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 ...
1G, 2G, 3G, and 4G Cellular Wireless Standards
The meaning of the terms 3G and 4G have been made very confusing because some wireless carriers
have built new high-speed 4G networks from the ground up while other wireless carriers have chosen
to doctor-up their 3G service and market it as 4G. More ...
Power and Your PC
The power coming into a computer is the most critical component, and it may be one of
the most overlooked. It is just taken for granted that it will always be there and working properly. 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 ...
Advanced Micro Devices (AMD) Chipsets
Although most people think the microprocessor is the most important part on a computer's
motherboard, the "chipset" is equally important. With the introduction of the Athlon processor,
AMD gained the technilogical lead. AMD processors and chipsets have always held the advantage in value. More ...
Serial ATA Hard Drive
New computers will begin using the SATA (Serial ATA) interface to the hard disk. Some
new motherboards come with built-in SATA support. The SATA interface does not use
a ribbon cable. Instead, it uses a cable similar to a network cable with only seven wires. More ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type
and number of I/O ports, much of a computer's performance is determined by its chipset. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor
targeted for the workstation market to compete with Intel's Pentium 4. AMD's first
64-bit processor was the Opteron, released earlier in April that same year, targeted
for the server market to compete with Intel's Xeon processor. More ...
The PC (PCMCIA) Card
The PC card, technically called the PCMCIA Card is a form factor of a peripheral interface
designed for laptop computers. It was originally designed for computer memory expansion. More ...
