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.

Success at the workplace (5 )

Success at the workplace

It’s difficult to believe that there are people in today’s workforce that do not recognize how to make use of a computer. In today’s culture, being computer system illiterate amounts being functionally illiterate. Undoubtedly nobody reading this write-up is computer system uneducated, however possibly you understand someone who assumes they can prevent computer systems and also still be effective at work.
Let me inform you a tale about a good pal of mine when I operated at Motorola. The business moved the production of auto generators offshore, resulting in his transfer to my division. Although he had around two decades with the business, this was to be his last stop prior to being deposed the door.
He was designated to me as an Electronic devices Specialist, and also the very first project that I gave him was to lay out a small printed circuit (computer) board. It was a tiny circuit for a tester, so computer system drafting was not required. He could simply illustration it out on paper. After a number of days, he came back to me clarifying that he didn’t have the technological capability to set out a computer board.
An Electronics Professional that couldn’t lay out a basic pc board? Don’t all Electronics Technicians make little pastime circuits in your home? At the very least all the technicians I recognized did.
I clarified that he needed to draw lays out of the parts and also then use the schematic to attract lines between the parts links. After that, possibly reposition the parts if that would result in less going across paths. I also clarified something a lot extra profound, just how to handle the complexity of modern technology.
Many individuals, when they enter call with technology, consider themselves as well foolish to take care of it. Innovation is only for brilliants and geeks. Sometimes technology is as well intricate, yet it’s not due to the fact that people are silly, it’s since the technology is inadequately made.
For example, take software, like a graphics program, spread sheet or data source. Is the desired individual of the software program a computer developer, or an ordinary individual? These applications are intended for usage by an average individual. If an application is too complex for the ordinary person, the application is at fault – not the individual.
Why are most computers and software applications too intricate for the ordinary person? Due to the fact that they are made by developers that are under pressure to get the item out the door. Does the application have straightforward, simple help files? Software developers take into consideration assistance documents also lesser than application use.
– The lower line is, people are not dumb – computer systems as well as software application applications ARE too complicated.
In today’s world, where employees are required to use computers and innovation, exactly how can they manage the complexity? Back to the story concerning my buddy at Motorola.
After getting my instructions, he successfully completed the computer board format. I then introduced him to Computer system Automated Engineering (CAE). I showed him how to drag digital components from a collection, use the mouse to draw circuit courses, make the computer replicate the feature of the circuit, and after that make the computer system design a pc board for the circuit.
He was able to quickly understand complicated innovation due to the fact that he currently comprehended that he had not been foolish. Computer systems ARE facility. When he needed help, he researched the assistance data or asked a person for aid. At some point, his CAE skills ended up being well-known and also I lost him to another supervisor. “His last stop prior to being ousted the door?” I do not assume so. There’s no chance Motorola is mosting likely to let this important staff member get away.
Despite the fact that it’s the developers fault that computer systems and also software program are too complicated, that does not relieve you of all duty. You must make an effort. Like my pal at Motorola, you should study the help documents or ask someone for assistance when you require it. Not only should you study the aid documents, however you must additionally want to “attempt points”.
Lots of people are afraid that if they click the wrong point, the computer system will certainly explode and also they will be blamed for it. A correctly developed software program application stops the customer from making a fatal blunder, either by making it impossible, or by offering a caution message. An effectively designed application allows the customer “revoke” or reverse any action. One of the most effective ways to discover is to “attempt points”. If the computer impact ups since you made a mistake, you’re utilizing incorrectly developed software.
When you’re finding out exactly how to do a feature with a computer system, if you expect you may need to perform that very same function once more, keep in mind. Nobody will believe you’re stupid if you take notes. However if you keep asking over and also over again exactly how to do the exact same feature, they will certainly think you’re too dumb to remember.
When I operated at Motorola, I used a method called “strokes” to make symbols appear and also relocate around the computer system display like magic. Some people called me the “Digital God”. How did I get so good? I tried things. I fell short. I researched. I tried once more. I comprehended that technology IS complicated. So what?
In today’s society, being computer system illiterate is equal to being functionally illiterate. Make the effort to study the aid files and also to “attempt things”. Do not get dissuaded or blame yourself if you do not succeed on the very first shot. The computer will not blow up if you slip up. You can’t be successful at the workplace if you fail to embrace computers and technology.

Drivers

Drivers

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.

In plain English, a device driver is a program that allows various hardware to work on your system. The driver will allow your hardware to communicate with your operating system making the devices operable in the proper way. The user installs the driver and then the program allows the hardware to operate transparently without user input.

Computers and their operating systems cannot be expected to know how to control every device both now and in the future. To solve this problem, operating systems basically dictate how every type of device should be controlled. The device driver then translates these operating system mandated function cells into device specific calls. In theory, a new device which is controlled in a new manner should function correctly is a suitable driver is available. This new driver will insure that the device appears to operate as usual from the operating system’s point of view.

Depending on the specific computer architecture, drivers can be 8-bit, 16-bit, 32-bit and more recently 64-bit. This corresponds directly to the way the operating system is set up for which those drivers were developed. For example, in 16-bit Windows 3.11, most drivers were 16-bits which most drivers for 32-bit Windows XP are 32-bit.

New computers will often have device drivers already loaded into the system to make it easier for the user to just open the box and use their new system. But if you should happen to buy a separate component for your system such as a joystick, you will most likely need to install a device driver. The driver will come with the system, usually on a storage device like a CD-ROM. They will give you instructions on how to install the software and it is really quite easy if you follow the directions.

You cannot operate your computer system with separate components like a mouse without a device driver for that mouse. If you find that any part of your computer is not running properly, you may need to update your device drivers. Simply go to the website of the manufacturer of your hardware and they will usually have updated drivers available free for download.
