There are different types of computer hardware, and of course, it would have been undoubtedly simple to deal with one hardware at a time and find out the problems associated with it. However, we know that when anything in our machine goes wrong, we are not completely aware of what exactly has happened, or rather, which part is causing the problem. So, I have decided that I will present to you the article in such a way that, we take up the problem first and then go for the troubleshooting, rather than taking a look at the hardware and the problem that it can cause.
Problem #1: Computer Does Not Start at All
If your computer does not get powered up at all, then the problem is very obvious. It has something to do with its power supply system.
This is one of the procedures that can either be very simple or can go way beyond your capability to solve. The solution may be as simple as replacing the power cable with a new one or as complicated as dealing with the SMPS of the machine. The SMPS is the Switched Mode Power
Thanks to the internet, every item you could even want or need can now often be found online, in some cases being shipped from the other side of the globe to reach you. This is certainly true for computer components, which can be very beneficial as finding exactly what you need locally is not always possible.
Due to the need for high performing computer components for the building of new computer systems or their replacement of broken parts, there are many different types of online retailer supplying these items. They may be a specialist in one particular type of technical equipment, or they may instead be a general supplier that offers a wider range of related items.
Whichever retailer you settle on, it is important to verify a few things in order to ensure that you will be getting a product that meets your needs and expectations. Firstly, make sure that the online shop that you are buying from is reputable, as many computer parts can cost a great deal of money which could end up wasted.
To ensure reputability, it is advised to go with companies that
The central processing unit (CPU) of your computer can generate large amounts of heat, which if not dissipated properly, can damage the internal components, rendering your computer useless. For the smooth functioning of your computer, you must ensure that you have a proper cooling system in place, that can effectively dissipate the heat generated and keep your system cool.
The cooling system for your processor consists of a heat sink and a fan. The fan is attached to the heat sink, which is a block with numerous fins. The heat generated by the CPU is dissipated by the fins of the heat sink, and the airflow created by the movement of the blades of the fan helps to speed up the process.
It helps to know that the heat sink and fan that come with a new CPU are mostly of average quality, and only do a fair job in cooling your system. If you want a computer that works silently, or if your computer has been overheating of late, then it’s highly recommended that you invest in a high-quality fan and heat sink combination. So, how do you choose the right one for
The very basic difference probably even a child would tell between software and hardware is that, the latter can be touched and are actual physical components of a device.
However, the former (software) is simply bits and bytes, and is completely intangible. It can also be called the digital component of a device. Even though the basic difference between them is quite clear to most of us, there are some more aspects about each, one should consider when reading about differences between the two.
Let’s do a hardware vs. software analysis and see what they are.
Hardware and Software: What is the Difference Between them?
What is Hardware?
Hardware is a physical entity, or something which is tangible. However, hardware isn’t of any use without proper software, and vice versa. For instance, a microwave oven won’t recognize Android, as it is necessarily meant for a mobile phone. Likewise, an operating system or application software is of no use without suitable hardware. In brief, hardware of any device includes wires, circuit boards, chips, internal circuits, and every minor thing required for an electronic device to function.
Types of Hardware
Hardware has three major types; first ― storage and memory, second ― circuits and other apparatus, and
computer network is not made up of one machine or even one type of machine. It is a carefully designed system of different hardware components (networking devices) working in tandem with various rules and communication protocols. From the network scenario in a household, to a medium scale network in a school or mall to a large, border-crossing network of a corporation or service, a computer network is made up of various hardware parts, some standard and some rare and more complex. So, what are the different types of network hardware? Read on for a listing of such devices and a brief explanation of each.
Types of Network Hardware
Cables & Wires
Everything may be turning wireless nowadays but at least 2-3 wired connections have to exist somewhere in a computer network. Connecting a desktop to a router or the router to the modem, such connections are always wired and the common cable type used is CAT5 RJ-45. Wiring is typically thought of as being a Layer 1 (physical layer) device as raw data or signals are transferred from one end to the other.
