected to the motherboard.

Caching: The storing of frequently used data in extremely

fast RAM that connects directly to the CPU.

Virtual memory: Used to temporarily store data and swap it

in and out of the RAM.

Motherboard: This is the main board in the computer that

has

the processor, the RAM, the BIOS ROM, the timing and

control, the interrupt and direct memory access hardware

and

the keyboard interface on it which are connected to it

through the secondary connection.

Soundcard: this device attaches to the motherboard with a

socket called PCI, which allows the computer to play CD’s

or

music files, or MP3 CD’s. All soundcards have speakers

and

connectors. The quality of sound depends upon the quality

of the card.

Hard drive: This is the main storage device of a computer.

It stores information including the OS that allows you to

access it all. Most common OS for PCs is Microsoft

Windows.

And Apple computers use the Macintosh operating system.

Other drives: Most computers are also complete with floppy

disk and CD drives. These vary from system to system,

however all work in same way. They read information stored

on disks. These are necessary for maintaining and

updating

the computer’s software and operating system.

That’s the components that create the average computer.

Although there are many different systems, and configura-

tions, it is difficult to imagine our lives without them.

Homeschooling and the Introduction of Tablet Computers for Learning

With the new Apple iPod and all of the tablet computers coming out there are more and more e-books available. In the very near future all of the textbooks and educational material will be available for homeschooling parents to help in their curriculum teaching their kids. Indeed it’s already happening at a very rapid pace, and I’ve noted in the last three months the tremendous number of new educational e-books that are available to homeschooling parents.

In fact, if you go online and look at some of these homeschooling groups, it is amazing the amount of information they’ve accumulated to help teach their kids. If that’s the level they are teaching their kids, it far surpasses the public school, and yet I’ve also noted that there are some homeschooling parents that don’t want to move forward into the future using the high-tech devices. Now then, I realize that looking at a computer screen is probably not a smart thing to do for very young children, as their brains and minds are still forming, and you don’t wish to cause a discontinuity between the eyes and the brain.

But if someone is teaching a junior high or high school level and engaged in homeschooling, it would seem to me that these tablet computers are just the ticket. And they sure beat the textbooks because they come with interactive videos and can be linked to the Internet so each individual child can have a multimedia presentation of anything they are learning, on any subject known to mankind. Plus they can go online when their curiosity is piqued, and enjoy learning and discovery that way along with their homeschooling assignments.

Therefore, one could ask what is the problem with tablet computers and some homeschooling parents who are unsure of this new technology. My thinking is that not everyone is a first adopter, and it’s going to take some time especially for homeschooling parents who are perhaps working on their third child now and they have a certain way of doing things which has worked previously. However, these new tools can help accelerate learning, and increase the advantage of homeschooling, which quite frankly already has the advantage over public schools, and take learning to a whole new level.

If you are a homeschooling parent, perhaps you might kick around some of the ideas that I’ve presented here on a philosophical level and consider the migration to tablet computing for your home school curriculum. Indeed I will leave you with that, and I hope you will please consider all this and think on it.

Introduction to Gaming Computers

Do you know what a gaming computer is? It is a personal computer that has been created in order to process high amounts of data which are requested when playing multiplayer online games (role-playing) or online shooter games.

Since lots of computer games have become more and more complex, the graphics that are included here need more memory in order to be processed faster. All computers have a card with high-end graphics and with a fast central processing unit that is available commercially. When the processing unit and graphics card are fast, the time between the input of the gamer and the time of action that is put upon the weapon or the character is reduced. As you probably know, even a second can make the difference between losing or winning a game of this type.

Usually, gaming computers include a bigger RAM than what one might need for simple home apps. If a computer has a big RAM, then the CPU can access the information which is held in storage more frequently. This is a vital element for those who want to have a great gaming experience. This sort of computer is equipped with lots of USB ports, where the user can attach peripheral elements (steering wheels, aircraft yokes, game controllers, joysticks, etc.). The ports are placed on the front part of the computer in order to allow the peripheral elements to have faster access.

Clear audio and video are extremely important when it comes to gaming, and the computers built for this are normally excellent in terms of sound cards or graphics. Lately, technology has evolved impressively, and gaming graphics have started to look more alive than ever. Not to mention that the imaging system needs to have state-of-the art cards that can offer the graphics that one might need in this competitive world. It doesn’t matter if we are talking about stationary units or portable laptops. A computer that is utilized for gaming must have a better quality of the monitor screen and excellent stereo speakers.

The peripheral devices are highly specialized and they include input devices which are taken for granted most of the times. An example in this case is the keyboard. Lots of gamers would rather play their games in rooms that are low lighted or even without any light at all. This fact lead to the development of the back-lit gaming keyboard.

This is a keyboard that is projected especially for gaming and which has a certain type of keys that are meant to consolidate the commands that normally go into keystrokes. The keyboard emits a sort of blue light that is meant to highlight the keys when it’s dark. This was created for those who want to experience an effective gaming process and develop better reflexes.
