How to Share Files Between Computers

File sharing in a network is one of the important reason why the computers are connected. But many of us who have recently setup a network, are often unable or find it difficult to share the data. In other words, the hardware part is done, the computers are connected, but how to get the network into action? Sharing files between computers is not a difficult task. Let us go through various considerations and steps that are required to undertake this task.

Prerequisites

Here it is assumed that you have already completed the hardware part for creating your network. Now, let us proceed to the other prerequisites. You need to first consider if the IP address in all the systems is set up in the same scheme. Each IP address should be different from the other, but the scheme should be same. It implies that, the IP address of the computers in a network should be in the same class. It has basically four classes: Class A, B, C, and D. In general, Class C is the most used scheme for the local area networks or home networks. It will be something like 192.168.254.x, where x can be any number. The x is the only number that you can vary and it can be anything from 1 to 255. Once you have assigned a unique IP address to all the computers, your next step is to provide a unique name to each of them.

The process is very simple for all the systems running on the Windows operating system. Just right click on the My Computer icon and select Properties. For Windows Vista, just click on the settings tab and then on ‘change’ and for Windows XP, click on the computer name tab and then on ‘change’.

Computer Restarts after Shutdown

Like all other pieces of technology, a computer also suffers from various issues from time to time which are very hard to attribute to one single cause. There are so many components embedded inside a machine that it is very hard to predict what can go wrong at any given time, and even when something does go wrong, it is very difficult to find the exact cause. People who are clued up about the workings of a computer and people who are professional computer repairmen follow a fixed and orderly method of checking problems, since this is the only way to ascertain the actual issue.

One of the most annoying things that can happen to a computer is that it simply refuses to shut down. This is a problem that Windows XP users, more than anyone else, have faced over the years and this ultimately leads to simply turning the power source off which can result in loss of data and other issues. If you find that your computer restarts itself after shutdown then you need to take the situation very seriously, since the underlying cause of the problem can inevitably lead to more serious problems as well. People who do not know much about the workings of a computer may not be able to do much about this problem, but the causes mentioned here can be investigated by someone who is not completely ignorant about such things.

Causes of Automatic Restart

Common causes of computers restarting by themselves are computer viruses, computer overheating, computer hardware defects, computer hardware incompatibility and computer driver problems. All of these issues have their own specific solutions that must be applied in order to fix the problem. You should install an antivirus software or update the existing one, you should use the computer in a

How to Build a Gaming Computer

Gaming has been taken to a whole new level today, with 3D graphics, great storylines, and unmatched action scenarios. If you take your gaming seriously and are planning to buy a new PC, exclusively for gaming, why not think about building one on your own. Buying gaming laptops from brands like Alienware can cost a fortune, but you can get the same functionality, offered by these branded machines, by building a custom-made gaming computer, with the combination of the best hardware. It is a sensible and economical choice. The added advantage is that you get to learn all about hardware assembly. This Buzzle article is short guide on building a gaming computer from scratch. I will primarily talk about choosing the various hardware parts, required for assembly. You will need to figure out how to assemble it on your own, by reading through the manuals that come with the hardware equipment. Still, I provide a basic overview of assembly.

A Short Guide

To know what features and kind of components you need, to build your gaming computer, study the configurations offered by top brands and the system requirements specified on game DVDs. This will give you an idea about the minimum requirements that you need to take into consideration while choosing computer parts.

Choose a High Performance Computer Processor
Intel and AMD offer a range of computer processors for you to choose from. For gaming, you want a chip with high clocking frequency, high cache size, and a high FSB clocking frequency. The best processors are the Intel i7 and AMD Phenom X II lines right now. If you don’t want to go for a high-end line, the Intel Core i5 line is a good and affordable choice for building a mid-range gaming computer. Here are

High CPU Usage Problem

If you are experiencing such difficulties on your computer, then the decreased speed of your machine can lead to a lot of confusion. This is something that happens quite frequently, and there are a variety of reasons that may lead to abnormally high CPU usage rates.

The first thing you need to know is how to check this rate on your machine. You can do so by pressing ‘Ctrl + Shift + Esc’, or by pressing ‘Ctrl + Alt + Delete’, and then clicking the ‘Task Manager’ option. In the subsequent window that opens, you need to click on the ‘Processes’ tab. This will show you the rate of CPU usage of all the applications that are currently running on the computer. You can also double click on the ‘CPU’ option, and you will see all the applications in ascending or descending order of the usage rate.

