Basic PC Anatomy
Change Raspberry Pi Default Configuration
If you are a US user of the Raspberry Pi, you will discover that when you type, the characters displayed do not match our keyboard.
When you type [shift][#] instead you get the British pound symbol. This is because Raspbian (and NOOBS) defaults to UK keyboard settings. More ...
Basic Computer Thermodynamics
Picture the CPU of a computer cooking away because the designer wants to push too
much power through a small piece of silicon. If we don't take away that heat as fast
as it's created, that CPU will fry! More ...
The Small Computer System Interface (SCSI)
SCSI is complicated to configure and troubleshoot with incompatibility between devices
being a common problem. To setup a SCSI system, you need to know which SCSI standard the
devices support. The host adapter must match the devices. More ...
Program Flow Charting
Depending upon the language used, program code my be difficult for humans to
read and understand. However, one type of programming that is very easy to
understand is flow charting. More ...
Network Interface Card (NIC)
A Network Interface Card (NIC) is an expansion card that allows a PC to connect to a
network. Though there are many different types of networks, PCs almost always use a
NIC that interfaces to a wireless network or an Ethernet network. More ...
Basic Decoder Circuitry
A microprocessors is a circuit that reads and execute program instructions called opcodes.
A decoder is a circuit that converts an opcode into signals tused to control the circuitry of
the microprocessor to enable it to perform the instruction. More ...
The original 4.77 Mhz 8088-based IBM PC released in 1981 was built with over 100 discrete
logic chips. To lower the cost of manufacturing, the logic was integrated into a couple of
chips that were used together as a set. They became referred to as a chipset. More ...
Mach Speed P4MSD-800 D2 Via Socket 775 MicroATX Motherboard and Intel Pentium D 940 3.20GHz Processor Bundle
Based on the VIA P4M800 chipset, the Mach Speed P4MSD-800 D2 motherboard supports up
to 2 DDR2 memory modules at 533MHz, up to 2GB. This high-end platform also supports
AGP 8X, SATA, 6-channel audio, USB 2.0, Fast Ethernet LAN and more. More ...
CompTIA A+ Training Kit - Safety Issues
When working on computers it's important to pay attention to safety considerations. CompTIA A+ Training
Kit teaches computer safety issues as required for CompTIA A+ certification. More ...
A microarchitecture describes the physical features, functions, and the technology level of the
processes used to manufacture the core of a microprocessor. This article describes the microarchitectures used by AMD. More ...
External Serial Advanced Technology Attachment (eSATA)
Initially all SATA (and PATA) interfaces were for internal hard disks. With the introduction
of eSATA, the SATA interface can be used with external storage media. This puts eSATA in
competition with Universal Serial Bus (USB) and Firewire. Especially since, like USB and
Firewire, eSATA allows hot swapping. 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 ...
