Information Systems Management- Module 3- Hardware and Software- Computer System Uses
What is the difference between a dumb terminal and a client?
A dumb terminal is for input and output, while a client can also process instructions. A client has a CPU allowing it to process instructions, while a dumb terminal is limited in power and therefore cannot process instructions.
Characteristics of laptops and desktops:
A laptop is used for mobile telecommuting staff, smaller, and is usually powered by a battery, while a desktop is used by office staff, bulkier, and requires AC current from an electrical outlet.
What is the difference between a dual core and quad core chip?
A quad core offers more power, allowing more multitasking capabilities.
Two types of system software:
Application software- operating systems are system software and essential component in every computer to help manage the hardware and software resources. Utility software- system software that helps analyze, configure, optimize, and maintain a computer.
A popular operating system that enables cloud computing by storing programs on the internet and accessing them through the Internet browser
Chrome OS works with web applications and installed applications enabling cloud computing by storing programs on the internet to be accessed through a browser.
What popular operating system enables cloud computing by storing programs on the internet and accessing them through an internet browser?
Chrome. Chrome OS works with web applications and installed applications enabling cloud computing by storing programs on the Internet to be accessed through a browser.
Open Source Software
Created and updated by multiple programmers and available at no cost, and for this reason contains fewer defects.
What is the first step in the decision process when evaluating technology purchases for business?
Determining how the technology will be used, including requirements.
OS X
Free OS and re-creation of UNIX, but more popular than UNIX for workstations. Widely used operating system for multi-users. Millions of programmers participate in its development.
How have wireless handheld computer devices dramatically increased productivity?
It allows communication and access to information without a landline connection.
Determining how the computer system will be used, including requirements:
Mobility (laptop or tablet) Operating system (Microsoft Windows, Apple OS X, or Linux) Application software (Office productivity suites and specialized software) Screen size or number of screens Performance Analyzing the available options and their respective costs and benefits Selecting the best option and gaining approval Evaluating the choice after the fact
Linux
Primarily used on servers but does not support the range of applications that most users need on a desktop. Open-source operating system that works on many devices and is similar to many of the other graphical user interfaces. Found in cell phones, smartphones, and consumer electronics, including PCs.
Proprietary Software
Sold for a fee and is often restricted in the number of computers on which it can be installed. Ex. Microsoft Office
The most common client-level operating system installed on PC's is Microsoft Windows?
True. Approximately 90 percent of PCs use a version of Microsoft Windows as the operating system.
Windows
Used on Apple computers and runs on a UNIX engine, but with an easy to use graphical interface. The market leader for workstations and servers. It has its own internal software and graphical user interface that is easy to use.
Programming Language
Used to create a computer program that gives instructions to the computer.
What systems work better for engineers?
Workstations. Engineers need fast, powerful computers capable of running engineering applications.
Object oriented programming
a blueprint of an object is called a class. A class is the blueprint for an object. Similar to building blueprint, a class is a template for an object.
2-in-1 computer system
a laptop that can be used as a tablet
Hyper Text Markup Language (HTML)
a markup language used to create web pages.
Structured Language Query (SQL)
a programming language designed for managing data in a relational database management system. Communicates with the database.
Horizontal
applications are more popular and general purpose, such as word processing software, spreadsheets, and presentation software.
Virtualization
assigning part of a computer system to run different operating systems. The act of virtualization creates a virtual environment in a host computer to save space, reduce costs, and provide a safe test environment.
Application Suite
bundle of application programs with related features and functions. Ex. Microsoft Office, accounting software
Algorithm
is a set of operations to be performed. Perform data processing and calculation in a computer. Form of logic that enables the computer to produce an output from a given input.
The purpose of operating system:
is to manage the activities of the computer.
JAVA
multipurpose programming language used to create computer applications, play games, and communicate with friends.
Wireless Computer Devices have enabled:
point of sale payment and remote collaboration.
Simulation Software
simulates actual systems and is typically used for training, entertainment, or research.
Application
software is a set of one or more programs that allows a computer user to perform a group of coordinated activities, functions, and tasks. Includes programs such as database, word processing, presentation, web browsers, and spreadsheets.
