A belief is an attitude that something is the case, or that some proposition about the world is true.[1] In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false.[2] To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white").[2]
There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Roderick Chisholm), as interpretive schemes for making sense of someone's actions (Daniel Dennett and Donald Davidson), or as mental states that fill a particular function (Hilary Putnam).[2] Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief (Paul Churchland) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have a belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief").[2][3]
Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?"; "Is the content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H2O part of the content of that belief)?"; "How fine-grained or coarse-grained are our beliefs?"; and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?".[2]

Answer:
Signed numbers represent sign like positive or negative for a number. Unsigned numbers don't store any bit for sign
Explanation:
Signed numbers are the binary numbers where leftmost digit is used to store the sign and the remaining bits used to store the value (magnitude). if leftmost bit of binary number is 0 it is positive number and if it is 1 then it is a negative number
ex: 00110101 represents (+53)
Here 0 (leftmost) represents sign.
Unsigned number is the number which don't have any sign bit. Here only positive numbers we will represent.
ex:0110101(53)
2's complement: This is used to represent signed numbers. we will get 2's complement by inverting the bits of number and adding 1 to it
0111 1110 for 2's complement first invert the number
1000 0001 after inversion add 1 to it then we will get
010000010
