Networking-devices

Today, one of the most important things you can do is set up your own network. Whether you run your own business or you’re moving into a new home, the rise in the Internet of Things (IoT) mandates the need for a computer network. But, before you set one up, it’s important to understand the different segments and how they work.

The network hub is a LAN device used to connect multiple network hosts and do data transfer. When the host sends data packets, they’re sent to the hub which copies all the packets and sends them to all the ports the hub is connected to. The port for whom the data packet is intended can claim the packet. Unfortunately, a hub is not safe and secure, and copying data packets makes the connection slow and congested.

Network switches work similarly to hubs, but they filter and forward instead of copy and forward. So, when the switch receives a packet, it filters the packet only to the intended receiver. However, as a result, a switch requires the addition of its own content addressable memory (CAM).

Modems are the combination of modulator and demodulator. Normally telephone lines carry analog signals, but computers generate binary data or digital data in the form of 1s and 0s. In order to use the same wires for both telephone lines and internet connection, the modem modulates and demodulates the signal between the digital data of a computer and the analog signal of a telephone line.

Network routers are devices that route data traffic from one network to another. A router works a lot like a traffic police would, directing different network traffic to different directions. Bridges are like network routers, but they connect two subnetworks as part of the same network.

And repeaters are devices that amplified the received signal; they receive signals and retransmit them at a higher level or higher power.

Network devices are important because when your network goes down, all your work is on hold until your internet connection can be reestablished. At Just IT Hardware, owned and operated by ASAP Semiconductor, we know how important it is to stay connected. After all, we are a premier online parts distributor. So, we’re always ready and on standby to help you will all your parts and component related-needs, just visit us at www.justithardware.com to get started on a quote.

networking-devices

Today, being connected is essential to daily life. If you are not connected, it is nearly impossible to function as an individual or business as everything relies on a connected mobile or desktop device. Networking devices are vital to the functionality of a computer. To access the internet, you need to have a networking device so that you can be connected. Different network devices include network hub, network switch, modem, network router, bridge, and repeater. Two of the most common are a modem and a network router.

Modem is short for modular and demodulator. The modem’s purpose is to change the digital data into analog data so that phone lines can be used to communicate and transfer data on your electronic device. The purpose of the router is to direct data traffic from different networks. Without the router, the data would not know where to go and would therefore render the connection useless. The direction of the router makes it possible for computers and devices to stay connected. Routers have the capabilities of a wired and wireless connection. Combined, the networking modem and router are called a network topology. They work in unison to keep devices connected. However, this sometimes isn’t enough. Often limits are reached, and more capacity is needed to stay connected; when this happens, you can add more network devices to sustain the needed requirements for the network. This is called daisy chaining. This keeps devices connected and helps maintain reliability of the network.

Types-of-memory

There are two major types of computer memory which are the primary memory and secondary memory. They both have similar functions but with many different features.

Primary memory:

Primary memory is a volatile memory. This means that anything stored on this will not be permanent. Any part of memory can be saved as data onto the memory, but it will not exist on there forever. Another name for primary memory is RAM, Random Access Memory. RAM will allow the user to add and remove content freely. The only down side of using this choice of memory is in the chance of a power failure, all data will be permanently lost. Some other forms of memory under primary memory is DRAM, SRAM, and DRDRAM.

Secondary Memory:

Secondary memory is the permanent form of memory. This means that counter to the primary method this one is permanent and external. Some examples of what secondary memory may be are floppy disks, magnetic discs, and cache devices. ROM, Read Only Memory is the archaic form of secondary memory, it can store a large sum of content. In case of a power failure, there will be no data loss. The three different external forms of memories are PROM, EPROM, and EEPROM. PROM (programmable read-only) is programmed in a special way, it can write almost any content on the memory, however, it cannot be erased by any program. EPROM (erasable programmable read-only memory) is the improved version of the PROM. This memory can erase the content that you want to remove after it without throwing the entire device away. The user can delete the data of EPROM through pass on ultraviolet light and it erases chip is reprogrammed. EEPROM (electronically erasable programmable read-only memory) is the following improvement made in secondary memory, specifically the EPROM. Using the EEPROM you do not need to use an ultraviolet light to erase the content, but it is possible to remove content freely. EEPROM is now known as Flash memory which is used every day by many computer users.

