Introduction Data communications (Datacom) is the engineering discipline concerned with communication between the computers. It is defined as a subset of telecommunication involving the transmission of data to and from computers and components of computer systems. More specifically data communication is transmitted via mediums such as wires‚ coaxial cables‚ fiber optics‚ or radiated electromagnetic waves such as broadcast radio‚ infrared light‚ microwaves‚ and satellites. Data Communications =

Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose

Section 1 Introduction 1.1 COMMUNICATIONS Computer communications is the process of sharing data‚ programs‚ and information between two or more computers. We have discussed numerous applications that depend on communication systems‚ including: • E-mail – Provides a fast‚ efficient alternative to traditional mail by sending and receiving electronic documents. • Instant messaging – Supports direct‚ “live” electronic communication between two or more friends or buddies. • Internet

Pascua Course & Year: BSIT-3 Date Submitted: June 24‚ 2013 1. Twisted Pair Wire Physical Specification: -Twisted pair wire is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling outelectromagnetic interference (EMI) from external sources; for instance‚ electromagnetic radiation from unshielded twisted pair (UTP) cables‚ and crosstalk between neighboring pairs. It was invented

As I woke up I felt dizzy. My feet were wrapped in layers of wrap‚ and I was in loads of pain. “Chanel‚ wake up.” My mom said as she tapped on my head. “Why do my feet hurt so much?” I asked confusingly. I didn’t know where I was‚ but I soon realized I was in a hospital room. It was white and small. I saw an IV in me. My mom told me I had had surgery. I broke my toes. After she told me‚ my toes were crooked anyway so it was convenient. It wasn’t very convenient money wise‚ because the surgery