A high usage problem will be evident from this window, and you will need to fix this immediately. If you fail to do so, your machine will continue to run at an excruciatingly slow pace. Also note that this technique is useful only for people using Microsoft Windows.

Causes and Preventive Measures
There are a load of viruses and malicious software that can harm and affect your computer by different ways. One of the most common effects of these programs, is to gain control of your CPU usage, and involve it in a completely meaningless task. Note that high usage with no programs running is a clear indicator that your machine has been breached by a harmful program.

In order to solve this difficulty, you must purchase an effective antivirus software, and upgrade it from its official website on a regular basis.

Another cause is a faulty program, or some sort of a damaged file. Though,

How to Reset Computer to Factory Settings

It is a very basic task to know how to reset computer to factory settings. While it takes a pretty long time, you can be assured that anyone can do it. It is often a last try to get your PC to work properly as before. Bear in mind that while this process works for some, it may or may not work for the other. If it does, well and good; if it doesn’t, it is time to invest in a new PC instead of messing about with the restoring again. This article will give the main reasons and how to go about doing it.

The Need to Reset
In case of a virus attack on your machine, sometimes, the best way of getting rid of it to reset the device to default settings. As it cleans out the whole drive, it cleans out the viruses as well.
The second common reason is, may be your machine has gone too slow or isn’t running properly.
If you are looking to sell your old PC, then again, you would want to retain the factory settings so that the new user gets a clean disk. It is one of the answers to the question how to clean computer hard drive.
With a CD

If you happen to still have the CD, which came with your machine when you purchased it, this job becomes very easy. Here’s how to do it with a CD.
Get a backup of all your important files on a DVD or a USB drive or your friend’s hard disk. This is because, this process will erase your drive, and you may end up losing some very important documents. So, get a backup of your stuff first.
Now, insert the CD in the CD drive. The PC will then

Basic Computer Security Tips

Everyone talks about computer security i.e being secure online but how many of us actually practice the effective security tips? Then when hackers or viruses attack, we look around to attach blame. Well, prevention is better than cure, so it pays in the long run to secure your system in advance.

Tip #1: Set up user accounts
One computer, many users, is a security disaster waiting to happen. Your files and data are your personal, private content and should be protected accordingly. To prevent other users from seeing or accessing your data, set up user accounts on your PC. A user account shows an individual’s specific data and not what is present on the entire system. It also specifies privileges on shared data, such as deleting/editing operations and what software can be installed on the machine.

This feature is especially useful when kids and adults use the same machine. What if your child accesses your important work files and deletes them by mistake? With a separate user account, he/she can only view certain files and cannot modify or delete them. Even if you are the sole user of the PC, set up a guest account, in case someone else needs to use the computer.

Tip #2: Secure your wireless network
With wired Internet access, there’s little risk of someone encroaching on your network. But wireless networks do have holes in their security, so as the owner of the network, you need to be vigilant. Setting up password-protected network access is the first step. You need to assign a network name and password to your Wi-Fi network. Use the latest wireless encryption methods like WPA or WPA2. Do not reveal your network password to others.

Tip #3: Arm your computer with an anti-virus program
The best defense is a good

Types of Computer Security

Computer security is that branch of information technology which deals with the protection of data on a network or a stand-alone desktop. As every organization is dependent on computers, the technology of its security requires constant development. Here are the different types of computer security.
Hardware Security

Threat
Even if the computer is not plugged into a network, a person can open its cabinet and gain access to the hard drives, steal them and misuse or destroy the data saved on them or, damage the device altogether. It is also necessary to remember that in case one dissembles his computer hardware, the risk of losing coverage of warranty becomes very high.
Protection
The security of computer hardware and its components is also necessary for the overall protection of data. If a stand-alone system contains some important or classified information, it should be kept under constant surveillance. Locking system for a desktop and a security chain for a laptop are basic security devices for your machine. Certain disk locks are available in various sizes, which control the removal of the CPU cover protecting internal components of the system.
For example, you will find disk/tape drive lock, computer case lock with cable and padlock, security cables, etc. A disk lock guards all the internal access points located on the CPU and protects them.
Software Security

Network Security
Computer networks are an integral part of any organization these days, as they facilitate the free flow of data and services to the authorized users. However, such networks also pose a security threat in case the data is classified and confidential, thus making network security a vital necessity.
Threats
As the data is available only for authorized users, it is possible for hackers to pretend to be one, by providing the correct user name and

Computer Network

A computer network may be defined as the coordination or interconnection of a number of individual computers. It is established by the network layer in the Open Systems Infrastructure model, popularly known as the OSI model. In a broad sense, computer networks can be classified on the basis of size, structure, mode of connectivity, topology, etc.

