Answer:
Const.
Explanation:
In C++ programming language, if you wish to have your compiler deny or prevent access to a member function in modifying (changing) a calling object's private member variables in a line of code, you should declare the member as a const function. Therefore, the member function is simply declared as a constant by the compiler.
The word const at the end of several of the member functions in the accompanying class definition specifies that these functions cannot modify the member variables of a clockType object.
The rightmost digit is the one's digit ( 2^0 ). If it's set, the number is odd, else it's even.
Answer:
1. Processor communication -- this involves the following tasks:
<em>a. exchange of data between processor and I/O module</em>
<em>b. command decoding - I/O module accepts commands sent from the processor. E.g., the I/O module for a disk drive may accept the following commands from the processor: READ SECTOR, WRITE SECTOR, SEEK track, etc. </em>
<em>c. status reporting – The device must be able to report its status to the processor, e.g., disk drive busy, ready etc. Status reporting may also involve reporting various errors. </em>
<em>d. Address recognition – Each I/O device has a unique address and the I/O module must recognize this address. </em>

2. Device communication – The I/O module must be able to perform device communication such as status reporting.
3. Control & timing – The I/O module must be able to co-ordinate the flow of data between the internal resources (such as processor, memory) and external devices.
4. Data buffering – This is necessary as there is a speed mismatch between speed of data transfer between processor and memory and external devices. Data coming from the main memory are sent to an I/O module in a rapid burst. The data is buffered in the I/O module and then sent to the peripheral device at its rate.
5. Error detection – The I/O module must also be able to detect errors and report them to the processor. These errors may be mechanical errors (such as paper jam in a printer), or changes in the bit pattern of transmitted data. A common way of detecting such errors is by using parity bits.
Never add tap water to your battery. ... Battery electrolyte levels should be just below the bottom of the vent well, about ½ - ¾ inch above the tops of the separators. Never let the electrolyte level to drop below the top of the plates.
