do the same for business. In April 1959, at an informal meeting at the University of Pennsylvania in Philadelphia, a small group of computer manufacturers, large users and academics asked the Department of Defense (DOD) to head the efforts (The Creation of COBOL,Brandel). The next month, the DOD called the first meeting of CODASYL, which consisted of eight computer manufacturers and a few large users. The DOD broke CODASYL into several committees, and by June, the nine member “short-range committee”
Introduction Computer systems can be found in varying environments, these are; at home, in businesses, computer gaming, networking and real-time situations. Computers systems can be classified into the following categories; microcomputers, minicomputers, mainframes and super computers. Different environments will have certain computer systems which are appropriate for that setting. Microcomputers can be categorised as personal computers (PC’s) and mobile computers. Mobile computers can be devices
In general, computers have been known to be a part of everyday life. What is not commonly known though is the abundant amount of different types of categories of computers out there and what is contained within those categories. By knowing some of these categories there is a better sense of knowledge on just how involved computers are in day to day lives. Three of the categories of computers is the functionality, size, and usage of computers. The functionality of computers is quite diverse. One example
Types of Computers Mainframes Mainframes Was the dominant form of computing before microcomputers. They are usually very expensive, powerful and operate specialist software Mainframes are typically used by large companies, public authorities and universities for their data handling tasks. These tasks are typically: File maintenance: This is perhaps the most common use of mainframes. Maintaining records is a huge task for institutions. Records can contain information on sales, credit card
single-user computers. They are used for common applications such as gaming, social networking, and internet research. Justify the performance, limitations Justify why this type is suitable to a particular environment Desktop: Desktop wasn’t designed to be portable. The expectation with desktop systems is that you will set the computer up in a permanent location. Most desktops offer more power, storage, and versatility for less cost than their portable brethren do. Laptop: A computer
manufactures many of the worlds most advanced technologies, ranging from computer systems and software to networking systems, storage devices and microelectronics. Indeed, IBM has various product lines and services a few of which are: the Personal Computer that was first created in 1981, AS/400 business system, RS/6000 family of workstations and server systems, S/390 enterprise server, groundbreaking ThinkPad notebook computer; the award-winning IBM Netfinity and finally, PC Servers. It is an important
receptive to the needs of our mobile workforce. The most critical tool involved in their success is the ability to reliably connect and access our company networks. These connections can be from employees using company issued laptops or personal computers used from home or on the road. For the most part we have addresses the needs of our sales force on a case by case basis but going forward we really need to ensure we have a defined policy to streamline remote access. To accomplish this there are
Isuzu Australia Limited (IAL) is an Australian based company that performs marketing and distributing for Isuzu trucks. The company was using a manual process to communicate and distribute the vehicles to multiple dealers. The manual process was inefficient, very costly and caused an increase of errors. Due to these multiple issues the Isuzu Australia Limited (IAL) moved its manual process to a more collaborative technology based process. Isuzu Australia Limited (IAL) realizing that the current
The History of Computers In order to fully understand the history of computers and computers in general, it is important to understand what it is exactly that lead up to the invention of the computer. After all, there was a time when the use of laptops, P.C.s, and other machines was unthinkable. Way back in the fourth century B.C., the abucus was an instrument used for counting in Babylonia. Many scholars believe that it likely started out as pebbles being moved over lines drawn in the dirt
An operating system is the program that manages all the application programs in a computer system. This also includes managing the input and output devices, and assigning system resources. Operating systems evolved as the solution to the problems that were evident in early computer systems, and coincide with the changing computer systems. Three cycles are clear in the evolution of computers, the mainframe computers, minicomputers and microcomputers, and each of these stages influenced the development
Computers and Society The decade of the 1980's saw an explosion in computer technology and computer usage that deeply changed society. Today computers are a part of everyday life, they are in their simplest form a digital watch or more complexly computers manage power grids, telephone networks, and the money of the world. Henry Grunwald, former US ambassador to Austria best describes the computer's functions, “It enables the mind to ask questions, find answers, stockpile knowledge, and devise plans

The micro-workstations are generally utilized & the quickest developing machines. These workstations are the least expensive
management systems require a mainframe to house the database management Depending on the size of the database, a large mainframe and terminal system could cost in the hundreds of thousands of dollars or millions of dollars. The mainframe required could have the extreme processing power and allotted memory compared to most personal computers. This makes the mainframe an expensive piece of equipment, and a large investment for most companies. The maintenance of the mainframe and database system could
user’s computer, putting it “in the cloud” where it can be plucked back out as needed – from any capable device such as a smart phone, computer or internet kiosk. Cloud computing is sort of like the first computers come full circle – in the early days of computing, users at terminals with no computing power to speak of made use of the number-crunching capabilities of mainframes in a shared fashion – in fact, the model of computer use was called “time-sharing.” As the personal computer grew in
this report is to study the current state of supercomputers and to briefly discuss predicted advancements in the field..A brief history about the supercomputer and its operation is initially outlined. Supercomputers are the supreme machines in the computer world. Supercomputers includes thousands of times the computing power of a desktop and cost several millions of dollars. They fill large halls, which are chilled to prevent their thousands of microprocessor cores from overheating. And they perform
2011). One technology that has been employed in the achievement of this endeavor is the use and creation of cloud computing. Cloud computing is a term that was coined as a metaphor representing the infrastructural network being used by myriads of computers and servers. This term has also been described differently based on its user application, infrastructure using it and supplying the services (Vaquero, Rodero-Merino, Caceres, & Lindner, 2009). This paper explores the definition of cloud computing
In a sense computers have been around for centuries. The abacus, a counting machine, was invented by the Chinese sometime between 500 and 400 BC. The numeral zero was first recognized and written by Hindu’s in 650 AD, without which written calculations would be impossible. In 1623 the great grandfather of the processor was born, the calculating clock. Wilhelm Schickard of Germany invented this adding, subtracting, multiplying, and dividing machine based on the principle of algorithms. For the next
Cloud Computing 1. Cloud Computing Defined Cloud computing is defined to be the use of computer programs and applications, to access information, storage, that is not stored locally on a computer’s hard drive, but rather over the Internet. There are five defining characteristics to cloud computing. Cloud computing allows users to have almost no interaction with the service provider. For example, when we use Google Drive, a web application similar to Microsoft Office, we can do so without ever
A console, also known as terminal is a basic computer connected to another computer, server or mainframe. Its function is to maintain the status of the network or computer. In some programs, console allows developers or advanced user to access the special features to issue command by pressing the tilde key when the program running. In Local Area Network(LAN), Ethernet is a physical and data link layer technology. used to connect more than one computer systems to form LAN that comes with protocols
Why the 1964 Operating System by IBM was so important to how computers are made today? Gary Tibbals Fountainhead College of Technology During a press release April 7, 1964 IBM Board Chairman Thomas J. Watson Jr. announced this was the most important product in the company’s history. (unknown, IBM, 1964). IBM knew that this was a special system due to how the system support was on a wide array of applications and it was the first operating system to require direct-access storage devices. (Hosch
