What is the range of the well-known ports used by tcp and udp?

Answers

Answer 1
/etc/services on my CentOS machine goes up to 49000. Reserved ports are less than 1024.

Well known and reserved ports are two different things. Well known ports only need a registration with IANA. Reserved ports, on *nixes, requires root for a deamon to bind to the port.

Most windows computers typically use _____, which supports much larger hard drives and files than the older fat32 and includes better security and error-recovery capabilities.

Answers

NTFS NTFS (NT File System) is the file system that the NT operating system introduced in Windows NT 3.1 in 1993. It is a "journaling file system" which means that intentions for changes to the file system are first written to a special journal, then the actual changes are performed to the file system. This allows for NTFS to better recover from errors caused by power loss. The maximum theoretical size of a NTFS volume is 2^64 - 1 clusters with a cluster being typically 4KB long, although it can be as long as 64KB. The maximum length of a file in NTFS is 2^64 - 1024 bytes long. In contrast, the volume size limit for a FAT32 system is 2 terabytes using 512 byte sectors, or 16 terabytes using 4096 sectors and a maximum file size of 2^32 - 1 bytes.

Which four of the following hardware components are used to enable networking and are not part of a standalone computer? NIC protocols hub monitor mouse router switches printers

Answers

NIC, hub, router, and switches are the hardware components used to enable networking and are not part of a standalone computer.

Hope that helps :)

Answer:

NIC, hub, router, and switches

Explanation:

NIC (or network card) has the function to prepare, send and control data to the network. A network card serves as a physical interface between the computer and the cable. It prepares data output from the computer to the network cable, transfers it to another computer, and controls the flow of data between the computer and cable. It also translates the data coming from the cable and converts it into bytes, so that the computer's Central Unit understands it.Hubs are used to connect the various devices that make up a network, computers, printers, or others. The term hub is used to refer to a network device that connects computers to each other, but in reality it also serves as a repeater, because it passes or repeats all the information it receives to all its ports.A router is a device that connects several normally different segments on a single network. Once a router is turned on, it can make smart decisions about how to get the data to its destination based on the information it gets from the network itself.Switch - Like the hub, the switch connects multiple segments of a network, but with one major difference: while a hub distributes information across all ports simultaneously, the switch establishes a direct link between the sending device and the receiving device. .

Final answer:

The scenario illustrates a finish-to-start dependency in project management, where one task must be completed before the next can begin, highlighting the importance of understanding task dependencies in planning.

Explanation:

The question describes a scenario where a server must operate in a laboratory setting for five days without any failures before it can be moved into a data center. This situation exemplifies a dependency in project scheduling, specifically a finish-to-start dependency. In project management, dependencies dictate the order in which tasks must be completed. A finish-to-start dependency means that one task (in this case, the server running successfully in the lab for five days) must be finished before the subsequent task (moving the server into the data center) can begin.

In constructing a project timeline, recognizing and planning for these dependencies is crucial. Whether managing a simple project or orchestrating complex operations in a data center, understanding task dependencies helps in allocating resources efficiently and avoiding project delays. Consequently, this enables a smoother workflow and better project outcomes.

Java compiler translates java source code into ________. question 11 options:

Answers

Answer:

bytecode

Explanation:

     Java compiler translates java code into an intermediate representation called bytecode. The bytecode in turn is executed on a Java Virtual Machine (JVM). The structure of the bytecode is standardized and forms part of the JVM specification.

    This is different from other programming languages like C/C++ where the source code is  compiled to executable which runs directly on the processor.

Java compiler translates java source code into Bytecode.

Bytecode is a low-level representation of the Java code that is platform-independent.

It is a set of instructions that can be executed by the Java Virtual Machine (JVM).

When you compile Java source code using a Java compiler, it converts the human-readable Java code into bytecode, which can then be executed by the JVM on different platforms, such as Windows, macOS, or Linux.

The JVM interprets and executes the bytecode to run the Java program.

How many bits would you need if you wanted to have the ability to count up to 1000?

Answers

For every bit you can record two possible data and the amount will increase by rate 2^x where x is the number of bit. To answer this question, you need to know what is the least amount 2^x that will be enough to record 1000 possibilities.
To do this, it is easier to divide the number with 32 for 5 bits(2^5=32), then divide it with 2 for 1 bit until it less than 1. The calculation would be: 1000/32= 31.25 /32= 0.976.
The answer would be 5 bit+ 5bit= 10 bit. (2^10= 1024)

what is an ad's target audience composed of

A. The few people who paid for the ad

B. The many people who created the ad

C. The people advertisers hope to reach

D. The people the ad features or pictures

Answers

C. An ad targets an audience the creators hope will but the product.

Final answer:

The correct answer is "The people advertisers hope to reach". The target audience of an ad is composed of the people that advertisers intend to reach and who are most likely to be receptive to their marketing message. This group is identified through analysis of demographic, psychographic, and behavioral characteristics. Ads are designed to appeal to the sensibilities of this audience, using visual and verbal cues strategically.

Explanation:

The correct answer to the question 'what is an ad's target audience composed of' is C. The people advertisers hope to reach. An ad's target audience is a specific group of consumers that advertisers have determined are most likely to respond positively to their message. Determining who the ad is designed for involves looking at factors such as demographics, interests, and behaviors. It could be designed for people from a particular political party, economic class, age group, or even people with specific interests or needs.

To understand who is pictured in the advertisement and who is left out can offer insights into the target audience. For example, if an ad for a luxury car features well-dressed individuals in an affluent setting, the target audience is likely high-income earners who value prestige and luxury. The people presented in ads are usually depicted in a manner that appeals to this target audience, which can be inferred from their expressions, the direction of their gaze, and even the camera angle used.

A target audience consists not only of individuals who will directly respond to the ad, but sometimes includes a secondary audience. These are individuals who may influence the primary audience or take actions that the ad seeks to encourage, such as philanthropists supporting a cause advertised, or legislators who could enact change based on the ad's message.

Ultimately, a target audience includes anyone capable of being persuaded and capable of creating the change that the advertiser seeks.

_____ does not allow changing service or bandwidth because a website allows illegal media sharing

Answers

Final answer:

Net Neutrality does not allow changing service or bandwidth because a website allows illegal media sharing.

Explanation:

Net Neutrality ensures that internet service providers treat all online data equally, prohibiting discrimination or favoritism. It doesn't permit altering service or bandwidth based on the content of websites, including those facilitating illegal media sharing. Upholding Net Neutrality principles means ISPs can't selectively throttle or block access to specific sites or services.

Instead, they must provide consistent and nondiscriminatory access to all online content. This ensures fair and open access to information and services for users, regardless of the nature of the content they access. Thus, Net Neutrality safeguards against arbitrary restrictions based on the legality or illegality of online activities.
