The loader is a program which accepts an object code and prepare them for execution.The loader's target language is machine language, its source language is nearly machine langugae.loading is ultimately bound with storage management function of operating systems and is usually performed later than assembly or compilation.the period of executions of user program is called execution time.the period of translating user's source program is called assembly or compile time. load time refers to the period of loading and preparing object program for execution.
Loading schemes: 1.Absolute loader. 2.Relocating loader. 3.Direct linking loader. 4.Dynamic Loading. 5.Dynamic linking. Absolute loader: The task of an absolute loader is virtually trivial.The loader simply accepts machine language code and places it into main memory specified by the assembler.
Relocating loader: The task of relocating loader is to avoid reassembling of of all subroutines when a subroutine is changed and to perform tasks of allocation and linking for programmer.
Dynamic loading: In order to overlay structure to work it is necessary for the module loader to load the various procedures as they are needed.There are many binders capable of processing and allocating overlay structure.the portion of the laoder that actually intercepts calls and loads necessary procedure is called overlay supervisor of simplly flipper.this overall scheme is called dynamic loading or load on call.
Dynamic linking: This is mechanism by which loading and linking of external references are postponed until execution time.This was made to sort out disadvantage of previous loading schemes like subroutine is referenced and never executed
Implementation of Absolute loader: The four loader functions are performed as following: 1.Allocation- By programmer 2.Linking- By programmer 3.Relocation- By assembler 4.Loading- By loader

What equipments used in quarry mining?
Depends on what is being quarried. If the product is aggregate (gravel), you would use a rock drill, bulk explosives loading trucks, bulldozers, front end loaders, transport trucks, a jaw (primary) crusher, cone mill (secondary) crusher, magnetic separators (to pull out iron and steel scrap) sizing machinery (such as a trommel) and conveyor belts.
What is implementation stage in web design?
Website Designing and Development process includes many steps which will slightly vary from designer to designer but the basic steps are the same which are 1. Information Gathering 2. Planning 3. Design 4. Development 5. Testing & Delivery 6. Maintenance Development will be the implementation stage of whole process because development stage is the point where where website it self is created. Development stage involves the bulk of the programming work, as well as loading content.
How valve point loading effect power system?
Kindle help me to answer What is valve point loading effect and its applcation
What are the factors which influence the choice of specific magnetic and electric loadings of a synchronous machine?
The magnetic loading and electrical loading is most important parameter in the electrical machine. the electrical machine's torque is define as T=winding factor*electrical loading*magnetic loading*rotor volume You can see that the magnetic loading can decide electrical machines volume so this parameter is important.
Discuss what is meant by forward loading and backward loading?
pre planned discussions
Can you use front loading detergent for top loading washers?
Yes you can use. But if the front loading washers, if used with the right detergent are a great investment. You’ll save a lot of electricity and money as a result. Plus, front loaders are more sophisticated technology and hence arguably have been cleaning technology than the traditional top loaders.
What are the class loaders in Java?
A class loader is an object that is responsible for loading classes. The class ClassLoader is an abstract class.
In absolute loading scheme which loader function is performed by programmer?
allocation
Why would people not want to build a quarry near their house?
Dust, sounds from trucks loading from the quarry, skip loaders making sounds,just the constant dust and sounds.
Why do front load washer vibrates excessively?
Front loading washers vibrate more than top loaders because they spin faster. If leveled correctly on a firm surface, however, the vibration should not be excessive.
What are the pros and cons of top-loading washers?
The pros are that top loaders are generally considerably cheaper. You also can't open and close the washer at the last minute to toss in a forgotten item with a front loader. However, front loaders use less water, are kinder on clothes, and can take up less room as you can stack them with the dryer instead of having to have them side by side.
What are Direct linking loaders?
A Direct linking loader is a general relocating loader and is the most popular loading scheme presently used. This scheme has an advantage that it allows the programmer to use multiple procedure and multiple data segments. In addition, the programme is free to reference data or instructions that are contained in other segments. The direct linking loaders provide flexible intersegment referencing and accessing ability.
What are the function of absolute loader?
1. Allocation - by programmer 2.Linking - by programmer 3.Relocation - by assembler 4.Loading - by loader.
What are the four Function of absolute loader?
1. Allocation - by programmer 2.Linking - by programmer 3.Relocation - by assembler 4.Loading - by loader.
What is the only type of gun that doesn't have a bolt or lever on the action that opens the action?
Single shot Muzzle loaders of the "old" style are an example. There is no action to be opened - all loading is done by "stuffing" powder, wading and projectile down the bore of the barrel.
How much water will the GE WSXH208H 3.1 CuFt Front Loading Washer save compared to the top loaders?
The GE WSXH208H 3.1 CuFt Front Loading Washer uses 10 gallons of water for a small load and 15 gallons of water for a large load which can save up to 23 gallons of water per load as compared to a typical washing machine.
