Ok, so who are the people that make these gadgets? All that you would require are these two components primarily, all the rest are optional. However, we will take a closer look at these two components and a bird’s eye view of the others.
One of the largest wireless router or access point makers is NetGear. There are also others like D-link, Buffalo, Linksys and Kyocera.
There are also others who make the same products; the capacities/sizes are relatively smaller. Most of these manufacturers make both the access points as well as the cards for your computers.
Again the cards come as plug-in options, adaptable with your computer; they can also be fitted into your laptop’s USB port. Most of the laptops these days come with an inbuilt WiFi adapter. Read the rest of this entry →

If you want to do wireless networking, you need a device that will link the computer to the server over a wireless transmission system.
This is a device we call the access point. You will connect to this access point from your computer. Normally, this is the nearest access point or the strongest access point.
The word ‘strongest’ refers to the signal strength at that point! Make sure you have a wireless card on your computer or laptop. Read the rest of this entry →

If we look at how these two compare, then maybe we should start with a factor that is quite important to every one. Cost! In the case of wired networks, the costs of the equipments are much cheaper.
The reasons being that wired networks have been in the market for much longer; this has resulted in a large number of users. Equipment is also much cheaper and more rugged.
The equipment is manufactured such that it can withstand a lot of careless handling; there are a number of security features that come along with the product as a standard. But, this is not the case with wireless networks.
In the case of wireless networks, there is no cable running all over the work place; you can move around the whole office with ease. Read the rest of this entry →

The most common networking was and continues to be the wired network; however the popularity of this is waning. On the other hand, the popularity of wireless networking is on the rise simply because of the comfort it provides its users.
There is not much difference in the way a wireless and a wired network work. It is in the way the signals are carried from one point to the other that they differ.
In case of a wired network the signal is transmitted over the wire as an RF signal. In the case of a wireless network, the signal is transferred to the destination as an RF signal transmitted over the air.
As the ease of wireless networking increases, its popularity will keep growing. Read the rest of this entry →

Networking is the way computers get connected to one another. This answer seems pretty simple, doesn’t it?
In order to get connected you can use different techniques. Today, with increasing numbers of computers and laptops at home, the way you get connected is an important differentiator. It impacts the ease at which you can work at home
You can connect to the internet by just plugging in the computer cable, more commonly known as the Ethernet cable terminal, into your machine.
In the days of the desktop, you were permanently connected to the network. Today, with laptops and palmtops being used extensively, you are not necessarily rooted to one place. Therefore there is no reason why you should try to connect over a fixed line. Read the rest of this entry →

A device driver or a software driver is a specific type of computer software typically developed to allow interaction with hardware devices such as a mouse or a printer.
This software causes an interface for communicating with the device through the specific computer “bus” or communication subsystem that the hardware is connected to.
The software provides commands to and receives data from the device and, on the other end, the requisite interfaces to the operating system and software applications. Read the rest of this entry →

The words disk operating system refers to system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them.
For example, you have several files systems meant for organizing data files of all sorts. Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters such as hard disks or floppy disks.
In the early days of micro computing, memory space was often limited so the disk operating system was an extension of the operating system. Read the rest of this entry →
