A. This is a structural hazard.

B. This is a control hazard.

C. This is a data hazard.

Explanation:

There are various types of hazards that occur in computer architecture based on certain conditions. The memory shared by instruction fetches and data accesses in a Von Neumann memory architecture. This is a structural hazard. A conditional branch instruction in a RISC processor. This is a control hazard.

An integer multiplier that takes two cycles to complete when all other arithmetic operations in a processor take one cycle. Assume that there are sufficient register read and write ports to support all the necessary read and writes per cycle. This is a data hazard.

Data hazards occur happen when the pipeline changes the request for perusing/composing gets to operands with the goal that the request varies from the request seen by consecutively executing guidelines on the unpipelined machine.

A structural hazard occurs when a piece of the processor's equipment is required by at least two guidelines simultaneously.

Control hazards can cause a more noteworthy presentation misfortune for the DLX pipeline than data hazards.

Answer:

From the review select, language, and then change language settings, and select the default language as US English. You need to do nothing else.

Another method is as below:

From File menu, select the "options", and then the language, and install the language if the languages not installed in the proofing section. Once, it shows installed, it means the language has been installed. And then you can change the default language by clicking on "Set the office language preference". Select the American English as default language. You will find that the "colour" is changed to "color" instantly.

An operating system that allows a single user to work on two or more programs at the same time is what type of OS?

Lisa [10]

Answer:

Explanation:

The correct answer is none of these

An operating system that allows a single user to perform only one task at a time is called a Single-User Single-Tasking Operating System. Functions like printing a document, downloading images, etc., can be performed only one at a time. Examples include MS-DOS, Palm OS, etc.

Advantage: This operating system occupies less space in memory.

Disadvantage: It can perform only a single task at a time.

There are four types of operating systems −

Real-time operating system

Single-User/Single-Tasking operating system

Single-User/Multitasking operating system

Multi-User/Multitasking operating system

Real-time operating system is designed to run real-time applications. It can be both single- and multi-tasking. Examples include Abbasi, AMX RTOS, etc.

An operating system that allows a single user to perform more than one task at a time is called Single-User Multitasking Operating System. Examples include Microsoft Windows and Macintosh OS.

It is an operating system that permits several users to utilize the programs that are concurrently running on a single network server. The single network server is termed as "Terminal server". "Terminal client" is a software that supports user sessions. Examples include UNIX, MVS, etc.

The Knowledge Consistency Checker (KCC) ensures the maximum number of hops between any two domain controllers does not exceed wh

Katarina [22]

Answer:

Three (3)

Explanation:

Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;

Domain controller : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.

Hop : A hop is simply the passage of data packets from one network to another. As a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.

The Knowledge Consistency Checker (KCC) : It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.

Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

Hope this helps!
