Chapter 2: Application Software Application software: performs tasks like creating a budget for accounting or supply chain, creating a resume, making a professional presentation for a business proposal o A user’s choice – human intervention Ex: Email, word processors, spreadsheets, databases, presentation software, and project management software Word Processing Software o Word processor: application software used to create, compose, edit, format and print documents Microsoft Word Adobe Acrobat or Corel WordPerfect o Businesses use it to create memos, legal documents, or any other document application Microsoft Word: distinguished by “.doc” or “docx.” o Allows images, spellcheck, grammar checking, and other features Adobe Acrobat o Allows user to create, edit, format, and print portable document format files (PDF files) o Freeware product for viewing, printing, and annotating PDFs and resides on virtually every platform o Can be digitally signed Corel Word Perfect o Developed at BYU for Data General Minicomputers Spreadsheet Software o Spreadsheet: electronic grid of columns and rows used to create, model, and manipulate numerical and financial information o Columns = letter o Rows = numbers o If columns and rows intersect, they form a cell Database Software o Database software (DBMS) – used to create a collection of related files called tables Consists of records (rows) of data separated by fields (columns) that can be queried to produce populations of information Presentation Software o Presentation software: used to present information in a slideshow format o Businesses rely on presentation software to communicate and collaborate in strategic and tactical meetings o Allows user to further enhance a presentation Specific-use Application Software o Allows user to view items via Internet o Network Software – allows computers to communicate with each other Browser Software o A browser or web browser – user interface software that allows the user to display web pages found on the World Wide Web o Display hyperlinks that are clickable navigation elements that let the user navigate from one web page to another Microsoft Internet Explorer Google Chrome Mozilla Firefox Apple’s Safari Networks o Computer Networks: two or more computers connected together for resource sharing and communication o Resources refer to Computer files Folders Software Printers, scanner, webcams, etc. Choosing and Buying A car o You may not know how it works o It starts every time o It sounds good o No immediate problems o Its clean and looks good Choosing a technology and buying it o You may not know how it works o It seems to work every time The System Unit o Main body of the computer o Contains the motherboard o Contains assorted computer components Power supply Cooling fan Disk drives Primary memory Secondary memory Expansion cards/slots Etc. The Motherboard o Sometimes called a system board or logic board Essentially a circuit board Printed Circuit Board (PCB) Replace loose wiring Reduced size Made of non-conductive plastic o The motherboard is analogous to land that contains buildings, roads, and infrastructure. o Imagine a large piece of land with an enormous distribution center in the middle, with roads from all points of the compass o The distribution center is the microprocessor on the motherboard The Microprocessor o The brains of the computer o Central processing unit (CPU) o Measured in clock rate Interprets program instructions Process data Gives the computer the ability to be programmed o The microprocessor is the distribution center in land o It uses different algorithms to process hits 8 hits in a byte 1,024 bytes in a kilobyte 1,024 kilobyte in a megabyte 1,024 megabytes in a gigabyte 1,024 gigabytes in a terabyte 1,024 terabytes in a petabyte The Bus Lines o Pathways that transfer data and power o Controlled by software to connect to devices o Measured in width Binary Systems o Made up of 2 parts o In the case of a computer, a ‘1’ or a ‘0’ which are bits o 8 bites in a byte Most microcomputers use ASCII Power Supply Unit (PSU) o Converts Alternating Current (AC) to Direct Current (DC) o Some PSU can sense a wide range of AC System Units o Store Memory o Retain memory o Process memory o Memory holds information that is electronically stored on a computer like spreadsheets, images, and data 2 types of memories Primary Memory (volatile) o What the user is currently working on Secondary Memory (non-volatile) o Where the information is stored Memory is stored as 1 or 0 and translated for human with computer screens, keyboards, microphones, etc. Primary Storage – Random Access Memory (RAM) o Volatile o In the form of RAM Chipsets mounted on motherboard o Allows data to be accessed in any order o No physical movement Secondary Storage – hard-drive, cloud drive, etc. o Non-volatile o Spinning device (hard drive or optical disc) o Does not require electricity o Like a metal filing cabinet where files are stored, can be taken out and placed on a desk [ram] for use. Once making changes is done, it’s returned to the filing cabinet, which is the secondary storage. Input and Output Device o Translates Machine Code o Turns ‘1s’ and ‘0s’ in output o Turns input into ‘1s’ and ‘0s.’ o Input data and information that enters a computer and is translated into machine code like through a keyboard or microphone o Output is data and information that exits a computer system and is translated for human comprehension, like computer monitor or speaker.
