In Slotted ALOHA, time is divided into X-second slots, where X is the frame transmission time, and stations are allowed to transmit only at the beginning of a time slot. Consider a special version of Slotted ALOHA where time is instead divided into 0.5X-second slots; frame transmission time is still X seconds and stations are allowed to transmit only at the beginning of a time slot. What is the length of the vulnerable period for this special version of Slotted ALOHA?

Explanation:

Model.

Explanation:

A computer can be defined as a programmable electronic device that is capable of processing, storing and retrieving data rapidly based on an algorithm. Thus, a computer can be used to easily perform logical operations and mathematical calculations.

Computers are classified based on the following;

I. Size: these includes supercomputers, microcomputers, minicomputers, and mainframe computers.

II. Functionality (purpose): it can either be used for special purpose such as artificial intelligence or general purpose such as word processing.

III. Data handling: it can either be analog, digital or hybrid.

Hence, model is not used to classify computer systems.