Internet-of-things

In recent news, Microsoft has launched a new security MCU (microcontrollers) unit for IoT products. IoT stands for internet of things, which are used for interrelated computer devices that are connected via internet, wifi, or bluetooth. IoT products allow you to stay connected to devices and gadgets while physically separated from the device. There are many IoT products on the market that is gaining popularity such as; smart thermostat, home security systems, smart pet feeder, smart washer and dryer and the like. IoT products allow the user to control the device while being away.

As more IoT products are being produced and made available to the consumer, there are some security risks. Since more devices are being used by the internet, wifi, and bluetooth, the information being passed through those mediums are at risk of being hacked and obtained by outside threats. IoT products must be safe to use for the consumer.

Microsoft has provided a solution by developing a microcontroller that can be integrated into IoT products and allow for added security. With the new microcontroller, the user can now run security updates on the device and manage software. Not only is Microsoft offering a wide range of products and services to the customer, the new microcontroller will use Linux OS. By using Linux, it offers a great platform that allows silicon partners to rapidly innovate and use it as a starting point of development. The new system can be used on any cloud service including AWS and Alibaba Cloud.

microprocessor

The first Integrated Circuit was created in 1959 by Fairchild Semiconductor, marking the beginning of microprocessor history that resulted in giving us the advanced computer capabilities we have today. A microprocessor, essentially, is a computer processor that is built on a microchip; its job is to process and execute any instructions it is given. But how does this apply to you? The computer you are using to read this, is employing a microprocessor to transfer data to you.

Microprocessors are extremely advantageous for any computer user. Just a few of these advantages include:

• Low cost– since the cost of making microprocessors is low, the overall cost of the computer system is reduced as well;
• High speed processing– they can carry out millions of instructions per second;
• Small size– allows for a reduction in the size of the computer system as a whole;
• Generates less heat– compared to their counterparts, microprocessors emit far less heat, reducing the chances of your computer overheating.

Microprocessors are made up of a central processing unit (CPU), memory modules, input/output units, and a system bus to keep data moving quickly and effectively. It uses all these components to execute three basic functions:

1. Perform mathematical operations (addition, subtraction, multiplication and division);
2. Transfer data from one memory location to another;
3. Use instructions to make its own decisions.

Since the creation of the microprocessor, there have been five different generations- each faster and more capable than the last.

• 1st generation (1971-1973) – Intel created microprocessor 4004, which only ran at 4-bits, was only able to add and subtract numbers;
• 2nd generation (1973-1978) – progressed to 8-bit processors, carried out through Motorola’s 6800/6801, Intel’s 8085 and Zilog’s Z80; • 3rd generation (1979-1980) – 16-bit processors included Intel’s 8086 and Zilog’s Z8000;
• 4th generation (1981-1995) – Intel’s 80960CA and Motorola’s 88100 were introduced as 32-bit processors;
• 5th generation (1995-present) – low margin, high performance and high speed 64-bit processors; include Pentium, Dual, Quad and Celeron processors.

sandisk memory card

Western Digital has been able to successfully incorporate their resources with SanDisk with their recent merger. As a result of the merger, Western Digital has released what is known to be the fastest UHS-1 flash memory card, creating the 400GB SanDisk Extreme UHS-1 microSDXCTM.

Professionals have successfully included newer traits into the disk while still being able to meet Application Performance Class 2 (A2) Specification, certified by SD Association, a global consortium. Destined to be an extremely enhanced speed disk that may be the answer to increasing mobile device speed.

“Western Digital’s new card features read speeds of up to 160MB/sec and writes at up to 90MB/sec, making it 50% faster than the previous fastest model.”

Many consumers are presented with the issue of lack of device speed due to the flagship of a phones RAM not being able to take in the speed of the removable memory card when used on a mobile device. Western Digital has taken this problem into their own hands to be able to sway the opinion and implement these types of cards for mobile devices once more.

Despite Western Digital recent release, they have continued to present the industry with an new SD card. Sharing similar traits of such as high tech PCIe technology that could be found in the leading PCs and Macintosh computers. With newly designed technology

“The card was demonstrated achieving sequential read speeds of up to 880MB/sec and sequential write speeds of 430 MB/sec.”

