Today's Featured Computer Term: Bus
A bus is a collection of wires through which data is transmitted from one part of the computer to another. You can think of a bus as a highway on which data travels within a computer. When used in reference to personal computers, the term bus usually refers to internal bus. This is a bus that connects all the internal computer components to the CPU and main memory. There's also an expansion bus that enables expansion boards to access the CPU and memory.
All buses consist of two parts -- an address bus and a data bus. The data bus transfers actual data whereas the address bus transfers information about where the data should go.
The size of a bus, known as its width, is important because it determines how much data can be transmitted at one time. For example, a 16-bit bus can transmit 16 bits of data, whereas a 32-bit bus can transmit 32 bits of data.
Every bus has a clock speed measured in MHz. A fast bus allows data to be transferred faster, which makes applications run faster. On PCs, the old ISA bus is being replaced by faster buses such as PCI.
Nearly all PCs made today include a local bus for data that requires especially fast transfer speeds, such as video data. The local bus is a high-speed pathway that connects directly to the processor.

Today's Topic: Copy and Paste Parts of a Document
You can copy part or all of a document and then paste it into another section of the same document, or into another document entirely. This allows you to quickly reuse text, images, charts or any other information without retyping.
1. Open the document and select the section that you want to copy. (Note: to select text, point to the first character to be selected, hold the left mouse button down, and drag across text; to select a graphic, right click on the graphic, left click on copy in the resulting menu)
2. While the section is selected, open the Edit menu and click Copy. This copies the selected material into a special area of the computer's memory, called the Clipboard. (Note that the selection also remains where it was in the document; it doesn't disappear.)
3. Move your cursor to the place or document where you want to paste the material that is now in the Clipboard. Click when your pointer is in the correct spot. A flashing line will appear where you clicked.
4. Open the Edit menu and click Paste.
The material that you copied into the Clipboard now appears at the spot you indicated. |
