Computer Network Overview

Computer networking or data communication is a most important part of the information technology. Today every business in the world needs a computer network for smooth operations, flexibly, instant communication and data access. Just imagine if there is no network communication in the university campuses, hospitals, multinational organizations and educational institutes then how difficult are to communicate with each other. In this article you will learn the basic overview of a computer network. The targeted audience of this article is the people who want to know about the network communication system, network standards and types.

A computer network is comprised of connectivity devices and components. To share data and resources between two or more computers is known as networking. There are different types of a computer network such as LAN, MAN, WAN and wireless network. The key devices involved that make the infrastructure of a computer network are Hub, Switch, Router, Modem, Access point, LAN card and network cables.

LAN stands for local area network and a network in a room, in a building or a network over small distance is known as a LAN. MAN stands for Metropolitan area network and it covers the networking between two offices within the city. WAN stands for wide area network and it cover the networking between two or more computers between two cities, two countries or two continents.

There are different topologies of a computer network. A topology defines the physical layout or a design of a network. These topologies are star topology, bus topology, mesh topology, star bus topology etc. In a star topology each computer in a network is directly connected with a centralized device known as hub or switch. If any computer gets problematic in star topology then it does not affect the other computers in a network.

There are different standards and devices in computer network. The most commonly used standard for a local area network is Ethernet. Key devices in a computer network are hub, switch, router, modem and access point etc. A router is used to connect two logically and physical different networks. All the communication on the internet is based on the router. Hub/Switch is used to connect the computers in local area network.

Hopefully, in this article you may have learnt that what a computer network is, how important it is in our lives, what are different network devices, standards, topologies and communication types.

Computer Virus Definition: 5 Signs You Have One

If your computer has been running slow or just not performing as well as it did when you first purchased it, you owe it to yourself to find out the cause of your problem. One possibility is that have a computer virus. Viruses can wreak havoc on your computer’s performance, and it is important that you know what you are up against. Here is a “computer virus” definition, along with 5 signs you have one.

What a Virus Is:
A computer virus is a program that can copy itself and spread across one or more computers when they are connected to a network without the knowledge of the user. Viruses can be particularly tricky to remove from your computer because they can self-modify or change over time as they copy themselves.

Fortunately, viruses can only spread across multiple computers if an uninfected computer is connected to a network, or if the computer gets connected to infected media such as a USB drive or a CD.

Do you suspect your computer might be infected with a virus? Look for these tell-tale signs:

1. Computer is running more slowly than usual:

If your computer runs slowly upon start-up, you may have a virus. Common signs are having to wait a long time to perform simple tasks such as checking e-mail or opening files. In really serious cases, your mouse pointer may even lag as it moves across the screen.

2. Locks up or crashes frequently:

Does your computer frequently just stop working or otherwise lock up, causing you to have to restart your computer? This phenomenon is also called freezing or freezing up. If your computer locks up often and/or suddenly, a virus could be the culprit.

3. You cannot access your disks:

If you are having trouble accessing your internal hard drives or external disk drives, your computer may have a virus. For example, if you click on your directory and cannot gain access to your disks, this is a tell-tale sign you may have a virus.

4. You cannot print items correctly:

Printer performance an also be affected by the presence of a virus. For example, if your printers are not accessible or if the printing results are not satisfactory, this could be a sign of a virus at work.

5. Your anti-virus software is disabled for no apparent reason:

Most computers ship with anti-virus software pre-installed. The best anti-virus products should be more than sufficient in keeping your computer protected. However, you know you have a serious problem if your anti-virus software itself seems to be repeatedly disabled upon start-up or when you try to run a virus scan. The most dangerous viruses can actually try to block your anti-virus software from working properly (for obvious reasons), which effectively renders your computer open to all potential invaders.

Viruses are not the only things that can cause performance problems for your computer. Other common causes are malware, adware, spyware, and registry problems. If your computer is not performing properly, you should explore all possibilities, including these other common causes of degraded performance.
