A digital camera is a portable camera that electronically captures an image by recording photons of light as they come in contact with a sensor inside the camera. While a traditional camera records an image through chemical reactions, a digital camera records an image by converting individual colors of light into corresponding numerical pixel values, ranging between 0 and 255. Digital cameras are used for capturing images, recording videos, and communicating. The Basics of a Digital Camera The manual camera requires a film to store the images that were shot. Read More

The first thing you can try to increase a WiFi signal is to move the laptop computer or mobile device closer to the source of the network that is being accessed. If you have control over the router of the network, you can increase the wireless signal by placing the router on a high area such as a counter or desk rather than have it sitting on the floor. You can also increase the signal by pointing the router’s antenna in a certain direction or placing the router itself in Read More

Computer chips are made out of numerous different components called transistors and a semiconductor such as Silicon. All of these transistors and semiconductors are squeezed onto the computer chip to maximize performance. As computer chips get smaller, engineering brings about new methods in which they can force these components onto a computer chip. What are Transistors? A transistor is the electrical component of an integrated circuit (IC) that is responsible for its computing. The transistor can be compared to an "on and off" switch. When conditions are right, the transistor Read More

Network Load Balancing Overview Network Load Balancing (NLB), included in Windows 2000 and Windows Server 2003 can be used if you need to provide increased levels of availability for TCP/IP applications. All versions of Windows Server 2003 include NLB. While NLB is automatically installed, it is not enabled. In a NLB cluster, client requests are load balanced between the servers residing in the NLB cluster, as specified by configured load balancing parameters. Servers can be configured to share the processing of client requests. NLB can also reroute any requests that Read More

WiMAX stands for Worldwide Interoperability for Microwave Access. WiMAX is a broadband wireless point-to-multipoint specification from the IEEE 802.16 working group. Unlike wireless LAN technologies such as Wi-Fi (802.11), WiMAX is designed to operate as a wireless MAN (Metropolitan Area Network). This places WiMAX in the same class as the earlier 802.16 standards, MMDS and LMDS. WiMAX Frequencies WiMAX variants operate both on FCC licensed frequencies and on unlicensed frequencies. Licensed WiMAX operates in the 10 to 66GHz range; unlicensed WiMAX operates in the 2 to 11Ghz range. WiMAX Bandwidth Read More

Your hard drive is where your computer stores the operating system and most folders and files that it uses. Hard drives have grown in capacity over the years, and as storage capacity has increased so has the amount of data one can store on his or her computer. Knowing not only the capacity of your computer’s hard drive, but also the amount of free space available, is crucial when loading large applications such as a new operating system, office applications, or large files such as video or audio. There are Read More

Windows Internet Explorer, more commonly know as IE, is a graphics based web browser developed by Microsoft and bundled as part of the windows operating system. It is the most widely used web browser today. The very first version of IE – IE 1 was introduced in 1995 as a part of Windows 95. The latest in the series is IE 8. Password protecting Internet Explorer Password protection for IE can be enabled to prevent or limit the type of online content that is viewed by users. This feature is Read More

Help desk software is used worldwide to create an efficient manner of tracking inventory, responding to customer complaints and questions, handling invoices and accounting, and everything else that goes into running a business’ frontlines. While almost all help desk programs are different from one another in slight ways, most provide the same core features. Of course, it is still vital to compare multiple help desk programs in order to find one that fits a certain enterprise. This article will serve that purpose by listing and reviewing a number of help Read More

A DHCP (Dynamic Host Configuration Protocol) server is used on networks that allow computers to be automatically configured for network communication. A DHCP server automatically assigns an IP address to a computer connected to a network from a pre-defined range of IP addresses. It ensures that no two computers on a network are assigned the same address. DHCP can be used for both Ipv4 and Ipv6 network addressing. However, lpv4 and lpv6 are considered separate protocols for each model of IP address assignments. How Does a DHCP Server Work? When Read More

Many people obtain music from illegal sources, which has crippled the recording industry. This has, of course, led to aggressive lawsuits and new laws and procedures concerning how these people and their sources are treated. The entire situation can be avoided, however, if people simply use legal music  sources instead. While the vast majority of music sources are commercial in nature, there is no shortage of websites that allow users to download free music. These websites have proper permission to distribute music files and often collect money from advertisements, although Read More
