4.2 Personal Technology and Communication (Tecnología personal y comunicación)

In Spain and most of Latin America, WhatsApp is the default way to message. Families have a group chat (el grupo de la familia), small businesses take orders through it, and voice messages (los audios, las notas de voz) are extremely common. A text about daily life might mention mandar un audio (to send a voice message) as casually as a phone call.

Technology also holds together families split by migration. Millions of people from Mexico, Central America, Venezuela and other countries live far from relatives, and video calls (las videollamadas) let grandparents watch grandchildren grow up from another country. Readings on this topic often present technology as a bridge between people, then ask whether it can replace being together in person.

The other big theme is the cost of being always connected: less sleep, comparing yourself with others, cyberbullying (el ciberacoso) and losing control of your personal data (los datos personales).

Exam texts come from many countries, so you'll see both versions of these words. Either one is correct in your essay; just stay consistent.

• la red social (social network), el perfil (profile), la publicación (post), subir una foto (to post or upload a photo), el seguidor (follower)
• descargar or bajar (to download), la contraseña (password), el enlace (link), la pantalla (screen)
• la privacidad (privacy), compartir (to share), las notificaciones (notifications)
• el algoritmo: the set of rules an app uses to decide what you see next. Readings often explain that algorithms learn from what you watch and click.
• la adicción a las pantallas (screen addiction) and el tiempo de pantalla (screen time)

Phones in school: in 2024, Spain's State School Council (el Consejo Escolar del Estado) recommended banning phones in primary schools and limiting them in secondary schools, and several Spanish regions already had rules. Supporters say students focus and socialize more; critics say phones are useful learning tools and that students need to learn self-control rather than be banned.

Social media and teens: networks help young people find communities and express themselves, but heavy use is linked in many studies to worse sleep and anxiety. A careful essay says "is linked to" (está relacionado con) rather than "causes" unless a source says so.

Privacy: free apps are paid for with your data. Some texts argue that users should control what's collected; others argue that personalized services are worth it.

Texts on this topic often give instructions or advice, and the CED pairs this unit with instructional guidance. Advice in Spanish usually triggers the subjunctive.

• Te recomiendo que desactives las notificaciones por la noche.
• Es mejor que no compartas tu contraseña con nadie.
• Hay que pensar antes de publicar. (Hay que + infinitive = one has to.)
• No uses el celular durante la cena. (A negative tú command uses the subjunctive form.)
