Processor

Processor

The CPU, or the central processing unit, also known as a processor for short, is the brain of every computer.The CPU executes any calculation or process made by the computer.
The processor uses bits that have either a value of 0 or 1 for all of its calculations ("bit" is short for "binary digit"). Computers store, process and retrieve information by using strings of bits, such as, for example "1011001." All computer programs like Internet browsers, word processors and image manipulation software must be processed by CPUs.

Microsoft Windows and Linux Hardware Requirements

Microsoft Windows and Linux Hardware Requirements

Microsoft Vista's Hardware Requirements

Initial reports indicated that Microsoft Windows Vista (Longhorn), Microsoft's next major operating system scheduled for release in 2007, had exceedingly high minimum hardware requirements. However, they've dropped many of Vista's features. So far Microsoft indicates the minimum requirements for Windows Vista correlate with many PCs being sold today. It appears the new Aero Glass user interface will require the highest end video hardware available. 64 MB (128+ MB recommended) RAM on a high bandwidth AGP 8X or PCI Express 16-lane bus is required for the full "Aero Glass Experience."
One Microsoft Windows Vista beta tester reported "there are about 47+ process running. It uses about 150mb more ram then XP. And it takes an extra 8 seconds to start." (source no longer available and web archive missing: http://www.theartofennui.com/36/windows-vista/) That's with no applications running, only the operating system. Microsoft Windows Vista is obviously much less efficient than Microsoft Windows XP. The loss in efficiency is at least partly due to new graphics. The value of the trade-off between graphics and performance will be determined by each user. It remains to be seen if Windows Vista without Aero Glass is more efficient than Windows XP.

Average Microsoft Vista Hardware Requirements (Microsoft Recommends)

Processor: Dual-core CPU running at 4 to 6GHz

Memory: 2 GB to 4 GB (Double minimum is average)

Hard disk: Up to a terabyte

Networking: 1 Gbit, built-in, Ethernet-wired port and an 802.11g wireless link

Video: Graphics processor that runs three times faster than those on the market today (mid 2003)

(Foley, Mary Jo. "Longhorn to Steal Limelight at WinHEC." Microsoft Watch 30 Apr 2004)

Microsoft Windows Vista's hardware needs may be so high that many people will not be willing to make the investment for the upgrade. In 2004, Credit Suisse First Boston predicts "there is some risk that PC sales will slow down materially in calendar 2006 in front of Longhorn that we are now modeling as a 2007 event. We fear that heavy hardware requirements for Longhorn will discourage buying." ("Microsoft's Longhorn May Discourage PC Buying." Forbes 18 Aug 2004)

Windows XP 64-Bit Edition

The 64-bit version of Windows XP has a minimum requirement of 1 GB RAM. Microsoft® usually recommends double the minimum, although for now there's no recommended amount. From past experience, having twice of what Microsoft recommends is necessary for typical use. Therefore 4 GB of RAM may be necessary to properly run WinXP 64-Bit Edition.

Linux Hardware Requirements

Typical minimum requirements for a Linux distribution:

Processor: Intel: Pentium 1-4 or Xeon; AMD: Duron, Athlon, Athlon XP, Athlon MP, Athlon 64, Sempron or Opteron

256 MB of RAM (512 MB recommended)

500 MB of disk space (800 MB to 2 GB often required when including a basic set of applications)

Network Topologies

In computer networking, topology refers to the layout of connected devices. This article introduces the standard topologies of networking.

Topology in Network Design

Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find a ring topology there.

Network topologies are categorized into the following basic types:

bus

ring

star

tree

mesh

More complex networks can be built as hybrids of two or more of the above basic topologies.

Bus Topology

Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message.

Ethernet bus topologies are relatively easy to install and don't require much cabling compared to the alternatives. 10Base-2 ("ThinNet") and 10Base-5 ("ThickNet") both were popular Ethernet cabling options many years ago for bus topologies. However, bus networks work best with a limited number of devices. If more than a few dozen computers are added to a network bus, performance problems will likely result. In addition, if the backbone cable fails, the entire network effectively becomes unusable.

Ring Topology

In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device breaks the loop and can take down the entire network.

To implement a ring network, one typically uses FDDI, SONET, or Token Ring technology. Ring topologies are found in some office buildings or school campuses.

Star Topology

Many home networks use the star topology. A star network features a central connection point called a "hub node" that may be a network hub, switch or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet.
Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computer's network access and not the entire LAN. (If the hub fails, however, the entire network also fails.)

Tree Topology

Tree topologies integrate multiple star topologies together onto a bus. In its simplest form, only hub devices connect directly to the tree bus, and each hub functions as the root of a tree of devices. This bus/star hybrid approach supports future expandability of the network much better than a bus (limited in the number of devices due to the broadcast traffic it generates) or a star (limited by the number of hub connection points) alone.

Mesh Topology

Mesh topologies involve the concept of routes. Unlike each of the previous topologies, messages sent on a mesh network can take any of several possible paths from source to destination. (Recall that even in a ring, although two cable paths exist, messages can only travel in one direction.) Some WANs, most notably the Internet, employ mesh routing.

A mesh network in which every device connects to every other is called a full mesh. As shown in the illustration below, partial mesh networks also exist in which some devices connect only indirectly to others.
