When managing and operating numerous electrical devices and systems, one will also have to deal with a plethora of cables, connectors, and other electrical components that keep them functioning. Due to the importance of cables in terms of power and signal transfer, they should be handled with care to promote an ease of maintenance, identification, and safety. Without proper cable management, cables can quickly become tangled and unplugged, and damage can occur depending on the severity of the issue. As such, one should familiarize themselves with proper cable management, and the various products that promote it.
 
One of the most simplistic ways to enhance cable management in a cabinet or installation is to utilize labeling. Labeling can be done through color coding or written tags, and such systems may be used to group related cable types, voltage levels, or more. For grouping, cable ties, lacing, rubber bands, or other such products may be used, or cables may be run through cable guides or can be affixed to walls. As some cables may be constrained in their ability to fit into a cabinet or installation, implementing labeling early can reduce the amount of stress you may later have if you need to increase the amount of cables in the assembly.
 
Many cables are sensitive to mechanical strain, that of which can cause them to break down and lose performance or functionality. To prevent such issues, cable strain relief components should be implemented for cables, wires, conduits, and hoses. Strain reliefs are often plastic or metal, and they clamp onto lines so that the amount of stress induced as a result of bends is minimized. Cable ties can also reduce mechanical stress as well, and they serve as a cost-effective solution for large bundles of cabling. When electrical lines are terminated at a socket or port, strain relief is generally a requirement so that the connector is not unplugged or ripped out by accident. Depending on the application, the required strain relief component may differ in its type and placement.
 
While a majority of cable management is executed in a cabinet or within a system, there are still many benefits to managing the cables that must go across open spaces. For instance, business offices and furniture are often designed with cable management in mind, some desks featuring holes for cables to be run through to reduce the amount of visible wiring. Additionally, dropped ceilings and raised floors also allow for cables to be efficiently routed as required in a space, all while enabling an ease of maintenance. With proper routing and organization, systems and devices can be connected as needed, all while reducing tripping hazards, disorganization, and more.
 
Once you have established the type of cables you will need to manage, the amount of bundles you have, and the space you require, it will then be time to begin procuring the various management parts you need. With cable harnesses, cable locks, cable entry systems, cable trays, cable glands, and cable grommets all serving as common options, the choice should depend on the amount of organization you desire and the types of cables present in an assembly.

If you have ever used a microphone to give a presentation, it was likely linked with a speaker or some other amplification device. Many assume that this setup is the only way in which a microphone can function. However, microphones can operate independently of any loudspeaker or such devices. In this blog, we will discuss the mechanism by which microphones can transmit data without an external playback system.
 
At the most basic level, a microphone is a device that is able to convert sound waves into electrical signals using a vocal diaphragm and transducer. Individual microphones will vary in design past the level of the diaphragm, with some containing additional transistors and transformers. In addition, depending on a particular component's need for power, a microphone can be labeled as either passive or active.
 
Similarly, loudspeakers and other output devices can function independently of a microphone. These devices convert electrical signals into sound waves which travel through the air and eventually enter a consumer's ear. With both descriptions laid out, one may notice that speakers have an inverse function to a microphone.
 
When these two devices are used together, as is usually the case, the microphone is linked to the output device by a cable or wireless transmitter. As the signal propagates through the line, it is amplified by the output device to increase its intensity. Between the input and output devices, several additional components can be added to further modulate the signal and are thus explained:

 
1. Microphone Preamp: This device is used to boost the low output from the microphone into a signal that is compatible with the external amplification equipment. Higher-end preamps perform additional functions such as lessening distortion and increasing gain.

2. Analog-To-Digital Converter: Since microphones naturally produce an analog output, analog-to-digital converters must be equipped to change the signal to digital.

3. Digital Mixing Console: These consoles are commonly employed in professional settings to combine, equalize, and modulate other characteristics of multiple sound channels before the signals move on. These robust tools can be used to modify real-time or recorded inputs.

4. Power Amplifiers: The last step before the microphone input reaches the loudspeaker is the power amplifier. These devices increase the magnitude of the input signal to be above the needed output threshold. Power amplifiers must convert input signals into a variety of different outputs. For example, the required signal power for devices such as headphones is in the milliwatts, whereas home theater systems may require up to several kilowatts of power to properly function.

