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. 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 fan attaches to the heat sink, pulling air through the fins. By dissipating heat drawn into the heat sink, the fan indirectly cools the processor. Types of CPU Air Coolers U-Type/Twin Tower Air Coolers. A commonly used cooler with a vertical stack of heat fins, arranged parallel to the heat base. … C-Type Air […]

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 back into RAM when the process is needed again. Using virtual memory slows the computer down because copying to a hard disk takes much longer than reading and writing RAM. Types of virtual memory: Paging and […]

ANALYSIS OF PROXY SERVERS AND THEIR BENEFITS

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 back? Modern proxy servers do much more than forwarding web requests, all in the name of data security and network performance. Proxy servers act as a firewall and web filter, provide shared network connections, and cache data […]

UNDERSTANDING MAIL SERVER FUNCTIONALITIES AND BENEFITS

Mail Server Definition A mail server (or email server) is a computer system that sends and receives email In many cases, web servers and mail servers are combined in a single machine. However, large ISPs and public email services (such as Gmail and Hotmail) may use dedicated hardware for sending and receiving email. In order for a computer system to function as a mail server, it must include mail server software. This software allows the system administrator to create and manage email accounts for any domains hosted on the server. For example, if the server hosts the domain name “techterms.com,” it can provide email accounts ending in “@techterms.com.” Mail servers send and receive email using standard email protocol For example, the SMTP protocol sends messages and handles outgoing mail requests. The IMAP and POP3  protocols receive messages and are used to process incoming mail. When you log on to a mail server using a webmail interface or email client, these protocols handle all the connections behind the scenes. Mail server software is available for multiple platforms.

ANALYSIS OF NETWORK SWITCHES,FUNCTIONS AND BENEFITS

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.

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 in newer disks that are totally rewritable. Optical storage provides greater memory capacity than magnetic storage because laser beams can be controlled and focused much more precisely than can tiny magnetic heads, thereby enabling the condensation of data […]

UNDERSTANDING NETWORK HANDSHAKE

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 Handshake or “SYN-SYN-ACK.” A successful handshake involves seven steps: Host A sends a synchronize (SYN) packet to Host B. Host B receives Host A’s SYN request. Host B sends a synchronize acknowledgement (SYN-ACK) message to Host A. Host A […]

DYNAMIC ROUTING AND ITS BENEFITS IN COMPUTER NETWORKING

Definition Of A Router A router is a networking device that receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks. How does a router work? Routers guide and direct network data, using packets that contain various kinds of data—such as files, communications, and simple transmissions like web interactions. The data packets have several layers, or sections, one of which carries identifying information such as sender, data type, size, and most importantly, the destination IP (Internet protocol) address. The router reads this layer, prioritizes the data, and chooses the best route to use for each transmission. How do routers help your business? A common tool for modern network computing, routers connect employees to networks, both local and the Internet, where just about every essential business activity takes place.

Error Detection Codes In Computer Network

Error-detecting codes are a sequence of numbers generated by specific procedures for detecting errors in data that has been transmitted over computer networks. When bits are transmitted over the computer network, they are subject to get corrupted due to interference and network problems. The corrupted bits leads to spurious data being received by the receiver and are called errors. Error – detecting codes ensures messages to be encoded before they are sent over noisy channels. The encoding is done in a manner so that the decoder at the receiving end can detect whether there are errors in the incoming signal with high probability of success. TYPES OF ERRORS Errors are normally classified in three categories: systematic errors, random errors, and blunders. Systematic errors are due to identified causes and can, in principle, be eliminated. Errors of this type result in measured values that are consistently too high or consistently too low. What are error detecting codes with examples? Error correction codes also use the similar […]

HOW TO PROTECT YOUR BUSINESS WITH END TO END DATA SECURITY

End-to-end encryption or data security is intended to prevent data being read or secretly modified, other than by the true sender and recipient(s). The messages are encrypted by the sender but the third party does not have a means to decrypt them, and stores them encrypted. End-to-end encryption is a secure line of communication that blocks third-party users from accessing transferred data. When the data is being transferred online, only the sender and recipient can decrypt it with a key. In that way, E2EE can help mitigate risk and protect sensitive information by blocking third parties from accessing user data when data is transferred from one source to another. End-to-end encryption (E2EE) is also a method of secure communication that prevents third-parties from accessing data while it’s transferred from one end system or device to another.

EAVESDROPPING ATTACK AND HOW TO PREVENT IT

Eavesdropping Attack What Is an Eavesdropping Attack? An eavesdropping attack, also known as a sniffing or snooping attack, is a theft of information as it is transmitted over a network by a computer, smartphone or another connected device. The attack takes advantage of unsecured network communications to access data as it is being sent or received by its user. Eavesdropping attacks are an age old security problem. In an eavesdropping attack, the attacker passively listens to network communications to gain access to private information, such as node identification numbers, routing updates, or application sensitive data. The attacker can use this private information to compromise nodes in the network, disrupt routing, or degrade application performance. Cryptography is the standard defense against eavesdropping attacks. However, due to their limited computing power, sensors cannot efficiently process the standard cryptographic keys that are used in typical wired networks. KEY TAKEAWAYS Avoid public wi-fi networks.
