الفرق بين كوابل الإيثرنت Ethernet Cables
Cat1:نقل الصوت فقط.
Cat2:نقل بيانات 4MB/S.
Cat3:نقل بيانات 10MB/S.
Cat4:نقل بيانات 16MB/S.
Cat5:نقل بيانات 100MB/S.
Cat5e:نقل بيانات 1Gb/S اعتماداً على طول السلك ونوعية السويتش.
Cat6:نقل بيانات تصل إلى 1GB/S و أكثر.
سبب وجود كل سلكين ملتويين هو تفادي التداخل المغناطيسي، حيث أن كل سلك من السلكين الملتويين يكون له اتجاه مغناطيسي عكس الآخر.
النوع الآخر من هذه الكيابل هو STP أو Shielded Twisted Pair، وهي أسلاك ملتوية محمية بطبقة من الألومنيوم تحت الطبقة البلاستيكية الخارجية؛ وتتميز عن الـ UTP بأنها :
◊ أقل عرضة للتداخل المغناطيسي.
◊ تدعم مسافات أطول في بعض الظروف.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