Wireless microphones work using similar principles, but without the need for certain intermediate components. In these audio systems, the electrical signal from the microphone passes through the transmitter and is converted to a radio or infrared light wave. These waves travel through the air before being picked up by a receiver on the output device. Typically, wireless microphones and receivers are sold as a package because most are not interchangeable.
 
As you can see, both microphones and output devices can function independently of each other.

Whether for entertainment, education, or other purposes, projection screens are quite useful for displaying projected images for an audience. Projection screen equipment may be portable or permanent in installation, while others may even take advantage of inflatable screens for outdoor events. The screen that is used for projection will often differ depending on the application and environment, materials and designs being set to enhance how light is diffusely reflected.
 
For projection screens that are used for movie theaters, reflective screens are used, such materials either being aluminized or a white surface containing small glass beads. As projection screen accessories such as speakers and subwoofers are placed directly behind the assembly, evenly spaced holes are situated across the screen itself. Home theaters are fairly similar in geometry, often coming in the form of rigid wall-mounted screens or pull-down screens. Pull-down screens are quite beneficial for spaces where there is not enough space for a permanent installation, and such equipment is commonly produced with painted fabric.
 
In some instances, an electric screen may be used. These types are often situated on a wall, ceiling, or recessed within a ceiling. While typically being large in size, some may be available for home theater use. Often, these screens are raised and lowered with the use of electric motors that are controlled by a remote control or wall-mounted switch. Sometimes, the electric screen may even be automatic in deployment and retraction, operating when the projector itself is turned on or off.
 
Beyond such types, another common variation is the mobile screen. Generally, such equipment will come in the form of a pull-down screen placed on a free stand or a pull-up screen placed on a weighted base. Typically, such options are best when there is no wall or ceiling that the projector can feasibly be attached to. Alongside permanently installed pull-down screens, both types may either be tensioned or not tensioned. Non-tensioned screens often face the downside of constant movement if there is a current present, causing the image to be imperfect.
 
As visuals are simply projected onto the screen, rather than sourcing from the screen itself, as would be the case with a TV, image brightness and contrast will be dependent on ambient light conditions, the luminous power of the project, and the size of the projected image itself. Often, the larger a screen is, the less luminous the image will be when there is ambient light. To promote a clearer and higher quality image, the room should be kept as dark as possible. Furthermore, screen surfaces that direct light back at the source can also be beneficial. 
 
If a flat screen with high reflection is used, such equipment may suffer from hot spots where a brighter image is displayed in one area. High gain screens also suffer from a reduced viewing angle, meaning that one needs to be very selective on which screen they choose and where it will be placed. After narrowing down the various needs that you have for your particular projection applications, let the experts at ASAP IT Technology help you source all you require.

Are you debating the advantages of a laser printer? A speedy equivalent to older model printers, laser printers provide an economical solution to high-speed printing when precision, accuracy, and efficiency are key. Not to be confused with their relative, the inkjet printer, laser printers harness a specialized printing method dissimilar to most standard inking systems. In lieu of using a continuous ink jet (CIJ) or drop-on-demand (DOD) system found in most inkjet printers, laser printers employ a fuser unit for transferring toner onto paper or another medium of choice.
 
If purchasing a laser printer or fuser assembly parts is on your agenda, we want to ensure you have all the information you need to make an informed purchase. To better understand laser printers, we will dive into how they function, examining their parts and how they contribute to improved printing quality for offices and industrial applications.
 
First implemented for commercial use in 1976 by IBM and setting the precedent for future models, laser printers have modernized into multifunctional devices capable of printing, faxing, scanning, and photocopying — among other tasks. Manufactured in various sizes for home, office, and heavy-volume printing, laser printers can be chosen based on an individual's primary printing needs. For more specific applications, systems that only print in black and white (monochrome) or color are available for convenience. Outweighing standard printers with their capability to produce persistent high-quality, high-volume prints, laser printers are also advantageous for text documents and image printing. As such, they can print in a variety of color options for crisp, sharp printing of all text and images.
 
