Q3 LESSON 1 - COMPUTER NETWORK

 COMPUTER NETWORK- a group of computers interconnected with one another.

TYPE OF NETWORKS

  • PAN (PERSONAL AREA NETWORK)- a computer network that enables interconnection between electronic devices near a person.
  • LAN (LOCAL AREA NETWORK)- a computer network that interconnects computers within a local (limited) area such as a office, building, house, school, campus, laboratory, etc.
  • MAN (METROPOLITAN AREA NETWORK)- a computer that interconnects several LANs together. It covers a larger area of about a city/town.
  • WAN (WIDE AREA NETWORK)- a computer network that interconnects computers which may spread over a large geographical area in the region or country or even the world.
COLLISION- when two or more data packets, transmitted simultaneously over a shared communication medium like cable or Wi-Fi, inference with each other.
NODE- the connection point among network devices as router, printer, or switches that can receives and send data from one endpoint to the other.
BACKBONE- a part of a computer network which interconnects networks providing a path for the exchange of information between different LAN or subnetwork.
HYBRID- any network that can use more than one type of connecting technology.

CHARACTERISTICS OF A COMPUTER NETWORK
-share resources from one computer to another.
-creates files and store them in one computer, access those files from the other computer(s) connected over the network.
-connects a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over the network.

HARDWARE'S REQUIRED TO SET UP A COMPUTER NETWORK
  • Network Cables
  • Distributors
  • Routers
  • Internal Network Cards
  • External Network Cards
COMMON CLASSIFICATION OF NETWORK USED IN COMPUTER SYSTEM SERVICING
PEER-TO-PEER- created when two or more PCs are connected and share resources without going through a separate serve computer.


CLIENT-SERVER NETWORK- computer network in which one centralized, powerful computer (called the server) is a hub to which many less powerful personal computers or workstations (called the clients) are connected.

Q4 LESSON 1 - ASSEMBLY AND DISASSEMBLY

DISASSEMBLY OF PC It is to break down a device into separate parts. A device may be disassembled to help determine as problem, to replace a part, or take the parts and use them in another device or sell them individually. STEP-BY-STEP OF DIASSEMBLY OF A PC   UNPLUGGING . First thing you do is to unplug every cable that is plugged into your computer. That includes the cables such as power, USB, mouse, keyboard, internet, ethernet, modem, etc. Just unplug all the cables for safety purposes. OPENING THE OUTER SHELL/CASE . Unscrew the four screws at the back of the computer. On most computer cases, there will be large knobs that you can unscrew by hand or by screwdriver on the back right side of the computer. The left side has small screws because on that side you can't access much on the inside. Once the screws are removed, you can remove the side panels. REMOVING THE SYSTEM FAN . Unplug the fan from the motherboard. You can find the plug by following the wire from the fan. Next, you ...

Q3 LESSON 3 - NETWORK CABLING

Image
NETWORK CABLES - used to connect and transfer data and information between computers, routers, switches, and storage area networks. These cables are essentially the carrier or media through which data flows.     There are different types of communications cables and the appropriate type to use will depend on the structure and topology of the overall architecture of the system. The most commonly used types of communication cable are dominated by what is referred to as " twisted pair cable ". In local area networks; typically, office environments, retail, and commercial sites, copper communications cabling, i.e., twisted pair cable is by far the most commonly used type of cable. TWISTED PAIR - is used in many ethernet works. Comprising of four pair of thin wires or conductors, these wires or conductors are contained inside of the insulation or outer sheath of the cable. Each pair is twisted into several additional twists. These twists are designed to prevent interference from o...

Q3 LESSON 2 - NETWORK TOPOLOGY

Image
  NETWORK TOPOLOGY - represent the way to connect different computers on network. It comprises of nodes and links. TYPES OF NETWORK TOPOLOGY POINT-TO-POINT - there is a dedicated connection between two ends or devices. It sends or receive signal from exactly one device.  BUS TOPOLOGY - each device is connected through a single cable called backbone of the network. STAR TOPOLGY - this topology no. of devices are linked/connected with a centralized device i.e. Hub or Switch which performs a star shape. RING TOPOLOGY - each device is connected with two other devices to form a ring. TREE TOPOLOGY - this configuration looks like branches of a tree. It is a hybrid topology, combines features of star and bus topologies. MESH TOPOLOGY - each computer and network device is interconnected with one another. It uses point-to-point connection. It is best suited for long distance communication.
