PCI BUS DEFINITION BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Computer System Initially devised by Intel and subsequently supported by the PCI Special Interest Group (PCI-SIG), the Peripheral Component Interconnect bus has become established as arguably the most popular and ‘future proof bus standard available today. It a...



DECIBEL AND LOGARITHMIC SCALE BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Basic Electronics WHAT IS THE DECIBEL SCALE? The range of powers, voltages and currents encountered in radio engineering is too wide to be expressed on linear scale. Consequently, a logarithmic scale based on the decibel (dB, one tenth of a bel) is used. The deci...



TROUBLE SHOOTING THE MOTHER BOARD OF A COMPUTER BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Computer System Most motherboard problems are related to cabling and connections. Ensure all cables are connected firmly. Ribbon cables and power cables can often come loose. Ensure all ‘plugin’ items such as the CPU, RAM modules and adapters such as video c...



COAXIAL CABLE CAPACITANCE AND CUT OFF FREQUENCY BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Basic Electronics A coaxial transmission line possesses a certain capacitance per unit of length. This capacitance is defined by: C = 24ε log pF/(D/d) Metre where C is the capacitance D is the outside conductor diameter d is the inside conductor diameter ε is...



VOLTAGE STANDING WAVE RATIO BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Communications When an RF cable is mismatched, i.e. connected to a load of a different impedance to that of the cable, not all the power supplied to the cable is absorbed by the load. That which does not enter the load is reflected back down the cable. This ref...



TROUBLE SHOOTING THE PCI BUS BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Computer System Trouble with PCI devices can be caused by Software bugs. Software settings. Hardware faults. Device conflicts. The standard way to fix software bugs is to obtain the latest card driver from the manufacturer. This can usually be achieved via the man...



REPLACING AND UPGRADING THE CPU BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Computer System Replacing the CPU The processor chip (regardless of type) is invariably fitted in a socket or a slot and this makes removal and replacement quite straightforward provided that you take reasonable precautions. The following describes the stages in...



MICRO COMPUTER BASICS
on Sep 28, 2012The basic components of a microcomputer system are: 1. A central processing unit (CPU). 2. A memory, comprising both ‘read/write’ and ‘read-only’ devices (commonly called RAM and ROM respectively). 3. A mass storage device for programs andjo...



SCATTER IN COMMUNICATION (SPORADIC E) BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Communications There are a number of scatter modes of propagation. These modes can extend the radio horizon a considerable amount. Where the radio horizon might be a few tens of kilometres, underscatter modes permit very much longer propagation. For example, a...



MULTI PATH RADIO PROPAGATION BASIC INFORMATION AND TUTORIALS
on Sep 28, 2012 in Communications Radio Reflection, refraction and diffraction may provide signals in what would otherwise be areas of no signal, but they also produce interference. Reflected – or diffracted – signals may arrive at the receiver in any phase relationship with the di...
