Sep 10th
Computer software will be the phrase used to describe a set of directions, or even a program, that lets a computer know what it’s meant to complete. Hardware refers to issues just like the computers themselves, monitors, printers, disk drives and other pieces which can be hard, meaning strong and tangible. Programs are not tangible and are given the title software. You will find a number of types of software but the 3 most common are application, programming and program.Computer Softwares – Acquiring To know The basics
Computer software will be the phrase utilized to describe a set of instructions, or even a plan, that lets a computer know what it’s supposed to do. Hardware refers to issues just like the computers on their own, screens, printers, disk drives along with other pieces which can be tough, which means solid and tangible. Programs are not tangible and are given the title software. You will find various types of software however the 3 most prevalent are application, programming and method.
Operating systems, gadget drivers and utilities are all examples of method software. An working method is basically like the commander from the computer and organizes all of the actions that take location. One of its numerous jobs is to act as an interface involving the consumer and all of the hardware. Also, it distributes program sources for the application software.
Printers, monitors, keyboards and mice are devices that need a machine manager. Each gadget has its personal driver that shops all the details that the computer requirements to run the device correctly and also to its fullest capability. For example, a keyboard driver provides the computer all the needed data to acknowledge and correctly carry out the function of every single keystroke.
Basics of Computers – Software & Hardware
Jul 1st
A computer is a general purpose machine capable of making complex calculations at extremely high speeds. Nowadays it seems that almost every device has a computer in it.
A computer is a combination of hardware and software. It has several components and they include the monitor, the CPU chassis, the mouse and the keyboard.
Components of a computer
Computer Monitor
The monitor is a device used by the computer to display texts and images. A few years ago almost every computer monitor used a Cathode Ray Tube. But these days, flat panel systems are getting more and more popular.
Keyboard
Keyboard is an input device used to input data into the computer. There are many different keyboard designs.
The Mouse
The mouse is another input device used to ‘point and click’. In the days of the DOS operating system, it was possible to operate a computer without mouse.
But the advent of Graphical User Interface has made mouse a very important input device.
The CPU Chassis
The CPU chassis or the CPU case houses the hard disk and other hardware components like disk drives, motherboard etc.
Hardware
A computer’s hardware components are the parts you can see and touch. The smallest hardware component in a computer is a chip. A computer chip is composed of layers of wires and semi-conductors. The semi-conductors in a chip are configured to represent either a 0 or a 1 when electricity passes through them. The hardware components of a computer include Motherboard, Basic Input Output System (BIOS), Central Processing Unit (CPU), Memory (RAM), Disk Drives, Sound Processor, Video Processor, Floppy Disks, Hard Drives, CD-ROMs, DVD-ROMs and Adapter Cards.
Computer Software
Software is a set of instructions telling the computer how to process, store and retrieve data.
Internet Marketing Basics – Add an Email Address To Your Domain Name
Feb 16th
When trying to build up your own website it is important that it should look as professional as possible. If you have already made the effort to purchase a domain name in the first place – it is definitely worthwhile to have an email address linked to it.
Nothing looks as professional as having an email address that is linked to your domain name as it gives it a very polished and professional look.
In this article I will show you how easy it is to add an email address linked to your domain name.
Before I begin however – I want to quickly clarify one thing.
There are 2 kinds of emails. Internet and Domain based.
What’s the difference?
1. Web Based Email
This is usually a free service. The most popular ones are Yahoo, Gmail and Hotmail.
To read your emails, you will first need to log into your internet account and then check your messages.
Although there is nothing wrong with using these emails, if you are trying to project a more professional image, it is best to create an email address linked to your domain. Additionally, you will find that domain based emails are generally much easier to remember!
2. Domain Based Email
Once you have bought a domain name, you can subsequently attach a relevant email address to it. For example Bob @vintagecars.com.
Setting up a domain based email is easily done via your hosting account. You will also be able to forward all your emails directly to your computer (Nescape, Outlook) and access them directly from there.
This is how to do it!

The Basics of Network Security
Jan 14th
A network is two or more computers linked together in order to share data. From a security standpoint, the problem with networks is that unauthorized individuals might also be able to access that data. Network security is a term that encompasses your overall system for keeping your network as impenetrable as possible, be it hardware, software, or company policies.
Whether your network consists of two computers or two hundred computers, there are certain basic security measures you should have in place. Most of these measures aren’t complicated or expensive, and they don’t require any particular expertise in networking or computer security.
One of the most basic steps for securing your network is to have anti-virus software in place. Anti-virus software periodically sweeps your computer looking for known viruses. You can also choose to run a anti-virus test at any time. Once run, the software generates a report that lists the viruses detected. You are then able to select which, if any, of the viruses detected you want quarantined and removed. It’s more important that you keep your software up to date because new viruses are created and released every day.
Next, make sure you have a firewall in place. A firewall is like a gatekeeper. It’s a hardware/software combination that allows you to decide what goes in and out of your network. You determine the “trust level” to which your firewall is set. The trust level dictates which network connections will be automatically allowed and which will require specific permission. Firewalls come with a “default” setting which is unlikely to be stringent enough to meet your security needs. For optimum security, you should always manually set the trust settings to a higher degree of scrutiny.
Network Security Basics For Businesses
Jan 7th
Like any new technology, security threats are constantly evolving and up-to-date network security is vital to businesses of all sizes. In order to meet this challenge, you must first understand and acknowledge the threats. Quite often business owners push network security issues down the priority list, and in many cases network security is not a concern at all. But what if one of your servers gets infected by a virus and must be taken down from the network, cleaned and restored to the previous state? How great would be the financial cost, downtime, and hassle be to get your systems back online?
Protect your Network
Computer and network security is not only about the hard- or software that you use, but also about the human sitting in front of it. A user who honestly believes that the bank of Nigeria wants to offer them 12.6 Million US Dollars will click their way through every “Are you sure?”, “Allow access?” or “Confirm security exception?” popup that the operation system, browser or virus scanner throws at them to get it. By doing this, the user has effectively invited trouble into the network. Social engineering is the unifying threat that puts all computers and their users at risk.
One way to protect your network is to filter out all undesirable traffic at the edge of the network in your internet gateway, before it can reach all your workstations and users. This is a good primary line of defense. There are various internet management suites available that allow you to control your network traffic. A professional network security suite should at least allow you to:
