ANSWER:
b) Sequencing
Explanation:
A set of programming blocks that make actions happen one after another. When you have two sprites in your Scratch project they can each have a sequence of programming blocks to make them do something.
Hope it helps u! :)
Error-correcting code memory
Answer:
The storage area network basically apply in the networking model for storage various application in the data center. The storage area network (SAN) provide the common pathway between the server and the storage device.
The storage area network technology basically implemented in the fiber channel configuration over the ethernet. SAN provide access to the data that shared by the personal resources. It is basically simple and dedicated network which provide for the data storage.
Answer: Changes in computer technology have an effect on everyone.
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>
<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.
