Answer:
b. Random Access Memory
Explanation:
In computers, there are 2 types of memory: Volatile and Non-volatile memory. The first one is also known as RAM (Random Access Memory) and it is used by the PC when it needs to store data and programs temporarily and have immediate access when they are used. Notice that this memory is deleted when the computer is shut down.
On the oher hand, the Non-volatile memory (also known as ROM- Read Only Memory) is used to store data in a more permanently way so that crucial Operating System data files as well as all the programs installed are not deleted when the computer is shut down.
Due to the above, the answer is Random Access Memory (RAM).

A user has a network device that streams media to the LAN. The device is visible on the network. All PCs on the LAN can ping the device. All firewalls are turned off. The streaming device appears to function properly, but the media will not stream as requested. Which of the following TCP/IP technologies is not implemented properly?A. MulticastB. BroadcastsC. UnicastD. Anycast
Answer: A. Multicast
Explanation:
Here we are given a situation where it is necessary for the device to stream media to all the PCs connected across the LAN. But as the they are unable to stream the media then it is a problem in the multicast TCP/Ip technology.
Multicasting enables to transfer information or messages from one to many or many to many. Here as a single device is responsible for streaming the content to other PCs across the LAN, therefore it is necessary that multicast has been properly implemented.
Option B is incorrect as it is not a scenario of broadcast as in broadcasting all the receivers must get the streaming however here if a PC does not want to receive the media stream it cannot receive for which multicasting is required.
Option C is incorrect as here we are not talking of one to one communication.
Option D is incorrect as here we cannot have more than one route to send the media content except the LAN.

