For a completely regular space , let be the normed algebra of all bounded continuous scalar-valued mappings on equipped with pointwise addition and multiplication and the supremum norm and let be its subalgebra consisting of mappings vanishing at infinity. For a non-vanishing closed ideal of we study properties of its spectrum which may be characterized as the unique locally compact (Hausdorff) space such that and are isometrically isomorphic. We concentrate on compactness properties of and find necessary and sufficient (algebraic) conditions on such that the spectrum satisfies (topological) properties such as the Lindel"{o}f property, -compactness, countable compactness, pseudocompactness and paracompactness.