Network interface cards is easily one of the most important components of a computer network. It is a hardware
The graphics card is also known as video card, graphic controller, graphics accelerator or display card. It is a PCB (printed circuit board) that has three major components. These components are video memory, video BIOS, and graphics processing unit.
The graphics card should be changed if it gives a poor performance or if you want more speed options for the computer games. In the first case, you need to verify that it is the reason for the poor performance and not the computer. To do this, use the scan disk or defragmentation options and look for bad sectors on the hard disk. You can also try using other ways to speedup your computer. If they do not work, you can conclude that the lowered performance is due to the faulty working of the card. Once it has been established that the graphics card is responsible for the low speed, you should upgrade it.
Some video cards are integrated in the motherboard and some are externally connected to the computer. Older versions of motherboards used a PCI (peripheral computer Interconnect) slot in order to plug-in the video card. Newer versions of computers use the accelerated graphics port (AGP). The latest version of computers
What is computer hardware? Hardware components like the monitor, keyboard, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) devices constitute a computer. The working of the monitor, keyboard, mouse, and I/O devices depends largely upon the CPU. Due to some minor causes, like loose connections or dust saturation, any of them can stop functioning.
Faults occurring in the CPU are most hazardous, as it has a very complicated structure. The CPU is an assembly of the motherboard, hard disk drive (HDD), random access memory (RAM), compact disc-read only memory (CD-ROM) drive, and the floppy drive. Unless you are well-acquainted with the CPU hardware, it is extremely difficult to pinpoint exactly where the fault has occurred. If any one of these components fail to perform, there are a few repair tips that can be followed. In order to view the circuitry inside the CPU, its casing has to be removed.
The entire functioning of the computer depends on this component. The processor chipset, that performs all the logical operations of the PC, is embedded in the motherboard. Ribbon cables, power supply, CPU, and RAM are the things to be checked first on the motherboard. Check if any of the ribbon cables
Basics for Beginners
It is essential to understand the fundamentals of hardware before moving on to any high level technical stuff. A typical computer system has 2 very basic components:
CPU (central processing unit)
Of course, in order to actually be able to use the system, you input devices, like the keyboard or mouse. Other devices, such as joysticks, game pads, game controllers, etc., also fall into the category of input devices. The monitor is nothing but an output device (or a display device) whose purpose is to display all the information to the user. Monitors can be categorized as:
CRT (cathode ray tube) monitors
flat screen monitors.
CRT monitors are the box-like monitors that have been around since the last 10-15 years. Flat screen monitors are relatively new, and they too, are of 2 types namely, plasma monitors and LCD monitors. The CPU is the actual functioning unit, i.e., it is the component that is responsible for the actual computing that takes place. The CPU consists of the following components:
Processor and cabinet fans
Floppy disk drive
These components have
If you know how to install sound card on your computer, you will be able to listen to all sorts of audio files. Music files, videos, movies, and audio-enhanced presentations are just some of the files that you can enjoy if you have it on your machine. Most computers that are available in the market today already have it on them, but sometimes you may need to install one.
Laptop computers do not provide you the option to open them up at will, and doing so nullifies the warranty. So, laptops will always have the best possible sound card installed in them when you buy them. On the other hand, desktop computers can be opened any time you wish. If you know how to install one, all you need to do is open up the machine and go ahead with it; it is as easy as it gets, and it only takes a few minutes.
First of all, you need to be clear about why you are installing this card. If you are facing problems, try some other solutions before you set out to replace it. But, if your computer does not have one at all, then you surely need to install
What happens when you turn on your PC? Lights come on the keyboard and monitor, the computer’s brand logo may appear on the screen, then the operating system loading message appears. This is all occurring on screen, but in the background, your computer is actually powering on and preparing its external and internal parts. Many assume the Operating System (OS) is the first program a computer loads and operates on but the actual start-up program is the BIOS.
