A computer case, also known as a computer chassis, is the enclosure that contains most of the components of a personal computer (usually excluding the display, keyboard, and mouse). Cases are usually constructed from steel (often SECC-steel, electrogalvanized, cold-rolled, coil), aluminium and plastic. Other materials such as glass, wood, acrylic and even Lego bricks have appeared in home-built cases. Cases can come in many different sizes (known as form factors). The size and shape of a computer case are usually determined by the form factor of the motherboard since it is the largest component of most computers. Cases are also referred to by their size (such as ATX case, Mini ITX case, etc.) Consequently, personal computer form factors typically specify only the internal dimensions and layout of the case. Form factors for rack-mounted and blade servers may include precise external dimensions as well since these cases must themselves fit in specific enclosures.

In a byte-addressable machine with storage-to-storage (SS) instructions, there are typically move instructions to copy one or multiple bytes from one arbitrary location to another. Individual bytes can be accessed on a word-oriented machine in one of two ways. Bytes can be manipulated by a combination of shift and mask operations in registers. Alternatively many word-oriented machines implement byte operations with instructions using special byte pointers in registers or memory. For example, the PDP-10 byte pointer contained the size of the byte in bits (allowing different-sized bytes to be accessed), the bit position of the byte within the word, and the word address of the data. Instructions could automatically adjust the pointer to the next byte on, for example, load and deposit (store) operations. Different amounts of memory are used to store data values with different degrees of precision. The commonly used sizes are usually a power of two multiple of the unit of address resolution (byte or word).
Binary numerals were central to Leibniz's theology. He believed that binary numbers were symbolic of the Christian idea of creatio ex nihilo or creation out of nothing. After his ideas were ignored, he came across a classic Chinese text called I Ching or ‘Book of Changes’, which used 64 hexagrams of six-bit visual binary code. The book had confirmed his theory that life could be simplified or reduced down to a series of straightforward propositions. He created a system consisting of rows of zeros and ones. During this time period, Leibniz had not yet found a use for this system. Binary systems predating Leibniz also existed in the ancient world. The aforementioned I Ching that Leibniz encountered dates from the 9th century BC in China. The binary system of the I Ching, a text for divination, is based on the duality of yin and yang. Slit drums with binary tones are used to encode messages across Africa and Asia.
Objects are built by stating true facts about them. Set theory facts are formed by assigning objects to sets. The syntax is setName(object). Cat is an animal. Mouse is an animal. Tom is a cat. Jerry is a mouse. Adjective facts are formed using adjective(object). Relationships are formed using multiple items inside the parentheses. In our example we have verb(object,object) and verb(adjective,adjective). Big animals eat small animals. Prolog's usage has expanded to become a goal-oriented language. In a goal-oriented application, the goal is defined by providing a list of subgoals. Then each subgoal is defined by further providing a list of its subgoals, etc. If a path of subgoals fails to find a solution, then that subgoal is backtracked and another path is systematically attempted. Object-oriented programming is a programming method to execute operations (functions) on objects. The basic idea is to group the characteristics of a phenomenon into an object container and give the container a name.
