HOW TO FIX CPU COOLING FAN NOT WORKING

What is a CPU Fan? The central processing unit (CPU) is the main microchip in a computer, while a CPU fan is the dedicated fan that helps keep the processor cool. Processors generate heat from internal electrical energy. The more demand placed on a CPU, the harder it works, and the warmer it gets. If the CPU gets too warm it can make errors and eventually ‘melt’ becoming completely inoperable. A CPU fan works in conjunction with a heat sink to prevent this. CPU fans often work together with heat sinks to keep a computer cool. A heat sink is a metallic device that sits directly on the CPU, drawing heat away from the chip into its cooler, aluminum, fin-like structure. The CPU

HOW TO ADJUST OR INCREASE VIRTUAL MEMORY IN WINDOWS OS

Virtual Memory Definition Virtual memory is a section of volatile memory created temporarily on the storage drive. It is created when a computer is running many processes at once and Ram is running low. The operating system makes part of the storage drive available to use as RAM. Virtual memory is much slower than main memory because processing power is being taken up by moving data around, rather than just executing instructions. The guide on operating system explains how the OS manages memory. Latency is increased when the computer needs to use virtual memory. Swapping is the process the OS uses to move data between RAM and virtual memory. The OS moves data from processes that are not immediately needed out of the RAM and stores them in virtual memory. It copies the data

PROXY SERVER BENEFITS:5 Reasons Your Company Should Use Proxy Servers

What’s a Proxy Server? A proxy server is a server that acts as a gateway between you and the internet. It’s an intermediary server separating end users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy. If you’re using a proxy server, internet traffic flows through the proxy server on its way to the address you requested. The request then comes back through that same proxy server (there are exceptions to this rule), and then the proxy server forwards the data received from the website to you. If that’s all it does, why bother with a proxy server? Why not just go straight from to the website and

WHAT ARE MAIL SERVERS?

WHAT IS A SERVER? In computing, a server is a piece of computer hardware or software that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model. A server is a computer program or device that provides a service to another computer program and its user, also known as the client. In a data center, the physical computer that a server program runs on is also frequently referred to as a server. That machine might be a dedicated server or it might be used for other purposes. In the client server programming model, a server program awaits and fulfills requests from client programs, which might be running in the same or other computers. A given application in a computer might function as a client with requests for services

What Does Network Switches Do

What is a network switch? A network switch is a device that operates at the Data Link layer of theOSL model—Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach. They can also operate at the network layer--Layer 3 where routing occurs. Switches are a common component of networks based on ethernet fibre channel Asynchronous Transfer Mode (ATM), and InfiniBand among others. In general, though, most switches today use ethernet. A network switch connects devices within a network (often a local area network or LAN*) and forwards data packets to and from those devices. Unlike a router, a switch only

UNDERSTANDING OPTICAL AND MAGNETIC STORAGE DEVICES.

Optical Storage DEFINITION OF OPTICAL STORAGE Optical storage, is an electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage tecnology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface. A low-power laser scanner is used to “read” these pits, with variations in the intensity of reflected light from the pits being converted into electric signals. This technology is used in the compact disc which records sound; in the CD-ROM (compact disc read-only memory), which can store text and images as well as sound; in WORM (write-once read-many), a type of disk that can be written on once and read any number of times; and

NETWORK HANDSHAKE PROCESS

Handshaking Defined Handshaking is an automated process that sets parameters for communication between two different devices before normal communication begins. Much like the way a human handshake sets the stage for the communication to follow, the computing handshake provides both devices with the basic rules for the way data is to be shared between them. These rules can include transfer rate, coding alphabet, parity, interrupt procedure and more. A computer handshake may be completed between any two systems that communicate with each other on the same protocol. The two systems may be a client and server or simply two computers on a p2p network. The handshake confirms the identities of the connecting systems and allows additional communication to take place. Handshaking over a network is commonly called a 3-Way
