When the computer boots up, certain amounts of information are needed to ensure that the computer boots properly. This includes hard disk types, keyboard and display type, chip set and the time and data. For example, the hard drive booting properly means that the operating system boots properly. This is important to understand because it explains why CMOS RAM is so important. CMOS (complementary metal-oxide semiconductor) RAM is a type of memory chip that has low power requirements. When in a PC, it operates by using a series of small Read More

A switch is something that is used to turn various electronic devices on or off. However, in computer networking, a switch is used to connect multiple computers with each other. Since it is an external device it becomes part of the hardware peripherals used in the operation of a computer system. This connection is done within an existing Local Area network (LAN) only and is identical to an Ethernet hub in terms of appearance, but with more intelligence. These switches not only receive data packets, but also have the ability Read More

What are Dynamic Disks A dynamic disk refers to a hard drive that can be altered at any time to include additional partitions or volumes. This differs from basic disks that only include standard and extended partitions that are setup when the disk is first formatted. Dynamic disks can handle all of the following volumes. Simple Volumes A simple volume refers to the standard volume in which computers often work with. A simple volume is basically a folder on a hard drive that holds all of the user's information. For Read More

Cat 3, short for Category 3, is a UTP (Unshielded Twisted Pair) cable designed to carry voice and data up to 10 Mbps (mega bits per second), with possible transmission frequencies up to 16 MHz. Cat 3 cable is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA). If a cable is certified as Category 3 and not just twisted pair wire, then it will have "Cat 3" printed on the shielding. Cat 3 and Cat 5 Read More

The Xbox 360 is a popular game console produced by the Microsoft Corporation. It is the successor to the original Xbox console first released in late November, 2001.

Arrays, linked lists, stacks and queues are used to represent linear and tabular data. These structures are not suitable for representing hierarchical data. In hierarchical data we have ancestors, descendants superiors, subordinates, etc Family Structure Business Corporate Structure Federal Government Structure Introduction to Trees Fundamental data storage structures used in programming Combine advantages of ordered arrays and linked lists Searching can be made as fast as in ordered arrays Insertion and deletion as fast as in linked lists Tree characteristics Consists of nodes connected by edges Nodes often represent entities Read More

Gyroscopes measure orientation, gain or maintain a specific orientation, and are based on angular momentum principles. Mechanical gyroscopes are typically made up of a spinning disk or wheel with an axle that can take any orientation. Large changes in angular momentum affect the axle more than the external torque’s effects due to the gyroscope spin’s high rate. Gyroscopes are commonly used to stabilize airplanes and helicopters, in ship navigation, naval weapons guidance systems, and tunnel mining. Modern gyroscopes can be linked to global positioning system-based devices in order to obtain Read More

PDFs are files that are easily transferred from one person to another because of how many computers come with a reader built in for the format. One of the features that people can do is combine PDF files together to make one larger PDF. A reason for doing this would be if you had a series of small reports that you wanted to combine into one larger one. Combining them together takes a few clicks and then the new PDF can be sent. The first step is to save all Read More
