Computers have changed the way we communicate by introducing email, social networking sites, online chats, instant messaging, Skype, and video calls. Together with the Internet, computers enable people to communicate and receive a prompt response.
The introduction of the computer has allowed technology to replaced traditional forms of communication. Email has replaced letter writing and become commonplace in many organizations. This mode of communication is efficient and allows the sender of the message to send a single message to more than one recipient. Instant messaging, quicker than email, delivers a message in real time as soon as the sender clicks "Enter." This can be good for generating immediate ideas.
Social media, such as Facebook, connects people by allowing mass sharing of life events and daily updates. A "create event" application allows people to invite guests to events without tedious paperwork.
The use of Skype has improved efficiency and communication in the business world. People can easily collaborate on a project. In some cases, job applicants do not have to be physically present for interviews; this can be done via Skype teleconferences.
Computers have also changed the way people shop. Buyers can now place online orders and wait for goods to be delivered.
