What is difference between demand paging n pure demand paging?
In demand paging, a page is not loaded into main memory until it is needed. In pure demand paging, even a single page is not loaded into memory initially. Hence pure demand paging causes a page fault. Page fault, the situation in which the page is not available whenever a processor needs to execute it.
What is dynamic routing?
Routing refers to the process of moving packets of information across a network. Static and dynamic routing are the two types of routing algorithms used for this transfer of information.The term routing encapsulates two tasks. These tasks are deciding the paths for data transferred and sending the packets on these paths. The routing is a process that is a function carried out at layer 3 of the OSI reference model. The routing algorithm decides the output line to transfer the incoming packets. The routing algorithms are based on the routing protocol that uses metrics to assess whether a particular path is the optimal path available for transfer of the data packets. The metrics used for evaluating the paths are bandwidth, delay and reliability. The routing algorithms use these protocols to determine an optimal path from the source to the destination. The routing tables maintain all the information related to routing. There are various routing algorithms and depending on these routing algorithms, the information stored in the routing table varies. Every router has its own routing table and it fills this table with the required information to calculate the optimal path between the source router and the destination router. To understand the basic points of static vs dynamic routing, let us get to know what are routing tables.Routing tableA routing table is a document stored in the router or a network computer. The routing table is stored in the form of a database or is simply a file stored in the router. The data entered in the routing table is referred to when the best possible path to transfer information across two computers in a network is to be determined. The two classifications, viz., static and dynamic routing, are based on the way in which the routing tables are updated every time they are used. The routers in which the data is stored and updated manually are called static routers. On the other hand, the routers in which the information is changed dynamically, by the router itself, are referred to as dynamic routers. Let us compare the two types of routing algorithms based on the static and dynamic routing algorithm used, in the static vs. dynamic routing section given below.Static Vs. Dynamic RoutingStatic routing manually sets up the optimal paths between the source and the destination computers. On the other hand, the dynamic routing uses dynamic protocols to update the routing table and to find the optimal path between the source and the destination computers.The routers that use the static routing algorithm do not have any controlling mechanism if any faults in the routing paths. These routers do not sense the faulty computers encountered while finding the path between two computers or routers in a network. The dynamic routing algorithms are used in the dynamic routers and these routers can sense a faulty router in the network. Also, the dynamic router eliminates the faulty router and finds out another possible optimal path from the source to the destination. If any router is down or faulty due to certain reasons, this fault is circulated in the entire network. Due to this quality of the dynamic routers, they are also called adaptive routers.The static routing is suitable for very small networks and they cannot be used in large networks. As against this, dynamic routing is used for larger networks. The manual routing has no specific routing algorithm. The dynamic routers are based on various routing algorithms like OSPF (Open Shortest Path First), IGRP (Interior Gateway Routing Protocol) and RIP (Routing Information Protocol).The static routing is the simplest way of routing the data packets from a source to a destination in a network. The dynamic routing uses complex algorithms for routing the data packets.The static routing has the advantage that it requires minimal memory. Dynamic router, however, have quite a few memory overheads, depending on the routing algorithms used.The network administrator finds out the optimal path and makes the changes in the routing table in the case of static routing. In the dynamic routing algorithm, the algorithm and the protocol is responsible for routing the packets and making the changes accordingly in the routing table.Nowadays, the static routing is seldom used. With the technological advancements, the dynamic routing is used to route the packets in the network, efficiently. Thus, the above algorithm explains routing, routing tables and static vs dynamic routing.
What do you do if you spelled a word wrong on a typewriter?
Use white out. Besides who uses typewritters any more? Depends on the vintage of the typewriter, and on how finicky you are. Some electric typewriters has an erase function, whioch basically allows you to overwrite the old text with the exact same letter in white. Other mechanical typewriters had the possibility to shift to red lettering, which then could be used to cross out the wrong word and to add the correct one. Another option is simply to back the machine, type XXX over the fault and then continue typing as if nothing had happened. Yet another is to cover the faulty letters with something. Can be either a paint (with Tipp-ex) probably being most well known. Looks a bit like a nail polish bottle but contains something that dries into matte white. Once dried it can be typed on /over again. Or you can have something like a really narrow roll of tape in a fine-tipped applicator, which allows you to tape over the flaws and then type on the tape strip. Yet another way was to use special erasers which were supposed to allow you to erase typewriter text. I never liked those, IME they caused too many smudges.

What is the difference between balanced earth fault and restricted earth fault?
There is such a thing as a three phase to earth fault, so maybe this is what you mean by a "balanced earth fault". I don't believe any earth or ground currents would flow in this case. A restricted earth fault is a typical phase to earth fault, where the zone of protection is restricted to a specific area, such as around a transformer. "Restricted" is referring to the protection method, not what is actually going on with the currents and voltages.
What is the difference between an earthtquake and a fault?
The same as between running and legs.
What is the difference between a let and fault of badminton?
a let is when you give them a point and a fault is when thay force you.
What is difference between the mcb and rcb?
MCB stands for miniature circuit breaker , which provides protection against over current. the setting is not adjustable. RCB stands for residual circuit breaker which provides protection against earth fault as well as over current. It monitors the current difference between phase and neutral and if the difference is more than rated value say 200 milli amps it will trip.
What is the difference between a fault and a fold?
a fault is a large crack in the earth. a fold is when the ground gets bent.
What is the difference between high set and low set over current protection?
in on project that i saw for over current & earth fault protection high set setting had standard inverse curve and low set had l.t.i ( long time inverse) curve
What is the most important difference between fault and joints?
joints have no displacement.
Difference between thrust and reverse fault?
There is a slight difference. A thrust fault is a variety of reverse fault with a dip angle of less than 45 degrees.
What is the difference between an out and fault calls in tennis?
Fault is called only during service (including foot fault) whereas out is called during actual gameplay.
What is vector shift in protection?
Vector shift in protection refers to the change in the phase angle of a fault current waveform when it flows through different protection zones in a power system. It needs to be considered in distance protection schemes to ensure accurate fault detection and discrimination between zones. If not properly accounted for, vector shift can lead to incorrect operation of protective relays and miscoordination between protection devices.
