A brand is the perception of a company. Branding is the effort to influence this perception. A subset of a brand is the brand identity (also called corporate identity or identity system). The key word is identity. These are physical elements you can see when a company communicates with you.
A few of these would be Logo, colors, fonts, icons, letterhead, business cards, envelopes, websites, packaging, uniforms, office aesthetics, promotional swag, social media, email blasts, signage, messaging.