Computer Networks Classification

Network Size
Taking into consideration the size of the implemented network, networks are classified into three main divisions; namely, the Local Area Network (LAN), Wide Area Network (WAN), and the Metropolitan Area Network (MAN). In certain fields, they are further classified as the Personal Area Network (PAN), Campus Area Network (CAN), and the Global Area Network (GAN).

LAN: A network of computers which covers only a small area, like an office or a building, can be referred to as a Local Area Network (LAN). In this case, all the individual computers have a common protocol layer for their connectivity with the basic functionality taking place at the network layer. In general, LANs are based on Ethernet technology.

WAN: The Wide Area Network (WAN) is basically an extension of the Local Area Network, except for the fact that the size of the network extends to a very large area. The major functionality of the WAN takes place at the three lower layers of the OSI model; namely, the network layer, data link layer, and the physical layer.

MAN: The Metropolitan Area Network (MAN) is a combination of two or more individual Local Area Networks, with the criterion that the boundary of the network should not exceed the city limits. It integrates the network as a single unit within a city.

PAN: The Personal Area Network (PAN) is the smallest of all networks, with most of these networks not exceeding a size

Home Computer Networking Tips

The first thing that you need to decide while planning out your home network is if your network is to be wired or wireless. The concept in each case will remain the same, wherein all your computers will connect up to a central router, which will negotiate the connections to your ISP through a cable or a DSL modem.

It is a common fact that a wireless home network provides much more convenience than a wired network. Wireless networks do not require cabling, and allow users to move from one room to another with freedom. However, wired networks are more secure and reliable, and if you can reuse the existing phone lines or the electrical wiring, then the cost of installing new cables is reduced drastically.

Wired Home Network

In the case of wired networks, the entire setup is known as a Local Area Network (LAN), wherein small bundles of cables are used, making the network available in every room of your house. These cables can be used for a phone line or a computer connection. Usually, a minimum of one Ethernet cable is required in a room. A standard bundle of wire contains four cables:
Cat5e Ethernet cable for a computer
Cat5e Ethernet cable for a phone
A coaxial cable for a television
A coaxial cable which will provide input from a DVD player
The cables lead to a common area where the phone lines can be split and the computer ports can be patched to a panel with jacks. Now, each computer is patched with a short Ethernet cable into the network router to gain access to the Internet.

Wireless Home Network

In the case of wireless networks, the entire system is known as Wireless Local Area Network (WLAN). This type of network has gained such immense popularity over the last

For Geeks, Gamers, and Power Users, a Custom Computer is Best

Geeks, online gamers, and power business computer users, such as graphic designers and photo/video editors, generally have a closer relationship with their computers than the average user. In fact, they really have to. In order to get the most out of modern interactive video games, gamers need processor speed, memory, and killer audio and graphics. Designers and photo editors, along with other power users, can do without the hardcore gaming video, but still need the muscle that comes with serious processor and memory power, as well as a more enhanced video/graphics card than a standard business user. For those who are merely geeky, having a workhorse box is simply a way of life.

With that said, it just makes sense that users that fall into one of these categories actually build their computer themselves, or, if they’re not quite that into the nuts and bolts of computing, but need customized options, have someone else do it. While it’s true that there are a number of customization options available from computer manufacturers, most of the boxes that result are actually only ‘semi-custom’ computers in that you don’t have absolute control over all the components that go into the computer. For this reason, the truly custom box is the answer.

The Case―First Impressions are Important

In reality, the only thing a computer case has to do is protect components and accommodate the fans, heat sinks, power sources, and other ‘guts’ of the computer. But modern computer cases actually can go further than that, with some separating components into different areas of the case, and resulting in a more efficient functioning of the computer as a whole. Such compartmentalization leads to cooler internal temperatures and greater ease of use. If you’re not inclined to go with one of these cases, which are actually quite