Although it has great potential, the card will still need to be further tested for more efficiency upon implementation. Many times, incorporating of such high-powered cards require the generation of much more power along with cooling and newer hardware.

AMD and Nvidia

Gamers are suffering because of digital currency mining. More and more companies are getting their stock eaten up and causing prices to soar. Advanced Micro Devices(AMD), based in Sunnyvale, California and Nvidia, based out of Santa Clara, California, are both struggling to keep their hungry fan base happy. The two companies have been hit hard by the cryptocurrency market. Both of the companies make popular chips used by “miners” to hoard coins, because of this they are buying up the market and an incredibly expedited pace, causing the companies to bump up the price for their normal customers by an insane amount.

Cryptocurrency has been growing rapidly since 2017 and is currently worth more than eight thousand percent of its original price. The online currency once seen only as convenient has turned into a way for many who are low on their luck to make money quickly, if they know how to play the game correctly. With each jump in cryptocurrency comes a jump in demand for cards built by Nvidia Graphics pvt ltd and AMD. There simply is too high of a demand for the companies to build and distribute them at the rate they are each needed. Once the cards hit the market their prices are marked up more than one hundred percent and are still being gobbled up.

Gaming-router

Netduma has been in the works of creating its own type of gaming router for many years and finally found a more efficient solution to its goal. Joining Netgear, they have discovered a way to bring both their resources to create a greater unit. Releasing the latest innovative networking system by the name Nighthawk Pro Gaming XR500 router and Nighthawk SX10 10G/Multi-Gig LAN Switch. The partnering companies have created a router that has the potential to carry out 56 Gbps of bandwidth.

According to the Pcworld.com the XR500 is a

“dual-band AC2600 model supporting MU-MIMO, four spatial streams per frequency band, and beam forming. It’s powered by a dual-core 1.7GHz processor, 256MB of flash memory and 512MB of RAM. There’s a four-port gigabit switch onboard for making wired connections, and two USB 3.0 ports that can be used to share USB storage over the network.”

Netgear was aware of the potential that Netduma had but believed that it could do it a greater good by providing them with top of the line hardware. Bringing together both the software and the hardware was in lue of competing with parallel network companies Linksys and Killer Software.

When requiring more than four ports to be used in your console the switch is required. This will enable users to have gaming port with each user obtaining one for themselves. These ports are often limited to four slots that transmit only one gigabit per slot. The switch comes equipped with eight Gbps on top of two “multi-speed” uplinks that have different kind of variation. The variation that the uplinks can provide are 100Mbps, 1-,2.5-, 5-, and or 10GbE ports.

Currently the switch along with the XR500 are priced at $300 US each, MSRP.

Manufacturer

The Competition Commission of Singapore (CCS) has fined ELNA, Nichicon, Rubycon, and SCC for colluding on pricing for aluminum electrolytic capacitors. The total amount fined adds up to $15 million, which is the most the CCS has ever penalized. Investigations were initiated after Panasonic applied for immunity under the CCS leniency program, which prevents companies that report illegal activity from being incriminated. As a result, Panasonic was the only manufacturer who did not get fined. 1

The five manufacturers are charged with forming a cartel and exchanging sensitive information, such as sales, distribution, and pricing. The companies agreed to set sales prices, including numerous price increases and refusal to accommodate to customers’ requests for price reduction. Investigations revealed that the involved parties met regularly, almost monthly at one point, to exchange confidential information. Activity started as far back as 1997.

Cartels prevent consumers from getting competitive pricing, effectively allowing for a pseudo-monopoly situation in which prices are not driven by the balance of supply and demand. The Competition Act, Chapter 50B of Singapore was enacted in 2004 and regulates cartel activities. The rules are strict, applying to even informal collusions, requiring only that parties arrive at a consensus to be punishable under the Competition Act as a cartel.

Each company was fined based on the proportion of the capacitor supply they controlled. ELNA, Rubycon, and SCC were also awarded discounts to their fines for their application for leniency under the CCS leniency program for coming forth with information on cartel activities.

ELNA was fined $650K, Rubycon was fined $3.6M, and Nichicon and SCC were each fined $5.3M.
