Build a Computer

If you are the do-it-yourself type like me who wants to boast that he built (ahem... assembled) the computer, without having a clue as to connect which wires, where, then welcome to my humble virtual abode. In this post, I will show you how to assemble your computer, which will come in handy, even if you are replacing the basic parts. Please refer to the pictures specified:

Fitting the components in the cabinet:

1. This is the cabinet. And if you are the penny-pinching type, this is exactly the thing to look out for. Now, almost all cabinets are equipped to deal with different motherboards, unless we are talking about a stone-age monolith. (See the elongated holes? exactly the things that allow for different sizes of components)

2. This is the SMPS (Switch Mode Power Supply), more like a distributor, which is responsible for powering up all the other devices like the CDROM or DVDRAM drive, the motherboard, floppy drive etc and in some older ones, even the monitor.

3. This is the motherboard (literally the mother of all devices), which means, whatever your computer thinks, it does that here. Make sure that you have an ATX motherboard (ask your dealer) before trying out whatever I suggest.

4. This is your CDROM Drive (you can also have a DVDRAM drive). Before fitting it into your cabinet, check that the pins are

5. Finally, the HARD Disk - this is where your computer has his memory. Without this, your computer will have complete amnesia, except for a things like date and time settings, etc.

Connections:
1. This, is the ATX (Advanced Technology Exended) power connector. Connect it as shown.

2.This is the EIDE(Enhanced Integrated Drive Electronics) cable, used to connect the computer's motherboard to the hard-disk, the CDROM drive and the floppy disk drive.

Connect it to the motherboard as shown below:

Then, connect the same to the CDROM Drive and the Floppy disk drive (if you have one, that is).

3. Connect the power.

The above example is given for the most general configuration. DO NOT try to repeat the same procedure on any other type of machine than a personal PC. The above procedure is a very general one and as we go along I shall post more detailed articles of varying complexity which will deal with more intricate topics.

Cheap Computer Guide - Computer Memory and its functions

PART 1
Computer memory is the fastest, simplest and cheapest
upgrade for your computer

Computer memory is very important to your system's functions.
A computer system's memory is its workspace. Everything the computer does is processed somewhere in memory.
The two main types of memory are Random Access Memory (RAM) and Read Only Memory (ROM).
Random Access Memory (RAM):
This is the computer's working memory and it has two distinct characteristics. (1) RAM is volatile which means all information stored in the chip will be lost when the system is turned off and (2) RAM can be written to and read from.
Today's operating systems (such as Windows XP, Vista, Windows 7) and application software require large amounts of RAM (Temporary Memory).
There are different types of RAM :
Dynamic Random Access Memory (DRAM)
This is most commonly used for main memory. DRAM is also referred to as fast page-mode (FPM). Since this is one of the cheapest types of computer memory, it is used as main memory in most computer systems. DRAM must constantly be refreshed on a regular basis; hence, while it is being refreshed, it cannot be read or written to. This causes system slow-down, which can be compensated by two methods; namely, paging and interleaving.
Paging:?? Improves memory speed since the memory is accessed in chunks called pages; hence, the name Paging. Accessing computer memory in pages is almost like reading a book because as long as the book is open at a certain page, you can read from the top, the bottom or anywhere on the page.
If you want to read the next page, you simply have to wait until the page turns which takes longer than skipping around on the page to read different sections. This is how paged memory works. Because when a page of memory is accessed, data can be read from anywhere in that section of memory.
Changing to a different page requires more time; therefore, the computer has to add a wait state. This wait state is time wasted for the Computer's CPU (Central Processing Unit) which has to wait until it can access memory (RAM). Click here and here to view cheap computer memory.
If you have fast enough RAM, the CPU does not have to wait to access data; hence the system has a "zero wait state". But since DRAM needs to be constantly refreshed, wait states are sometimes required.
Interleaving:?? Interleaved memory is accessed faster than paged memory. With interleaved memory, odd bytes are one bank and even bytes are in another bank. While one bank is being accessed, the other can be refreshed, saving time.
By using interleaving, computer memory access can be almost doubled without using faster computer memory chips.
Extended Data Output (EDO)This is an enhanced version of DRAM. Synchronous DRAM (SDRAM)
This is a type of DRAM that runs in synchronization with the system bus. SDRAM can operate at higher clock rates than standard DRAM. If SDRAM is used for main system memory, wait states are reduced or eliminated because the signals are already synchronized with the motherboard clock. SDRAM is the most popular type of memory used in new computer systems. At present, SDRAM can operate at speeds in excess of 800 MHz.
Static RAM
This operates just like DRAM except for one important difference - It does not need to be refreshed; hence the word static which means fixed. Since this computer memory is fixed or static and doesn't need to be refreshed, it can be accessed much faster than DRAM. Click here to look at some RAM
Access times for SRAM can be below 2 nanoseconds (ns) while access times for DRAM are between 60ns and 70ns. Since SRAM is faster than DRAM, why isn't SRAM used for all the system memory? Unfortunately, SRAM is physically larger, cost more to produce and consumes more power than DRAM.
Read Only Memory (ROM)
This is non-volatile memory which contains data that isn't lost when the computer is turned off. ROM is programmed into the chip by the manufacturer which means information is written to ROM during the manufacturing process. This information doesn't change once its written - it's stored in the chip permanently. ROM is used on motherboards, modems, video cards, etc. to store data, programs and instructions that must be retained when the system is powered down.
One good example is the BIOS (Basic Input/Output System) which is used to boot your system.
On boot up, the computer loads data from read-only memory (ROM) and performs a power-on self-test (POST) to ensure that all the components are operating properly. During POST, the computer memory controller checks all the memory addresses with a quick read/write operation to make sure that the memory chips have no errors.
BIOS is loaded from ROM and provides information about boot sequence, storage devices, security, etc.
Following this, the operating system (OS) is loaded from the hard drive into the system memory (RAM) where critical sections of the OS are retained as long as the computer is powered on.
This feature allows the processor to have immediate access to the operating system which enhances the overall performance of the system.
If an application is opened, it is loaded into RAM and only essential sections of the program are initially loaded and then other sections are loaded as required. Doing this, conserves RAM usage.
While using an application, any files that are opened are loaded into RAM.
After completion, the file can be saved and the application closed. When this is completed, the file is written to the dedicated storage device (hard drive) and both are cleared from the computer memory (RAM).