BIOS stands for Basic Input/Output System, which is inbuilt in every PC during manufacturing and is loaded, run and executed when you press the power ON button of your PC. The BIOS is a sort of firmware interface for a computer. Different components, such as pen drives, graphics card, keyboard and mouse and disc drives attached to a computer, need to be initialized and identified to the computer. The BIOS does this in the form of a check-list (“turn USB ports on”, done) and this procedure is known as POST (power-on self-test). The operating system itself is a program, which needs to be loaded and executed. This too is performed by the BIOS, which locates the OS program on the computer’s hard disk
When it comes to electronics shopping, one cannot depend on instincts, price or trends. Today’s trend can end up being tomorrow’ bust. Plus callbacks and product returns can happen to any gadget. Pricing is often misleading. You can end up paying a lot more than necessary for something which could be replaced tomorrow. With electrical devices, one needs to be well-versed in specs. Specs or specifications can help you understand whether that device is right for you in the first place.
A camera with a low resolution is of no use to a nature photographer, who needs detailed images. Similarly a high-end camera with enhanced zoom, is not the device for your average soccer mom. One such ambiguous device is the webcam. Capturing video and transmitting it online for someone somewhere else to view is the webcameras basic function. But when buying a webcam, there are certain specs and points to keep in mind. Read on to learn how to pick the best webcam for your PC.
5 Tips for Buying a Webcam
1. Buy Based on Hardware
Based on what they are going to be connected to, webcams can be differently designed. Most laptops nowadays have a built-in webcam but older laptops
Apple is a name that is synonymous with great quality and brilliant design. Unfortunately, it is also a name synonymous with over-priced products. The Apple keyboard and mouse in particular have a very clean-cut and ergonomic design. You don’t need to lose heart though, you could get to see the Apple and eat it too! That is, of course, if you’re willing to make do with used or refurbished peripherals. These cost almost half as much as the brand new ones and are just as good.
Apple tends to release a new updated version of most of their computer peripherals every now and then, so you stand to get a very good bargain on a keyboard/mouse that is just a few months old. Here are a few pointers to keep in mind while looking around for a used Mac keyboard and mouse.
Check to see if there is any visible physical damage or loose parts on the keyboard/mouse. Remember though, minor scuffs or scratches will not affect the functionality of the device. You stand to get the best deal on keyboards/mice that have a few cosmetic issues but work great.
In case of a wired peripheral, make sure that the
Technology plays a huge role in modern living. The truth is that a huge number of people now rely on their mobile devices to get things done and this has brought in a great convenience for all. As long as you have a device that can handle multiple functions and you couple it with the right accessories, there is really nothing you cannot achieve without having to invest in too many other gadgets to make your life blissful.
If you have a MacBook, the USB-C to USB cable is one of the best accessories you can choose to have to make your operations easy. This is an adapter that connects the iOS device you have to USB accessories to the Mac using USB-C port. This simply means that when you have the cable you can connect USB hub, printer or an external hard drive to the MacBook easing sharing of information and transfer of the same. You simply need to plug the USB-C cable end to your MacBook USB-C port and connect flash drive, standard USB device or camera. The cable also makes it possible for you to sync and charge your iPod, iPad or iPhone adding a little more convenience
Check any electronics cabinet or area within the home and see tons of dust on the walls, shelves, and the electronic devices themselves. Electronics are definitely a magnet for dust, thankfully there are many ways to deter it and have a cleaner area.
An additional benefit to tackling methods for dust reduction around electronics is that they will last much longer. No one wants to invest hundreds of dollars in a television, computer or stereo equipment only to have it die in a few years. Dust is the enemy! Tackle it in the following ways.
There are a few popular methods for cleaning electronic devices, and they can work great in conjunction with other methods including the cabinet cooling fan as listed below. These methods include:
Feather duster – A feather duster is an easy way to remove built up dust from electronics without damaging them as it’s extremely gentle.
Damp Cloth – A cloth dampened with water is the perfect way to clean the screens and rest of the component. Just make sure the cloth is squeezed of water thoroughly and fingerprints and smudges will disappear too. Never use cleaning agents unless they specifically say they’re for use on electronics.
Dryer sheet –
Electronics often work overtime inside of 2015 homes and places of business. Computers, stereos, televisions and more are used all day every day by professionals and those seeking entertainment, and although they are built to last by most companies, they still need some regular maintenance.
