IT Vocab 8 Flashcards
A family on standards that deal mostly with how data is transferred between hosts in a local area network (LAN)
IEEE 802 Standards
An application architecture model with three separate tiers where an application presents the user interface on a client workstation, data is processed on an application server, and information is retrieved from a database management system on a database server
Three tier
A protocol used to receive email; it is deleted from a server after it is downloaded to a client
Post Office Protocol 3 (POP3)
A method of delivering applications by installing them in the local network
Network Hosting
A method of delivering applications by hosting them in the cloud
Cloud Hosting
Security protocols that govern how data in a wireless network is secured by encryption. Examples of these protocols are Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and WPA2
IEEE 802.11 Encryption Protocols
A term associated with cloud hosting; providing users with the application they need to do their day-to-day work through the cloud
Software as a Service (SaaS)
The traditional method for delivering applications by installing them on individual desktop computer systems
Local Installation
A characteristic of 802.11 protocols that require protocols to transfer data at a specific number of bits per second
Speed
A software license, often called a volume license or a site license, that allows the customer to install the software without restriction using the same activation code, typically until a maximum cap is reached
Enterprise License
A software license given to home and small business customers that allows them to install the software on a limited number of systems
Personal License
An application architecture model where programs run as standalone applications on a single computer
One tier
an application architecture model with two separate tiers (a client and a server) where applications store and retrieve data from a central repository
Two tier
A person that maintains and expands a company’s network. They install and configure network media, create and manage user accounts, implement firewalls and other network security, manage an organization’s mail system, configure network printers, and maintain Internet connectivity
Network Administrator
A feature of radio waves where the signal becomes weaker as the wave travels further from its point of origin. 802.11 standards require that signals are strong enough to cover a specific distance
Attenuation
A person that works closely with network administrators to ensure uninterrupted access to the company network. They troubleshoot problems reported to a company’s IT help desk and assist users in resolving network connection problems, such as replacing defective network cables and modifying Wi-Fi settings
Network Technician
Software that can be downloaded, installed, and used without paying a licensing fee. The source code can also be downloaded, modified, and compiled and given to others as long as it is not resold for profit
Open Source Software
A person that develops and implements an organization’s communication network, including the hardware and software components needed for both physical and wireless connections
Network Architect
A characteristic of a radio signal that carries digital information in a wireless network. 802.11 standards specify two frequencies, 2.4 GHz and 5 GHz
Frequency
A family of standards under the 802 standards that deal with how data is transferred between hosts in a wireless network. Popular 802.11 standards are 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac
IEEE 802.11 Standards
A concern with using enterprise software in a network with multiple computer platforms and operating systems
Platform Compatibility
A feature of the Windows operating system that keeps the operating system up to date
Windows update
Software that isn’t owned but requires the purchase of a license to use the software
Proprietary software
An application architecture model where application developers add as many tiers as they need to create the most efficient services and processes on a network
n-Tier
A protocol used to receive email; is saved on a server even after it is downloaded to a client
Internet Message Access Protocol (IMAP)
Sometimes called SaaS or on-demand software, software that requires a monthly or annual fee to use the software and receive regular updates
Software Subscription
