6. What are two functions of encapsulation? (Choose two.)

tracks delay between end devices

enables consistent network paths for communication

allows modification of the original data before transmission

identifies pieces of data as part of the same communication

Lecture 4: Network Cabling and Tools

3 Types of Ethernet cable are used in Networking 1-Straight through Cable 2-Cross Over Cable 3-Roll over cable Straight through cable, Cross over Cables are used for data transfer While Rollover cable is used to configure routers / switches / network devices. To remember which type of cable you should use, follow these tips:  To connect two serial interfaces of 2 routers we use serial cable .   To specify when we use crossover cable or straight-through cable, we should remember: Group 1: Router, Host, Server Group 2: Hub, Switch One device in group 1 + One device in group 2: use straight-through cable Two devices in the same group: use crossover cable For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server… and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host HOW TO MAKE A NETWORK CABLE: 1. Unroll the required length of network cable and add a little extra wire, j

The CPU was previously shutdown due to thermal event overheating service the unit right now

Check you system fans are spinning on start up (and they don't stop). Put your computer in the coolest place available, preferably somewhere with air conditioning, and be sure there is space around the box for sufficient airflow. Open the box and remove any dust that has accumulated, particularly on the heat sink and fan(s) blades by using air blower. Blades can get very dirty over time without regular maintenance. The next step would be to remove the heat sink from the CPU (when the computer is off!), Apply silver thermal paste to the cpu and reattach the heatsink and fan. This would improve heat transfer. Determine the temperature of your processor in BIOS or third party tool,normal range from 60-65 ° C for the Pentium 4 While Maximum temperature for the processor is 95 c (Celsius). Processor Overheating Create Following Problems: Reduction of CPU life-span; Random freezes; Random restarts and Shutdown; Eventually the CPU can get burned. Note:Temperature Varies accordin

PTCL Block Porn Websites

Image
Pakistan telecommunication authority (PTA) has recently take stick action against porn, sex, abusive websites and blogs to not open in Pakistan. This action has already applied on all other sub-DSL providers companies. Including, Wateen, Cybernet, Micronet, LinkdotNet, Wi-tribe, Mobilinkinfinity and COMSATS. Ghazi Muhammad Abdullah, a 15-year-old 9th grader, had written to the Chief Justice to take notice of the porn websites, which are easily and freely accessible in Pakistan. Abdullah had approached Chief Justice after failed attempt of convincing IT Ministry and PTA for blocking these objectionable websites on which PTA take Strict Action. Note: Back in October last year, the PTA had issued directives to all broadband operators in Pakistan to block about 1,000 porn websites in Pakistan with immediate effect. Many broadband/DSL operators took immediate action and provided compliance reports (via email) to PTA within a day.
