. MCQ from Number 51 100 Answer key. A switch statement is used for which of the following purpose1 to choose from multiple possibilities which may arise due to different values of a single variable2 switch from one variable to another3 switch between functions of a program. Minimize duplication of data and reduce the size of data tables.

When the switch opens the bridge is up and no current flows. Switches that are configured with VLANs will reduce the size of the collision domains by increasing the number of collision domains in a network but making them smaller than that of one big flat network. The most commonly used switch for domestic applications is the one that controls one fixture and has a simple on and off feature.

To remove the starting winding or component from the circuit. The Valsalva maneuver is primarily used to lower blood pressure and heart rate. In an electrical system a switch is used to interrupt or direct the flow of current.

The most basic explanation is that a switch is designed to connect computers within a network while a router is designed to connect multiple networks together. With so many switches available for so many different purposes it is important to understand their distinctions and unique aspects. Increase system performance by creating duplicate copies of the most accessed data allowing faster caching.

And the active list contains in order. Float switches are mainly used for controlling DC and AC motor pumps according to the liquid or water in a tank or sump. A form of general-use switch constructed so that it can be installed in device boxes or on box covers or otherwise used in conjunction with wiring systems.

It is used to observe pulsing magnetic fields which is indicated on the gauge as needle movement Momentary switch- is a switch primarily used to send a voltage signal to a module or controller to request that a device be turned on or off. In the lobby of your building there are three RJ45 ports connected to a switch. An array of electrical switches mounted in one panel that is used to distribute the correct voltage to the circuit in the structures an array of electrical switches.

On what application would you use the following types of electrical enclosures. To measure and monitor pressure. Which is primarily used in the industry today.

Derrick is the network technician for a company that has just upgraded its data center. A switch is like a drawbridge in an electric circuit. 2 General-use snap switch.

In electro-pneumatic controlling systems sensors are primarily used for the following purposes. Dynamic Connection of remote devices. But employees who plug into those same jacks should be able to connect to the network.

You want to make sure that visitors cannot plug their computers into the free network jacks and connect to the network. Increase the amount capacity of valuable data. To detect the presence and position of work piece.

The number of access-layer users. You manage a network that uses switches. When your heart is experiencing tachycardia abnormally fast heart rate blood pressure and heart rate changes as you progress through the maneuver can often restore a normal rhythm.

They connect devices in a network and use packet switching to send receive or forward data packets or data frames over the network. MCQ from Number 101 150 Answer key. Suppose the system uses the SEQ replacement policy we discussed in lecture and initially the inactive list contains.

Solutions for Chapter 9 Problem 31LQ. Derrick is now working on a project to add 10 new desktop computers to the Marketing department. You have been detecting a high percentage of broadcast frames on this LAN.

So the purpose of a switch is to activate or deactivate a circuit at a time of our choosing. Which of the following authentication methods was designed to be used primarily for administration purposes such as giving users access to manage switches and routers. A study of the traffic patterns and flows.

Virtual page C next to be used to fill the inactive list D E and F and other virtual pages are not cached in a physical page. The following sensors are widely used in the industry. A max of 250 access-layer users.

To prevent the motor from starting under heavy loads. The number of servers accessed by the users. The best definition of database normalization is to.

You think the number of broadcasts might be having an impact on network performance. The switches are connected to one another so that all 300 computers can communicate with one another in a single LAN. In other words the switch divides the collision domain of hosts but broadcast domain remains the same.

MCQ from Number 201 250 Answer key. Unlike a router a switch only sends data to the single device it is intended for which may be another switch a router or a users computer not to networks of multiple devices. Even though routers and switches are different they can be used interchangeably.

A network switch connects devices within a network often a local area network or LAN and forwards data packets to and from those devices. This float movement of rod or chain assembly and counterweight causes to open or close electrical contacts. Switches are networking devices operating at layer 2 or a data link layer of the OSI model.

The switch can perform error checking before forwarding data which makes it very efficient as it does not forward packets that have errors and forward good packets selectively to the correct port only. MCQ in Industrial Electronics Principles and Applications. A switch is a data link layer device.

To remove the starting winding or component from the circuit. It is rated in amperes and it is capable of interrupting its rated current at its rated voltage. Switches increases the number of collisions domains in the network.

A switch block should be sized according to which two of the following parameters. MCQ from Number 1 50 Answer key. Virtual page A next to be used for allocation and B.

A switch intended for use in general distribution and branch circuits. To detect the advanced and retracted end position of the piston rod in cylinder drives. During the upgrade Derrick salvaged a number of items including Ethernet cables with the thought that these might be able to be reused at a later time.

To protect the motor from starting overloads. Uses Of The Valsalva Maneuver. Diagnosing an ANS disorder.

This switch is operated when the float or floating object moves downward or upward based on water level in a tank. What evidence can be seen when a switch block. When the switch is closed the bridge is down and electric current can flow around the circuit.

For example a router typically has several LAN ports and a single WAN port. The amount of rack space available.
