Importance of Computers in Medical Sector

Computers have now become an inseparable part of our life. Be it school or colleges or offices or hospitals or home, there is hardly any place where you can’t see a computer. The importance of computers can’t be confided in words. Apart from making our work simpler, easier and faster, computers have actually helped humans in many life threatening situations. And this contribution can’t be put into words.

Especially in the field of medical and hospitals, we have seen so much advancement which was not possible had it not been computers for our help there. In this article we will discuss some major areas in medical sector where computers have helped us humans and made our lives simpler, easier and better.

1. Computerized Robotic Operations: Earlier days, if a patient is sick and needs treatment from the doctor, the doctors from the hospital have to be available in the hospital with that patient all the time. Performing diagnostics, operating a patient and post operation checkups required a doctor to be physically available near the patient. Now it’s not the case. With the advancements of computers, hospitals have introduced cutting edge technologies and treatments methods using which a doctor can perform the diagnosis and checkups thousands of miles away from the patient.

Even operations are performed remotely with the help of robotic arm. The introduction of robotic operations has made lives of so many needy patients easier. If certain services are not available locally, the patient now needs not to travel hundreds of miles to go to a better hospital. The hospital and its services will come directly to him/her. The doctor can perform the remote operation with the help of the robotic arm placed near the patient and checking all the vital body factors on the digital display in front of him/her. It’s literally like doctor is performing the operation in person. The introduction of robotic operations has made the operation and treatment of the needy patients much faster, easier and cheaper at the same time.

2. Computerized Internal Diagnosis: There are often scenarios where the doctor needs to perform the internal diagnosis of the patient to get the clear picture and state of the disease. Certain tumors and cancer may seem neutralized from outside but from inside the situation can be completely opposite and this can’t be found out until unless a proper internal diagnosis of the infected body part is performed. Even performing CT Scans, X-Rays and other scans can’t give a proper state of the disease and can delay the treatment at the same time.

The introduction of computerized internal diagnosis has made the job so much easier, faster and effective. While employing the computerized internal diagnosis, most of the times a computerized tiny robot with a camera head is inserted in the body of the patient. The tiny robot makes its way through the infected part of the body providing real-time images of the internal parts at the same time. The doctors can literally see each …

What Does Software Engineering Involve?

The first point that has to be made about software engineering has to do with its scope of activities. Software engineering is the management of the entire process of development of computer systems to solve problems.

As software systems have grown more sophisticated and complex, software developers have sought new methods for their development. Software engineering is a response to that need. Software engineering is still rapidly changing and maturing.

Typically, when someone is told to write a program, someone else has told him or her what the program is to do and why; the programmer is concerned only with how to write it. As software engineers, however, we will be the ones concerned with the what and why. Software engineering includes the whole range of activities having to do with problem solving – from helping the client define the problem or opportunity, to evaluating the client’s satisfaction with the solution.

Developing a software system may require writing a whole collection of programs to tell machines what to do, writing procedures to tell people what to do, and providing training so that people understand how to do it. We may need to convert data from an old system so it can be run by a new system, hire people and acquire machines to run the programs, and obtain space in which the machines and people can do their work. What we are building is a system of many parts working together. Such an endeavor requires patience and flexibility. We will have to fix the system when it does not do what we expected, or the client may ask us to change the system because he or she wants it do something else not previously intended.

Programming may be no more than 20 per cent of the total scope of software engineering, and the fraction of effort involved with programming can be expected to drop as improved methods are used for developing software systems. As time goes on, more of our effort will go into managing the overall process and less into programming.…

Introduction to Computer Monitors

A monitor is the primary output device for a computer. The two main types of monitors currently in use are Liquid Crystal Display (LCD) also known as flat panel display, and the Cathode Ray Tube (CRT), which is an older technology. Each has advantages and disadvantages.

Most older monitors today use cathode ray tube technology, which was first developed for use in television sets. The cathode is a negatively charged electrode that shoots a beam of electrons towards a positively charged electrode, known as an anode. The cathode ray tube is a vacuum tube containing one or more electron guns (cathodes) at one end, which fire a stream of electrons at a screen at the other end. The inside of the screen is covered with a matrix of dots composed of phosphorescent material, known as phosphors. When the phosphors are struck by electrons, they emit light. Phosphors are organized in groups of three, known as a pixel. Each pixel contains a dot that emits one of the three basic colors: red, green, and blue. Magnetic coils in the tube control the direction of the electron stream, and a control grid determines the color combination on the screen. The electron stream starts at the top of the screen moving from left to right, line by line to build an image.

An LCD monitor on the other hand uses a layer of liquid crystal material sandwiched between two grids of electrodes, one arranged in columns, the other in rows. These grids in turn are enclosed by a layer of polarizing material made out of plastic or glass. These polarizing layers are aligned so as to prevent light from passing through when the electrodes are not activated.

To generate an image, light is passed through the first polarized layer. As the light passes through liquid crystal material, the polarity is changed to allow it to pass through the second polarized layer. This is done by manipulating the electrode grids. The pixels are formed by liquid crystal cells that change the direction of light passing through them in response to an electrode grid.

LCD monitors today most commonly used what is known as thin film transistor technology (TFT), in which a transistor is placed at each intersection of the electrode grids, enhancing the signal and therefore the picture quality. This is also known as active matrix display, as opposed to the older technology known as passive matrix display.

There are many features to be considered when choosing a monitor. Some of the more important ones are: screen size, resolution, dot pitch, refresh rate, and response time. Screen size refers to the diagonal length of the screen surface. Resolution refers to the number of pixels that the monitor can display, for example 640 x 480, which indicates 640 pixels horizontally by 480 pixels vertically. The more pixels displayed, the sharper the image. Dot pitch is the distance between dots, expressed in millimeters, such as.25mm, with the smaller the number the better the image. The refresh …

What is the Difference Between Compiling and Debugging?

