Which device is used to direct the flow of data on a computer network?

. Here is a sequence of addresses during execution of some program: 4, 16, 0, 20, 52, 68, 172, 64 Assuming a fully associative c

Answer:

See explaination for the illustrations on the question.

Explanation:

A program cache miss usually occurs at the instance of an instruction fetch failing to read an instruction from the program cache and the processor is required to access the instruction from the next level of memory. A request to L2 or external memory has a much higher latency than an access from the first level instruction cache.

A cache on its own can be defined as is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory.

Which qualifications are typical for someone working in Marketing Information Management and Research?

Harman [31]

Answer:

• good teamwork skills and knowledge of search engines and social media.

• math skills for calculating prices, good teamwork, and physical stamina.

• a pleasant attitude, critical-thinking skills for designing surveys, and social awareness.

• creativity, persuasiveness, and good social skills when dealing with news media contacts.

Explanation:

Marketing Information Management and Research is a system in an organization whereby skills such as Marketing Information and Research are made use of by marketers to ensure that they come to know who their consumers are , what exactly the consumers want and how they can satisfy the needs and wants of the consumers using a very fast , precise and correct methods.

A person who works in Marketing Information Management and Research must have the following skills:

• good teamwork skills and knowledge of search engines and social media : Accurate knowledge of search engines such as google e.t.c. helps a person working in Marketing Information Management and Research to have access to the latest trends that consumers follow. These trends provides adequate information about the needs of consumers that is required in research.

Good teamwork skills is very important as it makes working in Marketing Information Management and Research very orderly, there is absence of chaos, when working with one another, creative ideas are obtained.

• math skills for calculating prices, good teamwork, and physical stamina : These skills above are very essential because such a person need to have adequate knowledge of the prices of goods and services that they produce. Physical stamina is also and essential skill.

• a pleasant attitude, critical-thinking skills for designing surveys, and social awareness : These qualifications are important because critical thinking helps a such a person to be able to come up with or create a solution using information from the surveys to accurately meet the needs of the consumers.

Having skills in social awareness gives the person working in Marketing Information Management and Research up to date information about what a consumer wants at this particular time or moment.

• creativity, persuasiveness, and good social skills when dealing with news media contacts: These skills are essential because consumers need to see creativity in products and services that they want as it makes them more attractive.

Having good social skills when dealing with news media contacts is also very important.

Given an char variable last that has been initialized to a lowercase letter, write a loop that displays all possible combination

Free_Kalibri [48]

Answer:

for (char i='a'; i<='e'; i++){

for (char j='a'; j<='e'; j++){

cout << i<< j<< "\n";

}

Explanation:

The loop runs all characters from the inner while the outer holds one character, by doing so, a will be matched with a,b,c,... Like wise b,c,d,... and on it goes.

Provided you have an Internet connection and functional Web browser, gather information on three different commercial RAID contr

aalyn [17]

Answer:

1). Serial ATA (SATA): SATA drives are base hard drives. Serial ATA was designed to replace the older parallel ATA (PATA) standard (often called by the old name IDE), offering several advantages over the older interface: reduced cable size and cost (7 conductors instead of 40), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through a I/O queuing protocol. On some systems without a controller, these can be cabled instead to the onboard SATA connections on the motherboard. On smaller servers with a controller, they can still be cabled because these systems will not have a backplane. Cabled hard drives are not hot swappable.

2). Near Line SAS: Near Line SAS are enterprise SATA drives with a SAS interface, head, media, and rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS

drives. This provides better performance and reliability over SATA. Basically it is a hybrid between SATA and SAS.

3). Serial Attached SCSI (SAS): SAS is a communication protocol used in Enterprise hard drives and tape drives. SAS is a point-to-point serial protocol that replaces the older based parallel SCSI bus technology (SCSI). It uses the standard SCSI command set. These have extra connections through the top of the SATA connection. These are the top end in performance for electromechanical drives.

4). Solid-State Drive (SSD): An SSD is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives, which are electromechanical devices containing spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency. Typically because of these features, SSD drives can be the fastest I/O in the market today in standard hard drive form factor.

Suppose that a 2M x 16 main memory is built using 256kB x 8 RAM chips and memory is word addressable, how many RAM chips are nec

hoa [83]

Answer:

16 RAM chips

Explanation:

To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:

Number of RAM chips required = Main memory size / size of one RAM

2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³

Hence:

Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16

Therefore 16 RAM chips are necessary
