Which osi reference model layer is associated with common networks (e.g., ethernet lans)?

Answers

Answer 1
OSI stands for Open Systems Interconnection. It is a reference model that enables interconnection between different applications in networks. The model has 7 layers: physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer.
The first - the physical layer and the second data link layer, the network layer is associated with common networks (e.g. Ethernet LANs). The IEEE standard 802.2 describes the physical layer, while the standard 802.3 the second layer.

Answers

Here are three ways:

Cleaning: as applied to most things in our lives, cleaning also applies to protecting peripheral devices. To ensure the smooth running of such devices one needs to clean the dust and dirt from these devices once in a while. Make sure you disconnect the device before you eject it from the system.

Follow instructions: Most devices come with a safety guide and instructions manual, always use the recommended settings for the smooth running of your system. These recommendations usually come from the manufacturer and are reliable.

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.

The part of the data bus that runs between the microprocessor and ram is called the _______ bus.

Answers

The part of the data bus that runs between the microprocessor and ram is called the local bus. A local bus' job is to connect directly from the CPU to one or more slots on the expansion bus. The significance of direct connection to the CPU is avoiding the bottleneck created by the expansion bus, thus providing fast throughput.

The part of the data bus that runs between the microprocessor and RAM is called the data bus. It facilitates data transfer within the computer, allowing components to communicate efficiently.

The data bus transfers data to and from the data registers of various system components, including the CPU and RAM. It serves as the central means for communication within the computer system, allowing different components to share and exchange information seamlessly.

Types of Buses in Computer Architecture

There are three main types of buses in a computer system:

Data bus: Transfers data between the CPU, memory, and other components.Address bus: Carries the address of the data locations that the CPU wants to access.Control bus: Transmits control signals to coordinate and manage the operations of the computer components.

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. .

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)

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.
