This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

At present, computer systems are including into hospitals and medical clinics in the world. It's use for patient treatments and helps to handle the hospital information and data better. Today, computer systems include to the hospitals to develop their performance

Application of computer system in hospital

The imported of computer system in hospital, to do well their works. The disadvantage is that a full-fledged installation of all the computerized systems in hospitals is a lengthy and costly process. However some hospitals are used basis computer system to do their works.

Computer system use in hospital for

Handling Medical Data.

Scanning and Imaging.

Examination and Monitoring.

Handling medical data.

Every day hospitals and clinics which are attached to it churn out enormous volumes of data.

There are,

Patients.

Ailments.

Prescriptions.

Medications.

Medical billing details.

Such medical reports are recorded into medical billing software at present. Such big data base are recorded into electronic medical record (EMD) and electronic health record (EHR). These databases are operated by a set of computers and servers, and it gives handy medical alert and emergencies. The concept of EHR is a bit broader than the EMR, as the database is accessible from different clinics and hospitals. Thus, a patient's medical history can be retrieved from any hospital by medical practitioners.

Scanning and imaging.

These specification components can be scanned human body. This component can be as normal blood test or it can be complex CT scan. This process is often referred to as a medical imagery. In order to increase the precision of such procedures, computers have been adopted and integrated into the testing equipment. The Ultrasound and the MRI are the best examples where computers have been adopted, in order to make the process faster and precise. Such medical tests and tools have become more advanced as a result of the use of computers.

Examination and Monitoring.

Many computer systems are used in hospitals for the development of medical monitoring. Computer system helps humans to properly monitor their own health. Doctors and sergeants also use modern computer aided equipment to treat their patients. These systems and processes include,

Bones scan procedure.

Prenatal ultra sound imaging.

Blood glucose monitor.

Advanced endoscopy which is used during surgery and blood pressure monitors.

Basically these medical tests and tools provide easy to do their work. Mainly laboratory equipment and heart rate monitors are computerize in many hospitals.

Advantages of computer in hospitals.

Uses of Computers in an Airline Industry.

Air lines Industries have many different systems, as schedule their passenger information and ensure to flying safely. All of these computer systems relay want in air line sector. Computers are included in everything from passenger's travel arrangement, function of an airport and the airplanes that are flying into it.

Description of Some Ways, Computer Applications are Applied in the Airline Industry Airline Industry Structure

Passenger service.

Airport service.

Airline flight and prices.

Air traffic.

Plane mechanics.

Passenger service.

When you book flight, your reservation information is processed and stored by the airline's computer system. When you register online, your information's are directly stored with company. When your book over the phone. Then customer care centers are collecting your information's and they will entree your information in to the system. As computer base reservation system, you can easily modify your travel arrangement at any airport, and even to use multiple airline companies over the course of a single trip.

Airport services.

Airport service used rely heavily computer systems. There are security screening machines such as x-rays. It's used for security. And it's not like personal computers. Airports are using great computer system for their security. Furthermore, computers are necessary for the use of pre-screening measures such as the current U.S. counter-terrorism efforts.

Air traffic.

Computers are very important to control air traffics. And all air traffics are controlled by air traffics controller services. While the communication between air traffic controllers and pilots occurs through radio, through this system communication can be done by radar and weather data, it is a basis operating process. Computers allow air traffic controllers to locate the plane which is in the air. Then the pilot can identify the location of the plane on air and land safely.

Plane Mechanics

An airplane depended on computer system. Computer systems are heddle number of function in airplane. The autopilot, which many modern airplanes are prepared with, always employs a computer. As computer system make easy the pilot of many in flight task, And the plan to process negotiation data and flight control system. Computerized "fly-by-wire" technology, which many airplanes have, transmits pilot or autopilot signals to a computer. This allows planes to respond to subtle atmospheric variables and make other adjustments easily. Normally, some airplanes have wing flaps. That can be controlled by a computer. At last, computers are central to the efficient communication and recording of an airplane's flight data.

Such data very imported to controlled air traffics.

Computer system in bank

Computers are used in banks for several reasons. Computer system helps in banks to do their process well. Computer systems are using store data for effectively. They help process other customer information as well. Without the computer the banking process can be very hard. Then they can't hold good customer services in the bank sector. That's why, computer system are very important in the bank sector. Computers help the bank to save time and money, and can be used as a help to generate profits.

The sectors of E-banking.

Customer Information.

Products

Reports and Profits

Transactions and Goals

Credit Applications

Delinquency

Miscellaneous

Customer information.

Basically, Bank use computers to store customer information. They are name, address, and phone number, date of birth, Social Security number and place of employment. This information is used to keep in touch their customers and identify any changes of their policy. And customer's information also stored in computers. Mainly, store customers account number, because, it helps bank employees to do their work well.

Products.

A customer' products and services are also stored in computers. Bank manager will call the customers periodically and offer them products or services. This system helps to know which products and services a customer already has before new products are offered. It would be difficult to keep track of this information, without the use of computers.

Reports and Profits

In banks, with the use of a computer the administration can analyze aging reports and track the customers who have had dishonored cheques. This report can be used to call the customers and offer them the product called Bank Overdraft Protection, which prevents a customer from overdrafting their account. These computers help the bank administration to earn income by targeting certain customers for sales activity.

Transactions and Goals

All transactions of the day are recorded in these computers. All deposits, withdrawals, cash cheques, and every other transactions are recorded when a teller or a bank employee feeds it into the system. After comparing all the information, the branch manager will print the report at the end of the day to see whether the branch had reached its goals for the day.

Credit Applications

Banks are using computer for new loan applications and credit card applications. The computer systems are used into open to the new accounts, check for saving and certificate of deposit accounts.

Delinquency

Computers can control induviguaily reports for customers who are 30-, 60- and 90-days delinquent on their accounts. Also, computer can identify individually from costumer's records, who are 30-, 60- and 90-days delinquent on their accounts. Then bank reprentives can identify easily, who are the delinquency customers. And after then, they can be collated from customers contact information easily. Then computer systems are helps to under control delinquency.

Miscellaneous

Computer systems are helps to keep their record, all of communications from bank employees and customs activities. And computers are used for safety deposit box. Then they can keep record that. Who are the customs in safety deposit box?

Computer inputs.