How to choose your desired laptop

When you want to buy a laptop course there are many things that need to be primed for your consideration not to see his brand. Each laptop any brand of the same strong and obstinate that famous and often also have problems like broken from it all, but all decisions must be viewed from what your needs for its application.
Here are tips and suggestions:
1. Make sure to what work will be used Laptops and any applications that will be installed so that you can prepare its budget, why would I say this because he later you would be wise to specify the options that suit your budget and limit choice unless you have lots of funds may choose a higher specification.

2. Choose Laptop with longest warranty period, and see what is in the warranty in the first year, two and so on read all the rules written on the card guarantees and choose which of his many services have a place not that many places services mean many are broken but that they are ready to serve you and facilitate you to repair and consultation of all your problems remembering things that laptops are often loyal to accompany you wherever you go, on your job especially if you are frequently out of town or out of the country so that all problems do not interfere with your work. 3. processor and memory is important because it must be balanced with the operating system and any applications you want to install ...
because if its fast processors but his memory is very small, or vice versa does not support to the working system of the laptop itself so it should be balanced ...
Suppose you want a laptop-based Celeron, Intel Core Duo, Core2Duo or AMD if its Windows XP operating system, at least you wear with memory ranging from 512 Mb and not more than 1.5 GB because not only will add to the budget was not balanced .. . except if its operating system has been using windows vista you may use more memory 2 Gb and also depending on the application software will be installed.
So I hope you are not wrong in taking a decision to buy a laptop like what best suits your own needs and expectations.

Apple's Magic Mouse

Apple once again shocks the cyber world by introducing Magic mouse. It is the world's first Multi-Touch mouse. It began with iPhone. Then came iPod touch. Then MacBook Pro. Intuitive, smart, dynamic. Multi-Touch technology introduced a remarkably better way to interact with your portable devices — all using gestures. Now with Magic Mouse Apple succeeded in bringing gestures to the desktop with a mouse that’s unlike anything ever before.

It has a button less multitouch surface where the mouse itself is a button. You can scroll in any direction with one finger, swipe through web pages and photos with two, and click and double-click anywhere. Inside Magic Mouse is a chip that tells it exactly what you want to do. Which means Magic Mouse won’t confuse a scroll with a swipe. It even knows when you’re just resting your hand on it.

Magic Mouse uses powerful laser tracking that’s
far more sensitive and responsive on more surfaces than traditional optical tracking. That means it tracks with precision on nearly every surface — whether it’s a table at your favorite cafe or the desk in your home office — without the need for a mousepad.

Magic Mouse connects to your Mac via Bluetooth wireless technology, so there’s no wire or separate adapter to worry about. Pair Magic Mouse with your Mac and enjoy a reliable and secure connection up to 33 feet away. When you combine Magic Mouse with the Apple Wireless Keyboard, you create a workspace free of
annoying cables.



And because Magic Mouse is wireless, it can venture beyond the confines of your desk. A quick flick of the on/off switch helps conserve battery power while Magic Mouse is tucked in your bag. Even when it’s on, Magic Mouse manages power efficiently, by detecting periods of inactivity automatically.

When you use gestures, it’s as if you’re touching what’s on your screen. For instance, swiping through web pages in Safari gives you the feeling of flicking through pages in a magazine. And scrolling with Magic Mouse isn’t your everyday scrolling. It supports momentum scrolling (similar to iPhone and iPod touch), where the scrolling speed is dictated by how fast or slowly you perform the gesture.

System Requirements

• Mac computer with Bluetooth wireless technology
• Mac OS X v10.5.8 or later with Wireless Mouse Software Update 1.0* or Mac OS X v10.6.1 or later with Wireless Mouse Software Update 1.0
• Existing keyboard and mouse for setup
• Two AA batteries (included)
