Taken from wikipedia.

Bank:

A bank is a financial institution and a financial intermediary that accepts deposits and channels those deposits into lending activities, either directly by loaning or indirectly through capital markets. A bank is the connection between customers that have capital deficits and customers with capital surpluses.

Due to their influence within a financial system and the economy, banks are highly regulated in most countries. Most banks operate under a system known as fractional reserve banking where they hold only a small reserve of the funds deposited and lend out the rest for profit. They are generally subject to minimum capital requirements which are based on an international set of capital standards, known as the Basel Accords.

Banking in its modern sense evolved in the 14th century in the rich cities of Renaissance Italy but in many ways was a continuation of ideas and concepts of credit and lending that had its roots in the ancient world. In the history of banking, a number of banking dynasties have played a central role over many centuries. The oldest existing bank was founded in 1472.

Pointers:

In various contexts of science, technology, and manufacturing (such as machining, fabricating, and additive manufacturing), an indicator is any of various instruments used to accurately measure small distances and angles, and amplify them to make them more obvious. The name comes from the concept of indicating to the user that which their naked eye cannot discern; such as the presence, or exact quantity, of some small distance (for example, a small height difference between two flat surfaces, a slight lack of concentricity between two cylinders, or other small physical deviations).

Many indicators have a dial display, in which a needle points to graduations in a circular array around the dial. Such indicators, of which there are several types, therefore are often called dial indicators.

Non-dial types of indicators include mechanical devices with cantilevered pointers and electronic devices with digital displays.

Indicators may be used to check the variation in tolerance during the inspection process of a machined part, measure the deflection of a beam or ring under laboratory conditions, as well as many other situations where a small measurement needs to be registered or indicated. Dial indicators typically measure ranges from 0.25mm to 300mm (0.015in to 12.0in), with graduations of 0.001mm to 0.01mm (metric) or 0.00005in to 0.001in (imperial).

Various names are used for indicators of different types and purposes, including dial gauge, clock, probe indicator, pointer, test indicator, dial test indicator, drop indicator, plunger indicator, and others.

Re: HEXADECIMAL

Banks and pointers have nothing to do with hexadecimal numbers.

Rom banks are involved in GB/C so that you can only point into 0x4000 byte data arrays at once. If you need to access data in offset $11A32, you need to access rom bank 0x4 first. Then if you next need to look for something in address 0x28925, you got to do a bank switch since that offset belongs to a different rom bank.

Pointers are things that are used for pointing to data, and they're no way "only GB/C associated". In GB/C, we have only 2-byte pointers which can point to any possible address inside a specific rom bank (that is accessed at the moment), or RAM.
