Computer – The Need Of Modern Life

Computer – The Need Of Modern Life

Computers simply mean a machine which can compute. Let us peek into the past and find out who were the geeks who thought about having a device that could perform calculative tasks by recognizing inputs and giving the appropriate outputs.

Abacus developed in 3000 BC can be called the first ever computer as it was a simple counting device. In 1941 a German engineer Konard Zuse developed a first programmable calculator using binary math and Boolean logic. UNIVAC was developed in 1951 and the real breakthrough came in 1952 when Texas Instrument developed the Integrated Circuit. In 1964, IBM introduced a mainframe computer called IBM 360. Apple introduced Apple I in 1976 and Apple II in 1977. The Computer that is familiar to most of us in terms of looks and functionality was unveiled in 1981 when IBM introduced the Personal Computer.

The main characteristics of a Computer are:

1 – It follows and is capable of following a special set of instructions.

2 – It can execute preset list of instructions generally known as a computer program.

The basic components which are essential to make a computer are:

1 – Input Device comprising of a Keyboard and Mouse which are used for entering instructions and data into the computer.

2 – Output device such as the Visual Display Unit or the Screen, Printer etc, which lets us see what the computer has done.

3 – The Central Processing Unit which is known as the brain of the Computer where all the processing of data is done and instructions are executed.

4 – Memory is the powerhouse of the computer which stores data and instructions in it.

5 – Mass Storage Devices are those which permanently stores and retain large amount of data. The common ones are floppy drives, CD-ROMs, Hard disks etc.

Computers come in various types designed for various purposes keeping in mind different categories of its users. According to their type they have different capabilities and are priced accordingly. The most popular computer is the Personal Computer which is for personal use of a single user at one time. They come in two types; A Desktop and a Laptop. Then there is an even smaller computer known as the Palmtop which can be held in the palms of the user. While these are the smaller and personal types of computers, The Mainframe, Workstation and Supercomputers are the larger high end computers used by big organizations.

Computers can perform a wide range of functions such as word processing, Digital Audio/Video composition, Internet, Communications and Networking and Desktop Publishing. Computers word processing capability includes automatic correction of spelling and grammar mistakes. Internet is one of the greatest inventions of human beings. It connects infinite number of computers in the manner of a web.

Ungodly amounts of information are available on the Internet and facilities of communications such as messaging, audio and video conferencing are available for free. Graphic engineers are using computers for editing audio and video compositions. No media production can be completed without the help of computers. Nowadays Computers are indispensable for Banking, Railway and Flight Reservations, Education and even defense of a country. There is hardly any sector of business which does not utilize Computers. Important and critical business tasks cannot be accomplished without the help of computers.

Just like human beings, computers are also prone to diseases which are created by attack of viruses. Proper back up of all data stored in computer must be maintained to provide back up in case of storage media failure. Computers must be secured from unauthorized use by passwords and must be protected from viruses by installing anti-virus programs in them. Computers, if safeguarded and used properly can create wonders for human kind and can produce results which are unachievable without them.

Equipment You Need For Web Videos

Equipment You Need For Web Videos

So you’ve decided to make your first web video. This is a great step, especially if you are making a web video to help promote a product or service. However, there are several things that you must have in order to make your web video look professional, and entertaining to watch. Of course, the main items that you must have in order to make a web video are a digital video camera and a computer. However, the type of camera you have can greatly increase the quality of your video, or it can decrease it. While there are literally hundreds of different types of digital cameras out there that will record decent video, there are some that are way better than others.

If you are looking for a camera that will keep your web video looking professional and crisp, as well as easy to upload into your computer, you will want a hard drive camcorder. These hard drive camcorders will allow you to record stunning images, however, it is how you upload these videos into your computer for editing that makes them so great. With a hard drive camera, you are able to record video without the need of tapes or DVDs. This is made possible because the camera records information onto its hard drive. Once you have recorded everything that you need, you can simply attach the camcorder to your computer, usually through a USB cord, and then your computer begins to upload the videos into its own hard drive. After you have done this, you can then begin the editing process.

Choosing the right type of camcorder for web videos is extremely important, and if you know that you are going to be filming many web videos, than it is a good idea to invest in a decent camera that has great resolution and user-friendly exporting options.

