(Unit 3) Hardware and Software WRAP-UP!

What hardware trend may affect the engineering department?

Cloud computing x3-D printing Monitors Correct! 3-D printing is a hardware trend, and you are certain that the engineering department will be submitting a hardware requisition for one in the near future.

True or False. DOS is an advanced operating system that has been used at the airport.

False Correct! DOS is an older operating system from the 1980s that has been replaced with Microsoft Windows at the airport. (scenario)

True or False. Airports use only modern hardware technology.

False Correct! Minicomputers, which are a computer system predating PCs, are still used at many airports. Minicomputers were developed in the 1960s in place of some mainframe or mid-size computers.

True or False. One of the goals in the airport scenario is to eliminate the need for PCs.

False Correct! PCs would still be required to house central processing units (CPUs) to carry out specific instructions and activities, BUT the HARDWARE AND SOFTWARE would be more reasonable in a CLOUD-COMPUTING system.

Web browsers such as:

Google Chrome and Firefox (provide access to web pages on the Internet.)

What hardware is still in use that was developed during the early stage of information technology infrastructure and used as small servers operating business and scientific applications?

MINICOMPUTERS. CORRECT! Minicomputers predate PCs and are still used at the airport. They are more powerful than microcomputers, but less powerful than a mainframe.

What programming language was essential for the development and maintenance of legacy computer systems used at the airport?

Microsoft Windows x COBOL Java (scenario) COBOL and SQL were essential for the development and maintenance of legacy computer programs, but standardizing on one operating system eliminated the need to employ programmers familiar with those programming languages.

Software can be in the form of applications used in the operating systems, like:

Microsoft Word or Adobe Acrobat

What is one of the benefits of using open-source software at the airport?

Reduced storage space Reduced processing delays xReduced costs Correct! Open-source software reduces costs because, unlike proprietary software, there are no licensing fees.

What existing data OUTPUT hardware can be partially replaced by the smartphone?

Scanners xPrinters Monitors Correct! Printers are an output device, but instead of printing boarding passes, passengers can use smartphones to show boarding pass.

What two factors related to software will help determine future computer hardware purchase requirements?

Speed and memory Correct! In planning for a computer system purchase, you will need to determine current and anticipated software needs, which will help you decide the speed and memory requirements for future computers.

Microcomputers are from 1970s and 1980s and pretty much the same as personal computers in capability. Microcomputers typically have all their hardware in one place, embedded in a case and are more portable than PCs.

TRUE

A company should select software and hardware based on need and evaluated in a way that provides the best efficiency and cost effectiveness for the business.

TRUE. Some functional units or departments may require different hardware or software because the work they do on a computer is different than what other departments or users do.

tertiary storage

This is a third level of mass storage provided by a robotic arm that mounts or dismounts offline storage depending on operating system needs.

Software can be in the form of operating systems, such as:

Windows 10 or OS X

One of the MAJOR SOFTWARE ISSUES faced by modern organizations is the COST OF PURCHASING AND RENEWING software licenses. .What option is being investigated to reduce software costs?

XOpen source Proprietary Freeware Corrrect! Some of the proprietary software licenses are nearing expiration so businesses are investigating open-source software alternatives to further reduce costs.

Some software is stored remotely on a server and accessed by a client in a client-server environment, which is referred to as:

cloud storage or cloud-based (cloud-hosted) applications.

If cloud computing were used to reduce storage costs, then cloud computing would function as _________ storage

secondary. The CLOUD COMPUTING would serve as SECONDARY STORAGE because primary storage is located in the computer for quick access.

What will assist the airport with analyzing and responding to trends?

smartphones x Analytic applications behavioral targeting Correct! Analytic applications are a type of application that are used to measure and improve business performance.

At the MICRO level, the computer is comprised of different types of hardware, such as

the motherboard, RAM, or memory (volatile), input devices such as a mouse or keyboard, a monitor as a display device, and storage devices, such as hard drives