When initiating the printing process, a laser printer will always begin by repeatedly passing a laser over a negatively-charged, light-sensitive cylinder known as an organic photoconductor or “drum.” Constructed to improve photoconductivity, these drums are often made from N-vinylcarbazole or an organic monomer for the efficient deflection of electrons when exposed to light. Additionally requiring the use of an electrically charged powdered ink (toner) instead of a liquid toner, powdered toners are critical for their particular application within laser printers. As the laser moves across the drum, it will activate miniature electrostatically-charged dots which act to attract toner. Selectively depositing toner in specific locations with the aid of the negatively charged drum, a differentially-charged image along the internalized drum is then formed and ready to be applied to a printing material as the printing process continues.
 
Subsequently moving from the drum to the fuser component, the materials being printed on must then be heated to a maximum threshold of 801 °F to instantly fuse the toner to paper. This process involves passing paper through two rollers, a heat roller and a pressure roller, which act to evenly apply pressure and heat. Affixed in a fuser assembly, a heat roller consists of a hollow tube built with a suspended heat lamp while a pressure roller is simply a rubber-backed roller. Respectively, heat rollers and their accompanying radiant heat lamps serve to apply infrared energy along the entire expanse of a hollow cylinder, while pressure rollers act as a backing roller to firmly apply pressure. Once the fusing process has been completed, the finished product will display your image onto your printing medium of choice, and your paper(s) will be expelled for collection.
 
Promoting unparalleled clarity, laser printers are known for their efficiency when it comes to minimizing ink and energy waste, but at what cost? Though exceptional for long term cost savings, especially when comparing the cost of powdered toner to printer ink, laser printers have a higher upfront cost as compared to inkjet printers. Due to being newer in terms of technology, manufacturing costs for laser printers can easily be doubled. However, as laser printers continue to grow in popularity for their multiple benefits, the initial cost of a laser printer can be expected to drop in the near future, matching its competitors in terms of pricing and obtainability.

Random-access memory, or RAM, is a common type of memory that is found within countless computer and electronic systems. Capable of reading and writing data in any order, RAM can handle information with rapid speeds that are not seen in other similar devices. Over the years, multiple types of RAM have come about, including SRAM, DRAM, and EDO RAM. In this blog, we will discuss the primary variations of RAM computer memory, allowing you to better understand their capabilities and uses.
 
Static random-access memory (SRAM) is a variation of RAM that takes advantage of latching circuitry for the storage of data bits. As a form of volatile memory, SRAM can only retain its data for as long as there is power provided to it. Nevertheless, the amount of power required for SRAM operations is low when idle, and such devices are known for their high performance and reliability. As compared to other forms of RAM, SRAM does not have to be refreshed for its performance, though will typically be more expensive. When implemented within a computer or electronic system, SRAM will typically be used for the cache and internal registers of a CPU, rather than acting as a form of main memory.
 
Dynamic random-access memory (DRAM) is a form of semiconductor memory device, utilizing capacitors and transistors to form memory cells that can retain data bits. The capacitors of memory cells always exist in either a charged or discharged state, those of which create binary values of a bit. As the electric charge of a capacitor will slowly diminish over time, DRAM technology requires a periodic memory refresh to restore charges and retain data. Similar to SRAM, DRAM is a form of volatile memory. As such, it will only hold onto data for as long as there is power being provided to the device. The most common use for DRAM is serving as the main memory of computers and graphic cards, though such devices may also serve similar roles in video game consoles and other digital electronics.
 
Extended data out random-access memory (EDO RAM) is an early variation of DRAM chip, invented to improve the performance characteristics of fast page mode DRAM (FPM DRAM). Unlike such early DRAM variations, EDO RAM was capable of reducing the time between cycles as a new cycle could begin while maintaining an active data output buffer from the previous cycle. Creating an overlap in operations, EDO RAM memory could improve performance over existing RAM types for the benefit of various systems while making personal computers cheaper to construct. While EDO RAM served as an advantageous memory option for a period of time, the 1996 release of SDRAM superseded the capabilities of EDO RAM, rendering it fairly obsolete.
 
When deciding between various random-access memory devices, one should consider the specific needs of their application or system. Additionally, each type of RAM will typically feature a range of speeds and technological generations, thus one should also consider the transfer rates they desire and whether or not a particular component is compatible with their system.