Another piece of equipment that you will want to have is a microphone. While every camcorder comes with a built-in microphone, they will not give you the professional quality that you desire. You do not have to go out and purchase a 0 microphone in order to get good audio quality; however, you will want to have a microphone that allows you to guard wind and other types of background noises. Another reason why having a microphone is so important is because it will give you the chance to make videos that are not only pleasing to the eye, but also to the ears. Did you know that sight and sound makes up for 85% of the information that we absorb around us? This is why making sure you have a great quality camera and microphone is so important.

However, if you don’t have this last piece of equipment, than you will most likely not be able to post your videos online. The last piece of mandatory equipment for making web videos is a computer. Whether you are working with a desktop computer, or laptop, it is very important that your computer can handle the amount of CPU’s you are going to be requesting of it. However, even though you want to have your computer run smoothly, you will also want to ensure that it has enough memory to hold all of the information that you are going to be putting in it.

With many different files that need to be saved, such as massive video files, audio files and the other various types of media that will begin to accumulate onto your computer, you must ensure that you have ample memory. Many individuals that make web videos usually invest in an external hard drive. These are great accessories to have, and will keep your computer running smoothly, because the amount of memory needed will be spread out among different hard drives.

Have You Made the Switch from Desktop to Laptop? What You Need to Know…

Have You Made the Switch from Desktop to Laptop? What You Need to Know…

If you’re one of the million who have given up bulky desktop computers altogether for the sleeker, lighter, more versatile laptop, there are a few things you should consider if you haven’t already.

First, because they are portable and light, laptops aren’t inherently as secure as desktop computers when it comes to theft. And we’re not just talking about coffee shops, airports, college campuses, and the passenger seats of cars (which is where most laptops tend to be stolen). Even if you’re in the practice of leaving your laptop on your desk when you go home for the evening, your risking theft should someone break into your office suite or if a door is left unlocked. The first thing a thief would do is snatch up all the laptops. They’re valuable, they resell easily, and they’re easy to remove undetected.

The answer to this problem is simple. Attach a lockable laptop drawer to your desk. We found high-quality models at Versa Tables for under 0. Constructed of steel, these accessories bolt to the under side of almost any desk and allow for a laptop to be retracted under the desktop when not in use, and locked with a key. The back of the drawer has an opening to allow the laptop to be plugged in and charging overnight. While occupying your desk, simply pull the drawer out and use the laptop right there—it creates more space on your desk.

Second, back up your files. Because laptops are mobile, they are at a higher risk of being dropped, kicked when your laptop case is sitting at your feet, or of having something spilled on them. While the manufacturers of laptops are well aware of this, no piece of computerized machinery is indestructible. Back up your files more often either by copying them onto a jump drive or by emailing them to yourself.
Third, be sure to have the necessary accessories at your fingertips. We suggest an extra battery (kept charged), an approved extension cord, and outlet adapters if you plan to travel. An additional USB cable is always good in case you need to plug into a printer and lightweight headphones will allow you to use your laptop anywhere (and still hear live streaming video or DVDs) while maintaining your privacy and without disturbing others.

The last thing you need to know is that ergonomically, laptops aren’t as well-designed as your desktop computer probably was. With desktops, most people now use keyboard trays that adjust to the comfortable tilt and height for the user and therefore, minimize the risk of Carpal Tunnel Syndrome and other conditions caused by repetitive motion. Unfortunately, laptops pretty much just rest on your lap and if put on a desk, do not sit at the correct ergonomic height. Experts predict that with the increased use of laptops, there will be an increase in repetitive motion symptoms and potentially disabling conditions like CTS. A way to combat this is to use a laptop desk when working at home or the office. Laptop desks, often referred to as ‘Laptop Carts’ because of their mobility, are available on the market. Simply, they are height-adjustable carts designed to hold a laptop and allow the user to sit or stand while using them. They don’t provide the same ergonomic efficiency as a keyboard at a traditional desk, but they’re better than flopping down on a sofa and sitting the laptop on your lap or having to reach up to type on the laptop keyboard at a regular desk.
