What Is 64-bit Computing?

32-bit refers to the number of bits (the smallest unit of information on a machine) that can be processed or transmitted in parallel, or the number of bits used for single element in a data format. The term when used in conjunction with a microprocessor indicates the width of the registers; a special high-speed storage area within the CPU. A 32-bit microprocessor can process data and memory addresses that are represented by 32 bits. 64-bit therefore refers to a processor with registers that store 64-bit numbers. A generalization would be to suggest that 64-bit architecture would double the amount of data a CPU can process per clock cycle. Users would note a performance increase because a 64-bit CPU can handle more memory and larger files. One of the most attractive features of 64-bit processors is the amount of memory the system can support. 64-bit architecture will allow systems to address up to 1 terabyte (1000GB) of memory. In today's 32-bit desktop systems, you can have up to ...

The Difference Between Hubs, Switches and Routers

Some technicians have a tendency to use the terms routers, hubs and switches interchangeably. One minute they're talking about a switch. Two minutes later they're discussing router settings. Throughout all of this, though, they're still looking at only the one box.  Ever wonder what the difference is among these boxes?  The functions of the three devices are all quite different from one another, even if at times they are all integrated into a single device. Which one do you use when? Let's take a look... Hub, Switch, and Router Defined Hub  A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Switch  In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the ...

How to Convert PPS to PPT

Files with .pps and .ppt extensions are both created with Microsoft PowerPoint software. A .pps file opens directly as a PowerPoint slide show and automatically closes after the presentation is complete. These files are for presentations only and do not allow any editing. Conversely, .ppt files open in PowerPoint and allow the user to edit and make changes to the presentation slides. Converting a .pps file to a .ppt file is quite simple, does not require any special software and takes just a few minutes to complete with Microsoft PowerPoint Instructions Make sure the .pps file is saved on your computer in a location that you know how to access easily. Open Microsoft PowerPoint. PowerPoint is usually found by accessing the "Start" menu and selecting "All Programs," and then the "Microsoft Office" folder. In PowerPoint, go to the "File" menu and select "Open" from the drop-down list. A prompt will appear, asking you which...
