Tips to Building Your Own Server

Building a server yourself is an incredibly smart idea (assuming you have somewhat of an idea as to what you’re doing) as it will allow you to use used or refurbished parts (which are cheaper than new parts), and it will also allow you to customize the machine to your exact specifications. When attempting to build your own server, it is important to understand the crucial components that make up a decent server. These parts include the server’s processor, hard drives, video cards, memory, motherboard, PCI card, and power supply unit.

Processor

The processor, often referred to as the CPU, is the hardware within your machine that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. In other words, the processor is the brain of your processor. Processors have the incredibly important job of allowing your system the essential amount of power for its day-to-day functions.

Hard Drives

Hard disk drives (HDD) are storage devices used for storing and retrieving digital information. They consist of one or more rapidly rotating rigid disks (also known as platters), with magnetic heads arranged on a moving actuator arm that write data to the surfaces. HDDs retain information even when your system is powered down, making them an essential part of your server.

Video Cards:

A video card, often referred to as a graphics card, is an expansion card that generates a feed of output images to a display (generally your monitor). Video cards can be integrated either into your computer’s motherboard or its CPU.

Memory

RAM (Random Access Memory) is an extremely important aspect of your system. It is a form of computer data storage that your server uses for all of its currently active programs and processes. So, it almost goes without saying that the more processes you execute, the more memory will be taken up. If your server has an insufficient amount of RAM, its overall performance will suffer.

Motherboard

A motherboard is the heart of any computer configuration. Motherboards hold all of the crucial electronic components of your server system, including its central processing unit and its memory.

PCI Cards

PCI stands for Peripheral Component Interconnect. A PCI card, then, is a local computer bus that is used to attach hardware devices in a server system. Some of the typical PCI cards found in most computers today include network cards, sound cards, modems, extra ports, TV tuner cards, and disk controllers. While PCI video cards are available for older computers and servers, most video cards today are either AGP or PCI Express (PCI-e).

Power Supply Unit

Your server’s power supply unit (PSU) operates your server’s processor and other peripheral devices by changing alternating current from a wall socket to low-voltage direct current. Without a reliable PSU integrated into your server, you risk possible damage to your server as well as data loss when the PSU inevitably fails.

So there you have it, the major components found inside all servers. If you’re considering building your own, I highly suggest using refurbished or used server parts. These parts perform at factory standards and generally come with a warranty, just like new parts. However, used server parts will cost you a fraction of what new ones will. Who can say no to that?

Extending Toner Cartridge Life

When you figure out how to expand the life of your toner cartridge viably, this progression will help you to spare an incredible measure of cash. It is not recently your accounts that advantage when this happens in light of the fact that the planet appreciates as meager harm as conceivable moreover.

Also, refilling cartridges might be terrible for your printer if the maker never proposed reused ink or toners to be utilized on them.

Reused toner cartridges are not the best choice for a wide range of printers. Before you take the choice to utilize one, contact the maker and get affirmation from them whether this is perfect for your printer.

The first step in extending the life of your toner cartridge is to make sure it never goes dry.

If you are sure that you won’t print anything for quite some time, close the holes on the cartridges so as to ensure moisture remain in. This will only be effective if the cartridge is removed from the printer before having the holes sealed completely until you are ready to print yet again.

Always shake the remanufactured toner cartridges before installing them on the printer for use. Some toners have a habit of clumping together at certain areas of the cartridge and unless proper shaking is done, it will last for a much shorter period of time. This simple step gives you the opportunity to get extra hundred or more printed pages than if you had not done this. The sensor on the printer can be taped or masked off to make it less effective thus giving you extra sheets of printed pages from the cartridge.

Clogs on toner cartridges have a way of deceiving the printer that they have been exhausted. The clogs have a habit of appearing on the areas where ink or toner is injected into the cartridge and unless these are swabbed, you will be unable to print. Reset the printer counter because they are equipped with the ability to sense toner levels even if you are using laser printer cartridges. You can learn how to do this by reading the instruction manual issued to you when you bought the printer.

Cartridges that appear to run out of toner at an alarming rate should be checked by a qualified technician. This expert needs to focus on cleaning the dispensers on your printer which get seriously affected after a period of sustained or intense usage. This action will help prevent toner from clogging your cartridge thus interfering with its ability to print and serve you for a prolonged period of time. It is beneficial in that it helps printers to be kept in good condition thus being able to serve you much longer.

IP Digital camera vs Net Cam
