The
Waterfall model
is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete.
Which AV approach uses a variety of techniques to spot the characteristics of a virus?
Antivirus software
uses a variety of virus detection techniques. Originally, antivirus software depended on signature-based detection to flag malicious software. Antivirus programs depend on stored virus signatures — unique strings of data that are characteristic of known malware.
Which enterprise deployment model requires employees to choose from a selection of company owned and approved devices?
With the
CYOD model
, employees choose from a limited selection of approved, corporate-liable devices with the pre-configured security and control that IT needs to protect company data.
Which layer of the OSI model contains TCP protocol which is used for establishing connections and reliable data transport between devices?
The
transport layer
provides a total end-to-end solution for reliable communications. TCP/IP relies on the transport layer to effectively control communications between two hosts. When an IP communication session must begin or end, the transport layer is used to build this connection.
What type of radio frequency transmission are used by Bluetooth devices?
Instead of transmitting over one frequency within the 2.4 GHz band, Bluetooth radios use a
fast frequency-hopping spread spectrum (FHSS)
technique, allowing only synchronized receivers to access the transmitted data.
Which management system is used to support the creation and subsequent editing quizlet?
ANSWER:
Content management
is used to support the creation and subsequent editing and modification of digital content by multiple employees.
What are the four methods used in studying viruses?
These techniques are chemical/physical measures of virus quantification and they include
serologic assays, polymerase chain reaction (PCR), and hemagglutination assays (HA)
. Negative staining EM can also be used as a chemical/physical assay to detect and count virus particles.
What is antivirus software with examples?
It identifies and corrects any weaknesses found in the computer system. The main function of an antivirus is to scan, detect, prevent and remove any existential threat to the computer system. Examples:
Norton, McAfee and Kapersky
.
Which antivirus technique is used to detect virus?
There are four major methods of virus detection in use today:
scanning, integrity checking, interception, and heuristic detection
. Of these, scanning and interception are very common, with the other two only common in less widely-used anti-virus packages.
What type of deployment models allow the user to select the mobile device make and model?
What type of deployment model(s) allow users to select the mobile device make and model?
Bring Your Own Device (BYOD) and Choose Your Own Device (CYOD)
.
Which enterprise development model allows users to use their personal mobile devices for business purposes?
BYOD (bring your own device)
is undoubtedly the most well-known policy on this list, and the most popular deployment model for businesses. Under a BYOD policy, employees bring their personal devices to the office and use them for work-related tasks.
Which of the following must be used when setting up a DMZ?
To build a Demilitarized Zone Network, you need
a firewall with three network interfaces
: one for untrusted networks (Internet), one for the DMZ, and one for the internal network.
Which layer of the OSI model contains the TCP protocol which is used for?
This type of communication is known as “end-to-end.”
Transport layer
protocols at this level are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
Which layer of the OSI model contains TCP protocol?
The Internet Layer of the TCP/IP model aligns with the
Layer 3 (Network)
layer of the OSI model. This is where IP addresses and routing live. When data is transmitted from a node on one LAN to a node on a different LAN, the Internet Layer is used.
At which layer of the OSI model does the IP protocol function?
TCP and UDP port numbers work at Layer 4, while IP addresses work at
Layer 3
, the Network Layer.
Which frequency is used in Bluetooth?
Frequency. Bluetooth only does its work on a
2.4GHz
frequency, whereas many WiFI networks these days will run on both 2.4GHz and 5GHz frequencies.
What technology is used in Bluetooth?
Bluetooth operates in the range of 2400-2483.5 MHz. This is in the globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band. The radio technology used by Bluetooth is called
frequency-hopping spread spectrum
.
What is Bluetooth used for?
Bluetooth is a wireless technology that uses a radio frequency to
share data over a short distance, eliminating the need for wires
. You can use Bluetooth on your mobile device to share documents or to connect with other Bluetooth-enabled devices.
What isolates corporate applications from personal applications on a device?
Containerization
isolates corporate applications from personal applications on a device.
Which encryption protocol is used in the WPA2 standard?
Advanced Encryption Standard (AES
): AES is the encryption method used by WPA2.
What federated identity management FIM relies on token credentials answer choices?
What federated identity management (FIM) relies on token credentials?
Token credentials can be revoked at any time by the user without affecting other token credentials issued to other sites
.
What is the most common method used to identify viruses?
The most widely employed methods are
viral culture and antigen detection by FA staining or EIA
. Suitable specimens include nasopharyngeal aspirates, washings, or swabs; bronchial washings; and bronchoalveolar lavage fluid.
What instruments are used to study viruses?
Electron microscopy (EM)
has long been used in the discovery and description of viruses. Organisms smaller than bacteria have been known to exist since the late 19th century (11), but the first EM visualization of a virus came only after the electron microscope was developed.
What are the different laboratory techniques methods used in studying viruses?
A few of the most commonly used methods include: Virus neutralization (VN) • Hemagglutination inhibition (HI) • Enzyme linked immunosorbent assay (ELISA) • Indirect fluorescent antibody (IFA) • Complement fixation (CF) • Agar-gel immunodiffusion (AGID) • Agar-gel precipitin (AGP) • Latex agglutination (LA).
Is antivirus an application software?
Antivirus, backup software, file manager, disk compression tool all are
utility software
.
What are the four examples of antivirus?

What is computer software application?
In information technology, an application (app), application program or application software is
a computer program designed to help people perform an activity
. Depending on the activity for which it was designed, an application can manipulate text, numbers, audio, graphics, and a combination of these elements.
