I do a lot of computer repair work and one of the first questions I get asked (after I fix the computer) is what can I do to improve the performance.

I-RAM, M-RAM: Good Bye to Hard Drives?

A couple of weeks ago, one of my lab associates made a comment about the advantages of the I-RAM and its speed with respect to the hard drive. What is an I-RAM?

Inkjet Printers

Printers came to the fore in response to the growing need of computer-users to reproduce permanent records of documents and keep a paper trail of necessary transactions. Commencing with simple, all-text printed documents, various outputs can be reproduced at present for home and office applications alike. An assortment of models and designs of printers has proliferated over the years, making printing simple correspondence to complex graphics and images easier and more stunning.

Router Firewalls

Router firewalls are electronic devices that function exactly as all hardware firewall systems do: they keep unknown people and software outside of your network. Specifically, router firewalls will only allow your network to communicate with certain computers/networks. Any other type of communication will automatically be blocked and logged (for archiving/investigational purposes). Router firewalls are meant to be a simple solution for connection sharing as well as basic network protection.

Printer Cartridges

There are so many different printer cartridges available. It is up to you to decide which one is most suitable for your printer. When you buy a printer cartridge, make sure you take into account the cost involved in replacing the cartridge.

USB Connectors

Today communication and technology have reached new heights. Various types of electrical devices can be connected to laptops, computers and mobile phones. A special port is installed in these devices from where a USB connector is attached. The other end of the port is connected to external devices such as printers and scanners.

USB Cables

USB cables are data cables used to connect a computer or laptop to an outside source of data such as digital cameras, video recorders, mobile phones and mp3 devices. These cables are compatible with the standard USB ports present in computers and laptops.

The Guide to Choose a Good Computer Keyboard

If you are spending lot of hours working with your computer, it may be worthwhile to get a comfortable keyboard. There are different types of computer keyboard around, which is the one most suitable for you? This guide teach you how to choose a computer keyboard.

What Are The Things You Should Look Out For When Buying A Hard Drive?

Storage space is not the only concern when choosing a hard drive. Most often than not, the speed of the hard drive is determined by other factor such as the drive interface and its rpm. Check out this guide to help you make a wise choice in choosing a good hard drive

CD Ink Jet Printers

CD inkjet printers use inkjet technology to provide fast, high-quality printing options to users. For a large number of printing applications on discs, CD inkjet printers are preferred by many people. The latest models of CD inkjet printers could cost you more than a thousand dollars, but their speed is much higher than the lower-cost models. On some of the auction sites, you may get one dirt cheap. But check the cost of the ink cartridges used by the printer, as well as its speed. For a non-commercial user, a secondhand CD inkjet printer could also do. But those who want to use it for commercial purposes should go for the latest models.

DVD RAM

DVD is a format to store optical data. It is used as a storage medium for movies with very high video and sound quality. The DVD RAM or the DVD Read-And-Write Memory is a disk specification. The DVD Forum came up with it in 1996 and since 1998, DVD RAM has been used in computers, camcorders and personal video recorders. The name is a shortening of the words Read-And-Write Memory and not Random Access Memory. Thus the acronym can be misleading. This disk has many small rectangles on its surface. It has concentric tracks and is accessed like a usual floppy disk or hard drive.

Laptop Battery

Laptop batteries are exclusively designed for every laptop model and make. Thus, the batteries required for a particular brand of laptop differ from batteries those that are used for other brands of laptops. The life of a battery depends upon the type of that battery. This means that a nickel metal hydride battery will have a shorter lifespan compared to a lithium ion battery.

Used Test Equipment

Test equipment refers to devices that are used to check the functioning and output quality of electrical and mechanical equipment. Precision test equipment is needed when dealing with advanced and complex technology to make sure that they can adapt to the harsh conditions they would be subjected to in the future. Companies looking at optimizing their fund utilization choose to either rent or buy used test equipment. According to researches conducted by firms and universities, the growth of the used test and measurement equipment market in North America has been phenomenal. Over the past five decades, local organizations, multinational conglomerates and governments have acquired used test and measurement devices and have benefited immensely.

Test Equipment

The development of technology, backed by new devices and inventions and the restructuring of previous ones has increased the efficiency of work of people all over the world. Electrics and electronics provide the very base for the growth of technology and are used in the testing of new devices and equipment. Electronics is a vast field that studies systems and technology that controls the flow of electrons and other types of charged carriers in various devices such as valves and semiconductors. Practical electrical engineering requires the testing of devices and gadgets to test the efficiency and durability of complex electrical machines and systems.