Most of the enterprises and organizations collects huge amount of data through the use of MIS. These data can be based on any aspect of the business. But the collection of such large sets of data is useless until and unless there is a business intelligence associated with it. the work of business intelligence is to use software tools for analysis of the collected data so that it could be useful for enterprise or company to look for patterns and trends in the market.
The outcome of such business intelligence is very helpful particularly to managers, executives for taking particular decisions in the greater interest of the company.
So we can say, business intelligence is an approach to boundary spanning that results from using sophisticated software to search through large amounts of internal and external data to spot patterns, trends, and relationships that might be significant.
What component of enterprise level structured cabling serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling?
Answer: Entrance facility
Explanation: Entrance facility is the service of the telecommunication field that provide entrance in the building in the situation of private network cabling and public network cabling.
This cabling connects the outdoor cables to the backbone cabling of building.The points that can be cabled at the entrance point like wall of the building, entrance room, floor of the building etc.
Final answer:
The Entrance Facility (EF) is the component in enterprise-level structured cabling where external communication lines enter a building and connect to the backbone cabling. It handles the transition from outdoor to indoor cabling and adheres to standards for structured cabling systems.
Explanation:
The component of enterprise-level structured cabling that serves as the location where an incoming network interface enters a building and connects with the building's backbone cabling is known as the Entrance Facility (EF). This crucial segment is where external communication lines from service providers, which can include telephone lines and data services, meet the internal cabling infrastructure. Within the EF, the transition from outdoor cabling to indoor cabling takes place, which may involve connecting to different types of media such as copper, fiber optic, or coaxial cables.
The structured cabling system typically adheres to a set of standards like ANSI/TIA-568 that outline how to wire an office or building for data or voice communications. These standards ensure connectivity for various structures and devices used for communications, including computers, servers, and telecommunication devices. The backbone cabling then distributes these connections throughout the building to different floors or sections via intermediate and horizontal distribution frames.
Identify the false statement.
a. When you perform arithmetic operations with operands of unlike types, you must make an explicit conversion to a unifying type.
b. You can explicitly override the unifying type imposed by Java by performing a type cast; type casting forces a value of one data type to be used as a value of another type.
c. Summing a double, int, and float results in a double.
Final answer:
The false statement is that explicit conversion is always necessary when performing arithmetic operations with operands of unlike types. In fact, Java automatically promotes the operand types as needed. Understanding type promotion and explicit type casting is crucial in Java programming.
Explanation:
The student asked to identify the false statement among three given options related to type conversion and arithmetic operations in Java. Firstly, it's crucial to recognize that Java performs automatic type conversion in certain scenarios when dealing with arithmetic operations involving different data types. This automatic conversion aims to prevent data loss by promoting smaller data types to larger ones.
The false statement is: "When you perform arithmetic operations with operands of unlike types, you must make an explicit conversion to a unifying type." This statement is not entirely accurate because Java automatically promotes one of the operands to the type of the other operand when performing arithmetic operations on operands of different types, a process known as type promotion. However, explicit type casting can be used to override this behavior if desired.
Explicit type casting and the automatic type promotion mechanism are crucial for ensuring accuracy and avoiding errors during arithmetic operations involving different data types in programming languages like Java.
You are researching RAM for a computer you are building for a friend who will be using the system as a home office server for her small business. She wants the added protection so the computer will not crash due to a memory error.
What type of RAM should you consider purchasing?
a) Unbuffered
b) Buffered
c) ECC
d) Registered
Answer:
ECC RAM
Explanation:
ECC RAM is the most popular Random Access Memory out there that is used by most business servers. Dealing with big data for most huge businesses is crucial. The need to prevent loss of data requires that they purchase ECC RAM. ECC RAM automatically protects the systems from potential errors that occur in memory. Any abrupt changes in temporary data stored in ECC RAM are automatically corrected. This is achieved by an additional memory chip that acts as error detection for the other eight RAM chips.
Due to advances in high speed communication networks, the information lag, or the time it takes for information to be disseminated around the world, has been significantly shortened. True or False?
Answer:
True
Explanation:
Latency is a more proper term to describe de the time it takes for a client to send a request and recieve a response form the server. When the latency is too high when playing games online, the user will experience delays and even the game will freeze in the worst cases. This delay on online gaming is what we called lag and can be reduced thanks to the advances in communication networks. Higher bandwitdths are now possible due to network technologies like optical fiber and the implementation of 5G mobile network will also boost data speed for mobile games. It is also true there are other ways to reduice lag that does not require a change to a faster network; sometimes a better use of the network connection is good enough, but it is totally right that faster communication network have reduced information lag and allow users to have access to games than decades ago would have been imposible to play due to network limitations.
A user has just reported that he downloaded a file from a prospective client using IM. The user indicates that the file was called account.doC) The system has been behaving unusually since he downloaded the file. What is the most likely event that occurred?A) Your user inadvertently downloaded a macro virus using IM.B) Your user may have downloaded a rootkit.C) Your user may have accidently changed a setting on the system.D) The system is unstable due to the use of IM.
Answer: A) Your user inadvertently downloaded a macro virus using IM
Explanation:
As the user has downloaded a file from a prospective client ad the file was account.doc, but since then the system of the user has not been behaving normally so the most possible reason could have been the user has inadvertently downloaded a micro virus using the IM. These micro virus are invisible programs which can be transferred inadvertently from one user to another another. They can be transported over the network.
Option b is not correct as the user has not download a rootkit as it would require special privileges.
Option c is not correct as the user upon changing a setting in the system can reset it.
Option d is not correct as using the IM is not unstable to the system.
So, the correct option is A.
When using HTML5 and typing text within the tags of a page, browsers will preserve and display all white space characters (spaces, tabs, newlines) as typed. True or false?
Answer:
Hi!
The answer is false.
Explanation:
The browsers ignore tab indents, double-spaces, newlines, and another typographic formatting when using HTML5.
You can use the tag <pre> to preserve and display typographic formatting as typed.
Furthrmore:
For indent a text, you should use CSS. For spaces, you should use  . For newlines is commonly used the <div> tag.Gateways: a. process all messages, even if the messages are not explicitly addressed to them b. can translate one network protocol into anotherc. are less complex than bridgesd. are most often used as the interface between two or more networks that have similar data link and network layer protocolse. cannot perform a routing function
Answer: B)can translate one network protocol into another
Explanation: Gateway is the element that acts between the two networks that persist protocols that are different from each other. It helps in the translation of one protocol into another protocol and thus it is known as protocol converter.
Other options are incorrect because they don't work on explicit messages, complexity is present in gateways as compared with bridges and is used between dissimilar protocols not data.Thus, the correct option is option(B).
Developers often think of software quality in terms of faults and failures. Faults are problems (for example, loops that never terminate or misplaced commas in statements) that developers can see by looking at the code. Failures are problems, such as a system crash or the invocation of the wrong function, that are visible to the user. Thus, faults can exist in programs but never become failures, because the conditions under which a fault becomes a failure are never reached. How do software vulnerabilities fit into this scheme of faults and failures? Is every fault a vulnerability? Is every vulnerability a fault?
While developing application solutions, software developers are always advised to consider producing secure code that is not vulnerable to hacks. Vulnerabilities, in the simplest of terms, can be described as an error or a fault in code. These errors or bugs, as a result, can cause unexpected actions like system crashes or connectivity issues. Some can go as far as creating information leakage and allowing unauthorized system access. Therefore, it is almost always certain that some bugs will cause vulnerabilities on software that have those bugs in them. It is also fit to say that faults in software are part of a larger list of factors that can cause software vulnerabilities. However, note that not all vulnerabilities are faults.

From which type of data storage does the CPU load information for processing during normal operation?
hard drive
RAM
SSD
ROM
Answer:
RAM
Explanation:
Computers use two kinds of storage: The primary and secondary storage. The CPU interacts with main memory, or the primary storage, or the RAM, by referring to it for instructions and data.
