Before you begin make sure you have all the tools you need and a clean space to work.
Make sure you have all required tools and materials. Unpack the materials once package
at a time and inspect them to make sure they are not broke or defective. More ...
CPU Cache Basics
After the processor accesses a location in memory, there's a high probability that
the next location in memory that it will access is in the same area of memory. So
to make the computer run faster, a a smaller, faster memory called a "cache" is
placed between main memory and the processor. More ...
Understanding PC Data Buses
Physically, a "data bus" is the connection between the CPU and other devices on the PCs
motherboard. A data connection can be "serial" or "parallel". The data bus used in
first-generation PCs used 8-bit architecture. PCI Express uses switched serial connections. More ...

some of the logic circuits used to create the Arithmetic Logic Unit (ALU) of a microprocessor. More ...
CPU Chip Packaging
Over the development time of the computer, several different designs of packaging for the CPU
chip die have been used. Each type of packaging has its advantages and disadvantages. This
article reviews some common packages that might still be in use. More ...
The Fetch, Decode, Execute Cycle
The Fetch, Decode, Execute cycle is paramount to the functioning of a microprocessor. In this article
I'll describe the Fetch, Decode, Execute cycle simplified to its bare-bones in a highly simplified fictitious microprocessor. More ...
How Does a Laptop Battery Work?
There is little difference in how a laptop battery works and how other device batteries work,
except that a laptop battery is more intelligent. An electronic circuit works with the laptop
hardware to manage the power that flows into the battery while recharging and the power that
flows out of each cell of the battery while discharging. More ...
The Chemistry of Laptop Batteries Explained
Laptop batteries come in all shapes and sizes also differ in their chemical composition. The
chemistry of a battery refers to the chemical make-up of the cells inside the outer casing.
This artilce explains the most common chemistries used in laptop batteries. More ...
Intel's Core i7 Processors
Core i7 is a family of Intel quad core processors, that is, they have four processors on
a single silicon chip. All four processor cores and all memory caches, including a 64K L1
cache, a 256K L2 cache, and a shared L3 cache are located on one chip. The memory is also
located on the same chip. More ...
AMD's Phenom Processor
Since 2005 AMD has used the Athlon name for their processors. This changed in 2007
when they released their new processor called Phenom. So we must ask the question;
what is the difference between the Athlon and the Phenom? More ...
Motherboard Form Factors
The "form factor" of a motherboard defines its dimensions. Make sure that the computer
case that you purchase can accommodate the motherboard. It is also wise to select a
motherboard with a commonly available form factor in case you need to replace it. Article
updated with more information. More ...
