LinkedIn is also for social networking but only for professionals. You network with colleagues and acquaintances to discuss the job market and upload your resume in the hopes of finding a better job that suits you well. LinkedIn should be logged in at home, not at the workplace where you should stick to your current work projects so that you get good recommendations from higher-ups when you attempt to shift to a new job.
Adobe Photoshop, Word and PowerPoint can be daily requirements at work for image edits, documentation and presentations. These are really helpful tools which help to enhance your work. Skype and Viber are the digital tools to communicate with distant colleagues at another branch or a Boss away from work.
