IT Essentials Chapter 1 - 10 AC Jackson

The best thing to do when a program is crashing or responding very slowly is to open up Task Manager and decide which program is causing a problem. Task Manager provides information about the processes and programs running on the computer, their resource usage, and allows you to end any unresponsive or problematic program. By identifying the specific program causing the issue, you can take appropriate actions such as closing it, restarting the computer, or seeking further troubleshooting steps.

Based on the given information, it is stated that Joynes has the better RAM.

Close-ended questions are best suited for talkative customers, as they typically require short, specific answers. Talkative customers tend to provide more detailed responses and may appreciate the efficiency of close-ended questions, which limit their ability to go off on tangents. By asking close-ended questions, you can gather the necessary information from talkative customers without overwhelming them or wasting their time.

An SLA stands for Service Level Agreement. This is a contract between a service provider and a customer that outlines the agreed-upon level of service that the provider will deliver. It specifies the metrics, such as response time and uptime, that the provider must meet, as well as any penalties for failing to meet these targets. The SLA helps to ensure that both parties have clear expectations and responsibilities, and provides a framework for resolving any disputes that may arise.

POD stands for Ping of Death, which refers to a type of cyber attack where an attacker sends an oversized or malformed ping packet to a target computer, causing it to crash or become unresponsive. This attack takes advantage of vulnerabilities in the target's network stack and can lead to denial of service or system instability. The term "Ping of Death" is derived from the use of the ICMP echo request (ping) packet to carry out this attack.

A Field Service Kit is used for minimizing the risk of ESD (Electrostatic Discharge) that can harm computer components. ESD is a sudden flow of electricity between two objects with different charges, and it can cause damage to sensitive electronic components. A Field Service Kit typically includes tools and equipment that are specifically designed to prevent ESD, such as antistatic wrist straps, grounding mats, and packaging materials. By using these items, technicians can safely handle and repair computer components without the risk of damaging them due to ESD.

A Power Supply Unit (PSU) converts the alternating current (AC) received from the electrical outlet into direct current (DC) which is required by most electronic devices to operate. This conversion is necessary because AC is the standard form of electricity supplied by power grids, while DC is the type of electricity used by electronic devices. Therefore, the correct answer is AC to DC.

IEEE 1394 is the correct answer for the firewire standard. IEEE 1394, also known as FireWire, is a high-speed serial bus standard used for connecting devices such as computers, digital cameras, and external hard drives. It provides a fast data transfer rate and allows for the connection of multiple devices in a daisy-chain configuration. The standard was developed by the Institute of Electrical and Electronics Engineers (IEEE) and has been widely used in the past for connecting multimedia devices.

The correct answer is Berg. A Berg power cable is used in a floppy disk drive. This type of cable has 18 pins and is specifically designed for connecting power to a floppy disk drive. It is different from the Molex power cable, which has 12 pins and is commonly used for connecting power to other computer components such as hard drives and optical drives. The option "a hamster and hamster wheel" is not a valid answer and can be disregarded.

The correct answer is 5 and 4. In the OSI model, the session layer is Layer 5 and the transport layer is Layer 4. The session layer is responsible for establishing, managing, and terminating connections between applications, while the transport layer is responsible for reliable and transparent transfer of data between end systems.

The correct answer is 12Mbps. USB v1.1 has a maximum speed of 12Mbps, which stands for megabits per second. This speed is significantly slower compared to newer USB versions such as USB 2.0, 3.0, or 3.1.

AC Jackson has DDR2 RAM.

The correct answer is PPP and cost of supplies. PPP stands for "Price Per Page" and refers to the cost of printing each page, which includes the price of ink or toner. This is an important factor to consider when buying a printer because it determines the long-term cost of printing. The cost of supplies, such as ink cartridges or toner, is also a significant expense when owning a printer. These ongoing costs should be taken into account when making a purchasing decision.
