When you are looking for the right notebook, it is important to know where you are going to work with it. Do you want to use it on the road? Choose a model with a special energy saving 'mobile' processor, a good battery and a reasonably small display. This will allow you to work longer with the same battery and saves you the trouble of carrying around a large display that consumes a lot of precious battery power. Or will you be using you notebook mainly in places where you will have access to a power outlet? Then choose a desktop processor (more processing power for less money) and an ordinary battery, this will save you a lot of money, which you could spend on a bigger screen, you'll work faster because you can view more information at once and it's great for multimedia!<br>, Personal Computers, PCs for short, are computers for personal usage. They always have the following components:<br>- A processor (CPU), this is the heart of your computer, where the data processing is done.<br>- Memory (RAM), this is very fast memory in which temporary data is stored before being processed by the processor.<br>- Motherboard, this is the component that connects all the different parts of your computer. Often it has some integrated components like a sound card, enabling your computer to play sound, or a network card, to connect your computer to the network.<br>- Video board, this is the part of your computer that is responsible for the graphics processing. Micro ATX motherboards often have an integrated video board. Those integrated video boards are generally not very well suited for playing games, but good enough for watching movies.<br>- Hard disk, this is the permanent memory of your computer where your data is stored.<br>- An optional DVD/CD player/recorder for reading/writing DVDs/CDs., Servers are extra powerful, extra reliable computers that have been specially designed for server applications. For example serving a website, a large database or shared storage space to a lot of users. Servers are often not very quiet and deliver hardly any graphical performance, which makes them not suitable for use as personal computer. If you need a lot of servers, choose a rack mountable model. Those models need less space and your server room will remain tidy., Small-sized, low-cost, light weight, lean function subnotebooks optimized for Internet access and core computing functions (e.g., word processing) — either directly from applications installed on the netbook itself or indirectly, via cloud computing., The Random Access Memory (RAM) is an important part of computers, servers and other electronic devices. Generally it is much faster than the permanent storage memory of your device and all information stored in it will be lost when you switch off your device. Extra RAM is often an affordable and efficient way to upgrade your slightly outdated device, so you can use it another year. For an ordinary PC to function properly you need at least 512 MB of RAM nowadays., The Central Processing Unit (CPU) or (micro) processor is the part of a computer where most calculations take place. In terms of computing power, the processor is the most important element of a computer system, so the performance of a computer is highly dependant on the performance of the processor. For quite some time the performance of a processor has been determined by the number of MHz the clock speed was, but nowadays clock speed doesn't have so much to do with the speed of the processor anymore. One of the best ways to compare different kinds of processors, is to look up benchmarks on the internet. Please be careful to buy a processor that is compatible with your motherboard, i.e. fits in the right socket., The video card - is the complete graphical subsystem of the PC. It is responsible for the quality and speed of video processing. For users that wish to play games or work with multimedia applications, it is especially important to have a video board with a high performance graphics processor and enough memory., The motherboard or mainboard is the component that connects all the different parts of your computer. Often it has some integrated components like a sound card, enabling your computer to play sound, or a network card, to connect your computer to the network. The standard form factor (size) for motherboards is ATX, you need at least a midi-tower to fit one of those in. Micro-ATX motherboards are often more complete and have more onboard devices, like a video board and fit in smaller cases, but are generally less expandable. , A sound card or audio board allows computers to play and record sound. If you have a 5.1 or 7.1 audio board, you can connect your computer to your home cinema set for the real cinema experience, with full surround sound, whilst playing games or viewing DVD's., A multifunctional is really an all-in-one device; it is both a scanner and a printer, and often even has a facsimile function.

Moreover, you will be able to work faster and more efficiently by using the device's convenient special functions., Laser printers are devices that print high quality text or illustrations fast. They do so by very accurately applying toner (a kind of ink powder) to the paper and then heating the paper so the toner will melt and stick to the paper., Inkjet printers are the most suitable printers for home and small office use. They are generally not as fast as laser printers, but make prints of very high quality and are quite affordable., Create your own, professional looking labels fast and conveniently with one of these label printers!, Photo printers allow you to print digital photos, often they can even print directly from a digital camera, so you do not even need a computer to print your photos. Having such a printer at home, you can forget the photolabs!, A computer system that has a connection with the Internet or has contact with the rest of the world in some other way needs a virus scanner. The effects of virusses vary from a harmless joke to slowing down your computer, the deleting or corrupting of data, sharing your sensitive data with the rest of the world or granting hackers access to your computer. Virusses spread mostly through e-mails and programs, and every day new ones come out. Most virusses are written for popular operating systems, and older versions of software tend to have security problems, so make sure you always have a working virus scanner with the latest virus definitions installed on your computer and preferably also the latest version of your operating system of choice., The operating system is the program that gets started first when you switch on your computer or server.

Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resourses with your entire home or office network., A NIC or Network Interface Card is a circuit board or chip, which allows the computer to communicate to other computers on a Network. When connected to the network, computers can share websites, files, printers and other resources. The most popular networking standard at the moment is Ethernet, which one can recognize by the rectangular connectors with eight wires in them. Wireless network with the 802.11b and the faster 802.11g standard is also increasingly popular, both at home and in the office, though it is not yet as fast as wired (ethernet) network. A public place where you can use wireless internet is called a "hot spot". , With a router you can connect networks. Most people will use a router to connect their local (wireless) home or office network (LAN) with the Internet. The router makes sure that all computers on the local network can connect with one another, with shared resources and with the Internet and can be configured to forward requests for connections from computers on the internet to the appropriate local computer. In order to connect your local network to the internet via an ADSL or cable, you also need an (Ethernet) ADSL or cable modem if it is not built-in in the router, which is most likely to be the case., Call your friends, business parners or customers with one of these great telephones!, Hard disk drives are today's fastest permanent storage media and have a large capacity. For this two reasons they are the most used storage medium in computers and servers. When buying a new hard disk, there are three important things to consider:<br>- The connection of the disk to the computer or other device you will be using it with has a big influence on the speed with which data can be read from/written to the disk. Make sure the connection of the disk you buy is compatible with your computer!<br>- The rotational speed is also important for the speed with which data can be read from/written to the disk and determines the time it takes to find a file on the disk.<br>- Last but not least, the storage capacity of the disk, i.e. the amount of data that can be stored on the disk., Flash memory comes in different types and is used by all kinds of products, e.g. cameras, MP3-players, telephones. The great advantage of flash memory is in the fact that it has no moving parts, so it is shock resistant and hardly wears. It is also very small and very light, which makes it perfect for use in portable digital devices., With these drives you can read and record DVDs and/or CDs in all kinds of different formats. Please notice the difference between DVD+R and DVD-R when buying a DVD burner, often drives can write only to one of those two media types, sometimes to both. When you buy a drive that only supports one type, you will always have to be careful to choose the right writable DVD discs at the shop. Newer DVD drives also support writing to Dual Layer DVDs. This kind of discs have a storage capacity of 8.5 GB instead of the usual 4.7 GB.