One way to minimize the amount of maintenance is with the installation of a fan tray assembly. As most electronic components are stored within one area, these assemblies can control dust and debris in and around these items and keep them from overheating.
When a laptop is turned on, one can hear a light “whirring” noise. They often disregard it but that is the internal fan, working hard to keep the internal components of the device clean as possible. This is the same concept as installing a fan tray assembly in a space where electronics are housed or kept.
A fan tray assembly can come in all sizes and with fans in most cases. A standard assembly will have about three fans with space for more depending on the buyer’s needs. Optimal cabinet cooling is the main benefit for installing this assembly.
From the right supplier, the fan tray assembly will be prewired for easy installation. The best
Products designed using DFMA principles are extremely reliable than those that are developed through the traditional design approach. DFMA ensures a seamless, smooth and quick transition from design phase to production phase too
Advantages of using DFMA
One of the major advantages of using DFMA is the lower assembly cost and short assembly period. Also the time to market time is short enough. DFMA can help you lower assembly costs by using fewer parts and eliminating the ones which are not as important, thus decreasing the labour effort too. With standard assembly practices including vertical assembly and self-aligning parts, the approach lessens assembly time involved too.
Steps to take for Efficient Manufacture and Assembly
The final price of a product is proportional to number of parts and hence reduction in number of parts product quality and reliability typically increase. With fewer parts to worry about, there are reduced chances of misalignment.
One should ask whether the part can move relative to other part while performing its function, whether the part can be made of different material than the others and also whether it should be a separate component.
If the answer is “NO”, then the possibility of combining the part with others should be
The internet and the numerous quality office stationery suppliers that can now be found online means that it is easier than ever before for businesses to find what they need for the office environment, ranging from printer cartridges right through to reams of printer paper, pens, computer parts, and many other accessories and items.
However, buying online does not come without its risks. It is very easy to make mistakes when buying certain items that have to have certain specifications, and it is also hard to ascertain the quality of items before you buy. In addition to this, it is often difficult to know who is a reputable supplier before you actually place your order.
With this in mind, it is important to keep a few things in mind when you buy certain stationery products. Some of the products that you should be careful about buying online are printer cartridges. The reason for this is that printer cartridges can be particularly costly, and certain aspects such as quality and price can have a significant impact on your business.
Firstly, you will need to make sure that your cartridges are of the highest quality possible to meet your needs and stay within your budget.
Electronic cooling fans are an important component of any electronics cooling system – not only do they allow a fan to operate safely which ensures that expensive electronic equipment does not overheat, but they also stop contaminants from entering the electronics and safeguard against accidents involving the fan too.
As result, these essential pieces of equipment are widely available from online suppliers as well as offline stores, meaning that there is a great choice for anyone looking to make a one off purchase or buy in bulk.
Choosing a supplier can be difficult, as there are many considerations to make when picking out the right equipment and ensuring that you are getting good value for money on your purchase. With that said, here are four questions that you must ask your supplier of electronic cooling fans to ensure that you get the best service and best products possible.
The first thing that you must ask if what product they recommend for your particular electronic equipment. This is an important question to ask as not only will you be getting some valuable recommendations for products that will likely be suitable for your specific purposes, but it will also give you the chance to compare
Printers have become increasingly popular in both the home and the office. While using a printer, you should also know about the various operating information and printing equipment which comes along.
There are mainly two types of cartridges, namely, toner cartridge and ink cartridge. It is important to use the right type of cartridge to avoid harmful damages to the printer.
A toner cartridge is used in laser printers and contains a fine powder which can be magnetically charged. This fine toner powder is a mixture of carbon, plastic particles and black or other coloring agents which helps in making the actual image on the paper. Thousands of pages can be printed from a laser printer using a single toner cartridge. Printer companies usually recommend using their specific cartridges to ensure the highest rate of functionality.
It is important to buy a cartridge which is compatible with your laser printer. You can also buy a remanufactured toner cartridge at a lower price than the new one. There are mainly 4 types of toner cartridges available:
– OEM (Original Equipment Manufacturer) – It is the most expensive but the most commonly bought option. It refers to buying the cartridge made by the original company of