Debugging:-Computer programmers, like everybody else, are not perfect. This means the programs they write sometimes have small errors, called “bugs,” in them. These bugs can be minor, such as not recognizing user input, or more serious, such as a memory leak that crashes the program. Before releasing their software to the public, programmers “debug” their programs, eliminating as many errors as possible. This debugging process often takes a long time, as fixing some errors may introduce others.

Compiling:-When programmers create software programs, they first write the program in source code, which is written in a specific programming language, such as C or Java. These source code files are saved in a text-based, human-readable format, which can be opened and edited by programmers. However, the source code cannot be run directly by the computer. In order for the code to be understood by the computer’s CPU, it must be compiled into an executable program.

Most software development programs include a compiler, which compiles source code files into machine code. This code, sometimes referred to as object code, can be executed directly by the computer’s processor. Therefore, the resulting application is often referred to as an executable file. Windows executable files have a .EXE file extension, while Mac OS X programs have .APP extension, which is often hidden.

So the conclusion is a compiled program may have errors or bugs but not a successfully debugged program cannot have any.

So for a perfect program you need to debug and compile a program…

Methods of Computer Networking

Computer networks can be classified into three broad categories.

Local area network (LAN)

A local area network remains confined in a relatively small space. It is useful in providing services to a small number of people. Networks in small offices, and homes are some examples of LAN.

Small office and Home networks are also peer-to-peer networks where minimum resource is used and each client shares their resources with other workstations in the network.

Another LAN is a client-server network where every client remains connected to the server and each other. Servers in client-server networks are of different capacities. There are two types of client-server networks:

  1. Single-service servers performing single task, say, as a file server; and
  2. Print server performing multiple tasks, say, as file server, print server, conducting calculations and providing information to client on basis of result of the calculations.

Ethernet cables, Wireless networks, or other types of wires such as power lines or phone lines may be used to connect computers in LAN.

Wide area network (WAN)

Wide variety of resources is deployed in WAN. These networks spans not only over large domestic area but also internationally. The connectivity of computers in branch offices of a corporate organization is an example of WAN. But the greatest WAN on the earth is Internet, a network of numerous smaller networks. Besides Internet, another enormous WAN is Public Switched Telephone Network which is converging fast with the Internet technologies.

Wireless networks (WLAN, WWAN)

A wireless network is based on data transmission over sets of radio transceivers. Basically it is same as a LAN or a WAN. Only difference is that there are no wires between hosts (clients) and servers. These types of networks are useful for locations where setting up wired networks is either too costly or inconvenient. It uses IEEE media access protocols for LANs. For connecting nodes over larger distance either satellite communications of various types or cellular radio or wireless local loop are in vogue. But speed and quality of data transmission varies largely depending on the means of communication used.…

How to Program a Symbol LS2208 Barcode Scanner

The Symbol LS2208 scanner is a very popular, lightweight, ergonomically designed barcode scanner used in conjunction with many Point of Sale (POS) software.  However, prior to using the scanner with POS software there may be some very simple programming steps that will need to be take to get the scanner ready for operation.

One of the first steps to programming a Symbol Scanner is to program the type of interface that you will be using with the scanner.  If you are using USB or Keyboard Wedge interfaces, you don’t need to worry about programming the scanner as the scanners come pre-programmed to use these interfaces.

If you are going to be using the RS-232 or the IBM 46XX interfaces there is a very simple step you must follow to program the Scanner.  In the LS2208 Quick Start Guide, under STEP 3 you will have to scan the appropriate barcode for either an OPOS/JPOS or a Standard RS-232 interface.  Simply by pointing the scanner at the appropriate barcode and scanning it, you will be programming the scanner to use that interface.  The Quick Start Guide also has barcodes you can scan for the PORT 5B or PORT 9B – IBM 46XX interfaces or to switch back to USB or Keyboard Wedge mode.

Once you have the interface programmed, the next thing you will need to program is the enter key, carriage return/line feed function.  This function programs the scanner to append a carriage return/line feed character to be sent to the computer at the end of each barcode that is scanned.  This will eliminate the need for your cashiers to have to hit enter after scanning a barcode in their POS system.

To program the enter key, carriage return/line feed functionality into the scanner all you need to do is simply scan the three barcodes found in the Quick Start Guide.  There is also the option of appending a tab key to the end of a barcode scan in the manual as well, and is performed the exact same way as programming the enter key.…

Mouse – One of the Most Important Computer Components

A computer cannot function in the way it does without its components. The different computer components like the motherboard, CPU, RAM, HDD, PSU, visual card make what computers really are. Apart from these basic components which are universal and present in every computer there are many additional components like the printer, scanner which do not play any role in the functioning of the computer. However, apart from all of these components there are three other peripheral components like keyboard, monitor and mouse which help in the running of the computer.

Why Is Mouse So Important?

Like all basic computer components mouse too plays an important role in the functioning of the computer. Without a mouse a person cannot afford to input data in to a computer. Though you can definitely use a computer without the help of a mouse but a mouse can largely reduce the time and effort of a person when using the computer. So a mouse can definitely make your job of working with computers easy. When buying a mouse for your computer you can choose from a variety of 3 types of mice- the ball, optical ball and the laser.

Know About the Three Types of Mice

The variety called ball was first created and has a rubber or metal ball inside the body of the mouse which is mechanical in nature. Though the optical variety is quiet similar to the ball mouse the former is uses optical light to detect the movement of the ball within the mouse. The optical ball mouse needs a mouse pad for proper functioning. The laser light works with the help of a laser light that detects the movements. This variety does not require a mouse pad for its functioning and is preferred over traditional varieties of mice as they can respond more quickly to actions.…
