Universal Serial Bus is an external bus that is used to connect a number of peripherals to computers, cell phones and other gadgets. A Micro-USB is very small in size when compared to the size of the Mini-USB and the old USB. In addition to the small size, a Micro-USB is more durable than a Mini-USB as it features a stainless-steel shell. The stainless-steel shell used in the Micro-USB allows over 10,000 insertion cycles. For lighter PDAs and cell phones, the small size of the Micro-USB makes it a better Read More

SPDIF, or the Sony/Philips Digital Interconnect Format) is used to carry or transport digital audio signals in consumer electronic equipment such as CD and DVD players, PC audio cards, and car audio systems over short distances. The digital signal can be carried over fiber optic (TOSLINK connectors) or coaxial cable (RCA connectors) and is also commonly used in home theater and stereo systems. SPDIF is based on the AES3 interconnect standard is capable of two 192 bit blocks (split into left and right channel data) which are divided into 12 Read More

The computer BIOS (Basic Input/Output System) is found on Windows computers. The BIOS is the first application launched during the computer’s boot process. The program is used to check for and initialize computer hardware during the start-up process prior to passing control of the computer to the operating system. Unlike the OS that is normally saved on the local hard drive, a computer’s BIOS is stored as updateable firmware on a ROM (Read Only Memory),  EEPROM (Electrically Erasable Programmable Memory), or flash memory chip on the motherboard. When was BIOS Read More

The Basic Input Output system (BIOS) is a type of software that provides an interface between the hardware components of a computer and its operating system. It is usually stored in a Read Only Memory (ROM) chip. As it is stored in a ROM chip, its contents can never be erased and can be accessed by the computer at all times. Nowadays computers have the BIOS stored on flash memory chips, which allows the BIOS to be updated at any time. The computer would not be able to function without Read More

Technology has ushered the use of video and audio interceptors alike to intercept just any type of wireless video-audio cameras in your immediate neighborhood, just in the turn of a dial. Using a Wireless Video Interceptor A wireless video interceptor is used by law enforcement agencies in order to determine if a specific location is being monitored through wireless intercepting devices present nearby. Such a device is Read More

Secure Digital (SD) memory cards are very simple to format. There are 3 main options to format the SD cards to the format needed. To successfully format an SD card, the write protection lock on the side of the card must be in the “unlock” position. SD mini and micro SD cards must be used with an adapter or specialized USB card reader when a computer is formatting them. The first option is to use a format utility. On most computer systems, there are generic formatting utilities available for nearly Read More

The MBR is the Master Boot Record. The MBR is a small program which runs whenever a computer boots up. The MBR is stored in the first sector of the boot disk. The boot disk may be a hard drive, a floppy drive, or even a CD or DVD drive. The Task of the MBR The normal job of the MBR program is to search the partition table for the active partition, copy the boot sector from the active partition into memory, and transfer control over to that program. If Read More

A memory card reader is a device that acts as a connection between a flash memory stick or SD memory card and the computer. In other words, it is a memory hub that makes it possible to connect multiple memory cards to the computer at one time. Once the memory card is attached to the reader and the computer, the user can easily transfer files to and from the reader. Another reason that a memory card reader is beneficial is because it offers different size memory slots. Since there are Read More

The CRT (Cathode Ray Tube), is the vital component in most computer monitors and televisions. It is responsible for the images that we see in monitors and television sets. How a CRT Works The main component of a CRT is the picture tube. The tube is wide at the front and narrows at the rear end. The shape at the rear end can be compared to a bottle neck. The rear end consists of a negative charged filament, which is known as cathode. The filament is enclosed in a vacuum Read More

With color printers, it has become much easier to print pictures that have a considerable amount of quality to them. On top of that, now that there is inexpensive picture paper available, the quality of picture that can be printed is even greater. So long as the printer is of a good enough quality that it can handle specific details, the pictures that come out of it will look intense. Printing Pictures The first step is to open the Windows Photo Gallery program. You can find this under all programs. Read More
