Bookshop Manager Essay Example

physical memory size is 512MB, allowing for running multiple applications simultaneously. It is also advised to have a hard drive capacity of 40GB - 80GB for storing large files and book records. This system offers the advantage of speed and efficiency, but a disadvantage is that Jeremy and the staff need to manually enter information about every book into the system, which can be challenging. Hiring a professional IT specialist could benefit the shop by handling technical issues and saving time for others. Despite Jeremy's computer expertise and the proficiency of the rest of the staff, having a specialist could provide valuable assistance.

The bookshop provides a range of services, including order taking and book holding for customers unable to make immediate purchases. As an authorized company, the shop is allowed to store essential customer information, such as names and addresses, on their computer system. This data is securely stored and it is the responsibility of the shop to maintain its confidentiality and not disclose it without proper consent in order to comply with the Data Protection Act (1998). Unauthorized access to this data would be considered a violation of the Computer Misuse Act (1990). Additionally, excessive computer usage can result in health problems like hand and back issues, which contradicts the guidelines outlined in the Health and Safety at Work Act (1974).

Due to its small size, the bookshop only possesses a single till. As a result, there is a computer upstairs that can be utilized for general purposes, while another one is located downstairs in the offices for more significant and specific tasks - like monitoring eBay. However, the issue is that these computers are

not interconnected. If they were networked, communication and data transfer would become considerably simpler.

Currently, they use a zip drive to transfer data and walkie-talkies for communication. On a network, messages can be sent and data can be stored on a central server computer that can be accessed by everyone.

Internet

The internet is a global network that connects numerous computers. It enables computers to access data on other computers. When people talk about the "Internet," they usually mean the World Wide Web, which is an information system that depends on the Internet to retrieve data stored on computers worldwide.

Jeremy has multiple options for obtaining information about books and their prices. He can visit a specialized book website online, or he can choose to purchase books from Amazon or EBay. However, caution is advised when buying from EBay due to the risk of illegal theft that may result in financial loss or loss of the purchased item. It is crucial for Jeremy to trust the seller before making a purchase. In terms of his internet connection, Jeremy utilizes an Askey 1456VQL1V-1 (INT) 56K modem to connect to the internet. A modem is an electronic device that converts computer signals into analog signals so that they can be transmitted via a telephone line. To access the internet, he subscribes to Onetel, which offers affordable internet services.

They offer unlimited downloads and a 10MB upload limit. The modem's connection speed is determined by its bandwidth, which refers to the amount of data that can be transmitted within a specific time frame. Bandwidth is typically measured in bits per second (bps) or bytes per second for digital devices. Analog devices measure bandwidth

in cycles per second or Hertz (Hz). One advantage of this method is the capability to connect to the internet using any phone line and at any given time. However, there are disadvantages as well: only one computer can access the internet at once, and the cost depends on usage minutes, so keeping it on could result in costly bills.

Jeremy's main challenge is the slow connection speed of 56 kilobits per second, which is significantly slower than today's speeds that can reach up to 4 megabits per second (4,000,000 bits). This limited bandwidth greatly affects Jeremy as he heavily relies on the internet for his work. To improve his situation, Jeremy should consider upgrading to broadband. Broadband is a communication medium that uses wide-bandwidth channels for efficient transmission and reception of large volumes of data, video, or voice information. Unlike a phone line, broadband uses a digital cable specifically designed for internet connectivity, allowing multiple users to be online simultaneously.

Broadband provides several benefits, including continuous connectivity and no additional charges with NTL's monthly payment plan. However, there are drawbacks to broadband as well. The installation may necessitate a financial investment and it is limited to the particular broadband connection.

Mobile Phone

A mobile phone is a portable device that operates similarly to a regular telephone but can be utilized in various locations. When initiating a call, the phone transmits a signal to the nearest receiver, which subsequently relays the call through the mobile phone network.

The call is transmitted and the other phone is found. Mobile phones enable connections to be established with the telephone network through direct dialing on a built-in keypad. Presently, mobile phones utilize a

combination of radio wave transmission and traditional telephone circuit switching; however, packet switching is already being used in certain areas of the mobile phone network, particularly for services like internet access and WAP. Jeremy possesses a relatively new phone, the Nokia 3200, which offers numerous features that enhance his social life.

Jeremy has an advantage because Nokia is the most popular phone manufacturer and offers many features for his social life. He can use multimedia messaging to send photos and videos to other compatible phones. Additionally, his phone has a camera and memory, allowing him to capture moments and store them. Jeremy's service provider is Vodafone, which handles phone calls and operates mobile phone masts for signal reception.

Vodafone provides extensive network coverage, ensuring a strong signal in most areas. However, it may be more expensive than other service providers. Jeremy has two choices for paying his mobile phone calls and texts. The first choice is pay as you go, where he adds credit to his phone and uses it until the balance runs out. The second choice is a monthly payment plan that offers unlimited phone usage, with the bill calculated based on the total spent at the end of each month.

A pay-as-you-go plan has the advantage of not needing phone recharging and having no credit limits. However, it requires registration and bill payments. On the other hand, using a SIM card eliminates the need for detailed registration. Currently, Jeremy has a monthly payment plan with 120 minutes and 30 texts but finds this inconvenient as he doesn't fully utilize these allowances. Therefore, switching to a pay-as-you-go plan would be ideal for him due to nearby

top-up locations. Jeremy prefers topping up with small amounts since he doesn't use his mobile frequently. Sticking with Vodafone is recommended in this case because they offer top-ups starting from ?10 and even rare ?5 top-ups. However, if Jeremy wants a cheaper service provider despite potential lower quality service and network coverage, Tesco is an option. Additionally, if he desires additional features and promotions like Orange Wednesdays where users can bring friends to participating cinemas for free on Wednesdays, Orange is a good choice.

MSN Messenger is a communication tool utilized by Jeremy to connect with his friends and family. It is an instant messaging system developed by Microsoft referred to as the .NET Messenger Service. This service, along with Microsoft's Passport system, permits users to send online messages to one another. While primarily employed for instantaneous messaging, MSN Messenger also supports voice conversations, webcams, file transfers, and multiplayer online games like Tic Tac Toe. Similar to its rivals, MSN Messenger allows users to enhance their messages with graphical emoticons (smileys), Flash animations known as winks, animated display pictures, different text styles, and additional features through add-ons. The advantages of utilizing MSN Messenger include its accessibility, lack of cost incurred, and absence of extra charges.

MSN Messenger is a fast, efficient, and secure option. However, it may result in vague communication and excessive chatting, which could be a waste of time. Jeremy could also consider using ICQ or AOL Messenger. Nevertheless, MSN Messenger is likely the most favorable choice due to its extensive user base.

Microsoft, the richest company that developed a chat program, has a larger number of skilled programmers dedicated to enhancing MSN Messenger.
