Computer Components for Idiots

There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it’s not a computer.

The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That’s your basic computer.

Mother WHAT?

The motherboard (“mobo” for short) is the foundation. Everything attaches to the mobo — the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body — it provides support for the internal components and also passes information between the computer parts.

CPU

If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU.

The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance.

Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although each passing month will see increasing performance. This measurement refer to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer.

CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span.

Computer Memory

RAM (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory.

The most common type of RAM these days is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM.

The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory.

Hard Drive

All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for.

It holds the computer’s operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data.

80 gigabyte hard drives are common, but 400 GB units are available. Furthermore, you can install more than 1 in a computer case for added security and convenience.

Peripherals

All you need to complete the basic computer system is a monitor, keyboard and mouse.

Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls.

So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate mobo for your computer needs is the first step and may require a quick call to your local geek.

Soon YOU will be considered the local geek!

The Myriad of Circuit Board Hardware Components and Applications

Circuit board hardware refers to a range of supports for the circuit board which include locks and supports of all kinds. There are releasable, threaded locking, edge holding, adhesive base and blind-hole locking supports.

Circuit board hardware supplements the various forms of supports with relevant support posts. There are all sorts of support posts in the market to cater to the wide range of industry and domestic applications. One can procure mini support posts, locking support posts or dual locking mini posts depending on the required application.

Components

Besides the supports, the board hardware line includes spacers. There are many kinds of spacers which are available for all types of industrial applications such as push-in spacers, reverse locking and wide base spacers.

Standoffs are another board hardware component. There are snap-in standoffs, standard threaded standoffs and male or female threaded standoffs.

All these components are necessary for the circuit to work well. This collection of crucial components and their accessories is vital for the board to function well to secure, fasten or lock the circuit board. The combination of circuit board components make up the important printed board that is used in many technology applications.

These hardware pieces can be of brass with nickel coating. Circuit supports are usually of nylon in natural colors.

Suppliers

There are many trustworthy circuit board hardware suppliers in the market today. These may be small family-run businesses in the neighborhood or large conglomerates with many branches serving the communities across the nation. Some have overseas affiliates and subsidiaries that would be able to ship any part of the required circuit board component in a day or two.

It is an easy task for these hardware suppliers to transport any required circuit board component for any application.

Applications

The circuit hardware is an important element in many modern applications which require manual installation instead of automated installation. There are many applications in the market that make use of PCB.

Circuit hardware is used in many of today’s electronic equipment. Computers, hand phones, automated machineries, smart phones, televisions, home theatre sets, cars and many other daily electronic appliances use circuit hardware to function. This piece of electronics allow society to enjoy a more affluent and comfortable life which raises the standard of living in any civilization.

Whether it is an industrial application or domestic one, there is bound to be more than one application found in the home or office that has a circuit board hardware component.

Computer Components and the Importance of the Case

For those who prefer to design and build their own computers from scratch, the internal features that comprise the system’s operating power are but one of the considerations that go into the design and planning process. The casing is another of the important computer components that cannot be overlooked. Not only does it cover your CPU, motherboard, and other essential elements – it also provides protection and aesthetics for what would otherwise be an open collection of sensitive parts.

There are a wide variety of cases available to house your computer components, most of which are based on the industry’s ATX standard for size and layout for housing motherboards. Since all of your computer components will be housed within the casing, it can easily be considered the backbone of your computer system. When choosing a case, there are some important considerations you need to make.

Those considerations include the number of expansion bays, and ease of access. Expansion bays are the slots in the front of the casing through which you can access various removable drives like a DVD or DC-Rom drive. If you plan on upgrading your system throughout its life, you will want to ensure that you have an excess of expansion bays to accommodate future drive additions. The ease with which you can access the internal components is an important factor, as it will determine how easily you can perform anticipated upgrades, as well as perform regular cleaning to remove dust and dirt.

How your casing is laid out will indicate how efficient your computer’s fans are at keeping the internal computer components cool – thus reducing or eliminating the cause of most computer freezes and crashes. In addition, casings with quality filters over the fan area can help to eliminate dust and other particles that can contribute to excessive heat.

As you can see, the casing for your computer is one of the most critical computer components you can buy. Taking the time to choose the right case can go a long way toward ensuring that your custom designed computer has a long and efficient life.
